It’s been awhile since I read it, but I think Herst’s conclusion for that chapter was that, the best he could personally do was get them to learn how to shape the message, but he was never able to truly disabuse them of the notion that what they believed and what they had been told was shaped in exactly the same way, if not more egregiously false, which he believed would eventually be catastrophic for the U.S. down the line. Never believe your own bullshit.
