The preceding question mentioned an experiment they are running which can help test this belief. I think you're not giving the authors enough credit by not mentioning that they clearly understand their beliefs have not been tested: "The only way to really test that is to move beyond correlational studies and conduct experiments. I’m part of a team of social scientists and neuroscientists from around the country who are planning to do just that: We’re currently fundraising for and piloting the first clinical trial of poverty reduction."
