I have mixed feelings about this. I'm not an expert on research studies, but I have taken college courses on reading and analyzing them. The studies he picked seem biased and he interprets the data to support his believes, but the results have other meanings that he ignores. At times I felt like he completely misinterpreted data because he wanted more "evidence." Sorry, I don't have examples; I read this months ago. I don't regret reading it, but I'm just not in love with it. It's interesting enough for 3 stars.
