Personality profiles describe individual persons' locations on multiple trait dimensions and enable calculation of profile similarity indices for individual persons and dyads. They are easily misinterpreted, however, unless two components are distinguished: a normative component comprising the sample means of the variables and a distinctive component reflecting the given individual's deviations from those means. These two profile components provide different kinds of information. Focusing on person-perception research, we review predictors of the similarity of individual profiles to the normative profile (i.e., profile normativeness) and of the agreement between distinctive profiles. We also provide some suggestions for future research.
