Summary and Keywords
Prosecutors and members of law enforcement have complained that television shows such as CSI: Crime Scene Investigation have cultivated in jurors’ unreasonable expectations about forensic evidence, specifically that jurors require definitive forensic proof of guilt, or else they will wrongly acquit. This is popularly known as “CSI Effect.” Despite the popularity of this belief, there is little empirical evidence substantiating it. In fact, the majority of studies exploring CSI Effects have found evidence supporting a variety of impacts that advantage, rather than disadvantage, the prosecution. For instance, these programs frame forensics as objective and virtually infallible, bolster forensic technicians and the value of evidence associated with them, and promote schema that endorse prosecution narratives. Indeed, it appears that among CSI’s most salient impacts on the legal system comes not from these television programs distorting juror decision-making, but because lawyers and judges mistakenly believe such an effect exists, and, therefore, alter their behavior in response. It thus appears that the realities of the CSI Effect are quite different than the persistent mythology of it.
