In the research, the presence of heuristics and biases was evaluated in each group, such as overconfidence, representativeness, anchorage and procrastination. The results showed that both reason and emotion influence the participants’ answers of the bulk of the sample. Most people felt that their financial behavior is more rational than that of their peers. As expected, the study indicated significant differences in behavior according to gender, age, education and income.
