Behavioralism is an approach in political science that emerged in the 1930s in the United States. It represented a sharp break from previous approaches in emphasizing an objective, quantified approach to explaining and predicting political behavior. Behavioralists seek to examine the behavior, actions, and acts of individuals and groups in different social settings and explain this behavior as it relates to the political system. Behavioralism is mainly concerned with examining the behavior, actions, and acts of individuals rather than the characteristics of institutions such as legislatures, executives, and judiciaries.

Behavioralism seeks a systematic inquiry of political behavior. To understand political behavior, behavioralism uses methods such as sampling, interviewing, scoring and scaling, and statistical analysis. Behavioralism attempts to explain political behavior from an unbiased, neutral point of view. It emphasizes the systematic understanding of all identifiable manifestations of political behavior.

Behavioralism is a movement in political science that insists on analyzing only observable behavior of political actors. It is an exercise in ensuring a value-free study of the discipline of politics. Behavioralism is also innovative because it changed the attitude of the purpose of inquiry. It uses strict methodology and empirical research to validate its study as a social science.

In summary, behavioralism is an approach in political science that seeks to provide an objective, quantified approach to explaining and predicting political behavior. It emphasizes the systematic understanding of all identifiable manifestations of political behavior and seeks to explain political behavior from an unbiased, neutral point of view.
