Is there a rule or a thing in philosophy that names the philosophical state of believing in something and acting/following those beliefs, (simply because they were taught to you in school, by your friends, and/or by your family), (perhaps most people around you still believing in this thing), automatically sometimes even if your personal views are against it and even when large amounts of evidence are against it or pile up against it?
