Repeating a point over and over, based on falsehoods, hasn't worked out very well either here or in global warming.
At some point, people notice you're lying. The conclusion might be correct, but if you get caught lying along the way, you undermine your case.
People didn't "revert." Years of this kind of oversimplification and "dealing with people like children they are" led to this ignorance. And in a rapidly-evolving situation like COVID19, this ignorance sometimes ends up biting you just months later. In my community, vaccine efficacy is well below 70%. People don't believe that since we've had months of messaging.
Yes, I do think we would have higher vaccination rates if we stopped patronizing people, and started educating them.
No time like the present to start.
