We have all heard about a lie detector or polygraph. You have taken a lie detector test because your boss thinks someone is stealing from the office. You are innocent, but unfortunately, you are informed that you have "failed" the polygraph test. Which of the following is not true about these tests? A. A polygraph cannot really detect the difference between arousal
caused by anxiety and that caused by lying.

are not necessarily guilty. D. While widely used by police and government agencies, polygraphs
often fail to identify the guilty.
