Have you ever been bored and caught yourself checking Instagram just seconds after you closed it?

I’m sure you didn’t reopen it because you had an overwhelming urge to see more pics of your college roommate's lunch. You did it without thinking, like it was second nature.

If that sounds familiar, then I hate to break it to you: You have a habit.

And what’s more, that habit was built intentionally – by the people who designed your app.

Here’s a simple fact about human nature: The better something makes someone look, the more likely they are to share it.

You probably noticed this on your Instagram feed at the end of last year, when a metric ton of your friends shared their Spotify Wrapped playlist.

What makes sharing the Spotify Wrapped playlist so irresistible?
