Cockroaches, Bridges, and Beer: The Weirdest Experiments in Behavioral Science

Aug 24, 2026 · 16m

Summary

Roger Dooley explores how behavioral science experiments isolate core principles using four studies: cockroach social facilitation, bridge arousal misattribution, Lego meaning, and price-placebo effects. He argues that effective testing requires stripping away noise to find the essence, exaggerating manipulations, and verifying results through replication. Dooley advises marketers to focus on underlying mechanisms rather than superficial variables to drive meaningful insights.
