(It's linked at the bottom of this one, but I'm sure a lot of people don't get that far)
Every choice we make is a moral choice. Once we're done modelling and use that model then we make a moral choice.
For example, If you believe that lowering the debt default rates is more important than the fairness to an individual.
Then you make a moral choice. Of you believe it is OK to not give loans to Blacks because there's a largish amount of Blacks defaulting on their loans thats a moral choice.
Further more, Enscribnng truth to models is just an age old human fallacy. The truth can somewhat fit plenty of models. None of the models are truth.
