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.
Pretty well backs up the a statement I’ve been making for years. You don’t have to be smart to be rich. You just have to lack decency.
Rich people aren’t even in the graphic, they’re way off the top of the scale. The top of this graph doesn’t even get you into the top 5% in my state.
Being smart might help you get a better job, but jobs aren’t a great way to become rich anyway.
