Legal Definitions - CSI effect

The CSI effect is a phenomenon where television shows like CSI: Crime Scene Investigation, Law & Order, and 48 Hours Mystery can influence jurors' perceptions of forensic evidence in a criminal case. Jurors who watch these shows may place a high value on forensic science and believe that it is always accurate and should be present in every criminal case.

For example, a juror who watches CSI may expect to see DNA evidence presented in a case, and if it is not, they may be less likely to vote to convict. This can create unrealistic expectations for jurors and make it more difficult for prosecutors to secure convictions.

The CSI effect can also lead to misconceptions about the capabilities of forensic science. For instance, jurors may believe that forensic evidence can always identify a suspect with certainty, when in reality, it is often more complex and nuanced than that.

Overall, the CSI effect highlights the influence that media can have on our perceptions of the criminal justice system and the importance of educating jurors about the limitations and complexities of forensic evidence.
