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’d like to see the same chart done but with EQ (emotional intelligence).
I’d also like to see the chart if it was actually representative of the rich. Populate the chart with individuals reporting >2.5 million in income per year.
This is more like a chart of, “does being smart help you stay above the poverty line?”
Same and to include genius IQ
Actually it should show net wealth, not income, as the truly wealthy avoid income tax by taking out loans on their (appreciating) assets. The loans have a very low interest rate, much lower than their assets appreciate, so they are always ahead and can pay off the loans with more loans. The wealthiest people don’t really have jobs or need jobs for income, they use jobs for power and manipulation.
