A method taught to police interrogators since the 1970s is called the Reid technique. It was named for a Chicago police officer who developed it in the 1940s. It is widely used in North America because it gets confessions; sometimes false confessions. It is based on outdated psychology that maintains if a person shows stress they are lying. Unfortunately most people show stress when in stressful conditions. Suspects are questioned, often by teams of police officers. The Good cop/bad cop routine seen on police procedural shows is an example of the Reid technique. The police use this method to convince a suspect that confessing to the crime (whether they are guilty or not) is the best way out for the suspect. Many false confessions have been obtained this way resulting in false inprisonments.
