this was a quick and easy read. it was written to be popular with the masses, so it was "witty", and had basically zero references to anything that might have backed up the bold claims made in it. it did have an extensive list of studies and articles at the back of the book, but that doesn't really tell me anything. i do find this topic really interesting though, and plan on reading up on it more. hopefully the next book will succeed a little better in convincing my inner sceptic, as well.
