“…Importantly, however, having a dominant leader is also associated with a specific range of costs and, accordingly, followers must carefully trade these costs against the benefits of the better enforcement of collective action. One key source of costs comes from an association between physical dominance-related traits and selfishness: Physically stronger individuals are more self-interested (Petersen, Sznycer, Sell, Cosmides, & Tooby, 2013), more supportive of inequality and oppression (Price, Kang, Dunn, & Hopkins, 2011), and people tend to view dominance-related physical traits as indicative of dishonesty and untrustworthiness (Buckingham et al, 2006;Jensen & Petersen, 2011;Perrett et al, 1998). While dominant leaders might be better able to "extract" aggressive collective action from group members, they might also be more inclined to use their position as a means to exploit the collective for their own benefit (see also von Rueden, Gurven, Kaplan, & Stieglitz, 2014).…”
