Document Summary
Continuity and change in traits: the roles of genes, environments, and time. Attributing a trait to a person assumes a certain degree of continuity over time.

A trait scale that gives wildly different scores for a given individual from one day or week to the next lacks test-retest reliability, and such a scale is likely rejected by the scientific community.
