| I'm not sure that psychologists really even make the distinction between "what is socially learned" and what is "inherent to humans" to be honest. I want to say no one really denies traits are influenced by social factors, but I'm sure you could find some citation to the contrary somewhere. 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. |
Given these foundational issues, it's folly to try to support Big Five or any other descriptive model just by saying that it's a good fit for the numbers. Any principal component analysis will find something which factors out as if it were a correlative component. This dooms Big Five just as reliably as it dooms g-factors or Myers-Briggs or any other astrology-like navel-gazing.
(If you want an example of actual five things showing up again and again and again, mathematics has examples [3][4][5], but it turns out that when actual five things show up, then the reaction is not to serenely admire the correlation, but to admit terror before cosmic uncertainty. Psychologists do not seem to go insane and kill themselves like statistical mechanics or set theorists; have they really seen the face of god?)
