A valued network pointed me to a study by Facebook engineers investigating the diffusion of information through the Facebook social network with an experimental design! Yes. Experimental. The engineers randomly assigned nearly 250 million account holders (about half of the Facebook universe) to either receive a news story with a link from a friend or not. They then tracked how that information diffused through the network. Here’s a visual example of this t-test design. Click to enlarge.

Over a two week period, Facebook engineers would assign a Feed story with link to one person while randomly assigning two other people as a no Feed control. They did this repeatedly for two weeks over the 250 million selected accounts. They then tracked how the link got diffused through the friend networks.
Talk about a big data set. Huge, Jerry. Huge! Here’s the key finding. Click to enlarge.

Look again at those underlined values. Those randomly assigned to get a news story with URL in their feed showed a diffusion rate of 0.191% while those in control showed a rate of 0.025%.
Make sure you understand those little percentages. About two tenths of one percent diffused the link in the treatment condition. Thus, not even 1% of treatment people passed the link along. Not even one half of 1%. Barely 2/10 of 1 percent.
You can read the paper which I found at scribd.com. Given all the kinds of variables you can generate from a database this large, there’s more to the paper with lots of graphs, but they depend upon relative ratios rather than absolute effects. When you read that Outcome paragraph just above what probably struck you first was that huge relative risk ratio of 7.37. A Large RR would be 4.50, so this is absolutely Stupendous. The rest of the paper focuses upon those RRs while blithely skipping past the absolute diffusion rate. I remind you:
0.191%.
Please think like a maven here and not a muggle looking to move your 401k into the Facebook IPO. What’s the TACT here? What’s the Change you want from the Other Guy? Clicking on a link with a mouse and forwarding it to your Facebook network.
I’ve derided the social media TACTs before as the smallest units of communication you can create. Realize that this huge database quivers with the digital signals of the twitch, the click, the WATtap. That’s all they collected. A click.
Wouldn’t it be nice to see if this clicking behavior drove other behaviors? Like going outside of the Facebook network and using email, phone, or, gasp, face to face contact with other people about the information? Like making a financial contribution? Like volunteering. Like calling law enforcement with a tip? Like any real world, practical TACT?
And, shootfire, even fooling yourself briefly into thinking a click is as fundamental as kiss or a sigh as time goes by, what diffusion rate do you get?
0.191%.
Mavens, recall the fabulous Al Gore Facebook day. He made a great scarcity play with a one day extravaganza on Climate Change through Facebook and inveigled everyone to donate their network to the cause. How’d that go?
0.004%.
All folks had to do was click once and Gore’s machine would do the rest to then propagate the Gore message to your friends. One little click. And he got 0.004%.
Sure, we are mixing different variables in the comparison between Al Gore’s project and the one reported here. The Facebook experiment created a forced exposure while you have to go find Mr. Gore on Facebook that day. But we don’t have good research on social media, so we’re stuck doing these mental comparisons of apples and oranges, bytes and packets.
Social media has proven itself to be a toy, a pastime for killing time, phatic communication par excellence, a quick and easy way to be quick and easy, social without being sociable. Sure, imagine a big event like the assassination of JFK or the Challenger explosion and doncha know that Facebook and twitter would light up. But, so what? Where’s the TACT? What’s the Change in the Other Guy?
WATtapping clicks.
P.S. For what it’s worth, this paper apparently has not been published in a peer review source. It’s been submitted to the Cornell University Library at arXiv.org. I suspect it will get published in a good peer review outlet given the experimental design in a natural, if virtual, setting. My practical persuasion concerns remain. Facebook is a failure for Changing the Other Guys. Focus on the kiss and the sigh, mavens.
