Sharing happy news with your Twitter followers? Odds are, they’re more likely to share it than a negative post according to a recent study.

An analysis of 3,800 randomly chosen Twitter users found that emotions spread virally through Twitter feeds – with positive emotions far more likely to spread than negative ones.

“What you tweet and share on social media outlets matters. Often, you’re not just expressing yourself – you’re influencing others,” said Emilio Ferrara, lead author of the study and a computer scientist at the USC Viterbi School of Engineering’s Information Sciences Institute. Ferrara collaborated with Zeyao Yang of Indiana University.

Ferrara and Yang used an algorithm that measures the emotional value of tweets, rating them as positive, negative or neutral. They compared the sentiment of a user’s tweet to the ratio of the sentiments of all of the tweets that appeared in that user’s feed during the hour before. Higher-than-average numbers of positive tweets in the feed were associated with the production of positive tweets, and higher-than-average numbers of negative tweets were associated with the production of negative tweets.

About 20 percent of Twitter users were deemed highly susceptible to what the researchers described as “emotional contagion” – with more than half of their tweets affected. Those users were four times more likely to be affected by positive tweets than negative ones.

Those least likely to be affected by emotional contagion were still a little less than twice as likely to be affected by positive tweets as negative ones. Over all users, regardless of susceptibility, positive emotions were found to be more contagious than negative emotions.

The study builds on decades of research demonstrating first that emotions can be spread through person-to-person contacts, and now finding that they can spread through online interactions as well.

Facebook drew criticism last year for attempting to demonstrate a similar effect by tweaking 700,000 users’ news feeds. Unlike that experiment, Ferrara and Yang did not manipulate what Twitter users were experiencing – rather, they simply observed what was already happening and analysed it.

So what does that mean for marketers? Positive news tweets are more likely to go viral than negative tweets…especially if they contain positive emotions! Get that smiley emoji ready for lauch!
