概要	Many online news-platform users read anonymous comments posted by other users. This study examines how such comments influence readers’ impressions of online news articles using lifestyle content, where strong pre-existing attitudes are unlikely. In Study 1 (N = 1,600), comment stance significantly affected impression formation, with opposing comments exerting a stronger influence than supportive ones. In contrast, majority agreement—manipulated by displaying the number of “good” reactions—did not significantly affect impressions. Study 2 (N = 1,337) investigated the effects of emotional intensity and level of attention. The results showed that emotionally intense comments led to more negative impressions of the articles. Notably, comment stance influenced impressions regardless of the level of attention paid to the comments. Based on these findings, further experiments are needed to explore the formation and maintenance of attitudes toward controversial topics.
