The only time I don't care to "educate" myself is if I don't think it has a huge impact on the overall big picture.
Like someone was arguing with me the other day about having allergies from being around animals. About 60 seconds into the argument, I was basically "over it". I don't want to spend time arguing about it, because I don't really care. It doesn't really affect my quality of life or anything (plus I was busy at the moment), so I'm not going to argue with you over it. And maybe that person thought I was "content to remain ignorant" about the subject.
If it's an "important issue" that makes a difference in the day-to-day, then Ti isn't going to "remain ignorant". Ti is going to learn about it until it understands it fully. In fact, I would even argue that Ti will "over-educate" itself.
