The cognitive approach to lie detection led to an average accuracy rate of 60.00%, 95% CI [56.42; 63.53] and a bias corrected average accuracy rate of 55.03%, 95% CI [48.83; 61.16]. 97-99% Outcome Confidence. If someone can pass a polygraph and an EyeDetect test on the same topic, then, as discussed by Meehl & Rosen, based on the statistical model called Bayes Theorem and the published accuracy of those technologies, there can be a 97 to 99% outcome confidence. That is a better outcome than the best lie detector test. . Starbucks pumpkin cream cold brew
