Why do we buy? What is it that governs our choice of car? How does advertising really work? And what can the story of Aladdin teach us about today's world? In this brilliantly original, provocative and witty book, Geoffrey Miller takes us on a journey through the surreal wonderlands of marketing, advertising and media to explore the hidden instincts behind our choices. Combining this with the latest developments in evolutionary psychology, genetics and consumer research, he explains why we buy what we buy and how we can escape the excesses of twenty-first century consumerism.
