Facebook Knows You Better Than You Know Yourself










Privacy is dead. Big data is ubiquitous. There’s no escaping from the machine, and the machine knows all. So goes the common messages of doom and disarray every time we see a new report showing the amount of personal information being broadcast online for all to see. And the latest is no different – though admittedly, this one is a doozy. A group of researchers from the University of Cambridge and Stanford University have found that insights gleaned from Facebook data may be able to predict a person’s personality and preferences better than their colleagues, friends or even their partners are able to. Their testing even showed that, in some cases, the data knew people better than they knew themselves. Such findings are bound to spark concern – maybe Elon Musk is right and the days of SkyNet and robot overlords are closer to reality than we’re even aware.

This research has already raised the hackles of internet privacy advocates – and by all means, there is a very valid basis for privacy concerns, but one of the main contenders amongst common privacy worries is that such information might fall into the hands of advertisers who’d be able to target people with personalised ads. For me, that’s not so much of a concern. I mean, advertising’s everywhere, right? The average person’s exposed to more than 250 ads per day (and that’s a low estimate). No matter how you look at it, ads are a fact of modern life – so why not be shown ads that are relevant to your interests, for things you actually might want to purchase?

The Power of Like-ness

The study was conducted by correlating the personality traits and Facebook ‘Likes’ of the 86, 220 total participants. The first step was to have each person complete a 100 question test which determined key behavioural leanings. From there, the researchers inputted the results of those tests along with each person’s Facebook ‘Like’ profile, giving them a clear cross-section of people’s preferences, matching behavioural data with Facebook persona. From this, they were able to model specific elements, as noted in this piece by Issie Lapowsky from Wired:

If, for instance, several people who liked Snooki on Facebook also scored high in the extroverted category, the system would learn that Snooki lovers are more outgoing. The more “Likes” the system saw, the better its judgment became.”

On a small scale, such results might not mean much, but at such large volume, the results become pretty indicative, so much so that, as noted, when friends and family members were tested on their knowledge of the test subjects, they were not as accurate as what the researchers could glean from Facebook data, matched against the participants own responses.

A Gold (Data) Mine

This study highlights the amazing range of insights we now have available to us. Privacy concerns aside, the benefits of such analyses are far-reaching – the possibilities for the early detection of health problems, the ability to better detect and respond to psychological distress, the opportunity to help guide people towards better career and lifestyle choices specific to their personal traits – these are just a few of the major potential benefits of big data and integrated learning. And then there’s the possibilities for marketing. The dark arts, the elephant in the room in the wider big data conversation. While, of course, such information can be mis-used, there are also significant benefits of connection, for linking people to products and services relevant to them, at the right time that they need them. Yes, it can be creepy, especially when you see those side-bar ads for that thing you just wrote about in an e-mail, but the opportunity is there to build a more collaborative commercial system that’s more responsive, more efficient, and functions at a more optimal level for both business and consumer.

If Facebook data can determine the specifics of your personality and preferences, imagine how powerful that would be in helping a small business find the right audience and get itself started? Right now, you could build a profile of all of your customers, narrowed down to those who’ve made a purchase to eliminate the ‘observers’ in your community, and you could establish a clarified persona of the people you want to target, based on their listed preferences. Essentially, this is what Facebook’s ‘Lookalike Audience’ feature already does, the data points they’ve used in this study would be the similar reference points to the ones they use in that algorithm, helping you find the right people – if you weren’t sure of the potential of that option (or that option’s existence), these results might make you think twice. But even without access to the whole Facebook dataset or their team of expert analysts finding patterns and correlations, you can conduct your own audience research, you can establish similar insights on a smaller scale.

If Facebook Likes can tell you who a person is, you have to believe the data you can glean from an engaged community is worth the effort of building it in the first place. The power of social media data should not be ignored, it’s the most valuable audience insight tool we’ve ever had access to. Used well, and used ethically, it’ll likely becomethe key resource in your marketing and outreach efforts. The trick is to know what to look for, know where to find it, and also, how to rationalise it to maximise the benefits for both you AND your customers.
