"Your take on others shows you for who you are." Endowed Professor economics of uncertainty Aurélien Baillon can read minds. Well, not exactly – but he gets pretty close. Baillon combines economy and psychology to wield a method that he coins the ‘economical truth serum’.
Why do we need a truth serum? Baillon explains: "Usually we judge the answers people give by means of a score, of a grade, and then we give feedback. We reward them whenever they give us the right answer. But if we ask a question that doesn’t have a right answer, then that’s beyond our control. How do you score that accurately? We’re talking about subjective questions here, ones that only you know the right answer to. For example, whether you’ve ever cheated during an exam."
