Alarm Bells for Privacy – Facebook ‘likes’ predict personality

The findings should “ring alarm bells” for users, privacy campaigners said.

The study used 58,000 volunteers who alongside their Facebook “likes” and demographic information also provided psychometric testing results – designed to highlight personality traits.

The Facebook likes were fed into algorithms and matched with the information from the personality tests.

The algorithms proved 88% accurate for determining male sexuality, 95% accurate in distinguishing African-American from Caucasian-American and 85% for differentiating Republican from Democrat.

Christians and Muslims were correctly classified in 82% of cases and relationship status and substance abuse was predicted with an accuracy between 65% and 73%.

The links clicked rarely explicitly revealed these attributes. Fewer than 5% of gay users clicked obvious likes such as gay marriage, for instance.

Instead, the algorithms aggregated huge amounts of likes such as music and TV shows to create personal profiles.

Google Contacts Nightmare

So a slight problem recently with contacts.
I use a number of tools and web apps in my daily life to keep things organised beacuse I work for myself I use a number of machines in a number of offices so it’s easier to rely on web applications for some tasks.

30 boxes (30boxes.com) for a calendar as this also allows my partner to add events and we can keep track of what nights we have free for stuff which is nice.
Gmail (gmail.com) for email as it’s usually reliable and has heaps of storage space and I like the search
plaxo (plaxo.com) for keeping my contacts up to date
linkedin (linkedin.com) for business contacts
mobile me (me.com) because it came free with my iPhone and works with my MacBook address book

The problem I have now is syncing al the data.

This used to be easy as every now and then I would sync with plaxo to my work machines and that would pick up new contacts and I would dump them into Gmail manually. Not too painful and simple.

Now though the iPhone sync has got the better of me. Gmail has a whacked-out idea of contacts management in that email addresses are automatically added to your contacts list each time you use the reply, reply to all, or forward functions to send messages to addresses not previously stored in your contacts list. Sounds great in theory. In practise I don’t actually know a lot of those people and I may not want them in my contacts list.

iPhone has imported contacts from Gmail bringing all this random data and that has synched with mobile me and now my phone has 1800+ contacts only around 300 of which I actually added myself.

Google what are you thinking adding all these people to my contacts list without asking me?
Apple what are you doing allowing me to sync with data that is so different from my original set without setting off alarm bells somewhere.

Gah!
