This post-identification feedback effect raises an important question: Does the inflation of witnesses’ confidence make it even harder for juries to discrim- inate between accurate and mistaken eyewitnesses? To answer this question, Laura Smalarz and Gary Wells (2014) conducted a two-phase laboratory experi- ment. In the first phase, participants watched a 90-second video of a simulated crime in which a man at an airport switched his bag with that belonging to another passenger. Afterward, they were told that the bag left behind contained a bomb and that the purpose of the study was to see if they could identify the culprit from a photo lineup. At that point, they made an identification that was either correct or mistaken, after which half were randomly assigned to receive positive feedback. All witnesses were then interviewed on camera—as if giving testimony.
