It is well established that certain autonomic responses such as heart rate, perspiration, and respiration change under stress. in view of the fact that people generally have stronger autonomic responses when lying than when telling the truth, it follows that the polygraph would be a foolproof approach to lie detection. which statement best explains why the polygraph is not more widely used in courtrooms and in testing of job applicants?

Psychological arousal is very simimal for several emotions, so it is not always reliable for the polygraph to distinguish one emotion reaction from another. For instance guilt from other reactions.

Explanation:

The polygraph can most certainly determine if a person is nervous or not, because the nervous system reacts under testing situations, as well as other body reactions. This is not sufficient enought to deternmine wether someone is lying or not, is guilty or not. Someone can be nervous, and the polygraph can identify it, but this does not neccesarily mean a person can be found guilty.

the historians cited in the article all agree with one another about the cause of the civil war. despite coming from different backgrounds and cultures, the historians agree that slavery was the root cause of the civil war. the fact that all these historiansgenerally agree with one another makes their shared viewpoints more reliable and valid, especially because the historians have different backgrounds and all work for the well-respected institutions of howard university, clemson university, and the university of colorado.
