AI Chatbots Nearly Double Rate of Misinformation Spread in One Year

Thumbnail Image

The information displayed in the AIM should not be reported as representing the official views of the OECD or of its member countries.

A NewsGuard report finds that leading AI chatbots, including ChatGPT and Meta, now provide false or misleading information up to 40% of the time, nearly doubling the misinformation rate from 18% to 35% in one year. The AI systems often treat unreliable sources as credible, amplifying propaganda and contaminating the information ecosystem.[AI generated]

Why's our monitor labelling this an incident or hazard?

The event involves AI systems (language models/chatbots) actively spreading false information and propaganda, which constitutes harm to communities by undermining truthful information and potentially influencing public opinion and social stability. Since the article describes this harm as already occurring and quantifies the extent of misinformation, it qualifies as an AI Incident under the framework, specifically harm to communities due to the AI systems' outputs.[AI generated]

Why's our monitor labelling this an incident or hazard?
The article explicitly involves AI systems (large language models/chatbots) that generate content and are spreading misinformation. The harm described is the spread of false information and propaganda, which harms communities by contaminating the information ecosystem. Since the harm is described as increasing and potentially normalizing but not documented as a specific realized incident causing harm, this fits the definition of an AI Hazard — an event or circumstance where AI use could plausibly lead to harm. The report's warning about the risk of normalizing misinformation and propaganda through AI systems' outputs aligns with plausible future harm. There is no description of a concrete incident with direct or indirect realized harm, so it is not an AI Incident. It is not merely complementary information because the main focus is on the risk and increase of misinformation, not on responses or updates to past incidents. Therefore, the classification is AI Hazard.
