I think the authors are thoroughly confused. The presence of assortative mating in no way reduces the potential narrow-sense heritability of a trait.

  I think you are thoroughly confused. They are not saying assortative mating changes heritability, they are saying assortative mating is messing with our techniques to estimate heritability, and so the true number is less than we thought, while still stable. We need better statistical techniques to infer heritability in the face of this problem.

    was just writing this. assortative mating certainly doesn't change the genetics, just the care with which estimation of the genetics must be done.

      Of course it changes the genetics. In fact it's expected with traits like this. Observing it doesn't make estimating the narrow-sense heritability any harder (or easier).

    Yes, that's what they're saying. It's not true.

      Do you have an article for that, or are you saying that out of your own expertise?

      rich people tend to live longer (completely irrespective of genetics), rich people marry rich people. In case you didn't understand what the article was trying to say.
