Aspirants can analyze the cultural underpinnings of policy decisions in their UPSC essays by exploring how socio-cultural factors influence governance. Understanding local customs, traditions, and values can help candidates critique existing policies effectively. They should investigate how these cultural elements affect public perception, compliance, and implementation of laws. Referencing historical events or case studies that highlight cultural impacts on policy helps enrich the narrative. Additionally, applying theoretical frameworks such as cultural theory can aid in a comprehensive analysis. This depth of understanding will enable candidates to present well-rounded arguments in their essays, proving their analytical acumen.
