This study examines the phenomenon of suggestibility, where readers incorporate errors from fictional stories into their responses to general knowledge questions, even when these errors contradict well-known facts. The researchers aimed to determine if suggestibility is related to participants’ ability to assess the correctness of story content by highlighting certain phrases that required evaluation. Surprisingly, while highlighting aimed to improve monitoring, it led to an ironic effect where participants were more likely to recall story errors, indicating that failure to monitor for errors, rather than the ability to identify them, drives suggestibility
