How did neoinstitutionalism change the study of political science in the 1980s?

In the 1980s, neoinstitutionalism emerged as a "postbehavioralist" movement that fundamentally reshaped political science by bridging the gap between traditionalist and behavioralist approaches.1

While traditionalists previously focused on formal rules and behavioralists prioritized the actions of individual actors, neoinstitutionalism argued that studying individual behavior without accounting for institutional constraints resulted in a skewed understanding of political reality. By "bringing the state back in," scholars sought to examine how institutional structures, norms, and rules shape individual choices.12

This shift introduced three primary methodological streams:
* Rational choice institutionalism: Uses game theory and economic modeling to view institutions as systems of incentives and rules.1
* Sociological institutionalism: Emphasizes how institutional cultures, myths, and symbols are socially and culturally constructed.1
* Historical institutionalism: Analyzes how historical legacies, path dependence, and long-term constraints influence political outcomes.1

Ultimately, this movement allowed political scientists to integrate the quantitative rigor of behavioralism with a renewed focus on the organizational basis of politics.12
