Persuasiveness and Persuasibility as Related to Intelligence and Extraversion*

Abstract

Each pair of subjects in this experiment was required to discuss a topic on which they initially disagreed. The persuasiveness of one over the other was defined as shorter latency of first statement, and larger amount of participation, and persuasibility as likelihood of opinion change. Predictions of outcome were made for three groups of subjects paired in the following manner: Group I, high intelligent‐extraverted vs high intelligent‐extraverted; Group 2, high intelligent‐extraverted vs high intelligent‐introverted; and Group 3, high intelligent‐extraverted vs low intelligent‐extraverted. Results indicated that more intelligent and extra‐verted subjects are more persuasive and less persuasible.
