MULTITASKING, It’s Dangerous

In computing, multitasking is a concept of performing multiple tasks (also known as processes) over a certain period of time by executing them concurrently.

Professor Clifford Nass is known for his work on individual differences associated with multitasking.

In Summer 2009, He and his team of researchers gave 262 students questionnaires to determine how often they multitasked. They divided their test subjects into two groups of High and low multitaskers and began with the presumption that the frequent multitaskers would perform better. They were wrong. 

Nass was sure multitaskers had some secret ability. “But it turns out that high multitaskers are suckers for irrelevancy.” They were outperformed on every measure. Although they’d convinced themselves and the world that they were great at it, there was just one problem.

My personal experience as follows At the time of Scrum Training, We had and experiment to see the result of multitasking, there were 30 participants. Everyone was standing next to each other.

Activity 1: Call out alphabet A-Z by each participant one by one, it took 25 seconds to complete an assignment.

Activity 2: In second activity we played with two activities simultaneously First call out the A-Z & 1-10, let’s call variable 1 & variable 2 respectively, but now there was one anonymous person other than 30 participants who will be calling “Switch” at random. As he calls out Switch participants will stop the current variable and next participant will start/continue with the another variable. It took approximately 77 seconds to complete an assignment.

Let’s take one more example, many of you might have gone through. At last, I have gone through. 🙂

During Meeting, I often think, let me send an email to the client. I sent mail, and I forgot to attach a file. So I send third mail with the attachment explaining to him why the attachment wasn’t present at first mail. After everything I try to refocus on the meeting and I realized I hadn’t heard a question the Chair of the Board had asked me.


“Can you please repeat it again?”

You might think you’re different, that you’ve done it so much you’ve become good at it. Practice makes perfect and all that.

But you’d be wrong. Research shows that heavy multitaskers are less competent at doing several things at once than light multitaskers.

Multitasking is merely the opportunity to screw up more than one thing at a time.- Steve Uzzell
