Researchers say they’ve developed an algorithm that uses posts on the social media giant Instagram to identify depression more effectively than doctors can.
According to the study, the algorithm could accurately identify depression in 70% of their study’s participants. Doctors, on the contrary, are successful only 42% of the time. The study looked at 44,000 Instagram photos posted by 166 people, 71 of which were diagnosed with depression.
The algorithm discovered that depressed people,were more likely to post photos with the black and white Inkwell filter, or no filter at all. People who aren’t depressed, on the other hand, preferred the Valencia filter, which brightens the image.
Those who had depression typically had fewer faces in their posts and received fewer “likes”.
