Rational brain · Judgment & Decision Science

Halo Effect

A general impression — attractive, likeable, prestigious — spills into judgments of unrelated specifics, without awareness; the attractive candidate is assumed competent, the sleek product assumed reliable.

An everyday example

Rating a warm presenter's numbers as more accurate than a cold presenter's identical numbers.

What it can cost you

One trait filling in the rest; being managed through the trait that is easiest to fake.

Warning signs

  • I like them, so I trust their work.
  • One quality is doing all the judging.

One thing to do

Rate each dimension separately, in writing, with evidence for each, before forming an overall view.
