CSI Effect

The CSI effect, also known as the CSI syndrome and the CSI infection, is any of several ways in which the exaggerated portrayal of forensic science on crime television shows such as CSI: Crime Scene Investigation influences public perception. The term most often refers to the belief that jurors have come to demand more forensic evidence in criminal trials, thereby raising the effective standard of proof for prosecutors. While this belief is widely held among American legal professionals, some studies have suggested that crime shows are unlikely to cause such an effect, although frequent CSI viewers may place a lower value on circumstantial evidence. As technology improves and becomes more prevalent throughout society, people may also develop higher expectations for the capabilities of forensic technology.

There are several other manifestations of the CSI effect. Greater public awareness of forensic science has also increased the demand for forensic evidence in police investigations, inflating workloads for crime laboratories. The number and popularity of forensic science programs at the university level have greatly increased worldwide, though some new programs have been criticized for inadequately preparing their students for real forensic work. It is possible that forensic science shows teach criminals how to conceal evidence of their crimes, thereby making it more difficult for investigators to solve cases.
