Age Differences in Social Decision-Making Preferences and Perceived Ability.

Decision-making often occurs in a social context but is typically studied as if it were an individualistic process. In the present study, we investigated the relationships between age, perceived decision-making ability, and self-rated health with preferences for social decision-making, or making decisions with others. Adults (N = 1,075; ages 18-93) from an U.S. online national panel reported their preferences for social decision-making, perceived changes in decision-making ability over time, perceived decision-making ability compared to age peers, and self-rated health. We report on three key findings. First, older age was associated with being less likely to prefer social decision-making. Second, older age was associated with perceiving one's ability to have changed for the worse over time. Third, social decision-making preferences were associated both with older age and perceiving one's ability to make decisions was worse than age peers. Additionally, there was a significant cubic function of age, such that older age was associated with lesser preferences for social decision-making until around age 50. Preferences then increased slightly with age until about age 60, after which older age was once again associated with lesser preferences for social decision-making. Together, our findings suggest that compensating for perceived lack of competence compared to other people one's age may motivate preferences for social decision-making across the life span.
