Their study does not tease out why socialising on Facebook has a different effect from socialising in person. But an earlier investigation, conducted by social scientists at Humboldt University and Darmstadt’s Technical University, both in Germany, may have found the root cause. These researchers, who presented their findings at a conference in Leipzig in February, surveyed 584 users of Facebook aged mostly in their 20s. They found that the most common emotion aroused by using Facebook is envy. Endlessly comparing themselves with peers who have doctored their photographs, amplified their achievements and plagiarised their bons mots can leave Facebook’s users more than a little green-eyed. Real-life encounters, by contrast, are more WYSIWYG (what you see is what you get).
