Testosterone Rex: Myths of Sex, Science, and Society

Are differences between men and women the result of evolution or biology, or are they influenced by societal development? Fine (psychology, Univ. of Melbourne; Delusions of Gender) attempts to answer this question as she reviews current research on sexual differences and the role of the brain. By examining how we have historically viewed sexual differences, the author presents findings that refute many antiquated theories. The book raises questions about the impact of testosterone, which many scientists have claimed is the key to this issue. Ultimately, Fine says, there is little compelling evidence suggesting that testosterone is responsible. In her final chapter, she notes that it's natural to ask about biological reasons for differences between men and women but then argues that we should instead be asking how it is that "men and women can so often behave similarly despite their biological differences." In the end, Fine states, "it's time to stop blaming Testosterone Rex because that king is dead." Written in a lively and accessible manner, this thought-provoking read includes valuable new information on the subject.
