Working Smarter

IT JUST MAY BE the crime of the century. Our minds, thoughts and chief productivity tool--attention--are being stolen by a thief operating with absolute impunity: incessant, unbounded interruptions. An ever-growing volume of intruders--e-mail, texts, apps, phone calls, social media alerts--combined with assaults from increasingly time-panicked humans, are leaving few places safe for chirp-, chime- or ding-free concentration.

Information overload, which includes the recovery time from unnecessary interruptions, cost the U.S. economy $997 billion in 2010, according to Overload!: How Too Much Information is Hazardous to your Organization by Jonathan B. Spira. An Intel study found that lost productivity from information overload alone would cost $1 billion per year for a company its size.

Chronic intrusions shrink attention spans, drive stress by burning up mental and emotional resources and trigger mistakes. An interruption averaging 2.8 seconds--say, one of those blinking notifications in the corner of your computer screen--can double the risk of error, a study by researchers at Michigan State University and the U.S. Naval Research Laboratory found. Increase the duration of the interruption to 4.4 seconds, and you triple the chance of a mistake.

Interruptions play havoc with working memory, fuel overwhelm, and undermine intellect. A study that measured the effects of forced interruptions on resident surgeons performing a simulated laparoscopic cholecystectomy (gallbladder removal) found that surgical mistakes occurred 44 percent of the time with the distractions, and only about 6 percent without. Interruptive questions triggered the most errors, followed by sidebar conversations.

There's a reason airline pilots have mandatory no-interruption zones just before takeoff and landing: Federal regulations prohibit any activity--from nonessential conversations with crew or others in the cockpit to reading nonessential publications--that could distract a pilot during critical phases of the flight.

So, what are the main sources of intrusion, how do they affect us, and what can be done to curb them?

DIGITAL DISTURBANCES

The average businessperson receives and sends about 109 e-mails per day, and that rate is growing each year by 7 percent, according to studies by technology market research firm The Radicati Group. Instant messages are increasing 11 percent, and texting, once confined to the nonwork realm, is bombarding offices, with 67 percent of professionals saying they text for business, according to messaging service HeyWire Business. How interruptive is this? Mobile Marketing Association reports that 90 percent of all texts are read within three minutes.

"It's a huge problem," says Dr. Edward Hallowell, a Massachusetts psychiatrist and co-author of Driven to Distraction, which chronicles the siege on attention. "It's the newest addiction. There are in-patient centers now for people with technology addiction. Marriages break up."

"There's a thrill to it," adds Winifred Gallagher, author of Rapt: Attention and the Focused Life. "Your texts and e-mails are like video games. There's a stimulus and rewards."

The surge of texts and social media notifications in recent years may be leading to a tipping point of terminal distraction and always-on availability. Michael Salem, co-founder and CEO of Vorex, a Plano, Texas-based provider of cloud-based professional services automation software, says he gets 1,000 messages per day. "I'm overwhelmed," he admits. "Responding is a daily thing, 24 hours a day." For a while, he says, he barely slept, taking calls from global users of his product from his bed. His health started to suffer; he gained weight and became anxious from the never-ending assault.

"I counted recently," says Matthew Bellows, CEO of Boston-based Yesware, an e-mail productivity service for salespeople. "I have 22 inboxes, from e-mail to LinkedIn. The idea that I'm supposed to monitor and troll through these is absurd. I get hundreds of e-mails a day. Interruptions and distractions are the biggest drain on productivity for the modern office worker."

THE BATTLE IN THE BRAIN

The volume of intrusions today is unsustainable by any metric: productivity, engagement, physiology or common sense. So what can we do about it? The first step is to understand the impact of constant interruptions on our brain neurons.

Out of all the things your brain could focus on right now, your attention at this moment is on this sentence. This is because you are implementing what's known as top-down attention, in which you choose what to take note of. You set the terms of engagement, giving you control and concentration--that is, if you can block out the distractions of the other kind of attention: bottom-up, which is dictated by something or someone else. Bottom-up attention is part of our survival equipment. When you hear a siren or a car backfire, your attention instantly shifts to the potential threat. The cavalcade of electronic noisemakers--e-mails, texts, IMs, phone calls, notifications--are all bottom-up intruders. They arouse defenses and hijack concentration.

It's a battle that's daunting but winnable. "You are the boss of what's in your head," Gallagher points out. "Attention is a tool, and you can take charge of it. It's a matter of knowing when you want to use your top-down attention, and then you have to suppress the bottom-up stimuli. Otherwise, you become a victim of stimuli."

Interruptions trigger detours that tax working memory and increase the time it takes to accomplish tasks, all of which drives stress. When an intrusion occurs, "it sets off a chain of random events, with people switching activities," explains Gloria Mark, professor of informatics at the University of California, Irvine, and co-author of a study on the subject. On average, she says, "you work on two intervening tasks before you get back to the original task." For example, you might be at work on a marketing project one minute, then shift to an e-mail from a customer, then off on a trip to LinkedIn.

Mark followed 35 managers, engineers and project leaders for three days. She found that the average time people spent on a single task before being interrupted or switching to something else was a whopping three minutes. The amount of time they worked on a device before switching was two minutes, 11 seconds.

The interruption blitz is held in place by fallacies that the human brain is an inexhaustible well that can be crammed with an unlimited amount of information, perform multiple functions simultaneously and switch tasks without decrease in output. The shocking truth is that our gray matter has limits, from working memory to data volume to neural channels that permit us to perform only one high-cognitive task at a time.

Interruptions undermine effortful control, which reflects the ability to regulate impulse control. The more interruptions one has, the more they erode the self-regulation equipment. Feel like you have to check your e-mail even though you just checked it five minutes ago? That's your impulse control and attention span on the blink. Interruptions shred the ability to self-regulate everything from checking e-mail to consuming Häagen-Dazs or Jack Daniel's.

ATTENTION DEFICIT

This is why technology is so addictive. It can destroy the ability to control impulsivity, which means more frequent message checking and web browsing and shorter attention spans. That, in turn, leads to more distractibility and less ability to see tasks through to completion--exactly the sort of symptoms psychiatrist Hallowell began to see in the '90s in patients who thought they had attention-deficit disorder.

But people with true ADD are born with the condition. So Hallowell's patients' fractured attention was a byproduct of something else--an affliction that mimics ADD, set off by interruption and information overload "filling our heads with a cacophony of mental noise" until the brain "loses its ability to attend fully and thoughtfully to anything," Hallowell notes in Driven to Distraction. He dubbed the condition "attention deficit trait."

Once high-producers, people with this condition flit from one thing to the next and find themselves falling behind in their work, which in turn increases time panic and anxiety as they try to catch up. Thus the constant disruptions feed a fear of being overwhelmed and not being able to cope, a signal to the ancient brain to set off the stress response.

"I can feel my heart racing," says Karen Swim, who launched her Sterling Heights, Mich.-based public relations firm, Words For Hire, 10 years ago. She used to be able to manage the electronic flood, but she says the increase in texting over the last couple of years has pushed her coping resources over the edge. "There are days when I feel I have to stop and breathe. It feels like you're on a treadmill that keeps speeding up, and you can't keep up."

THE NO-INTERRUPTION ZONE

Everyone knows the volume of intrusions is counterproductive, but attempting to moderate the flow strikes fear in the hearts of business owners and managers. It shouldn't.

More entrepreneurs would crack down on interruptions if they knew how much it was costing them, says Dan Adams, CEO of Woburn, Mass.-based New England Network Solutions, which provides computer services to small and midsize companies. "Business owners don't know how much time is being lost to these distractions," says Adams, who installs firewalls to track and monitor internet and social media use.

As relentless as the siege is, entrepreneurs and employees don't have to throw up their hands. There is a range of tools available to control the onslaught, improve productivity, and along the way build in stress management controls.

Strategies range from curbing e-mails to limiting personal pop-ins from colleagues. U.S. Cellular, Intel and professional-services giant Deloitte are among large firms that have attempted no-e-mail days--not mandating a complete shutdown of electronic messages, but encouraging in-person or voice communication, especially among co-workers--which may cut down on unnecessary distractions.

"Without uninterrupted time you can't listen to someone, write good code or think," says Yesware's Bellows, who once spent a year at a Buddhist retreat meditating for hours a day. "Those tasks take concentration and focus that is quickly taken away by devices."

INTERRUPTIONS

Bellows is trying to stem the tide of interruptions. Instead of interrupting one another with questions, Yesware employees send messages via a HipChat.com intranet page that colleagues can review on their own time, when they have a break in the action. Bellows blocks out uninterrupted time on his calendar to think, urges everyone to close laptops and not check messages during meetings and reads and responds to his e-mail in designated chunks a few times a day.

The latter strategy in particular can dramatically reduce interruptions. If your e-mail automatically checks and feeds you messages every five minutes, that's a potential of 96 interruptions over an eight-hour day. However, if you manually check it every 45 minutes, that cuts the total to 11. Researchers at Oklahoma State University say the most productive checking schedule is four times per day. UC Irvine's Mark recommends that you plow through as much e-mail as you can in three scheduled periods per day; the rest of the time, it should be turned off.

Other interventions aim to block off no-interruption zones. Leslie A. Perlow, Konosuke Matsushita professor of leadership at Harvard Business School, developed the "quiet time" program, which walls off all intrusions during certain times of the day.

She deployed the method at a software company whose engineers were having trouble creating products without working nights and weekends. After a period of investigation, Perlow discovered that the engineers were being interrupted so often they didn't have time to think and couldn't get enough done during regular hours. With everyone falling behind schedule, a crisis mentality developed, in which people felt entitled to interrupt anyone at any time.

Perlow's solution was to set aside a certain portion of the day, before 11 a.m. and after 3 p.m., for uninterrupted work. (Normal interruptions could take place during that four-hour window.) The results: 59 percent of engineers reported that their productivity increased in the morning interruption-free zone, and 65 percent said the same for the afternoon. With heads cleared, 41 percent even reported that their productivity jumped during the interruption portion of the day.

Harman Singh likes the idea of quiet time. The founder and CEO of WizIQ--who gets upward of 200 messages each day--says he's been thinking about the need for rules to control the flood at his online education company. "It's gotten crazy," he says. "I don't get enough time to think. It's a menace."

His most frustrating distraction: mobile messaging via WhatsApp. He has considered getting off the app but is concerned about how investors who contact him that way might react. As with most thoughts of managing interruptions, there is fear. Would they respect boundaries? But Singh believes that ultimately his investors would rather have him engaged in productive thought and running his company than buried in social media and needless communication.

With the growing advances in brain research, we’re getting a much better picture, literally, of when our command center works and when it doesn’t. Researchers say MRI scans of fatigued brains show so little activity, they look like they are sound asleep.

I’m sure you know that feeling around 4 p.m., when it seems like you’re swimming in molasses, and you have to expend twice the effort to get something accomplished that you need when you are fresh. The reality is that there is a limited period that the brain can stay focused without wandering or going into brownout mode. Researchers say 90-minutes to three hours of time and task, and the brain has to step back from task to reset.

The instinct to never pause and go to the mental wall may be admirable, but it’s not productive—and it’s one of the best ways to kill employee engagement. Studies show that engagement is not so much an attitude as a state of motivated attentiveness.

FULL ABSORPTION

One of the key hallmarks of engagement is absorption, full concentration in the moment. Pushing gray matter to the edge insures there won’t be much of that. Fried, overloaded brains are characterized by tension, inability to focus, slower processing, and an inability to handle complex tasks.

Even if dedication and commitment are there, engaged employees can’t deliver extra effort when mental resources are spent. Fatigue and exhaustion also undercut another key metric of engagement, the physical, energetic resources of vigor.

There is a fallacy in the knowledge economy that, because we are just sitting on our behinds, that the brain is a kind of unlimited well. We’re not being physically taxed, so the mind can just keep going. Brain scientists I’ve spoken with have told me that the brain goes down well before the body. That means, so does the chief productivity tool, attention, and the prospects for engagement.

FRACTURING FOCUS

Any organization that wants engaged employees has to have attentive employees, yet everything about the nature of work today undermines that—unbounded interruptions, information overload, social media intrusions. It’s not how much volume we can cram into our heads, but how we manage demands that leads to the focus necessary for engaged performance. Yet few organizations have tied shrinking attention to engagementm si more and more intrusions pour in.

It’s often thought that engagement can be measured by the amount of commitment to the organization, but that’s not enough to drive engagement, which is a function of the specific effort an employee brings to the task. As Alan Saks at the Rotman School of Management at the University of Toronto put it in one study, “Engagement has to do with how individuals employ themselves in the performance of their job,” not attachment to the organization.

It’s great when people are dedicated to the cause, but, if they have the attention span of a gnat, there won’t be much in the way of engagement. Disengagement is more like it, and, in fact, that is the trend these days as attention spans shrink, thanks to nonstop interruptions and information overload.

Leaders need to be alert for the signs of disengagement—withdrawal, absenteeism, personal conflicts, falling behind schedule, burnout—when attention vanishes in the face of excessive demands without compensating latitude or choice. Researchers say that burnout is a marker for the opposite of engagement’s dedication, absorption and vigor. Instead, there is estrangement from the goals of the organization and a downward spiral of physical, mental, and emotional exhaustion, cynicism, and futility.

THE OPPOSITE OF BURNOUT: ENGAGEMENT

That leads to the logic that less burnout can promote more attentive employees who have the potential to be engaged. What areas do organizations have to adjust to reduce the burnout track and promote more focus? Saks points to research from burnout scholar Christina Maslach and associates. “Job engagement is associated with a sustainable workload, feelings of choice and control, appropriate recognition and reward, a supportive work community, fairness and justice, and meaningful and valued work.”

People who have a sustainable workload are naturally going to be able to bring more focus to the task than if they have depleted their coping resources. Choice and control keep stress away, which prevents the brain from having focus constricted to the narrow fixation of a perceived false crisis. Recognition and supportive work means that attention is appreciated and nurtured, while fairness and meaningful work internalize the importance of doing quality, attentive work.

So much of the way we work today is simply autopilot, reflexively responding to the demands without managing them. The research shows that engagement, and productivity, are not the result of brain drain, of cognitive feats of endurance, but the opposite, promoting behaviors and policies that allow minds to find the space to focus.

That’s hard to engineer when most people are in a state of triage all day. Yet there are other choices than triage, other approaches to the way we do our work that are actually based on the evidence of what has been proven to be productive. From no-interruption zones to email management to the power of full-absorption goals, there are a wealth of tools that can bring about the gains in commitment, attention, and motivation that prime the pump for engagement.

This is where development programs can make a big difference, providing a path out of reflex mode to practices that are the most engaging and productive. If you are interested in increasing the attention, engagement, and productivity of your employees, click on the button below for more details.

There are a lot of reasons why email has overwhelmed capacity to deal with it, but the main one is that it’s easy. It’s easy to click the send button, easy to not get up from your seat, easy to avoid speaking with someone in person about an issue. But that convenience is an illusion, because we don’t see the cumulative blowback. As we discussed in the Working Smarter blog last week, every email results in six emails—three going, three coming back, so we need a few more gallons of caffeine every day to triage through the mess. 

Cutting email tonnage, not only opens up more time to get our work done, it also reduces the damage to the chief productivity tool: attention. Managing email is really about managing the interruptions that fracture attention, as we’re forced to shift from primary task to secondary items, most of the time unrelated to what we’re doing.

The inability to keep attention on a task for longer than a nanosecond, not surprisingly, affects the quality of our work. Distracted minds don’t see the big picture, make decisions too quickly, send curt messages, can’t focus enough to produce innovative solutions, and have little semblance of work-life balance.

Growing stacks of unread email also fuel overwhelm and a belief that things are out of control. That drives a perception you can’t cope with the avalanche, which sets off the stress response. Taking back control over email shuts down the feeling of chaos and with it, stress that drives poor decisions and health problems. So controlling email is a key stress management strategy.

SET THE TERMS OF ENGAGEMENT

We can get control back by choosing when we interact with email—by setting the terms of engagement with our devices, by checking email manually and turning off all the dingers and noisemakers. That means creating some boundaries—rules in a world where there are none. The way forward is determining limits/norms for information management in every team, department, and organization.

Unlike the telephone, which was adopted over a long enough period that we were able to develop rules for how to use it, e-tools arrived so suddenly and overwhelmingly that they were running the show before anyone knew how to use them effectively. But the good news is that, since there are no rules, they’re up for grabs. That means we can set some.

It’s amazing what can happen with a little law and order. Harvard’s Leslie Perlow did an experiment with a software company whose employees were working nights and weekends to get products completed on time. She instituted a program there called Quiet Time. For four hours a day, two in the morning, two in the late afternoon, there was to be no messaging, so people could concentrate and get their work done. The rest of the day people could revert to messaging as usual. The program resulted in productivity increases of 59% and 65% in the two message-free zones, and jumped 43% even in the period with normal interruptions, because minds were more focused and less harried. The company was able to complete a new product in record time without staff needing to work nights and weekends.

THE SECOND LAW OF EMAIL REDUCTION

Last week's blog introduced the first Law of Email Reduction ("Spay and Neuter to Cut Volume"): Do more in-person messaging. Our second email law is:

Rules for etool use control the abuse of email.

It holds that rules for e-tool use rein in the chaos and reduce the amount of time blown on messaging. It’s not hard to come up with ideas for email rules. We all know the stuff that drives us crazy about email. When I asked what rules they would like to see placed on email usage, managers at a large aviation firm licked their chops and gave me this list, which you may want to take some notes on:

• Deactivate the ‘reply-all’ function

• Develop a weekend code of ethics restricting email to emergencies

• Disable the ghost email alert notification

• Never expect an immediate response from an email

• Pick up the phone and call

• No emails between 8 p.m. and 6 a.m.

• Only send email if there’s an action required

• Don’t send one-line “thank you” and “got it” messages

THE MOST IMPORTANT RULE OF EMAIL MANAGEMENT

No doubt, there are more than a few rules on that list you’d like for your own e-tool handbook. Here’s one of the most important rules that should be a part of any email etiquette book:

Keep email software turned off and check messages manually at set schedules.

There’s no reason to have computers and devices chiming like deranged glockenspiels all day, or blinking those annoying notifications in the corner of your monitor. Turning off message software will shut down the sound and light circus and keep intrusiveness to a minimum. You choose when you’re going to be interrupted, rather than leaving it to anyone with a random thought.

Some 68% of folks keep Outlook or Entourage on autocheck all day, checking continuously. One study (Jackson, 2003) found, that if you keep your system on autocheck every five minutes, you have a potential of 96 interruptions in the course of the day! You can slash that down to 11, if you check mail manually every 45 minutes.

That’s still a lot of checking. You can put a fence around email by restricting yourself to a few retrieval and sending times each day. Manual checking at specific schedules offers the least interruptions and maximum productivity. Try using what researchers have identified as the most optimum email schedules. Holding email to two checks a day results in significantly fewer hours worked daily compared to processing email continuously (Trafton, 2003, Jackson 2003). The most productive schedule is twice or four times a day, according to researchers at Oklahoma State.

When we control the checking, we stop the anarchy. There are a number of other rules that can be easily implemented in any team, department, or organization.

If you would like more rules to help manage email and are interested in an information management workshop at your organization, click the button below for more details. And send me your thoughts on email rules you would like to see.

There is light at the end of the email in-box.

The confessions began to tumble out. One woman at a work-life balance workshop I was leading in New York raised her hand and said sheepishly, “I take my smartphone to bed.” 

“So do I,” chimed in another consultant quickly. “I’ve been sleeping with my phone for years,” offered a third woman.

This is what I call unrequited love. You give your devices undivided love and attention, and what do you get for it? The attention span of a gnat. Constant interruptions. And chronic stress that suppresses your immune system and takes your body down.

No matter what line of work you’re in these days, chances are good there’s only one business you’re really in—the clicking business—checking, sending and receiving piles of email from anyone with a random thought in their heads. How many hours of your day are sucked up by out-of-control messaging?

SPAY AND NEUTER YOUR EMAIL

It’s worth doing the calculating, because your best years are disappearing down the black hole of unbounded email. The average corporate user burns up three-plus hours a day on email, 133 emails and 77 Instant Messages. That adds up to a total of 100 DAYS a year doing nothing but email. That spills over into the nights and early mornings, making any semblance of work-life balance a mirage.

And then there’s the financial cost of email overload—all that lost productivity. Intel estimates that for a company with 50,000 knowledge workers the tab is $1 billion in lost productivity from email overload. Intel, along with Google, Microsoft and Xerox, formed the Information Overload Research Group to fight what they call “email pollution,” a good term for this blight blocking out work and life and cranking up stress.

The approach to email overload so far has been to just react to all the incoming. Get up earlier, stay later. But that’s not viable in a 24/7 world where the avalanche keeps on coming. As any engineer could tell you, we have structural limits.

To cut down on the deluge, you have to make changes that will actually reduce the volume of email. Email is the electronic rabbit, multiplying like oversexed cottontails. Every email has offspring, and they have offspring. A single message creates six messages—three going, three coming back, say researchers. Even at the standard rate of three minutes an email, that’s 18 minutes down the tubes for every email you send. Add it up. We have to spay and neuter our email.

I talked to a VP at a major technology firm in San Diego who gets more than 250 emails a day. He starts at 5 in the morning with two hours of email at home before going to work, then spends several hours more on message duty after he gets into his office. “It just seems like I can never catch up,” he told me, looking completely drained.

The sooner we can see email for the rabbit it is, the quicker we can keep the population down. Email plays on the social animal’s need for positive reinforcement, even if it’s just a canned reply-all mail or spam on the other end of the line. We have to understand how we are being played by this dynamic and use but not abuse the technology.

THE MORE YOU CHECK EMAIL, THE MORE YOU HAVE TO CHECK IT

In a study on email addiction, Rutgers University researcher Gayle Porter found that technology can be just as addicting as chemical or substance abuse. Have you ever had that feeling that you have to check email though you just checked it five minutes ago? That’s your impulse control out of control, thanks to the interruptions, which erode a part of your executive attention function that regulates impulsivity. The more you check email, the more you have to check it.

With friends like yourself around, who needs enemies?

To actually cut the volume of email, we have to start reducing the tonnage. There are three ways to do that. We’ll cover the first law of email reduction in this blog.

Email Law # 1: Do More In-Person Messages

More phone and face-to-face contact seems like heresy, but the evidence at companies such as Deloitte & Touche and U. S. Cellular, which are mandating less email and more phone and face-to-face messaging, shows that reduced email increases productivity and builds rapport and relationships. Even former email addicts have come around to become true believers and are increasing their productivity through in-person messaging with co-workers.

Email is a handy tool to set up a phone conversation, in which you can handle all the issues in one go, instead of going back and forth in the usual volley of trying to extract the piece of information you need from someone who keeps sending fragments of the answer you’re looking for. You fire off an email to coordinate a time to speak on the phone or meet live. You can mention, if you like, that you’re on an email reduction drive and that this is a way to save both of you multiple emails.

This method combines the best of both worlds, using email for a specific and limited reason, and the phone to nail down all the back and forths that would normally be perpetuated by the email cottontails. You are respecting your colleagues’ time this way, and they will appreciate it.

RISING TO THE IMPORTANCE OF A PHONE MESSAGE

Email has overwhelmed our lives because it’s convenient. We don’t have to physically interrupt someone with a call or pop-in. In the old days, the message had to rise to the importance of a phone call before it entered the universe. It helped to limit messages to the most important ones. There are zero inhibitions to clicking email.

A manager at an aerospace company told me at a work-life workshop I conducted that he’s gotten his email-checking down to twice a day, while colleagues are indulging 20 times that often. He makes it clear that his preferred mode of communication is the phone and that an email needs to be worth sending before clicking. When he volunteered his solution before a group of fellow managers, their jaws hit the floor. He looked calm, unbeleaguered, in control of his destiny. He’d reined in the abuse with boundaries that worked.

If most of your mail is coming from outside your office, add “No Reply Necessary” to the subject line or body of the message to let the other person know they don’t have to get back to you. If the bulk of mail is coming from your team or department, use the 100-Foot Rule. Get up from your desk and deliver the message in person to anyone within 100 feet of your desk, and then expand it to 200 or 500 feet for a little extra exercise.

For every email you don’t send, you save 18 minutes (at the standard rate of three minutes an email). How many messages can you resist sending today and much time can you save?

It's the gospel of productivity in a maxed-out world: Multitasking helps you get more done faster. The only thing is, it doesn't, says David Meyer, a cognitive scientist at the University of Michigan, where he serves as director of the Brain, Cognition and Action Laboratory.

"When you perform multiple tasks that each require some of the same channels of processing, conflicts will arise between the tasks, and you're going to have to pick and choose which task you're going to focus on and devote a channel of processing to it," explains Meyer, one of the country's leading experts on multitasking.

Meyer has been at the forefront of research for several decades on how the brain processes information and copes with multitasking. He has investigated the brain's speed, accuracy and memory in information processing while working with psychologist David Kieras for the Office of Naval Research. A study Meyer co-wrote on the limitations of multitasking ("Executive Control of Cognitive Processes in Task Switching") went viral in 2001, setting off the first awareness of the counterproductivity of simultaneous tasks.

Meyer's work has documented that humans have distinct bandwidth challenges, which makes multitasking problematic. It turns out the brain's ability to process information is limited in a variety of ways—from processing channels to limits on data volume, velocity and working memory—that stymie true, simultaneous activity. Multitasking multiplies only frustration.

MENTAL BROWNOUTS

Counter to conventional wisdom, you can't do two high-cognitive tasks at once, Meyer says. When you're on the phone and writing an e-mail at the same time, you're not doing them at the same time. You're actually switching back and forth between them, since there's only one neural channel through which language flows. In that switching there's a cost: stress, as your brain neurons try to get themselves around the new task or where you were on the primary task each time you switch.

"If you have a complicated task, it requires all your attention, and if you're trying to spread your attention over multiple tasks, it's not going to work," he says.

That's heresy in a time-urgent world with the attention span of a macaque on crack. Meyer admits that multitasking is not only getting more prevalent, but it's also "very often highly inefficient and can be dangerous to your health."

Multitasking kicks thoughts down from the top floors to rote mode, where you don't have full attention on what you're doing, triggering mistakes and surface understanding. You wind up on autopilot in a retaliatory pattern of acting before you think. 

Even the most adept multitasker will "crash and burn" trying to resolve simultaneous conflicting demands, Meyer says. That means you could wind up sending the wrong e-mail; blow an account; have a brownout in which too much access to the cerebral grid shuts down critical thinking; or worse, find yourself in a truly hazardous situation, such as driving while using a cell phone.

"When you're driving, you have to use the language channel to talk, read signs, plan your next move. If you're trying to have a cell phone conversation while you're doing that, either the phone conversation will suffer or the driving," Meyer says. He points to the growing number of auto accidents caused by people sending texts from behind the wheel.

SIMULTANEOUS INATTENTION

The conflicts triggered by incessant multitasking can set off chronic stress and slow you down, shredding productivity. In fact, trying to complete two or more tasks at once can take 40 percent more time or longer, depending on the complexity of the task, Meyer says.

Performance isn't the only thing that suffers when brains are overwhelmed by multiple tasking. Creativity and innovation don't come from people who are multitasking. "You ought to be setting aside large chunks of time where you just think," Meyer says. "Einstein was not multitasking when he was dreaming up the special and general theories of relativity."

The good news is that there is hope for the attention-span-challenged, in the form of self-regulation through better time management and scheduling. "If you're disciplined enough, you can map out the usage of your time in a way that minimizes your exposure to interruptions," Meyer explains.

To improve attention and productivity, you have to shift the idea of  multitasking from simultaneous to alternating tasks. You do one task for a while, then another task. Unless you prefer the mistakes, meltdowns, and overwhelm of trying to do what your brain can't.
