Carolyn Y. Johnson reports:
It started as a simple term project for an MIT class on ethics and law on the electronic frontier.
Two students partnered up to take on the latest Internet fad: the online social networks that were exploding into the mainstream. With people signing up in droves to reconnect with classmates and old crushes from high school, and even becoming online “friends” with their family members, the two wondered what the online masses were unknowingly telling the world about themselves. The pair weren’t interested in the embarrassing photos or overripe profiles that attract so much consternation from parents and potential employers. Instead, they wondered whether the basic currency of interactions on a social network – the simple act of “friending” someone online – might reveal something a person might rather keep hidden.
Using data from the social network Facebook, they made a striking discovery: just by looking at a person’s online friends, they could predict whether the person was gay. They did this with a software program that looked at the gender and sexuality of a person’s friends and, using statistical analysis, made a prediction. The two students had no way of checking all of their predictions, but based on their own knowledge outside the Facebook world, their computer program appeared quite accurate for men, they said. People may be effectively “outing” themselves just by the virtual company they keep.
