Interesting that the entire article had nothing to mention about the Reid technique [1]. The Reid technique has been used by law enforcement to convince criminals of confessions. Many confessions were found to be false. In the book by Carol Tavris and Elliot Aronson [2], they cover false confessions in depth with a few court cases, as well as police techniques to invoke cognitive dissonance in the accused. Callout to the book though, for self-deception and cognitive dissonance is something that affects us all!
