This study identifies individuals who are habitually susceptible to accepting postevent misinformation across testing on three separate events. The results indicate that those individuals identified as habitually susceptible exhibited higher dissociation scores and less of an association between memory accuracy and confidence than did the individuals identified as nonhabitually susceptible. When they were asked to identify the source of the remembered information, similar patterns of source attributions were found for all individuals when they were responding correctly and incorrectly to nonmisinformation and when they were correctly rejecting items of misinformation. Importantly, from a source-monitoring perspective, individuals identified as habitually susceptible demonstrated a different pattern of source attributions than did those classified as nonhabitually susceptible when they were accepting misinformation. Habitually susceptible individuals were as likely to attribute the source of their memory incorrectly to something seen in the experienced event as to attribute it correctly to something read after the fact.
