Princeton ESP Lab to Close

Nico M writes " The New York Times reports on the imminent closure of one of the most controversial research units at an ivy league School. The Princeton Engineering Anomalies Research laboratory is due to close, but not because of pressure from the outside. Lab founder Robert G. Jahn has declared, in the article, that they've essentially collected all the data they're going to. The laboratory has conducted studies on extrasensory perception and telekinesis from its cramped quarters in the basement of the university's engineering building since 1979. Its equipment is aging, its finances dwindling. Jahn points the finger at detractors as well: 'If people don't believe us after all the results we've produced, then they never will.'"

    The presence of the GCP is indicative of an overall human collective consciousness. Google it if you're not familiar, it's another Princeton based study, perhaps done by the same people, that shows some really interesting data indicating an overall change in random outcomes prior to any event that affects a large portion of the human consciousness as a whole.

    The World Trade Center attacks, Princess Diana's death, and other events with long lasting consequences brought large shifts in the outcomes prior to the events occuring - which is the most bizarre and interesting part. Other events, such as New Year's Eve, etc, also have results that are regularly shown. It's a positively enthralling study.

    Anyway, it suggests that we, as a whole, are projecting a field of human consciousness that affects random outcomes. This would suggest that any lone person attempting to affect random outcomes would be lost in the sea of thoughts, and have little to no overall effect.

    I am curious as to whether or not you could create some sort of shielding or better result by varying location, proximity, etc... The most interesting and telling experiment I can think of would be to take a human and a few random generators a great distance from the earth and resume tests. I had no idea that any really credible institute had been performing these tests, this is neat.

    1. There's no way they could possibly be unaware of the million dollar challenge, given their field of study.

    2. Winning the challenge would not only get them a million dollars in funding, but *incredible* publicity leading to millions more.

    3. They'd be crazy not to take the challenge if they knew they could win it.

    4. They haven't taken the challenge.

    Conclusion: They never discovered any repeatable paranormal phenomenon. Why am I not surprised?

    ... Unless, of course, demonstrating such a 'gift' resulted them in, oh, being burned at the stake as a witch, treated as the weird person up the street, or merely made it uncomfortable to be around people. Imagine if someone could read your every thought - do you think they'd stay in a relationship with you for long? What if mind reading makes people want to live alone - for the peace and quiet? What if foreseeing the future means that you don't want to hang around with people when you know how they're going to die? What if your subconscious also has telekenesis, so that dream of falling from the 13th floor can actually come true?


    I don't believe in these phenomena without evidence, but I can foresee ways in which revealing them could be detrimental to someone's chance at off-spring!

    The thing that gets me about the Randi prize, and indeed about any claim that attempts to prove the validity of psychics, is much the same argument that's brought up about magic in Harry Potter - do you really want to paint a gigantic target on yourself as the only scientifically proven psychic? Any true psychic (as well as anyone who reads celebrity magazines) would know what huge amounts of fame would do to them, and then you have the nutjobs who believe they're true psychics and would go to this person for self-validation and yadda yadda yadda. And then they get kidnapped by the CIA in order to fight terrorism.

    I mean, they're psychic. They know what will happen. And the only thing they get out of it is $1 million and a life forever ruined in the name of science.

    Come back when you've read the FAQ.

    I have. From the FAQ:

    1.4. How many people have passed the preliminary test?

    None. Most applicants never agree to a proper test protocol, so most are never tested.

    1.5. How many people have passed the formal test?

    No one has ever taken the formal test, as one must first pass the preliminary test.

    2.1. What do you mean by "mutually agreed upon"?

    "Mutually agreed upon" means that neither side can force the other side into doing or saying something that they don't want to, and that if no agreement can be reached, the application process is terminated, with no blame or fault attributed to either side.

    It's easy to point fingers after a Challenge claim comes to an impasse and say that the other side was being unreasonable. This phrase is used to insure that finger-pointing has no merit.

    Randi claims that most applicants never agree to a "proper test protocol", and are never tested. But he also points out that both sides have to agree what that "proper test protocol" is. So either side can basically tank the process by being disagreeable. With a million dollars on the line (not to mention his reputation), you have to believe that Randi has a serious incentive to make sure that nobody passes the test. Apparently the easiest way to do so is to ensure that nobody (or only a very few people) actually gets to take the test.

    Again, I'm not arguing that paranormal powers exist. I'm just pointing out that JREF's "Million Dollar Challenge" is little more than a publicity stunt, set up in such a way that they advertise a million dollars being available without ever having to pay out on it (or indeed, even attempt the challenge).

    I think that there was a software company is Russia that recently offered a similar challenge. Apparently someone was disputing their claims of being unhackable or uncrackable or something, and the company offerred a large sum of money to anyone who could break their software. The only catch was that you had to fly to Russia on your own dime, and use systems that they configured, and meet all sorts of other restrictive criteria that were specifically constructed to ensure that you could not succeed. The contest wasn't designed to prove anything, it was merely a way for the company to get some free publicity and advertise to perspective customers that "even when offerred x amount of money for demonstrating flaws in our software, nobody has yet been able to do so".

    Now if the criteria were set and judged by a neutral third party, then I might have a little more faith in the challenge. But I doubt that would ever happen because JREF would then face the chance (however minute) of actually losing the money and the bragging rights.

    Thanks, this has the 50-page paper I was looking for when I saw this story - I remember it from years ago: On the Quantum Mechanics of Consciousness, With Application to Anomalous Phenomen (1986). Foundations of Physics, 16, No. 8, pp. 721-772 (PDF). Now, the Foundations of Physics is not exactly a top-tier journal, but there is some very minimal peer review. The figures present some results that are, on the surface, somewhat surprising. For example, look at Fig. 2, p. 726. I suggested to CSICOP (the Skeptical Inquirer magazine, that I subscribed to) that they have some of their experts do a rebuttal, but even though I got a response that they'd take it under consideration, it apparently never happened. I am still puzzled by this paper.

  9. You didn't read it very carefully... by Anonymous Coward · · Score: 3, Interesting

    Well, if you check one of their papers, you'll find the following sentence, on page 7: "While no statistically significant departures of the variance, skew, kurtosis, or higher moments from the appropriate chance values appear in the overall data, regular patterns of certain finer scale features can be discerned." That's an outright confession of fraud. They are saying they cannot find any evidence if they analyze a statistically significant amount of data, so they pick whatever small sample will suit them. It's as if I threw a coin a million times and said: "Oh look! Here I threw ten heads in sequence!"

    No, wrong. They are saying there is no pattern in the HIGHER moments, but the CENTRAL claim of positive results that is presented in the paper is the statistically significant 7-sigma deviation of the MEAN when considering the entire set of data. This is not picking a small sample, it is considering everything and getting a consistent and extremely significant positive result. The rest of the paper is dedicated to seeing if there are any additional patterns, such as individual participants being more successful, and so forth.

    Further on, in the next page, they state "Given the correlation of operator intentions with the anomalous mean shifts, it is reasonable to search the data for operator-specific features that might establish some pattern of individual operator contributions to the overall results. Unfortunately, quantitative statistical assessment of these is complicated by the unavoidably wide disparity among the operator database sizes, and by the small signal-to-noise ratio of the raw data, ...", which means they didn't follow a consistent testing protocol and didn't have a standardized method for training their operators. Basically, they are admitting that any statistical correlation in their data is extremely small (which is what "small signal-to-noise ratio of the raw data" means) and they have no way to check if any positive results aren't attributable to insufficient training of their operators.


    This is a silly thing to complain about. First of all, training has nothing to do with experimental quality, because the operators have no physical contact with the device anyway, and thus can have no practical or theoretical influence except through a psi result. Training of operators can therefore only affect the strength of a result, and in fact, how to train operators to receive good performance is still a somewhat open-ended question. It's known that participants yield significantly stronger results after meditation, and that the beliefs and expectations of the participants correlate significantly with the successfulness of results. But neither one of these can invalidate a positive result, because NO training method for participants can produce a false positive, as there is no conventional physical mechanism by which a false positive can be obtained given their experimental setup.

    Also, having different operator database sizes simply means some participants participated in the experiment more often than other participants. This says nothing about the protocol, it simply says they were not trying to keep each participant limited to an equal number of runs. Critics who have actually visited that lab have failed repeatedly to find any specific problems with their experimental protocol.

    And "small signal to noise" does NOT mean that the data is too weak to draw conclusions, it only means that large datasets must be considered to draw statistical conclusions, and so it is not meaningful to consider very small datasets. Just above you were trying to accuse them of using small datasets, when in fact they are saying outright that they cannot use small datasets, and you are just failing to understand what they are saying.
