Sherman James

Sherman A. James, an African American epidemiologist and health researcher, is renowned for his “John Henryism” hypothesis, which links premature mortality among African Americans to chronic stress from systemic discrimination and racism. The concept draws from the folk hero John Henry, a Black “steel-driving man” from the 1870s who, according to legend, defeated a steam-powered rock-drilling machine in a race but died from the exertion, symbolizing the toll of relentless effort against overwhelming odds.

In his 1983 study at the UNC Gillings School of Global Public Health, James surveyed 132 working-class African American men in the South, using a 12-item John Henryism Active Coping Scale to measure their belief in overcoming environmental challenges, including racism, through hard work and determination. The scale assessed traits like mental and physical vigor, tenacity, and commitment to goals despite adversity. His findings showed that African American men with high John Henryism—intense effort to succeed against discrimination—often faced negative health outcomes, such as hypertension and heart disease. James concluded that social environment, not genetics, primarily drove their shorter life expectancy, significantly shaping discussions on social determinants of health.

James earned his psychology doctorate from Washington University in St. Louis in 1973 and joined the epidemiology department at UNC, where he conducted his foundational John Henryism research. In 1989, he moved to the University of Michigan School of Public Health as a professor of epidemiology, later named the John P. Kirscht Collegiate Professor. In 1995, he founded the Center for Research on Ethnicity, Culture, and Health (CRECH), which he noted was likely the first U.S. public health academic unit to study how racism, cultural differences, ethnicity, and socioeconomic factors interact to influence health disparities. From 1999 to 2003, he chaired the Department of Health Behavior and Health Education and served as a senior research scientist at the Institute for Social Research.

James’ John Henryism hypothesis has profoundly influenced public health, sociology, and psychology, highlighting how systemic inequities contribute to health disparities. The John Henryism Scale remains a key tool in health research, applied to various groups facing systemic stress. His work has earned numerous accolades and inspired researchers to explore the interplay of social, environmental, and biological factors in health outcomes. By emphasizing structural racism as a public health issue, James has driven policy discussions on health equity, leaving a lasting legacy through CRECH and his broader scholarship, which continues to inform racial justice and health disparities research.
