Totally agreed. I don't trust smart people who can't explain their ideas. It's not that I don't think they're right, it's that I don't think it's a good business idea to operate on faith. But also, being able to break a concept down increases the smart person's level of comprehension of their ideas - it's not only proof, it has tangible benefit.
