The graphic results of the interrogation were printed large across the page, with arrows marking each presumed lie. [36], Several proposed countermeasures designed to pass polygraph tests have been described. The review also warns against generalization from these findings to justify the use of polygraphs"polygraph accuracy for screening purposes is almost certainly lower than what can be achieved by specific-incident polygraph tests in the field"and notes some examinees may be able to take countermeasures to produce deceptive results.[23]. A polygraph, often incorrectly referred to as a lie detector test,[1][2][3] is a 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. [80] According to a Senate investigation, an FBI review of the first examination concluded that the indications of deception were never resolved. Langleben has reported being able to correctly classify individual lies or truths 78 percent of the time. Sociopaths can pass because they don't feel guilt.

The accuracy of human judges, by comparison, is at best 54 to 60 percent, according to AVATARs developers. [12] By adding a camera, the Silent Talker Lie Detector attempted to give more data to the evaluator by providing information about microexpressions. The new machine used an ink polygraph system, and had mechanical metal bellows, a motor drive, a pneumograph to go around the chest, and a mechanical indicator that would mark data on graph paper.

Detractors see many alternative explanations for positive results and cite a preponderance of evidence that polygraph tests are no more reliable than guesswork. (In 2010, IEEE Spectrum contributing editor Mark Harris wrote about his own close encounter with an fMRI lie detector. She also appears in a picture taken in his polygraph laboratory in the 1920s (reproduced in Marston, 1938). It does not store any personal data.

[50] As of 2013, about 70,000 job applicants are polygraphed by the federal government on an annual basis. However, Larson himself used to refer to his apparatus as a 'cardio-pneumo psychogram,' which basically consisted of a modification of an Erlanger Sphygmomanometer.[8]. However adding the Silent Talker camera did not improve lie detection and was very expensive and cumbersome to include according to an article in the Intercept. Its reliability is often debated, but the polygraph measures a subjects physiological activity like blood pressure, pulse, respiration, and skin conductivity to try to determine if they are answering questions honestly. SiliconExpert provides engineers with the data and insight they need to remove risk from the supply chain. Although the relevant questions in the probable lie test are used to obtain a reaction from people who are lying, the physiological reactions that distinguish lies may also occur in innocent individuals who fear false detection or feel passionately that they did not commit a crime. He invented a systolic blood pressure cuff and with his wife, Elizabeth Holloway Marston, used the device to investigate the links between vital signs and emotions.
