William H. Riker

William Harrison Riker (September 22, 1920 – June 26, 1993) was an American political scientist who applied game theory and mathematics to political science.

Life and career

Early life

William Harrison Riker was born on September 22, 1920 in Des Moines, Iowa. He earned his bachelor's degree in economics at Indiana's DePauw University in 1942 and received his Ph.D at Harvard University in 1948. While a student at DePauw, he was initiated into the Delta Kappa Epsilon Fraternity.

Career

He took on a professorship at Lawrence University in Appleton, Wisconsin (then Lawrence College), where he published The Theory of Political Coalitions (1962). In 1962, he became the chair of the Political Science Department at the University of Rochester, where he remained chair until 1977, and remained active until his death.

He founded the now-mainstream field of positive political theory, which introduced game theory and the axiomatic method of social choice theory to political science. Bruce Bueno de Mesquita and Kenneth Shepsle in their memoir write that "These have proved crucial to predictive tests for political theory."

Among other contributions, he is known for work on the theory and history of federalism and on what he called "heresthetics" — the art of changing political outcomes without changing peoples' underlying preferences by manipulating the decision-making process, for example by changing the order in which decisions are made. In his book Liberalism Against Populism, he argued that the instability of majority rule, demonstrated in Arrow's Impossibility Theorem and the McKelvey-Schofield chaos theorem, meant that "populist" interpretations of democracy as implementing a collective will of the people were untenable. Instead, democratic leaders aimed to build disparate coalitions; a piece of successful coalition-building could cause realigning elections, in which blocs of voters swiftly changed their allegiance.

Concerning political coalition for the benefit of minorities, he argued that the larger the coalition, the shorter-lived it is.

The William H. Riker Prize for excellence in undergraduate teaching is awarded by the University of Rochester bi-annually in his honor. The Political Economy section of the American Political Science Association awards an annual book prize in his name as well.
