A survey carried out on the microblogging site Twitter has found that people are more cheerful in the morning and their mood goes down as the day progresses, before rebounding in the evening.
The study analyzed more than 509 million tweets from 2.4 million users in 84 countries between February 2008 and January 2010 and found that people are happier from December to mid June and bad news, even if it happens to complete strangers, tend to get the mood down.
The study was carried out by researchers at Cornell University who found that majority of the Twitter users liked Cheerios rather than Frosted Flakes and preferred bacon to sausage. Lead researcher Scott Golder said that Twitter offers a great opportunity for social scientists to study societies more closely.
Writing in the report, published in the journal Science, Golder said, "We now have the ability to view societies at a massive scale using the Internet. This will open up opportunities for social scientists."
