Co-Writing with Opinionated Language Models Affects Users’ Views

Paper Information

• Subject Area: Human-Computer Interaction and the Impact of AI Language Models on Social Opinions
• Keywords: AI Language Models, GPT-3, Social Influence, Technological Risks, Collaborative Writing, Opinion Change

Research Background and Problem

• Problem or Challenge:

  • With the widespread application of large language models (e.g., GPT-3) in daily communication, they may have a potential impact on users' opinions. However, the specific scale and process of this influence remain unclear.
  • The research focuses on how these models influence users' writing content and attitudes through collaborative writing tools.

• Significance:

  • The proliferation of language models may have profound social implications, influencing not only users' behaviors but also their opinions and attitudes.
  • Understanding these impacts is crucial for developing relevant technological regulations and preventing potential societal risks.

• Research Motivation and Related Work:

  • Traditional social influence research has revealed that individuals may change their behaviors and attitudes under group pressure, while the development of AI technology has introduced new forms of influence.
  • Current research on language models primarily focuses on risks such as bias, misinformation, and the transmission of cultural values, with limited exploration of their potential impact on social opinions on public issues.
  • Preliminary studies suggest that language model suggestions may influence users' written expressions, but their effect on users' overall attitudes toward social issues remains an unresolved question.

Solution

• Methods and Experimental Design:

  • The authors designed an online experiment where participants completed a debate writing task on the topic "Is social media beneficial to society?" using three experimental conditions:
    1. Control Group: No language model assistance;
    2. Tech-Optimistic Group: Using a language model configured to support the view that "social media is beneficial to society";
    3. Tech-Pessimistic Group: Using a language model configured to support the view that "social media is harmful to society."
  • The GPT-3 model was used to generate biased opinionated text through customized prompt engineering. The model's suggestions were presented to users in real-time.

• Innovative Points:

  • Introduced the concept of "latent persuasion," which refers to the process by which AI language models influence users' expressions and attitudes through collaborative writing.
  • Compared the influence of model biases across different experimental groups, revealing potential pathways for opinion transmission (informational influence, behavioral influence, normative influence).

• Implementation Steps:

  1. Create a simulated social media platform interface to provide the experimental environment.
  2. Configure the GPT-3 model to generate text suggestions biased toward specific viewpoints.
  3. Collect experimental data, including participants' written content, usage of model suggestions, and subsequent attitude survey responses.

Research Findings

• Specific Results:

  • Participants using opinionated language models were more likely to support the model's biased viewpoints in their writing.
  • Users in the experimental groups showed significant changes in their attitudes toward social media in the follow-up survey, indicating that language models influence not only written expression but also overall attitudes.

• Advantages Compared to Existing Solutions:

  • This study opens a new research direction on the potential societal impacts of language models. Unlike studies that focus solely on language generation quality or creative support, this research examines how language model behavior influences users' thoughts.
  • Provided quantitative measurements and logistic regression analysis to ensure the reliability of statistical results.

• Experimental or Evaluation Results:

  • Participants using the model configured to support "social media is beneficial to society" were twice as likely to express support for this viewpoint compared to the control group.
  • In shorter writing tasks, users were more susceptible to language model suggestions. However, even in longer tasks, the model's bias significantly influenced users' expressions.

• Limitations and Future Directions:

  • Limitations:
    • The experiment involved only one topic, which cannot fully encompass the impact of language generation technology on other areas (e.g., politics, environmental issues).
    • The GPT-3 model used was limited to a single configuration, without exploring the effects of other configurations or model architectures on opinion transmission.
  • Future Directions:
    • Expand research to more diverse discussion topics and examine the long-term effects of language model influence.
    • Investigate the role of user characteristics (e.g., education level or political orientation) in opinion formation.
    • Develop tools to monitor embedded opinions in language models and explore how to adjust opinion generation to avoid bias.

Discussion and Societal Impact

• Theoretical Significance:

  • Proposed that the persuasion pathways of language models may include informational influence, normative influence, and behavioral influence that indirectly changes opinions by altering user behavior.
  • Further emphasized the need to control embedded opinions when designing language models.

• Practical Applications and Risks:

  • Could be applied in a wide range of technologies, such as social media interactions, smart replies, and predictive keyboards.
  • Caution is needed to prevent language models from being misused for commercial or political purposes to influence public opinion.

• Ethical Considerations and Call to Action:

  • The authors emphasized the importance of transparency and advocated for public discussions and policy regulations to prevent the potential risks of language model persuasion.
  • Future research should support product teams and policymakers in developing safer AI technology development pathways.
