“…Over 80 years ago, and three decades before the start of a period in the United States known as mass incarceration, Clemmer (1940) identified the "atomized world of prison life" and its system of self-governing and institutionalized socialization among prisoners, which he termed "prisonization." Prisoners undergo prisonization by adapting to and adopting the formal and informal norms, mores, and customs of prison life, allowing for the creation of what Sykes (1958Sykes ( /2007) identified as prison subcultures, later known as "cars" within institutions across California and later Arizona and elsewhere (Bloch and Olivares-Pelayo, 2023). In contemporary prison parlance, strict adherence to the norms of prisonization is known as "the politics" or "reglas" (Skarbek, 2014), which comprises a general "convict code" of fervently enforced rules, ethics, and responsibilities (Trammell, 2012), including with whom one can bunk, eat, exercise, trade, play cards, buy and sell contraband, and even fraternize, as well as the spaces one can inhabit on a daily basis, including cells, handball courts, mess halls, day room tables, and barbers' chairs.…”
