In this paper, we investigate the capability of inferring conditional probabilities in a representative sample of the German population. Our results show that only a small fraction of the population responds consistently with Bayes'' rule. Instead, most individuals either neglect the base probability, or the arrival of new information, in their responses. The probability to give normatively correctanswers decreases with the level of education.
