The uncommon-ground algorithm assigns a bridging bonus. If you plot people with k-means clustering in semantic space, the smaller rural group still forms a coherent cluster. The more you can bridge, the more bonus you get for going viral. That means the so-called mainstream — once both sides of urban drivers can agree — has to reach out to the rural segment in order to gain virality. We already say that if an idea does not get cross-group validation of more than 75 percent, we do not consider it in the next agenda round. Again, it changes the incentive. You have to reach out to the other cluster. That is how Community Notes work in modern social media.
