“They” not “It”: Understanding Group Behavior Through Methodological Individualism

Understanding Group Behavior Through Methodological Individualism

In his thought-provoking 1992 article “Congress is a ‘They,’ not an ‘It’: Legislative Intent as Oxymoron” published in the International Review of Law and Economics, Kenneth Shepsle, a political scientist from Harvard University, challenges the concept of legislative intent as an oxymoron. He argues that just like military intelligence and jumbo shrimp, the idea of a collective intent within a group is contradictory.

Building on Shepsle’s argument, it becomes evident that any form of group behavior, be it legislative intent, market intent, or Supreme Court intent, should be analyzed through the lens of methodological individualism. This approach emphasizes that the dynamics of a group are best understood by examining the actions of the individuals comprising the group.

Methodological individualism does not negate the existence of groups but rather asserts that individual behavior is the focal point of analysis. When we attribute achievements or actions to a group, such as saying “the firm produced the pencil,” it is essential to recognize that the group’s actions stem from the behaviors of its individual members. The group’s constitution emerges from the aggregate behavior of its constituents.

Moreover, the relationship between individual behavior and group constitution is reciprocal. As Adam Smith elucidates in The Theory of Moral Sentiments, our interactions with others shape our understanding of appropriate behaviors and societal norms. This mutual influence underscores the organic nature of group behavior.

Applying methodological individualism to economic analysis reveals a fundamental distinction between economic theories and accounting identities. Markets do not compel individuals to act in a certain way; rather, economic outcomes arise from voluntary interactions and choices made by individuals seeking to pursue their self-interest. The emergent nature of market behavior underscores the active role individuals play in shaping economic outcomes.

It is crucial to recognize that mechanistic approaches to understanding group behavior overlook the organic and emergent nature of interactions among individuals. Methodological individualism offers a nuanced perspective that highlights the dynamic interplay between individual actions and collective outcomes.

While there may be challenges in applying a non-individualist approach to group behavior, the observed contradiction between rational models and irrational group behavior warrants further exploration. By embracing methodological individualism, we can gain deeper insights into the complex dynamics of group behavior across various domains.
