=+16. U.S. Customs and Border Protection has been testing automated kiosks that may be able to detect lies.

all/) One measurement used (among several) is involuntary eye movements. Using this method alone, tests show that it can detect 60% of lies, but incorrectly identifies 15% of true statements as lies. Suppose that 95% of those entering the country tell the truth. The immigration kiosk asks questions such as “Have you ever been arrested for a crime?” Naturally, all the applicants answer “No,” but the kiosk identifies some of those answers as lies, and refers the entrant to a human interviewer.
