TRAIT INFERENCES - SOURCES OF VALIDITY AT ZERO ACQUAINTANCE

Consensus between self-ratings and stranger ratings of personality traits was investigated. A sample of 100 adults was videotaped while entering and walking through a room, sitting down, looking into the camera, and reading a standard text. The targets then provided self-descriptions on 5 personality factors. A sample of 24 strangers who had never seen the targets before was given 1 of 4 types of information on the targets: (a) sound-film, (b) silent film, (c) still, or (d) audiotape. Strangers rated various physical attributes and 20 traits of each target. Level of information influenced the validity but not the reliability of the stranger ratings, which were most valid for extraversion and conscientiousness. Extraversion covaried most strongly with physical attributes, and implicit theories on the covariation of traits with physical attributes were more accurate for extraversion and conscientiousness than for agreeableness, emotional stability, and culture.
