Anyway, just look at the reference alleles for intelligence and then the allele frequencies of each group. From the allele frequencies and their direction, it's enough to conclude that differences in intelligence will exist. I cannot comment on the impact that each difference will have on intelligence but there does seem to be significant cumulative differences when summing the pluses and minuses and their frequency.
