The objective of this article is to relate the intertemporal choices of 84 young adults, their gender and the bias towards the present. Through a quasi-experimental design using a choice test, it was found that 45% present bias towards the present in their choices. No statistically significant differences were found between age, time to choose and bias in the elections; on the other hand, significant differences were found regarding sex and bias towards the present. The results show that the participants' choices are not consistent.
