Scientists have long thought that the bizarre and fantastic world of non-locality, indeterminacy, and wave/particle duality that physicists discovered in the early 20th century was confined, for all practical purposes, to the sub-atomic level. At the macroscopic, human level it’s been assumed that our familiar classical, Newtonian physics still rules, a belief duly reflected in the fundamental and almost entirely unquestioned categories of social scientific thought today: classical logic, classical probability theory, classical decision and game theory, and so on, rather than their axiomatically completely different quantum counterparts.
