# Edgar Mitchell's ESP experiment

The followiing is from my review of *Entangled Minds* (EM), a sequel to Dean
Radin's 1997 defense of psychic phenomena* The Conscious
Universe* (CU).

**
the
Edgar Mitchell
ESP fiasco**

Another example of Radin's distorted history of psi research is his claim that astronaut and psi enthusiast Edgar Mitchell (1930-2016) conducted a "successful ESP card experiment from the Apollo 14 space capsule" (p. 76). Mitchell is a founder of the Institute of Noetic Sciences, where Radin is employed as a senior scientist. The experiment was unauthorized, so NASA did not set aside a nice block of time for Mitchell to conduct his experiment. News reports based on interviews with Mitchell indicate that he went through a hand-made Zener ESP deck several times while four friends on Earth tried to get psychic messages (either from Mitchell's mind [telepathy] or from the cards [clairvoyance]. Mitchell didn't use a Zener deck, however. He said:

The well-known experiment in the laboratory was to use cards with the five Zener symbols, but the actual cards aren't important. It was easier for me to use random number tables than carry the physical cards. Instead, all I did was to generate four tables of 25 random numbers just using the numbers 1 to 5. Then I randomly assigned a Zener symbol to each number. For each transmission, I would then check the particular table of random numbers and think about the corresponding symbol for 15 seconds. Each transmission took about 6 minutes.*

We know that there was a prearranged time when Mitchell and his
friends would do their trials, but that problems prevented
things from going as planned. As a result, the recorded guesses
on Earth were made *before* Mitchell went through
the trials. No problem. In his published paper on the
experiment, Mitchell just changed the goal to a study of
precognition!
(Mitchell's paper, "An ESP Test from Apollo 14," was published
in the *Journal of Parapsychology* in 1971.) He also stated
in an interview that the fact that the timing was off didn't
matter:

That didn't seem to make any difference. We took off forty minutes late but I didn't try for an exact time anyway, just in the evening. We now understand why that should work, because the sequence is important but having the precise time is not.*

This is fantastic
news for *psi*chologists. It means that in an ESP study one
can use data collected anywhere and any time to use as proof of
psi. How could you not like such a cooperative thing to study?

Original news reports
made it sound like there were 200 trials, leaving one to
conclude that Mitchell went through his tables eight times (there are 25
cards in a standard Zener deck). Since there are five symbols
(or numbers) in each table, chance guessing would be one of five, or 20%. Mitchell
reported that two subjects performed better than chance and two
performed worse than chance. What a shock! This is what you'd
expect from chance. News reports indicated that the group got 51
correct, which would be a hit rate of 25.5%, not bad for an
individual guessing 200 times, but not statistically significant
for a group of four. No problem. Mitchell provided the *New York Times*
with the number 3,000 to 1 as being the odds against getting the
results he got. Maybe this is where Radin learned to use
statistical odds as a substitute for evidence.

A closer look reveals this story is typical of the history of psi: much ado about nothing except manipulation and deception by the defenders of psi. Here is an abstract of Mitchell's experiment (S=receivers or subjects, E=the experimenter and sender):

Preflight arrangements were made with 4 Ss noted for ESP ability for a short "unofficial" experiment, to be carried out while the author, who served as the E, was on the Apollo 14 mission. On 6 different days the Ss were to guess the symbol order in 1 target run of 25 symbols being concentrated on by the E. Actually, E was able to carry out only 4 target runs, and the timing arrangements could not be met under flight conditions. The Ss, a, b, c, and d, made 6, 6, 1, and 2 runs of guesses, respectively, (a total of 15) to be checked against the 4 target runs brought back by E. The major problem was to determine, before checking, how the Ss probably oriented their efforts to guess the series of 4 target columns. Three independent analyses were conducted. In the 1st, the view was that as in a precognition test the sequence of 4 target runs on the record sheet would be the natural aim of the S. There were 8 runs (4 each by a and b) that could be checked by this plan; they gave a deviation of +11. The odds are 20:1 against chance. The 2nd analysis, initiated by E, aimed at determining the relationship between the guesses and the time proximity of the targets. There were 12 runs in this group (2 runs that overlapped were omitted) and these gave a very negative deviation having odds of 3,000:1. A 3rd analysis, also with below-chance results having odds of 25:1, followed an independent plan that cut across the other 2 analyses. The 1st 2 analyses, committed in advance, are independent of each other. The deviation in the 1st was positive, that in the 2nd, negative, indicating a psi-differential response by the Ss. This effect is further revealed in the reversed direction of distribution curves of hits within the runs for the 2 analyses.*

Cutting through the
gobbledygook, we find that the 3000 to 1 odds was derived by an
afterthought analysis of the data that found the subjects *did
not guess correctly*. Parapsychologists call this
psi-missing.
If you guess better than chance, that supports the psi
hypothesis. If you don't guess better than chance, that also
supports the psi hypothesis. Psi works both way, positive and
negative. Rather than canceling each other out, they reinforce
each other in what is called "a psi-differential response." What
other scientific field would tolerate such nonsense?

Why do I spend so much time chewing on this old rag? To emphasize to the reader that the claim by Radin that an experiment was "successful" or has been "replicated" in several labs should be taken with a quantum of entangled sodium chloride. (I know; there is no such animal. Allow me some slack.) This tactic of proclaiming success and replication, even though the claim never withstands scrutiny, works. Mitchell used the same tactic in an interview where he claimed that his experiment "did show that what had worked in the laboratory also worked in space with the same very positive results."* I've had several people e-mail me about Radin's claim regarding presentiment experiments, which he claims have been replicated in several labs, a sentiment apparently parroted by Alex Tsakiris on his podcast, Skeptiko.
