what's the vertical axis? percentage difference from average test score? I mean, the chart tracks median household income (was about $60K in 2017) very closely. average income, average test scores. the correlation is interesting. not sure if the difference is small.

I could tell a lot of stories about this but the main one is probably "income and heritable ability track fairly closely" if you want an ability meritocracy this is fine if you want a gini coefficient of zero but for admission to caltech then its obviously bad

up to a point that's true. I'd really like to see this data charted at income levels between $200K/year up to $200 million/year. My hypothesis would be that above a certain wealth threshold the heritability effect breaks down sharply.

huh? if my hypothesis is supported by the data my conclusion from it would be that IQ testing is good at measuring [whatever it measures] but the tail ends of income distribution are dominated by different things than IQ
