Interdisciplinary approaches are crucial for addressing UPSC topics as they foster a holistic understanding of complex issues. Topics often intersect various fields such as politics, economics, society, and history. By integrating knowledge from different disciplines, aspirants can build a more comprehensive perspective on subjects like social justice or environmental policies. This multifaceted understanding enables nuanced analysis and better formulation of policies. Interdisciplinary approaches also enhance problem-solving skills, allowing candidates to connect theoretical concepts to practical realities, ultimately making them more effective future civil servants.
