This often occurs in negative advertisements and comparative advertisements—both for products and political causes. An example would be a manufacturer of a product displaying an ad that refutes one particular claim made about a rival's product, so that when the audience sees an ad for said rival product, they refute the product claims automatically. Narrative transportation theory Narrative transportation theory proposes that when people lose themselves in a story, their attitudes and intentions change to reflect that story. The mental state of narrative transportation can explain the persuasive effect of stories on people, who may experience narrative transportation when certain contextual and personal preconditions are met, as Green and Brock postulate for the transportation-imagery model. Narrative transportation occurs whenever the story receiver experiences a feeling of entering a world evoked by the narrative because of empathy for the story characters and imagination of the story plot. Social judgment theory Social judgment theory suggests that when people are presented with an idea or any kind of persuasive proposal, their natural reaction is to immediately seek a way to sort the information subconsciously and react to it. We evaluate the information and compare it with the attitude we already have, which is called the initial attitude or anchor point. When trying to sort incoming persuasive information, an audience evaluates whether it lands in their latitude of acceptance, latitude of non-commitment or indifference, or the latitude of rejection. The size of these latitudes varies from topic to topic. Our "ego-involvement" generally plays one of the largest roles in determining the size of these latitudes. When a topic is closely connected to how we define and perceive ourselves, or deals with anything we care passionately about, our latitudes of acceptance and non-commitment are likely to be much smaller and our attitude of rejection much larger. A person's anchor point is considered to be the center of their latitude of acceptance, the position that is most acceptable to them. An audience is likely to distort incoming information to fit into their unique latitudes. If something falls within the latitude of acceptance, the subject tends to assimilate the information and consider it closer to his anchor point than it really is. Inversely, if something falls within the latitude of rejection, the subject tends to contrast the information and convince themself the information is farther away from their anchor point than it really is.
