In his latest column, David Brooks acknowledges that 50 years worth of gigantic policies driven by flawed social science has produced disappointing results. He is, however -- like those perpetually convinced that the latest financial bubble is not a bubble at all -- absolutely convinced that the latest social science, this time, can produce effective policies.
At the center of his argument is research by Eldar Shafir of Princeton and Sendhil Mullainathan of Harvard that finds "scarcity produces its own cognitive traits." For example, if you are poor, you are more likely to know the starting taxi fare or make complicated trade-offs involving milk and orange juice. This imposes enormous cognitive demands, crowding out other cognitive function. He doesn't explain what policies follow from this insight, but the most obvious would be those freeing poor people from these difficult choices. He does re-iterate his belief that "we need to design policies around" the knowledge that "we each have multiple selves" that "emerge or don’t emerge" in specific contexts.
It is worth noting that generations of folk lore would contradict any policy conclusions of scarcity research: Those we celebrate as having lifted themselves from poverty, do so, largely, because, not in spite, of their acute -- even obsessive -- attention to the kind of questions Brooks is convinced are obstacles.
Above all, as previously argued, pre-scientific teachers well understood our complex and divided natures. For that reason, they encouraged beliefs -- in particular: virtue and personal responsibility -- that supported our better angels. There is no evidence that social "science" ever has, or will, improve on what it displaced.
