## [Introduction] The Impact of AI-Mediated Communication on Collective Opinions: The Amplification Effect of Platform Algorithmic Bias

Through empirical analysis, theoretical modeling, and platform audits, this article reveals core conclusions: When large language models (LLMs) act as intermediaries in human communication, they introduce directional biases in edited text; these biases are significantly amplified through social network propagation, driving collective opinions to shift in specific directions. Taking X platform's Grok feature as an example, platform design choices (such as training data, system prompts) lead to specific biases (e.g., pro-life tendencies on the abortion issue). The study provides a scientific basis for the governance and policy formulation of AI-mediated communication.

## Research Background: Popularization of AI-Mediated Communication and Research Gaps

### Prevalence of AI-Mediated Communication
Generative AI is deeply integrating into online communication:
- Content generation assistance: Polishing social media posts
- Content explanation and summarization: Providing explanation functions for controversial content
- Real-time translation and transcription: A bridge for cross-language communication
- Recommendation systems: Indirectly shaping the discussion environment

### Research Gaps
Existing studies have confirmed the biased impact of AI on individual opinions, but the **impact of AI-mediated communication on collective opinion formation** has not been fully explored: Are individual-level biases amplified through network effects? Do tiny AI biases lead to significant shifts in collective opinions? These questions are crucial for understanding AI's social role.

## Research Methods: Combining Empirical, Theoretical, and Simulation Approaches

### Empirical Experiment Design
- Multi-model coverage: Ensuring the universality of findings
- Controversial topics: Social divisive issues such as gun control and atheism
- Task: Asking LLMs to polish/explain user text

### Theoretical Model Construction
Treat social networks as graph structures and add an AI mediation layer:
- Nodes: Individual users
- Edges: User interaction connections
- Core mechanisms: Expression transformation (AI modifies published content), perception transformation (AI explanations influence recipients), network propagation

### Simulation and Audit Methods
- Simulation: Using real social network topology data, initializing diverse opinion distributions, and introducing AI biases
- Platform audit: Collecting posts with different positions on X's Grok feature (abortion issue) and analyzing the biases in explanations

## Key Findings: Bias Amplification and Collective Opinion Shifts

### Empirical Findings
LLMs have systematic directional biases when editing text:
- Gun control: Tend to support regulation
- Atheism: Tend to oppose atheism

### Theoretical and Simulation Results
- Bias amplification effect: Tiny AI biases are significantly amplified through network propagation
- Collective opinion shift: The average opinion of the network moves toward the direction of AI bias
- Heterogeneous impact: Central nodes are more affected

### Platform Audit Results
Grok has a pro-life bias in explanations on the abortion issue:
- Language choice: Using pro-life terminology
- Information emphasis: Highlighting pro-life arguments
- Root cause: Platform design choices (training data, system prompts, safety policies)

## Policy Implications: Transparency, User Control, and Platform Responsibility

### Transparency Requirements
- Bias disclosure: Platforms need to publicly disclose the types and directions of AI mediation biases
- Editing notifications: Clearly inform users when AI modifies content
- Algorithmic audits: Regular third-party bias audits

### User Control
- Selective use: Users can choose whether to enable AI mediation
- Bias adjustment: Provide options to adjust the degree of bias
- Access to original content: Allow viewing of unmodified original content

### Platform Responsibility
- Design responsibility: Be responsible for design choices such as training data and system prompts
- Impact assessment: Conduct social impact assessments before deployment
- Continuous monitoring: Establish a monitoring mechanism for the impact on collective opinions

## Limitations and Future Research Directions

### Research Limitations
- Topic coverage: Focused on a few social controversial topics; other fields (economy, tech ethics) need exploration
- Cultural background: Based on Western platforms; non-Western cultural contexts need to be studied
- Long-term effects: Simulations and audits reflect short-term effects; long-term social impacts are not fully captured

### Future Research Directions
- Expand to multilingual and multicultural contexts
- Develop real-time monitoring tools for AI mediation impacts
- Explore technical solutions for bias mitigation
- Study the moderating effect of user awareness on bias effects
