#10: Don't make me get a restraining order.
Besides the creepiness, the book's psychological info doesn't extend much past a Psych 101 review of the Big Five OCEAN personality traits. It doesn't have much structure, either, instead existing as a series of vignettes on psych experiments; a chapter's stated thesis at the outset will often be forgotten by its end. (The author's admitted low score on Conscientiousness is no excuse.) Moreover, Gosling's often nasty to his subjects quick to label them as "nerds" and "prigs"; for a psychologist, he doesn't seem to like people much. (All right, I don't like people much, either, but I'm a bitter, cynical LJ poster, not an author who makes people his stock-in-trade.)
Anyhow: not very enlightening, and not recommended.
