Pure pop psychology - interesting, but not too deep or scientific. It doesn’t seem like the author did any true research studies; it’s more of a collection of interviews and anecdotes. I didn’t mind; it makes for an easy read, and its pretty easy to see where you fit in too (I’m a Questioner, the second most popular group, after Obligers). The book’s true value is to show us how others react to expectations and to appreciate those differences.

3.5 stars.
