I'd go even further: even the ‘cognitive elite’ (the university educated? researchers?) understand only a thin spike of frontier human knowledge, even if they might understand it very deeply. Outside their specialty and maybe a slightly raised background level of general education, the world is still magic. No one human understands even a significant chunk of human frontier knowledge. That's why we build artificial societies comprising many humans to make complex decisions.
