In the third and final episode of the cognitive bias series, Ricardo discusses two types of opposed behaviours: the Dunning Kruger effect and the Impostor Syndrome. Both are related to the actual competence x competence that we think we have. At Dunning Kruger, we find ourselves more competent than we are. In impostor syndrome, we have a hard time admitting the real competence we have. Both generate a loss of connection with reality that hinders and alters our decision making and perception of reality.
