Document Summary
People aren t good at detecting deception tend to rely on unreliable cues tend to have a truth bias. Experts (police, fbi, judges, etc) are no better than laypeople may tend to underperform because those in the law enforcement are overly skeptical there is a potential to train people so they can detect deception better. Nonverbal cues liars use a higher voice pitch (best predictor) more tense/less shifty increased self-touching/fidgeting increased eye blinks and pupil dilation smiling/laughing inappropriately is not a cue. *keep in mind that no single cue is reliable. *premise of this is the same as polygraph testing, where arousal is used to predict lying. Recall memory retrieving information from the past about events/people more difficult that recognition memory ex. short answer questions should be more difficult than multiple choice questions. Fisher and colleagues (1987, 1995, 2011) research pinpointed a general procedure for police interviews.
