The present experiment investigated (1) how readers' comments on Internet news portals and perceived public opinion might affect individuals' perceptions of news slant and (2) how issue involvement might moderate such effects. In so doing, I pitted two competing explanations for the hostile media effect against each other: biased standards(Eveland & Shah, 2003) and defensive processing(e.g., Gunther & Liebhart, 2006). In a web-based experiment, 184 participants were presented with either a neutral news article on animal testing or the article plus others' comments against animal testing. Results showed that (1) participants inferred the general public opinion from several anonymous others' comments and (2) those perceiving the congenial(vs. uncongenial) opinion climate attributed stronger hostility to the news report, lending support to the defensive processing account. Highly involved individuals were more likely to perceive the news slant in line with the opinions expressed in others' comments, suggesting that motivated information processing can induce a perceptual bias(i.e., assimilation).
