Arrow's Impossibility Theorem tells us that none of the preferential voting methods we study will satisfy all the Fairness Criteria. It is only natural, then, to look at each of the preferential voting methods and determine which of the Fairness Criteria are satisfied and which are violated. This result does not apply to nonpreferential voting systems.
These exercises are designed to help you understand how the Fairness Criteria apply to each of the voting methods.
