We live in a golden age for autodidacts, that people often seem intellectually incurious says less about the society and more the people who constitute it, many people are simply incurious - it’s not a bad thing, it is their life and they are free to live it how they want, it doesn’t hurt me that people binge watch the Kardashians.
And the idea that society has somehow gotten worse and prior generations where not like this is crazier still.. we are only a couple of centuries out from executing spinsters for witchcraft and believing in curses.

I've always strived (but not always achieved) to reach my opinions on the world based on evidence and figures and facts that I've looked at myself deferring to experts in the various fields where I'm not educated enough to understand (medicine - I trust my doctors).

Maybe we live in a time of unprecedented access to education and affordable materials, which is also a time of extreme inequality and selective enforcement that grinds most people into the dust.
