I was referring to the general area of parapsychology, including both the everyday variety (Houdini's "Miracle Mongers") and laboratory studies. For a discussion of possible ways of and evidence for cheating in lab studies, including labs involved in many of the Ganzfeld studies, see Blackmore's "In search of the light: The adventures of a parapsychologist." I will also admit to being influenced by an argument Blackmore attributes to Pierce (she discounts it herself) that it is easier to believe that cheating is going on than in true Psi effects, which are incompatible with so much of natural science. I see this as a kind of parsimony argument. > >Personally, I will never understand how someone of Bem's stature > >could participate in such a venture, nor how the editors of Psych > >Bull could permit such a fiasco. > > By your statement below, Bem and the editors of Psych. > Bulletin must obviously be both, credulous and naive. > > >Let us demonstrate humility about things that we truly do not > >know about, nor understand.

The most telling argument on this for me is the psychological one that I gave in the previous post. How many journals would publish some effect, even if it is significant, without the slightest hint of the _psychological_ mechanisms by which such behaviour could possibly occur? The perceptual, attentional, and cognitive processes that would be necessary to support such effects are simply implausible. On top of its psychological implausibility, the idea that objects or minds have emanations that communicate information that humans can process despite no physical evidence of the presence of such emanations stains credulity to the breaking point. The idea that strange features of the new physics might help, is dubious. Hooft, a physicist, writes in the Skeptical Inquirer, "there is _absolutely_no_way_ one can explain the paranormal in this fashion [i.e., via modern physics]" (emphasis is his). He lists as the _least_ likely explanation for paranormal phenomena "1. Hitherto unknown physical phenomena, implying paranormal transfer of information," followed in increasing order of probability by: "2. All phenomena are pure coincidences," "3. Psychic claimants are liars and charlatans, "4. A delicate psychological phenomenon, caused by wishful thinking," and "5. People can be tricked by their own brain." I would include methodological errors somewhere high up on the list as well. Another physicist, Stenger, is even more adamant (and less polite?), in a Skeptical Inquirer article title "Quantum quackery." He writes "Certainly no mystical assertions are justified by any observations concerning quantum processes." By pandering to misguided beliefs about the paranormal, psychology is adding to the all-too-many ways that we undermine our discipline's scientific credibility. Here is Hooft again: "Scientists are often accused of not being open enough to 'paranormal phenomena.' 'As scientists' they should be open to them, it is said. But it wouldn't be very open-minded if we wouldn't try to fit reported phenomena logically into the web of established physical phenomena and laws of nature. The laws of physics, biology, and psychology point all to the most plausible explanation of them all: paranormal phenomena are in the eye of the beholder. They happen between the human ears, not outside of them." The "But ..." sentence above needs a close reading; at least, I didn't catch its drift at first.
