Can AI Chatbots Improve Online Political Discourse?

1. Introduction

Political discourse is the lifeblood of democracy now much of it manifests as online political discourse. Open and inclusive conversations enable diverse groups to come together peacefully, understand opposing perspectives, identify shared problems, and find compromise solutions.

Historically, these conversations occurred through face-to-face discussions and community forums. However, there has been a massive shift in political conversations in recent decades to online spaces like social media, discussion boards, and messaging platforms. While the scale of these digital conversations enables many more voices to engage in debate, it also poses new challenges.

Online political talk is plagued by misunderstanding, unproductivity, and conflict. Nearly half of social media users report seeing cruel behavior towards others with different political opinions. Many people avoid political topics online to steer clear of uncivil disagreements. Those who engage often find themselves trapped in corrosive arguments rather than constructive dialogue.

This hostile climate undermines the inclusive deliberation crucial for a healthy democracy. It reduces opportunities for mutual understanding and erodes social cohesion. Citizens disengage from democratic participation rather than having difficult but democratic conversations across lines of difference.

Many scholars argue that improving the quality of online political talk is an urgent priority. However, doing so at the massive scale of digital spaces poses daunting challenges. Most interventions are time and labor-intensive, requiring trained moderators to facilitate small group conversations.

Advances in artificial intelligence may provide tools to help meet this challenge. Large language models like GPT-3 point to the potential for AI systems to participate constructively in nuanced social domains like political deliberation. Researchers conducted an online randomized controlled trial with over 1,500 participants matched for text-based chats. The large language model GPT-3 powered the assistant and made real-time suggestions to rephrase messages using techniques like restating and validating.

Political science researchers Argyle et al. conducted an online experiment to test if an AI chat assistant could improve online political discourse. If carefully designed and deployed, could AI help improve online conversations without manipulating or polarizing them? This article explores that question, examining whether AI systems might facilitate more productive online political discourse.

2. Democratic Discourse and the Problem of Online Political Conversations

Open and inclusive democratic discourse is vital for diverse societies to maintain social cohesion and address shared problems.

2.1 The Vital Role of Democratic Discourse

Political theorists emphasize that bringing people together in discussion enables compromise and coalition-building. Even when conversations do not resolve conflicts, the simple act of listening across divides fosters mutual understanding. Citizens who feel heard by political opponents are more likely to grant the legitimacy of different views.

Historically, these democratic conversations occurred through face-to-face community meetings, debate societies, and interpersonal discussions. The intimacy of in-person talks created space for nuanced dialogue on complex issues.

2.2 The Shift to Online Conversations

In recent decades, however, political talk has rapidly migrated online. Social media platforms host over 100 billion daily messages. Messaging apps see 7 billion daily conversations.

This offers tremendous opportunity for inclusive democratic deliberation at scale. More citizens can make their voices heard and engage in debate. However, it also poses new risks.

Online political talk often breeds more incivility and conflict than connection. Nearly half of users report cruel behavior and harassment targeting those with opposing views. The relative anonymity of online spaces may encourage demonization over understanding.

2.3 The Need for Interventions

These dynamics erode social cohesion and undermine inclusive democratic deliberation. Many citizens avoid politics online, while others find themselves trapped in unproductive arguments.

Scholars argue that improving the quality of online discourse is an urgent need. But doing so at the massive scale of digital spaces poses steep challenges. Most moderation approaches require intensive effort that cannot easily scale.

The rapid growth of online political talk calls for similarly scalable solutions. Could AI tools provide an answer? The following chapter explores that potential.

3. Using AI Tools to Facilitate High-Quality Democratic Discourse

Advances in artificial intelligence open intriguing possibilities for improving online political conversations at scale. While rightly concerned about potential harms, many experts argue AI systems could facilitate more constructive dialogue if carefully designed.

3.1 AI’s Potential for Social Science

AI tools like large language models (LLMs) are increasingly applied to complex social domains. LLMs like GPT-3 showcase an ability to generate remarkably human-like text across a variety of styles and viewpoints.

This artful expressiveness enables more nuanced applications for social science. Rather than replace human roles, AI could participate constructively in spaces like political discourse. The key is mindful and ethical implementation.

3.2 Strategies for Improving Conversations

Scholars identify techniques to improve interpersonal conversations: restating points to affirm understanding, using polite language, and validating different views’ legitimacy.

However, teaching these skills requires intensive effort from trained moderators. The challenge is scaling such interventions to massive online conversations.

3.3 An AI Assistant to Improve Conversations

We explore whether AI chat tools could provide scalable assistance. An AI assistant could monitor conversations and make personalized suggestions to rephrase messages using proven techniques.

This would provide real-time, in-context guidance at scale, like having a moderator for every online chat. But it would maintain human agency – users could ignore or modify suggestions.

Could this facilitate more constructive political discourse online? The next chapter examines this question through an experimental study.

4. Methods and Results of a Field Experiment

Political science researchers conducted an online experiment to test if an AI chat assistant could improve political conversations. Participants with opposing views on gun regulation had text-based chats. They randomly assigned an AI tool to suggest rephrasings to some participants.

4.1 Study Design

The AI assistant aimed to increase perceptions of feeling understood using proven techniques like restating points and validating the legitimacy of different views. It made personalized suggestions to rephrase messages in real-time during conversations.

The study recruited proponents and opponents of gun regulation in the U.S. After a survey, they were matched for online chats. In treated chats, one participant received AI suggestions; their partner did not. After the chat, all participants reported on conversation quality, democratic reciprocity, and policy views. This lets them measure the AI’s impact.

This study utilized pre-post survey designs to assess outcomes like conversation quality and democratic reciprocity. Argyle et al. had participants complete surveys before and after engaging in online political chats, allowing measurement of changes in outcomes like feeling respected and understood (conversation quality). The design also compared treatment groups with an AI assistant to controls, enabling analysis of how the AI impacted democratic reciprocity.

Pre-post surveys involve participants completing questionnaires before and after an intervention or experience. This allows researchers to measure changes in outcomes of interest from baseline to post-intervention. For instance, Argyle et al. used pre-post surveys around online chats to assess changes in conversation quality and democratic reciprocity.

Valid pre-post survey design requires careful construction of survey instruments to ensure they accurately measure the intended constructs. For example, the post-chat surveys in the Argyle et al. study used multiple questions to create scales assessing conversation quality (feeling respected and understood) and democratic reciprocity (respect for opponents’ views).

The politeness analysis and topic clustering analysis provided important validity evidence that the AI chat assistant was functioning as intended in the study:

Politeness Analysis

• Compared original messages to AI-suggested rephrasings chosen by users on measures like positive emotion, hedges, and acknowledgment.
• Found rephrased messages scored higher on politeness/validation features, indicating the AI suggestions successfully changed the tone to be more polite/validating.

Topic Clustering Analysis

• Used NLP techniques to cluster all chat messages into topics based on semantic similarity.
• Compared distribution of original messages and AI-rephrased messages.
• Both messages were evenly distributed across the topic space, indicating rephrasings did not fundamentally alter the content.

Together, these analyses proved that the AI assistant successfully changed the tone of messages to be more polite/validating without changing the topic or content. This validates that the intervention functioned as intended – improving politeness and perception of being understood without manipulating content or attitudes.

The analyses address concerns about biases or improper functioning of AI systems. Showing the AI worked “as advertised” to change the tone. Still, no topic provides valid evidence that increases confidence in attributing the observed study outcomes to the theorized mechanisms of feeling respected/understood. The analyses help rule out alternative explanations, strengthening the claim that improved democratic reciprocity was due to increased politeness/validation rather than topic changes.

4.2 Results

The AI rephrasings increased participants’ conversation quality and willingness to grant opponents legitimacy. Effects were most substantial for partners of treated participants. This suggests that AI increased perceptions of feeling understood without fundamentally altering conversation content. Participants maintained their original policy positions.

• Participants chose to use the AI-suggested rephrasings around two-thirds of the time (1,798 out of 2,742).
• When the AI suggestions were used, they were evenly split between the three types of interventions: restating the user’s point (30%), validating the legitimacy of different views (30%), and increasing politeness (40%).
• The even split shows the AI made suggestions from all three evidence-based techniques for improving conversations equally frequently.
• The high rate of choosing the AI suggestions (66%) indicates users found them useful for rephrasing their messages.
• The fact that rephrasings were not chosen every time maintains user agency and control over message content.
• Overall, the patterns show the AI assistant was broadly viewed as helpful by participants for improving tone while respecting users’ ability to accept, modify, or reject suggestions.
• This further confirms that the AI worked as intended to change tone but not control content or attitudes.

The high acceptance rate and balanced split between intervention types demonstrate the AI assistant successfully provided politeness, validation, and restating suggestions that users viewed as valuable additions to their messages.

The study analyzed the effect of the AI chat assistant intervention based on the “dosage” or number of rephrasing suggestions participants received. Here are some critical points on the dosage analysis:

• Conversations were designed to continue until one participant received four rephrasing prompts from the AI assistant.
• In practice, many conversations ended earlier, so participants got varying “doses” of the intervention.
• The analysis divided participants into subgroups based on the number of interventions received: 0, 1, 2, 3, or 4 rephrasings.
• Comparing treatment effects across these subgroups showed a pattern of more significant impacts for those receiving more interventions.
• For democratic reciprocity, the effect size grew from 2.5 points after one rephrasing to 6 points after the full four rephrasing.
• This dosage-response relationship strengthens the evidence that the AI assistant drove the observed effects.
• More interventions likely gave the AI more opportunities to improve the conversation tone and perception of being understood.
• The pattern aligns with the idea of a “dose-response” relationship commonly seen in medicine and social science interventions.
• It suggests that even more significant impacts might occur with continued exposure beyond the four rephrasings tested here.

In summary, the analysis by intervention dosage further validated the AI assistant’s effects and showed that more rephrasing suggestions lead to more significant improvements in democratic reciprocity. This strengthens the case for the AI as the driver of impact.

Comparing changes from pre to post-test between treatment and control groups enables causal claims about intervention effects. The pre-post design used by Argyle et al. found significant increases in conversation quality and democratic reciprocity when one chat participant had an AI assistant, compared to control chats.

While pre-post surveys are expected in deliberation research, Argyle et al.’s conception of “conversation quality” differed from typical group-based deliberation studies. They focused on individual perceptions of feeling respected and understood rather than group dynamics or reaching an agreement.

In sum, this experimental study provides initial evidence that AI tools could improve online political discourse when thoughtfully implemented. The final chapters discuss implications.

5. Discussion and Implications

The experimental results provide initial evidence that AI tools can improve online political conversations when carefully implemented. But what are the broader implications?

Significantly, the AI assistant increased quality and reciprocity without manipulating participants’ views. This suggests AI’s participation need not be polarizing if thoughtfully designed.

The more substantial effects for partners also highlight the importance of feeling understood. Even without changing attitudes, conversations improved when the AI increased perceived acknowledgment.

The study’s follow-up analysis three months after the initial experiment found no evidence that the effects of the AI chat assistant persisted long-term. Here are some key points about this:

• After the initial experiment, researchers re-contacted participants to explore whether the effects on conversation quality and democratic reciprocity lasted.
• They found no significant differences between treatment and control groups at the 3-month follow-up on the primary outcome measures.
• This aligns with prior research showing brief interventions often have diminishing effects over time without ongoing repetition/engagement.
• It highlights that while the AI assistant improved conversations, a brief discussion is not enough to generate lasting changes in attitudes.
• Repeated or sustained exposure to respect-promoting conversations is likely needed to produce durable effects for long-term impacts.
• This is challenging to implement at scale, underscoring the value of AI for cost-effective intervention even if repetitive conversations are optimal.
• The lack of persistence further indicates the AI did not fundamentally alter participants’ core dispositions – their views reverted once the treatment conversation ended.
• Future research could explore ways to generate more lasting effects, like multiple treated conversations over time.

The follow-up analysis provided no evidence that the AI’s effects persisted months later. This reinforces the brief, subtle nature of the intervention and aligns with expectations from social science. It points to the need for long-term, recurring, positive conversations to improve social norms and attitudes.

More research is needed, but these findings suggest promise for using AI to strengthen democratic norms like reciprocity at scale. As digital spaces expand, this could help counter unproductive polarization.

However, many open questions remain regarding risks and limitations. How might conversational quality change over repeated interactions? Do effects persist in other social contexts? The technology requires prudent governance.

An analysis of some critical risks, limitations, and governance needs for the AI chat assistant technology used in the study:

Risks:

• Potential for bias in language models to propagate harmful stereotypes or unfairly characterize certain groups.
• Possibility of manipulation if used by bad actors to surreptitiously persuade rather than improve tone.
• User overreliance on tools could degrade natural conversation skills over time.

Limitations:

• Narrow focuses only on politeness, validation, and restating. May miss other essential factors in quality conversations.
• It still requires human judgment to accept/modify suggestions appropriately.
• Limited to text-based conversations; doesn’t work for verbal discussions.

Governance Needs:

• Oversight of training data and model development to reduce harmful biases. Audits for fairness.
• Transparency over capabilities and limitations so users have appropriate expectations.
• This means for users to provide feedback to improve suggestions over time.
• Guidelines for ethical use cases that avoid manipulation and respect user agency.
• Regulatory standards for valid claims around benefits of conversational AI.

Risks include biases and manipulation, limitations involving the tool’s narrow focus, and the need for human oversight. Governance is needed to ensure proper training, transparency, user control, and ethical use. Thoughtful governance can help reduce risks and harms while allowing the benefits of improved conversations. Ongoing research should inform policies for conversational AI.

While not a panacea, this initial study suggests AI tools could play a constructive role in facilitating democratic discourse online. However, realizing that potential will require ethical innovation and continued research.

The concluding chapter summarizes key insights from this exploration into whether AI can improve online political conversations.

Challenges and Roadblocks in Implementing AI for Improving Online Political Discourse

1. Complexity of Human Conversation: Human discourse is rich, layered, and complex. While AI can parse language structure, understanding the subtleties, nuances, cultural contexts, and emotions can be challenging.
2. Bias and Ethical Concerns: AI models, including LLMs, can carry the biases in their training data. Without careful oversight, these biases can inadvertently get amplified in online discourses, leading to further polarization.
3. Dependence on Technology: Over-reliance on AI tools can make users dependent, reducing their analytical and conversational skills. Users might begin to expect AI to manage and control every aspect of their conversations.
4. Misuse and Manipulation: Malicious actors can misuse these tools to spread disinformation or manipulate discourses, especially if the technology becomes widely accessible.
5. Loss of Personal Touch: Over-automation can strip away the human element from conversations. The risk is that conversations become more mechanical and less empathetic.
6. Technical Limitations: While AI has made great strides, there are still limitations, especially when handling diverse and multifaceted topics. This can lead to oversimplification or misinterpretation.
7. Privacy Concerns: Monitoring conversations for improving discourse can raise privacy issues. Users must be assured that their conversations aren’t being stored or misused.

Recommendations to Overcome Challenges:

1. Human-AI Collaboration: Instead of fully automating discourse management, AI can suggest improvements. The final decision should remain with the user.
2. Continuous Training and Feedback Loop: AI models should be continuously trained with diverse data and feedback to improve performance and reduce biases.
3. Clear Guidelines and Transparency: Users should be informed about how the AI works, its limitations, and the data it uses. This can build trust and set correct expectations.
4. Regulations and Oversight: To prevent misuse, there should be guidelines and oversight on how these AI tools are used, especially in sensitive areas like political discourse.
5. Ethical Design and Development: Ethical considerations should be at the forefront of designing and developing these AI tools. This includes respecting user agency, ensuring fairness, and being transparent about capabilities.

While AI has the potential to enhance the quality of online political discourse significantly, careful consideration of the challenges and proactive measures to address them is crucial. With a balanced approach, AI can be a valuable tool in fostering constructive and respectful online dialogues.

6. Conclusion

This exploration suggests that thoughtfully implemented artificial intelligence tools like large language models could play a constructive role in improving online political discourse.

The experimental study provides initial evidence that an AI assistant can increase perceptions of conversation quality and democratic reciprocity by helping participants feel understood. It did so without manipulating their views.

The research presented valuable findings on how AI can improve democratic discourse by fostering respectful and understanding online political conversations. Using a developed AI chat assistant, one participant in a conversation received evidence-based suggestions in real-time for rephrasing messages, which led to increased conversation quality and democratic reciprocity. This indicates AI can be crucial in cultivating democratic norms during divisive interactions.

Participants had the autonomy to accept, modify, or dismiss the chatbot’s suggestions, reinforcing human agency within the conversation. The chatbot intervention did not influence participants’ policy positions, demonstrating how AI can significantly enhance political interactions without manipulating views.

The research findings shed light on the potential of AI in promoting a culture of respect and understanding, acting as a counteractive mechanism to spreading misinformation and polarization, often associated with advances in artificial intelligence. Moving forward, more research is necessary to explore these opportunities and to fine-tune the technology and the nuances it must navigate.

Despite the chatbot’s effectiveness during the interventions, the research identified a lack of effect persistence in the long-term. This suggests the need for ongoing intervention in facilitating effective results, emphasizing the need for repeated and sustained exposure to these beneficial conversations to generate lasting change.

While there’s much potential in leveraging AI to strengthen democratic norms, conducting more extensive and longitudinal research is necessary to fully understand its potential and how it can enhance, rather than replace, human communication. Extensive research will also provide more data for essential governance systems and risk mitigation strategies in AI’s role in democratic dialogues.

While more research is needed, these findings point toward promising possibilities for using AI to strengthen democratic norms at scale. As political talk continues online, these tools may help counter unproductive polarization.

However, realizing that potential while mitigating risks requires ethical innovation and governance. The technology must be designed to facilitate democratic deliberation, not drive division. Ongoing research should examine long-term impacts across contexts.

In conclusion, this article argues that the threat of AI exacerbating social divisions is real, but so is its promise to do the opposite. With careful implementation, AI could help citizens have difficult but democratic conversations across lines of difference. And that ability to hear and understand opposing views may be vital for diverse societies to maintain social cohesion in an increasingly digital world.
