Watching TV crime shows does not make better criminals

Watching popular crime TV shows or forensic science dramas does not help criminals learn how to better conceal their wrongdoings, a study has found.

There is a belief that watching the work of fictional forensic investigators on TV influence viewers.

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 juries may have excessive expectations regarding the evidence and as a result are more likely to acquit the accused.

In an experimental study, researchers at the Johannes Gutenberg University Mainz in Germany found no 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, researchers said.

"CSI: Crime Scene Investigation" is a popular US 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 Andreas Baranowski from Mainz University.

The study, published in the International Journal of Law, Crime and Justice, undertook 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.

Researchers 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.

On the whole, they 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.

"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," Baranowski said.
