Do you often find yourself watching those prime-time crime dramas on TV asking yourself, "Wow! I didn't know they could figure out whom the killer is based on a single carpet fiber sample found on the sidewalk outside of a crime scene! Can they really do that?!?" Well, some of the processes we see on TV may not be quick as quick and easy, or even possible compared to real life crime investigation.
Lisa Smith, of the University of Leicester School of Psychology, is doing some research to see how these portrayals of forensics on TV are affecting how jurors view forensic evidence in actual court cases. Jurors make their decisions based upon their knowledge, perceived understanding, and beliefs regarding forensic evidence. So the next time you are watching some evening television or even hear a news story regarding some forensic evidence, think twice about the validity of what you see!
