“This brilliant book is without a doubt the very best exposition on our genes, how they influence quite literally everything about us, and why this means we should care more, not less, about the societal structures in which we live.”—Angela Duckworth, author of Grit

“To me, the aim of genetic research should be threefold: to find out which differences between people are real, which of those matter, and how to use that knowledge to get the best outcomes for all people. This fascinating book is a step toward that goal.”—David Epstein, author of Range

“Harden expertly explains what we can—and importantly, can’t—take away from genetic research, and does so without shying away from the complexities or controversies. Nobody should be allowed to opine about genetics in public until they’ve read this book.”—Stuart Ritchie, author of Science Fictions

“A thoughtful, brave, and very engaging book. In contrast both to those who see genetic differences as justifying hierarchy and to those who reject the study of the influence of genes on social stratification, Harden argues that understanding the findings of behavioral genetics is essential if we are to create a more just society.”—Peter Singer, Princeton University
