Many studies and their findings are available concerning most aspects of online user comments and their effects. Two experimental studies were conducted to examine the quality of a journalistic product and the valence of user comments. The results indicate that, overall, high-quality journalistic products were evaluated as (slightly) better than low-quality versions. Furthermore, users evaluated the quality of journalistic products with positive user comments as better than the quality of identical products with negative comments. Considering that, in reality, user comments are predominantly critical, it is worrying that these comments have rather negative effects on the evaluation of journalistic work.
