Regret Aversion

The tendency to avoid actions that might lead to regret, even when those actions have higher expected value. Regret aversion makes people prefer inaction to action (errors of omission feel less regrettable than errors of commission) and conventional choices to unconventional ones (it's less regrettable to fail conventionally than unconventionally). The strategic insight: awareness of regret aversion helps you recognize when you're avoiding the right decision simply because the wrong outcome would feel more painful.

When to use it

When facing strategic decisions under uncertainty; when multiple stakeholders have competing interests; when the stakes are high and reversibility is low.
