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.
For this research it doesn’t matter how much wealth they control if it’s not even a suburb sized group of people globally who are billionaires, median income for ethical vs inethical groups would probably not move any statistically significant amount
I think you’re missing the point.
I know you want to complain about unethical billionaires but the point here is about looking for a trend between ethics and income, not prevalence of unethical behaviour amongst billionaires
No the trend was about unethical behavior and billionaires, not income. And that trend is close to 100%.
