Aporia · The End of the Mass Incarceration Myth

A peer-reviewed study published in Nature Human Behaviour argues that the US prison population has been declining since 2000, with a significant reduction in racial disparities in new prison admissions. According to the study, annual new prison admissions for black people fell by more than for white people during this period. The research suggests that a decrease in violent crime rates is driving lower prison admissions, rather than increased leniency towards offenders. This challenges the conventional narrative of "mass incarceration" and its portrayal of the US criminal justice system as inherently racist.

Story summary

The US prison population has been declining for two decades, with annual new prison admissions for black people falling more than for white people during that period. This trend suggests a shift away from the "mass incarceration" narrative, which claims that the criminal justice system is unfairly targeting and trapping black individuals. A recent peer-reviewed study by sociologists at the universities of Wisconsin and Iowa found that the US was already moving towards less incarceration, including among black offenders, when national concern over "mass incarceration" peaked in the mid-2010s. This challenges conventional wisdom on the left, which often calls for prison abolition as a key plank in its platform, exemplified by the Democratic Socialists of America (DSA). The study's findings suggest that crime and incarceration rates are declining together, potentially marking a virtuous cycle rather than a broken or racist system.
