Thanks for the study. I agree on all points. This is the challenge with sociological research: it is unethical to conduct controlled studies. We will never have controlled IQ research. The study suggests we continue to perform better quality primary research, and I fully agree. Until then, as per the data in the study, the correlative evidence remains compelling. At least as far as sociological research goes.
I tend to think this research is more compelling and useful at the macro level. We should bear in mind that the correlative coefficient between IQ and income is only between 0.2 and 0.4. There are many other factors which also impact outcomes.
