Thanks, but No Thanks: Unpacking the Relationship Between Relative Power and Gratitude.

Power and gratitude are universal features of social life and impact a wide range of intra- and interpersonal outcomes. Drawing on the social distance theory of power, we report four studies that examine how relative power influences feelings and expressions of gratitude. An archival analysis of author acknowledgements in published academic articles ( = 1,272) revealed that low-power authors expressed more gratitude than high-power authors. A pre-registered experiment ( = 283) involving live conversations online found that having relatively low power caused increased feelings and expressions of gratitude after benefiting from a favor. Another pre-registered experiment ( = 356) demonstrated that increased interpersonal orientation among lower power individuals and increased psychological entitlement among higher power individuals drove these effects. Finally, an archival analysis of conversational exchanges ( = 136,215) among Wikipedia editors revealed that relational history moderated the effect of relative power on gratitude expression. Overall, our findings highlight when and why relative power influences feelings and expressions of gratitude.
