Feedback suggestive of mistaken eyewitnesses claiming that they identified the correct person leads to distorted retrospective judgments of certainty, view, and other testimony-relevant measures. This feedback effect can be significantly mitigated if witnesses later learn that the feedback source did not know which lineup member was the correct person and had a manipulative intent (postfeedback suspicion manipulation). We replicated the postfeedback suspicion effect and used a mistake condition showing that the manipulative intent is not a necessary component, thereby ruling out reactance-type interpretations of the post-feedback suspicion effect. Some conditions included instructions to ensure relevant processing of the feedback before the post-feedback suspicion manipulations, but these processing instructions did not mitigate the effect. The results suggest that these retrospective judgments (e.g., certainty, attention, view) remain malleable as new information unfolds.
