This reminds me of "willful blindness". I find it interesting that this term was not mentioned in the article. Willful blindness started out as a legal term for refusing to know or learn something that a reasonable person would or should know. It can be used for refusing to learn that which makes us uncomfortable or presents us with a conundrum that we do not wish to deal with.
And then there are the social media which further help us avoid that which we could or should know or learn by fractionating society making it easier to find a friendly environment and avoid information that makes us uncomfortable.
