Quadratic voting

Quadratic voting is a way for groups to make decisions in a fair way. It uses a form of voting called a "quadratic vote." In this type of voting, each person gets a certain number of votes to use. It's called "quadratic" because each vote has a cost: the more votes you have, the more each vote costs. So for example, if a person has 5 votes, the first vote costs one point, the second vote costs four points, the third vote costs nine points, and so on. This way, it takes more points to have a bigger impact on the final decision, so everyone's opinion is heard, but people who care the most get their way the most.
