This conflates social science with the humanities. I agree with respect to the humanities. Less so with respect to social science. People in large groups do in general follow certain trends and we do have decent ways of establishing causation. Now there is a lot of stuff that people do that we can't analyze quantitatively due to lack of data or other blockers. For these qualitative methods will have to do. Fine, but then we should accept that the conclusions from qualitative analysis are less firm and judge them accordingly.
