The CSI effect: Watching TV crime shows does not make better criminals

    Psychological study finds no link between exposure to popular forensic science dramas and the ability to conceal a crime / Publication in the International Journal of Law, Crime and Justice

    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, potential criminals will learn how to better conceal a crime from these shows. 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.

    CSI: Crime Scene Investigation is a popular U.S. TV series which first hit the small screen in its home country in 2000. It focuses on the characters and the work of a team of forensic crime scene investigators. The effect named for this series was soon applied to any repercussions that it was held such widely-viewed crime shows had with regard to the general public—including criminals, the police, and potential students of forensic medicine. "Over many years, it was presumed that certain links in this regard exist, although there were no appropriate studies to prove this," said Dr. Andreas Baranowski. He and his colleagues at Mainz University have now undertaken four separate investigations of related claims with the aim of obtaining the most reliable possible findings.

    As a first step, the psychologists took a look at statistics from the databases of the FBI and its German equivalent, the Bundeskriminalamt (BKA), and compared the crime detection rates during the years preceding the launch of the CSI series with the subsequent rates. Then they asked 24 convicted criminals in prisons for their opinions on series such as CSI and whether they thought such shows could help when it came to escaping prosecution. Thirdly, the researchers put together a complex experimental design to find out whether viewers of TV shows like CSI would, as trial subjects, actually be better equipped to erase the traces of an, in this case, mock crime. Baranowski and his colleagues completed their series of trials in the form of a fourth test, in which a crime was re-enacted with the help of a doll's house.

    No CSI learning effect for criminals

    On the whole, the researchers did not find any connection between watching forensic dramas and the ability to successfully avoid detection after committing a crime. However, the male subjects in the fourth part of the experiment performed better than female subjects, and younger subjects better than older subjects while more highly educated subjects did better than less well educated study subjects. Study subjects working in technical professions, primarily men, appear to have certain advantages when it comes to concealing crimes.

    Baranowski pointed out it had already been postulated in the past that something like the CSI effect could exist. Starting with Sherlock Holmes and continuing as police procedurals, such as Quincy and Law & Order, appeared on TV, warning voices made themselves heard that the wrong kind of people could benefit from the insights provided. "Every time something new emerges there are people who focus in one aspect and without a full and proper consideration sense possible risks and thus call for bans." The findings in this context can be said to pour cold water on attitudes like this. "We can now dispel certain of the myths that have been coursing through the media and other publications for the past 20 years because we are able to state with relative certainty that people who watch CSI are no better at covering their tracks than other people."

    Dr. Andreas Baranowski supervised the study, "The CSI-education effect: Do potential criminals benefit from forensic TV series?," at the Division of General Experimental Psychology at Johannes Gutenberg University Mainz and works as a postdoctoral researcher in psychology at Giessen University.
