Coming to suspect that someone has engaged in wrongdoing based on their unexpected behavior is a common phenomenon—yet, little is known about what triggers initial suspicion. We investigated how violating expectations for high emotionality during a traumatic event can trigger suspicion that one has engaged in immoral—or even criminal—activity through moral typecasting. Five studies demonstrate this theory in a criminal context with dire real-world consequences: 911 callers reporting violent crimes generating suspicion by exhibiting unexpected behavior, which could trigger confirmation bias in investigations leading to wrongful convictions. Using both real and tightly controlled simulated 911 calls, we demonstrated that failing to express the expected level of emotion on a 911 call reporting a violent crime led laypeople and police to morally typecast the caller as more of a moral agent capable of perpetrating immoral acts and less of a moral patient capable of being the victim of immoral acts—ultimately increasing suspicion that they were involved in the crime and support for treating them as a suspect. We advance moral psychological theory by demonstrating that failing to express expected levels of emotion about a moral violation can shape moral inferences about someone’s capacity to commit versus be the victim of moral wrongs, thereby generating suspicion that they might have engaged in wrongdoing. We demonstrated this theory in criminal settings to explain how one tragedy can become two: altruistic witnesses calling 911 to plead for help on behalf of another person becoming suspects of the crime they reported because they failed to exhibit the expected emotional demeanor.

Exposure to even subtle forms of misleading information can significantly alter memory for past events. Memory distortion due to misinformation has been linked to faulty reconstructive processes during memory retrieval and the reactivation of brain regions involved in the initial encoding of misleading details (cortical reinstatement). The current study investigated whether warning participants about the threat of misinformation can modulate cortical reinstatement during memory retrieval and reduce misinformation errors. Participants watched a silent video depicting a crime (original event) and were given an initial test of memory for the crime details. Then, participants listened to an auditory narrative describing the crime in which some original details were altered (misinformation). Importantly, participants who received a warning about the reliability of the auditory narrative either before or after exposure to misinformation demonstrated less susceptibility to misinformation on a final test of memory compared to unwarned participants. Warned and unwarned participants also demonstrated striking differences in neural activity during the final memory test. Compared to participants who did not receive a warning, participants who received a warning (regardless of its timing) demonstrated increased activity in visual regions associated with the original source of information as well as decreased activity in auditory regions associated with the misleading source of information. Stronger visual reactivation was associated with reduced susceptibility to misinformation, whereas stronger auditory reactivation was associated with increased susceptibility to misinformation. Together, these results suggest that a simple warning can modulate reconstructive processes during memory retrieval and reduce memory errors due to misinformation.
