Self-help ✦ Penny’s Take
The Nurture Assumption
Judith Rich Harris · 1999
78/100
👍 Worth It
Judith Rich Harris wrote one of the most genuinely paradigm-rattling books in popular psychology, and it earned a Pulitzer finalist nod and a Steven Pinker endorsement for good reason. The central claim — that parents barely matter to personality beyond genetics — is almost certainly overstated, as subsequent research has shown, but it sparked real scientific debate and reshaped how researchers think about peer influence. Read it as a bold provocation rather than settled science, and it is enormously rewarding.
