IMO no one is born stupid, at least by the definition given in the article. One doesn't become "unwilling to change their views on a subject, no matter what" without external pressure. Just look at qanon or proud boys for example, people in distress get radicalized by finding community in the worst places. They get pushed away by friends and family as they get more radicalized. They are then trapped, unwilling/unable to change their views as it would mean being rejected by their now only community. They develop cognitive dissonance and lead generally miserable lives. You can find similar but less extreme cases in religion, politics, etc.
