For one thing, nobody knows what to do, pragmatically, about complexity.
Secondly, you can’t teach non-linearity to people who know nothing about math, systems theory, linearity, probability, calculus, etc.
Despite claims of “scientific management” and “taylorism”, the scientific approach never made it to the hearts and minds of managers. Less than 5 percent of them have been trained scientifically. The vast majority merely go through a technical and professional education: accounting, marketing, vanilla statistics, “strategy”, etc.
Teach them scientific methods and approaches. Teach them how to be rigorous; how to be open-minded; how to be inquisitive; how to be curious; how to communicate unambiguously. (N.B.: the latter requisite calls for language mastery in addition to logic).
And also teach them the grand metaphors that Art has been creating ever since the advent of homo sapiens. Through art, literaure, music, we find out as much about humanity, and the real world, as with science itself -if not more.
(This does not mean running those horrifying seminars where CEO’s are thought how to use Art in Management: it means that, when they are young, to-be managers should be thought literature, art, music, etc.)
