Do nerves affect the results of a polygraph test?
No. It is expected that all people who undergo a polygraph test will be nervous whether they intend to answer questions truthfully or not. An examiner will look for action specific responses over and above the examinee’s heightened level of nervousness or anxiety. Typically an examinee remains nervous throughout the entire testing process not at one individual question. If nerves affected the result of a polygraph test, then nobody would ever pass a test.
