Professor Randy Stevenson’s research focuses on mass political behavior, cabinet formation, and institutional design in Western democracies. His recent work focuses on how voters in multiparty democracies (in which coalition cabinets usually form) manage the complexity of those systems by employing simplifying heuristics. This includes studies of how such voters prospectively attribute responsibility for multiparty policy making, retrospectively attribute responsibility for economic performance, form left-right images of parties, create and maintain multiparty partisan identities, develop and maintain political interests and knowledge, and keep track of the extent to which different parties are allies or enemies.
