Interesting read, but biased in various ways. One of the problems with statistics is that a person can twist the numbers to make a point in the way they want.

Their authors do a good job of pointing out many of the gaps in arguments or inaccuracies in studies, but they still leave out others to benefit their arguments. It's frustrating and misleading.

That being said, the book still makes you think, though I fear not everyone sees the gaps.
