I’d argue not, you can’t have reproducible experiments with control groups. You can’t really follow the scientific method with economics and politics.
Can’t fault you for consistency. Whether or not the soft or social sciences actually are “science” has been a conversation for a long ass time so I won’t argue lol.
I will say though, that Marxism is the closest I have seen to a proper scientific theory of political economy and I study a natural science (physics) so I think that counts for something.
