I agree with the other reviewers who feel that Dr Wiseman is very much at the outright (scientific) sceptic end of the spectrum and there is no doubt in his mind that there is no such thing as the paranormal. And, in fairness, he makes his case well and for the most part backs it up with strong arguments based on solid research.
I also found this book to be a lighter, more humorous and overall a more enjoyable read than "The Luck Factor".
A key premise of the author's argument against the existence of the paranormal is that our minds are simply filling our deep rooted desire to have the comfort that belief in life after death may bring, and the hope that our humdrum lives may from time to time be touched by some form of magic. If you have restless nights caused by alarming and unidentified sounds from your attic / walls / basement, this book is likely to help you sleep easier. Personally, I prefer the thought that there are still some things that exist beyond our comprehension.
