Summary
Generative artificial intelligence (AI) can aid political persuasion research. AI-generated messages shift attitudes, but customization and interaction offer minimal advantages over generic content.
Area of Science:
- Political Science
- Psychology
- Artificial Intelligence
Background:
- Political persuasion research faces data limitations hindering understanding of social and psychological processes.
- Generative large language models (LLGs) offer novel solutions to overcome data constraints in persuasion studies.
Purpose of the Study:
- To investigate the efficacy of generative AI in political persuasion research.
- To evaluate AI-generated persuasive strategies, including message customization and elaboration, on attitude change and vote support.
Main Methods:
- Two preregistered online survey experiments were conducted.
- Four types of AI-generated counterattitudinal persuasive messages were tested.
- Message customization (based on personal traits) and elaboration (through interaction) were examined.
Main Results:
- All AI-generated persuasive strategies significantly changed attitudes and vote support compared to a control group.
- Message customization and AI interaction did not yield substantially greater persuasion than a generic message.
- Persuasive messages moderated attitudes but had limited impact on democratic reciprocity and affective polarization.
Conclusions:
- Generative AI is a viable tool for studying political persuasion, offering insights into psychological and communicative processes.
- The effectiveness of AI-driven persuasion is not significantly enhanced by message customization or interactive elaboration.
- Attitude moderation does not automatically translate to increased democratic tolerance or reduced affective polarization.

Routes of Persuasion

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?

Stereotypes, Prejudice, and Discrimination
89.7K
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...

Persuasion Strategies

Researchers have tested many persuasion strategies, including the foot-in-the door and the door-in-the-face techniques, in a variety of contexts. Ultimately, the principles are effective in selling products and changing people’s attitude, ideas, and behaviors (Cialdini & Goldstein, 2004).

Stereotype Content Model
13.9K
The Stereotype Content Model (SCM) was first proposed by Susan Fiske and her colleagues (Fiske, Cuddy, Glick & Xu, 2002; see also Fiske, 2012 and Fiske, 2017). The SCM specifies that when someone encounters a new group, they will stereotype them based on two metrics: warmth—or that group’s perceived intent, and how likely they are to provide help or inflict harm—and competence—or their ability to carry out that objective. Depending on the warmth-competence...

Confirmation Biases
5.4K
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?
