 Another insight about democratic representation that comes from the literature on descriptive representation is the importance of contingencies. Here the work of Jane Mansbridge on descriptive representation has been particularly influential. Mansbridge recommends that we evaluate descriptive representatives by contexts and certain functions. More specifically, Mansbridge (1999, 628) focuses on four functions and their related contexts in which disadvantaged groups would want to be represented by someone who belongs to their group. Those four functions are “(1) adequate communication in contexts of mistrust, (2) innovative thinking in contexts of uncrystallized, not fully articulated, interests, … (3) creating a social meaning of ‘ability to rule’ for members of a group in historical contexts where the ability has been seriously questioned and (4) increasing the polity’s de facto legitimacy in contexts of past discrimination.” For Mansbridge, descriptive representatives are needed when marginalized groups distrust members of relatively more privileged groups and when marginalized groups possess political preferences that have not been fully formed. The need for descriptive representation is contingent on certain functions.
