Arrow's impossibility theorem suggests that:
A)any voting system society adopts for aggregating the preferences of its members will be flawed
B)a voting system will be ideal if some form of dictatorship is allowed
C)a voting system will be ideal if the properties of intransitivity and dependence of irrelevant alternatives are satisfied
D)none of the above

Question

Quizplus · Accepted Answer

Arrow's impossibility theorem states that there is no perfect voting system that can satisfy all desirable properties at the same time, and that any voting system that tries to aggregate the preferences of a group of individuals will inevitably have flaws or limitations. Therefore, choice A is the correct answer. Choice B is not correct, as it suggests that a form of dictatorship might be necessary for an ideal voting system, which is not desirable in a democratic society. Choice C is also incorrect, as Arrow's theorem shows that even if certain properties such as transitivity and independence of irrelevant alternatives are satisfied, there will still be other limitations or issues with the voting system.
