hear or see his father "on the other side." Dawkins let the woman do the reading and at the end informed her that his father is alive, and he visits him frequently. Dawkins now visits a spiritualist church, and makes several criticisms of the alleged evidence of communication with the dead by medium Craig Hamilton-Parker, and adds that many may become obsessed with such performances and find it difficult to get over the loss of loved ones, adding that most people present are regulars. Hamilton-Parker says his psychic powers have been "proven to me against my rationality". Dawkins ends his study of séances by noting the arguments are based on untestable, private, subjective anecdotes, and compares this to religion. Dawkins now describes the history of scientific knowledge of echolocation, and points to the cumulative build-up of corroborating evidence for scientific explanations of the phenomena. He visits psychologist Chris French, who is performing a double-blind test of dowsing. None of the dowsers perform better, in a statistically significant sense, than is expectable by chance alone. While the dowsers are surprised, Dawkins and French note that their confidence is untouched, and they prefer explanations (French states some may call them excuses) that retain the hypothesis that they have paranormal dowsing powers. Dawkins next attempts his own explanation of belief in the paranormal in a combination of evolutionary and psychological terms, saying: "we don’t want to believe things just happen", and he suggests superstition is just the sort of animal error committed by Skinner’s pigeons. Dawkins now interviews Satish Kumar about ideas such as 'treeness' and 'rockness'. Dawkins points out that it is all evidence-free assertion. He responds to the "science is bleak" argument by saying that the world is so wonderful that the word 'mundane' has a mismatched meaning and etymology. He then complains about the long-term fall in the number of students taking chemistry and physics at A-level. He suggests this is partly because of the UK education system encouraging students to value personal feeling over evidence and reason. He interviews the relativist Steve Fuller and criticises him for being "so close to being right but ... damn wrong". Fuller points out that different people can interpret the same evidence differently. Fuller also points out the benefits of the Internet, and Dawkins agrees, but then turns to the dangers it poses in causing the spread of fabricated statements. He also points
