Analyzing survey data on the issue of genetically modified foods in South Korea, this study explores the role of news media in facilitating informed issue evaluation. Respondents who read a newspaper more often were more knowledgeable about the issue. Also, heavy newspaper readers were more able than light readers to hold "consistent" views on different aspects of the issue. When it comes to television news, heavy viewers held stronger opinions than light viewers on the key issue attributes. News media use seems to allow the audience to engage in greater cognitive elaboration, helping them to make an informed and deliberate issue evaluation.
