Violence risk instruments are used in numerous countries to estimate an individual's risk of reoffending. The racial fairness of violence risk instruments has received increasing attention due to ostensible differences among Anglo populations and racial minorities (e.g. African Americans and Indigenous populations). Fairness, which has numerous definitions (sensitivity fairness, error rate balance, calibration, predictive parity, statistical parity), can affect a risk instrument's utility in varying ways. This literature review explored how notions of fairness are discussed in the risk instrument literature with a specific focus on racial fairness. It also examined and critiqued the varying proposed resolutions to increase fairness. Many of these forms of fairness were found to be rarely satisfied in the literature. Further, the complications in achieving multiple forms of fairness simultaneously and the challenges of optimising both fairness and accuracy are discussed. Last, proposed solutions to increase racial fairness were often found to encompass significant limitations. Future directions for racial fairness in risk instruments are discussed, with a focus on exploring the trade-offs among varying fairness definitions and among fairness and accuracy.

Violence risk assessment tools are used around the world with people who have committed crimes to determine the risk factors that may have contributed to their offending. These tools can carry great consequences for people's liberty. Violence risk assessment tools are also used with Indigenous people who are overrepresented in the Canadian justice system. A major issue with these risk assessment tools is that they do not use a colonial lens to understand the underlying mechanisms of violence. Using the Structured Assessment of Violence Risk in Youth (SAVRY) as an example, we examined how colonialism underlies risk and protective ratings. Colonialism increases the probability that Indigenous youth will be rated higher on some risk factors on the SAVRY. Novel interventions to reduce Indigenous overrepresentation include addressing the colonial factors behind violence risk and protective factors. Given that colonialism underlies scores on risk assessment tools, service providers need to link risk ratings to colonialism in their service formulations, carefully attend to culturally relevant factors, and provide interventions and support that specifically address colonialism. Suggestions for future research that include Indigenous community involvement are also provided. A short case analysis, cultural formulation and treatment suggestions are provided as an illustration.
