Availability Heuristic

Your mind cannot continuously measure every risk, so it substitutes a cheaper question: How easily can I remember an example? Dramatic incidents produce sharp images, headlines, repetition, and conversation. That makes them easy to retrieve, and retrieval fluency gets misread as evidence that they are common or important. Slow harms and routine contributions generate fewer memorable episodes, so they receive less weight.

The same distortion works in reverse for progress. A bad incident can become a discrete story and travel widely; gradual improvement is dispersed across time and rarely produces a single moment worth forwarding. What fills your information environment therefore becomes a biased sample of reality, not reality itself.

The heuristic identifies a distortion in how importance is estimated; it does not prove that every dramatic event is trivial or that every slow trend matters more. A memorable incident may deserve attention. The error is treating memorability itself as the measurement.
