Is giving up the independence of irrelevant alternatives that bad?
- dredmorbius 15y agoIt's not that irrelevant alternatives are improperly ranked. It's that introducing irrelevant alternatives changes the ranking of relevant alternatives: http://en.wikipedia.org/wiki/Independence_of_irrelevant_alternatives http://en.wikipedia.org/wiki/Independence_of_irrelevant_alte... E.g.: in an election between La Roge and Grebe Sough, if Handle Parr's decision to run changes the outcome between Roge and Sough, you have a dependence on an irrelevant alternative.
