From: Chip Denman Subject: Geller and SRI Message-ID: <9209240049.AB15458@lll-winken.llnl.gov> Date: Wed, 23 Sep 1992 14:46:55 EDT "Information transmission under conditions for sensory shielding" by Russell Targ and Harold Putoff, both at Stanford Research Institute at the time, was published in Nature Vol. 251, October 18, 1974, pp 602-607. This was *the* paper that caused some people to think that Uri Geller's powers had been scientifically verified. It actually describes several different experiments primarily in "remote viewing"--i.e. extrasensory perception of visual targets. The paper addresses the alleged metal- bending powers of Geller only to say that "Although metal bending by Geller has been observed in our laboratory, we have not been able to combine such observations with adequately controlled experiments to obtain data sufficient to support the paranormal hypothesis." Really! They do describe experiments with Geller at "reading" drawings sealed in envelopes. Also mentioned is an experiment to guess the face of a rolled die. Some other experiments without Geller are also described. The bottom line--"...we conclude that: a channel exists whereby information about a remote location can be obtained by means of an as yet unidentified perceptual modality..." Randi and many others have strongly criticized the scientific rigor of these experiments. One of the most complete analyses can be found in The Psychology of the Psychic by David Marks and Richard Kammann, Prometheus Books, 1980. I have used the original paper and this book as a case study in a course I teach on science vs. pseudoscience. Those of us with a bit of conjuring experience can see plenty of opportunity for "sensory leakage" in what has been reconstructed of the actual experimental protocols. And it appears that the statistical analysis (my main expertise) of the non-Geller remote viewing experiments is severely compromised by the scoring methods used. Marks and Kammann attempted to rescore the results after removing subtle and not-so-subtle cues and --lo!-- the paranormal effect went away.

Gardner discusses this research, performed by Russell Targ and Harold Puthoff, in two articles: "Magic and paraphysics," which is most readily available in Gardner's collection _Science: Good, bad, and bogus_ (Buffalo, New York: Prometheus Books, 1981), and "The great SRI die mystery," which appeared in the Winter 1982-3 issue of _Skeptical inquirer_ and is reprinted in Gardner's collection _The new age_ (Buffalo, New York: Prometheus Books, 1988). ------ John David Stone - Lecturer in Computer Science and Philosophy ----- -------------- Manager of the Mathematics Local-Area Network -------------- -------------- Grinnell College - Grinnell, Iowa 50112 - USA -------------- -------- stone@math.grin.edu - (515) 269-3181 - stone@grin1.bitnet -------- From: Skeptics SIG Subject: Updates on Geller v.

To: broadcast-geller-hotline@ssr.com Hi folks! Things continue to improve. (1) Mr. G's lawyer in Florida (in the case he has against Prometheus, et al) faxed in a message recently, just 24 hours before a scheduled deposition of his client, saying that the deposee would not be appearing, (2) Mr. G has just made overtures in that case in the UK, suggesting that he would settle for a much lower award, and (3) I have Mr. G scheduled for a deposition in NYC on Feb. 2/93. Very soon, interesting things will begin to happen. Meanwhile, I have just signed another book contract. The present book, "Conjuring," has received excellent reviews (except for one magician who did not show up in the book) and in 1993 I will be appearing on at least two major, major TV programs that will feature the Geller saga. Another major TV news/investigative show will examine the Geller matter, as well. I'll be doing a major lecture tour in Australia in '93, too. So, great coverage is coming up and that can only end up going in the direction of unravelling this whole thing in our favor. I'm much encouraged. The ONLY down note is that The James Randi Fund is running low, and in need of a major transfusion. If anyone out there knows of an agency that might promote this cause, I'm ready to do some heavy listening.

To: broadcast-geller-hotline@ssr.com I've just been informed that Geller has entirely dropped the case against Prometheus et al in Florida. Just recently, he was saying he'd settle for $50,000 instead of millions, and now he wants to drop it all. Verrrry interesting! J.R.
