I share some of your sentiments for the softer social sciences. I've also grown increasingly skeptical of significant portions of economics as well. Another author I've recently learned of, still need to start chewing into his work, is Jonathan Nitzan, whose Capital as Power is predicated on the notion that splitting Economics and Political Science apart was a mistake. I'd been leaning that way myself.

Lawrence Lessig's Free Culture notes that much recent copyright wrangling is really a return to feudalism. I've been suspecting that it's rather more than just copyright.
