Book Review: The Drunkard’s Walk by Leonard Mlodinow

Sitting at a bar, Sharmila said “I am having difficulty reading this book for my book club”
“Is it very violent or too dense?”, I asked
“ I can’t follow it at all”
“What is the name? What is the thesis?”
“The Drunkard’s Walk”.
“Oh! In statistics, that is a common problem discussed. If a completely drunk man could take a step east, west, north or south at every step randomly, after “n” steps, what is the chance he is back to his original spot?”
“That is what the book is all about. Chance. Probability.”
“That is my kind of book. Why are you reading it?”
“Well, Seemita-di chose that book”.

Without any fear or favor, I immediately started reading that book since she had already paid for it.

You know how there are certain kind of books that you relate to immediately? For me, it is the genre of human behavior, behavioral economics and so on. But when you put that with Talent in the corporate sector, you have topped it up like you cannot any more.

Few things bristle me more than people who think they understand talent and can predict what kind of talent can cause success. What bristles me precisely is the assumption of determinism and not realizing how much luck or chance plays in the outcome. Little surprise that in get togethers of ex employees of an old startup that succeeded spectacularly before crashing equally spectacularly (and I was fortunate enough to have gone thru the journey) I stick out as a sore thumb when I point out that chance was a bigger factor in our success rather than somehow we had the most brilliant people in this earth and that we suffer from nostalgia when we wipe out all the failures we had on our way to success and then the spectacular burn out.

This book, if not anything, bolstered the basis of my thoughts. Did I mention, I love this book? 🙂 (Psychologists will call it Confirmation Bias 🙂 🙂 )

In summary, the book endeavors to explain how chance plays an outsized role in our personal and professional lives and of all the things we take into account explaining or predicting performance, that is the one thing we do not talk about.

Some quotes from the book:

1. When (Sports) teams fail, the coach is often fired. Mathematical analysis of firings in all major sports, however, has shown that those firings had, on average, no effect on team performance.
2. If the details we are given (of anything) fit our mental picture of something, then the more details in a scenario, the more real it seems.
(RR notes: I can see this in the postings of my Dem and Rep friends on the two Presidential candidates daily in my newsfeed)
3. Availability Bias: In reconstructing the past, we give unwarranted importance to memories that are most vivid and hence most available for retrieval
(RR notes: This is part of the startup recollection)
4. We associate randomness with disorder.
(RR notes: In reality total randomness is actual perfection – it can never be reached)
5. When we look closely, we find that many of the assumptions of modern society are based on shared illusions.
6. There is a fundamental clash between our need to feel we are in control and our ability to recognize randomness. That clash (of control versus helplessness) is one of the principal reasons we misinterpret random events.
7. Not only do we preferentially seek evidence to confirm our preconceived notions, but we also interpret ambiguous evidence in favor of our ideas.
8. “Chance is a more fundamental conception than causality” – Nobel laureate Max Born
9. We cannot see a person’s potential, only his or her results, so we often misjudge people by thinking that the results must reflect the person.
10. But ability does not guarantee achievement, nor is achievement proportional to ability. And so, it is important to always keep in mind the other term in the equation – the role of chance.

A powerful message from Rory Sutherland

I am sure you too, like I, have a few people that you look forward to talking to. For me, they tend to be folks who have great wisdom that I can learn from. Most are younger than me but ways ahead of me in terms of questioning commonly accepted social norms, fearlessness in crafting their own ways, sheer independence in thinking and the ability to argue two sides of an argument.

Today was such a person’s birthday – Uttara. We spoke for the better part of half an hour and I came away re-inspired to question everything that I do and get a deeper understanding of my own biases. We talked a lot about the default mode we set ourselves in when it comes to spending the most valuable and the most personal assets we have – our time, our body and so on.

Right after that talk, I went for a run and put on a talk by Rory Sutherland on my Airpods. Usually, after about 5-10 minutes, I get into the mood of running and tuck away my phone and Airpods in the waist pouch. Today, though, I got hooked on to the message. So much so, I listened to it twice during my run and then drive back home.

Here is the link: https://www.youtube.com/watch?v=Bc9jFbxrkMk

Uttara, if you are reading this, you might find an interesting take he has, and some counter intuitive research studies on work commute!!

Early morning sitting out

Our neighborhood has a lot of nature and sitting spots around trails, parks etc. Given that temperatures are starting to cool off, these days, instead of practicing mindfulness with a cup of cappuccino in our balcony, I walk to one of the benches and enjoy the breaking of dawn. The cicadas and the birds provide most of the background noise. Plus some last few frogs who have not retired yet. The glistening of sprinkler water on the long blades of grass look beautiful.

Want Jay Jay to join me too but he is too deep in his sleep this time of the day.

This be my 10,000th post

What started way back in 2005 as an experiment to write down my reflections from job life during one of those year offs, soon turned out to be a journal for writing down the small details of life as I was experiencing them. From all those strangers I met during my travels, those chance meetings, the quirky hobbies, those poems and their translations, those math and map puzzles, the books I read… a lot of tiny bits of memories are engraved in this blog (https://www.rajibroy.com).

Some day, when I lose most of my physical abilities, hopefully reading the posts will serve as a powerful reminder of what a great life I had.

May be, progeny will read this and get a glimpse of what life looked like for one ordinary and uninteresting person. While chuckling at how archaic this old technology called “internet” was!

Book Review: Caste by Isabel Wilkerson

It is a hard hitting book. I had suggested this book to a dear Caucasian friend of mine. Whose reaction after reading the first couple of chapters was that it was a politically motivated book. Surprised by the feedback, I asked him to keep reading on. A couple of weeks later, I was getting constant text messages after every chapter about how he has completely changed his mind.

This book will hit you at some of your core beliefs. It dissects Caste-ism. The common misconception is that caste is an India thing. The author convincingly establishes that caste has been most prevalent – written in law, practiced but the people and enforced by the upper caste people in three areas – India, Nazi Germany and America.

The American reference was the most jarring. The author establishes how “race” was the way casteism was established in America. In fact, it quickly shows how the concept of “race” – as in white or black is arbitrary and makes no sense when you go outside of America. Did you know that there was a court case about whether Indians should be considered white or not (due to Aryan descent and what not)?

The reason for caste is neither feelings not morality. It is about power and resources – which groups will have it and which groups won’t.

Frankly, it opened my own eyes to Dalits in India. Growing up in India, we were never taught about how we treat Dalits. If anything, we were taught about how in the past “harijans” were mistreated. Today, reading news about the crimes against Dalits in modern India, I have a renewed understanding of the insidious nature of subjugation that casteism has wrought in a few societies.

Read this book only if you feel you are open enough to be questioned hard on some of your core beliefs. Else, give it a pass.

I loved the bus journey. The train? Not so much!

The good news is that I got 10 hours of road time with Niki. The bad news is that means my car is still sitting at the airport. Instead of bothering Sharmila and Nikita to take me there, I decided to change up my life a little and take public transportation.

Had to start from the very basics – like downloading the app to catch a bus and all that. The bus stop is about a couple of minutes walk from my house. Loved that journey. This is the second time I took MARTA bus. Being able to see all the familiar scenes, except now I am much higher and have long glass window panes was inexplicably exciting. Experiencing the bus stop to drop off or pick up a passenger and even watching how each passenger go thru the decisioning process of which seat to take was strangely enjoyable. But the best part was speeding down the highway!!!

The train journey – which should have been even more interesting – was marred by the fact that I quickly became queasy. Both Niki and I suffer from car sickness. One of the rare times when I had taken Marta train in the past, it was so bad that I had to get off at a station and take the next one after stabilizing myself.

Maybe I should go around in the buses randomly just to … you know, ummm…for no particular reason at all.

By the way, the street you see in the picture is where I live.

An evening with music and tabla

My school friend – Sanjay Saha – recently introduced me to the Bangla Band – “Joler Gaan”. I did not know of them. But very nice renditions of Bengali folks songs.

পরের জায়গা পরের জমিন, ঘর বানাইয়া আমি রই
আমি তো সেই ঘরের মালিক নই

“Porer jaga porer jomin, ghor banaiya aami roi
Ami to sei ghorer malik noi”

The folk song muses that nothing is really ours. We build “our” house on “our” land… and yet, nothing really is “ours”.
