So how satisfied are your friends and colleagues with their lives? One way to find out is to check out their tweets.


Researchers at the University of Iowa have recently reported the results of analysing around 3 billion tweets between October 2012 to October 2014.

They found people’s feelings of long-term happiness and satisfaction remained steady over time, unaffected by external events. This is really interesting because previous social media-based research into short-term happiness found people's daily moods were heavily influenced by external events.

Satisfied users are active on Twitter for longer, use more hashtags and exclamation marks but fewer URLs. Satisfied tweeters are also more likely to express positive emotions and to use words relating to money and religion.

Dissatisfied tweeters use more personal pronouns and swear words in their tweets. They are more likely to express negative emotion, anger, and sadness; words related to death, depression, and anxiety; and words such as ‘should’, ‘would’, ‘expect’, ‘hope’ and ‘need’. They are also more likely to use sex-related words and use them negatively.
