Fundamental attribution error
Explaining someone's behaviour by their character while under-weighting the situation they were in. You see the act, not the pressures that produced it.
What drives it
Character explanations are quick, feel predictive and let you stop thinking. They also keep you out of the frame: if he is lazy, you need not ask what you did to his workload. The situation is mostly invisible to an observer; the person is what fills the view.
How it shows
Work
A missed deadline becomes 'he's not committed'; a curt email becomes 'she's arrogant'. Reviews full of trait words (careless, political, not a leader) with no mention of workload, an unclear brief, a new boss or a sick child. Hiring and firing on one observed incident. The manager who explains his own late report by 'three fires at once' explains a report's late report by attitude.
Relationships
'You're so selfish' after a partner forgets something in a hard week. Friends' marriages judged on one dinner. Family members fixed in roles ('he's the irresponsible one') that ignore what each was carrying at the time.
Self
The tell is speed plus a trait word. If your explanation of someone arrived instantly, is an adjective about who they are, and you could not list three situational pressures they were under, you have probably made the error. Watch the asymmetry: your lapses get circumstances, theirs get character.
What tells it apart
Labelling: Labelling is the global, emotionally charged name-call ('he's an idiot'); the attribution error can be calm and reasonable-sounding ('she's not detail-oriented') and still ignore the situation.
Self-serving bias: Self-serving bias concerns your own outcomes, credit for wins and circumstances for losses; the attribution error is about how you judge other people and appears even when nothing is at stake for you.
Projection: Projection assigns someone a specific trait you disown, usually with emotional heat; the attribution error assigns whatever trait the act superficially implies, with no special link to your own conflicts.
A test
Before settling on a trait, ask what you would have done in their exact position with their information and load, then watch whether the behaviour repeats across different situations, since only cross-situational consistency justifies a character judgement.
Questions to carry
- Which pressures was this person carrying that day, and does the same behaviour show up when that load is gone?
- When I call someone lazy, what part did I play in the situation that made them look that way?
How strong the research is
moderate. The tendency to under-weight situations replicates well in Western samples, but it is weaker in collectivist cultures, and Malle's 2006 meta-analysis found the related actor-observer asymmetry close to zero.
