When I said ignorance, I meant it very literally. You clearly are not at all familiar with the domain. The effort to categorize personality traits has been ongoing since the 19th century, and the big five have been studied since the 40s. Nothing about this is pop-science. This is about making measurements and predictions, which is exactly what science is. The big five have been the most useful tools for measuring personality traits for decades, and have produced predictions with far greater precision than any other framework in all of psychology, barring IQ.

I have not stated a single opinion in this thread. Everything I’ve said is supported by decades of scientific research, all you’ve posted is a long-winded description of your opinions and feelings.
