The free-for-all element that there are always variables that cant be accounted for. There is more that you dont know in each so it becomes a science of predictions. I would predict that in our lifetime the phrase 'social science' will become extinct. I have spent the last 15 years, up until 2 years ago, thinking about said subject, and the whole thing feels like a fairly decent summer camp experience. ie, no real resolution, and you always want more, and you didnt learn anything while you were there. It is more obscure than philosphy.
