23: Please stop citing that Swedish study purporting to show that IQ stops mattering after the 90th percentile or whatever! Emil Kierkegaard has a summary explaining the possible statistical missteps, and Cremieux has more information here and (buried in the middle) here.

Class was more complicated7. The Swedish study said in the abstract that it found women tended to marry down in terms of class, but I had trouble finding that effect in the data, and it looked pretty small if it existed. The Norwegian study said they tended to marry up, but with the same caveat. The two American and one English study were explicit about very close class matching, sometimes implausibly close.
