It’s a strange sight, a group of people taking a photo of themselves. Dan Ariely, behavioral economist, shines some light on the selfie phenomenon:
The selfies phenomenon is complex, but here are some highlights: Its starting point is those moments we want to capture, for our own memories or to share with others. Now, if we were to stop what we’re doing and ask a stranger to take our picture, we would be stepping out of the moment emotionally: We’d have to stand still while smiling artificially, wait for the picture to be snapped, then try to get back to whatever were doing and feeling.
Selfies solve this problem because we don’t step out of the moment. A selfie can even enhance the moment by getting us to stand closer to one another and look at ourselves together on-screen—a sort of celebration of the shared experience.
Another interesting thing about selfies: We always expect them to produce an awkward, low-quality picture. So those of us who always worry about how we look on camera don’t need to fret as much: Everyone looks bad.
Finally, there is an important interplay between language and decision making at work here: Once we gave a name to the activity of huddling together, looking up at a phone from an uncomfortable angle and taking a picture, it became socially acceptable.
