The relationships of heterogeneity on personal history and personality variables to group compatibility and accomplishment were studied in 15 groups of scientists and Navy men who manned scientific stations in Antarctica. Group effectiveness criteria were mean scores on questionnaire items which described the group as a whole and which were administered to group members after several months of isolation and confinement. Heterogeneity group standard deviations on urban-rural residence, importance of hobbies and recreational interests, and personality needs most relevant to group integrity and achievement were significantly related to group performance. These exploratory findings should help develop useful approaches to the group assembly program.
