128 sats \ 6 replies \ @kepford 13h \ parent \ on: SAT score distribution by parent income charts_and_numbers
Do you hold much stock in SAT scores? Or IQ for that matter?
SATs matter to most high wealth people so it would make sense that their kids would get more help even if they are not naturally of higher intelligence.

My recollection is that SAT tutoring is only worth a few points which wouldn’t even register on this chart.
The best predictor of income is IQ and IQ is heritable.

Yes, its not "the sole predictor", but of the different variables its the best single variable to choose (if you must choose just one variable).

Really? I assume on average of W2 wage earners?

Not specifically. If you give a bunch of kids IQ tests, those results will predict their future earnings better than the other stuff you know about them.
It's still a noisy predictor, though.

Not particularly. They certainly don't correlate to "goodness" or "ethical" (IQ is maybe even inverse correlated).
I may have been wrong to say "strongly correlated" but they (IQ and Income) are definitely correlated.
Recent research from Sweden has uncovered a fascinating pattern: the relationship between cognitive ability and earnings plateaus and even reverses at the highest income levels. This finding challenges the assumption that top earners achieved their positions primarily through superior intelligence.​
Using data from 59,000 Swedish men who took mandatory military conscription cognitive tests, researchers found that while cognitive ability strongly correlated with income across most of the distribution (correlation of 0.40), this relationship fundamentally changed at high income levels. Above approximately €60,000 annual salary (SEK 600,000), average cognitive ability plateaus at a modest level of about +1 standard deviation (IQ ~115)
From just a pedestrian view....IQ is mainly a pattern recognition test...wouldn't you expect people better at pattern recognition to figure out ways to earn income at a higher incident than those poor at seeing patterns?
