Question

A rare chemical spill scenario with catastrophic community impact is filed as low priority solely because it is rare. What evaluation mistake is this?

Accepted Answer

Using likelihood alone and ignoring that high consequence can still drive priority. — Rare and harmless are not twins. A long-shot catastrophe can still deserve serious attention. Do not let 'it almost never happens' erase how bad it would be if it did.

Answer
