CORE DEFINITION

The cognitive bias of believing that an outcome was "foreseeable" after the fact—erroneously projecting post-hoc certainty onto pre-event uncertainty.

SCAFFOLDING EFFECT

psychology

Reduce cognitive load

Be wary of the false clarity of hindsight attribution. When evaluating past decisions, reconstruct the information state at the time, rather than judging with the benefit of current knowledge.

anchor

Anchor fast decisions

After the fact, the outcome seems "obvious in advance," and post-hoc certainty is mistakenly projected back onto pre-event uncertainty. The mechanism is "memory reconstruction"—once the outcome is known, the brain automatically rewrites its assessment of prior probabilities, creating the illusion of "I knew it all along."
