Facebook Figured Out My Family Secrets, And It Won't Tell Me How (gizmodo.com)

Kashmir Hill, reporting for Gizmodo: Rebecca Porter and I were strangers, as far as I knew. Facebook, however, thought we might be connected. Her name popped up this summer on my list of "People You May Know," the social network's roster of potential new online friends for me. [...] She showed up on the list after about a month: an older woman, living in Ohio, with whom I had no Facebook friends in common. I did not recognize her, but her last name was familiar. My biological grandfather is a man I've never met, with the last name Porter, who abandoned my father when he was a baby. My father was adopted by a man whose last name was Hill, and he didn't find out about his biological father until adulthood. The Porter family lived in Ohio. Growing up half a country away, in Florida, I'd known these blood relatives were out there, but there was no reason to think I would ever meet them. A few years ago, my father eventually did meet his biological father, along with two uncles and an aunt, when they sought him out during a trip back to Ohio for his mother's funeral. None of them use Facebook. I sent the woman a Facebook message explaining the situation and asking if she was related to my biological grandfather. "Yes," she wrote back. Rebecca Porter, we discovered, is my great aunt, by marriage. She is married to my biological grandfather's brother; she met him 35 years ago, the year after I was born. Facebook knew my family tree better than I did "I didn't know about you," she told me, when we talked by phone. "I don't understand how Facebook made the connection." How Facebook had linked us remained hard to fathom. My father had met her husband in person that one time, after my grandmother's funeral. They exchanged emails, and my father had his number in his phone. But neither of them uses Facebook. Nor do the other people between me and Rebecca Porter on the family tree.

      Facebook says the huge psychological experiment it secretly conducted on its users should have been âoedone differentlyâ and announced a new set of guidelines for how it will approach future research studies.

      In a blogpost on Thursday, Mike Schroepfer, chief technology officer, said the company had been âoeunpreparedâ for the negative reactions it received when it published the results of an experiment in June.

      Facebook published the results of a 2012 study in the Proceedings of the National Academy of Sciences. Unbeknown to users, Facebook had tampered with the news feeds of nearly 700,000 people, showing them an abnormally low number of either positive or negative posts. The experiment aimed to determine whether the company could alter the emotional state of its users.

      Phone number is needed to provide extra layer of security for your account. Also to ensure Facebook that your account is real, reducing possibility of marked as suspicious. You can always hide the phone number from others via about section.

      I had some weirdness with Linkedin when it started sending me adverts and articles relating to living with someone with terminal cancer. Turns out one of my parents cats had colon cancer and they didn't want to tell me. So I would guess that the algorithms use a kind of diffusion process. Every person has their own unique ID number, then all bits of information about them get linked to that ID number. Each person also had links to other people. Then deductive logic can be applied. If someone is a skydiver, then all those links can be updated to have "knows someone who is a skydiver". Maybe this gets weighted by the number of people they know or how many links it takes.

Other examples are products that we are interested in, shows that we like, churches and other organizations we attend, what times we are usually awake and surfing the web, where we've traveled to, etc.

      It would be interesting to explore whether an app or extension could be created that enhances privacy by obfuscating all of that information - employing a smart bot to use both the web and apps in semi-random fashion.

      I say "semi-random" because I think it would be more difficult to discern truth if the things it was looking up, places it was pretending to go, etc. were reasonable for someone living in my area and fitting into society in at least a similar fashion. It would also need to do these things in a fashion that looks like a human. i.e. people don't visit a hundred sites at once, they read along the way. The timing needs to be right at the least.

They periodically suggest I may wish to know people who aren't related to me in any way, they just happen to know somebody I know. It could just be that maybe the author and this aunt both like, say, the same TV show and follow it on Facebook and that led to a connection that was pure luck and had nothing really to do with a family relationship.

Facebook didn't find them at all. And to show you how "nice" that side of my family is, both rejected my friend request on Facebook. The author probably doesn't know how incredibly lucky they were to get a message through to the aunt. If you aren't friends with someone on Facebook and send them a message, by default you go to a spam part of Facebook messages that doesn't open by default and the vast majority of users never look at because they don't know it exists. I've also found cousins on the other side of my family who did accept my friend request and in no way did Facebook help us to find each other. It actually took the blind luck of a cousin I am in touch with finding an entry on Find A Grave that another cousin none of us knew how to contact had placed there for a common relative. The Find A Grave listing had an email address that we used to ultimately get back in touch with 6 family members we'd all lost track of. So yeah, I am not convinced that Facebook really knows the author's family connection as much as they just suggested a connection for another reason and it was just pure lack that there was a family connection.
