A Test for Sandsted

Is this the joke of the week section?

I don't know if it is or not. Go stand in front of a mirror and if it says Wednesday on your t-shirt or your forehead, then just maybe you are the joke of the week.

Certainly, you have my vote for joke of the forum.

;D ;D ;D LOL

BTW, the data we have is to 5 or 6 decimal places. You do know what a decimal place is don't you? No, it's not where you go to buy Decimals. ;)

If you truly want to see if Sandsted's claim of dowsing the dates is true or not, you should have a run of the test with Sandsted GUESSING the dates, then a run of the test with Sandsted dowsing the dates, so you will have something meaningful to compare it to.

Sandsted's claim is to dowse the dates of coins...not guess the dates of coins. There is no relevancy in Sandsted guessing the dates. That's kinda like asking a race car driver to drive a few laps slowly, just to make sure they are really racing when they drive fast. ::)
Excellent analogy, SWR.
 

Lets see now....One person doing the Contest...10 coins correct is 1 in 181.....So if the person is correct all ten times the results come out as 1 in 181.....He didn't beat the numbers you have come up with....Art

Here are the results of one analysis I did, taking into consideration that each individual date is really a range of 7 dates, with the exception of the dates at (or near) the extreme ends of the set S{40}. In this case, rather than using 1/40, I used 7/40. Pbsuccess = 0.175 And, I progressed the Pb as each trial was completed.

0 Correct, Pb .14606, 1 in 6.85
1 Correct, Pb .30983, 1 in 3.23
2 Correct, Pb .29783, 1 in 3.36
3 Correct, Pb .18037, 1 in 5.54
.
.
6 Correct, Pb .00551, 1 in 181
7 Correct, Pb .00094, 1 in 1061

(Note, these Odds are what could be expected from a Chance result, no dowsing involved)

Ohhhh, wait. You're blaming your mistake on someone going back and changing their post, right? Another one for the dowsing rule book!

Mmmm yes, 'accept that what I am saying is correct'? ;D Why, if you wish for us (or me personally) to accept what you say is correct, do you not wish to accept a statement of a dowser as correct? ;D :D ;) What do you think, anyone who dowses must by definition be a moron? Ye gads. ::) You fail to see a problem, between "average" guessing, versus the guessing ability of Sandsted. If you don't see that, then you are not as genius as you might think.

Oroblanco

Well, no..... I didn't start out thinking everyone that dowses was a moron, but............... when the compelling evidence is thrown in my face daily, it's hard to keep an open mind about that particular characteristic.

I'll say this ONE more time. Sandsted is NOT guessing the dates on coins. We already have precise data for "average guessing" (using your term). And, that data will be compared to his dowsing results, hopefully to evaluate if his dowsing claim is real or not.

Could you answer me a couple of questions?

1.) Why would Sandsted tell us he could dowse dates on coins, if in fact he was just guessing the dates?

2.) Have you had any exposure at all to a class, or problems concerning simple Probability axioms?

Ahhh, I see my suspicions are confirmed. You are certainly free and welcome to your own views and opinions, however be assured that you have ZERO idea of the education/intelligence level of dowsers, or are you a 'psychic' able to identify the exact IQ and education level of anyone, working from the internet as your 'crystal ball'? I will answer your two questions, out of courtesy - though I should simply ignore them as most skeptics seem to do to a whole host of questions posted by dowsers.

1: Why indeed, can you tell me why anyone makes any kind of statement on internet forums? I do not know Sandsted from Adam, or if Sandsted is even a human being, only see his posts. He could be a complete work of fiction, even created by a skeptic in order to make dowsers appear foolish by making extraordinary claims. He could be 100 percent honest and telling the gospel truth, I can not know since I do not know him and have never seen him demonstrate his abilities.

2:Are you truly interested in my education? Yes, I have had such classes, have you? For that matter, anyone who plays the lottery or gambles in a casino is going to get some exposure to odds ratios and chance.

Dowsers, I see no reason for us to continue to discuss this subject with self-important, conceited, scientific-pretender "skeptics" who seem to think all dowsers are of the lowest order of intellect possible. It is a waste of your time, and proves -nothing- since the phenomenon of dowsing is something that has to be witnessed to be believed. We are talking with people who judge intellect by spelling ability, who accept the theories of science as the pat answer for everything and only engage us in discussion in order to cast insults upon dowsers while setting up "tests" intended to "prove" that dowsing does not work, even though a serious study has already proven that it does work, for finding water. There is nothing to be gained by discussion with such self-appointed "skeptics". I for one, have other things to do.

Good luck and good hunting to you all, hope you find the treasure that you seek.

Your suspicions are confirmed? Not sure exactly what you are eluding to.... but I'm sure you must know.

Of course I would come here with ZERO idea of your education/intelligence level, or that of most anyone else here. However, through the course of several interchanges, one gathers a certain amount of information and can't help forming some opinions, just from things like spelling, sentence structure, and overall grasp of certain information imparted here. Naturally, anyone on the internet can hide their true intelligence by various intentional actions.... but then one must ask; why do that?

It seemed to me, after reading more than one statement (from you and others) that you were being very insistent, that Sandsted was going to be taking part in a test of his guessing ability. These statements were continued to be made, even in the face of several of the rest of us telling you point blank that it was NOT a test of guessing, and never was. I can't speak for the others, but in my case, when I see someone blatantly ignore point blank statements, and continue to make assertions contrary to what they've been told; ---it is hard to arrive at any other conclusion except perhaps there is some type of understanding impairment, and further rational discussion is pointless.

You answered question 1, with your own question, and some unnecessary narrative. The only reason I formed the question the way I did, is because I was trying to "learn" what your motives were for insisting that Sandsted would be guessing dates, instead of what I clearly understood, which was that he would be dowsing them. I'm sure many others had understood it the same way. You didn't explain your motives. NO, you have no way of knowing who Sandsted is, or any more about him than what you have been exposed to here ---the same as the rest of us. However, I took him(?) at face value and figured he was a dowser who had tested his talents on various items, one of which was dowsing the dates on coins.

I'm glad to know you have had exposure to Probability and Odds problems. Again, my only reason for asking that question was because after several here expounded repeatedly about the pre-calculated values for what could be expected from "random selection" --the issue was still pressed about having Sandsted do some "guessing" so we would have something to compare his dowsing to. Naturally, there is ZERO reason for this exercise since we already have the data and it will be used to make the most accurate comparison possible. When these facts were blatantly rejected; I (and others) were left with no other rational conclusion to draw, except perhaps we were presenting this information to person(s) who had never been exposed to basic probability and statistics tools. Ergo, ...my question.

I can see your point of view..... I hope you can see mine.

***Incidently, if you are going to play the lottery, or keno, it might be good if you have an understanding of Hypergeometric Distributions, not just odds and probability. :D

Wow Art, considering Carl's chart is posted in multiple places and you still managed to somehow link 1 in 181 with 10 successes is just mind boggling. The only conclusion is that you completely ignored it or you completely don't understand it. I guess that answers my question indirectly. I can't think of a single other conclusion one can infer from your post. No notecards for you Art...

Carl wrote: Why do you keep insisting that Sandsted's dowsing ability is equivalent to guessing? Do you simply not believe that he can dowse?

Ah, as usual you are putting words into my mouth. Your test is a guessing test, so why not call it what it is?

That depends on whether Sandsted can dowse, or not. If he can dowse, and choses to dowse the dates instead of just guessing, and is successful, then the test is not one of guessing. If you insist the test cannot be used for dowsing dates on coins, then please explain why it cannot be used for this purpose.

If you truly want to see if Sandsted's claim of dowsing the dates is true or not, you should have a run of the test with Sandsted GUESSING the dates, then a run of the test with Sandsted dowsing the dates, so you will have something meaningful to compare it to.

Again, that depends... do you believe that if Sandsted (or anyone else for that matter) guesses the dates, his results will not fall within an expected gaussian distribution as predicted by probability theory? If you believe his guessing would somehow be different, can you explain why you believe this?

I can't imagine how one could dowse the dates of coins, but cannot say if Sandsted can do it or not, considering that I have never seen it done.

One of the purposes of this thread was to elicit feedback from both skeptics and proponents. For the most part, the proponents have only complained that somehow the test is completely unfair, or that dowsing can never ever be tested. So here's an opportunity for you to think outside the box of preassumed failure...

If someone were to walk up to you and claim, "I can dowse the dates on coins," what sort of demonstration would you expect them to be able to perform, in order to convince you that they can, indeed, dowse the dates on coins?

Greetings Carl,

Carl wrote: That depends on whether Sandsted can dowse, or not. If he can dowse, and choses to dowse the dates instead of just guessing, and is successful, then the test is not one of guessing. If you insist the test cannot be used for dowsing dates on coins, then please explain why it cannot be used for this purpose.

How is it that you cannot see a problem with the test - for example, let us pre-suppose that Sandsted SUCCEEDS in dowsing more dates of coins than is probable by chance; how can you say that he "dowsed" the dates, and did not simply guess them, and got lucky? I don't mean to sound like Mr Skeptic, but really how could you KNOW that he had dowsed the dates, and NOT simply guessed? This is why I proposed that you run two sets of tests, using random coins from the batch each time (hopefully not coming up with the exact same dates in the same order) and have Sandsted GUESS for one set, then dowse the second set - if he were to succeed in dowsing the dates, you could then compare it to his success (or lack of it) by simply guessing. He might be just a lucky guesser, or have some intuitive abilities, simply comparing his dowsed results to the mathematical chance average only shows his success (or lack of) compared to chance, NOT whether he has demonstrated that his DOWSING resulted in a greater success.

Again, that depends... do you believe that if Sandsted (or anyone else for that matter) guesses the dates, his results will not fall within an expected gaussian distribution as predicted by probability theory? If you believe his guessing would somehow be different, can you explain why you believe this?

Personally I have no idea whether Sandsted will succeed OR fail at your test, as I have mentioned before (no offense here Sandsted) I really don't know Sandsted, and have never seen him demonstrate his dowsing of the dates of coins, nor of ANYONE ever dowsing the dates of coins. As I understand "dowsing" to be, it is not necessarily any kind of "paranormal" ability but shows some indications of being an ordinary electrical phenomenon, in which case the use of a pendulum/plumb bob over a map or chart of coin dates is not going to work, as the electrical charge of a coin is a relatively tiny electrical charge. Pendulum "dowsing" has many similarities to what is known as "remote viewing" and NOT any kind of electrical phenomenon, so WOULD require some sort of "paranormal" or "psychic" or ESP abilities, beyond those of the majority of the population. I sure wish Sandsted luck, and will get a chuckle out of this if it proves that he did it successfully (simply because of those extreme skeptics) I do believe that Sandsted's guessing WOULD be a different result from his dowsing of the dates, assuming that he actually dowses the dates. If they were identical or nearly identical, what would that tell you? If they were remarkably different, what would that tell you?

One of the purposes of this thread was to elicit feedback from both skeptics and proponents. For the most part, the proponents have only complained that somehow the test is completely unfair, or that dowsing can never ever be tested. So here's an opportunity for you to think outside the box of preassumed failure...

Somehow you seem to have concluded that I pre-assume failure of the test, when I have repeatedly pointed out that it is a SUCCESS which will be almost meaningless, without having some way to compare Sandsted's dowsing to Sandsted's guessing. I guess that you do not grasp this aspect, or want to lump Sandsted's dowsing with the mathematical average of the entire population, which shows virtually nothing about whether Sandsted had a different result by dowsing than he would have obtained by simply guessing.

If someone were to walk up to you and claim, "I can dowse the dates on coins," what sort of demonstration would you expect them to be able to perform, in order to convince you that they can, indeed, dowse the dates on coins?

I would ask to SEE IT IN PERSON, not trust to the mails and his word; as I have posted in several threads, repeatedly, dowsing is something that has to be seen to be believed you are NOT going to be convinced by anything that anyone can SAY about it.

Good luck and good hunting Carl, hope you have fun with the test.

Jean310 wrote: it is hard to arrive at any other conclusion except perhaps there is some type of understanding impairment, and further rational discussion is pointless.

Well Jean, perhaps there is some sort of understanding impairment, because saying something repeatedly "point blank" does not make it so. How many legs does a cat have, if we call the tail a leg? Four, calling the tail a leg doesn't make it a leg. ;D(A. Lincoln) If anyone here has an understanding impairment, you might look a bit closer to home. ;)

You have put words into my mouth, saying I have insisted that Sandsted is "guessing" yet I have repeatedly pointed out that we have NO way of knowing whether Sandsted dowsed OR guessed, in what anyone outside this forum would define as a guessing game.

Jean, your self-presumed intellectual superiority certainly has been well hidden, perhaps tucked away behind some of those barbs you like to toss? ;D I have mentioned this before, but you ought to know (assuming you are as well educated as you claim) flinging insults around shows us nothing about those you have insulted, but DOES show us something about you. ;)

You might have guessed this, but having studied a bit on odds ratios, I almost never play any lottery. Of course one cannot win if one does not play, but the odds of success are very long indeed. Good luck and good hunting to you Jean, no offense was intended and I hope that you find the treasure that you seek.

Wow! You are certainly not short on persistence. ::) The answer to that question is; because there are multiple trials covering a wide range of dates. 10 trials was not specified by accident, neither was the overall range of dates. ALL tests, that are designed properly, should be set so mere "guessing" and luck are a very remote possibility. (You can't get Randi's money with guessing.) And, as I've iterated countless times before, we already know, and have the data for random selection (guessing). I could go on.... but it's impossible to cram a textbook on probability theory into a single post.

Quite frankly, Oro, I could not care less if Sandsted dowses the coin dates, or guesses them. That is strictly up to him. The test is not being performed to discern that kind of information, though it could come out as a by-product. The test is strictly to see if the results will constitute some compelling evidence to support his particular dowsing claim.

Finally, I used the term understanding impairment merely because I find myself placing the same facts and information into multiple posts to the same person, and I do it repeatedly. Generally, when an instructor determines that one method of explanation is not working, they quickly realize they have a problem, and rephrase or approach THE SAME material from a different angle. When the instructor has exhausted the rational number of presentation attempts, and still certain individuals did not grasp the concept........... well, I think you can see where the fault must lie. ::)

Thanks for your input..........

...for example, let us pre-suppose that Sandsted SUCCEEDS in dowsing more dates of coins than is probable by chance; how can you say that he "dowsed" the dates, and did not simply guess them, and got lucky?

I've already covered this question, right here in this thread. A single, solitary test success can certainly be due to luck. I've mentioned Powerball as an excellent example of how individuals routinely get lucky. But I've yet to see the same person win twice.

So I will certainly admit that if Sandsted succeeds in this test that it could be due to luck. That's a possibility that is absolutely impossible to avoid. Going into this test, I knew that he might succeed by luck, and that such a success might then be used as absolute proof of dowsing. But with the persistent denials that there is any way to test dowsing, I thought it more important to demonstrate how an objective test is carried out. Not only that, but per Sandsted's requested threshold of success, the odds of him getting lucky are not overwhelmingly slim.

So what if he succeeds? How would you know whether it is by luck, or by powers of dowsing? Well, if you ran a single pre-test where he guesses, would that provide a reliable indicator? Absolutely not, because even if his "guess-test" was normal, it still provides no indication as to whether his "dowsing-test" success was due to dowsing, or guessing. It could still be a lucky guess. There is also the possibility that his "guess-test" is skewed to the lucky side, which creates an unrealistically high baseline to which his "dowsing-test" results are compared.

In science, anomalous outcomes happen. How does science normally deal with these outcomes? By repeating the test. If the anomally consistently shows up, then it is something real. So if Sandsted's initial results are successful, then the test can be repeated. If he is consistently successful, then it will indicate dowsing ability, and not guessing. I have already assumed that regardless of the outcome of this test, he probably would not agree to a repeat. But, like I said, I wanted to get folks to at least look at an example of objective testing.

He might be just a lucky guesser, or have some intuitive abilities, simply comparing his dowsed results to the mathematical chance average only shows his success (or lack of) compared to chance, NOT whether he has demonstrated that his DOWSING resulted in a greater success.

Randomized blind testing is designed to eliminate "intuitive ability." What's left, in the absense of a dowsing ability, is pure chance, which follows well-known probability theory. If dowsing works, it will have to be better than chance.

I do believe that Sandsted's guessing WOULD be a different result from his dowsing of the dates, assuming that he actually dowses the dates. If they were identical or nearly identical, what would that tell you? If they were remarkably different, what would that tell you?

What I really asked was whether someone's guessing would be different than that predicted by probability theory. I get the impression that some people believe random guessing does not really follow statistical distributions.

If someone were to walk up to you and claim, "I can dowse the dates on coins," what sort of demonstration would you expect them to be able to perform, in order to convince you that they can, indeed, dowse the dates on coins?

I would ask to SEE IT IN PERSON, not trust to the mails and his word; as I have posted in several threads, repeatedly, dowsing is something that has to be seen to be believed you are NOT going to be convinced by anything that anyone can SAY about it.

OK, let's say you are with them, in person. What sort of demonstration would you expect them to be able to perform, in order to convince you that they can, indeed, dowse the dates on coins?
