If you're dealing with competent people and you admit your ignorance, the competent people never judge you harshly for that as long as you've been paying attention. So in my classes, for example, people were often afraid to ask questions. And so sometimes I would point to people and ask them if they had a question, especially the quieter types. And they'd be afraid to ask the question because they're revealing their ignorance and they would assume they're the only person in the room that's that ignorant, but they're not because if they were paying attention and they had a question, the probability that half the class had that question was really high. That's different if you're not paying attention. And so you can be ignorant, you can be an ignorant newbie and you can even ask the questions that are necessary to ask in that position and sort of reveal your inadequacy. And as long as you're dealing with competent people and you've been paying attention, they're just going to answer your questions. And then you only have to be ignorant once.
