Polarization within Western societies escalates, as citizens increasingly distrust their governments and disagree with one another in an increasingly emotional way. Departing from a literature devoid of ideas to break this destructive trend, this paper presents a novel approach: While societies have evolved—becoming more diverse, individualized, and interconnected—democratic systems have remained unchanged, hence rooted in outdated structures. This misalignment drives the rise of political polarization. Through a comprehensive review of literature and data across OECD countries, this paper states the generality of the polarization problem, with the U.S. only as severest example. It introduces the concept of ‘partitioning representation’ of representing individuals as parts of non‐overlapping subsets of society, a form that fitted a bygone era of geographically and socially partitioned communities. The paper identifies three mechanisms through which the disjunction between this traditional form of representation and contemporary individualization leads to polarization: disconnection of voters from the political process, intra‐party dynamics that favor radicalization, and perverse incentives for political and media actors. Ultimately, breaking this destructive cycle requires rethinking how representation can work in a world that no longer conforms to the partitioned societies of the Western past. This calls for new forms of doing politics, empowering citizens to engage meaningfully with the political process and restoring the capacity for collective problem‐solving that is essential for democratic resilience in a new approach usefully called a ‘civil democracy’.
