The website for Psychology Today has freely released an article from the July/August 2000 issue, titled “Is There a Sixth Sense?“. The article is a piece written by Dean Radin, author of the brilliant book The Conscious Universe (Amazon US and UK), which is also replied to by noted skeptic/cynic Ray Hyman. Radin focuses mainly on his precognition experiments in the essay – I recommend a read as it’s two of the ‘heavyweights’ of parapsychology research and the skeptical community head-to-head.
