ignorant

The word carries a heavy emotional weight that shifts based on the target. When describing a lack of information, it is often neutral or even sympathetic, as in being unaware of a secret. However, when applied to a person's intellect or worldview, it becomes a sharp criticism, implying a failure to learn or a willful refusal to acknowledge facts. In social contexts, it transcends simple lack of knowledge to describe a lack of social grace. In this sense, it functions as a synonym for boorishness, where the "ignorance" is not about facts, but about the rules of decent human interaction.
