Scholars examining prisoners’ "secondary adjustments" have often emphasized prisoners’ "resistance" to the prison regime, particularly their agentic acts that frustrate the prison’s rules, goals, or functions. While these agency-centered accounts offer an important corrective to the understanding of prisons as totalizing institutions, they may go too far. I argue that scholars have overused (and misused) the term "resistance" to describe certain prisoner behaviors, creating both analytical and normative consequences. Instead, I suggest the concept of "friction" more accurately describes the reactive behaviors that occur when people find themselves in highly controlled environments.
