I'm talking about willful ignorance. as in, where a person KNOWS they can be smarter, or has a way to learn about something useful etc, but is too lazy etc to do it. i guess this could go into the whole "is laziness a sin" but let's not.
so let me restate my question. Is deliberate stupidity a sin?
I think willful ignorance is immoral, in part because it has the potential to impact others in negative ways.
