If "these truths, while statistically correct, may fail our test for what we consider to be philosophically fair" then perhaps it is your philosophy of 'fairness' that is biased and incorrect.
So my philosophy of "fairness" here is that we should hold people responsible only for their own actions, which, while off-the-cuff, seems like it would agree with most justice systems. If we included demographic information in our models, we would effectively be holding individuals responsible for the actions of others, which doesn't seem sound.
