<i>I now know that it's more nuanced than that.... X is just a pretence. [sic]</i><p>I think that it is even more nuanced than you propose. Often non-geeks <i>are</i> interested in the subject, but may not have sufficient interest or mental energy required for significant, structured thought into the subject. That is the kind of thought that geeks are accustomed to, but to non-geeks, that's what they do at work, not for pleasure (exceptions abound, though. For example, "non-geeks" often put careful thought into sports. Maybe they should be called "sports-geeks").<p>I regularly am asked questions about technical matters outside of my expertise. I try to draw some logic into the matter, break it down, and come up with a simple, reasonable, and probably accurate answer. If required, the asker is often intelligent enough to come up with a similar answer - or at least an equally plausible one. But they don't want to, so they ask me. And that's okay. If I don't want to think about, I'll tell them I don't know.
