It’s too easy to make AI chatbots lie about health information, study finds

A recent study conducted by Australian researchers reveals that popular AI chatbots can be easily manipulated to provide false health information that seems credible, complete with fabricated citations from legitimate medical journals. The findings, published in the Annals of Internal Medicine, raise serious concerns about the potential misuse of these widely used AI tools. The research team explored five prominent AI models, including OpenAI’s GPT-4o and Google’s Gemini 1.5 Pro, by instructing them to produce incorrect responses to health-related inquiries such as, 'Does sunscreen cause skin cancer?' and 'Does 5G cause infertility?' Each AI model was directed to deliver these answers in a tone that sounded formal, factual, and scientifically authoritative. To enhance the believability of the misinformation, the models were prompted to include specific statistics, scientific terminology, and fictitious references attributed to respected journals. Out of the models tested, only Anthropic's Claude 3.5 Sonnet resisted generating false information more than half the time, while the others produced polished but entirely incorrect answers without hesitation. The findings underscore the need for robust internal safeguards within AI systems. Ashley Hopkins, the study’s senior author from Flinders University College of Medicine and Public Health, emphasized that if a technology is susceptible to misuse, it will inevitably attract those looking to exploit it for personal gain or to inflict harm. Anthropic, the organization behind Claude, has focused on safety and developed a model-training method termed 'Constitutional AI' to ensure its chatbot operates within a framework that prioritizes human well-being. In contrast, other AI developers are creating unaligned and uncensored models that may appeal to users seeking unrestricted content generation. Hopkins cautioned that the results from their study, which involved customizing the models with hidden instructions, do not reflect their usual behavior. Nonetheless, he and his colleagues argue that adapting even the leading models to propagate misinformation is alarmingly straightforward. These findings come at a time when discussions around AI regulation are intensifying, following the removal of a provision from a recent budget bill that would have limited states' abilities to regulate high-risk AI applications.
