When we believe something, the belief is usually based on available evidence. If the evidence supporting the belief is proven false, or if contradictory evidence is presented, it would be reasonable to reject the belief. However, this does not always happen in practice. People may hold onto their existing beliefs by attempting to justify evidence that is objectively false, or by ignoring contradictory evidence. Such apparently irrational responses to evidence are particularly common within filter bubble and echo chambers. This presentation aims to explore how people come to believe disseminated misinformation and disinformation, and how these beliefs are maintained and reinforced. It focuses specifically on reactions to evidence in belief formation within filter bubble and echo chambers, seeking to uncover the mechanisms behind these processes from a philosophical perspective. Additionally, it examines how a philosophical understanding of these phenomena can contribute to effective strategies for addressing misinformation and disinformation that may be spread by AI.
