Why We Buy

Why We Buy is about the decision itself. Katelyn Bourgoin draws on behavioural science and buyer research to explain the psychology behind a purchase, then translates it into practice.

The research grounding is real, and she is careful about the difference between a robust finding and a marketing myth that has been repeated into apparent truth.

Strong choice if you want to understand customers rather than just optimise a funnel.
