Unknown to most people, computer algorithms are being used now to make decisions in many places about how individual people get treated. They are already being used in several states to help sentence persons convicted of a crime. They are used by loan companies to decide who gets a loan. But these algorithms have many potential pitfalls and may not be the fairest at making decisions for the people who's lives are affected. Quick imaginary example to illustrate the point. Suppose African Americans statistically have a higher prevalence of using a certain type of drug. The computer algorithm notices that defendants who have been convicted of crimes involving this type of drug are more likely to have a higher reoffending rate when it comes to violent crimes. Essentially now the computer is using unfair discrimination to sentence some criminals to longer sentences, even though there is no direct cause and effect connection between using that particular type of drug and committing a violent crime.
