You are not right to say something like this.
If you want to compare people, they must have the same basis, it means the same life, education, experience etc.
If not, it's natural that person who is more educate, experienced etc. will have better results in any research about such subject.
If you replace white and black child, and white child send to Africa, and black to America, who will be smarter than?
What do you think?

Daniel, what can you say about
birth control for black people in Israel? I think it's a terrible crime! It is worse than Holocaust! This is beyond racism. Genocide. Pure fascism.
Israel needs to be more tolerant and
fight racism; break the wall and let the respected asylum seekers in. Refugees welcome! I wish your children playing with black migrant children.
