 Given these changes, it is necessary to revisit our conceptual understanding of political representation, specifically of democratic representation. For as Jane Mansbridge has recently noted, normative understandings of representation have not kept up with recent empirical research and contemporary democratic practices. In her important article “Rethinking Representation” Mansbridge identifies four forms of representation in modern democracies: promissory, anticipatory, gyroscopic and surrogacy. Promissory representation is a form of representation in which representatives are to be evaluated by the promises they make to constituents during campaigns. Promissory representation strongly resembles Pitkin’s discussion of formalistic representation. For both are primarily concerned with the ways that constituents give their consent to the authority of a representative. Drawing on recent empirical work, Mansbridge argues for the existence of three additional forms of representation. In anticipatory representation, representatives focus on what they think their constituents will reward in the next election and not on what they promised during the campaign of the previous election. Thus, anticipatory representation challenges those who understand accountability as primarily a retrospective activity. In gyroscopic representation, representatives “look within” to derive from their own experience conceptions of interest and principles to serve as a basis for their action. Finally, surrogate representation occurs when a legislator represents constituents outside of their districts. For Mansbridge, each of these different forms of representation generates a different normative criterion by which representatives should be assessed. All four forms of representation, then, are ways that democratic citizens can be legitimately represented within a democratic regime. Yet none of the latter three forms representation operates through the formal mechanisms of authorization and accountability. Recently, Mansbridge (2009) has gone further by suggesting that political science has focused too much on the sanctions model of accountability and that another model, what she calls the selection model, can be more effective at soliciting the desired behavior from representatives. According to Mansbridge, a sanction model of accountability presumes that the representative has different interests from the represented and that the represented should not only monitor but reward the good representative and punish the bad. In contrast, the selection model of accountability presumes that representatives have self-motivated and exogenous reasons for carrying out the represented’s wishes. In this way, Mansbridge broadens our understanding of accountability to allow for good representation to occur outside of formal sanctioning mechanisms.
