Prior Record and the Risk of Recidivism
It is generally assumed that prior convictions provide a useful proxy for the offender’s risk of committing further crimes, and as a general proposition that assumption is well supported by research. But as this chapter shows, there is much less research on how well particular prior record formulas predict recidivism risk. This chapter identifies the elements of guidelines criminal history scores that appear to be designed to measure risk, reviews the limited research assessing the accuracy of criminal history scores and score components as predictors of subsequent offending, and examines the closeness of fit between predicted increases in risk, as the criminal history score rises, and the increments in sentence severity that are prescribed by grid-based guidelines systems. The chapter also argues against the use of rigid prior record enhancement formulas, and in favor of giving judges power to adjust sentences to take into account case-specific variations in recidivism risk.
