Polygraph Testing Dont’s & Do’s

On Junk-Science in the Medical Profession

A SPECIAL ME-P REPORT

By Michael Lawrence Langan MD

***

If you are ever asked to take a polygraph test–don’t do it. Those involved in the criminal justice system, including lawyers, are largely uneducated in the realm of scientific scrutiny and experimental methodology.

They may not separate science and pseudo-science, and erroneously believe that the polygraph is an accurate scientific instrument. Their interactions are with polygraph examiners who proselytize its use, and they have little or no interaction with scientists, psychologists, and physicians who refute its use.

Refuse to take the test and educate them. Cite the Frye Doctrine, go to the medical library, copy the scientific articles which belie its validity, and present them to whomever requested you to take the test. State that the principles and assumptions underlying polygraphy are not supported by our understanding of psychology, neurology, and physiology.

Assessment

Then, put the burden of proof on their heads. Tell them to present you with scientific evidence that corroborates the validity of the test. There is simply no rational basis for a machine to detect liars.
