I think there is some huge motivation on the part of the research here to explain why certain segments of the population remain in a loop of poverty and violence. I think social factors can adequately explain the problems we see. Perhaps there is a genetic component as well to why some groups do better than others, but research of that kind routinely gets the authors in trouble. Here we can have a quasi -genetic predisposition explanation that does away with the shame of having bad genes and suggests that it is society’s fault for not preventing the stressors in earlier generations that lead current generations to underperform.
What is a little strange is the implication that the changes to the epigenome stay permanently, of course only if they are negative changes.
