The positive predictive value of the polygraph (ie, the proportion of positive test results that are true positives) was assessed, on the evidence of the best published data for the sensitivity and specificity of the device. In many screening or investigative situations, the predictive value would be poor; most of the positive results would be false positives.

Researchers conducted mail surveys to obtain the opinions of 2 groups of scientists...
Survey return rates were high (91% and 74%, respectively). Most of the respondents believed that polygraphic lie detection is not theoretically sound, claims of high validity for these procedures cannot be sustained, the lie test can be beaten by easily learned countermeasures, and polygraph test results should not be admitted into evidence in courts of law

Reviews the literature on field and analog polygraph testing to aid Congressional consideration of efforts by the U.S. Department of Defense to expand use of polygraph tests to large numbers of government employees with access to classified information. It is noted that the validity of polygraph testing has yet to be established. The validity of control question analog studies is considered in relation to polygraph validity, and the effects of S. characteristics, setting, and countermeasures on validity are discussed.

(p. 214). In short, even if one is willing to overlook all of the glaring flaws with polygraphs and the ultimate impossibility of accurately measuring their accuracy, the best that can be said about them is that they detect deception better than random chance. Though it likely need not be said, "better than flipping a coin" seems a paltry justification for the still-widespread use of polygraphs in the criminal justice
Employee Privacy Torts Issues relating to employee privacy have been at the forefront of businesses for many years. This has been fuelled by the dynamic workplace which changes constantly and also by employees and employers being more litigation-conscious. Technology has also spurred on employee privacy issues with e-mail and the internet being related to heightened concerns about vulnerability of employers to litigation. Many employers have thus exacerbated their concerns relating to
In order to address the issues, efforts would be made towards the creation of stress free interviews and the preservation of objectivity. c) the psychological interview The psychological interview is characterized by assessment of the mental state of the individual. It is usually constructed based on standards of psychological testing and the results are interpreted by a specialist. d) the interview with the top management Finally, the interview with the top management would
