Effect of Group Heterogeneity on Quality of Task Solutions
Michael G. Aamodt, Wilson W. Kimbrough · Psychological Reports · 1982
Subjects were placed into groups on the basis of either trait homogeneity or heterogeneity with the other group members and were given a group task to complete. The results indicated group answers of superior quality when the group was composed of heterogeneous individuals rather than homogeneous individuals.
