Arrow's impossibility theorem tells us:

Question

Quizplus · Accepted Answer

Arrow's impossibility theorem states that no voting system can meet all of the criteria for an ideal system when aggregating the preferences of voters between three or more options. Therefore, choice A is the correct answer. Choice B is incorrect because Arrow's theorem implies that most voting systems cannot meet the criteria for an ideal system. Choice C is also incorrect because Arrow's theorem does not assume that political pressures will corrupt a voting system, but rather that impossibility arises from the criteria for an ideal system. Choice D is incorrect because Arrow's theorem is a well-accepted theorem in social choice theory.
