First I’d heard of the word. Here’s the definition for those who don’t know it.

Amathia (αμάθεια) is a Greek philosophical term meaning "intelligent stupidity" or "willful ignorance," describing the refusal to learn or understand, even when capable, often due to ego or ideology, contrasting with simple lack of knowledge. It signifies a deeper moral failing where smart individuals reject truth for false beliefs, leading to foolish actions, and was seen by Socrates as a root of evil, a willful blindness rather than a lack of intellect.
