“…Children as young as preschoolers show social preferences favoring resource-rich individuals. In many recent studies, such preferences have been evoked through forced-choice judgments between two individuals who differ in the quality or quantity of their resources (Dunham, Newheiser, Hoosain, Merrill, & Olson, 2014;Horwitz, Shutts, & Olson, 2014;Li, Spitzer, & Olson, 2014;McCrink, Bloom, & Santos, 2010;Shutts, Brey, Dornbusch, Slywotzky, & Olson, 2016), even in the absence of explicit "rich" or "poor" labels (for judgments when such labels are used, see Roussos & Dunham, 2016;Sigelman, 2012). When asked questions such as which individuals are "nicer" (e.g., Li et al, 2014), which individuals they would rather befriend (e.g., Shutts et al, 2016), or which groups or individuals they like better (e.g., Horwitz et al, 2014), children as young as 4 and 5 favor the materially advantaged.…”
