There are plenty of high IQ individuals out there who will never have a high income--or do they not count? They didn't use it.
If a talent isn't applied nor developed, it doesn't mean squat. That is my point.
ALL other things being equal, your numbers will work out every time. Otherwise, you don't have a valid experiment.
But all other things are not always equal, and thus, you will find among those ranks people who applied what they had to work with and did better than those who may have had a higher IQ.
I will not even attempt to explain statistical analysis to you. Suffice it to note while the average male is statistically significantly taller than the average female, that does not appropriately imply that every male is taller than every female. Don't let the trees blind you from seeing the forest. Good bye.
