I would argue that an individual (and in turn, the entire world) would be benefit more from learning the "languages" of, or getting a good grounding in, logic and epistemology.
Logic, so you can think straight, and epistemology, so you are able to recognize when your axioms are not actually hard facts, which is where a lot of complicated fuzzy-logic style disagreements (anything related to complex systems (weather, economics, government), culture, gender, sexuality, etc) break down even between two people who have highly advanced logical capabilities.
