“…This analysis suggests that a leader's prototypicality of the group in particular should be tied to leadership effectiveness because individuals that are more representative of the group are more influential and attractive (Hogg, 1992;van Knippenberg, Lossie, & Wilke, 1994). 1 The proposition that leader prototypicality is a determinant of leadership effectiveness is supported by an increasing number of studies showing, for instance, that prototypical group members are more likely to emerge as leaders (Fielding & Hogg, 1997;van Knippenberg, van Knippenberg, & van Dijk, 2000) and that groupprototypical leaders are more influential and effective (Hains, Hogg, & Duck, 1997;Hogg, Hains, & Mason, 1998;Platow & van Knippenberg, 2001;Platow, van Knippenberg, Haslam, van Knippenberg, & Spears, 2002;. Evidence for the importance of leader prototypicality for leader effectiveness and emergence was found in studies using different paradigms, different operationalizations of prototypicality, and different measures of leadership effectiveness.…”
