Lie Detector Assumption

Problem Statement

Lie Detector Assumption: A lie detector, or polygraph, monitors several physical reactions in the person undergoing the test. Befooling a lie detector test is quite easy. A small dose of a widely used over the counter stress-busting drug can allow a person to lie during lie detection tests without being caught. The stress created by the response to a question that lie detectors measure can be stabilized by the drug without being noticed. The drug is already an effective medicine in reducing stress in day to day situations. Which of the following is an assumption in the argument above? The drug is not detectable by standard blood tests administered before a polygraph. The effectiveness of the stress-busting drug is not compromised by other physiological indicators that the lie detector may measure. Most people who take lie detector tests are already using stress-busting drugs for medical reasons. Lie detectors are only capable of measuring stress-related physiological responses. Arrange
