What They're Saying

Critics Review

‘This book offers a wonderful blend of behavioral science, marketing acumen, and vivid storytelling. It demystifies the psychological drivers, cultural nuances, and situational influences that shape consumer choices every modern marketer must understand!’

– Jochen Wirtz, Ph.D., professor of Marketing and vice dean for MBA Programs * National University of Singapore *

‘We don’t buy things because of what they do. We buy them because of what they mean. Mehdi Bouhassoune shows us why. This highly readable history of consumer psychology should be required reading for research professionals. But it’s also fair game for those of us who are “consumer professionals”—in other words, anyone who has ever wondered why we buy.’

– Michael R. Solomon, Ph.D., professor of Marketing, Haub School of Business, Saint Joseph’s University

‘Mehdi Bouhassoune’s Why Did You Buy That Drink? masterfully retraces the development of marketing, linking foundational theories to current consumer behavior. Through clear examples, it examines how complex influences impact everyday purchases, providing an intriguing look at the science behind every sip, splurge, and purchase.’

– Pierre Chandon, L’Oréal chaired professor of marketing, innovation, and creativity, INSEAD; and director, INSEAD-Sorbonne University Behavioral Lab
