A recent and more critical analysis of Bem's work still improves the odds, but only slightly (below). Of course, depending on whether you favor or disfavor something, with or without industrial and socio-political motivations, you can always keep looking for different approaches to employ that might shift interpretation of research data one way or the other.
"According to Rouder and Morey, in order to accurately assess the total evidence in Bem's data, it is necessary to combine the evidence across several of his experiments, not look at each one in isolation, which is what researchers have done up till now. They find there is some evidence for ESP – people should update their beliefs by a factor of 40." http://medicalxpress.com/news/2011-05-odds-esp.html
Most the complaints thus far seem to have done precisely that--focused on one study in isolation from all the others and particularly on the 53% success rate. "53%! Why I do THAT well on the slot machines occassionally!" I'm pretty sure these scoffers are untrained in statistical evaluations of scientific data. While 53% sounds insignificant to laymen, it in fact is about the rate that other experiments on the bad health effects of various chemicals and drinks are taken as good evidence. So that fact, taken with the evidence of the other 8 experiments, definitely says these results merit serious consideration and future attempts at replication.
I found these observations interesting:
"It's craziness, pure craziness. I can't believe a major journal is allowing this work in," Ray Hyman, an emeritus professor of psychology at the University Oregon and longtime critic of ESP research, said. "I think it's just an embarrassment for the entire field."
Hyman is right but for the wrong reasons, for self-serving reasons, which makes him wrong.** And the NYT assertion that this "accentuates fundamental flaws in the peer review of research in the social sciences" is also wrong, wrong, wrong, wrong.
There's a subtlety to the experiments that is indeed explicit in the articles but is easily overlooked, so I'll quote from the study:
From the participants' point of view, this procedure appears to test for clairvoyance. That is, they were told that a picture was hidden behind one of the curtains and their challenge was to guess correctly which curtain concealed the picture. In fact, however, neither the picture itself nor its left/right position was determined until after the participant recorded his or her guess, making the procedure a test of detecting a future event, that is, a test of precognition.*
This is the part that's important.* If it was a study of clairvoyance, well, could there be a possible physical explanation?* Perhaps.* But time travel?
Which is why anyone who says this study* "doesn't belong in a scientific journal" is wrong.* It doesn't belong in a psychology journal: this is an experiment about the laws of physics, not the laws of psychology.*
And so to say that* it is a failure of peer review-- like they did with Wakefield--* also misses the point. * Bem's peers are in absolutely no position to review this.* This study is better reviewed by physicists.* Bem himself makes an explicit case for quantum entanglement!* So notwithstanding my own rants about peer review,
"Four reviewers made comments on the manuscript," [said the journal's editor] "and these are very trusted people."
Trusted though they may be, they are not experts in the field being studied.*
All four decided that the paper met the journal's editorial standards, [the editor] added, even though "there was no mechanism by which we could understand the results."
Exactly.* So you should have sent it to the physicists.* You know, the ones who work a building over in the same university that you do.* That was the whole reason for universities, right?*
No, I'm a dummy.* The purpose of universities is to suck up Stafford loan money.* And the purpose of journals is to mark territory, more money in that, like a corporation that spins off a subsidiary.* NO CROSS SCIENTIFIC DISCUSSION ALLOWED IN SCIENCE, EVER, EXCEPT IN SCIENCE, NATURE, AND THE POPULAR PRESS."====
