A few times, I've come across Stackoverflow questions on technical topics I'm not very familiar with, and the question makes no sense to me (there are clear spelling, grammatical, and consistency errors). But there's an answer, and a comment exchange that seemed to resolve the question. So, I conclude, it's just my unfamiliarity prevents me from seeing through those errors.

A related phenomena is seeing fundamental errors in a newspaper article on a topic you're expert in... but believing articles on topics you're not familiar with.

This can operate as a partial turing test: a gradient for iteration.
