Two central criteria of group fairness -- error-rate parity and calibration within subgroups -- usually cannot be satisfied at the same time. We introduce a natural way to relax these notions, which reveals the tradeoffs between them and suggests a range of new, optimally fair prediction rules. This relaxation also highlights when some fairness requirements must fail. Finally, we turn to the surprising question of when and how it is even possible to make fair decisions based on fair scores.
