Is it Possible to Multitask? 12 Reasons Why You May Not Want To

Is it Possible to Multitask? 12 Reasons Why You May Not Want To

There hasn’t been a busier time in the history of mankind than today’s fast paced digital world. Every day, we’re constantly barraged by an infinite stream of information, emails and social media notifications, whilst trying to keep up with demands from work, family and friends .

Our response to this overwhelm has been to do more than one thing at a time. We respond to text messages, whilst completing important projects, send emails, whilst watching TV shows and scroll through social media feeds, whilst chatting with friends and family.

But is it possible to multitask in this way? Even though it may seem like we’re getting a lot done, multitasking could cost us precious time and energy.

Here are 12 scientific reasons why you should stop multitasking today.

1. Multitasking kills productivity.

Each time we switch from one task to another, there’s a cognitive cost that hurts our productivity.

According to Gloria Mark, professor in the department of informatics at the University of California, it takes an average of 23 minutes and 15 seconds to get back to a task after an interruption.[1]

We’d like to think that it’s possible to juggle multiple tasks at once, but it comes with the cost of reducing the quality and quantity of attention applied to a task.

As a result, your productivity is less than that of someone who focuses on one task at a time.

2. Multitasking could endanger your life.

There are certain situations where multitasking may endanger your life.

For example, chatting on the phone whilst driving, or texting whilst crossing a busy road, could significantly compromise your ability to maintain safety.[2]

Multitasking isn’t worth your energy, time and especially, not your life.

3. Multitasking could damage your brain.

A study by researchers from the University of Sussex (UK) compared the amount of time people spent on media devices, like texting and watching TV to their brain structure.[3] The MRI scans of their brains showed that participants who multitasked more often had less brain density in the anterior cingulate cortex, the brain region responsible for empathy and emotional control.

According to the lead researcher, Neuroscientist Kep Kee Loh:

“I feel that it is important to create an awareness that the way we are interacting with the devices might be changing the way we think and these changes might be occurring at the level of brain structure.”

4. Multitasking could make you dumber.

A study conducted by the University of London found that adult participants who multitasked experienced drops in IQ points to the average range of an 8-year old child.[4]

Imagine the effects of writing an important paper or email to a client whilst responding to texts on your phone. There won’t be much difference in the quality of your work and that of an 8-year-old child.

If you’re struggling to deliver high quality work on a consistent basis, make sure to eliminate distractions in your environment and avoid multitasking. This will help to raise the quality of your work.

5. Multitasking causes chronic stress and anxiety.

There are many causes of stress and anxiety but one of the major culprits is multitasking.

When we constantly switch between tasks, cortisol, a stress hormone, is released in our body. This hormone creates stress, tires us out and leaves us mentally fatigued.

Then, anxiety builds up and we act impulsively which creates more stress. And the cycle repeats itself, creating a constant state of stress and anxiety.

6. Multitasking worsens decision-making skills.

Multitasking also hurts yours ability to make good decisions. Switching tasks requires that you spend precious energy deciding what to do or what not to do.

For example, if you’re sending important emails to your boss whilst responding to text messages, you’d have to make decisions immediately:

How do I respond to this email? Should I respond to this text now? Should I take a break from work?

These decisions deplete your willpower muscles and causes decision fatigue, a psychological term referring to the deterioration of good decisions after making a long series of decisions.[5]

In addition, when an important scenario arises for you to practice self-control or delay gratification, you’re more likely to act on impulse. And you won’t have enough willpower to take effective action towards the important things in your life.

In effect, multitasking causes a downward spiral of bad decisions, that cost time, energy and money.

7. Multitasking hurts learning ability.

A study published in the journal Computers and Education found that on average, participants who used Facebook, whilst texting and doing schoolwork, had a lower GPA and grades, than those who didn’t.[6] According to the researchers, Reynol Junco and Shelia R. Cotton:

“Human information processing is insufficient for attending to multiple input streams and for performing simultaneous tasks.”

Quality attention is crucial for learning but multitasking reduces our ability to focus on a task at hand. As a result of low levels of attention, learning effectively is much harder than otherwise.

8. Multitasking kills your ability to focus.

According to neuroscientist, Daniel Levitin, when you multitask, parts of your brain reward you for losing focus and switching tasks, with a rush of dopamine. The same parts of the brain that help you stay focused on a task become trained to look for distractions.

And so, when you’re working, you’ll feel a restlessness to check your email, social media and search for a dopamine rush from something else.

Once multitasking becomes a habit, it becomes very difficult to break the cycle of the dopamine rush linked to lack of focus and low productivity.

9. Multitasking kills creativity.

Imagine this scenario:

You’re writing an important paper and then, an incoming email from a work colleague pops up on your phone. You stop writing and respond to the email.

When you return back to writing, your brain has just spent valuable energy refocusing on the task at hand that could have been used for creative thinking. As a result, not only have you wasted energy, but also creative juice for your work.

Creative thinking requires a good level of concentration and attention. The problem with multitasking is that innovative ideas that crossed your mind could pass you by if you didn’t stay focused.

10. Multitasking may reduce your emotional intelligence.

Emotional intelligence is the ability to identify and manage your own emotions, in addition to the emotions of others. In general, emotional intelligence includes core skills, like emotional awareness, the ability to apply emotions to critical thinking and problem solving and the ability to manage emotions.[7]

According to Travis Bradberry, emotional intelligence expert, multitasking may damage a part of the brain — the anterior cingulate cortex that is responsible for emotional intelligence, a trait found within 90% of top performers.[8]

Multitasking reduces the speed and quality of work, worsens concentration and attention to detail. Additionally, multitasking in social gatherings may be an indication of low self and social awareness, two crucial emotional intelligence skills for success at work.

11. Multitasking causes overwhelm and burnout.

Ever wonder why you feel constantly tired even after a good night of sleep or a long vacation?

The constant switching between tasks requires a lot of attention and energy. When your brain shifts attention from one task to another, the prefrontal cortex of the brain loses oxygenated glucose which is required for staying focused on tasks.

The more tasks you switch between, the more oxygenated glucose your brain burns. After a short period of time, you’ll feel overwhelmed and tired, because of the loss of nutrients in the brain.

12. Multitasking could harm health more than marijuana

New York Times bestselling author and Neuroscientist, Daniel Levitin, suggests that multitasking could damage our brains, even more so than smoking marijuana![9]

According to Levitin, the main ingredient in Marijuana, cannabinol, negatively affects the same receptors in the brain responsible for memory and concentration. And multitasking could cause greater cognitive losses.

Next time you’re about to multitask, think of the similar effects of smoking marijuana. If you wouldn’t use drugs whilst completing an important task, then why multitask?

Final thoughts

As you’ve read thus far, multitasking is a bad habit that has long-term harmful effects on your health, well-being and productivity. But there’s hope if you take charge of your life today.

When working on important tasks, eliminate as many distractions as possible including your phone, email access and people. Every day, create time blocks of 10 to 30 minutes for focused work. Take short breaks every two hours to recoup your energy and regain focus.

Most importantly, do one thing at a time and you’ll be productive for a lifetime.

What Is Creativity? We All Have It, and Need It

What Is Creativity? We All Have It, and Need It

Do you think of yourself as a creative person? Do you play the drums or do watercolor paintings? Perhaps compose songs or direct plays? Can you even relate to any of these so called ‘creative’ experiences? Growing up, did you ever have that ‘artistic’ sibling or friend who excelled in drawing, playing instruments or literature? And you maybe wondered why you can’t even compose a birthday card greeting–or that drawing stick figures is the furthest you’ll ever get to drawing a family portrait. Many people have this common assumption that creativity is an inborn talent; only a special group of people are inherently creative, and everyone else just unfortunately does not have that special ability. You either have that creative flair or instinct, or you don’t. But, this is far from the truth! So what is creativity?

Can I Be Creative?

The fact is, that everyone has an innate creative ability. Despite what most people may think, creativity is a skill that everyone can learn and hone on. It’s a skill with huge leverage that allows you to generate enormous amounts of value from relatively little input. How is that so? You’ll have to start by expanding your definition of creativity. Ironically, you have to be creative and ‘think out of the box’ with the definition! Creativity at its heart, is being able to see things in a way that others cannot. It’s a skill that helps you find new perspectives to create new possibilities and solutions to different problems. So, if you encounter different challenges and problems that need solving on a regular basis, then creativity is an invaluable skill to have.Let’s say, for example, that you work in sales. Having creativity will help you to look for new ways to approach and reach out to potential customers. Or perhaps you’re a teacher. In this role you have to constantly look for new ways to deliver your message and educate your students.

How Creativity Works

Let me break another misconception about creativity, which is that it’s only used to create completely “new” or “original” things. Again, this is far from the truth. Because nothing is ever completely new or original. Everything, including works of art, doesn’t come from nothing. Everything derives from some sort of inspiration. That means that creativity works by connecting things together in order to derive new meaning or value.From this perspective, you can see a lot of creativity in action. In technology, Apple combines traditional computers with design and aesthetics to create new ways to use digital products. In music, a musician may be inspired by various styles of music, instruments and rhythms to create an entirely new type of song. All of these examples are about connecting different ideas, finding common ground amongst the differences, and creating a completely new idea out of them.

What Really Is Creativity?

Creativity Needs an Intention

Another misconception about the creative process is that you can just be in a general “creative” state. Real creativity isn’t about coming up with “eureka!” moments for random ideas. Instead, to be truly creative, you need to have a direction. You have to ask yourself this question: “What problem am I trying to solve?” Only by knowing the answer to this question can you start flexing your creativity muscles. Often times, the idea of creativity is associated with the ‘Right’ brain, with intuition and imagination. Hence a lot of focus is placed on the ‘Right’ brain when it comes to creativity. But, to get the most out of creativity, you need to utilize both sides of your brain–Right and Left–which means using the analytical and logical part of your brain, too. This may sound surprising to you, but creativity has a lot to do with problem solving. And, problem solving inherently involves logic and analysis. So instead of throwing out the ‘Left’ brain, full creativity needs them to work in unison. For example, when you’re looking for new ideas, your ‘Left’ brain will guide you to a place of focus, which is based on your objective behind the ideas you’re searching for. The ‘Right’ brain then guides you to gather and explore based on your current focus. And when you decide to try out these new ideas, your ‘Right’ brain will give you novel solutions outside of the ones you already know. Your ‘Left’ brain then helps you evaluate and tune the solutions to work better in practice. So, logic and creativity actually work hand in hand, and not one at the expense of the other.

Creativity Is a Skill

At the end of the day, creativity is a skill. It’s not some innate or natural born talent that some have over others. What this means is that creativity and innovation can be practiced and improved upon systematically.A skill can be learned and practiced by applying your strongest learning styles. Want to know what your learning style is? Try this test. A skill can be measured and improved through a Feedback Loop, and can be continuously upgraded over time by regular practice. Through regular practice, your creativity goes through different stages of proficiency. This means that you can become more and more creative! If you never thought that creativity was relevant to you, or that you don’t have a knack for being creative… think again! You can use creativity in any aspect of your life. In fact you should use it, as it will allow you to to break through your usual loop, get you out of your comfort zone, and inspire you to grow and try new things. Creativity will definitely give you an edge when you’re trying to solve a problem or come up with new solutions.
