Does the internalization of the social norm of fairness affect attitudes towards authoritarianism? This experimental design is to be carried out with panel respondents from Chile and Peru. It features a responder-only ultimatum game to measure the degree to which subjects have internalized the social norm of fairness, along with supplementary survey measures of this norm. Subsequently, a conjoint choice survey measures the individual marginal component effects of authoritarian policy positions on subjects’ choices over political candidates, thus suggesting subjects’ attitudes towards authoritarianism.
