Quadratic Voting

Quadratic voting is a voting system designed to allow voters to express their preferences more accurately and to align the outcomes of voting more closely with the preferences of the voters. It is based on the idea that voters should be able to express their preferences more strongly for issues that are more important to them.

In a quadratic voting system, each voter is given a certain number of votes that they can use to express their preferences. These votes can be used in any combination, but the cost of using each vote increases quadratically. For example, if a voter has 10 votes and wants to express a strong preference for an issue, they could use 4 votes for that issue, which would cost them 4 * 4 = 16 votes in total. If they wanted to express an even stronger preference, they could use 8 votes for the issue, which would cost them 8 * 8 = 64 votes in total. The quadratic voting system is intended to encourage voters to be more strategic in how they use their votes and to better reflect the intensity of their preferences. It has been suggested as a possible alternative to traditional voting systems, such as first-past-the-post or ranked choice voting, in order to better align the outcomes of elections with the preferences of voters.
