If you try to find out whether a belief correlates with IQ and simply run a regression you sometimes get very different results when you control for whether the person comes from the US or whether you don’t control for that fact.
Correlations of very different sizes? Or just differing signs? I would not be surprised by the latter. The former would surprise me, if it applied to a randomly selected belief.
Apart from all the theoretical arguments, regression studies frequently simply don’t replicate.
The Dale-Krueger study does replicate in a sense: they got the same results for the 1989 cohort as they did for the 1976 cohort.
The US LW’ler are one average smarter, older and have higher income. If I rember right they also vote more often. But it’s been a while till a played with the data so I don’t want to say something wrong by being to detailed in my claims.

For what value of “same”? Did they first analysed 1976 and published and years later analysed 1989 and came to the same conclusions or did they just throw all data together.
