framework · psychology · structured-empirical

Five dimensions of personality: Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism.

The Five-Factor Model of personality identifies five broad dimensions (Openness, Conscientiousness, Extraversion, Agreeableness, Neuroticism) that have replicated across decades of factor-analytic research and across cultures. The model emerged from lexical analysis of personality descriptors in natural language and was consolidated through the work of Costa and McCrae and others in the 1980s and 1990s. It is the dominant taxonomy in academic personality psychology and shows modest predictive validity for life outcomes including job performance, relationship stability, and longevity.

Five factors may collapse meaningful variation captured by more granular models like HEXACO
descriptive rather than explanatory (doesn't tell you why traits cluster)
Western cultural origin may limit cross-cultural applicability despite replication studies.
