U.S. Mood Measured Through Twitter, 2006-2009

A group of researchers have published a simple word analysis of 300 million tweets (you know, those short, 140 character-maximum status updates from individuals) from Twitter and discovered something amazing — people are happier on the weekends, and before and after work. Yes, that’s right — people are happier when they are not working!

It took three researchers from Northeastern University and two from Harvard Medical School to arrive at these stunning conclusions.

Now, since researchers didn’t actually look at 300 million tweets individually, the mood of each tweet was inferred using the ANEW word list — Affective Norms for English Words — a word-rating system that gives normative emotional ratings for English language words. These kinds of analyses are indirect and rough measurements — they can only note very large trends because they are not necessarily reliable.

  1. Wow-what a surprise-people are happier on weekends than weekdays.

    I realized I’m starting to be disappointed in hearing about studies similar to this one.

    There are so many losing their homes, cannot obtain employment, and have no health care. I know research leads to positive changes-but some of the stuff produced sure isn’t helping anyone right now.

    People need help-why do so many have $$$$$ to spend on this crap while so many go without health care? If I recall correctly, wasn’t Harvard recently criticized for offering poor mental health care to students?

  2. Actually, there is something interesting in the results: People in California and Florida are happier than others in the US, even when compared to other states on the coasts. Oklahoma never makes it past white, nor does Texas, nor most of the midwest.
