Is Multitasking Still a Skill to Boast About?

Multi Tasking Cartoon

Over the last 4-5 years I have read many articles (popular as well as academic) that have consistently tried to educate people that multitasking is inefficient, error-prone and negatively impacts the mental health of the so-called multi-tasker.

However, we still receive job applications with resumes that highlight the multitasking skill of the applicant. So, I chased this a bit, and discovered that even consultants helping people apply for jobs advice them to highlight their multitasking skills (or is it a single skill?). I have also found ‘multi-tasking skill’ as a checklist item in the interview evaluation forms of a few organizations.

Evolution of the Multitasking concept

The word ‘multitasking’ first appeared in the description of the capabilities of an IBM computer (System/ 360) in 1965. People started using the word for human beings in the 1980s as a desirable skill and something that enhances productivity.

So, what is multitasking in human beings?

Human multitasking is the apparent performance by an individual of handling more than one task, or activity, at the same time. The term is derived from computer multitasking.


In the last ten years, multiple controlled experiments and studies have been conducted to understand the concept of multitasking in humans. The research consistently shows that humans cannot pay attention to multiple things at the same time. So they are essentially doing rapid context switching. This increases the total time taken and also increases the errors. People who typically multitask, perform poorly (compared to people who do not typically multitask) even when they are asked to do tasks sequentially.

Multitasking is Not Recommended

So, unless it is absolutely necessary, do not multitask (I am using the word multitasking as is commonly used – actually it is some kind of rapid context switching). And do not take pride in your multitasking. Here are a bunch of reasons:

  1. It could be dangerous – like talking on the phone while driving, or texting while walking on a busy road. In some professions, trying to simultaneously do more things than what is absolutely required may be fatal to others (surgeons, air traffic controllers, pilots, etc.).
  2. It is slower and less efficient. According to some studies productivity can reduce by around 40% when you multitask.
  3. It is error-prone. Research consistently shows that people make more errors while multitasking. So, the tasks that you get “First Time Right” reduce significantly.
  4. There is no sense of satisfaction of completion, because there are multiple tasks in progress, and the sense completion of one task  is overshadowed by the rest of the ‘work-in-progress’.
  5. Communication becomes unclear and unsatisfactory – in professional and personal life. Because you cannot pay continuous attention to what others are saying. Nor can you convey a complete concept that requires long communication. This could impact relationships too.
    For example, because you were on the phone while typing an email, you may mark the email to the wrong persons, or send the email with partial / wrong information – thereby creating confusion that needs further communication and sorting out.
  6. Multitasking increases stress. When we start to drop balls,and make mistakes our feeling of overwhelm increases, and the stress keeps building.
  7. Multitasking reduces the IQ (temporarily) by around 10 points – roughly equivalent of missing one night’s sleep – for people who are already sleep deprived or already have a low IQ, it may be a disaster :-).
  8. Multitasking becomes more difficult with age. As all of us are ageing at the same rate (1 day per day, 1 year per year), we will be able to do less and less of ‘multitasking’ as time flies.
  9. Multitasking while eating can make you overeat – so it is not aligned with healthy eating.
  10. Need to multitask may be addictive – you may be soon be unable to focus on a single task for a long duration, even if that is essential (like answering a 2 hour examination without your cellphone or tablet or laptop or TV or favorite book).


Here are some aspects of multitasking for which I could not get very definite answers.

  • Does gender play a role in the ability to multitask?
  • Are some individuals significantly better than others at multitasking?
  • Does multitasking reduce attention span? Or do individuals who lack attention span typically tend to multitask?
  • Can we train people to be good at multitasking?
  • Are there some combination of tasks that are conducive to multitasking? What are their characteristics? (For example – it is perfectly natural to speak to someone seated in a car while you are driving, but not to speak on the cellphone;  one can listen to music and answer emails, but one cannot cook while answering emails).

Here are some good, easy-to-read books that explain more of the concepts and can also help you manage the situation better:

“My Bad” and its nuances

I first heard the term “my bad” many years ago. After my initial puzzlement, I figured that it was a new way of saying “my mistake” or “I am sorry”.

Over time I have realized that “my bad” is subtly different from “I am sorry”.  “My bad” is usually accompanied by a casual flick of the wrist and a sardonic smile. If the head is full of bouncy hair, there also the optional toss of the head.

It is like the person is saying, “I have apologized, now don’t make a fuss about it.”

I suspect (without actual data), that many folks rehearse saying “my bad” in front of a mirror. They also deliberately make the minor mistakes in their work,  or practice spilling coffee on the others – just so that they can say “my bad” in style.

I believe that the Corporate Communication team of a large organization is soon going to release a policy and guidelines document on the use of “my bad”. This is likely to be copy/pasted across the world eventually.

More to be done:

  • Clarity on the use of  derivatives like – “my worse” or “my badder”? “my worst” or “my baddest”?
  • Whether performance appraisal systems/ forms need to be modified to reflect the new terminology (what were your bads in the last period?)
  • What are the equivalent terms in other languages and regional variations in those languages (e.g., the Hindi equivalent in Delhi is likely to be different from the Hindi term used in Lucknow)
  • What is the historical origin of the term? Some say it is “my bag”.

I think I have gone on too long already – my bad!

Your comments are absolutely essential to make progress on the matter.

Cartoon: Lifetime Warranty ~ Whose Lifetime is it Anyway?

Cartoon: Lifetime Warranty ~ Whose Lifetime is it Anyway?

Recently we went on a project to evaluate and buy a household appliance. Part of the sales pitch that we heard repeatedly was about warranties, with the phrase ‘lifetime warranty’ finding its way in the spiel.

I can understand the concept of warranty for a period of time (1-year, 2-years, etc.), but the concept of ‘lifetime warranty’ has me confused  — I am not sure of whose ‘lifetime’ the warranty is valid for. For example:

  • Is it the lifetime of the buyer? What happens if the buyer dies and the item is inherited by someone else? Does the warranty hold?
  • Is it the lifetime of the retail shop or the retail chain? What happens when the shop/ chain shuts down or is acquired by some other entity?
  • Is the warranty valid only as along as the item continues to function (live) – and the warranty expires as soon as the item stops functioning (dies)? In which case there is no warranty.
  • Is the warranty valid only as long as the model continues to be produced?
  • Is it valid for the lifetime of the manufacturing company? Or manufacturing facility?
  • Is it valid only as long as the technology used is not obsolete? For example, can I claim the lifetime warranty on my floppy disk drive? (I may need to retrieve some of the data backed up in a floppy disk).

There are many more ways that ‘lifetime’ warranty can be interpreted.

But I leave that to your imagination. Please do share your interpretations in the in the space provided below for comments.

By the way, there may an opportunity for a start-up to provide extended lifetime warranties (on an app, of course 🙂 ).

Cartoon: New Revenue Source for Bangalore Traffic Police

Cartoon: Slaves to Measurement

According to sources not willing to be identified, Bangalore traffic police is toying with the idea of imposing ‘invalid parking’ fine on all vehicles that are halted in traffic jams. The consulting firm that suggested this initiative projected that the annual collections will shoot up between 10.3 – 12.4 times their current collections.

It may also motivate the drivers who get stuck in jams to find innovative solutions to avoid traffic snarls.

Pilot / trial implementation may have already started.

This idea surely beats the Delhi ‘odd-even’ solution to manage traffic.:-)

Bangalore Traffic is also planning to use this initiative to apply for the ‘Most Jugaadu Innovation of the year’ award instituted by Daily Jugaad.

Increase Chances of Becoming a Donor (organs/ body)- Take Action Now!

Organ Donation LogoAugust 13, 2016 is being observed as the Organ Donation Day in India.

Briefly, one can donate tissues, organs and the whole body. Donations can take place under three circumstances:

  1. Donations when alive and conscious. Examples of these include blood, stem cells, bone marrow, kidney (only one), and segments of liver, pancreas, lung, or intestine, and are limited by what can be given without affecting the health of the donor.
  2. Donations when ‘brain dead.’ These include organs that can be transplanted such as heart, liver, pancreas, intestine, 2 kidneys, and 2 lungs. Tissues such as corneas, bone, skin, heart valves, tendons, and veins can also be used.
  3. Donations within a short time of typical death. Some organs/ tissues can be used for others, for example corneas harvested within a few hours after death can be used to give sight to someone. You can also donate any part of your body — like the brain — for research and use by the medical community. Finally you can donate your whole body to a medical college, usually to the anatomy department, so that students can study it and gain experience.

You may be very keen to donate, but you are not the person who will be taking action and doing the donation once you are dead (or brain-dead). Someone else, usually one or more of your close family members will be performing the actual actions required for the donation. Enrolling in donor’s lists may make you feel you are a “donor”, but the deed is not done until the organ or tissue is removed at the right time.

So, what should you do now (before you are brain-dead or dead) to increase the chances of successful donations? Here is a list of things that you can do:

  1. Discuss your desire to donate in detail with all your close family members. Convince them and ask for their commitment to help this happen when you are dying or are dead. Be persuasive. Explain to them what to do in case of brain-death and after death.
  2. Document your desire clearly. Write down your wish to donate (like a will), sign it, and make copies. Give copies to your close family members. Put copies in important files. Laminate a copy and hang it at home, where it is visible. This writing down will remind your loved ones of your desire. It will also make it easier for them to cope with doubts or criticisms that others may have regarding their actions relating to the donation. And who knows, it may inspire others too.
  3. Make the donation easy for your family after your death. Make sure the correct and up-to-date actual contact names, organization names, phone numbers and addresses that are required for performing the donation are readily available and that the family members know about them. Write down a possible sequence of activities to be done.

Enrolling yourself as a potential donor with different organizations is a good first step. But remember that these organizations will not know of your death or brain-dead status when that happens (nor will you be in any state to inform them :-)). Finally, your family members have to decide to donate or not, even if you have signed up as a potential donor.

So you need to be more proactive to actually increase the chances of becoming a donor. Inform your family members, convince them and make it easy for them to perform your desired donations. This may be more important than signing up a with a lot of organizations and collecting their badges, t-shirts and enrollment cards.

By the way, your family members can donate your organs/ tissues/ body even if you are not enrolled :-).

Many basic concepts related to various types of donations, and also information on the various steps and procedures can be seen at this link:  FAQ on Organ/ Body/ Brain/ Eye Donation. Additional comments are available at: Voluntary body donation: some thoughts in response to queries I get.

Why is the CVV Number Printed on Credit Cards?

The CVV number is a 3 or 4 digit number (associated with a credit card) that is used for verification in case of Card Not Present (CNP) transactions. CVV stands for Card Verification Value and is also called Card Security Code (CSC), Card Verification Code (CVC), Verification code (V-code or V code), and Signature Panel Code (SPC).

Card CVV Number

CVV numbers are used to authenticate the card, as an additional security measure when the card is used in online transactions. It is like an ATM pin.

I am unable to understand why the CVV number is printed on the card, whereas the ATM pin is provided to the card holder separately.

Every time the credit card is used (for swiping), the staff at the outlet have access to the card. They can copy/ remember all the details on the card and later the same details can be used to place online orders. Also, if the card is stolen, the thief has most of the details necessary to place online orders on many shopping sites.

Printing the CVV number on the card is like printing the ATM Pin on the card.

So, can someone please throw some light on why the CVV numbers are still being printed on credit cards, while the same card companies are resorting to sophisticated security systems to prevent fraud?

In the meantime, all of us may be safer if we smudge the CVV numbers from our credit cards.

By the way, the cards shown in this post are not mine :-).

Recycle Greywater to Reduce Urban Water Needs

Some weeks ago, there was a buzz in our residential complex about having to set up “grey water” processing, because it may be made mandatory by the municipality. I got curious and started investigating the topic.

At the end of my study I was left wondering why it was not yet mandatory – grey water processing, when fully implemented, could reduce the water requirements in cities by 30-35%!!

“Life Mantras” – by Subroto Roy – I’m Not Joking!

Some time back, I was surprised  to see a philosophical book by Subroto Roy at an airport book stall. It was titled “Life Mantras”.
Life Mantras

I believe the book was launched in ‘absentia’ of the author (who was in jail) with many heavyweight celebrities and politicians (the launch had heavyweights, the jail also had heavyweights). There were, of course, Sahara employees who hoped for some announcement about their pending salaries, commissions, and bonuses.

The book is published by Rupa, is priced cheap and available easily.

I hope the book generates some of the money that Sahara has to deposit with the SEBI :-).

Maybe, now Vijay Mallya will be inspired to write a book titled “The Greatest Escape“?

Or, the political parties’ high-command can write “Win Some, Lose Some Lose Some, Lose Again” (you can guess which parties).

Choosing a Home Water Purifier in Bangalore, India

Water Purifiers
A few months ago, it was time to replace the water purifier at home. The present one was difficult to maintain – the model was discontinued and its replacement parts were no longer available.

We thought it would be a simple task of selecting from one of the popular brands (like Kent or Aquaguard).

Little did we know that it would become a whole big project that required deeper research and evaluation of many alternatives based on criteria. Our task was made easy by the details available at achawater.com – a comprehensive site that covers water purification in great depth.

Typical impurities that need to be removed

As the first step we had to figure out the possible impurities to be removed. Our water is supplied by the municipality in Bangalore (BWSSB).

Here is a list of possible impurities in this water.
