Psychic playing card test. Please do not look at vote before voting!

[Interesting Ian]

OK, if you would please vote before seeing how other people voted, I would appreciate that. I have the card in front of me just next to my keyboard. I will leave it there during the duration when people are voting. Voting will end on Monday 15th March at 5pm GMT. At that time I will reveal the pertinent card.

The 10 cards I deliberately chose from the deck. However the card you might either clairvoyantly "see" or/and telepathically read from my mind was chosen randomly from the 10 cards. Moreover it's position in the voting list was also determined randomly. Also the position of all other cards was chosen randomly.

If people like, they could say in this thread which card they chose and whether they are a skeptic or believer.

eg relevant card - Believer

Edit to add: I have pm'd Mercutio the relevant card and he has acknowledged.

[Mercutio]

For the record, Iam has PMed me the identity of the card. I will not be voting (duh), and I cannot be bought. I thank Ian for his trust.

[renata]

I remember reading about some studies that say given a limited amount of choices people tend to pick for a particular one in the sequence. In other words, all things being equal, in a group of- say- 10 options, and a request to pick one randomly, some will be picked more than others. I am unable to have any backup for this, and it could be pop psychology. Perhaps Mercutio would know?

Anyway, it is possible that a card in your poll will be picked more often due to that phenomena- if I am remembering its effects correctly.

[TLN]

Which card do you feel you can psychically detect?

Since there's no option for "none", I will not be voting.

Penn & Teller told me it's the 3 of clubs.

[Denise]

I voted Jack of Diamonds. Just a guess as I am not "psychic." How do we know that you even have any cards at all?

[specious_reasons]

Ian, do you mind if I ask a few questions?

What is your hypothesis?

What was the process for the card selection?

Yes, there's a difficulty here. That problem could be eliminated by averaging out over quite a few of these tests.

I am testing out the hypothesis that people can detect the card next to my keyboard through anomalous cognition.



What was the process for the card selection?

The 10 cards I deliberately selected myself because I didn't want, say to have 2 Queens, or any aces (as psychologically people might be drawn to aces).

I picked the relevant card by using the hundredths of a second digit indicator on my stop watch on my digital watch. You know, each card was assigned a single digit. I used a similar method to determine all the positions of the cards in the voting list. :)

Don't a lot of mentalist magic tricks work on this sort of principle? Yes. I used a technique like this to surprise the hell out of my dad. (And he actually thought he had free will about what card he was going to choose! Bwaah-ha-ha-ha!! Little did he know that 75 percent of the people, when presented with a set of playing cards in the way I presented them to him, would select the third card.)

Actually, there are a lot of techniques along these lines. I noticed David Blaine using a different technique in one of his tricks. I recognized it as a technique that was published by Martin Gardner in one of his "Mathematical Games" columns.

For those who are interested, there is a popular technique called "Magician's Choice" or "Equivoqué" that can have a powerful effect upon those not familiar with it.

For the time being, I'd assume that no such techniques are involved here.

[Paul C. Anagnostopoulos]

I did the best I could. When I let my brain wander into the land of playing cards, I started seeing playing cards all over the planet. I haven't learned how to address Ian's particular card.

~~ Paul

[Sindai]

I skimmed the poll for a second and asked my brain to return a random card. I got "jack of hearts." Since that wasn't available, I decided to go with "jack of diamonds."

[Ed]

I am not sure what this means. My first guess is "nothing". After all, there is no way of knowing what people would have picked in this series if there were no woo rays flying, right? Therefore, one would not know if those that chose the correct card are psychic or if they just love that card. Guess I don't get the point of the bandwidth use.

It is true that with just the one test that nothing much can be inferred. Nevertheless, if a number of such tests were carried out, that might be more interesting.

[Lothian]

I predict that having a 7 as the seventh card down will make it the most popular. You may have subconsciously put it there as well. It also fits quite close to brown’s trick.

No, both the target card was picked randomly and its position in the voting list was selected randomly.

[Zep]

3 of hearts. Non-believer. Closed eyes and picked the first number I thought of in the range from 1 to 10.

HOWEVER, This is not really as "random" a test as it would seem to be. Already we have seen the available pool of choices from which to choose, so already we may be forming "likes" and "dislikes", ie. a prejudicial outcome. For example, if the thought of a random card from a complete deck popped into my head, it may not be in this subset. So I may feel inclined to choose a card similar to my thunked card - same suit or value, perhaps. This would make it an inexact and influenced choice, not really a candidate for "anomalous cognition" at all.

And while understanding the limitations that Ian is working under with the poll technology of the forum, it is still possible to see the previous outcomes beforehand and so make a choice possibly influenced by that in some way. I'm pleased to see that Ian has tried to avoid this, although this limitation seemed to be beyond many well-known psychic testing investigators in the past.

[T'ai Chi]

I have no experience with remote viewing (but do meditate).

I 'sensed' the 4 of Diamonds even before reading it in the list of choices, so I stuck with that as my selection.

[Aoidoi]

heh, I picked 7 of clubs as I found it the least significant (not a face card, not a round number nor a high/low extreme, always thought clubs the least interesting of the suites).

Amusingly, it's in the lead as the guess at the moment. I suspect a lot of smart-*sses like me did something similar. :D

[Peskanov]

To add interest to all these little experiments, some kind of control group should be used.
For example, asking some volunteers to pick a car from Ian's set using different criterions:
- Choose using personal preferences.
- Try to guess the card of other person, not Ian's card.
- Choose randomly in a short time.

Without any reference for comparison, I don't think this experience is interesting.

(btw, I chose 4 of diamonds, but I think it could be due that this card is important in some game I used to play years ago)

Fun thread Ian.
I picked the 7 of clubs before I even realised there was a list to choose from. Luckily it's on the list and wouldn't you just know it? It's in the lead.

[TheBoyPaj]

2 of spades - Skeptic.

As for my method, I didn't look at the list of cards, but I closed my eyes and tried to imagine where your computer was in relation to myself (which direction from my house, approximate distance). I got a strong image of the 2 of spades, and was pleased to see it on the list.

I still don't expect to be right!

Ian,

The thing that belivers don't seen to get is that without proper control, in this case for example, you end up with nothing more than cocktail party chat. If you did a number of similar exercises and obtained results that were "interesting" because of the lack of hypothesis theory rigorous design and so on, all that would result is yet more "it means this no it dosen't" crap that we are all so used to. The fact that believer research is evidentially designed with flaws precludes any firm finding and fuels the believer mind set. This lack of rigorous design suggests to me that those that really know better (Schwartz comes to mind) do so that they in fact can say that the results are "suggestive" or "equivical" rather than "negative". A lousey experiment proves nothing and really is not any more interesting than anything else we may observe in our day to day life.

[voidx]

My visualized card was covered with naked ladies and as such I was distracted (they were being oh so naughty) from gleaning either the suit or number of the card. Are you sure your thinking about the card Ian? One of them also turned into a pitcher of beer. It was all rather odd I must say.

7 of clubs - Skeptic

I played along as well as I could. Just closed my eyes, pictured I.Ian sitting at a computer (your avatar is you, no?), and next to him in my mind's eye was a black seven. Scanning the list, I saw 7 of clubs, and there you have it.

It seems it is being chosen at 3 times chance rate. Interesting... could it have to do with the number 7, or it's perceived "random" position in the list? Can't wait to find out and participate in more fun experiments!

If this is testing others peoples psychic ability, it must be totally random without your notions of psychology determining any part of it.

It depends what you mean by a "valid experiment". The vast majority of people on here are skeptics and they might tend to "psi miss". Also people will be psychologically disposed to favor certain cards. And people will be psychologically disposed to pick near top, middle, or bottom of list, or wherever. People might just simply guess just for the hell of it and not try to open up to any feelings.

I can't do anything about the psi missing. But all the other problems can be eliminated by doing a large number of tests. Even the guessing won't matter if there is any genuine anomalous cognition; it will just reduce its overall significance which can be made up by a sufficiently large number of tests.

Of course you can still object by pointing out that Mercutio can vote even though he's not supposed to, and I can, and I can pm others to tell them the card. So no, it's certainly not immune to cheating. {shrugs} But neither is the testing totally useless.

As for voting more than once, I never realised that it was possible. Never has worked for me in the past. :confused:

I agree though that "psi missing" might make the whole exercise a waste of time, although I rather feel that's not what you had in mind.

There's a way to clear out your cookies etc., and vote again. And let's not forget sock puppets.

But the evidence suggests that people might tend to get the correct rank but wrong suit and so on. So I felt that I should try to eliminate that element. Of course playing cards are unsatisfactory. Zener cards would be much better. Just that I don't have any, although come to think of it I could just print one out . . hmmmm. Oh well. We've stuck with this test for now.

Yes, people can cheat. But would they really bother to cheat? I mean what is the point? I can't do anything about that at the end of the day apart from not do the test at all.

But if you think you're so clever and can do it without any cheating, then go ahead and set a test up. Use zener cards though. These results I've got are ridiculous even if the 7 of clubs does transpire to be the target card.

[VicDaring]

I'm reasonable sure I could detect the yellow 7 from an Uno deck, if given the opportunity. But then again, who knows?

This is not the beginning of an argument, I am simply stating a few facts. What you are doing

-Does not control for position bias.
-Does not control for yea saying (or nay saying)
-Does not control for inherent preferences
-Does not have a clear hypothesis
-Does not control for multiple guesses

You really don't know why a match is a match. Doing it again dosen't really help matters since you don't know the biases of the new respondents. You have too many things going on to make any sense of the results.

Ian, I'm not interested in setting a test up. I thought we were just chatting about your test. I was just trying to point out that cheating was easy if one wanted to do so. Because a person can cheat, then the results would not be valid. Doing more and more tests would not make the results any more valid when there aren't controls to stop people from cheating.

A hypothesis is not required. I am simply collecting data to see if is of any statisitcal significance. Of couse I agree that vastly more than one test would be needed before we could even reach the most tentative of conclusions.




-Does not control for multiple guesses



But there's nothing I can do about that should people feel the strange urge to do so.

Any biases will get ironed out by a sufficiently large number of tests.

What things? How do they impact upon the results? More details please.


You know, I absolutely knew you would say nothing of any substance after I asked you to specify the defects of my experiment and how you would improve it. Psychic ability on my part? No, in all comments in the past you have had never said anything worthwhile or of any subtance, so by inductive reasoning I reasoned you wouldn't this time either.

And I was correct!

At the end of the day I don't believe I can do anything to stop people from cheating should they feel a bizarre need to do so.

Cheating, fraud etc are always possible even in parapsychological research, never mind other branches of science. And certainly one could not hope to eliminate this problem completely in an informal fun experiment like this! :rolleyes:

I have not seen the results ahead of time, I did not read this thread prior to voting...

I gave my vote to Jack of Diamonds. That one stood out to me more than the others. Just for fun, I'll try to guess the order at which Ian will find the cards in his deck (from top to bottom):

J of Diamonds
10 of Clubs
4 of Diamonds
2 of Spades
Q of Hearts
8 of Hearts
3 of Hearts
K of Spades
9 of Spades
7 of Clubs

The only person that would be cheating is me! I could pm all the believers, Max, Clancie and whoever, and tell them the correct answer so they could vote accordingly! Oh yes, and I'll tell them to use all their sock puppets and clear out their cookies and . . . .

Dear me!

I must remember not to carry out any more tests unless it is as tight as normal parpsychological reseach! :mad:

Thanks for pointing out my stupidity Denise! ;)

I chose the Jack of Diamonds, at random. I do not believe in remote viewing, esp, etc.; I think if anyone guesses the card, it will be due to coincidence.

well, technically, I could cheat, too...and, like you, I kind of resent the implication! But...I absolutely understand that this does raise the question of cheating...and I think that, of course, no matter how significant your results might be, they should be distrusted until they can be replicated with the possibilities of cheating that have been pointed out here fixed. (terrible grammar, but I am too lazy to fix it).

That said, is it useless? Of course not! At two levels...one, it is a nice exercise in experimental design. two...suppose we do find significant results--I can think of a million reasons to try to replicate with the same subjects and better controls!

...Oh...I would also like something explained to me. I understand about multiple votes, clearing cookies and voting again, yadda yadda yadda...but unless Ian or I give the answer to someone, what advantage does that give? We have more people voting randomly, according to the null hypothesis. Of course, there are no guarantees but our words of honour that we will not give out the answer...but hey, all I have here is my word, and besides, this is just a fun little test.

I focused on Ian's avatar and I got an impression of red more so than black, followed by hearts more than diamonds. Then I had a surprisingly strong image of an 8.

Luckily for me, the 8 of hearts was on the list.

I don't know about advantage but it could really screw your test up. For instance, I could vote many times to show them briefly as having 25 people voting for each card. It might be hard to figure out which votes to throw out because you wouldn't know what vote was a vote by a person voting once, or by me voting to make them all even. Also, by not requiring people to post what they voted for, you will not be able to tell who actually picked the card if say, 20 people claim a match and the card only received ten votes.

The only card around here is Boring Ian.

Why don't you jam a 2x4 into one of your bodily orifices and let us guess where it is?

I agree, that could be done. And of course, it would then be possible for skeptics and believers (if I might falsely dichotomize for a moment) to blame one another for doing such a thing.

But both sides also have an interest in seeing it done properly. Sure, exposing weaknesses is a nice way of demonstrating that they do exist and should be controlled for next time...but I think the discussion here has already concluded that this is far from an ideal test...so there is not much reason to screw the test up on principle (in my opinion, anyway). So why not behave honorably? Both sides might accuse the other of having a reason to cheat, but in truth both sides have every reason to be honest! Both sides want a fair test--skeptics because they are confident it will show no effect, believers because they [hope, are confident, somewhere along that continuum] it will show an effect. The only reason to cheat is if you lack the courage of your convictions, and around here I don't think that describes too many people.

Of course I could be wrong. But...as I said, discussion has already established that enough could happen that this cannot be a scientific test. So why screw it up?

[specious_reasons]

Hey Ian! Just want to point out a couple of things:

You should pre-select the number of tests. That way you can't stop right when you're having a stroke of good (or bad) luck. Preselecting the number of tests and running through all of them gives chance a chance. :)

I'm rusty on my probability, but one test is definitely not enough to "show" anything. You suggested 10, any reason or a guess?

Given the way the poll results are looking, it looks like there might be some selection bias. I know I selected a popular card on impulse.

[Ratman_tf]

7 of clubs. Skeptic.

I had no special insight, I just moved my mouse over the choices going 'Wiggity wiggity wiggity' and clicked one as randomly as I could.

Here's another possible data point that I hardly ever see addressed. What about a null reading? Are psychics 100% reliable so that a failed reading just never happens? ;)

Here's another thing, it seems that everyone is guessing at the card. (Even me) That's not what Ian asked.

Should we have even voted if we were just guessing? Doesn't that flood the poll with useless data?

You're forgetting that others can cheat to turn a positive result into a negative. For example, we might all be getting a strong image of one card but, damned if we're going to give you the satisfaction of being proved right, we all pick different cards and deliberately blow the test. We can also see before voting how others have voted and so vote to spread things out evenly.

There are probably ways that we can cheat to turn a negative into a positive too, with a bit of thought. For example, if lots of people chose to vote for the same card, picking that card at random, that could still be taken as support for your idea when the results were in. Even if the wrong card was picked, it might be the right colour, the right suit or also a picture card.

[B]Hey Ian! Just want to point out a couple of things:

You should pre-select the number of tests. That way you can't stop right when you're having a stroke of good (or bad) luck. Preselecting the number of tests and running through all of them gives chance a chance. :)



Ideally yes, I still think people are taking this test too seriously though.




I'm rusty on my probability, but one test is definitely not enough to "show" anything. You suggested 10, any reason or a guess?



I've decided this test is no good at all. 10 would really be the minimum number, but it's imperative that I know what skeptics have voted, and what believers have voted. People aren't saying, so I'm going to have to think of a new test where the options demand people declare whether they are believers or skeptics. I need to do this because of the phenomenon of psi missing.


Given the way the poll results are looking, it looks like there might be some selection bias. I know I selected a popular card on impulse.


It is also clear that I need to use zener cards.

[Interesting Ian]

Should we have even voted if we were just guessing? Doesn't that flood the poll with useless data?

I was thinking of asking people not to vote if they're just guessing. But this is a skeptics board. If I had done that scarcely anyone would have voted at all.

You have to build in controls that assume the worst. Just because you don't think people will cheat is not a good enough reason to allow them the ability to cheat. That is what designing a strong testing protocol is all about.

Well there's nothing I can do about it if people refuse to name their choices in the actual thread {shrugs}

So it's either put up with the possibility of cheating (ie deliberately screwing up the test for no reason at all and going to some considerable effort in doing so), or not do a test at all.

And it's difficult to know what I could do about the possibility of myself or Mercutio cheating. Well, obviously I can prevent myself from cheating, but I meant to the satisfaction of other people.

I still say that people are taking this test way way too seriously. To say the least, it never was aspiring to try and achieve the watertight protocols adopted by proper parapsychological research! :eek:

I think people will be honest and the result will be interesting but, as you say, because of the lack of controls the result won't actually tell us anything about the existence or otherwise of a paranormal ability we might have to divine which card you have selected. A failure won't prove you're wrong and a success won't prove you're right. Should be fun though :)

In order to judge if the results can not be explained by random chance, you have to be able to calculate the probability of a hit. With the book test as originally suggested this is not possible. With the playing card test you need at least 260 trials to calculate a chi-squared significance. So you're right, Zener cards would tie this down to manageable numbers.

If you want to know how to calculate significance, have a look at this page on calculating chi quared values:

I originally decided to post this question for laughs, but now that I think about it, I realize that if psychic powers existed, it is possible that they might feel like random guessing.

We don't need to worry about that until the results are in. But the test in isolation tells us nothing anyway. I'm going to do a zener card one soon and also ask people their beliefs in the actual questions. You see there's 5 different zener cards, so if I ask whether people are believers or skeptics as well, that'll take up the 10 options. And I just need to find images of the 5 zener cards. Should be a much better test. Of course I still can't stop people from cheating.

Actually we do, what statistical method we use can influence the degree of statistical significance. Therefore the method should be selected in advance to keep the results from being influenced by subconscious bias (or conscious, but if you wanted to cheat it would be far easier simply to vote ten times for the correct choice).

Just to stress that the target card was randomly selected from the 10, and also it's position in the voting order was randomly determined. So there's no question of me having a psychological propensity for picking a certain card and putting it in a certain position, nor is there any trickery of any nature involved in this test. I absolutely assure people of that.

I'm not exactly an expert statistician either, but you could for example analyze either how often the correct card was the one that was picked most often, or alternatively how often it was one of the five cards selected most often
Anyways I think the it's a good idea to device a test rather than just have a discussion even if it isn't waterproof. Also it's fun - I think I'll go post on the "can you guess this book?" thread too.

This test is an exercise in data mining. You have not specified the statistical tests you will use in advance. You have not specified what you expect to find (although you have hinted that you would like to find skeptics missing more than by chance). To properly analyse the data you should not know which guesses came from skeptics before you analyse the data (i.e. it should be a blind procedure).

So a suggestion for a future test: instead of using a poll, have the guesses (and the degree of skepticism in the respondant) PM'd to a third party who will tabulate the results and substitute the respondant's name with a number. They can also screen out multiple responses from the same person. Then, you can try to identify a subset of respondants with above or below chance results (after running the test many times). Only after completing your analysis would we all be allowed to see which respondants were skeptics.

Absolute rubbish. Psi missing is one of the more consistent patterns in parapsychological reseach. This certainly need not imply it is likely to be repeated here given that skeptics feelings will not be exactly the same as in proper parapsychological testing.

You probably think that you have these big thoughts and are misunderstood, don't you? Drown your sorrow at not being recognized by your inferiors for the intellectual giant that you are? I am sure that your therapist has alluded to this sad fact, perhaps in a way too subtle for you to comprehend. You might ask her (it is a she I suspect) to come right out with it. You cannot do it with the people around you since they have tried and now they simply don't trust you.

Really? How does one tell psi missing from just regular missing? How can research that is trying to determine a psi effect assume such a thing as "psi missing"?

To me, it sounds remarkably like a way to explain away negative results while keeping the positive results. Or worse, to interpret negative results a positive results, like saying, "The ten consecutive prove that "psi hits" are real, and the the ten consecutive misses prove that "psi missing" also is real. How can you lose with such a rigged system?

Maybe you were making a joke, Ian, but Mercutio makes a good point. Shouldn't you let someone familiar with statistics make the evaluation? Since you have already trusted Mercutio with the actual card, it seems you could trust him a little further to do the analysis, especially in light of his knowledge of such things. How about it?

Psi missing is scoring below chance to a statistically significant extent. It's not rigged at all. First of all they establish who are the skeptics and believers, and then carry out a test to investigate the hypothesis that believers will psi hit and skeptics will psi miss. So even if overall the result is according to chance, if skeptics do tend to psi miss in the experiment, and believers tend to psi hit, then that would give some evidence for the hypothesis.

You see?

Yes, it is clear that people psychologically are favouring certain positions in the list. Thus, even if I used zener cards, it could well be the case that people would prefer the 2nd and 4th positions on the list no matter what the symbols are there. This is not to mention that people might favour certain symbols eg circles over wavy lines. Thus in any single test one would need to know precisely the extent of this prejudice before being able to come to any conclusions ie any anomalous effect is swamped by peoples favouring certain positions and symbols.

Now one way I could get around this were if I carried out 2 tests, one where I do not pick out a card and people just arbitrarily choose a card, the other where I choose a card and people try to psychically detect it. The other way is simply to carry out a very large number of tests.

Yes people do. That was one of the original problem with the proper birth of parapsychology in the 1930's. People did prefer face cards. This is why zener cards were developed.

However, I felt that simply putting something like the Queen of hearts in text, as opposed to presenting a graphical representation of the Queen of hearts, would nullify this tendency. It seems I was correct. However people are obviously favouring the 7 of clubs. I was half thinking of substituting this card for another card as well. Oh well.

Psi missing is scoring below chance to a statistically significant extent. It's not rigged at all. First of all they establish who are the skeptics and believers, and then carry out a test to investigate the hypothesis that believers will psi hit and skeptics will psi miss. So even if overall the result is according to chance, if skeptics do tend to psi miss in the experiment, and believers tend to psi hit, then that would give some evidence for the hypothesis.

You see?
Again, that sounds like data-fitting to me. "Oh, he missed because he is a skeptic", sort of thing. As has been discussed here, even in well-controlled tests where there is some suggestion of telepathy, the number of hits is so close to random that it requires meta-analysis to support the psi hypothesis.

I also recall reading in one of Randi's books (don't remember which one), where a researchers had suggested that individual subjects were fluctuating between "psi hitting" and "psi missing", depending on their mood. They then threw out all the "psi misses" because it was "obvious" the subject was unconsciously picking against what his telepathy saw. It made their results look remarkably good. Go figure.

Psi missing does make data mining easier, but if the protocol and statistical method is specified in advance, you could easily make a legitimate experiment that included psi missing, and even fluctuation between missing and hitting depending on mood.

You mean a skeptic actually has psi abilities, but because he's a skeptic he uses them subconsciously to produce worse than average results? Wow, if we could throw some sex in there, too, Freud would be dancing in his grave!

How about doing the experiment first, tallying who had positive and negative results, and then letting a third party determine who is a believer and who is a skeptic?

And this is something else I've screwed up (as well as not using zener cards etc) by mentioning it in the first place. Basically there is no point in doing any future testing on this board since people will have read this thread, know about psi missing, and this will subconsciously effect their voting.

I'm going to have to do any further testing on another board. Any suggestions anyone? I need 10 options for the 5 zener cards because people will have to say whether or not they are a believer or skeptic as well as choosing a card.

Maybe I could carry out this experiment on 3 or 4 boards. Any suggestions welcome.

Certainly you could set up such an experiment, but to what purpose? The single and most important thing is to determine a psi effect. To that end, one need only test people who believe in and think they posess psychic powers. If they cannot on average have significantly more hits than misses, then it is pointless to try to find out how mood or skepticism affects an effect that has not been demonstrated.

Essentially, paranormal researchers should prove they can do simple algebra before they move on to calculus.

You are starting to see the light. You are so close to an hypotheses. Have a good think. If the same experiment was done on a board of believers as one of sceptics, would you expect the same results ? If not why not ? What would cause the difference ? How can you test it to ensure that the only reason for any difference must be due to your supposed reason ?

I chose 3 of hearts in the almost certain knowledge that it would be the least popular choice as the first card in the list. BINGO :D

I'll have to disagree here, they need to prove some effect or another, but it doesn't have to be more hits. Less hits would do the trick, as well as some sort of patern to the hits - presuming this patern could be replicated.

This illustrates 2 fundamental problems.

[list=a]
People are ignoring my request to go by their feelings about which is the correct card.
Some people are deliberately choosing a card which will even out the scores thereby proving evidence of no psi.
[/list=a]

And this is also where psi missing comes in. Skeptics sub-consciously want the experiment to fail, and therefore will use their psi abilities to choose a card which is not the target. Or alternatively, in common with AC, they might choose a card which they feel people will not choose, either because of its position in the voting list, or because of the rank/suit of the card.

[asthmatic camel]

Precisely Ian, that's why so many of us find experiments like this of such little worth.

Son: "Oh, that's ok Dad, I really passed the test. My teacher said I was Psi Missing!"

[TheBoyPaj]

Your experiment also assumes that most people have psychic powers and that these will manifest themselves on demand. People who claim psychic powers often say that they can not turn them on and off, and that it is only over time that they become apparent.

So, instead of doing one test and seeing if there is a skew to the chosen card, rather you should be doing many tests and seeing if any one person outperforms chance. After all, if such powers exist, chances are they will be better developed in certain individuals.

I have in my mind a live testing webpage, with video feed of a person chooing Zener cards in one corner, a simple click and select form for choosing cards in another corner and a chat applet for communication with the tester. Results could be calculated automatically and displayed almost instantly. If I had time I'd do it myself, but if anyone wants a project...

And some skeptics, to counter any proof of psi missing (which could in turn prove psi) deliberately tune into their real psi abilities to psi hit. The result of which makes for skeptics a nice bell curve centred on chance. Proving that psi-missing and psi hitting are occurring equally and making it look like psi does not exist and we are merely seeing the results we would expect. Ba$tards.

I agree, but why make things difficult. Go for the straightforward answer with non-skeptics who think they have powers. Over a large number of experiments, you should find some of the "real" telepaths and their powers should work "some" of the time. The rest of the guesses will average out, and you will be left with a residual positive outcome. Once this has been established (which I do not believe it has), then you can go on to more complex variations. Investigators should not start out with the complex variations.

To use an analogy, Mendel had to show the basic patterns of inheritance worked (overall) before we could go on to complex questions such as mutations and linked traits.

Nowthen, if I have indeed guessed correctly, and the 3 of hearts is the correct card, what conclusion would you draw ? That there has been no "psi" effect or that there has been deliberate "psi missing" ?

Pointless exercise; six out of the ten cards are far more likely to be chosen than the others.

I've already addressed this earlier on today. Why don't you learn to read? To paste in what I said:

Yes, it is clear that people psychologically are favouring certain positions in the list. Thus, even if I used zener cards, it could well be the case that people would prefer the 2nd and 4th positions on the list no matter what the symbols are there. This is not to mention that people might favour certain symbols eg circles over wavy lines. Thus in any single test one would need to know precisely the extent of this prejudice before being able to come to any conclusions ie any anomalous effect is swamped by peoples favouring certain positions and symbols.

Now one way I could get around this were if I carried out 2 tests, one where I do not pick out a card and people just arbitrarily choose a card, the other where I choose a card and people try to psychically detect it. The other way is simply to carry out a very large number of tests.

[voidx]

PSI missing? Wow. That's a good one. You're trying to assign a negative attribute to skeptics. So rather than just us getting below chance, which is possible, it is now construed as a negative PSI ability. So you assume we have some PSI ability in the first place, which makes no sense. If we score less than chance, thats the entire explanation right there. In this sampe size we averaged less than chance. This is not really surprising I don't think. But you want to label that PSI missing, so any potential PSI hitting seems more impressive. You want to quantify any less than chance performances from skeptics, so that any positive performances by PSI'ers looks good. But we're not testing for how people miss, we're testing for people getting above chance results. This is just a potential distraction if you ask me.

Edited to add: your testing for the presence of PSI and so that must be shown in an above chance performance. To get less than chance does not invoke the possibility of the tested for phenomenon at all so why is it a PSI miss rather than just...a miss.

It really doesn't matter which cards are psychologically preferred. If the actual card selection is random, the preferred and non-preferred cards will be the target just as often. Over a large number of trials, the results will balance out. But this requires a sizable number of tests, and Ian has already indicated that he will not do this. In fact, he has not even completed his first test. If I had to guess (or use my "psi" abilities to read Ian's mind ;) ) I would say that Ian got bad results on his first test and immediately started looking for excuses. I suspect that had the 7 been the actual card, Ian would be trumpeting his "success".

Now, if Mercutio would reveal the card, I could see if this is in fact the case. I sense that Ian has a certain reluctance to do so, even though many of us here, including myself, would agree that a single test means nothing. Quitting and making excuses means quite a bit.

Ian said he would reveal the card on Monday, I believe.

I am certain Ian will reveal the card, either on Monday or when he is convinced the voting is over. Meanwhile, Tricky, I resent ever-so-slightly the implication that I would be more likely to break protocol than Ian would be.:D

Another problem is the selection of cards. There's no 5 or 6. There's also only 2 Diamonds, and Clubs but 3 Spades & Hearts. Before even looking at the results, I predicted that 4 and 7 would have higher results, and Spades and Hearts would have lower results. Looking at the results, that's exactly what I saw.

I apologise Ian. I'd missed that statement. The point still stands though. This experiment is flawed. Kindly design an experiment which doesn't waste posters' time trying to prove something which has never been conclusively shown to exist.

I don't know which card you chose, I'm not even sure if you are legit. Still, I'd like to know, if my choice was correct, whether or not you would consider me a psychic. Possibly it was a sceptic psi hit as I couldn't give a toss about the experiment and my psi powers were therefore allowed full rein ?

Please continue folks, nothing to see here.

[phildonnia]

I voted for 7C since it seemed like the most boring card in the group, and I figured it would probably be the least popular. Surprise! it was the most popular. I wonder what kind of psychology is at work here.

I don't think this will go a long way toward proving any kind of psychic connection. Since everyone has similar symbols and models in their minds, everyone will tend to choose the same thing when given seemingly random options. This is why men always choose the urinal second-to the left if there are no other pressures.

It's like those old parlor tricks where you think of a country that begins with 'D', and your choice is pretty easy to predict.

Anyway, I get no feelings about cards, so I just flipped a coin a few times. It came up heads 4 times, so I picked the first card in the list. I decided to keep flipping the coin to see how long it would take to get a tail. It took until the ninth flip.

True enough. I didn't realise about people clearing out their cookies and being able to vote multiple times before starting the thread. Doesn't matter though anyway, because a much greater problem is people looking at the votes before voting. Obviously many people might just ignore my request not to do so. This sure ain't no proper parapsychology test! But nor was it ever intended to be.

There's no point in voting if you're simply going to do that. This of course is another problem with the test which is beyond my control.

Agreed. :)

And, even apart from the methodology thing, the results are pretty much what one would expect, aren't they. Nothing to indicate a group of people with psi abilities are here at this board (and no one participating thought they had any psi abilities either so...no news there).

If people did an activity like this ten times (with different cards....or numbers, to make it harder) and kept individual records of how many times they were right, I expect we'd all -still- show a similar pattern that was just consistent with guessing.

I think that everyone has psi abilities, but that one needs to be in a certain frame of mind before there is any deviation from the statistical norm. It is true that any psi phenomena that really makes you sit up and take notice are of the anecdotal variety. It seems certain characteristic emotions are a prerequisite which you cannot simply switch on and off at will. But although parapsychological research only shows up a relatively small effect, it really does seem to be there :)

If my guess was right I will use it as proof against ESP because I’m not psychic!

The way that atheists are discriminated against is an outrage! We deserve just as much respect as any religious person! Which reminds me that all religious people are f***ing idiots that should be thrown in mental wards! I don’t have to tolerate their delusions!

I wasn't being very skeptical. I had heard that and never investigated myself. Apparently you are right. Sorry. But we still have the problem of sock puppets.

Well this sort of eliminates the "multiple vote" problem, doesn't it? As Ian readily admits, sometimes your psi works, sometimes it doesn't, and you can't tell whether it's turned on or not except by results. So if a person votes multiple times in "different frames of mind", then each vote is equally valid. If you have even intermittant psi abilities, then the number of times you pick the correct card will, with a large number of repetitions, outnumber the times you pick the incorrect card. The only thing that really matters is if you actually are picking a card off the top of your head, and not deliberately trying to force the vote one way or another. If you're doing it honestly, you can vote as often as you like.

[Interesting Ian]

166 votes. Hmmmm . . .doesn't look like they'll be many more. Certainly not going to get to 200. Revealing card tomorrow anyway.

"Anyway, I get no feelings about cards, so I just flipped a coin a few times. It came up heads 4 times, so I picked the first card in the list. I decided to keep flipping the coin to see how long it would take to get a tail. It took until the ninth flip." - 69dodge

"There's no point in voting if you're simply going to do that. This of course is another problem with the test which is beyond my control." - Ian

Ian, remember, that 69dodge's mind has already picked the card, and his psi abilities then control the coin so it matches up to the card already picked. So it's not random at all.

Well, as I said earlier, a single test means nothing. It's a pity you have chosen not to repeat the test. However, being totally honest, Ian, had the ten of clubs been on of the most frequently chosen cards, would you not be using this single test as anecdotal evidence of how psi works? I have little doubt that you would.

And such is the problem with anecdotal evidence for psi effects. You only hear about the anecdotes where it works.

Cool! :)

If ESP were real than it would have to be 100% accurate regardless of the number of trials! It doesn't matter what believers say about this because it will just be an excuse to disguise obvious coincidence! As always evidence for paranormal beliefs must be inline with any skeptical notions about how it should be! Like with reincarnation skeptics can say it's impossible because of population size changes! Believers might respond by saying that not everyone who dies reincarnates according to their beliefs! But this is meaningless because their explanation must account for how skeptics are viewing it or else its invalid!

Paranormal experiences are explainable by self-deception induced false memories being implanted after malleable brain states.

Only slightly tongue-in-cheek? I'll bet there is a part of you that believes it really was psi missing.

But your comment sounded exactly like all of the other claims you have made here. It is reasonable to expect that you would continue to make them. Of course, that's just anecdotal evidence. :D

It certainly could be. Many more tests would need to be carried out before we could come to any tentative conclusions.

To quote from Irwin's "An introduction to Parapsychology"



. . . Schmeidler established a trend for sheep (ie believers) to score above MCE (mean chance expectation) and for goats (ie skeptics) to score significantly below chance.

. . . . The result for goats is most fascinating. Not only does it confirm an effect on attitudes on the occurrence of ESP, it also reminds us of the adage that there are none so blind as those will not see. But the fact that goats' mean ESP score is significantly below chance suggests these people are not merely directing their attention away from extrasensory information nor blocking its cognitive processes; rather they seem to be identifying ESP targets at an extra-chance level and then unwittingly choosing a different target as their response. By making more incorrect responses than expected by chance, goats seemingly use ESP in a self-defeating endeavour to support their belief that ESP does not exist. . . . .

. . . . . The sheep-goat effect is one of the more successfully replicated relationships in experimental ESP research (Palmer, 1977), even if the overall effect size (0.03) is very small (Lawrence, 1993)


. . . . when she (Lovitts (1981) disguised an ESP test as a procedure for "disproving ESP," the usual scoring pattern was reversed, that is , sheep tended to perform below chance and goats showed psi hitting.

Let's all split the million. I'm content to share.

I said that I did not select my card at random. Here is how I selected it:

I selected the "least obvious" card.

When you ask people to name a card at random, they will usually name a spade or a heart, occasionally a diamond. Rarely will they name a club. Clubs are the "least obvious" suit.

When people are asked to name a value of a card, aces and face cards get named first, and very low cards get named next. Center cards (6s and 7s) get named next, with off-center cards being the least obvious.

On the list was one off-center club card: the ten of clubs. It was the "least obvious," i.e., it was the least likely to be named by people asked to "think of a card."

There are some magic tricks that are based upon this principle (and if you watch the reruns of David Blaine's specials, you will see him perform a trick using this principle). When you present a person with a group of a few cards and ask that person to "Pick a card that I could not possibly know," the spectator is more likely to select the "least obvious" card in the group. You can then reveal the least obvious card in any mysterious manner that you choose, and usually (but not always) the spectator will be left with the impression that you read his mind.

Maybe just emphasize the phrase "one of the more successfully replicated."

Forgot to say: the Resident Statistician here doesn't feel data from such an experiment can be analyzed because you can't know the real probability of any card's being chosen. They clearly don't all have a 1-in-10.

You could try to find out, running about a zillion trials with no target, looking for a baseline...testing suit agains position against number...
