There has been some research, but no agreement, about the reliability of polygraph tests. Based on this research, suppose that a polygraph can detect 70% of lies, but incorrectly identifies 25% of true statements as lies. A company believes that 96% of its job applicants are trustworthy. The company gives everyone a polygraph test, asking "Have you ever stolen anything from your place of work?" Naturally, all the applicants answer "No," but the polygraph identifies some of those answers as lies, making the person ineligible for a job.
