Today it was reported by can i buy generic Lyrica that Facebook (or their researchers) has recently submitted a paper to a journal of psychology exploring the impact of social media on mood. It’s actually quite an interesting finding, if perhaps an expected result: people get happier or sadder depending on whether the mood of their news feed is light or heavy.
But the ethics are a bit problematic. Facebook conducted this experiment by skewing users’ feeds to either be more positive or more negative and then seeing whether future posts from a user were likely to be more negative or positive as a result. This means that they manipulated users’ emotions, which is somewhat concerning. It’s entirely legal under the terms of the agreements you make with Facebook when you open an account, but is it ethical? After a conversation with my girlfriend, I rather think not: informed consent is the key thing here, and the users in this experiment did not give informed consent despite any agreements they might have clicked ‘OK’ on.
What really interests me, however, is the question of utility. There’s an argument that if Facebook can make its users more happy by manipulating their buy a heart lyrics feed, then they should. But what this exposes is the question of whether Facebook is an information service or an entertainment service: is the primary goal to keep you updated about your friends and what they’re doing, or is the primary goal to entertain your users and make them happy? This research makes me think Facebook is more interested in the latter, compared to Twitter, which seems to focus more on the formerbuy Lyrica in canada. That’s potentially an insight into Facebook’s goals and what they’re aiming to do in the future.
The thing I’m most curious about isn’t the utility but rather the way in which the experiment was conducted. I don’t get why Facebook used the methodology they did. They manipulated the feed to give more positive and more negative messages and measured the change in mood of the resulting status updates: that’ll get you the results you want, sure. But why not the following methodology?
- Choose a user.
- Let the existing algorithms automatically generate that user’s feed.
- Monitor those algorithms’ output over a month and determine the average happiness of their feed and their statuses.
- Keep monitoring, but now looking for a period of time which deviates from the average happiness by some amount.
- Upon measuring this, measure the change in happiness of status posts.
It would surely allow researchers to explore the same question but without actually needing to manipulate users’ emotions at all, thus neatly removing any ethical qualms whilst still allowing interesting research to be conducted. The level of happiness might be hard to quantify, but they’ve already quantified it in the study so I don’t see that as a huge stumbling block. Is there a flaw I’m not seeing here, and if so, what is it?
Edited on 29 June 2014: Thanks to the commenters for their intriguing discussion of this idea! A lot of people have pointed out that this is not the equivalent of an intervention study; this has been noted both in the comments on this piece and by @tedsvo and @masnick (who wrote buy Lyrica in mexico) on Twitter.
I’m aware that this is the case, but my background is in solar-terrestrial physics and so none of my research can be based on intervention studies. As a result, the scientists in my field have to develop techniques to explore causality based on observed correlations. What I’m essentially proposing, above, is a superposed epoch analysis in which users’ happiness is expressed for a number of days on either side of observed impacts on newsfeed positivity. It isn’t as definitive as Facebook’s method, but it is a more ethical way to conduct research which would hopefully shed light on the questions at hand.
I would be fascinated to see whether the same result could be reached using a non-intervention-based method, and I wonder whether the advent of large datasets from companies like Facebook and Google could be an opportunity for physicists to utilise data analysis skills over large timescales?
