" Unfortunately, this book was just too similar to _Freakonomics_ and especially to _Predictably Irrational_, with examples from marriages instead of other arenas. But the economic examples from studies, etc. were all familiar from the previous books, and although many of the marriage anecdotes were interesting, I didn't always feel that they really illustrated the economic principle that they were meant to.
