Why rich kids are so good at the marshmallow test, by @JessicaCalarco
The failed replication of the marshmallow test does more than just debunk the earlier notion; it suggests other possible explanations for why poorer kids would be less motivated to wait for that second marshmallow. For them, daily life holds fewer guarantees: There might be food in the pantry today, but there might not be tomorrow, so there is a risk that comes with waiting. And even if their parents promise to buy more of a certain food, sometimes that promise gets broken out of financial necessity.
Revisiting the Marshmallow Test: A Conceptual Replication Investigating Links Between Early Delay of Gratification and Later Outcomes – Tyler W. Watts, Greg J. Duncan, Haonan Quan, 2018
We replicated and extended Shoda, Mischel, and Peake’s (1990) famous marshmallow study, which showed strong bivariate correlations between a child’s ability to delay gratification just before entering school and both adolescent achievement and socioemotional behaviors. Concentrating on children whose mothers had not completed college, we found that an additional minute waited at age 4 predicted a gain of approximately one tenth of a standard deviation in achievement at age 15. But this bivariate correlation was only half the size of those reported in the original studies and was reduced by two thirds in the presence of controls for family background, early cognitive ability, and the home environment. Most of the variation in adolescent achievement came from being able to wait at least 20 s. Associations between delay time and measures of behavioral outcomes at age 15 were much smaller and rarely statistically significant.

How Barack Obama failed black Americans, William A. Darity Jr.
The “acting white” libel is symptomatic of a more general perspective—a perspective that argues that an important factor explaining racial economic disparities is self-defeating or dysfunctional behavior on the part of blacks themselves. And Barack Obama continuously has trafficked in this perspective. Of course, there are some black folk who engage in habits that undermine their potential accomplishments, but there are some white folk who engage in habits that undermine their potential accomplishments as well. And there is no evidence to demonstrate that are proportionately more blacks who behave in ways that undercut achievement, especially since it is clear that blacks do more with less. Nevertheless, Obama consistently has trafficked heavily in the tropes of black dysfunction. Either he is unfamiliar with or uninterested in the evidence that undercuts the black behavioral deficiency narrative. These tropes, in my view, do malicious work.
