Does Facebook know you better than your friends do, or even better than you know yourself? Lily Ames conducted an experiment to find out and reported the results to CBC Radio’s technology program Spark.
The personality program she tried is called Apply Magic Sauce, developed by The University of Cambridge Psychometrics Centre. It takes your Facebook “likes” and gives you a score based on a database of six million social media profiles.
When Lily ran her Facebook likes through the program, she was surprised at how well it scored on most of 20 things. It nailed her age within two years, religion, gender, education in journalism.
Then she compared those results with a standard test from Cambridge. It categorized her personality in five areas: openness, conscientiousness, extraversion, agreeableness, and neuroticism. She agreed with the test results with the exception of extraversion which she thought was low, especially when she considered extraversion as one of her defining traits.
Then five of Lily’s friends filled out a questionnaire on her personality. Surprisingly, the Facebook likes corresponded more closely to the standard test than either her own opinion or those generated by her friends.
Not so surprising says David Stillwell, a researcher at the Psychometrics Centre. Who we are is a philosophical question. Then, maybe we are not just one but different personalities; our self-impressions, the digital projection of ourselves online, and our personality as perceived by friends.
I was curious about what my Facebook likes would reveal about me so I tried the Apply Magic Sauce algorithm only to find that I didn’t have enough likes on Facebook to make an assessment. “Sorry, we are unable to generate a prediction.” was the reply “An insufficient number of your Likes match with those in our database, and we don’t believe in guesswork. Please take our full personality test, if you would still like to receive scientific feedback on your traits. Thanks!”
So I did. I took the full personality test and here’s the results. I scored highest on openness,73%, which reflects intellectual curiosity. Next was agreeableness, 69%, which suggests that I’m easy to get along with. Then conscientiousness, 66%, a measure of how organized I am. Extraversion, 54%, a gauge of social interaction. Finally neuroticism, 24%, my response to life’s demands. “Based on your responses, you come across as someone who is rarely bothered by things, and when they do get you down the feeling does not persist for very long,” the assessment elaborated.
It seemed fairly accurate, but then, why wouldn’t it when I’m the one who answered the questions?
Social media such as Facebook contain a wealth of data about ourselves that we may not intentionally reveal. Lily couldn’t even remember liking the Saskatchewan Roughriders. And a she was only being ironic when she “liked” new fashion trend.
No problem, says Stillwell. “From a prediction perspective, it doesn’t matter, as long as there is a link between people liking something and their personality. If everyone likes it because they are being ironic, then maybe it would be related to low agreeableness. But it doesn’t matter because the prediction still works.”
