I think this is not as simple as simply askes. Einstein said: "All knowledge flows from experience." And historically too the phenamena of "Cultural diffusion" from high gradient to lower ones is evident. Birth of civilizations in history had knowledge driven; both immaterial knowledge (intellectual & scientific etc) and material knowledge (methods & techniques of doing things). This flow of knowledge from then developed world to then developing is marked centuries of landscape mostly through armed expeditions. Greek, Roman & Islamic knowledge & technologies dissemination sprawled. Now we have knowledge management platforms, but the phenamena perhaps a natural law of social sciences continue to manifest itself. But now complexities have created need of contextualized generation of idiginous knowledge through integrated benchmark system.
