"Why can't more poor people escape poverty? Psychologists have a radical new explanation," reports The New Republic. In the 1990s, studies suggested that exerting willpower in one context made it more difficult to exert it in others soon afterwards. Hungry subjects, for instance, were offered a choice between radishes and chocolate; the half who were instructed to take the radishes were found to be less able than the control group to focus on a difficult geometry problem. (Or maybe they were just too hungry?) The conclusion: exerting self-control exacts a psychic cost and leaves you weaker.
Later researchers expanded the concept to include any kind of trade-off decision, not merely a difficult resistance to temptation. Resolving conflicts among choices creates mental fatigue. Princeton psychologist Eldar Shafir then extended the theory to explain why the poor stay poor: when you lack disposable income, you can't have everything you want, but have to choose to do without an alternative almost every time you spend a dollar. As a result, the poor get tired brains and can't get ahead. But if you're rich, "deciding whether to buy the [product] only requires considering whether you want it, not what you might have to give up to get it."
I find this logic hard to follow. For one thing, the rich are if anything overwhelmed by choice, simply because they have the income to buy so many things beyond the kind of basic necessities whose purchase can be put on something like autopilot. For another, there seems to be no evidence that people who've managed to lift themselves out of poverty are mysteriously possessed of a larger store of this precious, depletable stock of willpower.
And naturally the theory lends itself to a justification of exerting additional control over the people who are unlucky enough to become the objects of our charity:
All of this suggests that we need to rethink our approaches to poverty reduction. Many of our current anti-poverty efforts focus on access to health, educational, agricultural, and financial services. Now, it seems, we need to start treating willpower as a scarce and important resource as well. . . . [M]oney itself can go a long way toward altering the dynamic that leads to willpower depletion among the poor. Government transfers of money have proven successful in Mexico and Brazil, for instance. In particular, attaching conditions to these transfers—such as requiring school attendance, regular clinic visits, and savings behavior—may allow for an end-run around the kind of willpower-based poverty traps that too frequently seem to end with the poor making unwise decisions.
