Picture this scene: It’s 30 minutes into my workday and I’ve already ticked three things off my To Do list. I’ve got something done about finances, finalized a networking meeting, polished a pitch, and am ready to do some serious writing. Then all of a sudden, my internet connection is down. Whoa! How can anyone get anything done without the internet? After some minutes of panic and ranting, I begin to do what I can, offline. And then, eventually, the internet’s absence reveals some beliefs I had wrong about multitasking because—surprise!—work flows smoothly until the end of a most productive day, despite my not being able to check and respond to messages or quickly research points.
While the ability to work on simultaneous tasks has its merits, knowing where we got it wrong about multitasking gives us control over the work process. Here are 10 things we’ve had wrong about multitasking:
1. It’s not really multitasking.
Multitasking is actually switching between tasks. Studies by psychologist René Marois at Vanderbilt University revealed that when humans attempt to do two tasks at once, execution of the first task leads to a delay in the second task because a bottleneck occurs in the brain’s information processing area. Simply put, the brain cannot effectively do two things at once.
2. Not all work can be done with multitasking.
Multitasking can only be done when one task is automatic, such as showering or walking. In The Multitasking Mind, authors Dario Salvucci and Niels Taatgen cite reading while mixing a bowl of ingredients and pulling weeds in the garden while listening to the radio as examples of effortless multitasking. Difficulties come up when tasks involve the same brain processing or body part, such as typing and using a mouse (both require the right hand) or driving and scanning a navigation device (both require vision). The most intense conflict is multitasking in the head, where cognitive and linguistic brain processes create interference, such as reading while having a conversation.
3. Not everyone can multitask.
Some people are better at multitasking than others, but they are not necessarily those who multitask a lot. “In fact, the more likely they are to do it, the more likely they are to be bad at it.” This is what Dr. David Sanbonmatsu and Dr. David Strayer, psychology professors at the University of Utah, found in a research study. The study suggests that people multitask not because they have the ability, but “because they are less able to block out distractions and focus on a singular task.”
4. Multitasking does not save time.
Time-saving is another major thing I got wrong about multitasking. Switching from one task to another or doing two or more tasks in rapid succession uses up seconds. Dr. Joshua Rubinstein, Dr. Jeffrey Evans and Dr. David Meyer conducted experiments in which young adults switched between tasks like solving math problems or classifying geometric objects. They found that multitasking actually takes as much as 40% of productive time.
5. Multitasking is not efficient.
The study of Rubinstein, Evans, and Meyer additionally showed that multitasking involves more errors that occur from cognitive load in the brain. The brain needs to not only adjust to the second task but also to remember where it stopped in the original task. If counting is interrupted by a second task, you need to reorient and remember where you stopped counting in order to proceed with an accurate count. Errors also occur with activities that involve critical thinking.
6. Multitasking can be dangerous.
Air traffic controllers work with heightened stress levels caused by the strenuous effort required to focus on their tasks. They are aware of the dangerous consequences of one mistake. Near-fatal results can also take place in the medical field, as in the case of a 56-year-old male dementia patient. At a visit during hospital rounds, his attending physician instructed the resident to discontinue his anticoagulation medication. The hospital’s computerized provider order entry system (CPOE) allowed for this to be done in real time. The resident began to enter the order into her smartphone but received a text message from a friend about a party, which she responded to. The physician and resident then continued on their rounds. The resident didn’t complete the entry to discontinue the medication resulting in an emergency open-heart surgery, which the patient, fortunately, survived.
7. A multitasking boss sends the wrong signal.
In her book, The Silent Language of Leaders: How Body Language Can Help—or Hurt—How You Lead, Carol Kinsey Goman talks about leaders’ non-verbal messages. An example of this is a boss who verbally tells her team they are important and are always welcome in her office. Yet, when a team member seeks her out, this boss answers questions while writing an email or shuffling papers and does not make eye contact. Result: the team feel they don’t even get half of this leader’s attention.
8. Multitasking gets in the way of meetings.
You’d think with all the devices available, meetings would cover more in less time. Attendees should be able to note down their reporting topics and action items. We got that wrong about multitasking too. What usually happens is people lose track of the discussion because they are tweaking their reports or noting down action items. In a productive meeting, the attendees are also mentally present and actively engaged in the discussion. One assigned person takes down the meeting minutes for distribution later.
9. Multitasking dulls memory and the ability to organize.
What we often believe to be memory problems are actually attention problems. You cannot remember later what you do not pay attention to now. Child and adult psychiatrist, Dr. Edward Hallowell describes attention deficit trait (ADT) as a response to our hyperkinetic environment. When an individual is dealing with more inputs than they possibly can, their brain circuits get overloaded. They are unable to stay organized, set priorities, or manage time.
10. Multitasking detracts from relationships.
We justify work multitasking as a means to have more time for our relationships. Well, we got that wrong about multitasking too. As more mobile apps become available for work, chores, and errands, the role of multitasking with mobile phones has reached villainous status. No doubt you’ve experienced the frustration of having a conversation with a partner or a friend that is interrupted by text messages, emails, or actual phone calls. A study by the University of Essex showed the mere presence of a mobile phone—even when not in use—during personal conversations becomes a barrier to closeness, trust, and empathy.
Why what we got wrong about multitasking is good news.
It’s okay not to multitask. Focusing on one task allows you to finish it sooner and begin the next task. You can also better focus on important face-to-face encounters.
When you need to multitask, you can do it well. Those who do not usually multitask make the best multitaskers, according to the Strayer and Sanbonmatsu study.
You can choose effective task pairings and devices. Have double PC monitors to facilitate research, use foot pedals when transcribing, and listen to select audiobooks while driving.
Oh, and by all means, whistle while you work!
