Readers should be aware that some people interviewed in this book, including prominent psychologists, have written formal letters of complaint to the President of Norton (publishers of the US edition), stating that parts of the purported conversations are defamatory inventions. Other knowledgeable psychologists have stated that important elements in Slater's descriptions of important psychological experiments are erroneous. Even before I read these complaints by a number of prominent psychologists, I had reason to doubt the veracity of the author. From lengthy extracts in the Guardian newspaper in January, and lengthy excerpts from the book on BBC Radio 4 "Book at Bedtime" (five quarter-hour readings from different chapters), I formed the opinion that some of the author's accounts of her experiences, including passages in the alleged conversations she had with current psychologists, were very unlikely to be true. Likewise the detailed account of her first attempt at replicating Rosenhan's experiment concerning the diagnosis of someone who only pretended to have symptoms of severe mental illness seems to me to be largely a product of her imagination. I suggest that people impressed by enthusiastic reviews of the book, such as some of those posted here, should keep an open mind until they have had an opportunity to see the evidence adduced by critics of Slater's book.
