What are the limitations and barriers of polygraph technique?
One limitation of the GKT is that it can be used only when investigators have information that only a guilty subject would know. The interpretation of “no deception” is also a potential limitation, since it may indicate lack of knowledge rather than innocence.
What is the barriers of polygraph examination?
Field studies of polygraph testing are plagued by selection and measurement biases, such as the inclusion of tests carried out by examiners with knowledge of the evidence and of cases whose outcomes are affected by the examination. In addition, they frequently lack a clear and independent determination of truth.
What are the 2 factors that affects the reliability of polygraph examination?
In addition to subjects’ psychopathy, other diagnostic categories and subject variables such as gender, intelligence, motivation, and responsivity to arousal may also affect validity. Subject factors are often described in the literature as personality or individual difference factors (136,194).
What are the factors that affect the accuracy of the polygraph results?
Variables, or factors that can affect the accuracy of polygraph tests include personality disorders, drug use, mental health, the environment the test is given in, the examiner giving the test, and gender and ethnicity.
Are polygraph tests 100\% reliable?

What factors influence the validity of CQT polygraphs?
Research on the processes involved in CQT polygraph examinations suggests that several examiner, examinee, and situational factors influence test validity, as may the technique used to score polygraph charts.
