Superordinate inclusiveness stems from social comparisons about relative category size

Evidence

As theory stipulates (Brewer, 1993) and evidence supports (Hornsey & Hogg, 1999), group members identify with and prefer the more exclusive subgroup particularly as the superordinate category’s inclusiveness increases. Moreover, group inclusiveness originates from social comparisons (Brewer, 1991; Leonardelli et al., 2010), and, in particular, the size of one category relative to another. However, what has not been addressed, but has important implications for group identification in nested category contexts, is what social comparison is defining the superordinate category’s inclusiveness. We distinguish between two such comparisons: (1) vertical and (2) horizontal comparisons. — Roderick M. Kramer, Geoffrey J. Leonardelli, Robert W.
