This is a different problem than what people are complaining about. In fact it may be the exact opposite problem in some ways. The problem you state is that, if you base an outcome on some measure, people will manipulate that measure. E.g. a companies use college education as a proxy for competence. And now everyone has to get a college education to get a good job. Society may be better if use of these measures is banned, even if they are predictive. But this is not what's happening here. I don't see anyone claiming they changed their job, marital status, age, neighborhood, or any of the other measured factors. Just to manipulate this algorithm. These measures are probably safe to use in these circumstances, as far as this specific problem is concerned. >Justice should be individualized or it's not justice. There's no such thing as "justice". If you don't use an objective statistical algorithm to decide these things, you must use humans. And humans are far more biased and less fair. See my other comment.
