Quadratic Voting: Distributing Voting Power Based on Acoustic Interference

"Quadratic voting is a special application of aggressive proportionality," says Lionel Penrose. It's important to give votes based on correlations and down weight correlated signals instead of giving votes in proportion to power. This concept was used in European treaties to determine voting weights based on population. Quadratic voting applies this notion to individuals with different preferences. The quadratic rule has a statistical explanation related to acoustics, where uncorrelated signals cancel each other out, but correlated signals grow stronger. This metaphor can be applied to ensure fair distribution of voices. Quadratic voting and country applications are just special cases of a broader rule that focuses on coordination and correlation."
