CoinWorld News, Oulu University in Finland recently issued a press release stating that the university's researchers, in collaboration with international colleagues, have developed an artificial intelligence (AI) chatbot that uses the "cognitive inoculation" method to help people resist misinformation in the health field. The release pointed out that in recent years, generative AI tools have rapidly developed, making it easier to produce and spread false or misleading content on a large scale, while AI can also be used to combat misinformation. The chatbot, named forty, adopts the "cognitive inoculation" approach derived from social psychology, which essentially involves exposing people to "weakened" versions of false ideas under controlled conditions to enhance their resistance to misinformation in real-world environments. The research team stated that its principle is similar to how the human body strengthens its immune system through vaccination.
