Pretty simple. Ask them. But not just any questions. And not just because you happen to not feel like doing the research to find the answer. Ask questions that spark conversations. That are inquisitive in that childlike manner... with wonderment. Ask questions that will help you figure things out. That will press the person you're asking to think deeper and ask their own questions. Questions lay the groundwork for solving most creative problems - so the better the question, the better the solution.
