Attribution Theory and Person Perception

A classmate walks in twelve minutes after the bell. The story that arrives first is careless. Last Thursday you walked in twelve minutes after the bell because the bus sat behind an accident, and that story felt like weather. Same lateness, two causes: a trait for them, a situation for you. Unit 4 is a hard-topic unit because those neighbors look alike on the page — fundamental attribution error is not self-serving bias, a stereotype is not a behavior, and a just-world idea is not proof that someone deserved a miss. The exam does not ask whether you are a kind person. It asks you to name the attribution you just made, and the one you skipped.

• Apply fundamental attribution error, self-serving bias, and actor–observer to a scene.
• Separate dispositional from situational causes.
• Do not turn a bias into a character insult.

An attribution is a cause you assign. Dispositional (internal) attributions point at the person: effort, skill, mood, ‘who they are.’ Situational (external) attributions point at the scene: traffic, the prompt, the weather, who else was there. The exam move is naming which kind of cause the observer used — not deciding whether the observer is a decent human.

Three related biases sit on that split. Fundamental attribution error (FAE): when explaining someone else’s action, we overweight disposition and underweight situation. Actor–observer: the same action gets a situational story when we did it and a dispositional story when they did it — we see our constraints; we see their act. Self-serving bias: successes get credited to me (disposition); failures get parked in the situation. Those three are neighbors. Mixing them is an expensive miss. FAE is about other people. Self-serving is about protecting a self-view across win and loss. Actor–observer is the self/other split on the same kind of act.

Person perception also loads extra color onto a first trait. Halo: one salient positive (or negative) feature spills onto unrelated judgments — a tidy slide deck becomes ‘smart,’ a tired face becomes ‘unprepared.’ Just-world is an idea, with limits: the belief that people generally get what they deserve. It can tidy a messy scene by blaming the person who was hurt. It is not evidence, not a moral license, and not a diagnosis of the observer.

Keep stereotype, prejudice, and discrimination distinct. Stereotype: a cognitive generalization about a group. Prejudice: an attitude, often negative, toward a group or a member because of that membership. Discrimination: behavior — a different act toward someone because of group membership. A thought is not a feeling is not an act. The exam will give you one of those three and a neighbor as a trap.

A missed pass in a match: ‘they don’t care’ (dispositional) versus ‘the sun was in their eyes’ (situational). A group-chat snap you sent after a bad night that you explain as exhaustion, while a similar snap from someone else becomes ‘rude.’ A first impression of a candidate with a polished voice that quietly upgrades every later answer — halo, not evidence. A news clip that treats a stranger’s misfortune as something they must have invited — just-world as an idea doing work, with a limit. A hiring screen that skips a name because of a group label is discrimination; a private generalization without that act is not the same term. Name the cause assigned. Name the neighbor you are not using.

Do not turn a bias into a character insult. FAE is a predicted lean, not proof that ‘people are stupid.’ Self-serving is a pattern of credit and blame, not a license to sneer at a classmate who used it. Halo is not ‘shallow people.’ Just-world is an idea that can distort blame — not a verdict that the observer is cruel. Pop posts that say ‘the fundamental attribution error means you should never judge anyone’ overcorrect; the exam still wants the name that fits THIS scene.

Scenario

Kenji’s teammate airballs a free throw in a packed gym. Kenji thinks, ‘no focus.’ When Kenji airballs the next one, he thinks, ‘the crowd and the lights.’ Which pattern best names both halves, and which neighbor should you reject?

Walkthrough

Same act, dispositional cause for the other person, situational cause for the self. That is actor–observer. FAE could describe the first half alone (overweighting the teammate’s trait), but it does not, by itself, name the self/other split. Self-serving would need a win credited to the self and a loss parked in the situation — here both shots are misses, so the win/loss pattern is not the engine. The move is the name that covers both halves without insulting Kenji.

The move

Actor–observer: situation for self, disposition for the teammate. Not self-serving (no success to claim), and not a character verdict.
