“…Across fields researchers use different labels (e.g., "social value orientations," "social preferences," "self versus other orientation"), but they all refer to trait-like differences in preferences for distributions of outcomes to self and others in interdependent situations (e.g., De Cremer & Van Lange, 2001;Fehr & Fischbacher, 2002;Meglino & Korsgaard, 2004). Social dispositions have been shown to be stable personality traits with genetic roots (Wallace, Cesarini, Lichtenstein, & Johannesson, 2007) that are not affected by the dynamics of specific interactions (e.g., Eisenberg et al, 1999;Swap & Rubin, 1983).…”
