Final answer:
A deceptive person with control over their physiological responses has the best chance of cheating a lie detector test due to the test's reliance on detecting arousal that may not be consistently linked to lying.
Step-by-step explanation:
Considering the reliance of a polygraph test on detecting signs of physiological arousal that may indicate dishonesty, a deceptive person who understands how to control their physiological responses, or who doesn't experience the typical arousal associated with lying, would have the best chance of cheating a lie detector test. This is because polygraphs measure parameters such as heart rate, respiration rate, and sweating, looking for unusual fluctuations that might denote deceptive behavior. However, given that there's no definitive pattern of physiological arousal linked to lying, the effectiveness of lie detectors is debatable, meaning that these tests can potentially be fooled by individuals who either naturally manage their emotional responses well or have been trained to do so.
