Because these 'changers' (member of the jury) are the key to the group decisionmaking process, they were carefully scrutinized to ascertain demographic or personality characteristics which might be mediating their behavior. In three experiments, two using college students and one using Philadelphia Court of Common Pleas jury pool members, it was found that authoritarians changed their attitude regarding the defendant's guilt more than equalitarians. Further, most of these 'changers' were aware they had changed their attitude. There was no generalizable evidence for the proposition that authoritarians are more likely to favor a guilty verdict.
