Risk assessment strategies are becoming more complex and accurate, but remain problematic in terms of how such instruments are promoted and used. Currently, many people doing risk assessments of sex offenders are using actuarial (statistical) tests developed in other countries or on unique populations, with offenders very different from the test-development sample. This is clearly unethical and inappropriate and could result in needless prolonging of incarceration or the premature release of a dangerous individual and possible needless victimization of others. Other measures, such as the structured clinical guidelines may provide a short-term solution to the widespread use of unguided professional judgement and the lack of population-based actuarial tests.
