Gísli Hannes Guðjónsson, CBE (born 26 October 1947) is an Icelandic Professor of Forensic Psychology at the Institute of Psychiatry of King's College London. He is an internationally renowned authority on suggestibility and false confessions whose expert testimony was the basis for the convictions of the Birmingham Six and Guildford Four being overturned. He created the Gudjonsson suggestibility scale to measure how susceptible someone is to coercion during an interrogation.
In 1982, he coined the term memory distrust syndrome, to describe those who distrust their own memories and are motivated to rely on external (non-self) sources to verify the accuracy of memories.
