The Hidden Instincts Behind Everything We Buy. Acclaimed psychologist Geoffrey Miller uses evolutionary biology to reveal how the dizzying, brand-satruated world of modern consumerism really works. In this original, provocative and witty book, Geoffrey Miller - author of 'The Mating Mind' - 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.
