I’m not insane (I’ve only lost my mind)

Imagine that you are locked up in an insane asylum. You are perfectly sane, or so you think. In fact, you have lived your life with the assumption that you are normal. Now, you are stuck inside a mental ward because the doctors have diagnosed you with a very serious mental illness.

The doctors think that you have to be isolated from the rest of society because you have been identified as a threat. And society has willingly abandoned you.

Inside the ward, you struggle to come to grips with your helplessness. Because you have no legal rights as a human, your movement is restricted and you are deprived of privacy for even your most basic daily activities. The nurses and attendants have complete control over you. You are shocked that they go on with their business without ever talking to you or even noticing you. They even talk about you in front of you in degrading terms as if you are incapable of comprehension. You cannot change your situation or station in life. If you commit the “grievous sin” of talking to the staff without first asking for permission, you suffer a merciless beating.

Understandably, you are scared and nervous, but you also believe you will be released soon if you act normal. You go about your daily life trying to convince others that you are not insane. Unfortunately, your every act is perceived as a symptom of your diagnosed insanity, which of course, leads you to even greater desperation. You come to realize the unspoken dictum in society that a psychiatrist’s diagnosis is seldom if ever reversed. In fact there is rarely an opportunity to even get a second opinion. With your institutionalization, you have been deprived of one of the most basic tenets of a democratic society; you have been handed a verdict with little chance of any sort of appeal.

Does this sound like a ludicrous run-of-the-mill plot from a low-budget potboiler? Surely, the scenario that I have painted is a little too far-fetched. Or, is it?

In the early Seventies, David Rosenhan, a professor of psychology at Stanford University in California, devised scientific experiments to answer an eerily similar question: how effective would professionally-trained caregivers be in separating the sane from the insane? In 1973, the results of his experiment were published in a research paper in the prestigious American scientific journal Science.

Let us took a closer look at what Rosenhan found. His experimental setup was elegantly simple. He planned to have eight normal volunteers, including himself, masquerade as psychiatric patients. These so-called fake patients would try to gain admittance to twelve psychiatric hospitals and if admitted, they would immediately revert to behaving what they perceived as “normal” to try to get out.

Rosenhan wanted to perform his experiment thoroughly and put a lot of thought into the design. The psychiatric hospitals were chosen carefully to represent a good geographical mix within the United States. Also, there was a mix of public and public hospitals, and both small and large ones in the experiment. What Rosenhan was striving to achieve was to test if there was any variance to detection of deception in different clinical settings.

In addition, Rosenhan chose his volunteers to represent what society generally considers “serious” individuals. One of the volunteers was a psychology student. Among others were a psychiatrist, a housewife, a painter, a pediatrician, and three psychologists. Five of the volunteers were men and three were women, so there was little gender disparity. None of the volunteers had ever experienced symptoms of any serious mental disorder, so their history gave them a clean chit too.

To keep from the fraud getting detected, volunteers were told to hide names and occupations when they visited the hospitals. An elaborate background story was created for each one of them. Upon arrival at the hospital, each fake patient complained that he or she had heard unfamiliar, muffled voices that uttered the words “empty,” “hollow,” and “thud”. These words were chosen deliberately because Rosenhan felt that they might be construed to existentially signify the meaningless of life, but by no means did they indicate any serious psychiatric disorder. Apart from these falsifications, the volunteers were instructed to provide truthful information to the consulting psychiatrists as long as their anonymity was preserved.

Before approaching the hospitals, the fake patients expressed concern that they would be exposed as frauds. Such anxiety, however, turned out to be completely unfounded. Each and every fake patient presented the same symptoms to psychiatrists in the twelve hospitals tested and not once was the deception detected! Interestingly, the most common diagnosis which occurred eleven times in frequency was schizophrenia. One psychiatrist diagnosed manic-depressive psychosis. Both of these conditions are usually adequate grounds for separating patients from the rest of society.

As part of the plan, once admitted, each fake patient acted as he or she normally would do as far as possible under the circumstances. Each attempted to engage both the patients and the staff in normal conversation as much as allowed. Visitors of these fake patients did not detect any behavioral changes during the stay. Remarkably, despite this observation by external sources, the notion that these fake patients might be sane (or recovering) was never even considered by the hospital staff. The fake patients were in a quandary because normal activities such as writing notes in a diary were judged to be typical symptoms of mental illness. Interestingly, it was common for the other genuine patients of the ward (for lack of a better description) to expose the fake patients as being sane!

If Rosenhan’s experiment presents a bleak picture to you, rest assured that there is a somewhat happy ending. Thankfully, all the volunteers were ultimately released with their “sanity” intact. Hospital administrators had been informed of the experiment prior to the undertaking to prevent the possibility of extended hospitality.

When word of the results of this experiment got out on the street, there was a ruckus. Staff at a very prestigious hospital that had not been part of the original experiment doubted that such serious inaccuracies could happen at their own establishment.

Rosenhan put this claim to the challenge. He told the staff of this hospital that as part of his study, he would send one or more fake patients in the following three months. However, this turned out to be no more than a bluff. No volunteers were sent by Rosenhan in that time-frame. Strikingly, even though no fake patients had been sent to the hospital, the staff examined 193 patients who were admitted for psychiatric treatment during this time and came to the conclusion that that forty-one were not real patients at all!

By this point, you may be wondering how this elaborate experiment concerns the rest of us, since it is unlikely that we will ever be treated for a serious psychiatric disorder. However, all of us will have to visit a physician at some time or other. Statistical studies have indicated that physicians are more likely to diagnose a healthy person as being sick as opposed to find that a sick person is healthy. So much for rational objectivity in the medical sciences!

What can we conclude from this analysis? We can not accuse all physicians of ignorance or malicious intent because that conclusion is a far stretch from the truth. However, we can also safely assume that the results of misdiagnosis are not equal in all cases. Obviously, it is better to treat a healthy person for a disease he or she does not have than to turn away a truly sick person with a clean chit of health. Overmedication or prescribing the wrong medicine is generally not as harmful as failing to detect a real disease. Understandably, physicians almost instinctively err on the side of caution.

The problem is that when a wrong diagnosis is made, it can be difficult to reverse. In the Rosenhan study, after the psychiatrists had diagnosed the fake patients with serious psychiatric disorders, the staff believed that they were patients and all normal activities were perceived as supporting the diagnosis. This tendency is known in psychology as a confirmation bias and it is fairly ubiquitous in our everyday lives.

How does a confirmation bias form? A proposition either preconceived or with mild support finds favor. Then, all information that supports the proposition is magnified in the mind. Any information that can be stretched to support the proposition is also accepted as additional confirmation. Information that directly contradicts the proposition are either ignored or avoided.

The confirmation bias comes to us naturally. Instead of looking dispassionately at evidence, we are programmed to unconsciously sort through data to find patterns that support our theories. Every time the gambler wins a jackpot, it confirms his belief that he is talented. If he loses, it is an unfortunate thought that has to be avoided and put at the back of the mind. Every dream that can be somehow made to fit in with reality is proof that the psychic has supernatural skills; thousands more that cannot be distorted to fit in with reality are either forgotten or explained away.

Even the nature of the information does not matter. The same data is used by the party in power to show that government is succeeding in improving the lives of citizens, and by the opposition to claim that the same citizens are worse of than they were before.

So, should we strive to be completely open-minded in our lives, then? I would argue that such a human does not exist. What I am advocating is that it is possible to train the mind to think critically to try to avoid conformation biases. A simple test is to ask ourselves what evidence we need to reevaluate our currently-held positions. Are we fairly flexible in our views? Do we need an insurmountable burden of evidence to even consider other alternate viewpoints?

All of us like to surround ourselves with those that agree with our views. When our views are uncontested, this allows us to safely stay within our own mental comfort-zones Personally speaking, I often find it difficult to be told that I am wrong and to accept this as a fact. However, to think rationally it is also necessary to be flexible and to consider opposing viewpoints. I know that this is easier said than done. There will always be those that seek to justify religious intolerance, gender bias, caste discrimination, or racism based on what they consider “evidence” that the cohort they belong to is superior to others.

Just take a moment to consider the terrifying power of biased thinking. What would happen if every judge selectively scrutinized evidence to convict an alleged criminal; if every leader rushed into war without heeding warnings from generals; and if every scientist abandoned new ideas that did not conform to rigid theories? That would be an insane world indeed!


The arrow of time

“Daddy, why does time go forward? Why can’t time go backwards?”

I got asked a very simple question by my six-year-old that got the rusty gears, pulleys, and levels cranking in my head.

It’s not an easy question to answer. There is a lot to unpack here.

We take for granted that the arrow of time moves forward because of causality, but the actual physics behind this is a bit more complicated. What if you could actually run time in the reverse direction like playing a tape backward? (Millennials: look up tape; it is real).

Of course, we can observe the past locally and right now- light from stars that exploded billions of years ago is still reaching us now: what we are observing in the past is being experienced in the present. But generally we think of time going forward.

So what’s the answer?

“Time moves forward because, that’s how nature is” or “God made it that way” or “Rules are rules:” But none of these are satisfactory answers to me. So I invoked entropy.

I said “when you break an egg and the yolk spills out, you can’t unbreak it.” It’s a poor way of trying to refer to the second law of thermodynamics. Entropy, which roughly translates to chaos, has been increasing since the universe was created; time moves forward because it is linked and so also unidirectional.

But after the kid went away unsatisfied, my brain went into overdrive. No one actually knows if “time” was created with the universe or if time exists as an entity independent of the universe. Because there’s no way to know. Newton believed that time was absolute and independent of the universe and the universe was simply the stage on which events played out. Clocks were clocks everywhere and counted the same time. This concept has not aged well after Einstein and quantum physics.

As an aside, there’s nothing sacred about our clocks or how we measure time. An hour has 60 minutes because 60 was the favorite number of the ancient Babylonians. They didn’t have fractions and 60 is good for commerce since it can be divided by merchants by 1,2,3,4,5,6… Our clocks move in the direction we call clockwise because they followed from sundials and the people who developed them lived in the Northern Hemisphere. Had civilizations come up in the Southern Hemisphere they’d be invented to run in the opposite direction.

But I digress: back to the concept of time. Einstein changed our views. He made the huge observation that time isn’t absolute or independent and that time and space and linked completely: the curvature in this spacetime is what we call gravity.

Einstein imagined time as another dimension, as another direction like “length” outside of the three that physical objects embody. And this is where it gets weird. Einstein thought we can’t physically observe the time dimension because our brains are three-dimensional.

Einstein also believed that all times coexist– the past, no less than the present or the future. It is only human consciousness and imagination that constructs the physical passage of time. We made this up. So according to Einstein, time does not go forward at all!

And here’s why this works mathematically. If you try to solve the big equations of physics with a negative value of time, they still work. Theoretically, there’s no reason for time to be unidirectional.

For the longest time, a number of physicists thought the universe would expand to a maximum and contract. Time would then play in reverse. Even Hawking wrote the possibility of flipping time after a maximum expansion of the universe. But how? Don’t as me about this one. I find it far-fetched.

Of course, after Einstein came quantum physics which he quarreled with– On the quantum scale, time might not exist as we know it. Most quantum physicists don’t think time is a fundamental property but an emergent one- a secondary result of the universe.

Finally, there are a number of physicists who believe that time does not exist at all. Events are a bunch of “Nows” which we piece together like torn pages of a book or frames of a movie to make a coherent story. Thankfully, this theory is not mainstream, but it is still possible.

A simple iron dagger

After the ancient Egyptian King Tutankhamen died, an iron-blade dagger with a gold sheath was placed in his sarcophagus. This was rediscovered in 1925 after thousands of years.


Nowadays, the gold sheath attracts our attention, but in ancient times, the iron would’ve been much more valuable.

I never thought about this before now.

You might recall the news stories two years ago about this particular iron dagger. There was a scientific article that showed that it was likely of meteoric origin- that it literally fell out of the sky!


Iron is the most abundant element on earth. Why would it be so valuable in ancient times?

And then it dawned on me. The answer, quite simply is that is very little free iron on the earth’s crust. Most of the iron is in ores. Before the iron age, or more accurately before iron smelting was developed, the only way to get iron metal would be from falling meteorites.

The oldest discovered iron, also in Egypt, was of decorative iron beads. And yes, you guessed right- these are also of meteoric origin. They had to be.

For most of humanity iron was this abundant, versatile metal in the ground but no one knew how to extract it or use it!



#MeToo: what should men do?

Friends, I think it is time to address the elephant in the room- #MeToo. Women in India (and elsewhere) are rising in massive numbers to report cases of sexual harassment and assault.

What should men do? How should they react?

To decent men who are wondering what they should do at this moment: speak out against systemic sexual harassment and support the survivors. Just as people who have never experienced racism should speak out against it, men who’ve never been sexually abused should speak out too.

Check your privilege. Listen with humility. There are so many stories.

Introspect. What can you do to make the workplace or neighborhood safer? Racism will not be destroyed only by people of color. The patriarchy will not be dismantled only by women.

I’m learning everyday just how difficult it is for women to come forward in a toxic culture of shaming, victim-blaming, mob threatening and violence, and male impunity. Have an honest conversation with your loved ones. Be respectful: you do not have the right to invalidate anyone else’s experience.

There’s a very basic, low bar for being a decent human being, and men (in the collective) have failed to reach it. If you’ve never sexually harassed or assaulted anyone, congratulations. Here is your prize: you get to start at the very bottom rung on the ladder. And the rest of you? The rest of you, you deserve the lava pit.

Lastly, do not normalize violence as “everything goes”. I do not watch Salman Khan movies. I will not watch Ronaldo in any football match. I will not patronize any comic or journalist who abused or tolerated abuse, regardless of “talent”. If that means I’m sitting at home arranging and rearranging books on my shelf all day, so be it.

Talent or skill is simply the worst excuse: the world will survive and be much better without men who lack humanity.


One of the greatest archaeological discoveries in modern times is the library of Ashurbanipal in the Assyrian city of Nineveh, where there were tens of thousands of tablets with gorgeous Akkadian cuneiform text.

This is an image of a portion of the epic of Gilgamesh from Nineveh, now at the British Museum. I hope to visit the British Museum someday.

Assyrians imported Babylonian culture much in the same way the Romans imported Greek, and Japanese imported Chinese culture. It is said that when Assyrians enslaved Babylonians, they chained their scholars and made them write everything they knew to take their knowledge. All of this was captured on clay tablets.

The entire library of Nineveh burned down, but unlike the destruction of the library of Alexandria centuries later, the books were not completely lost. Because the writing was on clay, each tablet was baked in the fire and became hardened and preserved.

Before I go to the grocery store

What is our place in the universe? To know this, it is important to know who we are and where we came from. Anthropologists believe that modern humans have existed on earth for roughly 300,000 years. If I used my calculator correctly that translates to 0.008% of the time all life has existed on this planet. Indeed, we are not even a blip on the radar of time!

What were our ancestors like? As I mentioned, modern humans evolved 300,000 years ago from an earlier species. We know from bones that at least 150,000 years ago, humans had the same anatomy- the same brain size and capacity for thought that we have today. Did they have history and art and culture like we do? Did they express love and hope and sorrow? We do not know because their lives are lost to us. All of modern human is confined to the last 10,000 years. Written history is even shorter, around half that time. Our collective memory is short.

We know that modern humans came out of Africa 50,000 years ago. Then, there were two catastrophic bottleneck events that nearly wiped us out, and reduced modern human populations to a few thousand people (from whom we are all descendants). That was the closest that our ancestors came to extinction and because they survived we can watch IPL cricket matches today on flat-screen TVs.

But though all of our history is 10,000 years old, a few of our Paleolithic ancestors left us some of our finest art. Let me end on an upbeat note before I go to the grocery store to pick up cashews for pulao that is being cooked today.

This cave painting at Chauvet-Pont d’Arc from 36,000 is one of the OLDEST works of art that humans created that we have found. Isn’t it gorgeous?


(The paintings of these lions at Chauvet-Pont d’Arc are twice as old as the bison paintings at Altamira mentioned in “Agantuk,” which are ~16,000 years old)

Tea time

No one could have predicted in 1690 that in 50 years tea would become the national drink of England. Tea was perhaps the first truly global commodity. The East India Company had a wildly successful marketing campaign to popularize tea in its early years, but all of it came from China. Along with tea, came all the paraphernalia, cups and plates, colloquially still referred to as “china”.

Back then, the well-known tea merchant, Twining’s opened both a coffee-shop and a tea-shop, and was more convinced that coffee would pick up sooner.

It is fascinating how tea, an ancient Chinese drink (that they still drink without sugar or milk) took off in England at the same time that sugarcane became widely available. The English were the first to popularize and widely consume tea with milk and sugar.

A few years later, tea cultivation was introduced in India to break the trade imbalance with China caused by tea importation. Tea in India has never looked back since.
