Expectations change how the same experience feels.
More quotesIn Fischhoff’s experiments, learning which historical outcome occurred changed what participants believed they would have predicted beforehand.
Once the outcome arrives, the route becomes suspiciously straight. Ambiguous clues acquire arrows. Dead ends disappear. Memory upgrades “possible” to “probable” and “I had a funny feeling” to a full strategic forecast.
A campaign succeeds and every choice joins the winning formula. A hire struggles and one odd interview answer becomes the warning everybody remembers spotting. The market falls at noon; by tea, three commentators have always known it would.
This wrecks learning because outcomes and decisions are different objects. A stupid bet can win. A sensible bet can lose. Judge everything by the result and luck receives a promotion while uncertainty gets blamed on intelligence.
The only decent witness is a record made before the reveal. What outcomes seemed possible? What probability did each deserve? Which assumptions mattered? What would have changed the choice?
Later, compare process with information genuinely available at the time. Notice which details gained meaning only after the event. Preserve the alternatives that never happened; their disappearance is the trick.
Months later, the written probabilities may look embarrassingly uncertain. They also show what was genuinely known on the date, including the outcomes nobody now remembers discussing.
