Want to find out if you're an effective multitasker? Take this quick quiz:
The results are in: you fail! Or, more accurately, multitasking fails. Many of us pride ourselves on juggling numerous responsibilities simultaneously, and we demand employees who can do the same. It makes us feel busy. It makes us feel as if we are using our time more productively. The actual effects of multitasking, however, prove these feelings to be nothing more than an illusion. And illusion is a weak foundation for results. Ready to build a real one?
What's happening in the brain when we multitask? Say you are working on a financial report. The phone rings, and you continue to work as you take the call. According to Dr. Sanjay Gupta, renowned neurosurgeon:
You're not actually doing both activities at the same time, in fact, you're diverting your attention from one part of your brain to another part of your brain. That takes time, that takes resources, that takes brain cells.
It's true that we can shift focus incredibly fast - as quickly as a 10th of a second. But, says Gupta, "the time doesn't matter as much as the bandwidth the brain requires to move back and forth." This shifting can decrease productivity by as much as 40 percent. Even worse, quality suffers, and multitaskers are much less likely to engage in creative thinking than their monotasking counterparts.
Multitaskers face another major disadvantage. UCLA's Dr. Russell Poldrack says, "Even if you learn while multitasking, that learning is less flexible and more specialized." In other words, you cannot as easily apply your learning to new situations or use it in different ways.
If you guessed "multitasking," you're right. Researchers from the Institute of Psychiatry at the University of London found that multitasking with electronic media caused a more precipitous drop in IQ (15 points, putting you somewhere in the range of an 8-year old child) than smoking marijuana or losing a full night's sleep.
Ironic, considering job ads rarely call for "pot smokers, insomniacs, and 8-year old children only," while those saying "only multitaskers wanted" are fairly common. They shouldn't be.
Stanford's Dr. Clifford Ness, who has studied the topic extensively, says, "People who multitask all the time can't filter out irrelevancy. They can't manage a working memory. They're chronically distracted." In short, Ness concludes, they're "pretty much mental wrecks."
Study after study affirms that multitasking makes us less effective, reduces productivity, increases mistakes and distraction, and costs $450 billion annually. Another irony: we multitask because we believe it will make us more - not less - effective.
Effective multitasking is possible only when one of the tasks is automatic: e.g. walking and chewing gum. Add anything more challenging to the mix - listening, responding to clients, giving feedback to subordinates, crafting communications, browsing websites, checking email, etc. - and you have an unproductive, time-wasting mess. How do you start to clean it up?
A few tips:
You may pride yourself on your ability to multitask - but wouldn't it be better to pride yourself on enhanced productivity and stellar results? Quit the habit, embrace monotasking, get more done. And get it done better.
