I once did a comic review on why one can never esteem oneself wrong. The reason being that when you know you were wrong, you are again right. This video is interesting.
The proposition here is that stupid people have a tendency to think themselves correct and smart people have a tendency to doubt. The stupid person, therefore, is too stupid to see themselves as wrong and the smart person is too doubtful to take a position.
Now, this subject interests me in exploration of how I may keep my own perceptions safe whilst taking into account the opinions of others.
