With the use of questionnaires to collect data and logit regressions, the results show that Academic Performance (AP) has a direct relationship with the rationality of choices and alters cognitive biases in decision making. In this sense, students with higher AP made more rational choices than students with lower AP, which means a lower susceptibility to cognitive biases. %K prospect theory %K rationality of choices %K academic performance %K cognitive biases %K behavioral finance. %U http://www.anpad.org.br/periodicos/arq_pdf/a_1374.pdf
