I’d like to have a deep understanding of a few things, a pretty good understanding of more things, a passing knowledge of a lot of things, and think it’s impossible to know a whole lot about a whole lot of things.

I think it’s fine to say you have not the means to evaluate the sources of “information” available to you, if it’s not something immediately necessary to you. As I said to someone else, your time and attention are not unlimited resources. Better to use them on things that matter to you.
