First, the original point was "as IQ goes up, so does average income."
...
And the main point is that average IQ is higher and so are average wages.
The original post that started this line of discussion was this:
Interesting and unsurprising, though giftedness doesn't imply high SES, or vice-versa, though.
Statistically, it does. On average, intelligent people are more productive, earn more, and have smarter children.
So yes, you are correct on your main point. But... context. This was said in direct response to a comment about the correlation of SES and
giftedness. So while yes, I agree that higher average intelligence equates to higher average income, the point is we're talking about outliers here... and a group that is poorly studied, IMO.
From your example, for instance:
But I was right about the summary article having cheated: true, ("uncorrected") accumulated wealth in the IQ 105 group was ~$84K compared to ~$71K in the IQ 110 group. BUT, wealth jumped to $95K in the IQ 115 group and $133K in the IQ 125+ group.
The highest IQ group represented here is 125 and up, but most people put the threshold for gifted at 130 (assuming 15 SD scale), and the range for "optimal intelligence" at around 120-145 on the same scale. These numbers would mostly represent the optimal intelligence group, including many members below what we would term "gifted." So these numbers aren't really useful for our purposes.
For illustration purposes, 125 IQ occurs 1 time in 17, and 130 occurs 1 time in 33. Statistically, then, this suggests that nearly half of the group would not be considered gifted under the standard 130+ definition of the term.
