Summary: This is a very weak book.
Review: This book reads more like an advertisement for the author than anything else. The author won't let you go through a chapter without reminding you that his team discovered important genes, such as "the gay gene." He even tells narratives about that fateful night he discovered gene FKDJU47, or whatever it was.The subtitle is misleading. To the completely ignorant, who do not believe genes have anything to do with behavior, it is true, but for everyone else, I'm not sure. Every chapter revolves around a specific personality trait, such as "Worry," "Addiction," "Sex," and "Hunger." He points out several specific genes and then after explaining them for several pages, points out that the gene only accounts for 2% of the variance in the trait. 2% isn't much. It turns out genes account for about 40-50% of most traits, but he doesn't seem to focus or care much about this. The conclusion is a fictional story about a doctor who clones himself, and discovers that the boy turns out little like the doctor. Seems like genes matter less than we think? Well, there's a mix here. Just like you should know! I gave this book 2 stars because there's nothing here that is "wrong." It's just a pretty bad read, in my opinion. I found myself skimming a lot but got through to the end, because it's fairly short and with titles like "SEX" I had to find out if there was something interesting. Turns out there wasn't! I don't know who I'd recommend this book to. Maybe someone interested in the real life drama of how Hamer and Copeland discovered gene A7483B8G7, which accounts for 0.238% of the variance in classroom tardiness.
