UPSC Ethics, Integrity and Aptitude — GS Paper 4
What is GS Paper 4?
GS Paper 4 tests moral reasoning, not factual recall. It carries 250 marks with two sections:
Real question-count structure (2026 paper): Section A isn't 5-6 standalone questions — it's a smaller number of question GROUPS (6 in the real 2026 paper) each split into 2-3 sub-parts worth 10 marks/~150 words each, totaling 13 sub-parts across Section A. Section B is 6 full case studies at 20 marks/~250 words each, each with 2 sub-questions (a) and (b) answered together as one combined response, not two separate answers. 13×10 + 6×20 = 130+120 = 250, matching the paper's total exactly.
A real, current trend worth knowing: the 2026 paper's case studies leaned heavily on emerging-technology ethics — AI-generated academic evaluation, AI-driven predictive policing and its data bias, and biometric authentication excluding legitimate welfare beneficiaries all appeared as full case studies, alongside the more traditional consent/paternalism and corruption scenarios. This isn't a one-off — technology-mediated ethical dilemmas (who's accountable when an algorithm makes the call, not a person) are a growing share of what this paper actually tests, not just the classical trolley-problem-style theory.
