Following the herd: Online ‘likes’ multiply themselves

In ScienceNews:

When rating things online, people tend to follow the herd. A single random “like” can influence a comment’s score at a social news site, researchers report in the Aug. 9 issue of Science.

An unearned up vote packed a surprising punch. The first person to view a randomly liked comment was 32 percent more likely to rate it positively than to do the same with a comment that had received no vote. In the long run, boosted comments’ final scores were 25 percent higher than scores of untouched comments. Random negative votes did not affect a comment’s final rating because users compensated with extra up votes.
