CORE DEFINITION

Refers to events that have a very low probability of occurrence, but if they occur, have a huge impact, and to some extent are foreseeable (not completely unpredictable, i.e., not black swans).

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

It fills the gap in black swan theory. It reminds us that many disasters are not completely unpredictable but are ignored. We should develop specific contingency plans for risks that are 'low probability, high impact' and have discernible traces.

Anchor fast decisions

Proposed by Taleb in addition to the 'black swan', it refers to events that 'may happen, have huge impact, but whose calculable risks are overlooked by the mainstream'—more predictable than black swans, yet still impactful due to neglect.
