In today’s digital world, we’re often expected to be on email at all times. Recent studies show that office workers spend almost a third of their total workday reading and responding to messages. This constant connectivity can be harmful: scientists have established a clear link between spending time on email and feeling stress.
It seems irrational. Why do we spend so much time doing something that has such a negative impact on our well-being? The fact of the matter is that even though we may not care for the content of every email we receive, many of us are addicted to the act of checking email. It activates a primal impulse in our brains to seek out what behavioral psychologists call “random rewards.”
Imagine that your email is like a slot machine. Most of the time when you “pull the lever” to check your email messages, you get something disappointing or bothersome—a communication from a frustrated client or a boss with an urgent request. But every once in awhile you pull the lever and you get something exciting—an email from a long-lost friend, a flattering request to speak at a conference, or (if you’re really lucky) a video of goats jumping on things. And it’s those random rewards, mixed in with all the mind-numbing updates and irksome requests that we find so addictive. They make us want to check our email again and again and again, even when we have better things to do.
But striving for inbox zero is, of course, a Sisyphean effort at best. Just when you think the task is complete—ping!—a new message rolls in. And then another. And another. The work will never be done, and yet email still inspires this strange sense of obligation. The more unread messages we have in our inboxes, the more anxious we feel. The more time that passes before we can reply to a message, the more we apologize. How many times have you started an email with, “I’m sorry I couldn’t get back to you sooner but…”? Somewhere deep down we truly feel that we owe everyone a response.
