Routes of Persuasion02:20

Routes of Persuasion

64.1K
Persuasion is the process of changing our attitude toward something based on some kind of communication. Much of the persuasion we experience comes from outside forces. How do people convince others to change their attitudes, beliefs, and behaviors? What communications do you receive that attempt to persuade you to change your attitudes, beliefs, and behaviors?

The Anchoring-and-Adjustment Heuristic

7.2K
In order to make good decisions, we use our knowledge and our reasoning. Often, this knowledge and reasoning is sound and solid. However, sometimes, we are swayed by biases or by others manipulating a situation. For example, let’s say you and three friends wanted to rent a house and had a combined target budget of $1,600. The realtor shows you only very run-down houses for $1,600 and then shows you a very nice house for $2,000. Might you ask each person to pay more in rent to get the...

While variables are sometimes correlated because one does cause the other, it could also be that some other factor, a confounding variable, is actually causing the systematic movement in our variables of interest. For instance, as sales in ice cream increase, so does the overall rate of crime. Is it possible that indulging in your favorite flavor of ice cream could send you on a crime spree? Or, after committing crime do you think you might decide to treat yourself to a cone?

Confirmation Biases

5.5K
The confirmation bias is the tendency to focus on information that confirms our existing beliefs and ignore information that is inconsistent with our expectations. For example, if you think that your professor is not very nice, you notice all of the instances of rude behavior exhibited by the professor while ignoring the countless pleasant interactions he is involved in on a daily basis. Have you ever fallen prey to the confirmation bias, either as the source or target of such bias?

Stereotypes, Prejudice, and Discrimination

90.2K
Humans are very diverse and although we share many similarities, we also have many differences. The social groups we belong to help form our identities (Tajfel, 1974). These differences may be difficult for some people to reconcile, which may lead to prejudice toward people who are different. Prejudice is a negative attitude and feeling toward an individual based solely on one’s membership in a particular social group (Allport, 1954; Brown, 2010). Prejudice is common against people who...

Framing Effects

7.4K
Information is everywhere and its presentation—such as how and when items are presented—can impact our perceptions and decisions surrounding the info. This broad concept umbrellas framing effects—influences that occur due to the way information is framed in its appearance, whether it’s purely the order or the specific wording of a message. Let’s take a look at numerous ways in which two versions of something can objectively say the same thing, yet we respond in...

Summary

Linguistic vagueness, when pragmatically marked, acts as a persuasive strategy by reducing cognitive effort. This implicit technique bypasses deep interpretation, making persuasive messages more easily accepted.

Area of Science:

  • Linguistics
  • Psycholinguistics
  • Cognitive Science

Background:

  • Linguistic vagueness is often employed in persuasive communication.
  • Its precise function and cognitive processing remain underexplored.

Purpose of the Study:

  • To define and explore pragmatically marked vagueness.
  • To investigate the psycholinguistic processing of vague language.
  • To validate its use as an implicit persuasive strategy.

Main Methods:

  • Definition of pragmatically marked vagueness.
  • Analysis of vague expressions in advertising and political texts.
  • Self-paced reading task experiment.

Main Results:

  • Markedly vague expressions were read faster than precise ones.
  • This suggests shallow processing without retrieval of exact referents.
  • Distinction between context-supported and non-supported vague expressions validated.

Conclusions:

  • Pragmatically marked vagueness functions as an implicit persuasive strategy.
  • It reduces cognitive load and epistemic vigilance.
  • Supports shallow processing of persuasive messages.
