Can Gambling Studies Teach Us Something About Education Metrics?

A recent study [Why play a losing game? Study uncovers why low-income people buy lottery tickets] as to why the poor gamble so much comes to some interesting conclusions.
A new Carnegie Mellon University study sheds light on the reasons why low-income lottery players eagerly invest in a product that provides poor returns.

In the study, published in the July issue of the Journal of Behavioral Decision Making, participants who were made to feel subjectively poor bought nearly twice as many lottery tickets as a comparison group that was made to feel subjectively more affluent. The Carnegie Mellon findings point to poverty's central role in people's decisions to buy lottery tickets.

"Some poor people see playing the lottery as their best opportunity for improving their financial situations, albeit wrongly so," said the study's lead author Emily Haisley, a doctoral student in the Department of Organizational Behavior and Theory at Carnegie Mellon's Tepper School of Business. "The hope of getting out of poverty encourages people to continue to buy tickets, even though their chances of stumbling upon a life-changing windfall are nearly impossibly slim and buying lottery tickets in fact exacerbates the very poverty that purchasers are hoping to escape."

The researchers influenced participants' perceptions of their relative wealth — or lack thereof — by having them complete a survey on their opinions of the city of Pittsburgh that included an item on annual income. The group made to feel poor was asked to provide its income on a scale that began at "less than $100,000" and went upward from there in $100,000 increments, ensuring that most respondents would be in the lowest income category. The group made to feel subjectively wealthier was asked to report income on a scale that began with "less than $10,000" and increased in $10,000 increments, leading most respondents to be in a middle or upper tier.

Participants, who were recruited at Pittsburgh's Greyhound Bus terminal, were paid $5 for completing the survey and given the opportunity to buy as many as five scratch-off lottery tickets. The experimental group purchased an average of 1.27 lottery tickets, compared with 0.67 tickets bought by the members of the control group.

A second experiment reported in the paper found that indirectly reminding participants that, while different income groups face unequal outcomes in education, jobs and housing, everyone has equal chances of winning the lottery induced an increase in the number of lottery tickets purchased. The group given this reminder purchased 1.31 tickets, compared with 0.54 for the group not given such a reminder.
It seems to me that an unexpected consequence of NCLB's metrics (aside from being bogus) is that they label schools as failures. Instead of creating a perspective of the school within a context of the norm.

Secondly, students in poor school districts might score better if they were encouraged to study because their IQ indicated they were far more normal within the school population than any other signals in their lives might lead them to believe.
