Privacy-focused search engine DuckDuckGo presented false information in its artificial intelligence-supported search results that Donald Trump and JD Vance died due to rabies. This situation once again revealed how the artificial intelligence models used by the search engine process false information.

These false conclusions appeared largely as part of a coordinated disinformation campaign on the Internet. The r/poisonai community on Reddit aims to manipulate the sources that feed artificial intelligence models by deliberately producing false information in order to mislead them.

Artificial Intelligence Models and Disinformation Risk

DuckDuckGo’s search tool and chatbot, Duck.ai, is powered by several third-party models, including Anthropic’s Claude 4.5 Haiku, Mistral AI’s Mistral Small 3 24B, and OpenAI’s GPT-5.4 nano, GPT-5.4 small, and gpt-oss-120b. The fact that these models pull information from platforms such as Reddit causes manipulative content on the platform to be reflected directly in the search results.

A report by Search Engine Land confirms that Reddit has become one of the most frequently referenced sources by AI models today. This shows how vulnerable artificial intelligence-supported search engines can be coordinated disinformation attempts on the internet.

Earlier this year, DuckDuckGo managed to increase the number of users by positioning itself as an artificial intelligence-free alternative to Google. The company released a browser add-on that claimed to purify search results from artificial intelligence contamination, and recorded a 30 percent increase in application download rates in this process.

Strategic Error and User Trust

On the one hand, the company takes a stance opposite to artificial intelligence and tries to expand its user base, on the other hand, it continues to incorporate artificial intelligence features. This contradictory approach is considered a risk factor that can damage users’ trust in search results.

This move by DuckDuckGo is likened to Mozilla’s decision to integrate artificial intelligence while trying to attract users escaping Chrome to Firefox. Although Mozilla had to add an AI kill switch later, experts argue that it is safer to reject such technologies from the beginning.

The company’s retention of artificial intelligence features sparks discussions that question the reliability of the brand. We are curious about your opinions about the reliability of artificial intelligence-supported search results. How do you think these misconceptions affect the belief in search engines?
