Sometimes we’re wrong. Sometimes we’re spectacularly wrong. This is the human condition. There’s nothing to do about it but cultivate humility, apologize when appropriate, and have the good grace to treat people others as you would have them treat you when you’re embarrassingly mistaken. I don’t think there’s another way to engage in political discussion politics outside a partisan echo chamber without becoming cripplingly bitter.
There is one thing we can avoid. We can avoid trying to trick people when we know we’re wrong. It seems fundamentally indecent for smart people who understand data to nevertheless manipulate it in a way to advance a narrative that they know isn’t true.
