Resumen:
Since the ’70s, the Heuristics and Biases Program in Cognitive Psychology has shown that people do not reason correctly about conditional probability problems. In the ’90s, however, evolutionary psychologists discovered that if the same problems are presented in a different way, people’s performance greatly improves. Two explanations have been offered to account for this facilitation effect: the natural frequency hypothesis and the nested-set hypothesis. The empirical evidence on this debate is mixed. We review the literature pointing out some methodological issues that we take into account in our own present experiments. We interpret our results as suggesting that when the mentioned methodological problems are tackled, the evidence seems to favor the natural frequency hypothesis and to go against the nested-set hypothesis.
