Twenty-three five man groups of MBA students, who had received a nine instrument personality test battery, discussed four human relations cases. An observer counted the number of times each student talked. Students ranked each other on Best Ideas, Guidance, Leader, and Being Liked. Forty-two personality scales plus undergraduate grade point average were compared to the highest and lowest men on each of the four sociometric choices and on times talking. Twenty personality scales had 28 differences significant at the .05 level or higher between the highest and lowest men in the groups. Individual Background Survey was higher for each of the four choices and for frequency of talking. There were significant differences in six of the Guilford-Zimmerman Temperament Survey scales, five of the MMPI scales, two of the Ghiselli Self-Description Inventory scales, two of the SVIB scales. There were also significant differences on Consideration of the Leadership Opinion Questionnaire, Public Opinion Questionnaire California F-scale, and Need for Achievement. Generally the personality of the highest chosen men was ascendant, active, and dominant. Men chosen as Leader in the fourth session also talked more frequently and often chosen for Participation, Best Ideas, and Guidance in both session four and session one. Being Liked was much less closely associated with choice as Leader. Author
