The surprising science behind everyday purchases

Why Did You Buy That Drink? unravels the fascinating science behind our everyday purchases. We all make decisions, knowingly or unknowingly, about what to buy on a daily basis. These decisions seem insignificant – they're about sodas and paper towels – but they do hide more science than is originally apparent.

This book sheds light on these hidden forces at play—from the meanings we attach to brands, the impact of timing, and how our brains filter information, to the roles our beliefs and social circles play. By diving deep into consumer research and dissecting these ordinary choices, the book invites everyday life into scientific laboratories.

Why Did You Buy That Drink? challenges you to ponder over the daily battles ultimately shaping your life. It offers eye-opening insights that are set to forever alter how you view your receipts.
