What Gets Measured...


Every institution obsesses over what’s measurable, be it circulation numbers or page views or profits or students’ marks or whatever. And almost all of us have complained that this mindset leads to the problem that V. F. Ridgway expressed so well:
“What gets measured gets managed - even when it's pointless to measure and manage it, and even if it harms the purpose of the organisation to do so.”

Of course, at the heart of this measurement mania lies the fear of the alternative: if it can’t be measured, does it become subjective? And once things are left to subjective assessments, will it become a free for all, where the lazy, the incompetent, the charlatans and the smooth talkers take over?

As Siddhartha Mukherjee wrote in The Emperor of All Maladies, objectivity lies at the heart of everything that calls itself a science (quantum mechanics may feel like an exception since it straddles both objective and subjective worlds, but then again, it is insanely accurate when comparing theory v/s measured values, often within 10 parts in a billion!):
“Science begins with counting. To understand a phenomenon, a scientist must first describe it; to describe it objectively, he must first measure it.”

So guess which type of cancer treatment became the first “rigorous science”? Leukemia, or blood cancer. Why? Unlike other forms of cancer which couldn’t be measured in any way in the pre-CT, pre-MRI era, leukemia could be measured. And as Lord Kelvin once said:
“If you can not measure it, you can not improve it.”
The cancer doctors agreed with Kelvin, as Mukherjee writes:
“If leukemia could be counted… then any intervention… could be evaluated for its potency in living patients.”
As medical tech advanced and it became possible to measure many things in the body, cancer treatment could track other numbers. So much so that Mukherjee describes this one doctor:
“To Li’s annoyance, (the hcg level) hadn’t gone all the way to normal… So despite every indication that the tumours had vanished, Li reasoned that his patients had not been fully cured. In the end, he seemed almost to be treating a number rather than a patient.”

Remember that saying about confusing the map for the terrain? Likewise, we often confuse what can be measured with what we wanted in the first place, but the alternative doesn’t seem very appealing and has its own downsides, so where does that leave us…

Student of the Year

Image
As a toddler, my daughter loved Alia Bhatt’s songs, esp. the ones from Student of the Year . (That movie did have many good songs and well-choreographed dances). Fast forward to present day, when she is 12 yo. She rarely watches Hindi movies now, but one of the few ones she likes of late, Raja aur Rani ki Prem Kahani has, yes, Alia Bhatt.   If I had any hopes that there was anything to be read in the name of her toddler-time favorite ( Student of the Year ), they have been dashed. Our conversations come exam time are perfectly captured by this photo and its caption: In fact, the pic below captures how she and I look at her answer sheets – me intently, she with an expression of “It’s over, so why are you even looking at it?”   Of late, we pull her leg and tell her that she isn’t showing any signs of academic prowess, she’d better find a rich guy to marry. Some time later, she showed us this meme on the Internet: “Me No Study, Me No Care Me Go Marry Millionaire If He Die

Animal Senses #7: Touch and Remote Touch

Instinctively, we think touch is based on contact. Not entirely true, explains Ed Yong in Immense World – there’s a more important aspect than contact: “These incredible feats are possible through movement. If you rest a fingertip upon a surface, you can get only a limited idea of its features. But as soon you’re allowed to move, everything changes. Hardness becomes apparent with a press. Textures resolve at a stroke.” As you run your fingers over a surface, they hit the tiny peaks and troughs and set off vibrations in the mechanoreceptors at their tips.   At the tip of its snout, the star-nosed mole has many pairs of hairless appendages. It uses them to touch things around itself. Alive or dead? Food or ignore? It does these movements at an insane speed. In the time it takes to blink our eyes, the star-nosed mole can probe, identify and swallow its food. “Light may be the fastest thing in the universe, but light sensors have their limits, and the star-nosed mole’s sense of

The Retort of the "Luxury Person"

Image
Coming up with biting and witty retorts. It’s something we dream of, but rarely manage to pull off. Worse, the more we stew over the offending remark, the more likely we are to come up with that dream retort, as Calvin ruefully points out: During our last holiday at the Taj Resort, seeing my wife carrying towels to our poolside chairs, one of the kids there mistook her for a member of the staff and asked for a towel. When my wife narrated this to us, I did not imagine that my 8 yo daughter would come up with her own retort. But a day later, my daughter recapped the incident, an incident that didn’t even involve her in the first place , and said, “You know what I’d have told that kid who asked for the towel?”. And without waiting for an answer, she told us anyway: “I don’t work here. I too am a luxury person who is living at this resort. Go get your own towel.” We were highly amused by the phrase she had coined: “luxury person”. It certainly captures the kind of holid
