If there's one thing in this world we need, it's to give even more data to the people who have no idea how to interpret data.
I guess we can't stop science. Instead we gotta educate stupid people, which might be harder. Undecided.
EDIT: To clarify, I highly doubt this will yield much useful information. I think intelligence is more down to environmental factors than people like to think. All this really hopes to achieve is give a basic idea of how smart someone could turn out to be. And even then it's unclear just how reliable that ballpark is. So the main outcome would be the recourses of people who absolutely cannot be trusted to see any actual data. They'll just end up making a whole ton of kids grow up feeling like shit and performing like shit.
