We shouldn’t merely adopt the opinions of others or be easily persuaded by arguments from authority. We should study the facts, and think for ourselves in an honest way.
We’re all wrong about a variety of things. The idea is to become less wrong, not to reach a state of comfort in our mind where we believe we’re right about everything.
This isn’t easy to do, because we’re all biased and we all have blind spots. But if we’re serious about it and we’re willing to be honest with ourselves, we can make a lot of progress.
