What phenomenon can cause a witness to misremember details due to suggestion or pressure?

The phenomenon that causes a witness to misremember details due to suggestion or pressure is linked to post-event misinformation. This occurs when information provided after an event influences a person's memory of that event. For instance, if a witness is exposed to misleading information—such as leading questions or discussions with others—they may incorporate that misinformation into their recall, leading to inaccuracies. This is particularly relevant in investigative contexts, where the framing of questions or presentation of additional information can shape a witness's memories and ultimately affect the reliability of their testimony.

While memory reconstruction refers to the process of remembering an event, and memory bias pertains to the ways in which our personal beliefs and knowledge can alter our recollections, these concepts do not specifically address the impact of external suggestions on memory recall. False memory syndrome describes instances where individuals recall events that didn't occur or have been distorted significantly, but post-event misinformation focuses more directly on how subsequent information affects original memories, making it the most relevant choice in this context.
