From a pedant:
Prof. Ken Arrow, https://en.wikipedia.org/wiki/Kenneth_Arrow a Nobel Prize winning economist and a Polymath proposed Arrows Impossibility theorem. From the wikipedia page: (bold faced by me). https://en.wikipedia.org/wiki/Arrow's_impossibility_theorem under Interpretation:

Although Arrow's theorem is a mathematical result, it is often expressed in a non-mathematical way with a statement such as no voting method is fair, every ranked voting method is flawed, or the only voting method that isn't flawed is a dictatorship.[11] These statements are simplifications of Arrow's result which are not universally considered to be true. What Arrow's theorem does state is that a deterministic preferential voting mechanism—that is, one where a preference order is the only information in a vote, and any possible set of votes gives a unique result—cannot comply with all of the conditions given above simultaneously.
