Chocolate ice cream or vanilla? A Ford or a Honda? When we make choices like these, our decisions feel free, but this book highlights research in psychology that reveals how powerfully our behaviour is determined, even when it feels free. It explores the fascinating evidence, Including why we find some men and women more sexually attractive, why some become criminals or psychopaths, and even why some are more likely to believe in God. The book concludes with a discussion of the profound - and sometimes counterintuitive-implications. If all behaviour is determined, for example, this might seem to leave us helpless in the face of the environmental and genetic forces that control us, but Lieberman argues that determinism potentially allows us greater control over our behaviour than free will, not less.
