Deterrence and Individual Differences Among Convicted Offenders

Conflicting evidence exists on how criminal propensity moderates deterrent effects, and there is little empirical evidence on this issue from relatively experienced offenders. This study tested how variation in criminal propensity (operationalized as “low self-control”) moderates deterrent effects in a sample of convicted offenders in New Jersey’s Intensive Supervision Program in 1989 and 1990. Offenders’ perceptions of the risks and consequences from violating ISP were associated with whether they successfully completed ISP. Moreover, lower self-control did not diminish, and if anything, enhanced these deterrent effects.
