= McKelvey–Schofield chaos theorem
{wiki=McKelvey–Schofield_chaos_theorem}
The McKelvey–Schofield chaos theorem is a result in social choice theory that addresses the conditions under which certain voting systems can produce chaotic outcomes. This theorem highlights how, in some voting scenarios, the preferences of voters can lead to outcomes that are highly sensitive to even small changes in the voters' preferences or the rules of the voting system itself. Specifically, it deals with the idea of non-transitive preferences in a multidimensional policy space where voters have different ideal points.
