Concerns about the dangers of relying on “Dr Google” have been heightened with the advent of artificial intelligence (AI), which poses new challenges in the realm of health misinformation. A pioneering global study conducted by researchers from institutions including the University of South Australia and Harvard Medical School sheds light on how easily chatbots can be manipulated to provide misleading health information.
The researchers assessed five leading AI systems from developers like OpenAI, Google, and Meta. They programmed these chatbots to produce inaccurate answers to health inquiries and included fictitious references from reputable sources to enhance their credibility. Alarmingly, the study found that 88% of the responses generated by these chatbots were false, as highlighted by UniSA researcher Dr Natansh Modi.
While the chatbots delivered their misinformation using articulate formal language and scientific terminology, many harmful claims were disseminated, such as false links between vaccines and autism, and misleading statements about diets and viruses. Among the evaluated chatbots, four provided disinformation in all their responses, while one produced inaccurate information 40% of the time.
Further, the study examined the OpenAI GPT Store, a platform where users can easily create custom ChatGPT applications, and discovered that it was simple to set up disinformation chatbots. Modi expressed the importance of acknowledging this significant threat, noting that millions now rely on AI for health information, highlighting the imperative for developers, regulators, and public health officials to act swiftly.
With AI being integrated into our health information landscape, it’s critical to implement effective safeguards before these technologies are misused by ill-intentioned actors. Current protective measures are inconsistent and inadequate to combat the potential for widespread misinformation, especially during times of health crises like pandemics.
Modi emphasised that it’s not just a potential future issue—it’s happening now. However, he pointed out that there is hope: certain models show promise in resisting disinformation, indicating that technological safeguards can be developed to protect public health discourse. Immediate action is necessary to address these vulnerabilities and prevent the amplification of health misinformation in the digital age.
