I wanted to stage that question, and also propose my own answer. I think there are a few reasons why most people are oblivious:
1) We start out as a blank slate and need to be given wisdom
- When we're born we literally know nothing, and need to be educated on how the world works. Given that the vast majority of education systems in the world aren't that great, and higher education almost always has massive entry barriers, most people are simply not exposed to wisdom, and so don't have the wisdom to.. well.. seek out more wisdom
2) The world is incredibly complex, and difficult to understand
- Have you ever tried to understand economics? It seems that a lot of economists barely understand economics. And that's just one field amongst a plethora of other fields, all with a huge number of sub-disciplines. Even if you were to dedicate all of the time you had in your life where you weren't just eating, sleeping, exercising, and going to the bathroom, to learning about a field, it might take you multiple years before you gain any type of wisdom about that field, and then you have hundreds of other disciplines left to learn
3) Many people have weak logical skills
- Not only is the world almost limitlessly complex, a vast majority of people don't seem to have the brain power necessary to map out greater frameworks about the world out of the plethora of facts that come at them. They're all smart enough to thrive, sure, but getting beyond knowing how to type, fill up a car with gas, and budget in groceries is a very slow process.
4) Caring about knowledge isn't 'normal'
- All over media we see images of sex, alcohol, whatever, but rarely do we see a nerdy guy with glasses reading a book. I don't know about anyone else, but when I was growing up I don't recall a lot of people I knew telling me they were just going to 'stay in and read' over the weekend. Everyone would have given them a pretty weird look.
5) Our ego usually takes a stance against criticism
- Ever tried to give someone advice? Sometimes it works, usually you find yourself in a defensive argument as whoever you're talking to tries to save face. What could have been a great learning moment and transfer of knowledge, becomes another person still being shrouded in darkness.
Those are a few barriers that I can think of. Is there anything else to add?
