In the wake of the Los Angeles riots more than 20 years ago, Congress created an anti-poverty experiment called Moving to Opportunity. It gave vouchers to help poor families move to better neighborhoods and awarded them on a random basis, so researchers could study the effects.

The program’s apparent failure has haunted social scientists and policy makers, making poverty seem all the more intractable.
