When a polygraph test is judged inconclusive, this is no reflection on the examinee. Rather, such a judgment means that the test has failed to show whether the examinee was truthful or untruthful. Nevertheless, employers will sometimes refuse to hire a job applicant because of an inconclusive polygraph test result. Which of the following conclusions can most properly be drawn from the information above? ['Most examinees with inconclusive polygraph test results are in fact untruthful.', 'An inconclusive polygraph test result is sometimes unfairly held against the examinee.', 'A polygraph test indicating that an examinee is untruthful can sometimes be mistaken.', 'Some employers have refused to consider the results of polygraph tests when evaluating job applicants.']
