David Brooks has a brilliant column today about research into behavioral psychology. I highly recommend reading this because it is really fascinating:
"Let’s say you want to reduce poverty. We have two traditional understandings of poverty. The first presumes people are rational. They are pursuing their goals effectively and don’t need much help in changing their behavior. The second presumes that the poor are afflicted by cultural or psychological dysfunctions that sometimes lead them to behave in shortsighted ways. Neither of these theories has produced much in the way of effective policies.
Eldar Shafir of Princeton and Sendhil Mullainathan of Harvard have recently, with federal help, been exploring a third theory, that scarcity produces its own cognitive traits.
A quick question: What is the starting taxi fare in your city? If you are like most upper-middle-class people, you don’t know. If you are like many struggling people, you do know. Poorer people have to think hard about a million things that affluent people don’t. They have to make complicated trade-offs when buying a carton of milk: If I buy milk, I can’t afford orange juice. They have to decide which utility not to pay.
These questions impose enormous cognitive demands. The brain has limited capacities. If you increase demands on one sort of question, it performs less well on other sorts of questions.
Shafir and Mullainathan gave batteries of tests to Indian sugar farmers. After they sell their harvest, they live in relative prosperity. During this season, the farmers do well on the I.Q. and other tests. But before the harvest, they live amid scarcity and have to think hard about a thousand daily decisions. During these seasons, these same farmers do much worse on the tests. They appear to have lower I.Q.’s. They have more trouble controlling their attention. They are more shortsighted. Scarcity creates its own psychology."
Read the whole column. It is well worth the time and effort.
