Our findings show that liking the main post is different from liking comments. The fear of isolation and opinion congruence did not have significant effects for liking comments. Liking the Facebook post could indicate support for the contents of the post, i.e., the news story but not the contents of the comments. Hence, participants who liked the Facebook post could have judged it on its own merits as a news story, rather than evaluating it as a unit that is also inclusive of the comments. Liking the Facebook post may also depend on other factors such as personal relevance: users who like a post may be doing so in the hope that the issue may be given greater prominence as their own egocentric public. The psychology behind liking Facebook posts versus liking comments is an area for future research.
