Illusory superiority

Also known as the the better-than-average effect · Self-assessment

Illusory superiority is the tendency to overestimate your qualities relative to others — to rate yourself above average on skill, ethics, and judgement. Statistically most people can’t be above average, yet most people believe they are.

Why it happens

We have privileged access to our own good intentions, judge ourselves on those while judging others on results, and define ambiguous traits in self-flattering ways.


'Above average' is a claim about half the population being below you — and they think the same.

Examples

  • Most drivers rating themselves safer than average.
  • The majority rating themselves above-average in honesty and intelligence.
  • Teams where nearly everyone believes they contribute more than their share.

How to counter it


  • Seek objective benchmarks and external feedback, not self-rating.
  • Assume you’re closer to average than you feel on most traits.
  • Judge yourself by results, the way you judge others.

The deeper point

It’s the engine behind Dunning–Kruger but broader: not just the unskilled overrating themselves, but nearly everyone, on nearly every desirable trait. "Above average" is a claim about half the population being below you — and they think the same.
