THE STUDY WAS CONDUCTED TO DETERMINE HOW KNOWLEDGE OF THE DEFENDANT'S RECORD SERVES TO INCREASE THE PROBABILITY OF HIS CONVICTION IN BOTH INDIVIDUAL AND GROUP VERDICTS. A HYPOTHETICAL CASE WAS PRESENTED TO PARTICIPANTS, WITH HALF RECEIVING ADDITIONAL INFORMATION ON THE DEFENDANT'S PRIOR CONVICTION ON A SIMILAR CHARGE. IT WAS FOUND THAT JURIES WITH RECORD INFORMATION WERE MORE LIKELY TO CONVICT THAT INDIVIDUALS WITH RECORD INFORMATION WHILE BOTH OF THESE WERE MORE LIKELY TO CONVICT THAT GROUPS OR INDIVIDUALS WITH NO RECORD INFORMATION. THE AUTHORS CONCLUDE THAT KNOWLEDGE OF A PRIOR CONVICTION BIASES A CASE AGAINST THE DEFENDANT.
