I found this blog by this guy Louie Savva who has nearly finished his PhD thesis on parapsychology from an evolutionary perspective. He has a blog entitled Everything is Pointless which is truly comprehensive.
He has an entry entitled "Why I quit Parapsychology" which is enlightening and reminiscent of Susan Blackmore's switching to the dark side.
At the beginning of my PhD I would describe myself as very much convinced by the empirical and anecdotal nature of psi (and specifically the body of evidence suggestive of precognition) although there was a great deal of parapsychological research which I was willing to dismiss outright (such as much of the survival research).
Employed for one year researching the ganzfeld effect, I had an opportunity to work on what is often declared the best evidence for parapsychology and at the same time conduct a range of other parapsychological investigations, including helping to develop a precognition test using visual-noise .
None of the spontaneous or evidential claims of the paranormal have ever impressed upon me a need for recourse to a paranormal explanation and in fact the very obvious is apparent; that any connection between events in our mental life can tally, with shocking coincidence, so much so, that those who are prone to magical thinking believes has a paranormal basis.
Finally, I had intended not to write up my PhD, in the light of the fact that there seems no apparent audience. The parapsychologists will continue to ignore null findings (on the basis already discussed) and the sceptics will say ‘so what’. I was finally motivated to finish it, in the hope that I might dissuade others who are interested in the question of the paranormal, from pursuing it any further.
