Does this sound like the set of challenges you might be facing?

  • This person fits the picture in my head of exactly the type who’d do the thing, and I’m treating that as near-certain
  • Someone fits the picture of a type so perfectly that I just assume that’s what they are
  • I catch myself deciding who a person is from the group they belong to before they’ve done anything, and when they don’t fit I wave it off as them being the exception rather than questioning my read.
  • I size up a new idea against some image in my head of what its kind looks like and spit out a verdict
  • The story hangs together so neatly

Practices that may help

  1. The Representativeness Heuristic — Judging by Resemblance
    The representativeness heuristic is the mental shortcut of judging probability by how closely something resembles a prototype or stereotype. It is fast and often useful, but it reliably misfires when it overrides base rates, produces the conjunction fallacy, or treats random-looking sequences as unlikely.
  2. Interrogate whether similarity is doing the work
    When assessing probability or quality, ask whether you’re really judging similarity to a prototype.

  3. Look up base rates before forming a resemblance judgment
    Before deciding "this looks like X," ask how common X actually is in the relevant population.

  4. Audit person-judgments for prototype substitution
    Check whether a judgment about a person is based on their actual behavior or on resemblance to a type.

  5. Name the prototype you’re comparing against before deciding
    Make the prototype you’re using as a reference explicit — hidden templates bias decisions without scrutiny.

  6. Identify which features are actually diagnostic
    Separate features that genuinely differentiate categories from ones that just complete the picture.

  7. Treat small samples with explicit skepticism
    A short sequence can look representative without being statistically reliable — adjust confidence for sample size.

  8. The Affect Heuristic — When Feelings Substitute for Facts
    The affect heuristic, described by Paul Slovic and colleagues, is the tendency to use an immediate emotional reaction as a shortcut for risk and benefit judgments — things that feel good are seen as safe and beneficial, while things that feel threatening are seen as dangerous and costly. It is a fast and sometimes adaptive shortcut, but it reliably misfires when emotional salience and actual statistical risk diverge.
  9. Trust the recognition heuristic in uncertain environments
    If you recognize one option and not the other, the recognized one is usually better — in the right domain.

  10. Expect extreme results to regress toward average
    Unusually good or bad performance predicts more average performance next time — account for this before giving praise or blame.
