Fundamental Attribution Error, explained.
The fundamental attribution error describes overweighting personal dispositions relative to situational influences when explaining others’ behaviour.
Why it happens
A fictional quizmaster scores six out of six and a contestant two. Revealing random role assignment and private question selection supplies situational information; the reader can revise an ability rating.

Read the result
The revised rating belongs to the reader. The interface does not choose how much the role information should change it.
A worked example
The quizmaster’s hidden advantage
Rate the quizmaster’s ability using the initially visible six-versus-two performance comparison.
Inspect the randomly assigned roles and the quizmaster’s control over private questions.
Record a later rating and identify what the score does and does not reveal about underlying ability.

Inside this model
A fictional quizmaster scores six out of six and a contestant two. Revealing random role assignment and private question selection supplies situational information; the reader can revise an ability rating.
Where this idea is useful
A practical use
Before interpreting a colleague’s outcome as talent or laziness, inspect the opportunities and constraints built into the role.
A common misconception
“A better score always proves greater underlying ability.”
An outcome can reflect ability, opportunity and task design. A role advantage can change the evidence supplied by a score.
What this explanation leaves out
- Scores and role constraints are stipulated; a changed rating is recorded rather than forced or labelled correct.
Must I reduce my ability rating?
No. Your judgment is recorded without a prescribed answer; the useful step is considering the revealed situational constraint explicitly.
Who had control over the task that produced the result you are judging?
