Rarely do I read an academic study that terrifies me.  Well…unfortunately my colleague sent me a study that sent chills down my spine.  The future is here, and we aren’t likely to be prepared for it.

As we have written before, persuasion is hard. If you’ve ever tried to convince a friend on any political issue or even to watch your favorite show (and failed), you know how tough it can be. Now imagine a chatbot trying to do it! Crazy, right? Well, not so much.

Recent research shows artificial intelligence (AI) might be better at persuasion than you think. Let’s dive into the science behind this surprising finding.

Introduction

This study explores whether AI, specifically GPT-3, can influence human opinions on political issues. The research tackles a simple yet profound question: Can AI persuade as effectively as humans? Spoiler alert: The answer is yes—and it’s got people talking about the implications for politics and beyond.

Conclusion

This study marks a step in understanding AI’s role in persuasion. As AI tools continue to advance, their capacity to shape opinions could significantly influence politics, advertising, and even our interpersonal communication.

While the observed effects may seem modest, the effects are small with humans.  The real power of AI lies in its scalability. When combined with automation, this technology poses a potential threat, particularly in the hands of malicious actors. The ability to produce persuasive messages at scale could amplify foreign interference in elections or facilitate widespread misinformation campaigns.

Although I hesitate to advocate for additional regulations, the immense power of these tools demands responsibility.  It is why the authors write, “Our findings call for immediate consideration of regulations of the use of AI in political activities.” 

Moreover, we cannot overlook the role of platforms like TikTok.  Our youth are unknowingly contributing to the development of AI technologies that could potentially be leveraged against us.

I agree, policymakers must remain vigilant, as the risks of unregulated use could undermine public trust.  

Reflecting on these implications, I suddenly feel a bit like a Luddite.   UGH!

Research shows that when local newspapers fade away:

• Local Political Awareness Erodes: Citizens know less about local issues and are less likely to participate in state and local politics.
• Nationalization of Politics Intensifies: All politics becomes national politics.
• Democratic Accountability Weakens: Local corruption thrives when no one is watching.
• Civic Engagement Declines: Voter turnout decreases, especially in smaller communities.

Now, new findings tie the death of local newspapers to something even more worrisome: increased polarization and an increase in straight-ticket voting.

Let’s dive into the academic research that unpacks these intriguing connections.

Paper Introduction

The researchers sought to answer a pressing question: what happens to voting behavior when local newspapers shut down?

Specifically, they examined the effect of these closures on split-ticket voting—where voters pick candidates from different parties for different offices.

The hypothesis? Fewer newspapers might mean less local political news, leading voters to rely on national, partisan sources instead. Spoiler alert: the hypothesis holds water.

Methodology

This study employed a quasi-experimental design using genetic matching.

It compared counties with and without newspaper closures between 2009 and 2012 while controlling for demographic and economic factors.

The researchers analyzed 110 closures and measured changes in split-ticket voting by looking at differences in votes for presidential and senatorial candidates in 2012. Their main dataset came from the National Digital Newspaper Program and other demographic sources.

Results and Findings

1. 1. • A 1.9% Drop in Split-Ticket Voting Counties that lost a local newspaper saw a decline in split-ticket voting, meaning voters were more likely to align their choices strictly with party lines. While the percentage may seem small, this represents a meaningful uptick in polarization.
      • The Role of National News Voters in affected counties appeared to turn to national media, which is brimming with partisan rhetoric. Without local reporting to highlight nuanced, community-specific political issues, voters defaulted to “us versus them” party cues.
      • It’s Not About Information Loss The researchers ruled out the idea that voters simply lacked enough political information. Instead, they suggested that nationalized media drowned out diverse perspectives, emphasizing polarized party identities.

Critiques and Areas for Future Research

1. Is 1.9% really that large? This study look at changes for national offices.  At the local level (congressional & state legislatures), it is likely that a voter lives in a safe district, and 1.9% isn’t likely to make a huge difference.
2. Generality of Results:
   The study used counties as its unit of analysis, which may mask individual-level differences in behavior. Future research could incorporate voter surveys for a more granular view.
3. Limited Time Frame:
   The analysis stops at 2012 (darn peer review….), and it’s unclear whether the trends persisted or grew stronger in subsequent years as media consolidation continued.  The
4. Geographic:
   Regions with robust alternative media sources might experience less polarization than those with few news outlets.  Exploring the rural/urban divide specifically and expanding the dataset to include these factors could yield deeper insights.

Conclusion

Local newspapers are more than just sources for restaurant health reports, high school football scores, and lottery numbers.

They serve as a vital check against potential corruption and the increasing influence of nationalized, hyper-partisan news outlets.

This study presents a clear message:  local journalism is about more than mere nostalgia – it’s about mitigating the growing political divide in America.

Sadly, I believe the decline of local newspapers is now irreversible.

Despite recognizing the effects, I confess I cancelled my own subscription to the local newspaper.  The “local” newspaper had lost its local focus, and honestly, the overall product is terrible. (To add insult to injury, the cancellation process was appalling. After paying online, I was forced to speak with a persistent salesperson who tried to pressure me with “special deals” “just for me.”)

Nevertheless, it’s essential that we grasp the significant consequences of this trend.

Introduction to Polarization

I’ve written about polarization many times over the past year. It’s one of the most significant factors in U.S. politics today, if not the most. Typically, I focus on one individual study or paper, but today I want to zoom out and examine the findings in a broader context.

Neo-Beginnings

Every graduate student in political science since the early 2010s has likely written a paper reconciling the academic “disagreement” between Morris Fiorina and Alan Abramowitz.

As far as academic “disagreements” go this one was…combative and sharp.   It was / is a doozy.

The argument in a nutshell:

• • Fiorina argues that polarization is primarily an elite-driven phenomenon, with political elites (politicians, activists, media) becoming more polarized while the mass public remains relatively moderate. For the general public, he suggests that there is more sorting than true ideological polarization—voters align their party identification with their preferences, but they are not deeply divided on most policy issues. (Fiorina et al, 2011)
• • Abramowitz, on the other hand, emphasizes that polarization is widespread among the electorate, especially among the most engaged citizens, who have become more ideologically consistent and politically divided. He argues that as the electorate becomes more polarized, affective polarization (i.e., the emotional dislike of opposing partisans) increases. (Abramowitz, 2017)

For me, it was strange argument because their views are compatible with each other, when you ask the question, “Under what circumstances can both of these positions be correct?”  (Especially when we have the ability to consider additional research?)

Among political elites, Abramowitz is right—polarization is high, emotional, and often extreme. Among non-elites, Fiorina’s position holds more weight, but research suggests he may be looking in the wrong place.

Most of the general public doesn’t deeply care about politics. This is estimated by some to be 20-30% of the people (Kalmoe, 2020).  I have seen some that estimate it as low as 15% (Speaking of Psychology: The psychology behind our political divide, with Keith Payne, PhD., n.d.).

However, when polled about policy, many give moderate responses—what they often mean is, “I don’t know, and I don’t care.” This middle-of-the-road answer satisfies the pollster but doesn’t represent how they’ll vote.

Instead, their behavior is guided by cues from political leaders or social circles. These cues encourage distrust and dislike of the opposing party, making voter behavior appear polarized even when personal ideology isn’t.

Said another way, it is really difficult for any pollster to capture an answer posed about the funding mechanisms of charter schools when the answer is likely closer to:

“meh, I don’t really care about this issue and/or I am not knowledgeable about the issue.  I’ll answer your question with a middle of the road answer because you asked politely – but know I will very likely govern my political behavior by cues received from my political party – especially political leaders – and/or my social circle that I value which are now highly correlated.  And both of those are likely to tell me not to like the “other” party and that is basic human nature anyway, so my political behavior and voting will appear polarized too.” – voter

To add some final nuance: Abramowitz’s view dominates in low-turnout elections, like primaries, where highly engaged voters participate in mostly non-competitive districts. (and well since political elites and political nerds tend to hang out together… their perception is of extreme polarization…leading to more affect polarization…leading the public…)

But I digress, Fiorina’s perspective becomes more relevant in general elections, where turnout is higher and broader.

Drivers of Polarization

Let’s shift gears to what drives polarization. Looking at U.S. trends since the 1960s, the literature points to several familiar themes:

• • Economic inequality: The growing gap between rich and poor (McCarty et al., 2007; Zacher, 2024).
  • Racial issues: A key driver in the U.S. (McAdam, 2015).
  • Partisan realignment: Spurred by economic inequality and civil rights movements (Highton, 2020; Kuziemko & Washington, 2018).
  • Media fragmentation: The rise of ideologically selective media (Prior, 2005; Iyengar & Hahn, 2009).
  • Geographic sorting: Americans increasingly live near like-minded neighbors (Cho et al., 2013).
  • Uncompetitive districts: Less competition leads to more extreme partisanship (Stonecash et al., 2018).

Human Nature and Affect

While these structural factors matter, in my take of the subject if I zoom out: basic human nature and human psychology are the real driving forces.

Most polarization today isn’t driven by ideology but by emotion and affect—a gut-level dislike of “others” (Young & de-Wit, 2024). Party and geographic sorting (Cho et al., 2013) make it easier to identify “them” as “others”, and human nature does the rest. We’re hardwired to distrust outsiders.

This is where Fiorina was looking in the wrong place for polarization.  For many, politics is not not a well thought set of political ideology or issue stances (Kalmoe, 2020).

Rather for many, politics is driven by a gut reaction and the details are outsourced to elites (Lenz, 2013), who are happy to exploit these emotional divides for power and re-election (Karol, 2015).

Impacts on Governing

The consequences of affective polarization are severe:

1. Growing contempt: Americans increasingly distrust “others” (Geiger, 2014).
2. Exaggerated perceptions: We overestimate how extreme our opponents’ positions really are (Lees & Cikara, 2020; Ruggeri et al., 2021).
3. Declining cooperation: Dislike makes compromise nearly impossible (Geiger, 2014b).
4. Government dysfunction: Legislative gridlock is the norm (Binder, 2004).
5. Eroding trust: Polarization harms trust in government (American Academy, 2023), media (Shearer, 2024), and even each other (Hetherington & Rudolph, 2017; Lee, 2022).
6. Risk of violence: At its extreme , polarization creates “an environment in which political violence is more socially acceptable and frequent”  (Piazza, 2023).

What’s Next?

Can anything be done about polarization?  Can we stop this polarization?  Is the current polariation any worse than the polarization seen pre-1960?  All questions for another blog post.

I’ve briefly touched on this topic before in What is the Solution to Extreme Divisiveness? You can check it out here. Spoiler: one solution might involve sharing scotch with someone you disagree with.

But what’s next topic deserves another deep dive. Stay tuned.
