Forensic "Lie Detection"

Why after reading this article below, by a Doctor no less, is polygraph a requirement for an SO. It is hard enough to gather money just to live along with all the other money needed for therapy classes, parole/probation fines and not to mention not being able to get a job because of the SO status and much more that others don't think about?

 

 

Forensic "Lie Detection":
Procedures Without Scientific Basis

William G. Iacono, PhD

Although the CQT may be useful as an investigative aid and tool to induce confessions, it does not pass muster as a scientifically credible test. CQT theory is based on naive, implausible assumptions indicating (a) that it is biased against innocent individuals and (b) that it can be beaten simply by artificially augmenting responses to control questions. Although it is not possible to adequately assess the error rate of the CQT, both of these conclusions are supported by published research findings in the best social science journals (Honts et al., 1994; Horvath, 1977; Kleinmuntz & Szucko, 1984; Patrick & Iacono, 1991). Although defense attorneys often attempt to have the results of friendly CQTs admitted as evidence in court, there is no evidence supporting their validity and ample reason to doubt it. Members of scientific organizations who have the requisite background to evaluate the CQT are overwhelmingly skeptical of the claims made by polygraph proponents.
