I don’t know about Norway, but here in Spain the % of people who sign up to the military who are immigrants has been steadily increasing these decades, so a drop in IQ does not surprise me at all.
Also, does Spain only administer IQ tests to members of the military?
Or are you saying that members of the military have a lower IQ than the rest of the population?
Do you have any reason other than Xenophobia for expecting this?
Do you have any reason to suggest all nations have the same average IQ?
It also stands to reason that there is no reason to assume Spain is at the top of the chart when it comes to national average - so they are most likely also having immigration from countries with a higher average. This would mitigate the effect of countries with a lower average, would it not?
Returning to the original point:
Because immigration usually entails an amount of merit and ability - the successful immigrants are usually at the higher end of the capability spectrum of the originating countries population.
Doesn't it stand to reason immigration would have either a minuscule or positive effect on national average IQ?

Look at a map of IQ by countries. It's not East-Asians immigrating to Spain.
The commenter should not be down voted.
Different ethnic groups have measurably different IQ's.
Ethnicity represents genes, but also a myriad of other behaviours, attitudes, perspectives: all of the 'possible differentiators' mentioned in the article could easily be accounted for simply by ethnicity. Westerners more likely to play video games, some other group more or less likely to sleep, yet another group may or not value reading or eduction. In some groups women don't play any sports, maybe the lack of activity causes differences.
Most immigrants to Spain come from poor countries with low levels of education and generally lower IQs.
Though it's a really uncomfortable bit of reality, and we don't want to provide cover for bold racism - the position that 'immigrants might be lowering (or improving, even) the IQ results' is a reasonable hypothesis on the face of it.
