Which voting system is the best? - Alex Gendler

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.

One thing not mentioned in this video is that plurality voting also "incentifizes lying about your preferences" not just multiple rounds. This happens (kind of) in the US, where people might want to vote for a third party (ex. green party, libertarian party, etc.) might end up voting for the democratic/republican candidate because they think that the third party they support is unlikely to win.

I actually took a whole class centered around the mathematics surrounding politics. We spent weeks just on voting systems

[christodang]

All too often we laud "popular vote" as a majority system when in reality it's most often a plurality in most countries and this video very well illustrates how that system can be flawed and other systems in comparison. Kudos!

I'd choose North no matter where I'd live, it being centermost.

I live in Switzerland and most people love how the president is chosen. We vote for the party we want and then the party’s with the most votes can get on to seven on the seven seats available. No one has more than 2). Then all 7 elected have the same power and collaborate. They are each president for one year but have no additional power.
