More IQ stuff; IQ among EU countries

What a coincidence;
No pointers yet, but tommorow European media will publish a science report about IQ among Europeans.
DE was best with an average of 107, NL was 2nd. UK 8th.
And -no kidding- BE was’nt mentioned.

According the researchers the climate was the main reason for the differences. And the Northern climate a benefit, and influence on brain-volume.

I wonder how one would go about finding a random sample to participate in an IQ test. Whose IQ test did they use?

Intelligence? If it came down to survival, my money is on those in the rural areas.
