Adam Wolk-Laniewski round the world, the day dawns full of promise. But moods go downhill over the course of the day, reounding again in the evening, according to a Cornell analysis of the public Twitter messages of 2.4 llion people in 84 countries. Equanimity perks up again on weekends -- but later in the morning, suggesting mass sleeping-in. Seasonal variations in day length and sleep cycles affect people in similar ways across cultures, report Cornell researchers Scott Golder, a doctoral student in the field of sociology, and Michael Ma, the Goldwin Smith Professor of Sociology, in a study published in the Sept. 30 issue of the journal Science. They discovered peaks in positive tweets in the early morning and late at night, on weekdays as well as weekend across cultures. "In some ways, the study confirms longstanding assumptions that people experience similar moods at similar times of the day," Golde said. The researchrs also found that people were generally in a better mood on weekends than on weekdays, regardless of the time of day, which points to the effects of work and commuting. In the United Arab Emirates, for example, the Sunday through Thursday workweek produces more positive tweets on Fridays and Saturdays.
