Some events have no frequency, no reference class, and no repeatable trial. The honest response is not a wider confidence interval — it is a different kind of answer.

prerequisite-of →Real uncertainty is not a casino — dice have known odds, life does not, and models built on games mislead exactly where it matters.Taleb's entire attack rests on this distinction, which Bernstein had already conceded via Knight and Keynes. Read this first and Taleb becomes a much more precise argument than a temperament.
← extended byWhen the reference class does not exist yet, ask which outcome is the default and what would have to change to get another.
A practical method for the unmeasurable case Bernstein identifies and leaves there. Instead of a distribution you cannot compute, produce a default plus an enumerated list of falsifiers.
← requiresRisk is a modern invention — for most of history the future was fate, and the idea it could be measured is only a few centuries old.You cannot ask which uncertainties are measurable until measurement itself exists as a category. The distinction is downstream of the invention.
