There is no such thing as social science.

I don't follow. Are there not sciences that primarily study a type of human relationship? Economics, for instance, which covers our financial relationships with each other.

Having mingled and worked at length with PhD-level folks in both STEM and the social sciences, rest assured: social scientists are some of the smartest researchers out there, almost to a frightening degree. So your dismissal is genuinely chuckle-inducing to me.
