# Big Five Framework

**Profile:** A well-established, multi-dimensional psychometric model (also called the Five-Factor Model / OCEAN) measuring five personality dimensions: **openness, conscientiousness, extraversion, agreeableness, and neuroticism**. Canonical reference: standard psychology references on the Big Five.

**Role in source:** Suggested as a **training-data source** to help AI agents develop nuanced, non-binary personality traits rather than the extreme, binary profiles produced by persona prompting (see [[action-enrich-training-data]] and [[concept-cosmetic-ai-diversity]]). It is one of the two named datasets in the second imperative of the [[framework-seven-imperatives]].

**Enrichment note:** Big Five inventories are canonical in psychology; however, directly encoding psychometrics into models raises non-trivial ethics and privacy questions and is not yet standard foundation-model practice.
