Ignorance vs. Stupidity vs. Naivety

This is the distinction that matters most, so here it is plainly.

Word	Meaning	Can it be fixed?
Ignorance	not knowing the facts	yes, by learning
Stupidity	poor judgment with the facts	harder; it is a habit of mind
Naivety	trusting too easily from inexperience	yes, by experience

Calling someone ignorant says they lack information; calling them stupid judges their mind. The first can be cured with a book, which is why writers should keep them apart. It is the same precision our guide to another word for entertainment practices with tone.
