Have you always felt that you could make of your life pretty much what you want to make of it? Once I make up your mind to do something, do you stay with it until the job is completely done? And when things don’t go the way you want them to, do you just work harder? And one last question – are your poor, or working class, or live in a highly segregated area? If you strongly agree with the first questions, and answer yes to the last one, your coping is likely putting you at greater risk for a raft of health problems. That’s a key finding of Duke University epidemiologist Sherman James, who describes what he terms ‘John Henryism’ in this Social Science Bites podcast. The health effects, which James has studied since the 1980s, have come into sharper focus as the Coronavirus pandemic exacts a disproportionate toll on communities of color in the United States. Based on the John Henryism hypothesis, James tells interviewer David Edmonds, members of those communities are likely to develop the co-morbidities which help make COVID more deadly. And since many of them have to physically go to work, John Henryism helps “elucidate what some of these upstream drivers are.” James defines John Henryism as “strong personality disposition to engage in high-effort coping with social and economic adversity. For racial and ethnic minorities … who live in wealthy, predominantly white countries – say, the United States – that adversity might include recurring interpersonal or systemic racial discrimination.” It can be identified by using James’ John Henryism Active Coping Scale, (JHAC12, pronounced ‘jack’), which asks 12 questions with responses from ‘strongly agree’ to ‘strongly disagree’ on a 5-point Likert scale. High-effort coping, over years, results in excessive “wear and tear” on the body, damaging such things as the cardiovascular system, the immune system, and the metabolic system. Focusing on the cardiovascular system, James notes that this “enormous outpouring of energy and release of stress hormones” damages the blood vessels and the heart. James notes that the damage doesn’t occur solely because someone is a Type A personality – it’s the interaction with poverty or segregation that turns someone from a striver to a Sisyphus (with the attendant negative effects on their cardiovascular health). In fact, James says, research finds that having resources and a John Henry-esque personality does not lead to an earlier onset of cardiovascular disease. The eponymous John Henry is a figure from American folklore. The ‘real’ John Henry probably was a manual worker, perhaps an emancipated slave in the American South, James explains. His legendary doppelganger was a railroad worker, “renowned throughout the South for his amazing physical strength,” especially when drilling holes into solid rock so that dynamite could be used. A boss challenged John Henry to compete against a mechanical steam drill. It was, says James, “an epic battle of man – John Henry – against the machine. John Henry actually beat the machine, but he died from complete mental and physical exhaustion following is victory.” A folk song memorializes the battle. As one version (there are many, but all telling the same story) recounts: John Henry he hammered in the mountains His hammer was striking fire But he worked so hard, it broke his heart John Henry laid down his hammer and died, Lord, Lord John Henry laid down his hammer and died That narrative – dying from the stresses of being driven to perfection but in a dire environment – the Jim Crow South – gave its name to James’ hypothesis. James himself grew up in small town in the rural American South, beginning his higher education in the early 1960s at the historically Black Talladega College near Birmingham, Alabama. Birmingham was the heart of the civil rights struggle in the Civil Rights era, and James was an activist, too. He decided then that “whatever I did would have to have some bearing on social justice, on working to ma
