I don't think you necessarily disagree as much as not seeing your own child as the outlier they are. When you surround yourself with others who are willing to do bare minimum amounts of research to find an answer, it's easier to act like it isn't a problem.

Yet, I live in a country where massive amounts of people are rejecting things that are insanely simply to research and to prove like the efficacy of vaccines, for instance, or whether Donald Trump is a grifting buffoon. These people have no interest whatsoever in doing research that will undermine what they've already chosen to believe. Motherfucker we have flat earthers out here building rockets to "prove" the earth is flat. Even some of the ones who do research, like the flat earthers, just move the goalposts and don't seem to learn when science proves them wrong.

The sad reality is that if there are simple answers in front of them, most people won't look for harder ones. I simply think your child is an outlier in being willing to do any amount of research on things they are interested in. For many people it's incredibly hard to get them to even consider doing such a thing.
