In this groundbreaking book Phil Barden reveals what decision science explains about people's purchase behaviour, and specifically demonstrates its value to marketing.

He shares the latest research on the motivations behind consumers' choices and what happens in the human brain as buyers make their decisions. He deciphers the 'secret codes' of products, services and brands to explain why people buy them. And finally he shows how to apply this knowledge in day to day marketing to great effect by dramatically improving key factors such as relevance, differentiation and credibility.
