Social science research is very important. It's also very hard to do. There are also fads in the social sciences, unfortunately, and when fads get identified, there's an unwillingness to continue funding in that kind of area, so cash funding starts to seep away.
I have seen in my academic lifetime a considerable number of movements, some of which have been remarkably successful and remarkably profitable, while some have withered, even after quite a lot of money was invested into them.
That is something I think one has to come to terms with in research. Not everything is going to succeed. Scientists...social scientists will not always know what the profitable directions are. It's natural to be disappointed when money is invested and nothing comes out of it, but I think you have to look at the large picture.
