Horn Effect
The halo's mirror: one negative trait — an accent, a typo, a bad first meeting — corrupts the judgment of everything else.
An everyday example
Rejecting a strong proposal because the presenter was nervous.
What it can cost you
Losing good options to irrelevant flaws; being dismissed for one.
Warning signs
- One flaw and I stopped listening.
- I cannot name what else was wrong.
One thing to do
When a single flaw bothers you, name it and ask whether it predicts the outcome you care about.
