This piece at Marginal Revolution draws our attention once again to the ways in which being rich benefits the rich twice–once in terms of a direct access to wealth, and once in terms of how it allows the wealthy to preserve cognitive resources that allow them to make decisions that benefit their long-term self-interest.
Thus, SMS [the researchers] show that poverty (over)-stimulates attention to urgent problems which results in less attention given to important problems–thus, reduce some day to day urgencies and people may become more open to devoting attention to important problems like deworming or hygiene or paying the rent which would in the not-so-long-run result in greater benefits.
Crucially, notice that SMS’s experiments are about the effect of poverty not about the poor. In other words, at least some of our discussion of the poor may suffer from the fundamental attribution error.
That bit about fundamental attribution error seems crucial. And this sort of research, which we have seen more and more of in the last decade, seems to me to offer–via rationality and science–the best non-ethical, non-moral arguments for things like affirmative action that I can imagine being put forward. No idea if they’ll change anyone’s mind but it’s good to know, as always, that social science will help “prove” things that I have known all along were “true.”
