In 2012, Facebook Altered Content To Tweak Readers' Emotions

The Atlantic reports that two years ago, Facebook briefly conducted an experiment on a subset of its users, altering the mix of content shown to them to emphasize content sorted by tone, negative or positive, and observe the results. From the Atlantic article: For one week in January 2012, data scientists skewed what almost 700,000 Facebook users saw when they logged into its service. Some people were shown content with a preponderance of happy and positive words; some were shown content analyzed as sadder than average. And when the week was over, these manipulated users were more likely to post either especially positive or negative words themselves. This tinkering was just revealed as part of a new study, published in the prestigious Proceedings of the National Academy of Sciences. Many previous studies have used Facebook data to examine “emotional contagion,” as this one did. This study is different because, while other studies have observed Facebook user data, this one set out to manipulate it. At least they showed their work.

    There are laws governing obtaining informed consent from humans before performing psychological experiments on them. I doubt that a EULA can override them. This should be interesting...

      I don't think this is about whether Facebook had a legal right to do this, but more on that in a minute. It's more about whether it was ethical on their part. Regardless, I think it clearly was not ethical for the researchers to do this study without getting the approval of the users who took part in the study.

      Getting back to the legal issue, every site or app has a Terms of Services agreement. Does FB's TOS say that you might be randomly placed in a A/B test used for academic research purposes? If they don't, it seems to me that could be a legal issue.

      From a legal standpoint, for an activity to be considered "research", it must be "designed to develop or contribute to generalizable knowledge". http://www.virginia.edu/vpr/ir...

      When a website uses A/B testing to improve its own internal operations, it's seeking to privately develop limited knowledge on its own operations, rather than general knowledge. This puts it outside the scope of US federal regulations on research, which have been narrowly crafted to avoid regulating commercial activities like these.

      Given these criteria, Facebook was surely engaged in research.

      There are laws against assault, bullying, and so on. The positive spin in innocuous but the negative spin is not.

      With 700 000 potential victims, the numbers are against them because when your sample size is that large outliers are the rule and not the exception.

      The risk of copycat suicide for example should have been obvious to those conducting this study.

    This is quite interesting research that should never have been done. I am rather surprised that the National Academy published the results of a study which violated multiple ethical guidelines put in place to protect human subjects. Did Facebook track the number of suicides in the 700,000 sample? Was the rate of those given a sadder than average stream have a higher or lower rate? Do the Facebook researchers address the ethical questions posed by performing such an experiment at all?

  4. Facebook encourages posing. by Qbertino · · Score: 4, Interesting

    I see it in my self, on the rare occasions that I actually post, which is roughly 5-10 times a year and I see it with others whenever I go online to browse a little in the posts of the people I'm connected with ... called "Friends" (Fingerquotes!) on FB:

    Facebook and other "social networks" encourage posing. No two ways about it.

    If you get all worked up and batter your self esteem just because somebody posted himself in cool poses or on some event that you "missed out" on ... I get this a lot, since I'm only on FB for my tango dancing connections, a pastime where posing sometimes actually is part of the game. Actually knowing the person behind a neat facade on FB does put things into perspective.

    Bottom line:
    People shouldn't get more attached to these things than it is good for them. If this neat little stund by FB shows them that, then all the better.

    My 2 cents.

    What actually disturbs me more is: why should they do this? The answer is simple: They want to determine the most effective non-obvious way of creating filter bubbles to make the user feel well and stay longer.

    It is so-to say a "second order filter bubble", i.e. the use of a positive feedback mechanism.

    It's called the Common Rule, although it generally only applies to federally funded research. There is some evidence that this study was in part federally funded. I think there are serious questions about whether a click-through agreement meets the standards of informed consent.

    Although the study was approved by an institutional review board, I'm surprised, and the comment from the Princeton editor makes me wonder how well they understood the research design (or how clearly it was explained to them). This would never have gotten past my IRB.

    1. Right before an election, all posts favoring candidate X or the political views of party X were promoted to the top of everyone's feed and given 20 extra fake "Likes", while posts favoring the opposition are demoted and de-liked.

    2. Phrases in posts favoring candidate X or the political views of party X are subtly "edited" when the appear in everyone else's news feed to be more positive (e.g., "like" to "love", "good" to "great"), while phrases in posts favoring the opposition are given the reverse treatment and sprinkled with misspellings.

    3. FB users with a tendency of opposition to party X have random fake posts/comments from them appear in other's feeds only, in which they insult their friends' baby pictures, make tasteless jokes, and vaguely threaten supporters of party X to "unfriend me if ur so lame u can't take the TRUTH, lol".
