My recollection from Freakonomics is they found that the children who lose the lottery still do as well as those who get in. The differentiating factor seems to be parents who care enough to enter the lottery in the first place.

Their research was based on magnet schools in Chicago in the nineties. I don't know how well that model correlates with Success Academy.

I don't believe that applies in the Chicago study because they just looked at data retrospectively. There were no observers when the events were taking place.
