Resumo

A presente pesquisa analisa os determinantes da confiança da opinião pública europeia na ONU em contexto de guerra e desordem informacional. Propõe-se um modelo que integra três dimensões: informacional, heurística e identitária/polarizadora, e um indicador institucional: perceção de liberdade da imprensa. A análise baseia-se em dados do Eurobarómetro 98.2, e recorre à ACP e à regressão logística binária. Os resultados indicam que a confiança nos media é o preditor mais robusto, confirmando a importância das heurísticas de credibilidade. O uso de rádio e imprensa tem efeitos pequenos, mas consistentes, enquanto os media digitais revelam impacto ambivalente e estatisticamente nulo. A participação em debates políticos online associa-se positivamente à confiança, bem como à perceção de liberdade da imprensa. O estudo evidencia a articulação entre opinião pública, media e confiança institucional, oferecendo orientações para políticas de integridade informacional e literacia mediática.
