SAN FRANCISCO -- Positive opinions are more influential than negative ones, at least on the Internet. If an article is "liked" on a website such as Facebook, new readers are more likely to approve of it, according to a study published in the journal Science. While the positive reactions create a "herding" effect, negative views don't appear to affect people the same way. The comments that got a positive boost from the researchers subsequently took off in popularity, receiving a 25 per cent higher rating on average from other users.
