In 1967 Edward Jones and Victor Harris had students read essays praising or attacking Fidel Castro. Even when told the writers had been assigned their side, readers assumed the essays reflected the writers' true views. Lee Ross named the 'fundamental attribution error' in 1977; it is also called correspondence bias. Everyday example: assuming a rude clerk is a rude person, not someone eleven hours into a double shift.
Why it matters
It distorts judgments of employees, tenants, leaders and fund managers, crediting or blaming character for what luck or circumstance caused.
Think of it like
Assuming a tenant who pays late is irresponsible, when a layoff or a bank error is the real cause.
The evidence
Replicated in many experiments since 1967 and reviewed by Daniel Gilbert and Patrick Malone in 1995. Cross-cultural work by Incheol Choi and Richard Nisbett found East Asians, including Koreans, weigh situations more readily.
Open questions
Because the bias is weaker in East Asian cultures, some argue it is not truly 'fundamental' but partly learned in individualist societies.

▸Fundamental attribution error is a core error in Social cognition: how we judge peopleWell replicated
The connection
The attribution error is the textbook example of a systematic flaw in how we read people: we see behavior and leap to conclusions about character, discounting pressures and constraints. Lee Ross called it 'fundamental' because so much social judgment rests on explaining others' actions.
Who showed it and when
Fritz Heider's 1958 attribution theory; Jones and Harris's 1967 essay study at Duke University; Lee Ross named it at Stanford in 1977.
The evidence
Replicated in many variations; Daniel Gilbert and Patrick Malone's 1995 review explained when it appears and why.
Open questions
Whether it is universal or culturally shaped, since East Asians correct for situations more readily, and whether 'error' is fair when traits do predict behavior.
▸Fundamental attribution error explains why people misjudge Milgram obedience experimentsWell replicated
The connection
Milgram's results surprise because people assume only cruel or weak people would deliver the shocks, overlooking the situation's pull. Psychiatrists predicted almost no one would go to the end. Even observers of a vivid re-enactment underestimated obedience and blamed the teacher's character.
Who showed it and when
Milgram's surveys of psychiatrists and students at Yale; Günter Bierbrauer's 1979 re-enactment study; Lee Ross and Richard Nisbett's 1991 book The Person and the Situation.
The evidence
Bierbrauer's observers kept attributing obedience to personality after watching a realistic re-enactment, a direct demonstration of the error.
Open questions
Later research found modest personality links to obedience, so the situation is not everything; how much character matters is still debated.
