No test measures intelligence. A test only measures you relative to the persons that wrote the test. – loosely quoting Asimov.
2007 is ancient history now. It is an interesting graph that one might correlate with a lack of meritocratic structure in society, but I’m on the low end cause I say this without looking up and reading the study. Pretty pictures evoke emotional blabbering bias and all that.
I do not think that would be as correlated as you imagine either. Conservativism is not particularly intelligent. Spotting an opportunity will often evolve and lead down different paths. Many engineers have gained and lost vast quantities of wealth pursuing ventures. Business is hard and it is impossible to constrain all variables.
Fair, there probably isn’t any correlation, I’d just like to believe that I’m smart because I’m good at saving 😆 Although my last IQ test (during my Adhd evaluation last year) wasn’t much over 110 anyways, so I don’t even count as smart on paper haha
There might not be any single correlation, but if it were possible to measure “productive output” in some normalized manner over a career, there would decidedly be a correlation I imagine
