Researchers have long explored whether using Facebook makes us more full of ourselves. Now a study of Facebook data has found that users actually get less self-obsessed — at least as measured by certain words in their posts — as they get older.

As Mark Liberman writes at Language Log, researchers at the World Well-Being Project at the University of Pennsylvania analyzed the pronouns people used in Facebook posts and broke down the results by age. They found that the use of first-person singular pronouns like “I” and “me” was lower among older users.
