The more you study biology and child development, the more this makes sense:
Early childhood is a”crucial time for establishing the brain architecture that shape’s children’s future cognitive, social and emotional well-being,” the study says.
“Children growing up in a disadvantaged setting show disproportionate levels of reactivity to stress, and it shows at the level of hormonal studies, neurological brain imaging studies and at the level of epigenetic profiling,” said Thomas Boyce, of the University of British Columbia.
The researchers studied data on more than 1,500 individuals born between 1968 and 1975 taken from a 40-year demographic study of US households that measured family income during every year of childhood, educational attainment, what level people reached in their careers, plus crime and health as adults.
They found “striking differences” in how the children’s lives turned out as adults, depending on whether they were poor or comfortably well-off before the age of six.
Not having the raw statistical data makes it dubious as to just what levels of causation are involved, but this phenomenon surely has a huge number of variables. Worth investigating further, nonetheless. via Saletan
