The very objective of social science research is not to discover abstract and universal laws but to understand population heterogeneity. Due to population heterogeneity, causal inference with observational data in social science is impossible without strong assumptions.

Web$\begingroup$ +1 for the sensible discussion; a few points though. Inferential machinery is unavailable for population analysis, but in many modeling cases, I'd question whether one ever has the population data to begin with -- often, it's not very hard to poke holes.
