No. I mean, yes. Wait, no… I mean, maybe?
I feel most people confuse ignorance with stupidity. Just because you are ignorant about something, doesn’t mean you’re stupid. In fact, there are many upon many things we are all ignorant about, but that’s ok because we don’t need to know everything, nor do we have the time to try.
Stupidity is lacking the comprehension about something you already know or have been told about. Jumping off a cliff, not fully understanding the nature of gravity and mortality, is ignorance; jumping off a cliff, fully understanding the nature of gravity and mortality, is stupidity. The people who think they know everything, are ignorant, but if they know they can’t know everything but still think they know everything, then they’re stupid.
