Testosterone, so we’re told, is the very essence of masculinity, and biological sex is a fundamental force in our development. Not so, says psychologist Cordelia Fine, author of Delusions of Gender. She explains that sex doesn’t create male and female natures. Instead, sex, hormones, culture and evolution work together in ways that make past and present gender dynamics only a serving suggestion for the future – not a recipe.
She brings together evolutionary science, psychology, neuroscience and social history to move beyond old ‘nature versus nurture’ debates, and to explain why it’s time to unmake the tyrannical myth of Testosterone Rex.
