How do you prevent fake science? This article tells us why its bad for the state to manage information flow. But Facebook and the alt reality around Trump show us that society is not smart enough to separate reality from fiction. I suspect in a city full of developers we could make science work. In a city with half the people are below 100 IQ, I am not sure the end result will be great. So many ways it can go bad.
