I've said this before but I want to say it again: I think PGS projects that screen for intelligence/EA are genius products. They promise a margin-of-error level improvement on performance that can be fully evaluated only at the time the grown child applies for college, and the products are going to be purchased only by parents who were already going to fold space like a Guild Navigator to ensure their kids get into selective universities, so the vendors win "either way".
As an aside, I would be a lot less irritated with college admissions scandals like we saw a few years back if Lori Loughlin had to transform herself into a floating tank monster to pull it off.
