“…However, most of these studies use highly stylized forms of communication where players send signals (e.g., "red" or "blue") over computers but do not actually talk face to face (for an exception see Myers, 2012a). Finally, Karpowitz, Mendelberg, and Shaker (2012) have subjects deliberate and decide between different rules for redistributing income that they will earn in a subsequent, unknown experimental task (see also Karpowitz et al, 2012, Mendelberg, Karpowitz, & Goedert, 2013. In this deliberation task, which loosely mirrors Rawls's original position (1971), groups' decisions can be judged as more or less just based on how generously they decide to redistribute income to the poor, though such judgment obviously requires a commitment to a particular substantive conception of justice (such as Rawls's; see also Guttmann & Thompson, 1996).…”
