I've tracked down several popular quotes attributed to influential figures. All of them false.
And when you tell the people who are spreading them, they're just not interested. It's much more fun to believe Einstein agreed with you. Or that he was bad at maths, just like you. Or that he played electric guitar like a dude.
And, a few people will double-down. Just because you can't find a source, doesn't mean he didn't say it. Or think it. Or tell it to me in a dream.
For those of us who care about accuracy, we struggle with the knowledge that a lie is half-way around the world before the truth has put its boots on. Well, that's what Mark Twain thought anyway.
