"Measures of discrepancy between an objective group preference hierarchy structure of members and an individual estimate of this preference hierarchy structure were obtained for members of infantry rifle squads who had scored high and low on a criterion field problem." It was found that the appointed leaders, popular individuals, and members of effective groups were better able to estimate the preference hierarchy structure than were non-leaders, less popular individuals, and members of ineffective groups.
