fine, then what did I learn? If everything depends on the context and everything is contingent and context. Then you say fine then what did I learn if everything depend on the context and everything is contingent why come to school just go and do it. That's where I think we'll give you some clue really with maybe with what are diplomacy and principle pragmatism how that can be done although they're contingent although they're contextual. So what are diplomacy then? What is this? So scientific method, I will say then in general is subjective. So we'll talk about a little bit more closely. Policy and decision making is subjective. Whether you like it or not, that's what it is. So whether your political bias is Biden versus Trump administration, you're seeing that policymaking and decision making. So this is going to be subjective whether we like it or not. Then we're saying the scientific facts are objective and this will be maybe I think there are nuances that we don't want to get into right now. Social facts are subjective. So I'm making a sharp distinction between these two things. So there is a scientific fact and there is a social fact. When we talked about this idea of alternative fact, what people got confused is that they were mixing it up. Social facts are basically there are alternative facts. Scientific fact there is no alternative facts. If I take my temperature if you can find it to be 98.4 it is 98.4 maybe with another thermometer you can get 98.5, it cannot be 200 degrees. So that's a scientific fact. I said this is objective
