Query: He Could Have Done So Much Better

This book has no bibliography - first indication that it isn't meant to be taken *that* seriously. The thing that surprises me is that the author clearly did do some homework. Why, then, didn't he cite his sources? I have many of the studies to which he referred, so I know that the information he provided is peer-reviewed and accurate, but he presents it in such a way to negate it's importance.There are some typographical errors as well.If he had taken the time to work with an editor and to cite his sources the book would be not only an interesting read, but full of valuable information.I got the impression that he was more interested in getting a book published than in providing useful, accurate information. It's too bad, because it could have been so much more useful.
