Explanation of ESP Experiment
I have received various possible explanations for how the ESP
web page works. I welcome your own suggestions for how this
This ESP Test has recently taken the world by storm.
On June 5th, 2002 the popular UK newspaper the Daily Mirror
reported on my web site:
"It's got to be one of the weirdest sites we've ever come across but it's definitely worth visiting. Pop into http:// sprott.physics.wisc.edu/ pickover/ esp.html and you'll be baffled for days - even months. We don't know how he does it but Cliff Pickover, the site's creator, claims he's conducting an ESP test. Click on one of three eyes, he asks, and then look at six playing cards. Without moving your cursor, pick a card, shout out its name and then click on one of six more eyes. It then tells you which card you chose. It claims to be correct 98 per cent of the time but won't tell you how. Every one of the 60 times we tried - and we did everything we could to trick them - they got it right. Spooky!" (page 45)
This ESP Test is now used throughout the world in Psychology and other
university classes. As one example, note how it was used as
an extra-credit problem in a university "Psychology 101" class:
Pickover's ESP website says it's "psychic." Follow the
directions given and see if your mind was read correctly
or not. What you will give me is a sentence or two
stating whether you would conclude this website
is psychic and that it could read your mind.
Ten points possible. Due November 27, 2002.
Here are some individual explanations of the astounding results....
From Karen G.
I think your ESP experiment works because most people choose a
card too quickly and don't give the computer sufficient time to
randomly choose other cards. Also, the thought occurred to me that
people may tend to mouse-click on the side of the screen where their
chosen card is located, so that the computer can eliminate some of the
cards as potential choices.
From Angela R.
I tried the esp experiment about 50 times consecutively and it gave the correct answer every time. I intend to repeat the experiment and count properly, but the p-value is already low enough to convince me that this is not change guessing.
I was using the random number generator on my calculator to choose which card to pick, and I clicked the same eyes every time, and I put my cursor over the eye which I was to click before I pressed the random button on my calculator so that I could be sure that the website was not using my cursor movements to predict the card. I put a black sock over my webcam hole, to ensure that the site was not tracking my eye movements, and was careful not to make the sort of noises that might reveal what card I was looking at should my microphone be hijacked.
How does it work? The html code that I read did not inform me of where cards2.gif came from. Do you have any other source code that I can view?
From Elaine V.
I only did the test twice. But how do you do that.
I think it has something to do with the eye square that was installed on my computer against my will and I can't get rid of.
Is it that indeed, does the computer scan our eye movements.
Since I don't have a web cam, how does it do that.
Or is it strictly a mathematical probability and random
type of thing?
I am curious.
From Milica H.
Dr. Pickover, regarding the ESP test,
in one case you guessed correctly and
once you were wrong - and I
did the ESP experiment
Does the explanation have something to do with clicking on eyes icons before and after
we have chosen the card? I think there is a calculation of
The choice of eye icon could give you a clue which card we choose. Or
at least that is my theory as to how it works.
Anyway, quite impressive! Will you announce the results of ESP
experiment? Best wishes, Milica, Researcher
From Linda W.
I think the ESP program works because the computer can guess your
selection by monitoring which eye and blinking eye you select.
There must be a formula that maps eye and tarot card selection to the
card you selected.
From Stephanie S.
I really enjoyed the ESP Experiment. I have a theory as to how it works:
One card is
slightly "darker" and shadowed, and gives the impression of being at a
slightly lower level than the others in a 3D sense. I think you are
therefore drawn to pick that card. Looking forward to hearing the
From Larry S.
I viewed the source code and could not discover understandable
computations which would aid the web page in making a decision.
However, I did note that if the user does not look at the card layout
(thus denying the "web site" the opportunity to follow the user's eye
movement), and that if the user decides beforehand which card to
choose, that the ESP program fails to determine the user's card
Does the technology exist that would: (1) allow interaction between
a server/program and a user to the extent that the server/program
could scan the user's eye movement; (2) and, precise enough to detect
pupil dilation resulting from concentration?
From Tara R.
Quantum mechanics may permit synchronicity of thought and
computer software. I suggest that, on the quantum level,
you were able to predict the card I selected even before
I selected it. It is also possible that my brainwaves
may influence your software. Although this seems far-fetched,
we know that brainwaves are detectable with SQUID (superconducting
quantum interference devices.)
Yes, you picked the right card. I wonder how you did that. I shall spend
many nights wondering this.
I thought of 2 cards actually, and your program picked the one that I
thought of first. By thinking of more than one card your program's odds
of picking the correct one are greatly improved in my case. Maybe your
program preys on peoples inability to make up their mind. Anyway I still
don't know how you did it. Facinating.
From Doug L:
The ESP experiment "worked", i.e. the web site appeared to correctly
determine the playing card I selected.
Knowing that you have written a book on time travel, I suspect
that the original tarot card selection is a ruse, and that I in fact
randomly selected a playing card, a selection that you had 5/6
probability of guessing wrong. In other words, you have discovered a
limited (but real) mechanism of modifying past events .
My suspicion is that "originally" the experiment failed, but with
each subsequent failure you were able to modify my previous
experiences until, after a few iterations, you were successful.
Can you modify "physical" past events, or is your method
restricted to thoughts and perceptions?
From Samantha F.:
I believe you are able to determine which card I picked by examining
my eye movement (point of reference
- eyeball) and card location?
My boyfriend and I found out by trying the
At first, we thought you could simultaneously detect both our
By the way, I am an eighth grade science teacher. I use your
Alien IQ Test book on my students. They love it! Any further suggestions?
From David S., Associate Professor of Chemistry:
I enjoyed your esp experiment. Yes, you correctly predicted my selection
two times in a row. I think I know how you do it: each day, you ingest
a small amount ( several mg.) of Harmine alkaloid which is sometimes
called Telepathine. Check this out in the Merck Index.
You might want to write a book on pyschactive compounds. Very
From Clay F.:
One card flickers and subliminally calls your attention to it.
From Marcela S.:
Okay-- that was way too freaky for me!!! I do admit it was
awesome but at the same time it scares me because it seems that there
is no limit to the power of our minds -- or yours at least -- that could
be good or it could be bad. Have you ever considered that we may not
be meant to use all the power our brain has because it could lead to
our destruction?? Just a thought!! Thank you!!
From Mark M.:
experiment was correct. You scare me. I scare myself sometimes. I
lucid dream often and have more than dejavue occurrences.
From Guy B.:
I am quite impressed, Mr. Pickover. I am quite sure that the other
explanations for why your little ESP program works are totally
incorrect, however, I am at a total loss, especially since I did the
best I could to generate random numbers. I couldn't find any dice handy,
so I used the Time of Day clock on my computer, and found its remander
when divided by 3 for the first number; took out the first business card
that came to hand and took the first phone number on there modulo 6, and
then located a calculator and had it generate a pseudo-random number
which I then did modulo 6.
I did the little experiment 3 times, and your program "got" it all
times. And, no, I did not say the name of the card aloud or stare at it
or anything like that; it has nothing to do with what side of the side of the screen
I clicked on.
As I said before, I am quite impressed. I do not at this point know how
to download and disassemble Java code, unfortunately, or maybe I could
figure out how you did it. (Assuming you wrote this in Java.)
From Kari H.:
Heh, when I found your esp page there was two other
physicists in the office and we were all wondering how can
this be true, what's the trick. A collegue look at page
source code and tried to mess around with mouse
pointer to see if it had any influence. After reading
the 'flicker explanation' by Clay F. a card was selected by
one of us choosing a number between 1 and 6 without looking
at the monitor and the other was on computer an an 'operator' :)
It was fun.
From Ryan M.:
This is Ryan, one half of Karen and Ryan who discovered your ESP
We're both college students at Sir Sandford Flemming College in
Lindsay Ontario, Canada. We spent a good hour or so trying to figure
out how that trick worked, some of our theories involved: a program
that tracked eye movements, mind reading web pages, artificial
intelligence, one of those cool programs that evolves to predict
stuff through natural selection, and even a little anti-chaos theroy!
I have recently read your collaboration with Piers Anthony "Spider
Legs". It was splendiferous! Right up my ally too, as I am an
Aquaculture student. You have caused me to become obsessed with Sea
Spiders, I am in fact; using them as a subject for a class paper.
Professor Margaret C.
I don't know how the ESP works, but I tried clicking on the same eyes before
and after each time and then thinking of a different card without saying
it out loud. It got it right 4 times out of 4, which statistically is
improbable but not impossible. I always thought I had ESP!
I am an atomic physicist and professor of IT in Education. When I have
more time I would like to experiment further.
Well done on a very clever site!
From: Tim G.:
Nice, I'm impressed with the ESP page. I suspect simple statistics
is the explanation to how it works.
If I click the same "eyes" then your program
removes the same card each time (no matter how
hard I stare at different cards/out of the window!).
This suggests a static mapping between eyes clicked
and card removed (or a mapping that changes
very slowly). I like the idea of the program
learning these mappings. I can only assume that
the feedback mechanism is based on people going
for another "try" only if the program gets it
right first tme round, so if a user has another
go the program assumes that it got it right
first time. It only remains for me to state my
amazement/dismay that we are so predictable!!
I tried three times and you missed twice. Better luck next time.
From Larisa K:
May I submit that your interesting 98-percent accuracy and impressive Quantum
Consistency numbers result from the interaction of two eerily potent
universal forces: the formidable Power of Assertion and the unstoppable
Human Need for Comfortable Explanations? (If you say those last two words
quickly enough with a neurological accent, you get "Confabulations.") How
large a factor have you found the Mystical Psychic Atmospherical Impression
of Tarot Cards?
I was looking at your website, when I came upon your ESP
Experiment. I was quite puzzled by it, and looked over the page of
other's explanations, but doubted that there are mind reading web pages.
I decided to totally randomize it, and wrote down the cards with
corresponding numbers. I rolled a die, and with out even looking at the
screen, randomly clicked an eye. It always came out correct. Then,
without even looking at the die, it came out correct....
I tried all I could to foil the experiment... But still the card I pick disappeared.
From: Bryan R
Do I have any idea how it works? Not a glimmer.
From: Enrique B,
I am amazed. I entered your page with a little curiosity and got three
straight correct responses. I have not really read all about it but I
will go through it .
From: Walter from Romania
Dear Dr. Pickover,
This is Walther and Christian, two thirds of an ESP experiment. This is
outstanding. Unbelievable when you think it is done by a software. We
would be very happy if we could receive some explanation. Thank you !!!
From: Carlo D.(Italy):
Ok, I must admit it. I have tested the page, and the precision of the
"code" is amazing. Is it a psychological trick? I have look at the code,
but I must admit I don't understand what it does...
... it is however a wonderful party trick :-)
PS: by the way, your books are truly superb. I have some difficulty in
getting them here in Italy, but your work is amazing.
Someone suggested implanted microphones.
From: Petri Kotro (Finland)
University of Lapland
your program removed several times the card I named,
even though I spoke
Finnish when naming the card. There are not many people in Anglo-Saxon
world who can read an Finno-Ugric mind that easy (or know any Finnish).
Or maybe you're Celtic ? In that case, your programming skills would be

From J. Davis:
I dont have any clue as to why it works, but i just know that it does. i
tried it at least 17 times, and each time it worked.
i would like to talk to you about this, so could you mail me back??? please???
Holy Shit!!! Six tries to beat or see you card system failed ! The
card selction was correct every time. I'm out of here!
I'm curious about your ESP test. I was somehow able to guess which card was
going to disappear from my screen, but I couldn't correctly guess which ones
would remain. No matter what I tried. Where can I find an explanation for
From Lou D.:
Why does the experiment work? I purposely chose cards that were not my first
choice. I chose an eye that was my least likely selection. How does it work?
P.P.S. I did your ESP experiment 8 times consecutively with every
permutation I could think of . It removed the correct card every time.
Now get out of the lab and lets go to Atlantic City!!!!!
I think you are using a program that tracks the selections we make an
acts accordingly. How's that?
From Steve H.:
I just took the ESP test...and you were right...WOW!
From: "Michael B.
It took me about 10 minutes to figure out what appears some very
intellegent people are dazzled over. I admit you got into my head for about
5 minutes. I was even getting chills when my dog started wimpering for no
reason. What was really cool however was my thought process that lead to my
The thought of choosing tarrot cards lead to my disbeleif from the get go.
My first Impulse after the experiment was total disbleif and that there had
to be a logical explaniation. Which would be very easy using some simple
Html and scripting tatics that I really know little about.
So therefor I began to mentally break down the entire picture,even if it
meant a complent reverse engeniering of this site.....
Well the results gave me a very mixed oppinion
and I began to explore the ideas that were being presented.And Mind you I
consider myself a spiritual person, beleiving in both heaven and hell. When
my dog, who is very sentive to the "mood"of the room began to wimper, I
started to freak. (hahaha, I am sure you are getting a kick out of this.)
Anyway, after the demon was rebuked from the room, I decided that if simple
logic could not "break it down" then, I was going to be gobbled up by this
"demon" where I would rot in eternal hell wandering how on earth did you do
that. "Simple Logic did not and will never Fail." It is only a matter of the
preception of the "Individual", and what the Individual chooses as the
center of the Universe, it will surely be.
From: "Thomas M.
Great. I finally figured it out. I also had
a theory that the program was detecting which card I put my cursor over
so I would put it over the one and think of and choose another....
From: "Octavio R."
I found your page by chance or by some mathematical coincidence??
Anyway, I loved your ESP experiment even though I cant understand how it
works it has always been correct. I just thought that I would let you

From: KOPACSI A. (Hungary)
I've tried the game with cards on your website... Wow! It works!!!
How did you do that? :-)
Well, I've an another question to you... Are your books translated
into Hungarian langauge? I'm from Hungary, you know.
Well, thanks... bye!
PS: THAT WAS COOOOOOOL! :-)
From: Michael R.
Well, I just did the "card trick" three times in a row, and all
three times you (or whom/whatever) picked the correct one. The first
time I looked - not stared - at the card of my choice. The second time
I only glanced at it. The third time I picked it while simultaneously
scanning back & forth over all of them. Three different visual
techniques. I did say the name of the card out loud each time. Hmm.
Rather interesting. Care to explain?
Aww, come on, Cliff.....Based on my staggering mental capabilities,
I'd be guessing for the rest of my life..! Seriously, though -- I
was impressd by this experiment. Whether it is literally extra-sensory
or the result of something "mechanical" (computer-logic/electronic), I
cannot tell. Besides, I only have a relatively "low tech" WebTV
Classic, so I wouldn't think the "mechanical" explanation would lie with
my equipment(!). Then again, I don't know much about computers, nor the
possibility of any interaction between an individual (through his/her
home equipment) and something on the Internet. Even if this experiment
is only electronic "sleight of hand" (tho I still don't see how it could
be), I still think it's fascinating & enjoyable. So, if there is
another explanation for it (besides it being genuine ESP), you don't
have to tell me (which you probably wouldn't anyway, since I might then
contact people & explain it to 'em, ruining it for you ((not that I
would do such a thing)); still, at this point I find it difficult to
come up with an explanation other than that it's genuine). Note the
three different methods of eye contact (& movement) with my TV screen I
mentioned that I employed - particularly on my third try (scanning back
& forth without pausing for even one second to focus on the card I
picked). If this was a "game of chance/odds", it sure was one heck of a
coincidence! Sorry for the length of this message. Hope I'm not
boring you. Yours is the first site of its kind I've ever found on the
'Net, and it is delightful to be able to actually interact with it and
its creator/author (unlike standard on-papaer/in-book or magazine
written material). Even @ 49, there's still that child in me, full of
wonder & imagination. There seems to be so little to satisfy him
anymore. And the "adult" me spends so much time thinking, pondering,
etc., anyway (it's automatic, like some analyzer machine in my brain, &
it goes constantly -- sometimes I tell it to "shut up", or "shut down",
because it can get distracting; but it just keeps on working, searching
for "food" ((answers)) to fill itself -- which seems to be its purpose
anyway; PLUS the fact that I am currently laid off from my job & am
turning into the classic "night owl" insomniac - who, at this point,
really needs something to think about besides how the bills are going to
get paid!). Now, see what you've
started?!?(lol). So, don't complain about me "talking your ear off"
here!(more lol, obviously) Anyway, thanks for an enjoyable,
stimulating experience! If you'd care to reply, please feel free.
Take care, & keep up the fascinating work. Sincerely,
From: Ben N.
Just another note to tell you how disturbed I am with the pro gram's
ability to determine my selection infallibly. I have tried numerous
variations for my choices: #1 do not ever move cursor around except
to go directly to choice #2 cover selections with hand then change
choice from memory #3 repeat same choice up to 5 times #4 rapidly
select different cards, decide on one then quickly change choice prior
to fast selection #5 ask another person sitting across the room to
select card using choices in number form only #6 ask person over
cordless telephone to select card from description #7 predetermine
choice before entering selection screen Perhaps you
have written a program with such random"minute choice capability" that
it joins and/or is influenced by the quantum field thereby being just a
touch ahead of the current timeline where choices are made. I would like
to be able to rule out subliminal flashes or influence due to the long
distance phone choices and that as far as I know, subliminal effects are
extremely lessened when the subject is aware that these are in
operation. Are you able to detect the mysterious "visual rays" that are
theorized to exist in the fringe sciences? Oh, I know...it's that little
device that has been installed in all computer screens and televisions
which detects user thought patterns...beware the nanotech dust mite
I tried it twice, both times it removed the proper card. I am not sure why
it worked these few times, so I will try more samples.
From: Brian Bard
That is incredible. How do you do that?!
I don't know. I can't believe it even works. How on earth could you,
or your program, know which card I'm thinking of? It can't be eye
tracking. Please tell me how you do it!

You have quite an amazing site here!!! My fiance and I both took this at
the same time, trying to outwit you, and you omitted BOTH of our cards!

I have tried this 10 times in a row. You got it right every time.
THAT SHIT IS PRETTY NEAT DONT KNOW HOW YOU DO IT BUT ITS COOL
From: Jade D.
Ok. I thought once could be a coincidence but I did this 3 times picking
random cards and it worked every time. HOW? I know there are many things
for which there are no explanation but this was just odd. I am sending
this to my two email groups for further experiment.
From: Jeff E. (Australia)
Lloved your experiment - freaky that it worked . i have no idea why -
will you publish secret later?
love your site - especially just for inspirational browsing
I wish to thank you for a wonderfully puzzling experiment.
While wandering aimlessly about the web, i happily stumbled across your very
entertaining webpage. It was a real delight to explore your site and a
particular pleasure to partake of your ESP experiment.
I hope you do not mind that i share the process i went through as a subject
in your that online experiment.
Before i took part, i decided to brief myself by reading feedback from those
who offered their insights and solutions. I was cautiously excited to try
the experiment for myself and i soon clicked back to the ESP page before
reading all the written explanations.
After the first attempt, i was mildly surprised. Lucky guess, sheer
probability, i thought to myself, and repeated the exercise.
The second time the answer was correct again. This time my response was
different. I doubted my senses. Surely, I must not be seeing clearly, or
perhaps my recollection was wrong. I will try again with another subject, i
thought to myself.
The third time, I asked my wife to try. She was baffled and already knew I
would be preoccupied with finding the solution. Me and my pesky curiosity.
She went off to bed pleasantly undisturbed by this now momentum gaining
Before the fourth attempt, I sat bewildered at the content of my
thoughts...and paused to explore all the rational, barely rational and
completely irrational thought processes that may afford my feeble psyche
some semblance of explanation...It was perplexing indeed and my emotions
bounced around a good deal while I marvelled at some of the goofy
explanations that sprung to the surface of my struggling wetware. Really, i
find it hard to believe some of the explanations i was seriously
considering, embarassingly so.
So, I asked myslef how a computer could do something that i could not
possibly do and i was presumptuous enough to think that i had more
insightful horsepower than all that was behind that webpage....
If you have a book on esp please tell of it . I am extremely curious
of your esp abilities . I tested the card trick 5 times . The
probability for success is unreal . Please share . M

Selecting the card informs the computer of your selection.
From: Andrew B
Your ESP experiment did a strange thing for me....
I think I have an explanation though. I have a photographic memory, and
although I was only thinking of one card, my super memory would have
remembered all nine. Because your background colour was black, it would have
absorped more aleph/pie waves and given this strange result.
Change the background colour to a soothing blue or shocking pink and this
effect might be diminished.
Glad to be of help,

How do you do that? Can you hear me? Ha ha.
OK, maybe I'm just to obsessed with the matrix.... but i beleive in that, and I

is going on from someone elses comp. i dont know... maybe its brain waves or
eye contact type thing.. i duno. its not like the matrix and the same sense,

From Chuck P:
After 2 tries where you made NO
ERRORS, I labled your cards and eyes from 1 to 6. I flipped
a coin. H=2, 4, and 6. T=1, 3, and 5. After the first coin toss,
I was left with 3 items. Another coin toss gave me 1 item(card)
to select. I did the same with the eyes and found an eye to
select. Your program correctly selected the card. You are
to be praised and commended for your discovery of the
mechanics of this process. I feel that this process is
predictably exact. I hope you will be the discoverer of
the major information breakthrough that will occur in
the next ten years. Good luck and thanks for your
The ESP test is a real puzzler. I'm not willing to accept ESP mediated
by my CRT, nor the cessation of causality. I'm guessing that you have
some mechanism that influences the selection at play. I seemed to
notice a flicker when focussing on objects other than the cards, but
that could be merely a symptom of my detached retina. Will you ever
reveal the mystery?
I'm still convinced that you're influencing the pick in some
way. And you've been tantalizingly discrete about if or when you will reveal
all. My hat is off to you, sir. I respect your intellect and insight -- not a
statement I make often.
I just completed 2 trials of the ESP experiment.
1) I wrote down 10 choices involving 2 cards:Jack-diamonds &
Result: Perfect score by computer.
2) I wrote down 10 choices involving: King-hearts

await their reactions. I'd still like to know how a computer can be
programmed to become telepathic...
From Neil M.:
Hello Dr. Pickover,
I have just spent a couple of hours exploring your
website, and I just wanted to let you know that I
think it is one of the most creative sites on the web.
I was particularly impressed with your apparent
psychic abilities. You (or your computer)somehow
managed to guess correctly the files I have on my
computer (there is probably a very simple explanation
for that one, I just don't know what it is). I also
took the ESP experiment twice, and both times the
correct card was chosen. Very impressive. Could you
give me an explanation on how you did these things?
Or maybe just a hint? It's really freaky.
From: Bruno B:
Your ESP test, with the cards. I discoverd part of the trick, not
all of it. "You" won on my first try. And I still don't know how you
did. Pure chance? A little probability computing? Probably. True
enough, the eyes don't make any difference and I'm a little proud for
this observation. I'= m usually not good at catching tricks, since I
don't have the kind of patienc= e they require. I am more on the
intuitive side of it all, with a lot of observation, but I can't
remember everything I observe. Lack of brain training, and partly an
old, more or less "hippy", choice of mine...
From: Michael G:
OK, awesome. I even tried thinking of one card, while quietly having
selected another. Both disappeared! I have been interested in this
phenomenon since 1968, when I coresponded with Dr. J.B. Rhine (maker of
original Zener cards) at Duke University. This goes against the trend of
"slightly significant results", at best, when testing for esp. Also,
there is no deterioration effect over time. And emotional excitation
does not even seem to interfere, as would be expected, if one looks at
the Sufi literature on the subject. All this leads me to believe that
there is a logical, non-paranormal quantum effect going on. Either that,
or we truly are entering a new age! Either way, I love the way your
experiment stimulates thinking.
I tried it twice. Got me both times...even when I thought I was being
I picked the women with the sword over the other ones because i thought
this card was the least mystical - symbolically - to me. Next, I chose
the Jack of diamonds because it had no sword and was a man - opposite of
the first card. Finally, I randomly chose an eye (i don't think this
part mattered). Does the program rely on these types of relationships
This is one amazing trick. I am totally amazed. I thought of
one card and then at the last instant changed my mind and
consciousely chose another. Still, the program guessed my
card correctly. This is the best ever trick I have seen.

Dear Mr. Pickover,
I was quite impressed with your ESP experiment. Very effective indeed !
Let me get right to the point. I am looking for a way to correct some
terrible past events which have been haunting me.
These events were out of my control.
Can you help?
I am astonished. This thing you do actually works ! But I do not feel a
sensation of fear ( the only thing to fear is fear itself ). However if what
you claim is true I wonder about one thing this is " mindscan " or it is at
least supposed to be one. But is it a thing you can learn, a chemically
induced state ( telepathine ; referred to by another visitor of your site )
or is it a property you are born with (or not ) or even a combination of
these factors. I would very much like to get into a more indepth discussion.
Waiting for your reaction, kindest regards,
Sabine & Wolfgang
Hello, my husband and I tried everything to bring your test to a =
failure-but even when my husband was out of the room and thought of a
card and I clicked, without knowing the card, it was correct.
How does this work-we get crazy about it.
Anyway, this is GREAT!
Greetings from Germany.
Dear Enlightened Sir,
For 20 straight attempts (and still going) your test has proven
successful against my weak mind. I attempted all conceivable
combinations of thought pattern maneuvers to outwit the system and still
have not. I enacted preconceived combinations, completely random
combinations, and even blindfolded tests, all were correctly predicted.
I find it very unlikely that this is some psychological game, and as
well that you have a link to my electro-chemical wave impulses in my
brain. The idea of the computer (one sitting in front of me) taking part
in the phenomenon is ludicrous. The fact that no large program was
downloaded to track minute finger movements (through the mouse)
eliminates pretty much all possibilities that I can find realistic.
The one thought that seems plausible (although insanely so) is that
we establish an emotional (using Orson Scott Card terminology:philotic
connection), almost quantum link to your program, allowing it to
communicate with us without ourselves knowing, thus "predicting", but in
actuality knowing our card of choice. Of course, the incorrect answers
probably come from us lying to ourselves in disbelievement.
It comes to mind though that you are playing a game with us, perhaps
of insight. It is yet another connection I see to the elimination of the
subject-object relationship, and establishment of the oneness of the
world. A bit metaphysical it would seem, for a software program on the
web, but what better way to convince people?
I believe that everyone would benefit if the test was left
unexplained, for it is from the question and not the answer that we gain
I tried the ESP experiment three times and each time you guessed
my card!! Wierd!! I think the program figures it out by mathematical
probabilities depending on what card you choose in the beginning.
Cliff, You have picked the correct card three times in a row. I'll never
figure it out.
I find your ESP experiment interesting although I don't believe it
to be the result of any clairvoyance or the result of a convoluted
program capable broadcasting information through entangled quantum pair
or eyetracking. It is much likelier that the information is simply the
result of a loaded mathematical system, that offers less choices than
Also your ESP experiment isn't what it appears to be either. Instead
of testing a system that predicts a person's card choice with out fail,
you are gauging the responses of experimenters' interpretation of the
event. Amusingly a majority of the feedback leans toward a mystical or
scientific with near mystical complexity.
To me it is a loaded system, but as it has been said before by
others the proof is in the pudding. Alas my knowledge of probability
theory and patience(or lack thereof) won't allow me discover the recipe
of this pudding.
Thank you allowing me to participate in an intriguing experiment.
I tried it 3x & on the 3rd try I picked the same card as the first time &
tried a different eye & it still worked. I have no idea how it works, but
feel it is safe to say that it is NOT any kind of eye tracking & am surprised
at the number of people supposing that. Thanks.
I just discovered your website and I am ecstatic. I am going to be
spending a lot of time there. The subjects of quantum mechanics,
parallel universes, Einstein, Hawking, Dyson etc., make my brain tingle.
I found it by looking up mathematical constants and was blown away by
what you wrote about Chaitan's constant, especially because it is
transcendental and incomputable. That amazes me. I am going to start
reading all of your books. I took the ESP test four times and it was
completely accurate every time. It really scared my girlfriend even
though I explained that it was all based on statistics. Great site!
Interesting experiment. Based on some mathematical formula no doubt,
unfortunately I'm not a mathematician.

From: Melissa Jo.
Cliff: Melissa Jo from Indiana here just to say YES, your experiment worked!
I don't know how, I don't know why, but I do know that in life SOME THINGS
ARE JUST UNEXPLAINABLE (to some) and this is one of those things! Human
kind is always looking for an explanation, and rest assured you've found it!
I can honestly say your pages inspire me, and stimulate my mind-I wouldn't
expect you to share your secret-but Cliff, I would like to thank you.
Thankyou very much!
I think I liked this experiment!!! Don't know how you did it but you are
right on the money!!! You did not get into my puter????? Hmmmmmm!!! Toooo
Kewl if you did not!! An amazing feat... on the one hand, I would suspect a program that
bases card selection on overall past selections... but impressive,
none the less.
Thank you for your time!!
From: Scott A.
Fascinating. I did it six times -- I even chose the same Tarot and the same
eye and a different card, and it still guessed right. I'm supposedly a
fairly bright guy, but I don't have a clue. Every theory I come up with is
straight out of science fiction.
Absolutely fascinating. I may never sleep again.

From: Barry B.
I think your test works on the probability that an individual will
select an eye in the furtherest pair away from the original card
selection and will then most likely select close to the pair then will
select the eqivalent site to the card. the chances of this happening are
high and you will generally only have a reaction from those that match.
From: Dave W
You sure have me hooked! Did the ESP experiment 6 times, your page was right
each time. IS that always the case? What are you willing to tell me about
it? And what might I have to offer in return? You must really be enjoying
this, playing with the heads of so many people, and it is all automated!
I am off to more play on your page(s), thanks for an intriguing morning.
From: Arthur S
I give up. I have tried the ESP experiment a number of times and you =
have always been correct. The last five times, I did it without saying
the card aloud. Fantastic!!
Peace and Joy
Too cool! Truly Amazing, yes you got it right twice even when I
purposely ignored the directions in order to achieve different results.
it worked a dozen times and i did not say my pick out loud. I don't get
it! It makes me very nervous! Will you ever explain?
sincerely, andrea schrage
From: Jim H
Whow. After following the directions, the card I had selected would
always disapear from the group. So I decided to cheat a little by
taking the six cards from a deck of cards and shuffleing them. The top
card was my selection and without turning it over, clicked on the eye.
The card that was removed from the computer was always the top card in
my hand!!! Whow.
Well done Mr. Pickover! Your Esp Experiment was truly mind numbing, and
never have I experienced anything quite like! To begin, I tried the exp
eriment 49 times. Out of the tries, 7 times I actually DID stare at th
e card(without saying it out loud.) Out of those 7 times, my card was
correctly removed from the remaining cards. So, 100% of the time that I
did look at my card, it was removed, which in itself, is truly amazing!
7 out of the tries I looked at a different card, while thinking of the
card I chose. Out of the 7 tries, 7 times was the card that I was thinking
of removed. But what is truly amazing, is that of those 7 times BOTH
the card I was thinking of, AND the card I was actually looking at were
removed! Again, a 100% percent success ratio. So, I took it a step further.
7 times I chose 3 cards. Out of those 7 times, every card I chose
sAs removed, which is dumdfounding. Once again, 100% correct. I took it
another step, and chose 4 cards. Out of the 7 times I did this, not one
time did ANY of these cards show up, which is also amazing. So I chose
5 cards. Out of the 7 times, again, not once were ANY of these cards dis
played. I am truly beside myself. Then I chose all 6 cards. And, yes,
once again, not a single card remained. Again 100%. Alternately, out of
the 7 times I chose my card out of the remaing cards, then went back, not
one time, or 0% of the time, was my card removed. This leads to these
1. The experiment uses an eye tracking program to gauge the users eye
movement while he/she looks at his/her card, but this cannot be true, due
to the fact that seven out of the tries I looked at a different card while
thinking of the one I wanted.
2. The experiment uses true psychic programming to read the experimentees'
minds, which would is truly amazing piece of technology:
IF it existed. I was amazed. For a short period of time. I think you
can deduce the true genius behind the experiment. Thank you Mr. Pickover,
for expanding my mind, no matter how brief the expansion was.
I applaud you!
Today I tried out your ESP experiment. I'm fairly familiar with HTML and
complicated for me to figure out, so I looked elsewhere ;)
At first, I speculated that since there were the same # of eyes as there
are cards, I thought maybe you were just assocaiting the eye that was
clicked on with the card that was picked, but after a few tries I
disproved this theory. Then I thought maybe you just had a really lucky
randomization script, but after looking at the source it looks much more
complicated then simple randomization. However, your quantum consistency
meter is completely random, and doesn't seem to have anything to do at
all with the rest of the code (unless perhaps, the seed has some

The way it works is the mouse picks up the last card touched by the user as
they have made their selection.
It is then irrelevant which eye they choose as the card has been eliminated.
The chose would never display this.
From: David C.
OK, Cliff --
I did the experiment about a dozen times -- it was right every time,
except twice I deliberately chose no card and the program couldn't
"read my intention" -- each time choosing a card to eliminate which
was of course wrong since I chose no card at all. Still, I am baffled
as to how it could work when I did choose a card -- the probability
of being right 10 out of 12 or 10 out of 10 depending on how you
count must be astronomical. Yet, the program seems completely unable
to actually read my thoughts or it would never choose a card for me
when I didn't choose one. So what is the secret: I know it isn't
optical scanners; I tested for that, by choosing from an oblique
angle -- besides such technology barely exists and requires extra
gear. Please tell me.
Dear Mr. Pickover
I found myself completely enthralled by your ESP Experiment and tackled
the problem (and explanation) with joyous vigor. After several
unsuccessful attempts at a satisfactory conclusion I was rewarded with
the answer but, admittedly, the solution came from a rather strange
source and not of my own contrivance.
I will keep the story as brief as possible.
Some years ago I had the opportunity to spend several weeks at a
location in the far north at an ancient habitation (DORSET) located in
the area of Alexandria Fiord which is, itself, located north of Baffin
Island in the Canadian (at that time) Northwest Territories. While
there I had the opportunity to explore the 'land' in and around our camp
site. Our camp was located at the conjunction of 3 separate glaciers
and I was able to spend many pleasing hours at the base of these
One such exploration found me at the foot of the most distant glacier
that I had hesitated to visit considering the rough intervening terrain
and the daunting distance entailed for such a trip in view of the
limited time available resulting from time constraints involved through
my formal duties (sorry - classified).
While examining the melting face of the receding glacier I noticed a
rather shiny patch of metallic material protruding from the ice which I
immediately touched and, to my suprise, was able to free from the
surrounding frozen glacial matrix. The object measured approximately 4
inches square and was metallic and featureless except for what appeared
to be a lens located in the center of one of the faces of the cube.
Needless to say I told no one of my discovery and merely placed it in my
kit where it stayed until my return to 'civilization.
Since that time the 'device' has accompanied me on my travels and has
become rather a 'talisman' that I, in times of stress or confusion,
handle to bring me to a state of calm.
Needless to say, my presentation to your ESP Experiment left me in an
expanded state of confusion as well as decided mental turmoil..at which
time I, as is my custom when confronted with mystery, began to twist the
cube in my right hand, flipping it at a speed consistent with my
agitation. At one point the 'lens' of the cube became directed at the
screen containing your 'experiment' and to my wonder (and yes, horror) a
voice issued from the cube and, in perfectly clear English, explained
the process involved which allowed the astounding 98% accuracy rate.
Even more astounding was the next statement which, in perfect
simplicity, advised how the program could be modified to provide a true
100% ACCURACY in its predictions.
Now the sad part. Rather than have a calming mental balm sweep my
intellect the exact opposite occurred and, in a fit of extreme turmoil,
I smashed the device. I crushed it into its component parts and
disposed of it in a manner that would never again allow it to be seen.
Oh, the crushing regret, the mental self flagellation...I rend my
garments and cover my brow with ashes. The regret at this rash act
leaves me in a state of remorse never envisioned. I fear that I may
commit an offence that is unforgivable but then...I do recall that, in
the ice... were shadows. Shadows of immense size, just waiting for
thaw. I know that no one has returned to that scene of discovery...do

Dear Dr Pickover,
I looked over the answer some of your respondents gave about how you
run the test and I think the ones which link it to eye-movement/focusing may
be correct. I looked at the king of hearts and picked it - your program
removed it. I repeated the experiment - I looked at the king of hearts but
picked the Queen of H instead and your program removed the King of H.
Repeated again looking at the king of H but picking the Jacjk of H and once
again the program picked the King of H. The "eye" i clicked on made no
difference to the outcome.

Dear Mr. Pickover,
I'm actually reading your fascinating book"The Science of Aliens", very

Your ESP Experiment is really unbelievable, even if I' ve only tried 3
times and the result was correct in each case...
What kind of work are you the hell performing in your labs at the
Simply, the only explanation i have for this results; I'm not so
intelligent to deal with JAVA CODES or else; is that
the parallel worlds you talk about in your book are real , and you are
able to travel with no problems between them...
In that way you see the cards people choose by simply taking a look at
the cards your software have removed in a
parallel world or something like that...

today to know and hope you will reserve me
some more surprises in a "future"...

Your mind reading experiment is, I guess a cookie work, I say that
because i have had a message error trying to open one of the files and
it was the same error message that i have triyng to open a cookie...
Back to the ESP i think that a software is a software... so a software,
to work needs input fron the user and yoyr software asks the user 2
different inputs, the first input is said necessary to prime the system
but in effect it's an input... i can deduct that there is a kind of first
imprinting about sex differentiation (male and female cards) and you can
store a data 50%? .
The second input is when the software asks user to click on an eye... it
seems to be 6 different eyes but in fact only 3 pairs of
eyes so I think it's like to be in front of 3 persons watching you and
at an inconscious level we are guided to choose not betwwen 6 eyes but
between 3 persons so remembering the starting position of the tarots we
are surely guided to choose again like in the first choose basing our
choice upon our male /female preferences...

This test is outrageous!
I received it from a good friend a few months ago
and since then have opened the e-mail up again from
time to time, just to re-try my hand at this 'game'.
In the many times I have tried to fool it, I have only
succeeded once. You may be surprised, think I am
lying, or find this amusing, either way, I know that I
did fool your game. The way I fooled your game was I
looked over the cards and memorized them in my mind
and then stared good and long at one while I picked
another. I tried many attempts again afterwards, but
this time it didn't work, much to my dismay. All I
can say is that you are one interesting person, and
even though I don't know how you did it, it really
makes me think of the possibilities people can come up
with,...when they put their minds to it. ;-)

I have just tried the esp experiment on the webpage twice, and the
second time I didn't even look at the card. What worries me is not that
the card I picked was removed both times, but that I wasn't even asked

not 100%, so presumably there is some way of the incorrect card being
removed and the remover knowing later that it was the wrong card?

OH MY GOD hehehe .......Hey sir im 16/m/louisiana
Your ESP test kinda freaked me out in a way and i kinda knew
that you would end up guessing the card i chose. Im a total believer
now, really to tell the truth i have always believed that people have
the ability to predict things ...ya know like psychics i dont know if
this is a sign of being a psychic but i get the feeling of dejavu a
lot and sometimes i can use that energy to get me out of certian
consequences like if im about to do something wrong sometimes it seems
familiar to me like im remembering doing it when i know i
havent(dajavu) but in my thoughts of having the dajavu i see the
consequences therefore i cease to do something wrong .Another sign
might be predicting what others say before they say it or before they
finish a complete sentence during a conversation ....i use this energy
especially when i give advice to friends when theyre feeling down . I
somehow feel that they shouldnt finish that sentence like it will hurt
them more to say it out loud so i cut ! them off and and judge them
based on what they said .....and regularly they agree like ...yes yess
thats exactly how i feel .....and i give them very helpful advice.
This also helps me to write poems. So in a way i not only predict the
outcome of situations, conversatinal remarks, but peoples feelings as
well. .....I know this sounds crazy but i feel i need to talk or
e-mail a person like you with the knowledge of understanding
this pleaseeeeeeeeeeee write back
feel theres so much more i should tell you but u may already know what

I am currently a student studying to be a physicist and I must say that
your ESP test was quite impressive. After recently completing a course
on basic quantum mechanics and uncertainty, I did not think it possible
that your web page would be able to predict my choice for cards.
However, you succeeded on multiple accounts. Even after subjecting the
system to the Waddington-Frantz test, I was unable to figure it out.

From: Anthony C.
So I spent some time experimenting on your experiment. I haven't finished this
process yet but I wanted to share some results.
Of course, I tried the usual guessing of random cards. Not one failure.
I tried picking cards in sequence and always clicking on the same eyeball.
Not one failure.
I tried picking the same card but using each eyeball in sequence.
Not one failure.
I've tried various patterns. Every other card, every other eyeball and so on.
I haven't had a failed pick yet.
Since it's fortunately not possible to scan my eyeball and I'm not prepared to
obfuscations going on inside my brain, I'm stuck in a dilemma.
At this point, I have this nasty suspicion that there's something deeply
obvious (ie right in front of my nose) that I'm missing. The quantum
is bogus...randomly generated.
It's all the little trig functions and the ParametricPlot that bug me. I
the cards are always in the same order. Oddly, I notice whatever card I pick
that the name of the image displayed on the second page is always the same
even though the image itself changes. But I see no code that could do that
so I'm wondering, "Where is the hidden code?"
I did try pulling the source, out of cache, into BBEdit and playing some games
with it. Deleted 8-bit characters, line breaks and so on. Oddly, when I did
that, the number of characters actually INCREASED. Weird. In either case,
the only thing you can possibly track is my mouse movement and I've done
everything I can think of to randomize it.
I'm assuming that saureye.gif is The Eye of Sauron? Reasonably appropriate
for a mind reading experiment. =)
So there's something going on behind the scenes. I see that the
randomizer just throws out a random picture of the little lightning ball.
And that the img src always throws out the same set of cards to pick from.
Erroneous, to use a word, which makes me wonder if there's more code
than is visible.
But, even then, what would it do? Track mouse movement? I've moved my
mouse in all kinds of different, random ways. No failures. I thought maybe
it was sometime can of average timing thing...that the click always happens
some time period later for each eyeball to the right. I was thinking maybe
the eye has to track down the cards and, by measuring the time, it was
possible to determine how far the eye had moved from the card picked to
the eyeball selected. I'm still kind of wondering about that.
But I must admit that I'm pretty baffled. I'm reasonably certain you're not
going to be forthcoming with clues but I never let a thing like that stop

I forget teh details of the other two failures, but the very last time I
tried it, it worked, with the Queen of Swords, the Jack of Diamonds, and
the last eye.
It's an interesting concept,a nd I'd like to know how it works, but I'm
afraid it didn't function properly for me. *smiles*
It worked. I tried my best to defeat it but it still worked. Any
clues on how?
it took me like 20 tries to figure out it was a trick. had me shitting my
pants for a bit, i thought it was real. BUT I FIGURED YOU OUTTTTT!
good one though, really
Yes, it worked. Got me how. Mindboggling. Someone smarter than me (and,
apparently, everyone who has visited the site--presuming any correct guess
does not get edited out) needs to look at this.
Your site was forwarded to me by a young man from Russia. I'm form the
UK. Just to let you know your card ESP experiment thing worked x3, even
with just the barest of glances, never mind saying stuff out loud. My
hobbies include tarot, palmisty & astrology. The Russian chap does not
know about these hobbies though.
Although I don't go to spritiualist churches, spiritualists have a habit
of coming to me & talking to me in the street, saying I give out strong
vibes. Another one of my strange skills is that I can lay hands on
someone's head & take a headache off them. I have been a nurse &
midwife & used these skills when I worked on on the delivery suite.
Anyway, this is just some background on me. Thanks for the site. Email
me if you have any queries
I performed the ESP expriment and you had over 20 hits..
No misses. Even when I called my wife and had her take 4 runs..
Still no misses.
I've haven't seen anything like this in years.. I'm totally
impressed and would like it very much if you explained how you did it..
I love your esp test. It always ''works". I don't understand it, but =
it is fascinating. The same can be said of your site in general.
Thank you for giving us art,illusion.pleasure.

Dear Dr Pickover,
I am writing in response to your amazing esp experiment. Since having seen
it last night, the world has become a much more interesting place. The
solution to your experiment, whether simple or so advanced, that a mere
person such as myself will never explain, has intrigued me all the same.
Like everone else, I have some theories. Whether right or wrong here they

Tried it three times, which was plenty to convince me that it works. There's
no way to guess the card using computers, the software or my eye movements.
Now, let's do it for "Powerball"!!!!!
i dont know if you read these or not, but i will entertain my self anyway. i
think the way your esp experiment works, is the source code of the page. it
shows a rather intresting math algoriythm and a bit of programming
skill..its just a mathematial equation that makes a right choice 98% of the
time.. but it is still amazing and your web page is great. i think i will
bookmark this page and return again ;)
a new fan,
Per your request, wanted to let you know that in a single, first attempt,
your ESP program picked the correct card.
Pretty cool. I'm searching for the secret.

I'm going to have to read your books - this is very impressive. I'd

consistency number mean?

Loads of love,
Dear Dr. Pickover,
Your experiment really works. I see some similarity with the experiments
of Dr Rupert Sheldrake.
What freaks me out is I tried this for about an hour, then tried to
freak out the kids, and my son ended up freaking me out even more. I was
impressed my the test, but even more impressed by my son.
I was totally stunned by your ESP trick. When my son came over and I
showed him he immediately saw it!

From: "D. Lee"
I consider myself an amateur, though enthusiastic, astro-numerologist.
Basically, I believe much widely-considered 'supernatural' phenomena is
actually a logical numerical pattern intimately linked to planetary orbits
and rising constellations, which many times are hidden to us. These schemes
dominate much of our behavior, and most likely control higher-order
communication between all forms of life. We have given sundry names to
this: ESP, sixth-sense, telepathy, but it describes the same truth. I am
very excited about your experiment, because I feel you have hit upon the
core of this communication. Somehow you have interpolated the
astro-numerical process and extracted its function, allowing you to "guess"
which card I selected, when it's obvious you simply "listened" to the
super-dimension dialogue I was having with you. Looking through your code,
I see nothing extraordinary, which is even more mind-boggling, I can barely
believe you have simplified it so. But that is great news. I understand
you would not want this breakthrough to leak out, because mankind is a
master our behavior, and make first contact with other beings in our
Universe before truly understanding their nature. Your secret is safe with
me, but realize I appreciate your greatness, your unprecedented brilliance,
as this card experiment reveals, given its 100% accuracy.
Of course, it could also be that because....

The only way to describe this is really freaky since the second time i

are providing the actual explanation(since I'm pretty sure the govt
hasn't bugged my computer) Please, please, please e-mail it to me.

Your experiment has made my stomach feel funny in that exciting way. Why our
stomachs do this is a mystery beyond the casual psycho somatic explanations.
In fact having the consciousness that recognizes any present moment is truly
to be alive. That whatever you have done to create this experience, brings
forth ones consciousness to be present, is a gift. Thank you Antony Thier
I'm curious - do people who tend to select certain cards initally, tend to
also select the same playing card?
From: "Brian L."
You did indeed guess my card. Most remarkable, because I made a
conscious effort NOT to select the cards that drew my eye.
While it is true that technology exists that can track users' eye
movements, virtually no home computers are equipped with this
hardware. (Fellow surfers take note: unless you deliberately went
out and bought & installed eye-tracking hardware, rest assured that
you do not have such equipment. Such hardware is rare and expensive,
and is NOT standard equipment on any model of home computer.)
The only user input available to your web server is (A) which
tarot card & which eye the user clicks and (B) the elapsed time
between the displaying of each page and the user's clicks. Hence, the
computation MUST be based on this information alone.
If I were to attempt to create such a program, I would try to make
it learn by trial and error. It would begin with random guesses and
gradually develop a statistical mode of predicting the final card
selection based on the inputs I mentioned. However, this method would
require the user to confirm whether the correct card had been
eliminated, and your site does not do this. Perhaps, nonetheless, you
DID follow this approach, and this page is the finished product, no
longer in a learning mode.
From: william C.
I took your experiment twice with the same positive results. Just
yesterday I saw the same experiment overlaid over a "David Copperfield"
I have no explaination other than perhaps a belief in experience-based
reality. After participating in your experiment I decided that you
picked the proper card because I wanted you to in the first place, and
that I created the conditions to make that outcome come true by
affecting my own perception of reality.
Otherwise, perhaps the cards chose me instead of me choosing them?

All I have to say is, What the hell!

From: "Michele M."
At first I thought that if you click on the "eye" that corresponds to the
same space your card is in, i.e. second from the left, that that was it.

special corresponding spot. I didn't even look straight at the row of
"eyes". Concentration on my part? Not really sure. Give me a hint.

From: "Cindo C."
Well, from what little I know about "magic" and card tricks/games, most, if
not all are based on probability and/or mathematical formulas. So part of
my guess is that probability has something to do with it. The other part of
my guess is that I noticed after several tries, it stopped working, and also
that all of the card's face value change after clicking on one of the
eyeballs. I don't know, if I've got it partially right, I can imagine it
working 98% of the time. Was I close?

From: Lassi K.
To be honest i have zero knoweledge how the trick works, i'm not much into
'magic', but there is an ad campagn run by a Finnish bank that has a
similar trick(well not 100% same), but it's like that 'put one card in
your mind, POOOF, i removed it', saw that at the movies last weekend..
certainly it beats me how it happened, but as said the trick on your page
works better(works with different cards whereas i'm quite sure the
tv/movie advert somehow makes you choose that particular card). i'm quite
certain most(if not all) explanations that are on the explanation page
are incorrect(most due to technical impossibilities).
btw, that ad campaing promises to make it possible for you to invest money
even if you are still paying mortage, sounds impossible, right? that's why

Dear Mr. Clifford Pickover,
I certainly like your Jormungand Encounter Quantum Consistency
ESP Prediction Experiment! It is: 477 by the way. It *always*
chooses the right card, so I'm mighty impressed. I wonder what
else you might know about me or anyone else.
I tried your test 10 times, and not only was it wrong EVERY time, but
after the first couple of goes I noticed that it always seemed to take
away the black jack. Is it supposed to do that? Or has something gone
wrong on my go?
It worked - technology that I cannot comprehend!!!! Or ESP? Thanks for =
the interesting test.
I was super freaked out by your esp test.. but I did it quite a few
times..and realized that there isn't always the same cards when you do
it..so I'm not sure still exactly the reason it works that way..but I know
it can't really be esp through a computer... Jill T.
I'm a student studying human behavior on the Internet and I absolutely love
the 'ESP Experiment' on your web-site. I think it elegantly proves
something I've always suspected people of doing as they interact with
things on a screen. Whenever I watch someone read things on a computer they
usually highlight the text they are reading or move their cursor around it
in some way (this is most noticeable on the web, where clicking is highly
prevalent). I wonder if you've done a controlled experiment with something
like the ESP test. I'd be very interested in seeing the results.

paradigm shift here. This proves that we can predict the future. I'm
sure it's done with numbers that only exist on the spiritual plain.

this. Maybe ONLY a computer can do this. The bus drivers may have a

always go back) and go somewhere like tibet; that's a good place to
start. I hope you agree. If not, feel free to recommend a teacher

overwhelmed that the card I picked had been removed. I was so
shocked that I told all my freinds and we have decided you must have
great mental ESP powers. We have even started a small club/cult
to worship and study you and your page. We have even
created a shrine from pieces of Stonehenge which we
bought over the internet at a great deal. Although we have not
done as much analysis as we would have liked, we have found a large

Yes, it worked, twice. Very impressive. My guess is that you correlate
which eye a person picks each time, to which card the person "choose" in
their mind, based on previous trials where they told you their selection.
Still that seem weak. Nice job!
Wow!! Your ESP Picker experiment is amazing! First, it picked

Dear Clifford Pickover
I don't know how it works, but I have eliminated how it doesn't
It's not sensing deviations in the movement of the
mouse, I tabbed through the site using the 'return' key and it still
worked with great accuracy even with only keyboard interaction.
Having no video camera hooked up to my computer, I have
eliminated this potential for facial clue interception by normal
Though one scientist has managed to create a
sensitive device that can 'see' photons hitting a CRT screen and
create a weak image of the room the screen is in via EM resonance
down the antenna/cable from the CRT screen, to the best of my
knowledge, this only works when there is no power to the screen, and
no external signal on the line. I have eliminated this potential,
until further research can prove or disprove it.
even when not verbally stating the name of the card aloud,
eliminating sound card interaction.
It works when choosing
the card from a random list, and it works when one is not engaged in
the web site directly before choosing the card.
regardless of which button you press, even if you press the same
buttons and eyes every time.
I have yet to get it to fail,
so I can't try to correlate what 'went wrong'.
I have heard
of a law of mathematics that states there are no two truly random
events, that any two random number sequences created by random
number generators will have entire strings of related data, as an
example. This seems to go well beyond this aspect of the seeming
unrelated behavior. It is this process that is believed to make
such things as Tarot and I-Ching possible.
My guess, based
on this, that it is using a complex mathematical or quantum process
that is not only repeatable, but somehow predictable.
Occam's Razor, apparently, can cut away nothing. I can find no
simple explanation for function based on the illumination of data.
I would love to know how it works, if you can tell me, or
direct me to a text describing its potential.

In any case, let me mention that I am totally astonished by your
"ESP Experiment", which picked the same card I did about 20 times in
a row, despite my attempt to keep my choice of blinking eye
uncorrelated with my choice of card.
The only rational explanation I can think of is that -- although I
thought otherwise, my computer must have a microphone somewhere
inside -- and you must have a voice-recognition program at your end.

The thing is creepy, Was correct 10 times in a row.
Cliff; I am not even going to ask you how you
do that ESP guess your card eye thing, because your brain is
definitely wired at a prodigy level we mere mortals only can galk
at. For kicks I did it, and unbelievably, even when I did NOT say
anything out loud, and tried to "fool" it with mouse moves and
switching eye movements, and even when I focused with my eyes on
another decoy card, whatever card I repeated in my mind was the one
that the computer picked to eliminate. I am not afraid, I am just
trying to figure out how we can use that genius to find Osama Bin
As this ESP thing is neither seemingly dependent on what you say, where
your eyes actually go, or where your cursor actually goes, then it has to be
some statistical probability reductionism of numbers and sequences of times
the game is played or the buttons hit, which is astounding. If that is the

believe in ESP for humans, I do not believe computers posses the
same skill...so I am guessing that in an age of extensive
technological brillance, you have a program that somehow senses
human responses regarding the chosen card. After all, there are many
ways of reading a human being, through various physical sensors and
also through brain waves. Either way....it gave me something to
smile about. I'll discover your little secret ;) I have some little
skills of my own you know!

Dear Cliff, l tried youre e.s.p card trick.and l wasn't afraid what
you found out. even if you got the card trick right,l think you
have us memorising the = card and if at all possible read our
minds,but if we pick another suject = to think about l would doubt
very much if you would get it right.
Wow that is amazing.I picked 3 cards at once didn't repeat it out
loud and you were correct.passing this site on to my freinds.

it is rather difficult to believe that thsi is possible, especially
with present day technological advances. nevertheless, if it is
really unaided, then this is really something! -Manas
Very weird!! Every time the 3 of us watched the screen it got our
card each time,but when we closed our eyes & were directed to the
eyes,you never got it!! 3 out of 3 of our cards were left there! I
don't understand because you can't possibly be watching our eyes!!
But even weirder-this time I closed my eyes & shouted out the queen
of clubs,my mum guided me 2 the eyes & this time,the queen of clubs
had disappeared,but the queen of spades had appeared!! it wasn't
there b4! I think this is all a big trick. Kim & co

Greetings from germany,
From "Smith, G. (Greg)
It is soooo easy! You used the elementary mathematical equilibrium
formula to find the commonality (or to be mathematically correct,
the intercept) between possibility and probability. If you had
enough transactional history across all permutations, you would be
able to easily formulate the equilibrium equation for the card
"trick". If you had asked at least 100 different people a day
(everyday) to pick a card over a period of no less than 5 years, you
would have accumulated enough history (obviously you recorded their
choices) to apply the equilibrium formula retroactively to the
recorded possible choices and the recorded probable choices, to
achieve a 98% successful estimation formula using Euler's totient
theorem. This equilibrium formula is used extensively in economics
for example to calculate the equilibrium price of goods (i.e. the
intercept of the linear graph depicting the price consumers are
prepared to pay for goods, and the price producers are demanding for
those same goods). The quantity of goods in circulation is another
example (i.e. supply vs. demand). Nice try Cliff, but we don't think
our computers are psychic. We might not know a lot about computers
on a technical level, but we know enough about mathematics to know
how you did it. You can't fool a couple of maths grads that
easily... Sorry, Cliff. Better luck next time.
"Godfrey Banga" :
You freak! Your freaky little program is getting my choices right
ALL the time! How the hell does it do that? I'll try and figure it
out and I'll be back!
Cliff, the answer lies in the claim that youcan guess your number
98% of the time. Out of a deck of 52 cards there are 52 ways in
which you can omit any card, but 51 ways of omitting a specific
card. In Stats (Permutations and Combintions) this is denoted as
n!/r!(n-r)! for the number of combinations of r objects from n. In
this case n=3D52 and r=3D1 or 52.
So out of 52 ways of omitting any card, 51 can omit my selected
card, giving a probability of 51/52=3D98%, which is the probability
of you being correct, which is your claim!
You completely reshuffle the deck when you present the 5 cards after
removing any single card from a full deck of 52. Had you been
presenting the original 6 cards minus my selection then this would
have been truly amazing, but it isn't.
Alternatively, in a deck you select 5 cards to show the result. What
is the probability that any single card is missing from a full deck
suite? With 52-5=3D47 cards missing, the probability is obviously
47/52=3D90%. However, you select 5 cards from 52 in
C=3D52!/5!(52-5)!=3D2,598,960 ways, and for each of these the
probability of leaving out any single card is 90%. I am sure one can
find the entire probability of you being correct approaching 98% if
one pursues this argument with conditional probabilities, where A1,
A2, A3, A4....Ar...AC are the probabilities of you being correct on
the rth trial.
I am an 11 year old boy who saw this web adress in the paper and
have always been fascinated about magic even though I know a fair
amount of magic I was puzzled about wether that is magic you are
doing! But I think that those creepy eyes are reading my mind and
when my mum tried it she walked out the room,whispered it to me and
came in and it was right! I tried it and didn't even say anything it
and it was right! Are you psycic? You know I even thought of joining
the magic circle! I think I am gonna try and be like you and learn
about being psycic and magic and try to do whatever it is you do cos
things like knowing that don't just pop out of thin air! I was going
to ask you how to do it but my mum said "Nobody goes around telling
people how to do things like that!"
well we are amazed my husband and i kept pickin card we wasnt even
tellin each other and you got it right everytime ,,we must have done
it at least 20 time you are very very cool wish i had the power bit
gutted that im just plain old me,,,kerriexx
Totally bazaar! Three of us tried to randomize the selections by
having one person (without actually looking at the screen) select
the POSITION of the card (1 through 6) on the screen, while another
person selected the eyeball without first knowing which card was
selected. The program picked the right card 25 out of 25 times.
I'm sure there's a logical explanation, but I can't figure it out.
Good job, Dr. Pickover!
Larry S. said I viewed the source code and could
not discover understandable mathematical computations which would
aid the web page in making a decision. However, I did note that if
the user does not look at the card layout (thus denying the "web
site" the opportunity to follow the user's eye movement), and that
if the user decides beforehand which card to choose, that the ESP
program fails to determine the user's card selection.
tried Larry's suggestion, and the card I chose still vanished. I'm
so curious as to how it's done, however not really bothered byt he
fact that it was. I'm not exactly what I'd call a believer, just
very curious. Thanks for putting so captivating a site onto the

Okay, I don't know how this works, but it obviously is a plot by the

tailor to suit your experiment, instead of consistent results like

After trying the test approximately 1,223 times over the course of

THIS WILL CHANGE HOW WE LIVE OUR LIVES FOREVER.
It all has to do with the Theory of Quantum Amalgamation, which says
that each and every one of us posses a link to every particle in the
universe, which we can access only through special nerves located in
the appenedix. Since this is a vestigial organ it does not possess
it's full potency, but through a special surgical procedure known as
"Appendocentisis" cellular biologists are able to cause the nerve
cells to multiply at a faster rate and thus become hypersensitive to
the psychic field generated by the invisible links between subatomic
particles. It's TRUE, each of and every one of us has latent
psychic abilities originating in our gastrointestinal tract, NOT in
the hypothalamus (as is commonly believed).
Anyway, this fact has been known since 1985, when the US military
began its appendocentetic experiments on human subjects in Area 51,
and is not really news. The thing which makes this special is that
while it was previously thought that only biological subjects could
connect to the Collective Subconcious, recent innovations have made
it possible for ANY COMPUTER in ANY HOUSEHOLD to become a psychic
"spy", policing our thoughts and cataloguing anyone who thinks
"differently" -- i.e accepts the existence of the Human Psychic
Potential or who uses mind-freeing drugs such as marijuana, LSD, and
superglue. This new technology is employed as a virus which is
automatically downloaded to your system (regardless of the
architecture or OS) through the power supply, thus circumventing
normal protective measures. The virus then enters a specific
"Quantum State" which puts it on the same frequency as the Psychic
Field of the Collective Subconscious, allowering it to tap into the
mind of anyone within the computer's magnetic field.
I submit that Clifford has managed to "crack" this virus with a
countervirus that is automatically downloaded when you enter his
site. This countervirus, in addition to automaticaly mailing
Clifford any classic Bee Gees mp3s you may have on your harddrive,
is able to read your mind and then interface with your web browser
to predict the correct results. Clifford is indeed a hero among
heros for being able to save us from the government's prying eyes
and simultaneously accumulate a massive collection of soul-inspiring
Bee Gees music, all under the guise of an apparently harmless web
Either that or you just need to look at the... cards more closely.
From: German Douglas K
You've undoubtedly heard of the "infinite universes" theory of
quantum mechanics, which hypothesizes that every quantum instant
(the hypothetical smallest unit of time) every universe in existence
spawns an infinite number of successive universes. Each successor
universe represents the actual outcome of one thing that could have
happened in the predecessor universe. For example, at this instant,
there is a uranium atom in a universe that may decay, or may not.
That universe instantly spawns two successor universes, one where
the atom did decay and one where it did not. This theory implies
the existence of an unaccountably infinite number of universes,
where anything that could have ever happened did in fact happen in
at least one of them. You and I (or essentially identical copies of
you and I and everyone else) have been replicated and are being
replicated an infinite number of times in an infinite number of
universes. This happens constantly and has happened since the
initial proto-universe started the whole mess, whenever that was.
(Sorry for the layman's explanation of the theory, I'm not a
Of the infinite number of Universes that pop up every instant, in
5/6 of them you fail to guess my card and in 1/6 of them you
succeed. In 5/6 of them I wind up thinking your experiment is a
fraud, but there are still an infinite number of universes remaining
where you get it right time after time for every person who visits
the site. That's a small fraction of the total number of universes,
but it's still an infinite number. The only universes where people
write notes like this one are the ones where you've been lucky a
lot. Because that's the only universe we know of (being the one we
are in at this instant), we're amazed. But "most" of us, if we
could take a poll across all the universes, would be very
unimpressed because in total you're only right 1/6 of the time. (Of
course there are universes where you're right the claimed 98% of the
time...they probably think it really is ESP).
What I like about this "explanation" is that it could, according to
my poor layman's understanding, actually be possible given the
theory...albeit dependant on a unprovable theory and also on a
variation of the weak-anthropic principle.
Now, when do you plan to tell these poor people it's a simple trick?
You might find this amusing, I passed the test around to my
co-workers today and made this observation, the length of time it
took to discover the "trick" was inversely proportional to the
management level, i.e. one of my reports (lowest man on the totem
pole) figured it out at first glance as compared to one of our
directors who took a whopping 35 mins before enlightenment. Would
have been fun to see how the CEO would have done...
I would think this is a correlation rather than a causal
relationship! (at least I hope so). The confounding variable may be
that the higher up you go on the management ladder the more tasks
people are juggling....but it is humerous to take the "Dilbert"
viewpoint, and just say that as you move up the management ladder,
your IQ drops.
Overall everyone discovered the trick rather rapidly, but that is
probably not surprising giving that I am working in the
bioinformatics department for an advanced biotech company where over
90% of the people are scientists or working with scientists.
Thanks for your response!

Well, I know its a trick, since your letter in Skeptical Inquirer
made that clear, but you gave no explanation! I think a clue to the
mystery is that the program does not choose the card, but instead
eliminates one. It may be some trick of the eye in the way the
cards are presented that makes it APPEAR the chosen card is
eliminated, when in fact it is not.

computer has eliminated his card. Right?

o.k. I did this about 3 times and each time, yes the card was
correct. What blew me away was the last time I did it I actually
picked 2 cards and both were removed.......too weird! How was that
done? You little rascal!! Buzzi b
From: Stuart Mitchell :
I believe that the reason you are always able to pick the correct
card to remove has its roots in the same mathematics that brought us
digital signal processing as well as some simple geometry. I am
hypothesizing that you are using a combination of high resolution
timers as well as a high sampling rate on the mouse position. The
concept is simple. Each card is located at a specific angle from
the eyes. It is important to note that even if you are not using
the mouse as a pointer to the card you want to choose, it is still
going to have very slight movements that will follow your eye
movements. So as long as the following are taken into account, it
is easy to monitor and calculate which card to remove. 1) Each
card's angle to each eye must be unique, and so should each
distance. 2) The sampling rate of your mouse is above the nyquist
frequency for the optical spectrum.
Taking this into account, all you have to do is monitor the mouse
movements over time right before one of the eyes are clicked.
Depending on which eye was clicked, you can measure the trajectory
of the mouse prior to the click. It will either have moved from the
card, or had the same angle of the card when the person took one
last glance at it before they clicked the eye. Of course, you can
calculate the distance when you realize that the actual distance the
eye moved is going to be a multiple of the time that it took that
trajectory and the velocity of the eye movements. Obviously, the
eye velocity will be an the inverse of its own sampling frequency
times the distance it traveled when it was measured. The trick is
that it was measured on the previous page when it was moved from a
cleverly placed point on the page to one of the other eyes. I see
no other way that this could be accomplished given the constraints
of our technonogy. For some, your trick may seem like ESP. But to
others, it can be demystified. Clever concept nonetheless.
If I chose the card beforehand, the program removed the "wrong"
card. If I chose the card while looking at the screen, it was
It wasn't correct, I'm proud to say. I read about it in the

From: Jockel Deadeye :
Wow! I tried it several times and I must confess that you always
managed it to pick the right card! At first, I tried to find an
logical explanation for this. I used a randomly generated number
between 0 and 1 an multiplied it with 26. Then I began to count
through the cards, beginning left, until reached the number, which
was the result of the previous calculation. I choose that card and,
guess what....you or your program also did so!! I tried it at first
3 times in a row, then I paused for 5 minutes, then 8 times, then 3,
then 4, the 4 again and finally 2 times. I don`t know why I did so,
but I tried to somehow override the psychological link to my brain.
Furthermore I wore a metal helmet to prevent any connection to my
brain by electromagnetic waves. I accidentaly wrote down each number
I tried and the letter for each, based on the alphabetical order.

was going on!!!! You're able to influence any random number

Love your ESP experiment. I teach a course in applied statistics
in psychology. Your experiment is perfect for gathering data from
the class to summarize and consider the possibility as to whether
there is empirical evidence for ESP. Much additional misdirection
is supplied by asking the class to consider the probability model
that a particular card is selected and then removed in the first
stimulus presentation. With much discussion the class data appears
to unequivocally provide scientific evidence for ESP since
invariably the probability that 20 people or so all have their card
removed from the second stimulus presentation is statistically
significant. The subsequent discussions of how the psychology of
ESP might explain this apparent phenomenon is richly attended to.
Since no one is aware (of how it really works) the class gets a real
live dose of how good theory must explain and drive an experiment
and that statistics, however significant, is not the salvation of
sound scientific analysis. No theory of ESP, however good, can
explain a non-ESP event like your experiment. And data which
appears to be collected to explain an ESP event, but in fact is
collected on a non-ESP event aptly shows how the wrong theory
applied to the right data produces bogus science. The best part is
how to explain why some people swear that their selected card was
NOT removed. Then were into some real psychology of how the mind
works. And all that whiz-bang jazz in your explanation page about
technology sensing your eye movements or anticipating how your mouse
event can be interpreted is priceless. And as a teacher of JAVA, I
loved the hype about downloading the JAVA code and inspecting it for
clues to the ESP event.
Outstanding! And thanks for the teaching prop,
I am a Ph.D. with seventeen years' experience in neuropsychology and
mathematics, and I must say I have never seen anything quite like
Even in the eighties, when the U.S. government was actively
encouraging and funding experimentation with increasing hypothalamic
mass in voluntary subjects, my colleagues and I were never able to
produce results so strikingly accurate. I suspect their techniques
have become refined since I ended my participation in the Program in
1991, and that the push to synchronize vertical and horizontal
refresh rates for CRTs and computer monitor displays with
frequencies harmonically related to theta brainwave function (that
is, even multiples of the frequencies at which the brain is most
responsive and aware) is a direct result of this refinement. It's
obvious that this planned synchronization has resulted in the
ability to conduct bi-directional thin-client transfer of
information between subject and centralized artificial intelligence.
This has profound application in today's political climate.
The ability of our government to monitor the thoughts of
individuals, and process those thoughts automatically for motive and
intention, is an important advance in the fight against terrorism.
There are also exciting possibilities for inverse
applications--that is, the ability to push data to individuals
electronically rather than simply pulling brainwave data to a server
for processing. Because the information link is bi-directional, it
allows for massively parallel processing of computationally
intractable nondeterministic polynomial (NP-hard) problems, such as
those encountered when factoring products of large prime numbers.
Remember "Sneakers"? Factorization of large primes is directly
related to the ability to break complex cryptographic protocols,
such as the RSA and Diffie-Hellman protocols currently in use by
most governments and financial institutions. This is a classic
application of the "Chinese Television" method of codebreaking, but
on a much more massive scale--processing by billions of Web surfers,
without requiring their acquiescence or consent. The SETI project,
as I am sure you are aware, has been using this method (albeit with
computer processors, not human brains) for quite some time now, but
the technology you have demonstrated allows, for the first time,
practical applications for government agencies such as the CIA and
NSA. Just think of the possibilities--foreign cryptographic measures
broken in mere hours, with the (unwitting) help of a few billion Web
surfers across the globe!
Whew, just kidding there. I'm no Ph.D., just a computer programmer

I got a real
kick out of your source code (who knew pipe symbols could be used to
such effect?) and was rather surprised at the, er, "innocence" of
some of the self-described educated people who were taken in by the
references to Java and your handy HTML comments, not to mention the
"ESP test" itself. Which makes me wonder, how do these people react
when they realize they've been taken by a parlor trick? I'd like to
believe most of them laugh and shake their heads, although I suspect
many persist in their belief in various paranormal and conspiracy
theories ("My Computer Has Really Cool Eye Monitoring Hardware Dell

Dear Mr. Pickover: I tried your experiment with cards many times

eyes is not a red herring and = also affects the outcome, the
probability of a random success is just = 1/36, and my result (about
1/5 to 1/6) was way above the expected. = Stiil, I wonder why almost
everybody else reports the astonishing 100% = or nearly 100%
success. I don't doubt the veracity of these respondents, = just
wonder. I don't think you'd be willing to shed light on this puzle,

Dear Dr. Pickover, I am amazed and fascinated by your experiment. I
don't seem to understand what relevance does"Quantum Consistency
number" has in this experiment? because,once it was 357 and the
answer was correct and then it was 950 with three flashing lights
and the answer again was correct.
I tried the experiment three times and was right each time.
When I contacted your site I was feeling somewhat misfortunate
and powerless due a recent series of irrelevancies. However I
picked the right card three times in a row and immediately felt
better. I decided to test the 98% accuracy claim by doing the
trick 100 times. On the first 98 times I picked the right card.
The next two times I picked the wrong card. Amazing. Next I
decided to extend the investigation to 47150 trials. The first
46207 times I picked the right card. Then I picked the wrong
card 943 times, thus attaining a 98% record. Amazing. I am
convinced that I can pick the right card 98% of the time.
Amazing. How do I do it? I think there is a microphone in my

Hi, My name is Kayla and I totaly belive in all thinge that
revolve around ESP but how did you do that?!
dear cliff, i did an experiment of my own. i decided to pick one of
the cards,say it out loud,but in reality picked a different card in
my mind that was my choice. i clicked on one of the eyes and it said
that it had removed my card. however,now with one removed,five
remained. neither the card i said out loud,nor the card i chose in
my mind were there. this means that one was taken away and one was
swapped with another card. how do you explain that? i would love to
know as i find it is obviously either a trick,an illusion or both.

Hi, My name is Tara M.
Your experiment was really fascinating. I tried it about 15 times
and all were correct whether or not I looked at the screen, picked a
random card in my head, looked at one while thinking another, moved
the cursor, picked a different blinking eye or the same eye over and
over for a differen t card, etc. The only thing that did not work was
if I chose a card that was not one of the six on the screen, for
example, the 10 of hearts. If it were ESP this would have kept all 6
cards and not eliminated any. Besides that, I don't think ESP works
via computers, it would be hard to "perceive" remotely and also to
attend to all who were logged on at once. Obviously though, your
knowledge of either programming, numerical statist ics, physics, or
all of the above are excellent. Like the others who wrote in, I hope
you will eventually post your results, and explain the tech nique used.
Thanks for the experience!

Isn't the first pick usually the third card and the first eye chosen
the third eye?

YOUR ESP EXPERIMENT PROGRAMED THE REMOVAL OF THE WRONG CARD.
REMOVED WAS NOT MY CARD CHOSEN.
BETTER LUCK NEXT TIME.
From: "Karen L.,
This experiment is absolutely awesome. I did it over and over and every
time you were correct. The scary thing is if you can ESP the cards that
we randomly choose, what else do you know about the future? Great job
at this. Keep up the good work!!
From: "Stacy D."
I'm curious and have no clue - how does it work????
From: "Tori T."
I took the ESP test SEVERAL TIMES. Your computer got it right every
time! I'm scared!
HI, I'M SONJA. I DID YOUR ESP THING WITH THE CARDS. IT WAS RIGHT EVERY
TIME. IT WAS SO KOOL.
From: "Andrew T."
WOW! Me and my five friends played the game, and it turned out we each chose
different cards and you removed ALL SIX of them! WOW! It was AMAZING!!!!
From: William K.
You were right every time, but it's time you got out of my head. And
when you go please take John Poindexter and all the other boobs at Total
Information Awareness with you. Thanks.
From: "Jared W."
I don't think it was ESP, Mr. Watkin.
Could you tell me honestly?
From: "John M."
The way I think you carry out the ESP experiment is that u have a
frequency analyser installed in the software and when one says the name
of the card aloud, the software can match the various frequencies in the
voice to that of the chosen card and in doing so figure out which one it

Wow--all I can say about the ESP test! I am absolutely baffled at the
results! What's "Quantum Consistency?" Mine was 958..

I thank you in advance for reading this, if indeed you are.
I try to keep an open mind about everything, and i do mean everything.
However, I find it very difficult to believe that a website could be
instilled with the psychic energies and/or perceptions of a living being.
Still, I am (almost) completely devoid of any viable theories as to how the
program might work. I have conducted a few controlled experiments and still
have come up empty.
THIS IS THE IMPORTANT PART OF THIS E-MAIL!!!!!!!!!!
I kid you not good sir, if you do not send a reply to this E-mail in some
form of an explination as to how you accomplished this amazing feat, you
have ruined a young boy's life. I will not stop trying to solve this riddle
until it is answered. (Keep in mind that should the
answer involve computer programming techniques, please keep it VERY simple,
i know little of computers) In either case:
I MUST KNOW HOW YOU DID THIS!!!!!!!!!!
Thank you for your time and evident genius,
From: "Le Tigre"
Ok I took your test to see if the computer can read your mind. Here is what
I took it quite a few times and it was right. But then I looked at the
feedback page, and someone said something about choosing the card beforehand
and not looking at it. So I did that and did not move my mouse. Guess
it was wrong every single time that I did that. So I'm thinking it has
something to do with eye movement and/or pupil dialation. Hence all the
eyes!!! hehehe. Am I getting close?
I thought at first that it had something to do with the order in which the
eyes were selected but....
Oh i guess that's why it told us to 'stare at your card'.
HOW do you do it? I tried it about ten times and couldn't figure it out! A
lot of the time I chose ahead of the time and didn't even look at any of the
cards and one time I even looked at the wrong card and it still got it write!
It's totally creepy!

''WHAT'S MY BIGGEST FEAR AND WHY DO I FEAR IT'' ....... IV'E BEEN WANTING THIS AWNSER FOR A WHILE.
It has to be something visual that draws your attention towards particular
cards. It's nothing to do with what you click on - that's irrelevant, but
there's a visual manipulation of some sort to draw your attention towards a
particular card. It may well be shading.
The reasoning is simple: if you pre-select your card it is invariably wrong.
If you choose while looking at the page, it is correct. The animated gif is a
nice distraction from what is really going on.
From: Joseph L
Your ESP trick baffled me for most of the morning. I even wrote a little
script to generate random numbers for the first eyeball picked, the card
picked, and the last eyeball to click on. After going through it numerous
times, I decided to look at it from another perspective.
From: "Paul B"
I have no idea how this works. I can handle algebra, so the math behind
your algorithm is way beyond me. However, I noticed that if make my
card selection from the cards that remain after my first pick, and then
return to the pick screen, the program never selects the card I have
chosen. I don't have the math skills to figure this out, however. Paul

You've got me questioning reality now, thanks.

wow you were so right. my friend and i always think alike and i want to
no if it is esp or coinsedince. we once wore the same outfit and we
didnt plan it and we also do alot more things. please please please
email me with your comments. we are both very interested and also

Right ! I have had enough, i own and run my own business - a newagents and
at the minute all of my customers are talking about it - one of them thinks
he has sussed it out after
spending 28 hours trying to master the technique!
i thought to myself that all of my customers are refering me to this website
and so i thought to try it myself and it is absolutly amazing!!!
shouldn't this technique be out in the real world making millions and
millions of dollars ?????
i live in england and found the site amazing that i have made a poster of
the site to make sure friends and family go onto it for sure and check it
many, many thanks for this spooky adventure you have sent us all on, i will
find the way you do it ! , you will see !!
thank you once again,
