Can a person beat the polygraph?
Honest people will not try to beat the polygraph. The polygraph records the sympathetic system (the fight or flight syndrome). Counter measures are easily detected and usually only employed by dishonest individuals. Some individuals may take medication in attempts to relax them; however, it just relaxes them on all questions and they still react to the relevant issue. Counter measure devices such as the piezo-sensors are utilized to detect any bodily movement. It is virtually impossible to change the results of an examination.
