Breaking: When people are in a bad mood, their twits reflect it.
Drawing on messages posted by more than 2 million people in 84 countries, researchers discovered that the emotional tone of people’s messages follows a similar pattern not only through the day but also through the week and the changing seasons. The new analysis suggests our moods are driven in part by a shared underlying biological rhythm that transcends culture and environment.
The report, by sociologists at Cornell University in New York and appearing in the journal Science, is the first cross-cultural study of daily mood rhythms within the average person using such text analysis. Previous studies also have mined the mountains of data pouring into social-media sites, chat rooms, blogs and elsewhere on the Internet but looked at collective moods over time, in different time zones or during holidays.
