Robert Dahl (1915–2014)

Dahl argued that power in modern democracies is dispersed among competing groups, not concentrated in a single elite. Who Governs? Democracy and Power in an American City (1961) — a study of decision-making in New Haven, Connecticut — found that different groups prevailed on different issues: business interests dominated economic policy, political professionals dominated party nominations, and neighbourhood groups influenced urban development. No single group controlled all domains. The result challenged both Marxist class analysis (which predicted that economic elites would dominate all arenas) and C. Wright Mills’s power-elite thesis (The Power Elite, 1956, which argued that a cohesive military-industrial-political elite controlled American society). Dahl’s alternative: pluralist democracy — a political system in which power is fragmented, multiple groups compete, and no group achieves dominance across all issues. The concept of “polyarchy” — Dahl’s term for real-world approximations of democracy, distinguished from the unattainable ideal — became a standard framework in comparative politics.

Life

Born 17 December 1915 in Inwood, Iowa. Undergraduate at the University of Washington (BA, 1936). PhD in political science at Yale (1940). Served in the U.S. Army during the Second World War. Returned to Yale, where he spent his entire career — Sterling Professor of Political Science (1963–86), emeritus until his death. The Yale political science department under Dahl was one of the strongest in the world, and Dahl’s combination of empirical method and democratic theory shaped the department’s identity.

Dahl was a methodological innovator: he insisted that claims about power must be tested empirically — by studying actual decisions and identifying who prevails — rather than inferred from social position or institutional structure. This “decisional” method was both the strength of his approach (it produced concrete findings) and the source of its most sustained critique (it may miss power that operates through agenda-setting and non-decisions rather than through overt conflict).

Died 5 February 2014 in Hamden, Connecticut, at ninety-eight.

Pluralist democracy and polyarchy

Pluralism. Dahl’s pluralist theory: in a modern democracy, power is dispersed among multiple groups — business, labour, ethnic communities, professional associations, neighbourhood organisations, political parties. No single group dominates all domains. Power is issue-specific: the groups that prevail on economic policy are not necessarily the groups that prevail on education, foreign policy, or urban planning. The competition among groups is the mechanism through which democratic responsiveness is achieved — not through direct popular sovereignty (which is practically impossible in a large polity) but through the ongoing contestation of organised interests.

Polyarchy. Polyarchy: Participation and Opposition (1971) distinguishes between democracy (the ideal: rule by the people) and polyarchy (the real approximation: a political system characterised by broad participation and open contestation). A polyarchy is not a perfect democracy; it is a system in which multiple groups can organise, compete for influence, and contest government decisions. The two dimensions — participation (who can take part) and contestation (how freely groups can oppose the government) — define a space in which actual political systems can be located. The concept allowed comparative analysis: different countries approximate polyarchy to different degrees, and the movement toward polyarchy (democratisation) can be studied empirically.

Who Governs? The 1961 study of New Haven examined three policy areas — urban renewal, public education, and political nominations — and found that different groups dominated in each. The finding was presented as evidence against the power-elite thesis: if a single elite controlled New Haven, it would prevail across all three domains. The methodology — studying actual decisions — became known as the “decisional approach” and set the standard for empirical power analysis in the 1960s and 1970s.

Where Dahl stops

The decisional approach — studying who prevails in actual decisions — was challenged by Peter Bachrach and Morton Baratz in “Two Faces of Power” (1962): power operates not only through winning decisions but through controlling the agenda — preventing certain issues from being decided at all. The “non-decision” is a form of power that the decisional method cannot detect, because it looks only at decisions that were made, not at decisions that were suppressed. Steven Lukes extended the critique in Power: A Radical View (1974), arguing for a three-dimensional view of power that includes the capacity to shape people’s preferences and perceptions — so that they do not even recognise their own interests. Each critique deepens the concept of power beyond what Dahl’s empirical method can measure: from decisions, to agenda-setting, to the formation of preferences. Dahl acknowledged the critiques but maintained that his empirical approach, while incomplete, was more rigorous than the alternatives.

The pluralist framework has been pressed on the question of inequality. Dahl’s pluralism assumes that all groups can organise and compete effectively, but the capacity to organise is itself unequally distributed — wealthier, better-connected, and more established groups have systematic advantages in the pluralist competition. E. E. Schattschneider’s observation — “The flaw in the pluralist heaven is that the heavenly chorus sings with a strong upper-class accent” — captures the objection: pluralist democracy may be formally open but substantively tilted. Dahl’s later work (How Democratic Is the American Constitution?, 2001; On Political Equality, 2006) increasingly acknowledged that economic inequality undermines the conditions for genuine polyarchy.
