P. C. Wason y Thomas. S. Kuhn: Anomalías en la Lógica?

From the theoretical frame proposed by Kuhn, it is possible to interpret that Wason Selection Task represents an anomaly in cognitive science and psychology of reasoning. In this paper, we try to demonstrate that it is not and, with this aim, we offer an explanation, in terms of classic logic, about the unusual outcomes that we habitually observe when several experimental subjects execute Wason task. In the same way, we check flexible deontic logic theory, an approach that interprets individuals mayority selections in the above mentioned exercise by means of new logic, parallel to the traditional one. Finally, we show that it is not necessary to assume this new logic to understand subjects choices in Selection Task.
