Dive into four different voting systems: plurality, instant runoff, tactical, and the Condorcet method, and find out which is fairest. -- Imagine we want to build a new space port at one of four recently settled Martian bases, and are holding a vote to choose its location. Of the 100 colonists on Mars, 42 live on West Base, 26 on North Base, 15 on South Base, and 17 on East Base. Assuming that everyone wants the port to be closest to their home base, what is the fairest way to conduct the vote? Alex Gendler digs into voting systems.
