A polygraph, often incorrectly referred to as a lie detector test, is a junk science device or procedure that measures and records several physiological indicators such as blood pressure, pulse, respiration, and skin conductivity while a person is asked and answers a series of questions. The belief underpinning the use of the polygraph is that deceptive answers will produce physiological responses that can be differentiated from those associated with non-deceptive answers; however, there are no specific physiological reactions associated with lying, making it difficult to identify factors that separate those who are lying from those who are telling the truth.
Leonarde Keeler was the co-inventor of the polygraph. He was named after the polymath Leonardo da Vinci, and preferred to be called Nard. He was a Berkeley high school student and amateur magician. He was captivated by John Augustus Larson's machine, a "cardio-pneumo psychogram", with the goal of detecting deception, and worked on it to produce the modern polygraph.

Lie detection is an assessment of a verbal statement with the goal to reveal a possible intentional deceit. Lie detection may refer to a cognitive process of detecting deception by evaluating message content as well as non-verbal cues. It also may refer to questioning techniques used along with technology that record physiological functions to ascertain truth and falsehood in response. The latter is commonly used by law enforcement in the United States, but rarely in other countries because it is based on pseudoscience.

The Silent Talker Lie Detector is an attempt to increase the accuracy of the most common lie detector, the polygraph, which does not directly measure whether the subject is truthful, but records physiological measures that are associated with emotional responses. The Silent Talker gives the evaluator access to viewing microexpressions by adding a camera to the process. The creators claim that microexpressions are actual indicators of lying, while many other things could cause an emotional response. Since microexpressions are fleeting, the camera allows the examiner to capture data that otherwise would have been missed. However, the scientific community is not convinced that this system accomplishes what it claims and some call it pseudoscience.
Othello error occurs when a suspicious observer discounts cues of truthfulness. Essentially the Othello error occurs, Paul Ekman states, "when the lie catcher fails to consider that a truthful person who is under stress may appear to be lying," their non-verbal signals expressing their worry at the possibility of being disbelieved. A lie-detector or polygraph may be deceived in the same way by misinterpreting nervous signals from a truthful person. The error is named after William Shakespeare's tragic play Othello; the dynamics between the two main characters, Othello and Desdemona, are a particularly well-known example of the error in practice.
