My parents were both vaccine skeptics. Covid, and all of public consciousness and education about vaccines, convinced them both that vaccines are important. Contrary to common thinking about vaccine skeptics, they are both highly educated successful people and when presented with solid evidence that their beliefs were moronic, they changed their thinking. It’s not helpful to be so cynical, because people do change. I see people change their minds about things all of the time. Sometimes for the better and sometimes worse, it’s information warfare. As long as we remain cynical and unmotivated, the morons win.
