A lot of the same tired arguments are trotted out when equality for women is discussed, and right now they tend to boil down to the same things: We've done enough; women can get those better jobs if they _really_ want them; and we can't fight Human Nature.This book attacks the premise that men are dominant in the workplace and the world because of the Almighty Testosterone, and it doesn't throw evolutionary biology out the window while doing so. Instead, a picture is painted wherein behavior is influenced by a complex combination of adaptive genes, hormones, and developmental environment.The most interesting bit to me was when she picked apart the studies on male and female behavior and pointed out how they were poorly designed, and how way too much was extrapolated from somewhat less than impressive data.I worry this book will bounce right off the people it's intended to debunk though- it even states at one point that it's easier to say testosterone = male superiority and call it a day than it is to examine the huge network of environmental and social factors that drive gendered behavior.Still, it was a worthy effort and an interesting read.
