Abstract
In this article, two experiments were conducted and data collected from 270 questionnaires applied to undergraduate students at the Universidade de Brasilia, in order to study Fox and Tversky's comparative ignorance hypothesis (CIH) Fox e Tversky (1995). In the first experiment, we tested the CIH, and in the second, we investigated the effects of comparison between lotteries with different degrees of competence in the individual decision making process. The results obtained not only corroborate the CIH, but also deepen its comprehension, analyzing the effect of more than one parameter of comparison in the individual decision making process.
