Ignorance, however, has more to do with not paying attention to something which could be paid attention
to...its root word is ignore. To ignore something has little to do with the ability to understand it. Therefore, the opposite of ignorance isn't intelligence...its
awareness.
Lack of or diminished awareness can have its roots in just not knowing about it, being trained/conditioned to not pay attention, or simply the lack of desire to know. Whatever the source...the result is the same, ignorance (even though ability may be present or may be developed). One can never understand something that one ignores. Awareness can lead to understanding...in fact, it is its prerequisite...but without any guarantees.
