Although the researchers had no way to confirm the analysis with scientific rigor, they used their private knowledge of 10 people in the network who were gay but did not declare it on their Facebook page as a simple check. They found all 10 people were predicted to be gay by the program.Seems like there may be a correlation / causality issue- specifically, I'd think this works well with folks who are out of the closet, who would be more likely to be known to the researchers.
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.
The work has not been published in a scientific journal, but it provides a provocative warning note about privacy.I predict these guys are not really doing what they say they are doing. I can't check this prediction, but based on my knowledge outside the MIT world, I'm sure it is quite accurate for undergrads.

Well, I'm very interested in this. For a long time, I've bet money on the horses, but it's only recently that I've started to bet on whether a person was gay. With this new technique, I've been successful 5 times out of 10 (and as anyone playing this field can tell you, that's pretty good!) I hope they refine their model, because sometimes I can't tell whether someone is out of the closet until the horse is out and the barn door has been shut.
