This study is suspect because it does not reference propaganda history or research. It does not even use the word. Also the mechanism of defining truth is suspect: it is always possible to find several sources that agree on something and several others that disagree. There seems not much emphasis on primary sources.

Please research the history of propaganda in the United States for yourself. See articles on Edward Bernays and documentaries like The Century of the Self. Research terms like "the fourth estate".
