First, a man should not have any power over that which he does not understand (deeply).

Second, patience as a virtue is very important here, because developing expertise in an area takes time and effort. One must be devoted.

Following from this manner comes, once again, Charlie Munger's principle... Do not form an opinion if you do not understand multiple perspectives.

"Yes, but I don't have the time to do my own research." is criticism on this principle, I respond with: "But if you aren't even willing to make time to form your opinion based on logic and deep understanding, is it worth having an opinion at all?"

Like Marcus Aurelius said: "The opinion of ten thousand men is of no value if none of them know anything about the subject."

You don't ask a lawyer to perform surgery on you, or even to explain it to you theoretically, he does not know anything about this. In the same way, a civilian should not be asked to teach politics.

From the same manner, do not judge before understanding. This is also what Mortimer J. Adler & Charles van Doren advocate: "You must say with reasonable certainty 'I understand' before you can say any of the following: 'I agree,' 'I disagree,' or 'I suspend judgement.'"
