I don't get the joke. The truth is probably that genetics do play a role (perhaps small though) in intelligence, as it does with other measures like height or bone marrow donor compatibility.
However, even the above can just be used to maintain the tinfoil conspiracy theory about jews running the world. So.... you cant get any useful conclusion with this data, even if you use the data as it is (i.e. to say "on average", and never use it to guess a certain person's intelligence based on ethnicity).
Also, the genes responsible for skin color,afaik, has nothing to do with the intelligence of that human. Otherwise, there would literally be a cap on iq for whiter or darker skinned humans. But there is not, any ethnicity can produce stupid individuals and geniuses as well.
