Default rules in investment decision-making : trait anxiety and decision-making styles

This study investigates the role of default options in the relationship between trait anxiety, and decision-making styles and financial decisions. One hundred and ninety-four participants were divided into three groups and subjected to three different conditions. Under each experimental condition, they had to decide whether to accept or reject investment proposals. In the first group, they had been enrolled in investment plans by default (opt-out condition), in the second group, they had not been automatically enrolled in these plans (opt-in condition), and in the third group they had to choose whether to enroll or not (control condition). The results showed that the investment decisions of anxious, avoidant, rational and dependent individuals could be facilitated by default options. In conclusion, using default options as a "nudge" can support specific groups of people to improve their financial decisions.
