Earlier quoted context omitted.
We're doing credit scoring at the Danish bank i work at. One of our requirements is that the model and architecture has to be able to provide explanations for why yohr rating is whatever it is. Both to regulators, internal auditors, and customers. Personally, i thimk denying people a loan is a pretty impactful decision on peoples life. They deserve a reason.
There are three basic reasons people don't get a loan: - They already have too much debt - They don't earn enough to pay it off - They have a history of not paying off their debts. This should not be hard to explain to most people.
If only. In practice it's more like "They don't have a history of paying off their debts", which crucially means if you don't have a history of being in debt then you have no history of paying it off, and therefore you're considered high risk. Thus you get otherwise-nonsencial behaviours like taking out a loan only for the reason of paying it off.
