Polygraph tests (lie-detector tests) are often routinely administered to employees or prospective employees in sensitive positions. A polygraph test will label subjects + (positive) if it determines the subject is lying and - (negative) if it determines the subject is not lying. Subjects can either be lying or not lying (truthful). According to studies of polygraph reliability, the probability that the polygraph will test + (positive) given/conditional that the subject is actually lying is 0.88. The probability that the polygraph will test - (negative) given the subject is telling the truth (not lying) is 0.84. Assume that 90% chance a subject is telling the truth (10% chance of lying).
