Most of the participants in the study either misidentified the suspect or stated the suspect was not in the line-up at all. Correct identification of the suspect occurred more often when the eyewitness and the suspect were of the same race.[26] In another study, 86 convenience store clerks were asked to identify three customers: one white, one black, and one Mexican, all of whom had purchased in the store earlier that day. The clerks tended to identify customers belonging to their own race accurately, but were more likely to make errors when attempting to identify other races members.[27] Meanwhile, another study found that "alcohol intoxication reduces the own-race bias in face recognition," albeit by impairing accurate perception and leaving in place or increasing random error rather than by improving facial recognition of members of other groups.[28]
