I agree that celebrating ignorance is the problem.

I work in tech and the number of people who outright refuse to even listen to a very high level technical explanation, or follow instructions poorly with the excuse that they "don't know tech" is very high IMO. I can usually see when people disconnect from a very very basic discussion about an issue. If it's more complicated than "I'm working on it" then they don't want to hear it.

I usually refer to this as "willful ignorance", aka, people who are otherwise smart, and capable of learning, who actively put in the effort to not learn anything new. Usually, willful ignorance is more effort than simply listening and trying to understand.

A lot of the people you're referring to seem to not only be willfully ignorant themselves, but also desire to celebrate people who are willfully ignorant and celebrate people who are blatantly ignorant.

Don't get me wrong, I have nothing against anyone who doesn't know something, or people who don't want or need all the details; I certainly don't have anything against persons that don't have the ability to understand. But if you can't even entertain the summary of something, you're the problem.

You can lead a horse to water, but you can't make it think.
