Perfect for you if...

  • You're curious about the science behind morality and want to understand what actually drives human behaviour beyond pop psychology platitudes.

  • You appreciate wit and accessibility in science writing. Sapolsky makes complex neuroscience genuinely entertaining.

Maybe not for you if...

  • You're looking for a self-help book with actionable steps to change your life. This is pure understanding, not practical application.

  • You want simple answers. Sapolsky's central argument is that human behaviour is wildly complicated and determined by countless interacting factors.

About this book

New York Times bestseller • Winner of the Los Angeles Times Book Prize • One of the Washington Post's 10 Best Books of the Year“It’s no exaggeration to say that Behave is one of the best nonfiction books I’ve ever read.” —David P. Barash, The Wall Street Journal"It has my vote for science book of the year.” —Parul Sehgal, The New York Times"Immensely readable, often hilarious... Hands-down one of the best books I’ve read in years. I loved it." —Dina Temple-Raston, The Washington PostFrom the bestselling author of A Primate's Memoir and Determined: A Science of Life Without Free Will comes a landmark, genre-defining examination of human behavior and an answer to the question: Why do we do the things we do? Behave is one of the most dazzling tours d’horizon of the science of human behavior ever attempted. Moving across a range of disciplines, Sapolsky—a neuroscientist and primatologist—uncovers the hidden story of our actions. Undertaking some of our thorniest questions relating to tribalism and xenophobia, hierarchy and competition, and war and peace, Behave is a towering achievement—a majestic synthesis of cutting-edge research and a heroic exploration of why we ultimately do the things we do . . . for good and for ill.
