Interestingly, all of the definitions are a little short of true equality, true equity, true fairness of outcomes, etc. since they only take one POV into account. For a precise example, they give causal discrimination for a classifier based on whether the classifier can tell apart two subjects with the same attributes. Note that, if no classifier can tell apart the subjects, then they are genuinely indistinguishable; the universe itself cannot casually discriminate between them either.
It's interesting that folks are slowly inching towards genuine algorithmic justice, but we are still focused on defining fairness from the POV of a single judge, and not from the entire integrated awareness of every participant in the community. I suppose that the latter is uncomputable...

So some unified view of fairness is not possible (in the view that I think you want). Impossibility of Fairness: https://arxiv.org/abs/1609.07236 https://arxiv.org/abs/1609.07236 There are some frameworks to trade to balance competing fairness definitions (https://www.cs.toronto.edu/~toni/Papers/icml-final.pdf https://www.cs.toronto.edu/~toni/Papers/icml-final.pdf). Somewhat related, but you have a trade off between calibration of a binary classifier and metrics on the positive and negative classes when you don't have equal base rates and similar ratios of some characteristics in the two classes: https://arxiv.org/abs/1609.07236 https://arxiv.org/abs/1609.07236
- AlexTWithBeard 6y agoSorry, I do not understand you. Even the cake cutting problem you mentioned below takes into account both POVs. I'll also echo the sibling: what is true fairness? If it matches individual POVs, then why bother? If it doesn't then what's the use of it?
- Kednicma 6y agoTrue fairness is justice: Everybody involved agrees that everybody involved has the best possible material outcome for themselves, even under permutations of perspective. Concretely, imagine some judge Judy who is judging some dispute between some Alice and Bob. The article explores how we can evaluate Judy for fairness. However, justice is when Judy, Alice, and Bob all agree on an outcome which none of the three would change, even if they were to be forced to swap bodies in some unrelated way after the outcome is assigned.
