Past research on gratitude assumes that norms of reciprocity are incompatible with personal relationships as they are based on the rigid normative expectations characteristic of market-based exchange. Challenging this assumption, the present investigation demonstrates the importance of recognizing that norms of reciprocity take a less rigid and more tacit form in the case of personal relationships. Using a vignette-based experiment, Study 1 (N = 200) demonstrated that when expectations to reciprocate are framed in ways that reflect their normative character rather than are portrayed as based on self-interested individual expectations, this is associated with greater likelihood of helping, enhanced gratitude, and more positive personality impressions. In an online game, Study 2 (N = 108) showed that players reciprocate less money to their exchange partner in the presence as compared with the absence of self-interested individual expectations for return. Assessing real life helping among friends, Study 3 (N = 128) revealed that indebtedness is predictive of helping and that indebtedness and gratitude promote relationship closeness in contrasting ways.
