Chatbots reject election lies, then help make them
Chatbots often challenged election conspiracy theories in Brennan Center tests, but the same research found that AI tools could still produce convincing images, videos and official-looking documents built around false claims. The tension sits at the center of the organization’s election-security findings, detailed in an Atlantic report published October 9: safeguards may stop a direct request, yet fail when users change models, switch versions or rework the request.
The Brennan Center researchers tested six image and video tools, including ChatGPT, Gemini, Grok, Meta AI, Runway and Flux.2. They generated scenes suggesting ballot fraud, noncitizen voting and an FBI investigation of a voter-registration group. The researchers also reproduced a Russian disinformation video that circulated before the 2024 U.S. presidential election, using a publicly available AI tool.
“They’re easily circumventable, and the tools themselves make it easy to circumvent them,” Lawrence Norden, the Brennan Center’s vice president of elections and government, told The Atlantic. The test results show what researchers could produce in controlled trials; they do not establish that a real-world campaign used these materials or that any votes were affected.
A refusal in one version did not carry across tools
The researchers did not rely on a single prompt asking a chatbot to create a fake image. They first asked four chatbots for research and strategic advice about how to frame familiar election-fraud narratives. They assembled that guidance into instructions, then used it to request image-generation prompts. Grok produced a set of 100 prompts; other chatbots refused that request, but the researchers could still use the prompts across image-generation tools.
In one test, Runway produced an image of someone altering postmarks, but replaced ballots with ordinary mail. Researchers moved the image to Gemini and asked it to swap in ballots; Gemini complied. A separate test found a difference between ChatGPT’s versions: its “thinking” mode declined to make a deceptive government memo and offered a visibly fictional version, while its “instant” mode removed the watermark when asked.
The Brennan Center also measured inconsistent responses to identical image-generation requests across versions. Meta AI’s versions differed in whether they accepted or denied a prompt 67 percent of the time; the figure was 28 percent for ChatGPT, 22 percent for Grok and 10 percent for Gemini. Those figures describe agreement on whether to generate an image or refuse, not how convincing the resulting images were.
Chatbots also struggled to verify fabricated images
The researchers found a second weakness: several chatbots misidentified AI-generated election images as authentic. In follow-up tests reported October 5, Brennan Center researcher Abdiaziz Ahmed said that four of six chatbots initially treated a fabricated image of postal workers sorting election mail as real. Gemini was the only tested chatbot that checked the image’s embedded origin data; some other models noticed a visible watermark but dismissed it.
The test matters because AI-generated imagery can be used not only to create a false claim but also to give that claim apparent evidence. The Atlantic reported that when Brennan Center researchers showed other chatbots the generated images and asked whether they were real, several models failed to identify them as synthetic. A chatbot’s confident assessment therefore cannot, by itself, establish that an election image depicts a real event.
Truthful answers do not settle the risk
The findings were not uniformly negative. In tests of election questions, the six products—ChatGPT, Gemini, Grok, Claude, Perplexity and DeepSeek—generally pushed back on common conspiracy theories, even when researchers posed as skeptical users and pressed them. But the Brennan Center reported inaccuracies and weak citations in those exchanges, while the Atlantic noted that some chatbot replies used friendly language that could sound as if they validated a user’s suspicions.
The divide is consequential: answering a familiar conspiracy theory and refusing to generate persuasive false evidence are different safety tasks. A safeguard that holds for one version or one prompt may not hold when a user changes the tool or returns with a modified request. Researchers’ tests expose that gap, while stopping short of showing that the tested content has been deployed to disrupt an election.
