I'll let you in on a secret - Fine's book isn't actually about whether or not sex differences exist.

Here, in her introduction: "There are sex differences in the brain"

Instead, this is a book about how we seek evidence for sex differences, how we interpret and employ that evidence.

You can read it as a case study of how psychology is done in areas where we all have strong intuitions (that is, most areas of psychology)
