Episode 41: Criminal justice and forensic science

Episode 41: Criminal justice and forensic science

Author: Tom Chivers and Stuart Ritchie June 18, 2024 Duration: 1:01:35

The criminal justice system and science are both broadly looking for the same thing - the truth. But in many cases the two don’t mix well. Whether it’s court cases that attempt to decide the truth of a scientific dispute, or the use of fingerprints, DNA, or statistics by the prosecution in a murder case, a lot can go wrong - and there’s a lot at stake.

Inspired by the recent discussion, or perhaps lack of discussion, around [a criminal case nobody in the UK can talk about for legal reasons], Tom and Stuart spend this episode looking into what happens when science meets the law.

Our favourite online magazine is Works in Progress - so it’s particularly pleasing that they’re the sponsors of The Studies Show.
