The independence of irrelevant alternatives principle states that the ranking between any two outcomes A and B should not be affected by whether some third outcome C is also available. In other words, if A beats B in a head-to-head comparison, then A should still beat B even if a third option is added that has no chance of winning, or that no one prefers. This principle is important in ensuring that the outcome of a vote accurately reflects the preferences of the voters.
