[LudwigNagasena]

Economics is not really something people think of when they talk about humanities or social sciences.

Indeed, in Econ grad school I learned a lot about control theory, statistics, dynamic programming, etc. But I was never told to read Foucault, Levi-Strauss or even Marx - something that sociologists and other people in humanities usually have at least a basic understanding of.

If we judge what is science by level of quantitative rig our then economics is the only social science.

There are definitely areas of overlap with social sciences--especially these days. Behavioral economics (for which Richard Thaler won a Nobel Prize a couple years back) grew directly out of behavioral psychology for example.
