The sheer volume of data Facebook has on you is difficult to comprehend, which stimulates it incredibly creepy and ripe for conspiracy theories
Last week, Facebook issued yet another denial that the company eavesdrops on its users to target them with adverts.
” Just not true ,” said Rob Goldman, the company’s head of ad product, in response to an open query from podcast Reply All.
After used to describe the refusal, my inbox almost immediately began filling with missives from people insisting that Facebook must be lying.
One person wrote they never drink wine, but a friend of his mentioned a wine delivery service to his wife and he saw the ad the next day. Another insisted he had proved it to his friends once before. A third said she had gratified many users where eavesdropping was ” the only option” for explaining why they had received the adverts they had.
What is it about this conspiracy hypothesi that makes it the most persistent in tech?
Part of the explain is that it’s really very hard for Facebook to prove that it isn’t doing what it’s accused of. The company’s apps are widely have permission to access the camera and microphone, because people cinema video and take images use Facebook, Instagram, WhatsApp and/ or Messenger.
While you can tell from looking at the traffic to and from your phone- or even just from your mobile data usage- that Facebook isn’t uploading a livestream of everything you say and do, there are always other possibilities. Perhaps it’s doing the processing on-device? Or merely listening for key phrases? Or uploading everything in a burst when you get on wifi?
Facebook doesn’t help itself. It has a long history of pushing the boundaries of what’s acceptable in order to increase ad revenue, from profiling the” ethnic affinity” of users( totally different from racial profiling, it swears) to merging user data regarding WhatsApp with its main service. With that history, it’s not a giant leap for many people to simply assume Facebook is lying in its denials.
But the sheer wealth of proof many are able to summon to support the hypothesi also demonstrates another element to its perseverance: the true nature of algorithmic ad targeting is still not widely known.
The sheer volume of information the social network has about a typical user is difficult to comprehend. It logs every action of you and your friends, and a substantial proportion of browsing off-site thanks to its Facebook share button. It also has information provided by friends, such as that ex who uploaded her address book containing your phone number and your embarrassing teenage email address, permitting Facebook to work out that you know that high-school friend who you haven’t seen for a few years but who still has your older contact details.
And, apologies, but you aren’t that special. If you have had a dialogue about a particular topic, then it’s unlikely you are the only one. While your dialogue may have been held in person, a lot of others will have happened on Messenger or in Instagram remarks. It’s not a stretch to assume that if a lot of London-based humen aged 25 to 34, whose interests include stadium boulder and panel shows on Dave, start talking about buying tickets to ensure the Foo Fighters, then other London-based humen aged 25 to 34 are probably solid targets for the same advertising.
