What This Is

Every day, marketers and product designers use well-researched psychological tactics to influence what you buy, how you decide, and what you click. These techniques come from academic research traditions — behavioral economics, social psychology, advertising science, and UX design — and they’ve been refined over decades.

This site documents plenty of these tactics in plain language, with real-world examples and the research lineage behind each one.
