Another reason to bookmark the article is the reference, at the end, to other mechanisms that intentionally try to identify polarization, and favor things that bridge across divides rather than perpetuate them : (i) pairwise quadratic funding, which is being used in Gitcoin Grants and (ii) Polis, a discussion tool that uses clustering algorithms to help communities identify statements that are commonly well-received across people who normally have different viewpoints. As mentioned in the article, more academic work in the field would be helpful.
