Abstract:This research focuses on how lineup a administrators influence eyewitnesses' postidentification confidence. What happens to witness confidence when a witness makes an identification that confirms the lineup administrator's expectations; what happens when this expectation is not confirmed? In Experiment 1, participant interviewers (n = 52) administered target-absent photo lineups to participant witnesses (n = 52). The interviewers did not view the simulated crime, but were told the thief's position in the lineup. In every instance this information was false (we used a target-absent lineup). A one-way ANOVA revealed that eyewitness identification confidence was malleable as a function of interviewers' beliefs about the thief's identity. In Experiment 2, participant jurors (n = 80) viewed 40 testimonies of Experiment 1 witnesses (2 participants viewed each testimony). Participant jurors judged all participant witnesses as equally credible despite their varying levels of postidentification confidence.
