In social choice theory, Arrow’s impossibility theorem, the general possibility theorem or Arrow’s paradox is an impossibility theorem stating that when voters have three or more distinct alternatives (options), no ranked ordervoting system can convert the ranked preferences of individuals into a community-wide (complete and transitive) ranking while also meeting a pre-specified set of criteria, unrestricted domain, non-dictatorship, Pareto efficiency, and independence of irrelevant alternatives.

Remember to vote though.
