Social backgrounds,social motives and participation on the U.S. Supreme Court

This study explores the utility of psychological content analysis in studying judicial behavior. Justices' testimony before the Senate Judiciary Committee was scored for power, achievement, and affiliation imagery using content analysis techniques developed by Winter (1982a). The results suggest that motivational content analysis may provide a more direct means of assessing the relationship between judges' psychological disposition and their decision making behavior. Combinations of motive imagery variables and social background variables explained between 64% and 83% of the variation in writing opinions and in casting concurring and dissenting votes among U.S. Supreme Court justices.
