Document Summary
Chapter 5 deception detection in the legal system: Traditionally, courts of law assumed judges/juries able to determine whether someone telling truth on stand: but injustice cuz of inability of legal decision makers to recognize lying. Dissociative amnesia- little/no memory for event: when traumatized by event, even perpetrators of extreme violence get da, cant be attributed to head injury/intoxication. Triers of fact decision making subject to biases. Judges form impressions of credibility from witnesses demeanour that influences decisions, but little evidence for validity of this process: suggestions that both judges/cops poorly equipped to identify deceit. Widespread reliance in stereotypical cues to lying that aren"t valid. When relied on a single dominant cute to lying/gut instinct, tended to make mistakes. Ppl tend to associate nervousness [speech errors, gaze aversion] body movements/shifting with lying: research shows liars often beh in completely diff manner. Use grew rapidly in 1970s cuz rules in most regions permitted wide admissibility of hypnotically induced memories.
