The Good Council: Deliberating Inequality in a Field Experiment

This paper investigates how participation in a citizens’ assembly affects individuals’ redistributive pref-erences and (perceived) role in democracy. We implement a pre-registered field experiment embedded ina real-world citizens’ assembly on wealth inequality in Austria. Using a three-group-design comparingassembly participants, non-selected volunteers, and a population sample, we isolate the causal effects oftaking part in a citizens’ assembly from self-selection into participation. We find that while participat-ing in the citizens’ assembly substantially improves factual knowledge about the wealth distribution and promotes convergence around specific tax policy proposals, notably a EUR 1 million allowance, it has nomeasurable effect on political efficacy or broader civic engagement. We also document significant political self-selection: individuals willing to participate in the citizens’ assembly were already more engaged andsupportive of redistribution than the general population. These findings suggest that while deliberative formats can foster informed convergence on policy proposals, their ability to mobilize broader publics is limited – especially if they primarily engage the already supportive and, as in this case, lack institutional anchoring that might facilitate spillover into more institutionalized political arenas.
