A person's questions reveal the boundaries of their curiosity—what they're willing to admit they don't understand, which territories of thought they consider worth exploring. Answers, by contrast, can be borrowed, memorized, or performed, but a genuinely useful question must originate from the questioner's own mind. When you sit across from someone at dinner and they ask you *how* you came to believe something rather than *whether* you believe it, you're glimpsing their actual intellectual character. This is why job interviews that focus on how candidates would handle novel problems matter more than their rehearsed accomplishments: questions show us who thinks.
