100 Things Every Designer Needs to Know About People

Design grounded in how people actually think and act.

by Susan Weinschenk

This book distills psychology and behavioral research into 100 short, practical insights about how people see, read, remember, decide, and act. Each entry pairs a research finding with concrete design implications for websites, apps, and products. It serves as a quick reference for evidence-based design choices.

Founders make endless product and marketing micro-decisions, and grounding them in real psychology beats guessing about what users will do. The bite-sized format makes it easy for a busy team to apply behavioral science without a research budget.
