 But notice that a bigger community is more likely to find the truth too. Why? Because bigger, less connected networks are better insulated against misleading results. Some doctors are bound to get data that don’t reflect the true character of the new treatment once in a while. And when that happens, their misleading results risk polluting the community with misinformation, discouraging others from experimenting with the new treatment. But the more people in the network, the more likely the misleading results will be swamped by accurate, representative results from others. And the fewer people see the misleading results, the fewer people will be misled.
