“…Future research should compare the explanatory power of this novel hypothesis against complementary hypotheses. Such complementary hypotheses may include (a) lack of empathy and, thus, antagonism (Back et al, 2013; Morf & Rhodewalt, 2001); (b) lack of self-insight and, thus, bragging (Palmer, Ramsey, Morey, & Gentzler, 2016; Van Damme, Deschrijver, Van Geert, & Hoorens, 2017); (c) hubristic pride and, thus, insulting body language (van Osch, Zeelenberg, Breugelmans, & Brandt, 2018); and (d) shameless self-promotion and, thus, envy in others (Rentzsch & Gross, 2015; Rentzsch, Schröder-Abé, & Schütz, 2015; Rentzsch, Schütz, & Schröder-Abé, 2011).…”
