Why “punitivism” is a great word
The doctrine or practice of advocating for harsher and more extensive criminal penalties as the central response to wrongdoing. From Medieval Latin pūnītīvus ("relating to punishment") and the suffix -ism, forming nouns of practice or doctrine. Unlike rehabilitation, which seeks to reform and restore the offender, or restorative justice, which endeavors to heal the specific harm done, punitivism is the cold arithmetic of retribution. It is the lengthening of a sentence in a statute, the cheer at a campaign rally for more prisons, and the quiet, satisfying finality of a cell door slamming shut—a faith that society can be calibrated through the precise application of pain.
