Viés noticioso e exposição seletiva nos telejornais brasileiros durante a pandemia de COVID-19
Bibliographic record
Abstract
Este artigo investiga a ocorrência da exposição seletiva no Brasil, tendo em vista a frequência com que os brasileiros disseram buscar informações sobre a pandemia de COVID-19 no Jornal Nacional e no Jornal da Record. Utiliza dados de uma análise de conteúdo da cobertura desses veículos acerca do assunto em 2020 e os dados de uma pesquisa de opinião pública nacional. As análises realizadas mostram que o partidarismo e a religião foram importantes preditores do consumo de notícias desses veículos. Evangélicos e adeptos do “partido do Bolsonaro” eram telespectadores mais assíduos do Jornal da Record; católicos, partidários de outras legendas e apartidários consumiam mais o Jornal Nacional. Esses resultados indicam que os brasileiros consomem notícias em consonância com suas convicções políticas e que alguns grupos podem estar recebendo menos informação sobre a COVID-19.

How this classification was reachedexpand
Full frame distilled prediction
Teacher imitationNot calibrated prevalence, not ground truth. Human validation pending. Learned from the 10,348 direct Codex labels and 10,348 direct Gemma labels. Candidate is the union of thresholded teacher heads; consensus is their intersection. These outputs are machine_predicted_unvalidated and are not human labels or direct frontier model labels.

Machine scores (provisional)
The two teacher heads of the student model, read on this work. A score orders the frame for review; it never asserts a category, and the validation status ships verbatim with every row.
Baseline scores from an immature model (maturity gate not passed, 7 training rounds). Scores rank; they never assert a category.
score_only:v0-immature-baseline · verbatim from the scoring run: score_only means the number may rank works, and no category label ships from itClassification
machine, unvalidatedMachine predicted; a candidate call from one teacher head, not a consensus.
