Prison subcultures have been described as antisocial, with ties to violence and gang membership. In extreme cases, research has also suggested that prison subcultures contribute to incarcerated people joining radical groups or embracing violent extremist beliefs. A new study examined the relation between prison subcultures and prison radicalization based on interviews with incarcerated men and correctional officers in Canada. The study found that several features of these subcultures make incarcerated Canadians resilient to radicalized and extremist messaging.
