What is attribution theory?
An attribution is a judgment about why something happened. When a friend shows up late, you might decide they are careless or that traffic was bad. Attribution theory describes how people make these causal judgments and how the judgments shape emotions and behavior.
- Key figures
- Fritz Heider (1958), Harold Kelley, Bernard Weiner
- Core idea
- People act as "naive scientists" explaining behavior
- Basic distinction
- Internal (dispositional) vs external (situational) causes
- Classic biases
- Fundamental attribution error, actor–observer bias, self-serving bias
Heider: internal and external causes
Heider called ordinary people naive psychologists. We locate causes either inside the person (internal: personality, ability, effort) or outside (external: situation, luck, task difficulty).
Kelley’s covariation model
Kelley proposed that, when we have repeated observations, we weigh three kinds of information. Example: "Sam fell asleep in calculus today."
| Information | Question | Example |
|---|---|---|
| Consensus | Do others do it too? | Other students also dozed off |
| Distinctiveness | Only in this situation? | Sam stays awake in other classes |
| Consistency | Every time in this situation? | Sam dozes in every calculus class |
High consensus, high distinctiveness and high consistency point to the class ("calculus is boring"); low consensus, low distinctiveness and high consistency point to Sam ("Sam is always tired").
Weiner’s achievement attributions
In education, Bernard Weiner’s model is the most widely used. Causes of success or failure vary on locus (internal/external), stability (stable/unstable) and controllability.
| Cause | Locus | Stability | Controllability |
|---|---|---|---|
| Ability | Internal | Stable | Uncontrollable |
| Effort | Internal | Unstable | Controllable |
| Task difficulty | External | Stable | Uncontrollable |
| Luck | External | Unstable | Uncontrollable |
Students who blame failure on effort or strategy tend to try harder; those who blame low ability tend to give up, which links attribution to learned helplessness. This is also why growth-mindset style feedback praises process rather than talent.
Common attribution biases
- Fundamental attribution error: overestimating personality and underestimating situations when explaining others’ behavior (Ross, 1977). In Jones and Harris (1967), readers judged that essay writers held the views they wrote even when told the position was assigned.
- Actor–observer bias: "I was late because of traffic; you were late because you’re disorganized."
- Self-serving bias: crediting success to ourselves and blaming failure on circumstances.
Attributions matter in courtrooms and HR offices too. Whether an accident is seen as a careless person or an unsafe system can change how blame, discipline and liability are assigned.
Using attribution theory
- Praise students for strategies and persistence, not "being smart."
- When a colleague makes a mistake, ask about situational factors first.
- Frame your own setbacks as specific and changeable.

Frequently asked questions
- What is the difference between internal and external attribution?
- Internal attribution explains behavior by traits, ability or effort; external attribution explains it by the situation, luck or task difficulty.
- What is an example of the fundamental attribution error?
- Assuming a driver who cuts you off is a rude person, without considering that they might be rushing to a hospital.
- Which attribution is best for motivation according to Weiner?
- Attributing failure to internal, unstable and controllable causes such as effort or strategy is most likely to sustain motivation.
