I'm sure some areas of physics have near 100% and some simply don't.
That doesn't mean the people engaged in research at the bottom of the stack are good and the people at the top of the stack are bad. Nor does it mean we shouldn't be trying our best to understand things near the top of the stack.
Very true. But this means more statistics and controls are necessary to get solid result from a social science experiment then a particle physics experiment, no? Clearly, this is practically impossible, but there you go.
No it's not? You put more money into the studies and you can do bigger, better versions of them.
A major obstacle to putting more money into studies: people jerking themselves off about how soft sciences are a joke and hard sciences are Super Serious Business.
One example is the famous reluctance to publish negative results in psychology. Nearly all published results in (collider) particle physics are negative.
If senior faculty prefer to only hire people with a string of published postive findings, you are literally encouraging p-hacking. Again, they are not "bad" people, it is just that the system the senior people have setup in that field is not conducive to doing good science.
I am saying that we should take those claims less seriously, especially if the results from that domain don't replicate, as in the case of psychology and other social sciences.
Maybe there is little we can conclusively say about those domains.
There was little we could conclusively say about any domain until long term, concerted effort was made to understand each of them.
