The good news is that we know some adjustments to make to education that would reduce that number. For example:
> More children taking MVM [multivitamin with mineral] supplements (44) than placebo (25) showed increases in nonverbal IQ scores of 15 or more points (35% compared with 21%; P<.01). The authors speculate that this result may be attributable to the fact that one in 7 schoolchildren was undernourished.[0]
The bad news is we won't do it. Implementing effective policy is the hard part.[1]
