“…Social comparisons serve as a fundamental mechanism for evaluating the self in relation to others (Festinger, 1954), thus providing input for individual processes of self-esteem updating. Nine of the analyzed studies directly test for social comparison (Greitemeyer, 2016;Hanna et al, 2017;Kang, Chung, Mora, & Chung, 2013;Liu et al, 2017;Stapleton, Luiz, & Chatwin, 2017;Vogel, Rose, Okdie, Eckles, & Franz, 2015;Vogel et al, 2014;Wang, Wang, Gaskin, & Hawk, 2017;Yang, Holden, & Carter, 2018). The results of another four studies can be interpreted in the light of social comparison theory (Chen et al, 2016;Gonzales & Hancock, 2011;Strubel, Petrie, & Pookulangara, 2018;Wang, Yang, & Haigh, 2017).…”
