Abstract(s)
A propagação de fake news tornou-se uma preocupação global, com consequências graves
para a integridade da informação, a formação de opiniões e o aumento da desinformação.
Diante desse cenário, a presente investigação tem como objetivo analisar o impacto das
Fake News sobre meios midiáticos na intenção de disseminação das notícias e na atenção
dos usuários. Com base em um estudo experimental envolvendo 180 participantes, foram
manipuladas notícias falsas e verdadeiras, geradas por humanos e por Inteligência
Artificial (IA), para verificar a percepção dos usuários sobre a veracidade e a propensão
de compartilhamento. O estudo também analisou o papel do confirmation bias como
mediador no comportamento dos participantes em relação à disseminação e à atenção às
notícias. Os resultados revelam que as fake news têm maior poder de disseminação em
comparação com as notícias reais, especialmente quando geradas por IA, mas não
demonstram maior capacidade de captar a atenção dos usuários. O confirmation bias
mostrou-se um fator importante tanto para a disseminação quanto para a atenção dedicada
às notícias que confirmam crenças pré-existentes.
The spread of fake news has become a global concern, with serious consequences for the integrity of information, the formation of opinions, and the rise of misinformation. Considering this scenario, the present investigation aims to analyze the impact of fake news on media outlets in terms of news dissemination intentions and user attention. Based on an experimental study with 180 participants, fake and real news generated by both humans and Artificial Intelligence (AI) were manipulated to assess users' perceptions of truthfulness and their likelihood to share the news. The study also explored the role of confirmation bias as a mediator in participants' behavior regarding news dissemination and attention. The results show that fake news has greater dissemination potential compared to real news, especially when generated by AI, but does not exhibit a higher capacity to capture users' attention. Confirmation bias was found to be a significant factor for both news dissemination and the attention given to news that aligns with pre-existing beliefs.
