Prosociality can create social connections that increase well-being among both givers and recipients, yet concerns about how another person might respond can make people reluctant to act prosocially. Existing research suggests these concerns may be miscalibrated such that people underestimate the positive impact their prosociality will have on recipients. Understanding when miscalibrated expectations emerge in development is critical for understanding when misplaced cognitive barriers might discourage social engagement and for understanding when interventions to build relationships could begin. Two experiments asking children (aged 8-17, Experiment 1; aged 4-7, Experiment 2) and adults to perform the same random act of kindness for another person document that both groups significantly underestimate how "big" the act of kindness will seem to recipients, and how positive their act will make recipients feel. Participants significantly undervalued the positive impact of prosociality across ages. Miscalibrated psychological barriers to social connection may emerge early in life.
Public Significance StatementProsociality tends to increase well-being among those performing the prosocial action as well as among those receiving the action. And yet, people may be somewhat reluctant to act prosocially out of concerns about how another person might respond. In two experiments involving children (4-7 years old), adolescents (8-17 years old), and adults, we find that people's concerns tend to be systematically miscalibrated such that they underestimate how positively others will respond to their prosocial act. The degree of miscalibration is not moderated by age. This suggests that miscalibrated social cognition could make people overly reluctant to behave prosocially, that miscalibrated expectations emerge early in development, and that overcoming these social cognitive barriers could potentially increase well-being across the lifespan.
