The two traditional justifications for bicameralism are that a second legislative chamber serves a legislative-review function (enhancing the quality of legislation) and a balancing function (checking concentrated power and protecting minorities). I furnish here a third justification for bicameralism, with one elected chamber and the second selected by lot, as an institutional compromise between contradictory imperatives facing representative democracy: elections are a mechanism of people’s political agency and of accountability, but run counter to political equality and impartiality, and are insufficient (...) for satisfactory responsiveness; sortition is a mechanism for equality and impartiality, and of enhancing responsiveness, but not of people’s political agency or of holding representatives accountable. Whereas the two traditional justifications initially grew out of anti-egalitarian premises (about the need for elite wisdom and to protect the elite few against the many), the justification advanced here is grounded in egalitarian premises about the need to protect state institutions from capture by the powerful few and to treat all subjects as political equals. Reflecting the “political” turn in political theory, I embed this general argument within the institutional context of Canadian parliamentary federalism, arguing that Canada’s Senate ought to be reconstituted as a randomly selected citizen assembly.

The world has surpassed three million deaths from COVID-19, and faces potentially catastrophic tipping points in the global climate system. Despite the urgency, governments have struggled to address either problem. In this paper, we argue that COVID-19 and anthropogenic climate change (ACC) are critical examples of an emerging type of governance challenge: severe collective action problems that require significant individual behavior change under conditions of hyper- partisanship and scientific misinformation. Building on foundational political science work demonstrating the potential for norms (...) (or informal rules of behavior) to solve collective action problems, we analyze more recent work on norms from neighboring disciplines to offer novel recommendations for more difficult challenges like COVID-19 and ACC. Key insights include more attention to (1) norm-based messaging strategies that appeal to individuals across the ideological spectrum or that reframe collective action as consistent with resistant subgroups’ pre-existing values, (2) messages that emphasize both the prevalence and the social desirability of individual behaviors required to address these challenges, (3) careful use of public policies and incentives that make individual behavior change easier without threatening norm internalization, and (4) greater attention to epistemic norms governing trust in different information sources. We conclude by pointing out that COVID-19 and climate change are likely harbingers of other polarized collective action problems that governments will face in the future. By connecting work on norms and political governance with a broader, interdisciplinary literature on norm psychology, motivation, and behavior change, we aim to improve the ability of political scientists and policy makers to respond to these and future collective action challenges.
