Facebook internal study: 'Hard Questions: Is Spending Time on Social Media Bad for Us?' (Spoiler: Yes and No)

The bad: In general, when people spend a lot of time passively consuming information — reading but not interacting with people — they report feeling worse afterward. In one experiment, University of Michigan students randomly assigned to read Facebook for 10 minutes were in a worse mood at the end of the day than students assigned to post or talk to friends on Facebook. A study from UC San Diego and Yale found that people who clicked on about four times as many links as the average person, or who liked twice as many posts, reported worse mental health than average in a survey. Though the causes aren’t clear, researchers hypothesize that reading about others online might lead to negative social comparison — and perhaps even more so than offline, since people’s posts are often more curated and flattering. Another theory is that the internet takes people away from social engagement in person.

The good: On the other hand, actively interacting with people — especially sharing messages, posts and comments with close friends and reminiscing about past interactions — is linked to improvements in well-being. This ability to connect with relatives, classmates, and colleagues is what drew many of us to Facebook in the first place, and it’s no surprise that staying in touch with these friends and loved ones brings us joy and strengthens our sense of community.
