How does constructivism explain the formation of state interests?

Constructivism explains the formation of state interests by emphasizing the role of ideas, norms, identities, and social interaction. Unlike realism and liberalism, which often treat state interests as fixed or based on material factors, constructivism argues that interests are socially constructed and can change over time. This means that state interests are not predetermined but are shaped by shared beliefs, values, and understandings that emerge through interaction with other actors in the international system. Identities, in constructivist terms, are the understandings and expectations that states have about themselves and others. These identities are formed through social processes and influence how states perceive their roles and responsibilities in the world. For example, a state that identifies itself as a 'responsible stakeholder' may be more inclined to cooperate with international norms and institutions. In contrast, a state that sees itself as a victim of past injustices may be more likely to pursue revisionist policies. Norms are shared expectations about appropriate behavior. They can be formal, such as international laws and treaties, or informal, such as customary practices and diplomatic protocols. Norms shape state behavior by defining what is considered legitimate and acceptable in the international community. States internalize norms through a process of socialization, where they learn to conform to the expectations of others. For example, the norm against using chemical weapons has influenced states to refrain from using them, even though they may possess them. Social interaction is the process through which states communicate, negotiate, and build relationships. These interactions can lead to the diffusion of ideas, the construction of shared understandings, and the transformation of identities and interests. Through dialogue and cooperation, states can develop new perspectives on their own interests and the interests of others. For example, the European Union has played a significant role in shaping the identities and interests of its member states through a process of social interaction and norm diffusion. The EU has promoted shared values such as democracy, human rights, and the rule of law, which have influenced the domestic policies of its member states. Ultimately, constructivism posits that state interests are not simply a reflection of material capabilities or rational calculations, but are actively shaped by the social context in which states operate. By understanding the role of ideas, norms, identities, and social interaction, we can gain a deeper understanding of why states behave the way they do and how their interests can change over time.
