Reflectivism

Reflectivism is an umbrella label used in International Relations theory for a range of theoretical approaches which oppose rational-choice accounts of social phenomena and positivism generally. The label was popularised by Robert Keohane in his presidential address to the International Studies Association in 1988.^[1] The address was entitled "International Institutions: Two Approaches", and contrasted two broad approaches to the study of international institutions (and international phenomena more generally). One was "rationalism", the other what Keohane referred to as "reflectivism". Rationalists — including realists, neo-realists, liberals, neo-liberals, and scholars using game-theoretic or expected-utility models — are theorists who adopt the broad theoretical and ontological commitments of rational-choice theory.
