Consensus Intelligence Testing in Compatible and Incompatible Groups

Abstract

Summary The study concerned consensus intelligence testing which involves two test administrations, the first to each member of a group separately and the second to all group members simultaneously. The groups, each consisting of adolescent pairs, were instructed to arrive at a best single answer. It was hypothesized that compatible roommates would obtain a higher consensus IQ (WAIS, abbreviated scale) than incompatible roommate pairs, even when individual IQs were equivalent. Compatibility was operationally defined by rankings made by the adolescents who served as judges as well as Ss. The data supported the hypothesis.
