One of your most paranoid fears is coming true. Right now, MIT computer science students are running advanced algorithms to determine who on Facebook is gay. According to an article in the Boston Globe, two MIT computer whizzes wrote up "Project Gaydar," a program that determines with alarming accuracy whether male Facebook users are gay or straight even if they don't announce it on their profile. The program looks at the gender and sexuality of the person's friends, which is public info on Facebook, to predict the sexuality of a specific individual. For some reason, it cannot determine who's a lesbian.
This is kind of funny in a "science confirms what we always knew" kind of way, but it's also TERRIFYING, right? In the future, your internet friends unintentionally out you to scientists. Also: how long until this become an all-too-quickly-used iPhone app?
