We cover some of this material in 2301 when we discuss the formation of public opinion and how people process media information, so there's nothing new in this story pointing out that we can be made to believe propaganda except additional evidence about how it can happen:
In recent years, dozens of psychological studies have shown that we shape incoming information as much as it shapes us. We sift and sort, choosing what we like and discarding what we don't. Much of this happens unconsciously in what I call the hidden brain. We see the effects of these mental gymnastics all the time: Few people change their minds on hot-button issues, even when new information is provided to them. Political commentators generate lots of heat, but when was the last time you heard about a liberal who was persuaded by Rush Limbaugh? Or a conservative who switched parties after watching a Michael Moore movie? The partisan divide in the country has barely budged for over a decade—hardly what you'd expect if the hyper-partisan information we see all around us was having much effect.
