Similarity of trait construal and consensus in interpersonal perception

This study examined the roles of similarity of trait construal and length of acquaintanceship in interpersonal consensus. Pairs of roommates were asked to rate a mutual acquaintance on six ambiguous traits and to describe their behavioral definitions of those traits. They were then asked to rate the acquaintance again, once on the basis of their own definition of the trait and then on the basis of their roommate’s definition of the trait. Consensus was greater when roommates based their judgments on the same, shared trait definitions than when they based their judgments on their own unshared trait definitions. Furthermore, those roommates who reported similar trait construals exhibited significantly higher consensus in their initial unrestricted judgments of the mutual acquaintance than did those whose trait construals were dissimilar. Length of acquaintance appeared unrelated to similarity of trait construal and consensus. Discussion focuses on trait construal, interpersonal agreement, and social judgment.
