Syllabus: How Should We Understand Personality?
Return to the lexical approach and the decisions that produce a factor structure. Compare the resulting description with the broader framework, keeping labels separate from mechanisms.
Why you’re reading it. Give the trait approach a concrete empirical basis before asking it to explain a whole person.
A question to consider. If Sam and another person receive similar Big Five scores, which questions from McAdams and Pals would remain unanswered?
Why this reading
Goldberg investigates whether a small number of broad dimensions can organize a much larger vocabulary of personality descriptions. The studies make factor structure an empirical question about the terms selected, the people doing the rating, and the analysis used, rather than simply introducing a list of five trait names.
Before you read
The lexical hypothesis proposes that socially important differences become represented in everyday language. A loading indicates how a variable relates to a factor. Rotation changes the representation of extracted dimensions to aid interpretation; orthogonal rotation keeps them uncorrelated. These are continuous dimensions, not five types of people. The paper’s Intellect factor comes from descriptions and should not be equated with a performance-based intelligence score.
Read for
- Trace the selection and grouping of adjectives before interpreting the factor solutions.
- Distinguish robustness across analysis procedures from generalization across samples, raters, languages, and kinds of measure.
- Examine what the recurring five-factor structure describes and what evidence would be required to turn that description into an explanation.
Consider afterwards
- If a broad factor appears in self-descriptions and descriptions of peers, what has generalized—and what remains unknown about agreement on the same individual or about other cultures?
Editorial context
The studies support a descriptive structure within the English trait materials and largely student samples examined. They do not establish that five factors exhaust personality or settle the structure in every language. Later HEXACO work develops a six-dimensional alternative. Laajaj and colleagues also show why familiar questionnaire labels do not guarantee equivalent measurement in different settings. Distinguish a useful taxonomy from a complete theory of a person.
