Many are saying that this decline is obviously due to immigration & higher fertility of lower IQ. I defer on my local expert

"the issue is not that educated Norwegians are increasingly outnumbered by lower-IQ immigrants or the children of less-educated citizens."

That Norwegian study is the odd one out. Unfortunately, no one else can really verify the methods or results because it's based on secret register data. I don't really understand their methods , so I don't trust it.

No, these are register data. Very tightly controlled, straight from government files. Only approved professors & underlings can get access to anonymized data.

Only Norwegian professors can apply. After that, there's a lot of red tape. I don't know details, I'm just assuming it works the same way as it does in Denmark because that's the case 95% of the time.
