What is it about?

This study showed that people high in paranoid thinking were more likely to falsely recognize a new item as having been previously presented. We identified two processes that contributed to this effect: (a) an overreliance on nonspecific feelings of familiarity when making memory judgments and (b) overconfidence in those judgments, potentially related to a reduced ability to question one’s own mistakes.
