I suspect your sentiment is why so many people accept confident predictions from blowhards who don't actually know/care how complicated the real world is. Maybe it's more comforting to listen to people who pretend to have the answers, but it doesn't help for making good decisions.

Personally, I think the accountability and oversight should be applied to the asshats who say exaggerated things with certainty. Yet for some reason, those people get a pass because "they were using the best information at the time" etc... It's doubly frustrating when they say, "Yeah, it wasn't so bad because you listened to me".
