In Memoriam: James H. Sidanius, 1945–2021

James Sidanius, John Lindsley Professor of Psychology in Memory of William James and professor of African and African American studies at Harvard University, passed away on June 29, 2021, at age 75. Sidanius became a Faculty Associate in 2017, after joining the Harvard faculty in 2006. Much of his work focused on how inequality and oppression are built on hierarchies such as age, gender, race, ethnic group, class, and more. Sidanius pioneered the idea of social dominance orientation—the extent to which a person will support or fight against hierarchy in a social system.
