Common questions
How does penology differ from criminology more broadly?+
Criminology studies why crime happens and who commits it, while penology narrows in on what society does after conviction, examining sentencing philosophy, prison conditions, and whether different sanctions actually reduce reoffending.
Why do rehabilitation and retribution sometimes pull sentencing policy in opposite directions?+
Retribution focuses on proportionate punishment for the act committed, while rehabilitation focuses on the offender's future behaviour, so a sentence built around one goal, such as a long fixed term, can conflict with programmes designed around the other, such as early release tied to treatment progress.
What counts as a non-custodial sanction in penology?+
Probation, community service, fines, and restorative justice conferencing are common non-custodial sanctions that penologists compare against imprisonment for cost, reoffending rates, and impact on the offender's family and employment.
