Final answer:
The Employee Polygraph Protection Act indeed restricts employers from using polygraph tests for most employment-related circumstances, a fact that correlates with the dubious effectiveness of such tests in accurately detecting dishonesty.
Step-by-step explanation:
The statement regarding the Employee Polygraph Protection Act is true. With a few exceptions, this Act generally prohibits employers from using polygraph tests for pre-employment screening or during the course of employment. The Act aims to prevent potential abuse of polygraph testing and to protect employees' rights. The polygraph measures physiological arousal, but its effectiveness is dubious as strong emotional responses can occur for reasons other than dishonesty. This inaccuracy forms one of the bases for the restrictions imposed by the law.
