Trait structure
Use dimensions such as broad trait factors to summarize covariation without assuming categories are natural kinds.

Purpose
Stable and changing individual differences studied through traits, motives, self-concepts, situations and longitudinal patterns of behavior.
Structure
05 movesSystem mapV0
Components → constraints → flows → control → failure
Model persons as distributions across situations.
Personality psychology becomes stronger when traits are treated as probabilistic tendencies with developmental and contextual structure rather than fixed essences.
Measurement
Compare self-report, informant report and behavioral data while accounting for response style and context.
Person-situation interaction
Study how stable tendencies combine with situational cues to generate variable behavior.
Development & change
Track mean-level and rank-order stability across life transitions and intentional or environmental change.
Prediction & outcomes
Evaluate what personality measures add to prediction of relationships, work, health and behavior beyond demographic or situational factors.
Keep the boundaries visible.
trait ≠ destiny
type ≠ dimension
test reliability ≠ construct validity
Questions that organize the Side.
How stable must a pattern be to count as personality?
When does a trait explain behavior versus merely summarize it?
What evidence shows personality change rather than measurement drift?
What should carry weight here?
Use validated measures, longitudinal data and incremental prediction; avoid inferring deep mechanisms from descriptive trait labels alone.
