    for such details.  However, the results echo those of a landmark study, the Abecedarian project performed at the University of North Carolina, which followed three cohorts of poor children who were randomly assigned to the treatment (early education) or control (no early education) groups.  This study also demonstrated the strong effects of early education, again lasting well into adulthood.

      And that's what I was referring to. I should have specified. Obviously I don't expect the kos summary to have the full rundown on confounders.

      In this study, students were not randomly assigned. It was suggested that since the control group participated in another enrichment program they shared the subtle family motivational traits that tend to bias studies like this without random assignment. It'll have to do, but it was kind of weak.

      The other study sounds stronger.

      indicates they have published follow-up up to age 21. The list of gaps indicated in the intro to the new Science paper seems aimed at aspects of the Abecedarian results. However, the Abecedarian may be more compelling because random assignment is so crucial.
      If you take Abecedarian as showing the basic phenomena more reliably, and the current Science paper more as sorting out sub-categories and extending the time period, then the combination is pretty good.
