Wylie’s new book, Mindf*ck, explains how Cambridge Analytica harvested the information of tens of millions of Facebook users, then used the data to target people susceptible to disinformation, racist thinking and conspiracy theories. 

…[Bannon] followed this notion of the Breitbart doctrine, which is that politics exists downstream from culture. So don’t just focus on the day-to-day politics. Try to actually make an impact on an enduring change in culture, because politics will just flow from that.

…If you can understand how a person thinks and feels and engages in the world, and what kinds of biases they have, you can then figure out what’s going to be most effective at engaging them in a particular objective

…What we were looking at is how to use data online to identify people who would be likely targets of different extremist groups. And from that, try to understand and unpack: How would a fairly extreme ideological message spread through different kinds of social networks? 

……”They targeted people who were more prone to conspiratorial thinking,” Wylie says. “They used that data, and they used social media more broadly, to first identify those people, and then engage those people, and really begin to craft what, in my view, was an insurgency in the United States.”
