Wait for the results. Then the results of the study might result in policy changes, which will then be evaluated to show how the wonderful practice plays out in the real world.
In the '90s I was all gung-ho for a policy rooted in sound research. You take families living in "persistent poverty" and relocate them. In their new digs, they receive subsidies for their living quarters. Kids attend "good" schools. The neighborhoods were middle or upper-middle class. They'd have access to good jobs. It's all the things that more recent research saying that life opportunities depend on geography, i.e., on neighborhood, would predict should work, with the added bonus that it helped break up pockets of persistent poverty. This was the prediction.
And the research said that those things did work. Kids did better in school, families stuck together better, family income rose. So the Clinton administration made it a policy to help very low SES/intergenerational-poverty families move into nice neighborhoods. This is still often the basis of mixed-neighborhoo policies in, say, Harris County (Houston, in other words).
Thing is, by the early 2000s the policy was evaluated and found to fail. Kids often returned to their original neighborhoods to be with friends. Families moved back. Even if the kids did better in schools, they were still below the "indigenous" populations. If you're #50 out of 50, it doesn't matter if your test scores are 69 or 73, you're still #50.
Except by the time the policy was shown to be pretty much a failure that did little but piss off established residents of a neighborhood and create resentment it had a constituency in the population, in academia, and in the bureaucracy. So it's still policy. Anecdotes say it's a wonderful thing; too bad there's no data to back it up--in fact, the data say it's a rather expensive wash--but in a post-Enlightenment anti-intellectual world, who needs crummy data when you have impressions and belief?
So do the study. The results will come out great. We'll try it in reality. And the results will be an expensive 0 that we're stuck with for decades, the pointless being the enemy of the good. But we'll have nice pats on the back, even if we have to dislocate our shoulders to receive them from ourselves.
