Do you think soft sciences are sciences in the same mode as physics and chemistry?
Well, they’re not. Soft sciences have value judgments in them. They deal with human behavior in its social and cultural aspects. Examples of soft sciences are psychology, sociology, economics, and politics.
Hard sciences strive to understand the physical world and its phenomena. It uses observations that can be measured, shared, and verified by other researchers.
So what? Good question. Public policy debates often have recourse to theories in the social sciences. We mustn’t forget – social science theories already contain value judgments.
