Facebook has changed its privacy settings this January. For Europeans, the changes have come into effect on January 30, 2015.
Apart from collecting data from your contacts, the information you provide, and from everything you see and do in Facebook, the new data policy enables Facebook to use your GPS, Bluetooth, and WiFi signals to track your location at all times. Facebook may also collect information about payments you make (including billing, shipping, and contact details). Finally, the social media giant collects data from third-party partners, other Facebook companies (like Instagram and Whatsapp), and from websites and apps that use their services (websites that offer “Like” buttons and use Facebook Log In).
The result? Facebook will now know where you live, work, and travel, what and where you shop, whom you are with, and roughly what your purchasing power is. It will have more information than anyone in your life about your habits, likes and dislikes, political inclinations, concerns, and, depending on the kind of use you make of the Internet, it might come to know about such sensitive issues as medical conditions and sexual preferences.
A closer look, however, might reveal the matter in a different light. Continue reading
Twitter, paywalls, and access to scholarship — are license agreements too restrictive?
I think I may have done something unethical today. But I’m not quite sure, dear reader, so I’m enlisting your energy to help me think things through. Here’s the short story:
Someone posted a link to an interesting-looking article by Caroline Williams at New Scientist — on the “myth” that we should live and eat like cavemen in order to match our lifestyle to that of our evolutionary ancestors, and thereby maximize health. Now, I assume that when you click on the link I just gave you (unless you’re a New Scientist subscriber), you get a short little blurb from the beginning of the article and then–of course–it dissolves into an ellipsis as soon as things start to get interesting:
Our bodies didn’t evolve for lying on a sofa watching TV and eating chips and ice cream. They evolved for running around hunting game and gathering fruit and vegetables. So, the myth goes, we’d all be a lot healthier if we lived and ate more like our ancestors. This “evolutionary discordance hypothesis” was first put forward in 1985 by medic S. Boyd Eaton and anthropologist Melvin Konner …
Holy crap! The “evolutionary discordance hypothesis” is a myth? I hope not, because I’ve been using some similar ideas in a lot of my arguments about neuroenhancement recently. So I thought I should really plunge forward and read the rest of the article. Unfortunately, I don’t have a subscription to New Scientist, and when I logged into my Oxford VPN-thingy, I discovered that Oxford doesn’t have access either. Weird. What was I to do?
Since I typically have at least one eye glued to my Twitter account, it occurred to me that I could send a quick tweet around to check if anyone had the PDF and would be willing to send it to me in an email. The majority of my “followers” are fellow academics, and I’ve seen this strategy play out before — usually when someone’s institutional log-in isn’t working, or when a key article is behind a pay-wall at one of those big “bundling” publishers that everyone seems to hold in such low regard. Another tack would be to dash off an email to a couple of colleagues of mine, and I could “CC” the five or six others who seem likeliest to be New Scientist subscribers. In any case, I went for the tweet.
Sure enough, an hour or so later, a chemist friend of mine sent me a message to “check my email” and there was the PDF of the “caveman” article, just waiting to be devoured. I read it. It turns out that the “evolutionary discordance hypothesis” is basically safe and sound, although it may need some tweaking and updates. Phew. On to other things.
But then something interesting happened! Whoever it is that manages the New Scientist Twitter account suddenly shows up in my Twitter feed with a couple of carefully-worded replies to my earlier PDF-seeking hail-mary:
Yesterday, Charles Foster discussed the recent study showing that Facebook ‘Likes’ can be plugged into an algorithm to predict things about people – things about their demographics, their habits and their personalities – that they didn’t explicitly disclose. Charles argued that, even though the individual ‘Likes’ were voluntarily published, to use an algorithm to generate further predictions would be unethical on the grounds that individuals have not consented to it and, consequently, that to go ahead and do it anyway is a violation of their privacy.
I wish to make three points contesting his strong conclusion, instead offering a more qualified position: simply running the algorithm on publically available ‘Likes’ data is not unethical, even if no consent has been given. Doing particular things based on the output of the algorithm, however, might be. Continue reading
By Charles Foster
When you click ‘Like’ on Facebook, you’re giving away a lot more than you might think. Your ‘Likes’ can be assembled by an algorithm into a terrifyingly accurate portrait.
Here are the chances of an accurate prediction: Single v in a relationship: 67%; Parents still together when you were 21: 60%; Cigarette smoking: 73%; Alcohol drinking: 70%; Drug-using: 65%; Caucasian v African American: 95%; Christianity v Islam: 82%; Democrat v Republican: 85%; Male homosexuality: 88%; Female homosexuality: 75%; Gender: 93%.

Your password will probably be hacked soon, and how to (actually) solve the problem
The ancient art of password cracking has advanced further in the past five years than it did in the previous several decades combined. At the same time, the dangerous practice of password reuse has surged. The result: security provided by the average password in 2012 has never been weaker.
After the Twitter accounts for Burger King as well as Chrysler’s Jeep were recently broken into, Twitter apparently issued some advice to the effect that people should be smarter about their password security practices. So: use lots of letters and numbers, passwords should be 10-digits or longer, use a different password for every one of your online accounts and so on.
But this is nuts. Does Twitter know anything about how human beings actually work? Why do you think people reuse their passwords for multiple sites? Why do you think people select easy-to-remember (and easy-to-discover) factoids from their childhoods as answers to security questions?
