If you’re looking for proof of psi phenomena you won’t find it here. Instead, you’ll read a history of poorly designed research and questionable results. This is interesting in itself as an explanation of what constitutes good experimental design and what does not. Although the author describes several theoretical mechanisms that could explain psi phenomena, he also notes that only minimal evidence supports its existence.

 In his conclusion, Brian Clegg notes, “… coming at this with an open mind while frankly wishing that ESP did exist, I have to conclude that the existing experiments have demonstrated nothing more than coincidence, artifacts of the experimental design, misunderstanding, and fraud.”

Physicist, Wolfgang Pauli, became a good friend of psychiatrist, C. G. Jung. The two collaborated together on a book with each contributing a section. In Jung’s section, the psychiatrist describes what he calls synchronicity, a phenomena consisting of meaningful coincidences, and considered to be an acausal connecting principal. Pauli himself experienced a type of synchronicity as the jocularly known Pauli Effect. Reportedly, whenever Pauli entered a laboratory equipment malfunctioned. This occurred frequently enough that it became known as the Pauli effect. Jung’s synchronicity as well as Pauli’s Effect is largely based on anecdotal evidence and not achievable in a laboratory in the same fashion as cards in a deck can be guessed by experiment participants. Much traditional ESP research was conducted using a card deck of five symbols and evaluated by comparing the number the correct guesses to an expected twenty percent of the time. Often there is only a small deviation from the expected results.

Clegg feels that current methods of testing psi phenomena will never produce significant results. “What the researchers seem to have totally forgotten is that they are attempting to verify the validity of hundreds of years of anecdotal evidence. … Real-world ESP is not about small statistical variations; it is about clear, specific communication.”
