The relevance of scientific temper in UPSC examination topics lies in its emphasis on rationality, evidence-based reasoning, and critical thinking. It helps candidates approach issues objectively, particularly in subjects like Science and Technology, Environment, and Social Issues. Embracing a scientific temper enables aspirants to analyze data, evaluate arguments, and formulate informed opinions, which are crucial for both the Preliminary and Mains examinations. Additionally, it aligns with the ethos of the Indian Constitution, promoting a culture of logical inquiry and skepticism necessary for a responsible civil servant.
