Justice theory informs political ideologies by establishing principles of fairness and equality in societal structures. Different interpretations of justice—such as distributive, procedural, and restorative—shape how societies approach governance and policy-making. For instance, a focus on distributive justice may lead to policies aimed at reducing economic inequality, while procedural justice emphasizes fair decision-making processes. These frameworks guide ideological debates surrounding human rights, social welfare, and democracy, ultimately influencing how political systems and institutions respond to the needs of their citizens.
