Been getting well into Keynesian socialist economics recently. Because the academy is basically a propaganda factory when it comes to economics, and most economists have the most bizarre and un-rigorous approach to methodology and totally lack reflexivity etc., much of that heterodox sort of stuff is available via blogs, youtube etc. Varoufakis, Ann Pettifor, Steve Keen are all really interesting. Varoufakis is particularly good cos he’s one of those intellectuals that makes everything incredibly easy to understand somehow, his stuff on a ‘new Bretton Woods’ is esp. worth seeking out (can’t be bothered to find it now).
Economics isn’t great as a social science because if you’re to engage with it meaningfully in a social way (rather than “to get a job” or “to do maths”) you have to either take parts of what some economists say on blind faith based on your political preferences, or actually devote your time (and probably academic learning) to getting to grips with the maths they do and the premises behind it. This kind of inherently limits its capacity for interdisciplinarity.
