How to Think About Social Identity

Introduction

  • Social Identity: Integral to understanding various political phenomena like voting, redistribution, and conflict.
  • Key Questions:
    • What does identifying with a social group mean?
    • Are group attachments tied to material or nonmaterial benefits?
    • When and how do identities impact behaviors?

Concepts and First Principles

  • Social Identity Theory:
    • Developed by Henri Tajfel and associates.
    • Focuses on the psychological need for esteem and the role of social categorization.
    • Emphasizes that social identities can drive behaviors through both material and psychic rewards.

Rational Choice and Social Identity

  • Rational Choice Models:
    • Incorporate social identity by expanding utility functions to include social norms and identity-driven behaviors.
    • Noteworthy works by Akerlof & Kranton and Shayo are highlighted.

Recent Literature and New Directions

  • Voting and Political Behavior:

    • Dominated by questions of whether motivations are instrumental (material-driven) or expressive (identity-driven).
    • Studies show strategic use of identity in campaigns can impact voting behavior.
  • Nationalism and Identity:

    • Multiple perspectives exist, including idealist, materialist, and ethno-symbolic.
    • National identity can be entrenched and impact political actions beyond material calculations.

Violence and Conflict

  • Role of Identity in Conflict:
    • Ethnic and national identities often play a significant role in civil wars and other conflicts.
    • Instrumentalist vs. primordialist debate persists in explaining identity-driven conflict.

Social Identity and Public Goods

  • Tax Compliance and Public Goods:
    • Social identity and norms influence behaviors like tax compliance and public goods provision.
    • Frequent emphasis on overcoming free-rider problems through community norms.

Conclusion

  • Interdisciplinary Approach:
    • Need for integrated approaches combining strategic, cultural, and psychological insights.
    • Important to understand the role of elites, social norms, and group status in shaping identity-driven behaviors.

Implications for Policy and Research

  • Policy Design:
    • Considerations of social identity crucial for effective policy making.
    • Examples from counterinsurgency strategies in Iraq and Afghanistan highlight the importance of identity considerations.
