Tang has sponsored the use of software called Polis, invented in Seattle. This is a platform that lets people make tweet-like, 140-character statements, and lets others vote on them. There is no “reply” function, and thus no trolling or personal attacks. As statements are made, the system identifies those that generate the most agreement among different groups. Instead of favoring outrageous or shocking views, the Polis algorithm highlights consensus. Polis is often used to produce recommendations for government action.
