fundamental attribution error

The fundamental attribution error is a concept in psychology that describes a common tendency in how people explain behavior. It suggests that when observing others, individuals tend to overemphasize internal, dispositional factors (like personality traits) and underestimate the influence of external, situational factors. For example, if someone cuts you off in traffic, you might assume they are a rude person (internal attribution) rather than considering they might be rushing to an emergency (situational attribution).1

This contrasts with how people often explain their own behavior, where they are more likely to cite external circumstances, especially for undesirable actions. This cognitive bias is a key aspect of attribution theory, which seeks to understand how people interpret the causes of behavior.12
