The reality is that detecting deception is never 100%. But with the help of this program and the scientific methodology used, you have a much higher likelihood of catching deception than that of untrained professionals (54%) or even the criminals (65%)! Dr. Ekman in his deep experience and study, has an accuracy of 95%. And properly understanding and applying his methodology, participants have increased their accuracy above 70 and 80%!
So the question is that are you more comfortable being more aware and clear about your decisions than guessing? The difference is that while both still share a risk of being wrong, by using the science, you aren’t guessing. Even having an accuracy of 60% is still 60% more certain than a 50:50 guess that isn’t supported by any evidence at all!
