Harry Styles is the happiest celebrity on Twitter, new research has found.
The One Direction singer came out on top when scientists analysed the emotions expressed in the social media output of the 100 people with the most Twitter followers.
The team from analytic firm Adoreboard examined social media messages stretching back eight months, using special software to detect and interpret emotions in the text.
The study found that Harry’s mood certainly hasn’t dipped as a consequence of 1D’s forthcoming parting of the ways next March.
The 21-year-old pop star claimed top spot ahead of singer-songwriter Adele and the Indian film actor Aamir Khan.
The Adoreboard data scientists, who are based at Queen’s University, Belfast, specialise in the development of software that can detect emotions vented online.
Using their analytics tools, they can identify emotional patterns in billions of tweets, such as joy, rage, anger, surprise, trust and annoyance.
The study also examined why certain celebrity tweets were either retweeted or favourited.
Chris Johnston, chief executive of Adoreboard, said the findings provided a “unique snapshot” of the range of different moods that celebrities feel. He said the data could have implications for the way brands and even politicians communicate on-line.
“Not only is Harry Styles one of the most popular celebs on Twitter with over 24 million followers but is also the most upbeat in terms of mood,” said Mr Johnston.
“Styles has become a global brand and like any brand is conscious how he communicates online. The study provides a new dimension by looking at the impact of specific emotions that people communicate on platforms like Twitter.
“As part of the research we’ve identified that those celebrities that express strong emotions like joy or rage on Twitter are more likely to receive retweets or favourites. We found that the strength of each emotion expressed by a celebrity – known as their ‘activation levels’ – provides a good indicator as to how often they will be retweeted.”
Other ‘happy’ stars in the top ten include Ariana Grande, US talk show host Jimmy Fallon, Shakira and Emma Watson.
