On rare, high-impact events, and why models built on the ordinary miss them.

The big ideas

Rare large events dominate outcomes in many domains, and they are absent from the data used to model those domains precisely because they are rare.

We construct explanations after the fact that make an unpredictable event look inevitable, which destroys the lesson that it was unpredictable.

The practical advice is about exposure rather than prediction: arrange things so the unexpected cannot ruin you, since forecasting the specific event is not available.

The distinction between domains where extremes are bounded (height) and unbounded (wealth, book sales, pandemics) determines which statistics even apply.

Practise it — no need to have read it

Take a plan of yours. Ask what single unlikely event would end it, and whether you could survive it rather than predict it.

A hint: The question is exposure, not probability.
