If you didn’t write down the expectation, you can always explain the outcome.
That makes hindsight dangerously persuasive.
Once the result is known, assumptions get rewritten, uncertainty disappears and the story starts to look inevitable.
A simple discipline changes that: before an important decision, record what you expect, by when, what has to be true and what would change your mind.
Then you can compare reasoning with reality rather than narrative with hindsight.
Do you record expectations before major decisions, or mainly outcomes afterwards?
