Today, more than one in five American children live in poverty. How, if at all, to intervene is almost invariably a politically fraught question. Scientists interested in the link between poverty and mental health, however, often face a more fundamental problem: a relative dearth of experiments that test and compare potential interventions.

So when, in 1996, the Eastern Band of Cherokee Indians in North Carolina’s Great Smoky Mountains opened a casino, Jane Costello, an epidemiologist at Duke University Medical School, saw an opportunity. The tribe elected to distribute a proportion of the profits equally among its 8,000 members. Professor Costello wondered whether the extra money would change psychiatric outcomes among poor Cherokee families. …

Roughly one-fifth of the rural non-Indians in her study lived in poverty, compared with more than half of the Cherokee. By 2001, when casino profits amounted to $6,000 per person yearly, the number of Cherokee living below the poverty line had declined by half.

The poorest children tended to have the greatest risk of psychiatric disorders, including emotional and behavioral problems. But just four years after the supplements began, Professor Costello observed marked improvements among those who moved out of poverty. The frequency of behavioral problems declined by 40 percent, nearly reaching the risk of children who had never been poor. Already well-off Cherokee children, on the other hand, showed no improvement. The supplements seemed to benefit the poorest children most dramatically. …
