Question

reflection
if polygraph data is not admissible in court, do you think it should be allowed to be used as an interrogation method or employment screening? why or why not?

Explanation:

Polygraphs measure physiological responses like heart rate and sweating, which can be triggered by anxiety, stress, or nervousness unrelated to deception—they do not directly detect lying, leading to high rates of false positives and false negatives. Since they are not scientifically validated as reliable tools for determining truthfulness, allowing their use in interrogations or employment screening would risk unfair outcomes: innocent people could be wrongfully suspected or denied jobs, while deceptive individuals might avoid detection. Additionally, their use raises ethical concerns about privacy and potential coercion, as individuals may feel pressured to take them with no guarantee of accurate results.

Answer:

Polygraph data should not be allowed for interrogations or employment screening. This is because polygraphs do not reliably detect deception (they measure general stress responses that can stem from non-deceptive anxiety), leading to frequent false results that would enable unfair, unethical, and inaccurate judgments in both legal and employment contexts.
