Could a Small Rule Change Behavior Without Changing Anyone's Opinion?
Systems often influence actions before they influence beliefs.
Yes. Behavior can change because incentives or constraints change, even when opinions remain unchanged.
A city introduces dedicated bicycle lanes. Some residents remain skeptical but gradually cycle more often because the route becomes easier and safer.
The hidden mechanism is behavioral adaptation. People frequently respond to changing environments without revising their beliefs immediately.
A micro-scene captures this effect: a commuter still complains about the policy while using it every morning.
Opinions explain what people say. Incentives often explain what people repeatedly do.
