The big three of social sciences—sociology, economics and political science—have had a negligible impact in the real-time American environment and their actors. Not to be critical in the least, however rock-solid the elemental science in those schools the results are invariably fuzzy, subjective and open to widely legitimate interpretation. Political research is often a very granular art applied to micro environments for predictive behavior, while evolutionary behaviorists ignoring cultural influences cause as many problems as they seek to solve.
Economists, however, always had a titanium-solid pure empirical model right in their hands that absolutely mandated proper human behavior and response in preventing a chaotic meltdown of society (the core mission of their school and profession), the economic depression. Like all truth the model runs simple and plain.
