The reading passage contends that lie detectors that are instrument to pinpoint a truth is a good way to indicate a person's deceptive statements. On the other hand, the lecturer brings up several points that contradict the argument.
Firtst, the speaker argues that the accuracy of lie detector is lower that people expect. This is because specific physiological changes might not be triggered only by lying. When people ware examined, they might be so nervous, which lead to bioligical response such as sweating or higher heart rate. This cast doubt on the reading, which states that polygraph instruments are very accurate since they catch all the biological changes.
The other point made in the lecture is that lie detector tests are sbjective rather that objective. One significant reason is that examiner is alone in the test room, and, thus, he might affect the behavior of examinee. Moreover, examinee who is so intimidated might not tell the truth, which leads to incorrect results. This refutes the reading passage's assertion that lie detectors offer objective results because examination was processed carefully such as careful questions and skillful examiners. | |
