While you're at it, how good is capitalism as a moral system?
What in the bloody Hades do your threaf topic have to do with your OP???!!!
Natural sciences have nothing to do with religions and nothing to do with capitalism.
Capitalism have to do with with government policy over commerce and trading, and ownership of businesses, which outothe realm of natural sciences.
I am not a "Social Science" person (eg psychology, sociology, anthropology, etc), but capitalism may be covered in Political Science and Economics, which are Social Science disciplines.
Social Sciences differ from Natural Sciences.
Natural Sciences cover areas in physics, chemistry, Earth science, astronomy & life sciences (anything relating to biology).
Social Sciences, OTOH, concern with everything relating to humans behaviours, human cultures & human activities.
Social Sciences include psychology, behaviour science, sociology, anthropology, archaeology, human demographics, political science, economics, laws and legislation, etc. There are lot more, but these are the common branches of Social Sciences that I can think of at the top of my head.
While human biology, like study of human brain would fall under biology, hence it belong inside Natural Sciences, but how humans think and behave is outside the scopes of Natural Sciences.
So capitalism isn't cover in Natural Sciences.
In social sciences, falsifiability and scientific method aren't very important
As to religion, they have nothing to do with Natural Sciences.
Religions generally fall under the study within Humanities, like arts, literature, music, history, etc, but religions may also be considered cultural endeavors, so religions may be cover as parts of anthropology and sociology, which are study of human cultures and social activities
But religions and natural sciences have nothing with each other.
