Data for that is hard to find. Since IQ is at least partially hereditary one would assume that the picture amongst legacy admissions to be at least somewhat different than other forms of social engineering. That said some people find legacy admissions unfair, but as a person that did not receive that I think it is fine because one of the purposes of any group is to provide advantage to the people in the group. The primary purpose of a long lived entity like an Ivy is to ensure the long term health of the culture that keeps it competitive, which includes providing continuity and a reason to invest for legacy families while also admitting new members from families that can provide mutual value to the entity.
