How does incapacitation seek to prevent repeat offenders from committing additional crimes?

In the context of law, incapacitation seeks to prevent repeat offenders from committing additional crimes by rendering them physically unable to do so. This is achieved through methods that remove the individual from society or otherwise restrict their capacity to act, including execution, banishment, or lengthy periods of incarceration.1

This approach is frequently applied to habitual offenders who have committed multiple crimes, as well as individuals deemed dangerous and likely to commit grave, violent acts if left unrestrained. While the goal is to ensure public safety by physically restraining the offender, the principle remains controversial due to the difficulty of accurately identifying which individuals will reoffend and the challenge of reconciling incapacitation with other legal principles, such as equal retribution. Other methods, such as chemical castration for sex offenders, have also been explored, though their effectiveness often depends on whether they are combined with psychological treatment.1
