In politics, representation describes how some individuals stand in for others or a group of others, for a certain time period. Representation usually refers to representative democracies, where elected officials nominally speak for their constituents in the legislature. Generally, only citizens are granted representation in the government in the form of voting rights; however, some democracies have extended this right further.
Hanna Fenichel Pitkin established four theories of representation in her philosophical writing on this subject:
Scientific research addresses some of the preceding forms of representation, but it also distinguishes dyadic and collective forms, which are explained below. Scientific research has also identified several alternative "models" or alternative versions of how dyadic representation might come about, especially including instructed delegate, responsible party, and trustee ones. The goal of scientific research is to develop systematic theory that accounts for the character of collective and dyadic representation and, in the latter case, for the conditions under which these alternative models arise.
British politician Edmund Burke in his 1774 Speech to the Electors at Bristol at the Conclusion of the Poll was noted for his articulation of the principles of representation against the notion that elected officials should be delegates who exactly mirror the opinions of the electorate:
It ought to be the happiness and glory of a representative to live in the strictest union, the closest correspondence, and the most unreserved communication with his constituents. Their wishes ought to have great weight with him; their opinion, high respect; their business, unremitting attention. It is his duty to sacrifice his repose, his pleasures, his satisfactions, to theirs; and above all, ever, and in all cases, to prefer their interest to his own. But his unbiased opinion, his mature judgment, his enlightened conscience, he ought not to sacrifice to you, to any man, or to any set of men living. These he does not derive from your pleasure; no, nor from the law and the constitution. They are a trust from Providence, for the abuse of which he is deeply answerable. Your representative owes you, not his industry only, but his judgment; and he betrays, instead of serving you, if he sacrifices it to your opinion.
Pitkin points out that Burke linked the district's interest with the proper behaviour of its elected official, explaining, "Burke conceives of broad, relatively fixed interest, few in number and clearly defined, of which any group or locality has just one. These interests are largely economic or associated with particular localities whose livelihood they characterize, in his over-all prosperity they involve."
