Oof. You just trampled one of my pet peeves: Social Science is a subset of the Sciences, not the Humanities.

There's still a persistent anti-positivist streak in the Humanities in the US, but mostly positivism has just been irrelevant to the work of Humanities scholars (though this is changing in some interesting and exciting ways).

More importantly, the social sciences in the US are overwhelming positivist, even amongst researchers whose work is not strictly empirical. I wish I could take credit for those good influences, but I think you're probably the one deserving of kudos for managing to become a rationalist in such a hostile environment.
