In 2011, Jon Cohn wrote a story called "The Two Year Window," about new research demonstrating the importance of the first two years of a child's life. Roughly speaking, most child care that's average or better is probably OK. But down in the bottom third, conditions are often bad enough to cause permanent cognitive damage, sometimes at a biological level. One third is a lot of kids.
The caption in Mother Jones reads, "Unfortunately, this is the exception in America, not the rule." Evidently, the blonde teaching the blonde is the exception, unfortunately, not the rule.
By the way, all this talk about how there's a "two year window" right after birth to equalize IQs, which makes "Day Care, the Final Frontier," is so 2005. By 2015, I predict, the new conventional wisdom will become that the Final Frontier is Prenatal Care, providing a window exactly eight months and twenty-nine days long.
