Does watching the work of fictional forensic investigators on TV influence viewers? There is a belief that this is the case and that the consequences of people watching shows such as the American crime drama television series CSI: Crime Scene Investigation are filtering through into real life, a phenomenon that has been called the CSI effect. In the worst case, it is feared, studious criminals will learn how to better conceal crimes. In addition, concerns have been expressed that members of U.S. juries may now have excessive expectations regarding the evidence and as a result are more likely to acquit the accused. A team of psychologists at Johannes Gutenberg University Mainz working under Professor Heiko Hecht have now sounded the all-clear—at least in one respect. In an experimental study, the German researchers have been able to find no evidence of a correlation between watching forensic science TV shows and the ability to get away with committing a crime. This is the first study to look at the question of whether criminals could profit from viewing dramas of this sort.
