The Problem With a Common Engineering Entrance Test

… is correlation and concentration.

Like everything else, a student’s performance in a test can be divided into two – the predictive component (which can be explained based on preparation levels, general intelligence, ability to handle pressure, etc.) and the random component (which includes and is not limited to illness on the day of the exam, reaching the venue late leading to unsettlement, pure luck (or the lack of it) and so on).

Now, when you have a number of exams, what you expect is for a student’s “random component” to even out across these exams. If he outperforms his “predictive component” in one exam, you would expect that he would underperform in another exam. It’s like the “predictive component” of his performance is the expected “value” of his performance.

Thus, when you have a large number of entrance exams, it gives students the opportunity for their random components to even out, and take luck out to some extent from their college admission process. When you collapse all entrance exams into one, however, a student who happens to get a large negative “random component” on that given day is denied a second chance. Thus, the college admissions process will become much more of a crapshoot than it is now.

The other thing about uniform admission standards is why should every college have the same requirements for the students it wants to recruit? Having a common exam forces this upon colleges, unless they are allowed to change their weights allocated to different sections differently. If this doesn’t happen, it’ll only end up bringing all of the country’s education system to a uniform mediocrity.

The Trouble with Mental Illness

  • The “patient” has an incentive to overestimate the extent of his illness, since he can “get away” with certain things by claiming to be more sick than he is
  • People around the patient have an incentive to underestimate the extent of illness. They think the person is claiming illness only to extract sympathy and get away with things that would be otherwise not permissible
  • The second point here leads to internal conflict in the patient, as he can’t express himself fully (since others tend to underestimate). Feelings of self-doubt begin to creep in, and only make the problem worse
  • There are no laboratory tests in order to detect most kinds of “mental illness”. Diagnosis is “clinical” (eg. if 8 out of following 10 check boxes are ticked, patient suffers from XYZ). This leads to errors in diagnosis
  • The method of diagnosis also leads to a lot of people in believing that psychiatry is unscientific and some reduce it to quackery. So there is little the medical profession can do to help either the patient or people around him
  • That diagnosis is subjective means patients have incentive to claim they’re under-diagnosed and people around are incentivized to say they’re over-diagnosed
  • I don’t think the effect of a lot of medicines to cure mental illness have been studied very rigorously. There are various side effects (some cause you to sleep more, others cause you to sleep less, some cause impotence, others increase your mojo, and so on ), and these medicines are slow to act making it tough to figure out their efficacy.
  • There is a sort of stigma associated with admitting to mental illness. Even if one were to “come out” to people close to him/her, those people might dissuade the patient from “coming out” to a larger section of people
  • If you were to be brave and admit to mental illness, people are likely to regard you as a loser, and someone who gives up too soon. That’s the last thing you need! And again, the underestimate-overestimate bias kicks in.
  • Some recent studies, though, show a positive correlation between mental illness and leadership and being able to see the big picture. So there is some hope, at least.

Why Kannadigas are Inherently Lazy

There is something about the weather in Bangalore. There is something about the weather in Bangalore that perks you up. There is something about the weather in Bangalore that most of the time you really want to do something, to be active, to go out, walk around, lead an active life and all such. The first few days I spent in Bangalore after my return from Gurgaon in June I spent literally jumping around. The weather was so uplifting. It filled me with so much enthu for everything in life!

So I was wondering why people usually classify Kannadigas as being inherently lazy. As one of the professors in my JEE coaching factory used to say “naavu Kannadigarige aambode mosaranna koTTbiTTre khushhyaagiddbiDtivi” (if someone gives us Kannadigas dal vada and curd rice, we’ll live happily forever, and we will forget about working hard). Basically implying that we are inherently not too ambitious, and that we are generally laidback about stuff.

Thinking about it, I was wondering if the wonderful climate of South Interior Karnataka has to do with this (people from North Karnataka and the coast are supposed to be fairly hardworking, and are not known for their laidbackness unlike us Old Mysore people). I wonder if this laidbackness is because our wonderful weather has spoilt us. Spoilt us to an extent that we don’t really need to normally fight against the odds.

So I was thinking about Gurgaon, the other place where I’ve recently lived in. Gurgaon has horrible climate. Maybe a total of one month in the year can be desccribed as “pleasant”. Most of the time it’s either too hot or too cold. Temperatures are extreme. When it rains the whole place floods up. If people in Gurgaon are happy it is in spite of the weather and because of it. And therein lies the reason why people from there are traditionally more hardworking than us people from Old Mysore.

Blessed with such wonderful climate, we don’t really need to fight the odds. If today is too hot, we can put off the job for another day when we’re sure it’ll be cooler. If it rains too much today, we know that it’s likely to be dry tomorrow and can thus postpone it. Essentially we don’t need to put too much fight. When the weather is good, we are all jumpy and enthu and do our work. Which allows us to wait and sit when the weather is bad.

The man in Gurgaon, or in Chennai, or even in Raichur, however, can’t afford that. The likelihood of him having a good day weatherwise sometime in the near future is so thin that there exists just no point for him to postpone his work thinking he’ll do it when he feels better. This means that he is culturally (rather, climatically) conditioned to work against the odds. To do stuff even when he doesn’t want to do it. To essentially put more fight. And so he avoids that “inherently lazy” tag which people like us have unfortunately got.

I’m reminded of the second case that we did in our Corporate Strategy course at IIMB, from which the main learning was that sometimes your biggest strengths can turn out to be your biggest weaknesses.
