The feeling of inevitability
Hindsight bias is the tendency to remember an uncertain event as more predictable than it really was. Knowing the outcome changes how we arrange the evidence in memory.
A useful archive should restore the old uncertainty. That is why our scenarios use a cutoff date and hide later facts until after the choice.
What it does to a story
It turns a risky bet into an obvious bargain, a reasonable sale into cowardice, and survival into proof that failure was never possible. The correction is not to pretend outcomes do not matter. It is to put the risks back into the frame.
