Twitter shows how the world is feelingWeekends are happier times than weekdays, right? That association holds up in new research published in the journal Science that used Twitter to gauge the moods of millions of people. Researchers at Cornell University looked at tweets from all Twitter users who created accounts between February 2008 and April 2009, weeding out those who tweeted fewer than 25 messages. In total, they looked at 509 million messages written by 2.4 million people. Then they matched words from those tweets to an established word list that psychologists use to gauge positive and negative moods. They found that people tend to wake up in a good mood, which progressively worsens over the course of the day, but then picks back up from dinnertime to bedtime. Before you go blaming your job entirely for bad moods, consider that the researchers observed a similar pattern both weekdays and weekends, with the morning freshness deteriorating and then a second wind of good mood around dinnertime. So maybe there's something biological going on relating to circadian rhythms and sleep. On the other hand, overall mood is better during the weekends. In fact, weekends are happy times no matter what days happen to form your weekend. Most people in the United States have off from work on Saturdays and Sundays, and their mood as reflected on Twitter is heightened during that time. In the United Arab Emirates, weekends are Fridays and Saturdays, so Emirati people show good moods on those particular days. Also, generally people sleep later on the weekends. "It is possible that when you are being woken up by the alarm clock, it interrupts your natural rhythm in a way that doesn’t happen when you wake up naturally," said study co-author Michael Macy, sociologist at Cornell University. Tweets also reveal how moods change seasonally. It appears that the amount of daylight doesn't matter so much as whether the days leading up to it were longer or shorter. As the summer solstice approaches, and the days get longer, mood is higher on average than when daylight hours decrease, as the winter solstice approaches. Researchers saw these trends across Twitter users in 84 countries, suggesting there is something universal related to circadian rhythms, as well as the effects of environmental stressors like the workday, said lead author Scott Golder. There's also the factor of when the sun rises and sets in your locality, says Macy. "Culture interacts with our biological patterns to produce the changes in mood that we are able to observe using these data from Twitter," Macy said. But tweets reveal more than just moods. Golder has launched a website called timeu.se where you can explore more behavioral results from the Twitter dataset. For instance, worldwide people seem to eat bacon (red line) more than sausage (blue line), although both are eaten at similar times of the day. 
Beyond the results of the study, the methods represent a "game changer" for the future of this kind of fieldwork, Macy said. "It’s all a playground for all the social sciences and the behavioral sciences," Macy said of social media.

Lol, real scientific. I hope no-one buys into this. People selectively twit. There's absolutely no way to measure the mood of the world, just people that are on twitter at any given moment.
According to Annie Kaune's article on behavior and human computer interaction
People actually tweet whether they are eating bacon or sausage?
tweeting is all about randomness. It's much different then facebook. I wouldn't be surprised if I had a bacon tweet or two!
It's amazing how people let others control their time. Why would anyone be interested in someone else eating bacon. Unless you're 15, of course.
If Amanda Knox spends another week in the Italian prison I think that every civilized nation should stop buying any Italian products including wine! Hurt them where it would hurt the most "Their pocketbooks" LET HER GO AS THE EVIDENCE SHOWS!
What does that have to do with this article? Please stay on the topic.
Really? Really?! Are you one of those people that believes sticking absolutely random comments in topics having NOTHING to do what you are "taking a stand for" is actually going to do anything? Maybe you feel it satisfies your moral conscience; that you are doing some good for someone, somewhere? You're not. Whether this girl is innocent or not is irrelevant here, in this topic. This is a topic about Twitter, not Twits. Go preach somewhere else. Maybe a street corner where people will take you a bit more seriously?
This app actually tries to do exactly what you descrive here, the data is inputed from beginning within happy/unhappy channels.

Cornell seems to be letting morons in these days – anyone one with 1/10th of a brain would know that this is a useless survey because it does not encompass non tweeting people. A shame anyone funded these idiot researchers
Regardless of the type of survey, someone will always be left out, whether intentional or inadvertent. You cannot discredit the survey based upon that solely. I find this to be an interesting interpretation of what people display on social media and how that relates to social behaviors.
The survey itself does have a valid point. Using this data they have enough people to show it's not random. They have different ages, gender, incomes, counties, lifestyles, and other variables I have not listed to add to the independent variables. As an added bonus they don't have to worry about bias from people worried about what the researchers will think. Anyone who has taken a sociology course will know this.
Did the pork have any metal pieces in it?
WOW!!! ... watching, disecting and monitoring our conversations...hmmm
I want to see a similar study using CNN soundoff responses
it is a biased sample (that is to say, certain demographics are more likely to use twitter than others) but a useful one nonetheless. At the least, it provides material for finding possible trends to check for among the greater population.
Attention seekers unite!
2.4 million is hardly a representative sample of the world population. Furthermore the model us biased towards younger age groups.
Twitter if for kids, i.e., those with time on their hands with narcissistic tendencies.
No, Twitter shows how the people that post to it feel, most of the world doesn't use that service. Few people have anything important or relevant to say, and just being online doesn't make it anymore interesting or a gauge to see how people (or the world) feels.
The first thing to know about any statistic is you can get the numbers to say what you want. Secondly, there's no way possible to survey all the people, all the time. Therefore, researchers use a sample of the population to measure the whole population. Of course there will always be people not represented. The study gives a general indication of how people all over the globe may feel during the day by using their own thoughts expressed by their own words.
Everyone see the picture with this article? That represents who should be using twitter. It's a toy for kids. Grow up, folks. People don't really care about you that much, but don't have the heart to tell you.
I don't mind my job. it's some of the people at work that are the ones put in place to make sure your five days (when I would rather be home) make it so miserable at times!
Anyone from the top man to those middle managers who would sell their mothers and first born for power. Then karma happens and they are the ones who loose out in the end.
This is all based on the assumption that a Twitter user is posting 24/7, but according to my research people actually sleep.
I'm taking a dump in the stockings of all these "scientists" involved with this study.
Behavioral science seems like fairly non-toxic subject for now... but I wonder, given mankind's thirst for power, how long it will take before the behavioral sciences become socially toxic in their use. My guess is about a day or two.
Certain kinds of people tweet, people that are self centered and think the rest of the world cares what they are doing every second of the day and people that are obsessed with following celebrities because they don't have a life or are incapable of independent thought. Neither of those two types of people speak for the rest of the world. Just look at the two girls in the picture, if they are the average person we are all in trouble............
I'm awake, I'm alive! I'm so happy!
oh wait, I gotta go to work now. I am so depressed.
I better put this on twitter, for the sake of science.

DONT BOTHER TRYING TO DO A SURVEY ON WHAT A VERY MINUTE PART OF THE GLOBAL POPULATION WITH A FOOD OPINION. HARDLY SCRATCHES THE SURFACE WHEN IT COMES TO THE NATURE OF PEOPLE YOU'VE BEEN BRAINWASHED. I LOVE THE FALL AND WINTER BY THE WAY WITH ALL THE FOOD CONTAMINATION, DONT ASSUME WHAT WE WILL BE EATING AT ANY TIME OF THE DAY WITH THOSE HARD COLD FACTS. HAVE A NICE DAY!

Think back for a most successful parcel of content. Now think of all the other methods you might send this information. Would it not work well as a video clip? As an Info-graphic? As a longer white paper or guide? As a far more sophisticated set of shorter articles?
