Slightly unrelated tirade:

Background in psychology here: Psychology and sociology are also terrifyingly hard fields to pin down. Any one human's behavior can be wildly inconsistent within a given set of parameters, and ppl evolve across time. Cultural context and social expectations come into play at and individual level.

Add in individual sensitivities to authority, understanding of a request, general intelligence, and you get massively varied outcomes that may change as a person grows and changes.

Then, for sociology, pile on group pressures and tendencies, plus group think and group cultural context (I have no background in sociology).

I truly believe psychology and sociology are great fields of study, that yield light on human truths. That said, from a technical scientific perspective, I think it's nigh impossible to measure their value the same way as you would for mathematics or physics. At least, without finding a way to apply those fields to psychology lol
