Poverty can impair ability to think

Poverty consumes so much mental energy that people struggling to make ends meet often have little brainpower left for anything else, leaving them more susceptible to bad decisions that can perpetuate their situation, according to a new study.

"Past research has often blamed [poverty] on the personal failings of the poor. They don't work hard enough; they're not focused enough," said Jiaying Zhao, a University of British Columbia professor and one of the authors of the study, which was published Thursday in the journal Science. "What we're arguing is it's not about the individual. It's about the situation."

As part of the study, researchers conducted experiments on two groups of subjects: low- and middle-income shoppers in a mall in New Jersey, and sugar cane farmers in rural India.

In the mall experiment, shoppers underwent a battery of tests to measure IQ and impulse control. However, half the participants were first given a "teaser" question — what they would do if their car had broken down and needed $1,500 in repair — designed to put a pressing financial concerns at the forefront of their thoughts.

In India, researchers tested the cognitive capacity and decision-making of farmers before the sugar cane harvest, when they were most strapped for money, and afterwards, when they had fewer financial woes.

The results showed that people wrestling with the mental strain of poverty suffered a drop of as much as 13 points in their IQ — roughly the same found in people subjected to a night with no sleep.

"Poverty is the equivalent of pulling an all-nighter," said Harvard economist Sandhil Mullainathan, another of the study's authors. "Picture yourself after an all-nighter. Being poor is like that every day."

Mullainathan said previous research often has assumed that poor people are poor because they are somehow less capable than others, whether inherently or because of past trauma or other environmental factors in their lives. But he said what the latest study suggests is that the strain of poverty can tax the cognitive abilities of anyone experiencing it — and that those abilities return when the burden of poverty disappears.

  • Smartphone kill switches are coming

    Smartphones need kill switches. It's a relatively easy solution to the pricey (and irritating) problem of smartphone theft. But who would have thought that the big carriers would team up with Apple, Google, Microsoft, Nokia, Samsung and lots of other manufacturers to voluntarily begin adding the technology by July 2015? The cooperative spirit! It makes so much sense!

  • Why do wolves howl?

    Of all the myths that dog the wolf, none is more widely accepted than the idea that wolves howl at the moon. Images of wolves with their heads upturned, singing at the night sky, are as unquestioned as a goldfish's three-second memory or a dog's color-blindness (both also myths).

    Sen. Elizabeth Warren's populist rhetoric pumps up students about their loan burdens, but she conveniently neglects to mention the real problem - the exorbitant cost of college - much less how she's benefitted from those high prices.

  • treadmill-very-fast.jpg Tax deduction for a gym membership?

    April marks another tax season when millions of Americans will deduct expenses related to home ownership, children and education from their annual tax bill. These deductions exist because of their perceived value to society; they encourage behaviors that keep the wheels of the economy turning. So why shouldn't the tax code be revised to reward preventive health?

  • Allergies are the real midlife crisis

    One of the biggest mysteries is why the disease comes and goes, and then comes and goes again. People tend to experience intense allergies between the ages of 5 and 16, then get a couple of decades off before the symptoms return in the 30s, only to diminish around retirement age.
