Fig. 2: Main effect of comment sentiment on attitude.
From: The processing and evaluation of news content on social media is influenced by peer-user commentary

Participants viewed news content on a manipulated but ostensibly real social networking site. We manipulated the sentiment of user comments to be either positive, negative, both (i.e., ‘mixed’), or no comments. Error bars represent 95% CIs, significant differences (p < 0.011) are indicated with asterisks.
