> Even if all the statistical, p-hacking, publication bias, etc. issues were fixed, we'd still be left with a ton of ad-hoc hypotheses based, at best, on (WEIRD) folk intuitions. This is the quiet part which most social scientists, particularly psychologists, don't want to discuss or admit: WEIRD [0] selection bias massively distorts which effects are inherent to humans and which are socially learned. You'll hear people today crowing about how Big Five [1] is globally reproducible, but never explaining why, and never questioning whether personality traits are shaped by society; it's hard not to look at them as we look today at Freudians and Jungians, arrogantly wrong about how people think.

The Big Five are pretty reproducible in part or in whole, but it's strawman to say psychologists are "never questioning whether personality traits are shaped by society." That's not just not true, nor is it even clear what that question means. Go to Google Scholar and search for "Big Five" and terms like "measurement invariance" or "cultural" or "social" or "societies" and take a look.
The Big Five are meant to be descriptive, the "why" is a different issue. (Just to explain it a different way, let's say you do unsupervised learning of cat images, and find over and over and over and over and over again over decades and different databases that the algorithms always return the same 5 types of cats, plus or minus a little. Wouldn't you make a note of it if you were interested in visual types of cats?) And it's important to remember that some consensus around the Big Five wasn't really until the 90s (even today I'm not even sure there's "consensus" around the Big Five).
I agree that there's a problem with selection of participants, but the only way to do that is to increase participation of the scientific community worldwide. And there are whole fields (cultural psychology) dedicated to the problems surrounding this issue.
The Freudian comparison is also worth commenting on in two respects: first, Freudians got in trouble for not pursuing falsifiable empirical research, which is simply not the case for the things you're talking about. Second, everyone loves to hate on Freud, but the basic tenets of unconscious versus conscious processes that sometimes conflict are still a bedrock of neurobehavioral research, including two-system theories ("fast and slow"), which won someone a Nobel prize and is a darling of cognitive researchers. There are legitimate discussions to be have about the utility of two-system theories but those discussions are far more sophisticated than the criticisms I think you're referring to.
