For example, consider factors like jury decision making, the role of groupthink in crimes where multiple perpetrators were involved, the social psychological motivations of folks who had information about the crime but didnt report it, issues of gender, confirmation bias, racism, family dynamics, the role of memory and its limitations, etc. In other words, if you dive into the true crime genre, youll find all sorts of psychological concepts to explore that are perfect for this assignment; lets just not over-focus on the sociopathic tendencies inherent in the perpetrators themselves.
