Those examples are political because they're indirectly about controlling groups of people. But not everything is. Sometimes it's personal pride - you might make a mistake on some inconsequential fact then double down after you realize you're wrong just to feel like you're right. People do that. Or you might just have learnt a wrong fact by accident and repeated it. If it requires intent to mislead, then the classic activity of bullshitting (did you know a mole can smell a dead cat from one mile away?) would be spreading misinformation, but we don't call it that.
