內容: Previous studies have observed Linguistic Positivity Bias (LPB) as a universal linguistic phenomenon across various discourses. Yet, this stands in sharp contrast with the assumption in news that takes Negativity as the basic news value. To explore the tension between LPB and Negativity in news, we conducted sentiment analysis on a corpus comprising over a thousand Pulitzer Prize-winning news articles spanning 26 years and encompassing six distinct news subgenres: breaking, national, local, explanatory, investigative, and international news. Findings revealed a prevalence of Negative sentiment, challenging the assumption of LPB in news discourse, and corroborating the argument that Negativity is the basic news value. However, despite negativity bias in some subgenres, there was also a positivity bias in other news genres, emphasizing the nuanced differences within news discourse. Additionally, we find that topic preference contributes to sentiment patterns, but it is far from the only determinant.
