Knowledge Questions: What They Are & How to Formulate Them
Theory of Knowledge (ToK) is unique to the IB Diploma and is consistently misunderstood by students. The core of ToK is the Knowledge Question (KQ)—a second-order question about how we know, rather than a first-order question about what we know. A first-order claim is a factual or subject-specific claim: 'DNA is the molecular basis of heredity.' A knowledge question is about the nature, limits, or justification of knowledge: 'To what extent can scientific models represent reality, or only approximate it?' The ToK essay presents six prescribed titles each exam session—your essay must address one of these titles directly. The essay is scored on Knowledge and Understanding (shown through KQs, WOKs/AOKs), Application (real-world examples and AOK examples), and Quality of Analysis. A common mistake: answering the title as if it were a subject essay. You must always zoom out to the epistemological question—'what does this reveal about how knowledge works?' Your thesis should directly answer the prescribed title with a qualified, defensible position.
