Facebook says it isn’t an echo chamber. But is it a hall of mirrors?

Putting aside for a moment from the actual questions the Facebook Data Team asked and the answers they got, both of which are interesting (so I will try to get to grips with them – in a later post),  I think the most surprising thing about this study is the fact that Facebook publicly used itself as an experiment,  and nobody blinked.    What they did in the study was only a tiny, weensy bypass operation.  (The experiment involved  withholding some newsfeed items from its users that they would normally have seen as result of the operation of the service.)    But it was surgery none the less.

My own private speculation is that Facebook experiments on itself all the time, and then quietly gets on with applying the lessons it learns by doing so.   But the Data Team’s world-facing work is usually correlational and observational rather than directly experimental.  So this work is different: here, they did tweak around with Facebook, and they did publish their results.  And I am surprised that nobody seems to be interested in that fact.  I don’t have an issue with the fact they did it.  In fact,  I’d be a bit disappointed if they didn’t.  But then I’m an experimentalist by background.

Don’t get the wrong idea: I do care whether I see stuff that’s sent to me.   When I get the post delivered from the postman each morning I don’t expect him to randomly hide some of it from me just to see what would happen.    Interestingly I have heard more than one story in which it turns out that is just what (a few lone and deranged) postal workers sometimes actually do.   But although this isn’t unheard of, at least as an urban myth,  it’s not what I expect, and were the behaviour to be discovered, I would expect it to be stopped.   Ignoring my post is my job, not my postman’s.

But my view of my Facebook Feed is different.  My understanding of my Feed is that it is cooked up according to a secret sauce recipe which, although it isn’t exactly to my personal taste, represents Facebooks’ best efforts at optimising something of interest to it.   And I believe the recipe for this sauce is constantly evolving, although the brand remains the same.   So to find there has been a tiny systematic tweak made to it, whereby some information was hidden for some people when it would normally have been displayed,  is neither a big shock, nor a bad one.

What surprises me about it is that it seems to have been so generally unsurprising.  I have a few different theories about this:

1.  the Eric Reis theory

The Lean Startup ideas of Eric Reis have become so pervasive and “baked into the DNA” of our culture that everyone who thinks about the matter expects to become part of some massive multivariate test whenever they encounter any application or platform.

2.  the filter bubble theory

Nobody who would potentially have been offended or puzzled by having their NewsFeed tweaked around with actually understood what was happening.

Here are some screenshots I took this morning about the relative numbers of people who publicly lauded the research summary, versus the full research article.

The score is as follows.   There were over 5,000 social actions performed on the summary.   And 165 on the article itself.

3.  the common sense theory

The change made was so non-material in its potential and actual impact that nobody in their right minds could possibly make a big deal of it.

So, no shortage of theories.  But I’ve no idea which one is right.   Do you?    My guess about the recipe is:  20% Theory 1, 60% Theory 2, and 20% Theory 3.

The highly munchable and crunchable soundbite about the study, distributed with the summary ,  was that the research demonstrates that Facebook is not an echo chamber.   This meme has bounced around languidly, albeit dominantly,  following the release of the research.   I believe that the research, while interesting, does not actually warrant this conclusion directly.   But what the research does demonstrate, by its very existence, is that whether or not Facebook is or is not an echo chamber, for sure it sometimes acts like a hall of mirrors.

  1. Heya this is kinda of off topic but I was wanting to know
    if blogs use WYSIWYG editors or if you have to manually code
    with HTML. I’m starting a blog soon but have no coding knowledge so I wanted to get advice from someone with experience. Any help would be enormously appreciated!


    • check out wordpress.com which is what this blog uses. there is a wysiwyg editor and if you want you can also get an html view. there is a choice of styles/themes you can use for free. there is also an active support community. enjoy!
