Perhaps 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.
