box, business, celebrate


Around a decade ago some employers suddenly started to ask during work interviews: Are you able to multitask? Some still do this although many people are already familiar with the most recent studies which indicate that multitasking is impossible in humans and is merely switching from one task to another. On top of that, multitasking decreases productivity by up to 30-40%.

It may sometimes be okay to combine a physical activity with a cognitive one, e.g. listening to an audio book while riding a bike or washing dishes, but many employers got the idea of multitasking completely wrong. Some of them believe that multitasking is needed and can be done in busy office environments where one needs to answer a lot of phone calls, reply to emails and provide face-to-face customer service. No, it can’t.

Research shows that trying to multitask will actually make you slower and also … lower your IQ! Our human brain can focus only on one task at a time and people who try to work this way and avoid multitasking achieve the best results.

Researchers from the University of Sussex in England carried out a study using MRI scans. The findings revealed that people who spend time using multiple devices, for example texting while watching TV, had less brain density in a part of the cortex which is responsible for cognitive and emotional control. Emotional control is a simple term but some of you may wonder what cognitive control means. It basically means that your brain allows you to make decisions based rather on our goals than habits and reactions. It allows you to be flexible and adapt more easily in different situations.

If you are interested to read more about multitasking I’d recommend this book: The Myth of Multitasking: How “Doing It All” Gets Nothing Done by Dave Crenshaw (available here).

    1. I think yes sometimes we have to multitask a bit even if we dont like it/dont want to do it (especially women who try to do so much all the time and juggle so many different things at once) but it is exhausting and it’s better if employers dont expect it form us. Its not healthy or beneficial in anyway in the long term..
