Actually, Phil, I learned about it in school, back in the days when they were teaching instead of indoctrinating.
I have 7 nieces and nephews, aged 14 to 23, so their school experience is very recent or current. They're being taught a lot, including how to learn and how to research (real research, from proper sources). Those at university, of course, have an even more developed skill in research and learning and they're working as well and gaining life experience - also through travel.
What they're being taught about learning and research is far, far better than I received. They will finish school with more knowledge and more understanding and more ability to learn than I did, as I had more than my parent, and so on.
That's not to say that various teachers don't have views on things that they take on board at various times, for better or worse, but it's far from being indoctrination. It's merely different to your experience, not wrong.
My 18 year old niece, who is taking a gap year and travelling and working, and who is a talented artist (but will be pursuing environmental studies as she is far more interested in that) and has a wonderful eye for photography, was telling me last night at her grandfather's 80th birthday dinner, that there's no art in photography. It's all mathematics. Push the button. She felt that art doesn't need maths. I asked about Escher. She pondered and we drank more wine and the discussion broadened with my wife and a nephew (16) and another nephew's girlfriend (22) about discussion versus argument and the value of honest and robust discourse.
She thinks about things. She knows how to learn. She's not an exception in that regard. Don't be like the apocryphal Charles Holland Duell, but rather like the real one, "In my opinion, all previous advances in the various lines of invention will appear totally insignificant when compared with those which the present century will witness. I almost wish that I might live my life over again to see the wonders which are at the threshold."
I think you think that your glass is half empty because the younger generations drank the other half of your drink. I think mine's half full because they've topped it up for me.
