Is it impossible to be fair?
23 aug. 2019 - This post is about fairness. In particular, it's about some interesting recent results, which came out of attempts to check whether particular automated prediction tools were fair, but which seem to have a more general consequence: that in a wide variety of situations it's impossible to make fair predictions. As Kleinberg et al. put it in their abstract: "These results suggest some of the ways in which key notions of fairness are incompatible with each other."
