It's easy to choose a side when lots of information on a subject you care about is tossed at you. Sometimes it's true, it may even be false, but regardless, propaganda to push an issue both positively and negatively is everywhere. During World War I, the use of propaganda emerged along with the rise of modern media outlets. Propaganda -- spreading ideas, information or rumors for a political purpose -- was refined into an art.
In 1937, Edward Filene helped establish the Institute of Propaganda Analysis. The goal of this institution was to help educate the American public and to understand the techniques by which propaganda is spread. Filene and his fellow researchers identified seven techniques used by propagandists.
Using negative or discriminatory words, propagandists arouse suspicion and prejudice. The goal is to create an overall dislike of a group of people, so verbally attacking their beliefs, institutions, leaders or religion is fair game. Name calling is often used in ridiculing cartoons or writing.
Using slogans or simple catchphrases, propagandists make generalized statements attractive to their audience. Usually these statements involve ideas of love, honor, glory, peace, family values, freedom, patriotism -- anything general enough to inspire pride. These statements usually say very little, so they cannot be proved or disproved.
A transfer associates a revered symbol with an idea the propagandist wants to promote. If an idea can be linked with, say, a flag, it has a greater chance of winning popular approval. The stir of emotions makes it difficult for people to clear their minds and think critically.
A testimonial makes an association between a respected or authoritative person and the cause. The hope is that the respected person will lead others to follow his ideas. It is similar to a celebrity endorsement of a product.
The goal of this technique is to convince the audience that the spokesman is like them and shares their woes and concerns. Using plain language and mannerisms, he is able to build trust by his followers.
This technique capitalizes on the human drive to be part of a crowd, a member of the winning team. By creating the illusion that widespread support exists, the propagandist hopes those who are on the fence will join the cause. If they refuse, this technique seeks to make them feel isolated.
By using only those facts that support their ideas, propagandists can make it seem that their way is the only correct way. The aim of card stacking is for the audience to assume these facts are conclusive. By "stacking cards against the truth," propagandists can control the beliefs of their audience.
