Arrow’s Impossibility Theorem, as I understand it, applies quite broadly to voting systems. To put it simply, you can’t avoid it. You just decide what trade offs you want to live with.

- jamesonquinn 8y agoArrow's theorem applies only to ordinal voting methods. Approval is not actually subject to Arrow's theorem; it's not even well-defined whether it passes the criteria. However, there are various voting impossibility theorems inspired by Arrow which do apply to approval. Most notably, Gibbard-Satterthwaite.
