What is the difference between "social science" and "hard science?"

Isn't all science the same or am I missing something?

Science is a method, but social science deals with dynamic units of observation. You can reliably repeat a chemistry or physics experiment, because the behaviours of the fundamental units do not change over time. Social scientists study people, and people change. We still use the scientific method, but it's more of a framework to deal with bias and the challenges of causal inference than in the hard sciences. Hence few "iron laws" of social science.
