The Science of Consciousness:
Chapter 17: Parapsychology
What this chapter is about: What is the evidence for parapsychological phenomena?
Paranormal phenoma are those for which there is no as yet physical explanation, and most scientists, particularly psychologists, would say that they don't exist. They include telepathy, clairvoyance, precognition, psychokinesis (together taken to be psi) and more fringe phenomena, such as ghosts.
Does anything of us survive after death?
I have given many talks on consciousness and parapsychology, and have been surprised how widely accepted paranormal phenomena are. A belief in the soul, ESP, and survival are maybe more common than not. Yet mostly scientists reject all of them, and psychologists are the most vehement in denouncing them. What accounts for this discrepancy?
My opinion on parapsychology: I'm sceptical, but remaining open-minded. I don't see any strong, robust, and replicable scientific evidence for psi. I also don't see a way they can be incorporated into our current scientific framework. But then I'm not wholly sure consciousness, particularly phenomenal experience, can either. And there are several physical and mathematical accounts of consciousness and psi that I don't understand and yet might ultimately be right.
If I had had much more space I would have made this chapter considerably longer. In the end though there are in my view two reasons for keeping it short: (1) most psychologists think there is no robust evidence for any paranormal phenomena, and (2) even if there were, what could it tell us about consciousness?
Survival and near-death experiences
This material now has its own page.
p. 389. "How spontaneous phenomena change with time. "At the turn of the century, spirts and afterlife ...": the phrase "At the turn of the century" is ambiguous - I'm referring to the turn of 19-20 th centuries.
Belief in paranormal phenomena
On p. 398 I say "virtually all psychologists think there is no evidence for psi". I think now this might be a bit of an overstatement. Personally I don't know any psychologists who admit to believing there is evidence, and I don't think my sample is too unrepresentative. I'd be interested in hearing about data on this. I have come across some claims that say that 34% of psychologists "believe that extrasensory perception is an established fact or a "likely possibility"; while not disputing this figure, it doesn't gel with my personal experience of psychologists, at least British academic cognitive psychologists.

In any future edition I would have a section on the prevalence of belief in paranormal phenomena in general. In the USA,
"a recent national poll found that over 71% of Americans believe in “miracles”, 42% of Americans believe that “ghosts” exist, 41% think that “extrasensory perception” (e.g., telepathy) is possible and 29% believe in astrology". (Scientific American, reference below).
