Modern life now forces us to do a multitude of things at once — but can we? Should we?

        Forget invisibility or flight: the superpower we all want is the ability to do several things at once. Unlike other superpowers, however, being able to multitask is now widely regarded as a basic requirement for employ-ability. Some of us sport computers with multiple screens, to allow tweeting while trading pork bellies and frozen orange juice. Others make do with reading a Kindle while poking at a smartphone and glancing at a television in the corner with its two rows of scrolling subtitles. We think nothing of sending an email to a colleague to suggest a quick coffee break, because we can feel confident that the email will be read within minutes.
        All this is simply the way the modern world works. Multitasking is like being able to read or add up, so fundamental that it is taken for granted. Doing one thing at a time is for losers — recall Lyndon Johnson’s often bowdlerized dismissal of Gerald Ford: “He can’t fart and chew gum at the same time.”

        In 1958, a young psychologist named Bernice Eiduson embarked on an long-term research project — so long-term, in fact, that Eiduson died before it was completed. Eiduson studied the working methods of 40 scientists, all men. She interviewed them periodically over two decades and put them through various psychological tests. Some of these scientists found their careers fizzling out, while others went on to great success. Four won Nobel Prizes and two others were widely regarded as serious Nobel contenders. Several more were invited to join the National Academy of Sciences.
     After Eiduson died, some of her colleagues published an analysis of her work. These colleagues, Robert Root-Bernstein, Maurine Bernstein and Helen Garnier, wanted to understand what determined whether a scientist would have a long productive career, a combination of genius and longevity.
    There was no clue in the interviews or the psychological tests. But looking at the early publication record of these scientists — their first 100 published research papers — researchers discovered a pattern: the top scientists were constantly changing the focus of their research. 
    
     These four practices — multitasking, task switching, getting distracted and managing multiple projects — all fit under the label “multitasking”. This is not just because of a simple linguistic confusion. The versatile networked devices we use tend to blur the distinction, serving us as we move from task to task while also offering an unlimited buffet of distractions. But the different kinds of multitasking are linked in other ways too. In particular, the highly productive practice of having multiple projects invites the less-than-productive habit of rapid task switching.

To see why, consider a story that psychologists like to tell about a restaurant near Berlin University in the 1920s. (It is retold in Willpower, a book by Roy Baumeister and John Tierney.) The story has it that when a large group of academics descended upon the restaurant, the waiter stood and calmly nodded as each new item was added to their complicated order. He wrote nothing down, but when he returned with the food his memory had been flawless. The academics left, still talking about the prodigious feat; but when one of them hurried back to retrieve something he’d left behind, the waiter had no recollection of him. How could the waiter have suddenly become so absent-minded? “Very simple,” he said. “When the order has been completed, I forget it.”
      One member of the Berlin school was a young experimental psychologist named Bluma Zeigarnik. Intrigued, she demonstrated that people have a better recollection of uncompleted tasks. This is called the “Zeigarnik effect”: when we leave things unfinished, we can’t quite let go of them mentally. Our subconscious keeps reminding us that the task needs attention.
The Zeigarnik effect may explain the connection between facing multiple responsibilities and indulging in rapid task switching. We flit from task to task to task because we can’t forget about all of the things that we haven’t yet finished. We flit from task to task to task because we’re trying to get the nagging voices in our head to shut up.
     

Six ways to be a master of multitasking

1. Be mindful
“The ideal situation is to be able to multitask when multitasking is appropriate, and focus when focusing is important,” says psychologist Shelley Carson. Tom Chatfield, author of Live This Book, suggests making two lists, one for activities best done with internet access and one for activities best done offline. Connecting and disconnecting from the internet should be deliberate acts.
2. Write it down
The essence of David Allen’s Getting Things Done is to turn every vague guilty thought into a specific action, to write down all of the actions and to review them regularly. The point, says Allen, is to feel relaxed about what you’re doing — and about what you’ve decided not to do right now — confident that nothing will fall through the cracks.
3. Tame your smartphone
The smartphone is a great servant and a harsh master. Disable needless notifications — most people don’t need to know about incoming tweets and emails. Set up a filing system within your email so that when a message arrives that requires a proper keyboard to answer — ie 50 words or more — you can move that email out of your inbox and place it in a folder where it will be waiting for you when you fire up your computer.
4. Focus in short sprints
The “Pomodoro Technique” — named after a kitchen timer — alternates focusing for 25 minutes and breaking for five minutes, across two-hour sessions. Productivity guru Merlin Mann suggests an “email dash”, where you scan email and deal with urgent matters for a few minutes each hour. Such ideas let you focus intensely while also switching between projects several times a day.
5. Procrastinate to win
If you have several interesting projects on the go, you can procrastinate over one by working on another. (It worked for Charles Darwin.) A change is as good as a rest, they say — and as psychologist John Kounios explains, such task switching can also unlock new ideas.
6. Cross-fertilise
“Creative ideas come to people who are interdisciplinary, working across different organisational units or across many projects,” says author and research psychologist Keith Sawyer. (Appropriately, Sawyer is also a jazz pianist, a former management consultant and a sometime game designer for Atari.) Good ideas often come when your mind makes unexpected connections between different fields.
