Lack of understanding, overconfidence lead to investigative errors, researcher says

Why do police make the same false assumptions and continue to use outdated investigative techniques even after the mounting number of exonerations proves them wrong?

British researchers Julia Shaw and Chloe Chaplin conducted a survey to find out. They discovered that police officers are just as ill-informed on important policing issues as everyone else but “exhibited higher confidence in their judgements than the general public, making them more confidently wrong.” You can read Shaw’s examination of this problem here.
