Algorithmic Risk Assessment in the Hands of Humans
研究法官在量刑中使用算法风险评估的影响，发现法官会偏离算法建议，导致公共安全和监禁率无显著改善，但严格遵循算法可减少监禁却增加对青少年的刑罚。
We evaluate the impacts of adopting algorithmic risk assessments in sentencing. We find that judges changed sentencing practices in response to the risk assessment, but that discretion played a large role in mediating its impact. Judges deviated from the recommendations associated with the algorithm in systematic ways, suggestive of alternative objectives. As a result, risk assessment did not lead to detectable gains in terms of public safety or reduced incarceration rates. Using simulations, we show that strict adherence to the sentencing recommendations associated with the algorithm would have had benefits (less incarceration) but also some costs (increased sentences for youth).
