AI and Misinformation in the US Election: Social Media, Deepfakes and Foreign Interference

Summary

The Naked Scientists explore how AI and social media shape the closest US presidential race in memory, examining misinformation, foreign interference, and countermeasures. The discussion spans how platforms influence exposure to campaign content, the rise of AI generated content and deepfakes, and strategies to inoculate the public against misleading claims. The episode includes perspectives from US politics experts and international researchers on the scale and speed of modern information manipulation and what can be done to protect democratic processes.

• AI and social media are central to how voters encounter political information
• Misinformation and deepfakes can tilt close elections if left unchecked
• Inoculation and prebunking can immunize some voters against misinformation
• Foreign powers and platform owners shape or distort the information environment

Introduction

The podcast explores the intersection of technology, AI and elections, focusing on how social media and digital platforms influence voter opinions in the United States, and how this environment interacts with the closest presidential race in memory.

AI and social media in elections

The discussion highlights how campaigns have leveraged large digital data sets and AI to tailor messaging, and how platforms like Facebook, X (formerly Twitter), Instagram and TikTok function as the primary channels for quick, bite sized content. The guests note that social media increasingly dominates traditional media in terms of immediacy, and that platform ownership can affect the political content that users see. The Elon Musk led changes to X and his public stance are used to illustrate how platform dynamics can tilt information exposure and influence around elections.

Disinformation versus misinformation and inoculation strategies

A Cambridge based psychologist explains misinformation as false or misleading content, with disinformation being misinformation produced with harmful intent. The podcast discusses how misinformation around election results—such as claims of fraud—could be exploited. A key defense strategy described is psychological inoculation or pre bunking, where people are exposed to weakened forms of misleading claims and techniques used to spread them, plus refutations, to build up mental defenses before exposure. Early testing suggests inoculation can reduce susceptibility by roughly a third in a nationally representative US sample, though effectiveness may vary by context and timing.

Deepfakes, strategic distraction and AI scale

Barbara Trish from Grinnell College outlines the four ways AI could influence elections: information quality, deepfakes, strategic distraction and foreign interference. Deepfakes and AI generated audio or video may mislead voters, while strategic distraction could overwhelm election administration with automated inquiries, complicating the voting process. The discussion also covers how AI can enable foreign actors to scale interference efforts rapidly, and how such tactics might be deployed against political actors abroad as well as domestically.

Foreign interference and state actors

Defense and security analyst Michael Clarke explains how Russia, Iran and China engage in cyber mischief and influence operations, using AI to identify swing voters and craft targeted messaging. He notes that Russia has historically pursued strategic outcomes such as shaping U S policy in Ukraine and other arenas, with the potential intent of tilting elections toward favored candidates. The interview emphasizes the difficulty of stopping interference and the need for greater awareness and resilience within democratic systems.

Takeaways and public guidance

The podcast closes with practical guidance for listeners to critically evaluate information, rely on mainstream trusted outlets, and participate in democratic processes. It also discusses ongoing work to build resilience against misinformation and calls for peaceful transfer of power regardless of election outcomes.
