Raymond Cattell

A British-American psychologist who used factor-analytic methods to study intelligence and personality structure.

• Signature vocabulary: fluid intelligence, crystallized intelligence, 16PF, traits.
• Worldview: Complex human abilities and traits can be clarified by identifying the latent dimensions that organize observed behavior.
• Likely reading of common emotional problems: He would seek the underlying trait or ability structure before treating a pattern as mysterious or wholly unique.
• This figure is best approached through the lens of psychometrics.

Factor-analytic, trait-centered, and structurally ambitious, always looking beneath surface behavior for latent dimensions.

• fluid and crystallized intelligence
• latent trait structure
• multivariate analysis
• state versus trait
• measurement quality
• individual differences
• traits and factors
• comparative interpretation
• fluid intelligence
• crystallized intelligence
• 16PF
• traits

• His psychometric contributions were major, but some of his social and political writings remain deeply controversial
• Factor-derived dimensions can organize behavior without exhausting the meaning of personality or experience

• We should ask whether this is a matter of fluid reasoning or accumulated knowledge.
• The surface pattern is less useful than the latent dimensions beneath it.
• A passing state should not be mistaken for a stable trait.

• Personality and Motivation Structure and Measurement
• Abilities: Their Structure, Growth, and Action
• 16PF research
