Description
The result is the most up-to-date, balanced, and engaging account of human sex differences yet written, covering everything from dating and mating to aggression and parenting, from children's toy preferences and workplace gender gaps to mental health and the politics of equality. Drawing on a century of research - and a billion years of evolution - Stewart-Williams explains why many sex differences appear despite socialization, not because of it; why in our mating and parenting patterns, humans are more like the average bird than the average mammal; and why sex differences are sometimes a sign of societal health rather than injustice.
With more than two decades of research in evolutionary psychology and an international reputation in the field, Steve Stewart-Williams is uniquely positioned to challenge prevailing views in this fraught debate. Avoiding the extremes of either overstating or denying the differences, he argues that, rather than trying to make men and women identical, we should strive for a world where bias and barriers are eliminated, and where people are free to be themselves whether they conform to gender norms or defy them.
Advance Praise
“Fearless, fascinating, and fair-minded… I can't think of a better book on the science of sex differences.”
~Professor Paul Bloom
“A terrific book – scholarly and anchored in the most current science, yet also highly engaging and readable for any audience. It’s sure to become a classic on the fascinating science of sex differences.”
~Professor David Buss, author of The Evolution of Desire
“Stewart-Williams explains, with authority and wit, how our evolved differences play out in dating, mating and parenting, and why facing these facts is essential for a fairer, more compassionate society. If anyone doubts the relevance of evolution to human behavior, hand them this book.”
