If race and _____ are correlated, won't any predictor of _______ also be a predictor of race? That logic could be used to even ban using income as a predictor.

- teruakohatu 4y agoEverything is corrolated [1]. So putting that aside, context matters. Contextually there is no reason to suspect that a phone operating system has anything to do with anyone's ability to repay a loan, anymore than the color of their car or their eye color. Income and existing debt does, obviously. What you don't want, and what is not legal, is denying a loan because of nonsense predictors that happen to be very strongly corrolated to race and very weakly corrolated to the ability to repay a loan. If color of car, or operating system, is a strong predictor then the model is probably being overtrained on the training data and probably wouldn't generalise well in the real world.
