Behaviouralism (or 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 explain and predict political behaviour. It is associated with the rise of the behavioural sciences, modeled after the natural sciences. Behaviouralism claims it can explain political behaviour from an unbiased, neutral point of view. Behaviouralists seek to examine the behaviour, actions, and acts of individuals – rather than the characteristics of institutions such as legislatures, executives, and judiciaries – and groups in different social settings and explain this behavior as it relates to the political system.
