The low correlation of IQ and future wage is surprising to me given what I've seen elsewhere. For example https://www.researchgate.net/profile/Robert_Sternberg2/publication/228859220_The_predictive_value_of_IQ/links/09e4150d72ed6b102a000000.pdf https://www.researchgate.net/profile/Robert_Sternberg2/publi... finds that IQ predicts 15% of the variance in income and 25% of the variance in socioeconomic status.

Although I did look at the original study and that number comes from a linear regression of log wages and IQ percentiles. I'm not convinced that the R^2 number you get out of those two numbers really means much, the correlation is highly significant at least.
- rch 10y agoWhy do these studies primarily look at wages? Personal autonomy might be a better metric, just more difficult to quantify.
- trishume 10y agoPerhaps that study looks at wages because I specifically looked for another study that also measured IQ-wage correlation. There are studies measuring other things, I was just looking for something to compare to the study the article mentions. And I would argue that personal autonomy is just another proxy. If you're trying to measure if IQ is helpful, perhaps what you really want to look at is life satisfaction.
