Is Happiness Declining? Twitter Analysis Says It Is

0 comments
From what celebrities are doing at any given minute to the little things that irk ordinary people, there’s a lot to learn from Twitter.
Researchers at the University of Vermont used the social media service to learn about people’s happiness and, through an analysis of billions of words used in millions of tweets, determined that societal happiness is on the decline.
Over a period of three years, scientists gathered 46 billion words found in tweets by 63 million users around the world and, with the help of a web site, determined the “happiness” of the 10,000 most common words in the English language.  ”Laughter,” for instance, got an 8.5 on a scale of one to nine, and “food” came in at 7.44. “Truck” was a better-than-average 5.48. “Greed” registered a 3.06;

“terrorist,” 1.30.
