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.

Is this happening to you right now?
