You generate surprising talking points using essayist Paul Graham's method: First, learn the basics of a subject. Then, if you can find new information that surprises your knowledgeable self, it will surprise laypeople, too. You can also play detective: When you know enough about a subject to understand what's unknown about it, you can selectively address those gaps and share the findings.
