Bias Blind Spot

Seeing biases clearly in other people while believing your own judgment is the exception — a bias about biases.

Examples

Jonas: “My uncle only watches one news channel. Totally brainwashed.” Mira: “What do you watch?” Jonas: “I follow sources that actually get it right.”

Jonas can diagnose motivated reasoning at fifty paces — in his uncle. His own sources “get it right”, which is precisely what the uncle would say.

In studies, an overwhelming majority of people rate themselves as less biased than the average person — while cheerfully agreeing that the average person is quite biased. Reading a list of biases (like this site) doesn’t dent the pattern: people nod, recognize their friends and opponents in every entry, and exempt themselves.

The uncomfortable punchline from the research: being smart doesn’t help. Cognitive sophistication shows no protective effect — sharper reasoners are, if anything, slightly better at explaining why the bias doesn’t apply to them.

Why it happens

You detect bias in others by their behavior: what they read, whom they excuse, where their conclusions land. You assess your own bias by introspection — you look inside for the feeling of being unfair, find none, and acquit yourself. But bias doesn’t feel like anything from the inside; skewed reasoning presents itself as ordinary good judgment. The check most people run on themselves is a test that biases pass by design.

There’s a second sting: knowing about biases becomes ammunition. It’s tempting to use this site as a scope for hunting other people’s errors — “that’s confirmation bias, that’s sunk cost” — a move that drifts toward ad hominem while your own reasoning goes uninspected.

How to counter it

  • Judge yourself by behavior, not by feeling: track what you actually read, share, and concede. Outputs, not intentions.
  • Adopt procedures that don’t ask how fair you feel — write predictions down, blind the author’s name, define the yardstick in advance.
  • Invite a specific critic: “What am I not weighing here?” from someone unlike you beats a week of introspection.
  • Apply every entry on this site to yourself first. That’s what they’re for.
