Choose the example that lets you analyse knowledge in action, not the one that only decorates your TOK paragraph.
Real-World Example or Textbook Example
Know the Difference
TOK students often ask whether an example has to be a real-world example. The better question is: does the example let you analyse knowledge in action? A real-world case is often stronger because it shows knowledge being produced, challenged, communicated, or misunderstood. But a textbook example can still work if you use it carefully and do not just repeat subject content.
When Textbook Examples Help
A real-world example usually has context, stakes, and uncertainty. For example, a medical guideline changing after new evidence shows how methods affect confidence. A historical interpretation changing after archival evidence shows how sources shape knowledge. A court case using forensic evidence shows how expert knowledge enters public decision-making. These cases are useful because they involve real people, institutions, methods, and consequences.
