A recent study found that black children have less grey matter in their brains than white children. They researchers then came to the conclusion that this was the result of the stresses of poverty, drugs, and violence, which was caused by systemic racism. How can you draw that conclusion? It seems to me as if they began with the conclusion, then went looking for the support.
I can think of several alternative conclusions.
- Cause and effect is reversed. Perhaps it is the lack of grey matter that causes the poverty and violence.
- Perhaps it is that poverty and violence were caused by something else. Why does it have to be racism, and what supporting evidence do you have?
Black children experienced more traumatic events, family conflict, and material hardship on average compared with White children, and their parents or caregivers had lower educational attainment, lower income, and more unemployment compared with those of White children. Black children showed lower amygdala, hippocampus, and PFC gray matter volumes compared with White children. The volumes of the PFC and amygdala, but not the hippocampus, also varied with metrics of childhood adversity, with income being the most common predictor of brain volume differences. Accounting for differences in childhood adversity attenuated the magnitude of some race-related differences in gray matter volume.
OK. So how did you determine cause and effect? Were the black children born with less grey matter than whites? Did the amount of grey matter decline over time? Did you compare black children who were wealthy (say, Jayden Smith or the Obama girls) to white children who were poor, to see if there were correlations there? How about including other races? Asians?
Nope. Instead, the study began with the following assumptions:
Current U.S. Census data show that Black households, on average, have a lower median income, lower educational attainment, and higher rates of unemployment and poverty compared with White households. Moreover, research suggests that Black children are more likely to be exposed to trauma and domestic violence and are more likely to have a parent who died, an incarcerated parent, or divorced or separated parents compared with White children. Additionally, research has shown that Black children live in disproportionately disadvantaged neighborhoods and are more likely than White children to be exposed to neighborhood violence. These racial disparities are not random. Rather, they are deep-rooted structural inequalities that result from a history of disenfranchisement of racially minoritized groups (e.g., slavery, segregation) that reinforce themselves through societal norms and practices (i.e., systemic racism)
(highlighting added)
I was with them on the other evidence. Yes, there is evidence that black children are likely to be poor, have incarcerated parents, and lower intelligence. I agree. What they are essentially saying is that blacks are poor, less intelligent, and more likely to be criminals than are whites, and that there is a biological and physiological basis for this. That’s exactly what I have been saying for years. What I have a problem with is the conclusion that is unsupported by any evidence presented by this so-called study- that it’s white people’s fault.
This seems like junk science with no control group and little in the way of actual, well, science. When I was a teacher, had one of my students turned in an unsupported conclusion like that one, it likely would have received a poor grade.
