The Poor Do Have Self Control
One of the myths about the poor is that they cannot defer gratification for greater future benefits.
Well, scientists have found a way to objectively test for the ability to handle stress, it involves "Vagal Tone", activity of the Vagus nerve, which is an indicator of how well people handle stress.
What they discovered is that poor children who are best able to think things through the take the immediate reward, while rich kids will delay gratification.
It turns out that poor children use a different calculus: Having never experienced the stability of their more fortunate cohorts, they go for the the immediate payoff, because experience has shown them that the any plans for the future will make their plans moot:
In the late 1960s, Walter Mischel, a researcher at Stanford University, invited several hundred children to participate in a game in which they were given a choice: They could eat one sweet right away, or wait and have two a little later. Initially, the goal was simple: to see how and why people (kids in this case) delayed gratification. But after the end of the experiment, Mischel began to check in with as many of the participants' families as he could, and over the following decade he learned that his little experiment probably had much larger implications than he had anticipated.This is rational behavior, not evidence of lack of moral fiber.
Many of the children had trouble resisting the single, immediate treat (a marshmallow), which was to be expected. The magnetic force that exists between kids and candies is no secret. What was surprising, however, was that that tendency — the inability to forego something good right now in exchange for something better in a bit — was associated with all sorts of negative life outcomes, including lower levels of academic achievement and higher rates of obesity.

The realization has sparked concerns that poverty begets a certain level of impulsiveness, and that that tendency to act in the moment, on a whim, without fully considering the consequences, makes it all the more difficult for poor children to succeed. But there's an important thing this discussion seems to miss. Poor kids may simply not want to delay gratification. Put another way, their decisions may not reflect the sort of impulsive nature we tend to attribute them to.
"When resources are low and scarce, the rational decision is to take the immediate benefit and to discount the future gain," said Melissa Sturge-Apple, a professor of psychology at the University of Rochester who studies child development. "When children are faced with economic uncertainty, impoverished conditions, not knowing when the next meal is, etc. — they may be better off if they take what is in front of them."
A recent two-part study conducted by Sturge-Apple shows how the tendency of poorer children to pounce on immediate rewards might not be the result of impulsiveness but rather of careful consideration.
In the first experiment, she monitored the heart rate of 200 low-income 2-year-olds. The monitoring allowed her to approximate each child's vagal tone — a measure of the activity of the vagus nerve, which has been shown to indicate how well a given individual performs under stress (i.e., reads social cues, reacts to environmental contexts, and adjusts behaviors). High vagal tone is good: it suggests a heightened ability to act relatively calmly under stress. Low vagal tone is bad: it suggests just the opposite.
Two years later, at the age of 4, the same children were presented with a choice. Each was sat a table where two plates and a bell were placed. One plate held two M&Ms, while the other held five. The children were told that they could either ring the bell and have the two M&Ms immediately or enjoy the plate of five as soon as the experimenter returned.
Interestingly, each child's vagal tone appeared to have a significant effect on their decision. But — and this is an important but — it didn't have the sort of effect many would have imagined. The higher the child's vagal tone — the greater, in other words, a child's ability to act calmly under pressure — the more likely the child was to ring the bell. The calmer the children were to think it through, the more likely they were to choose the immediate reward.
………
The children born to college-educated mothers of high socioeconomic status acted exactly as one would expect. The higher their vagal tone, or calmness under stress, the more likely they were to hold out for the five extra M&Ms. For children born to non-college-educated mothers of low socioeconomic status, on the other hand, the outcome was exactly the opposite. The higher their vagal tone, the less likely they were to wait.
The chart below, plucked from the study, shows just how stark the divergence is.
If you don't know where your next meal is coming from, you eat whenever you can.
QED.
