Why behavioural economics matters to a first-time founder
Behavioural economics studies how psychological, social and contextual factors shape economic choices. People use limited attention, shortcuts and habits, especially under uncertainty; that does not make them simply irrational. Founders can use these insights to understand pricing, onboarding and team decisions, while respecting customers’ autonomy rather than exploiting vulnerabilities.
Examples of behavioural economics
A Danish pension app tests two lawful enrolment screens. One requires users to choose a contribution rate before continuing; the other places the same options behind an optional link. More users make an active choice in the first version because the decision is clearer, not because their financial preferences suddenly changed.
Common misunderstanding
Behavioural economics does not claim that every person makes bad decisions or that classical economics is useless. It examines predictable departures from simplified models of perfect information and unlimited calculation. An observed pattern may also have several causes, so one experiment does not prove that a named bias explains all customer behaviour.
When to use it
Use behavioural economics when designing research, defaults, pricing displays, reminders or internal decision processes. Test the actual behaviour and disclose material information clearly. Avoid dark patterns, meaning interfaces that manipulate people into choices they did not intend. If a design mainly works through confusion or pressure, do not use it.
US spelling: behavioral economics.
