There’s also people who are willfully ignorant about things that are too taxing for their mental health, such as the war in Ukraine. Some people think it’s very important that everyone knows the details on what is happening, but it might do more personal damage than good on individual who is already struggling with stress, depression, anxiety etc.
The only time when willful ignorance is bad, in my book, is
A: They’re being willfully ignorant about an essential skill that they need in order to make everyone’s day go smoother
B: They’re willfully ignorant about something but somehow still give as much of a shit about it as experts on the topic. These people are the worst.
