According to The Economist, 4/2/2009, "Neuroscience and social deprivation: I am just a poor boy though my story's seldom told":
THAT the children of the poor underachieve in later life, and thus remain poor themselves, is one of the enduring problems of society. Sociologists have studied and described it. Socialists have tried to abolish it by dictatorship and central planning. Liberals have preferred democracy and opportunity. But nobody has truly understood what causes it. Until, perhaps, now.
The crucial breakthrough was made three years ago, when Martha Farah of the University of Pennsylvania showed that the working memories of children who have been raised in poverty have smaller capacities than those of middle-class children. [emphasis added]
OK, keep that bold-faced statement in mind. Now let me offer you a bet. Suppose we have a large group of "children who have been raised in poverty", and another large group of "middle-class children", taken from the same groups described in the cited research; and we measure the capacity of their working memories, using the same testing techniques as the cited research. We pick one of the "children raised in poverty" at random, and one of the "middle-class children" at random. Will you bet me that the rich kid will outscore the poor kid, giving odds of, oh, say, 2-to-1? (That is, you put up \$200 and I put up \$100.)
You might not like to gamble on single events — I certainly don't — so let's give you the benefit of the law of large numbers. We'll run this same bet 100 times, with 100 different random pairs of kids. Will you take the challenge now?
