We asked 101 participants from the UTEP campus to examine the lineup and try to pick the suspect. The expected ID rate per lineup member is 16.8. Here are the results:
12 | 1 | 2 |
77 | 6 | 3 |
Bias: .76 / .168 Size: 1.67 The bias figure means that 76% picked the suspect, in relation to 16.83% expected by chance (1/6). If the suspect does not stand out then people who know only the verbal description should not be able to pick him out at better than chance rates. |
