Principle 1b: Assess Actuarial Risk/Need and Responsivity
What exactly is “actuarial” anyway? “Actuarial” refers to a set of statistics that calculate probabilities of a specific event. The reason probability statistics are emphasized is because human judgment regarding the risk of future crime is typically quite bad, in part because emotions and other biases (see our Risk Principle-Simplified for a more detailed discussion) get in the way. Many authors have done an admirable job of describing the Risk, Need, and Responsivity (RNR) principles. Perhaps it is due to our industry’s creative words (e.g.,“criminogenic” means crime-creating), but our experience is that trainees struggle to truly understand the concepts and have an even tougher time applying it to their daily operations and worldview.
