The researchers made the subjects take a MyPersonality survey to create a baseline, then asked friends and relatives to judge them with a similar survey. The results were surprising -- the computer model could judge someone better than a friend or roommate by analyzing just 70 likes, and do better than a parent or sibling with 150 likes. The average number of likes per user in the study was 227, enough for the computer to evaluate someone better than almost anyone, with one exception: their spouses.
So what does that mean? We had our senior editor and resident Facebook ace, Nicole Lee give it a whirl, since she was the only one of us who had liked enough things -- it won't work if you're not very active. Bottom line, she was meh on the results (above): it guessed her age incorrectly at 25, thought her more likely single than not (wrong) and gave her a 58 percent openness score, which she called "so off the mark I can't even." It also judged her to be 2 percent lesbian for reasons she can't fathom, though she now plans to include that stat in her profile. On the plus side, Lee did feel the 38 percent neurotic score was "spot on." If you're a reasonably prolific Facebook user, feel free to give it a spin yourself.
