My favorite article to post. The below is about 1% of the topics it covers, the premise being that algorithmic prediction traps us frozen in the past instead of ever allowing society to change.
>But the oddest is STATIC-99. It's a way of predicting whether sex offenders are likely to commit crimes again after they have been released. In America this is being used to decide whether to keep them in jail even after they have served their full sentence.
>STATIC-99 works by scoring individuals on criteria such as age, number of sex-crimes and sex of the victim. These are then fed into a database that shows recidivism rates of groups of sex-offenders in the past with similar characteristics. The judge is then told how likely it is - in percentage terms - that the offender will do it again.
>The problem is that it is not true. What the judge is really being told is the likely percentage of people in the group who will re-offend. There is no way the system can predict what an individual will do. A recent very critical report of such systems said that the margin of error for individuals could be as great as between 5% and 95%
>In other words completely useless. Yet people are being kept in prison on the basis that such a system predicts they might do something bad in the future.
