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

In this solo Brainfluence episode, Roger Dooley argues that the strangest-looking experiments in behavioral science are usually the most useful ones. He opens in 1969, when psychologist Robert Zajonc put 72 cockroaches through mazes in front of an audience of other cockroaches. That setup wasn't a joke. It was a precise piece of engineering: strip out self-consciousness, and you can finally see whether an audience by itself changes performance. The organizing idea comes from Dan Ariely, who describes a good experiment as a painting rather than a photograph. You don't reproduce every detail of the real-world problem. You capture its essence and build a tiny world containing that and almost nothing else. Roger walks through four studies built exactly that way: a swaying suspension bridge two hundred thirty feet above a canyon, a beer menu at a Chapel Hill brewery, a pile of Lego Bionicles, and an energy drink sold at two different prices. Each one carries a direct lesson for marketers and managers, from why people can't tell you why they bought something to why discounting can make a product objectively worse. The episode closes with four rules that separate experiments which transfer from experiments that produce a one-time winner, and a twist: fifty years on, someone re-ran the cockroach study, and only half of it survived.
