"You know, I also keep watching them talk about how smart they are, and keep thinking about how actual smart people don’t tend to do that.
Like, listen to Neil DeGrasse Tyson deliver a lecture, and see how often he’ll talk about how smart he is. It’s not going to happen.
You know the type of people who do like talking about how smart they are? ..."
If anything, the more you know, the more you feel like you don't know anything and try to keep quiet about your supposed ignorance. It's always surprising to talk to someone about something you feel like you don't know a thing about, and then suddenly realize that your knowledge about some topic far exceeds that of the average person's knowledge on said topic.
That's true high intelligence in my opinion; knowing that you know nothing.
And it makes a lot of sense too. Because in the end, the world is so complex that there is really no end to what we can learn about it.
Imagine for a moment that a subject that you are learning about is an endless mansion. When you start learning, you are in a room with four doors on each side. You don't know anything outside of that.
If you stay there, you might feel pretty knowledgeable, like you know a lot about this mansion based on one room that you are in.
But let's say that you can curious...
You want to know what is behind one of those doors, so you open it up. And what you find is another room with more doors. You have answered one question and discovered a new room. But now you have three more unanswered questions.
You have gone from having four unopened doors to having six.
So you open another door and see what's inside that. And again, you are met with another room just like the others.
The further you go into this mansion, the more unopened doors you realize there are and the more you realize how little you actually know about it.
Somebody who never ventures outside of that first room will feel pretty knowledgeable about the mansion.
This person only has four unanswered questions.
But the person who explores hundreds of rooms is one who will have hundreds of unanswered questions.
Therefore the most confident person in their knowledge will paradoxically be the one who knows the least.
