Undervaluing the positive impact of kindness starts early.

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.
