The application of the theory of truth in philosophy can make an important contribution to the strategy for eradicating hoaxes in the digital era. Hoaxes, as misinformation and often deliberately spread for certain purposes, have a broad negative impact, especially in the formation of public opinion and social stability. In this context, theories of truth such as correspondence, coherence, and pragmatism can be used to evaluate and identify the truth of information spread in cyberspace. Correspondence theory, for example, can be used to confirm whether information corresponds to objective facts. Coherence theory, on the other hand, prioritizes the consistency of information with a wider system of knowledge, while pragmatism theory assesses truth based on the practical impact of receiving information. The application of these theories in a hoax eradication strategy involves media education, increasing digital literacy, and developing information verification algorithms that prioritize the principles of philosophical truth. With this approach, it is hoped that the public will be smarter in filtering information, so that the spread of hoaxes can be minimized and public trust in digital media can be restored.
