I think they control for this by saying inter-family variation explains almost the entire effect. So that suggests the problem is something with the Norwegian environment (and possibly the rest of the developed world) rather than the relatively poor environment that many immigrants and refugees come from.

I can't access the full study, somehow it's not published yet for me. But it doesn't appear like migration played a role.

Correct. Was pretty obvious during my stays in Scandinavia that the people trying to sell me drugs and fighting in the train stations were not locals. Not that those actions in any way would be a correlate of IQ /PC logic.
Also, Norway has been a popular country for migrants for decades. If you come from a less developed country where, for instance, the quality of food and health care (factors relevant to IQ) aren't as good as in Norway then this surely influenced the IQ of your predecessors and hence you. If the share of such migrants is big enough to influence the average (I don't know!) then this could be an explanation.
