What your email inbox reveals about your personality

• If you don't respond to emails, your coworkers may perceive you as lazy or disinterested, argues Frost & Sullivan CEO Richard Moran.
• Psychologists say the way you clean (or don't clean) your inbox actually does say something about your personality. 
• Those who delete quickly and efficiently might be control freaks, while those with 1,000 unread emails may not be as unorganized as you'd think.

When I texted a friend to say I was thinking about writing an article on what your inbox might reveal about your personality, he immediately texted me back:

"I've got three emails in my inbox. What does that say about me?"

"It means you're the worst," I texted back.

By "you're the worst," of course, I meant, "your ability to manage your digital life is everything I aspire to, and I am therefore insanely jealous."

Managing your inbox is an underrated workplace virtue, argues Richard Moran, CEO of consultancy Frost & Sullivan. When employees don't respond, coworkers perceive them as unorganized and lazy.

At that moment, my personal inbox contained 57 unread emails — but if I'm being completely honest, I'd recently spent a weekend whittling it down from close to 1,000.

As Moran suggests, is my inability to keep a tidy inbox something I should worry about? In other words, if it signaled that I suffered from some deep-seated emotional issue or cognitive deficit beyond simple disorganization. Likewise, I wanted to know if inbox heroes like my friend were actually destined to be more successful than the rest of us.

Of course, it's impossible to look at anyone's inbox and say for sure that he or she is a productivity ninja or a psychopath. Your email management strategy depends heavily on your profession, for example, and the standard flow of email in your office.

But my conversations with experts on psychology and technology still yielded some important (and surprising) insights into the connection between email habits and personality traits. Here's what I found.

The filer/deleter sees a message in his inbox and takes action immediately.

This person reads the email, sends a response if it calls for one, and then either deletes it (because it's no longer useful) or archives it in a specific folder. His email count typically hovers around zero.

Larry Rosen, Ph.D., research psychologist and author of "iDisorder: Understanding Our Obsession With Technology and Overcoming its Hold on Us," admits he falls into this category. Being away from his inbox for too long, he tells Business Insider, makes him nervous — and he suspects it has something to do with his brain.

The brain of a filer/deleter is uniquely wired to react negatively when faced with a bunch of unread messages. "A huge, exploding inbox releases stress-based neurotransmitters, like cortisol, which make them anxious," Rosen says. Keeping a tidy inbox quells that anxiety, at least temporarily.

Ultimately, Rosen suggests, your email-management strategy comes down to your desire for control. Whereas some people are fine leaving their house, their workspace, or their inbox a mess, filers/deleters would go crazy. "They need an external way to have control over the world," Rosen says, and sticking to an inbox-management system fulfills their constant need for order.

The saver has few unread emails, but rarely deletes a message after reading.

According to Pamela Rutledge, Ph.D., director of the Media Psychology Research Center, there are a few potential explanations for this kind of saving behavior. One is perfectionism: "Perfectionists save read emails with the idea that they will get to them [eventually]," Rutledge tells Business Insider. "These same people will have a to-do list that is so long it can't possibly be useful" and a bunch of clothes that need to be mended sitting in the back of the closet.

Essentially, saving emails is a way of deluding themselves into thinking they'll get around to addressing them all.

Rutledge also posits that deleting emails feels too risky for savers. "Some people save read emails for the sense of security it gives to believe they could find stuff if they needed to," she says. "Some of us have more tolerance for uncertainty than others."

The ignorer does not read or delete emails. 

I must confess I was heartened to learn more about the mindset of the email ignorer. According to Ron Friedman, Ph.D., author of "The Best Place to Work: The Art and Science of Creating an Extraordinary Workplace," keeping hundreds or thousands of unread emails in your inbox isn't necessarily a problematic behavior. Although Friedman cautions against "drawing broad conclusions into people's personality and psychological state from their email habits," he offers a few possible explanations for this tendency.

On the one hand, he tells Business Insider, leaving emails unread can signify that you're overwhelmed or disengaged. On the other hand, "it can also mean that you recognize that [monitoring and organizing those emails] isn't helping you achieve progress. And that's a sign of intelligence."

Some email ignorers might actually be more organized and productive than everyone else. After all, Friedman says, "email reflects other people's priorities for you, not necessarily important work that requires your immediate attention."
