Chauncey Devega: "In psychiatry there is a condition known as folie à deux, which describes how two people share a psychosis. This almost never happens. It is very rare. But on a massive societal level this is when there is a delusion that millions of people share. This delusion becomes its own reality. The people imbibe it and then reinforce this alternate reality among each other.

In Rwanda, how did genocide suddenly occur among people who the other day had been previously living in peace? A shared mass delusion. In the United States we are discovering that reality is more fungible and easier to manipulate than most of us realized. With Fox News and Donald Trump, it is possible to create a nightmare fantasy and make it real."
