How Algorithms Can Beat Back Prejudice in Companies and Courts

The way the justice system sets bail for defendants is far from a hard science, and the numbers bear that out: African Americans between the ages of 18 and 29, for example, are given much higher bail amounts than any other demographic, a 2012 study found.

Racism, conscious or not, also exists in the labor market. In a 2009 study published in the American Sociological Review, white, black and Latino job applicants were given equivalent resumes to apply for hundreds of entry-level jobs in New York City. The results found that black applicants were half as likely as equally qualified whites to be asked for a callback or given a job offer.

In an effort to combat these often undetected biases and predispositions, both the criminal justice system and companies looking to hire are turning more and more to technology.

After two years of testing, the Laura and John Arnold Foundation is introducing a new tool called the Public Safety Assessment to help judges make bail decisions. The foundation said the tool, built by analyzing data from more than 1.5 million cases across 300 U.S. jurisdictions, assesses a defendant based on factors related to criminal history, current charge and current age. Its algorithm gives defendants two scores — one for the probability of them committing a crime, especially a violent one; the other for the risk that they will skip court dates. In pilot jurisdictions, the algorithm was shown to ignore both race and gender.

Since many pretrial release decisions are made subjectively without risk assessment, “the result, although unintended, is that many of the individuals who are held in jail before trial pose little risk to public safety, while many violent, high-risk defendants are released into the community,” the foundation said in announcing the new assessment.

The foundation says its tool, developed at a cost of $1.2 million, can instead provide “reliable, predictive information about the risk that a defendant released before trial will engage in violence, commit a new crime, or fail to return to court.” The assessment will be rolled out to 21 jurisdictions, including Arizona, Kentucky and New Jersey as well as the cities of Charlotte, Chicago and Phoenix, the foundation announced last week.

The idea of incorporating scientific measures of risk into bail decisions carries some obvious appeal, and some lawyers and law enforcement groups have supported the use of such tools, The New York Times reported. But only about 10 percent of courts now use such “evidence-based risk-assessment instruments” when deciding whether to release or detain defendants, according to the Arnold Foundation.
