these are questions of fact, amenable to study
Well, kinda. Economics studies these kinds of things and you can see for yourself how much agreement is there about "facts" and how rigorous the papers are.
The problem is that you don't have entirely stable facts and processes like you have in physics. In social studies, technically speaking, each situation is unique and will never repeat again. Therefore a core activity for a social scientist is separating persistent features of the situation (including figuring out on which time scale are they persistent) from irrelevant and labile -- and those are usually swept into one large bin labeled "noise". This is a very non-trivial exercise given that this persistency is often conditional on some factors and that you typically can't do interventions.
So, "amenable to study", yes. "Established beyond reasonable doubt", err... I'm not going to hold my breath.
Your job, should you choose to accept it, is to comment on this thread explaining the most awesome thing you've done this month. You may be as blatantly proud of yourself as you feel. You may unabashedly consider yourself the coolest freaking person ever because of that awesome thing you're dying to tell everyone about. This is the place to do just that.
Remember, however, that this isn't any kind of progress thread. Nor is it any kind of proposal thread. This thread is solely for people to talk about the awesome things they have done. Not "will do". Not "are working on". Have already done. This is to cultivate an environment of object level productivity rather than meta-productivity methods.
So, what's the coolest thing you've done this month?
