Participants were divided into three groups based on what they were told about the defendantfs criminal past: criminal record group (defendant had a criminal past), clean record (no criminal past), or no information group (no information regarding criminal past). Participantfs then rated the defendant from 1 (completely innocent) to 10 (completely guilty). The data are presented below.
