Seeing that countries vary wildly in how much they contribute to the EU, and vary somewhat in g in Europe, it seems worth checking if it there was a correlation.
The EU reports every year how much every EU member contributed (positive or negative). The latest numbers are from 2012, which can be found here (danish): http://www.eu-oplysningen.dk/spsv/off/alle/117_90/

There is a correlation of -.3, but its not significant in MR. The effect of east block is, however, very large.
The correlation of -.3 is reduced due to restriction of range. However, it seems that no one has actually calculated the entire global deviation for IQ, so I cant use formulas to correct for restriction. (see here: http://www.uk.sagepub.com/salkind2study/articles/10Article01.pdf)
Basically, what correcting for restriction wud give us, is the correlation between LV’s national IQ’s and EU net contribution IF every country in the world was in the EU.
