The Making of a Dumb Datum

Imagine 10,000 years in the future. Two archaeologists are digging a site, and they find the remains of human bones. They take those remains to the lab, perform tests on them, and try to reconstruct the habits and lifestyle of that human. Say those bones belong to me. They are trying to find out my story, how I lived, what I ate, where I traveled, etc. Once they find all the info they need, they toss it into a museum where they store all other such ancient human remains they find. I was essentially one data point to them in trying to understand how humanity evolved over time. Or I can also call myself a “datum”, the singular form of data, literally one piece of information to solve a bigger puzzle. Honestly, I don’t need 10,000 years to become a datum. I am already a part of several datasets people use these days to study many things. So for that objective learner, I am already a datum. Now let me get to how I got the dumb part of it. I have had an interesting and eventful life so far...

Irresponsibility

I think about this one story I read about Feynman a lot, especially during the times when I am going through burn out in my personal and professional life. I am unfortunately not blessed with a good memory, so I am fairly certain I get many facts wrong in it, but I can recall its essence very accurately.

After Feynman was done working on atomic bomb during the war, he was offered a hot shot professor job in some big school, Cornell, I think. And he kept getting better offers from all other places because everyone wanted a piece of him. But he was also depressed and burnt out. He worked in a very intense environment in Los Alamos for atomic bomb, and around the same period, love of his life and his first wife, Arlene died due to sickness. So later when he started working in Cornell, he was barely scraping by at work, and he spent time reading Arabian nights (early version of doom scrolling).

He felt guilty and he felt like a fraud, because all were saying wonderful things about him, and had high expectations on his work, whereas he lost all his curiosity and motivation. He spent a good amount of time in that state, with a deeply conflicted mind.

Then one day, he was shaving in front of the mirror, and a beautiful thought occurred to him. He asked himself what’s the worst that could happen if he doesn’t meet other people’s expectations. He never asked them to keep those expectations in the first place. So, he is not responsible for fulfilling them. This thought surprisingly freed him, and he went back into just playing with physics, the way he always did ever since he was a kid.

Later he was in cafeteria, and saw a kid throw Cornell medallion in air, and he noticed something interesting about the movement of medallion and the plate. He got excited, worked out the equations, and figured out that the medallion rotated roughly twice as fast as the plate wobbled. He told his colleague about this finding, and this colleague was like “okay, this is great, but what’s the point of this?” To which I believe Feynman replied with “there’s no point, I am just doing it for fun.”

But this discovery apparently laid foundation to the work that ultimately got Feynman his Nobel prize.

What is SUTVA for A/B testing?

Imagine if person B’s blood pressure reading depends on whether person A receives the blood pressure medicine in a randomized controlled trial. This will be violating Stable Unit Treatment Value Assumption (SUTVA) SUTVA states that the treatment received by an individual should not influence the outcome we see for another individual during the experiment. I know the initial example sounded absurd, so let me try again. Consider LinkedIn A/B testing a new ‘dislike’ reaction for its users, and the gods of fate chose you to be part of the initial treatment group that received this update. Excited after seeing this new update, you use this dislike reaction on my post and send a screenshot to a few of your connections to do the same, who are coincidentally in the control group that did not receive the update. Your connections log in and engage with my posts to use this dislike reaction, but later get disappointed as this new update is not yet available to them. The offices of LinkedIn are tr...

Solving Customer Churn with a hammer!

Learning when data should take a back seat and give way to domain knowledge is a valuable skill. Suppose you built a machine learning model on the data of your customers to predict churn risk. Now that you have a risk score for each customer, what do you do next? Do you filter the top n% based on the risk and send them a coupon with a discount in the hopes that it will prevent churn? But what if price is not the factor driving churn in many of these customers? Customers might have been treated poorly by customer service, which drove them away from your company's product.  Or there might have been an indirect competitor's product or service that removes the need for your company's product altogether (this happened to companies like Blockbuster and Kodak in the past!) There could be a myriad of factors, but you get the point! Dashboards and models cannot guide any company's strategic actions directly. If companies try to use them without additional context, more often tha...

Curing writer's block with sunk cost fallacy

I paid $20 to renew this blog's domain in July. But the truth is, I had been suffering from writer's block ever since the start of this year and hadn’t posted a single thing. At one point, I was ready to give up on the blog altogether, but a voice in my head kept reminding me of all the time and money I’d already invested in this blog. So, this week, I sat down to write this imperfect, patchy article—about none other than that voice itself.  Let me start with a classic scenario where you might have also encountered this voice. Suppose you’re at an Italian restaurant and ordered some pasta and tiramisu. After finishing the pasta, you realize you’re full, and there’s no way your stomach can handle that delicious tiramisu sitting right in front of you. But then, that beautiful brain of yours reminds you that you’ll be paying for the tiramisu whether you eat it or not. In a desperate attempt to avoid wasting money, you reluctantly eat two quick bites. And just like that, my frien...
