An apparent exception to the extremization of collective judgments


  • Paper presented to the European Association of Experimental Social Psychology working group on Social Judgment, Konstanz, September, 1970. The author is indebted to Dr. Kogan and Dr. Wallach for providing him with their data. He also thanks Mlle Chatenet for her collaboration and Mlle Sinclair for translating the original French manuscript.


A reanalysis of data obtained by Kogan and Wallach, 1966 is presented. Wherever the original analysis showed the extremity of unanimous group judgments in general not to be different from the average extremity of individual judgments, the present analysis indicates that these group judgments differ from the average of individual judgments: they are significantly more extreme than the average positions of the individuals.
