Critical thinking enhances the performance of candidates in UPSC by enabling them to analyze complex issues critically. It promotes the ability to evaluate evidence, formulate logical arguments, and make informed decisions, which are essential skills for both the Mains and the Interview stage. Moreover, critical thinking aids candidates in interpreting current affairs, understanding diverse perspectives, and addressing questions effectively during exams. As UPSC exams often require nuanced understanding, candidates who excel in critical thinking are likely to perform better in constructing well-reasoned answers.
