“…There are many ways to get to leadership by measuring different kinds of variables from various sources, including data that is archival-historiometric (Barnes, Dang, Leavitt, Guarana, & Uhlmann, 2016;Friedrich et al, 2014;Simonton, 2003Simonton, , 2009, neurological (Waldman, Wang, & Fenters, 2016), genetic (De Neve, Mikhaylov, Dawes, Christakis, & Fowler, 2013), hormonal (van der Meij, Schaveling, & van Vugt, 2016, facial (Todorov, Mandisodza, Goren, & Hall, 2005), economic (Zehnder, Herz, & Bonardi, in press), big data (Tonidandel, King, & Cortina, in press), or agent-based simulation data (McHugh et al, 2016).
