Propaganda is a way for a higher up and or government to control civilians in secretive ways. Propaganda appears through 1984 numerous times. we first see propaganda as soon as one would start reading. it is mentioned in the novel that big brother and ingsoc have telescreens in every room and outside. there are also posters littered through out the whole of Oceana. big brother also displays messages on the telescreens in a confusing way so that all of the civilians will listen and not disobey him. big brother also sends steamers (bombs) to the proles to instill fear in them. big brother has a thing called thought police who stroll around the city and make sure that no one is showing too much emotion making sure no one uses old speak and especially that no one is thinking of their pasts or of a way to stop big brother.
there are multiple propaganda techniques some that show up in 1984 are, cause and effect mismatch and stereotyping. firstly we have cause and effect mismatch which is to confuse your audience about what is really happening which we can see numerous times in 1984 with big brother and how he tries to confuse his follows to make sure that they do not catch on to what is actually happening. secondly we have stereotyping which is giving some one a bad label by using an easy to remember name we see this in 1984 because the lowest class of Oceana are called proles and no one really thinks to talk to them or even go to their part of the city
