It is said that laughter is infectious. In 1962, an extreme case of “laughter infection” happened in village in Tanzania. The phenomenon originated in a boarding school for girls. On January 30, three girls spontaneously burst out in laughter and could not stop themselves from laughing. Soon after, the whole class was suffering from fits of uncontrollable laughter. The “infection” then spread throughout the school, claiming 95 of the 159 students over a stretch of two months. This strange symptom of uncontrollable laughter lasted anywhere from a few hours to 16 days. Interestingly, teachers were not affected and only girls between the ages of 12 to 18 were affected. By March 18, the school was forced to close down due to students not being able to focus during class.
The laughter epidemic was not localised to the school. After the school shut down and the girls returned home, fellow villagers were afflicted by the laughing disease, resulting in 217 villagers being “infected” by May (mostly children and teenagers). By June, the laughing epidemic spread to another nearby school, affecting 48 girls. The epidemic then went on to claim two more schools, forcing them to close down. By the time the epidemic died down (6 to 18 months after “patient zero”), it had affected over a 1000 people and shut down 14 schools.
So what was this strange disease? Was it some new viral infection causing neurological symptoms? Was it a toxin in the water supply? The answer was even simpler: mass psychogenic illness, also known as mass hysteria. Mass hysteria is a psychological phenomenon that occurs in groups placed in high-tension situations, such as within an airplane. This setting is perfect for triggering a mass delusion, causing the person to believe they are suffering from a physical disease. The trigger is usually another “patient” and the hysteria spreads like wildfire, usually by people seeing affected victims. Although the above case makes mass hysteria look like a harmless, amusing phenomenon, psychosomatism (when the mind tricks the body into thinking it is sick) can cause symptoms such rashes, fevers, vomiting and even paralysis. In fact, all of these symptoms were also reported during the Tanganyika laughter epidemic.
Parents only have one duty: to bring up their children with love. The problem is that so many parents do not know this fact, or have a twisted understanding of the concept of “love”. Some never even hug their child, some abandon their child for their own lives and some even abuse their child. However, that does not mean one should obsess with their child either. Always teaching the child that “they are the best” is not love. Also, trapping a child and preventing them from leaving you is obsession, not love. Some parents tell their children that studying will lead to a happy, successful future, and compare them to other children who get better grades. This is a crucial mistake, as the children will probably live out an unhappy life with a deep wound in their heart for the rest of their lives. This is because the parents’ role is not to secure a successful future and instructing them how to get there, but to allow the child to independently plan their future, taste failure and develop their own values and philosophy, only supporting them from the side. A parent is not a leader who leads a child along a predestined path of life, but an assistant who supports a child while they pave their own path of life and walk down it. To support and respect a child’s decisions, dreams, talents and potential; to teach the wisdom and skills the child will need to follow their dreams; that is true love.
Of course, that is not to say that one should neglect and leave a child without any interventions. If a child clearly makes an objective error or misbehaves, it is a parent’s role to correct it. This kind of home education is not interference like obsessing about the child’s studies, but supportive intervention that helps the child follow their dreams and not be lost on the way. Home education is a very important form of love that imbues a child with skills such as social skills, ethics, morality, philosophy and love that will allow them to lead a happy and wholesome life.
Why is parental love so important to a child? Childhood is a critical period when the child’s brain is rapidly developing and when the child begins to form his or her personality and view of the world. Almost every mental illness (especially personality disorders) can be traced back to a childhood trauma, or at least be affected by it. For example, a child whose parents did not care for them will grow up lacking love and attachment, leading to constantly seeking love and attention from others, which may develop into dependent personality disorder. If a child has to live up to the parents’ great expectations, they will not receive sympathy and fail to develop a self identity. To fill this void, the child will continuously float from one person to another to seek this sympathy. A child with obsessive parents being led to believe that they are the best could develop narcissistic personality disorder, who becomes violent and enraged when someone points out a mistake they made. As one can see, parental love is a crucial nutrient that fosters a healthy personality in a child, helping them become a wholesome, independent “person”.
No matter how poor the parents are, a child who was raised on love is able to construct a plentiful, happy life. Then, when the child becomes a parent, they will know how to raise their own children with love as well. The best parents are those who respect the child’s decisions and allow them to be free when they set out on their pursuit of happiness. All you need is love.
Have you ever experienced the curious phenomenon where you walk into the kitchen and completely forget why you came there? Or why you stepped out of the house? Almost everyone is struck with this bizarre amnesia at some point in their lives. But why does it happen? Do Men in Black come in and wipe your memory because there was an alien in the room or something? The answer lies in the doors.
It has been scientifically proven that doorways have a magical property of causing memory loss. To be exact, doors do not cause amnesia, but the physical act of passing through a doorway causes the brain to lose memories. The reason for the phenomenon is this. The human brain stores information in a very unique way where it compartmentalises information by physical location. Because of this “filing system”, the thought “I really want cake from the kitchen” that you had in the living room is difficult to access when you are in the kitchen. By crossing a doorway, the brain recognises that the physical location has changed and opens a different “folder”, metaphorically speaking. This system allows for smooth mental functioning usually as it lessens the load on the brain, but also creates confusing situations where you just stand in front of the door, questioning whether you are losing your memory.
In an experiment in France, it was found that when students were told to memorise certain objects and then walk into another room, they had much worse recollection of the objects compared to the control group (students who walked the same distance but not through a door). It was even found that a person did not even have to physically walk through a door to lose their memory. When students were made to repeat the experiment in a virtual setting (i.e. moving a computer character through a door in a game), the same thing happened. The effect was so powerful that the researchers dubbed doorways event erasers.
Although it seems like an inconvenient system, the brain’s special way of compartmentalising information according to physical location can be used to harness the power of complete memory. This is done by using the method of loci, also called the memory palace. This is a mnemonic device first devised by ancient Romans to help memorise a large amount of information. To use the memory palace, you must first visualise a certain location – one that you are familiar enough with to recall with great detail. This may be your room, house, the street you live on, or even a fictional palace. The object of the memory palace is to convert a piece of information into an item which you can place in a certain location in the palace. For example, if you have to memorise a shopping list, you can conjure a mental shelf in your mental palace and put all the items in the shelf. To enhance this effect, make the image as bizarre and fancy as possible, as the mind is prone to remembering weird things more (e.g. a massive apple with eyes and a mouth is more memorable than a normal apple). Once your memory palace is complete, you can take a “mental walk” through the palace, go to the room where the memory you need is stored, and just browse the contents to recall the information. With practice and a vivid imagination, this is an infallible method of remembering anything you want, for as long as you want.
In human society, there are many ways for a person to interact with others when in a group setting. Some may choose to be selfish and only be out for their best interests, while others may choose altruism and cooperate with each other. The mathematical model that tries to predict human behaviour and outcome in these settings is the Prisoner’s Dilemma – the core of game theory. Tit for tat is one strategy that can be employed in such a setting.
The basis of tit for tat is equivalent exchange. A tit for tat player always chooses to cooperate unless provoked. As seen in the Prisoner’s Dilemma, if both players cooperate, both benefit (let us say 3 points each); if one player defects, that person gains more than from cooperation (5 points) while the tit for tat player gains 0 points.
If a tit for tat player is provoked, that player will retaliate. However, the player is also quick to forgive. Ergo, if the other player chose to cooperate, the tit for tat player (following the principle of equivalent exchange), will also cooperate. If the other player defected, the tit for tat player loses the first round and then chooses to defect from then on.
Note that tit for tat strategy only works when there is more than one game so that the player has a chance to retaliate.
Let us use an example to illustrate why tit for tat strategy works. In this scenario, two tit for tat players and two defectors all play six games each, using the above point system (if both defect, they each receive 1 point). The results are as follows:
Tit for tat vs defector: Tit for tat loses first round, both defect for next 5 rounds (5 vs 10)
Tit for tat vs tit for tat: Both cooperate on every round (18 vs 18)
Defector vs defector: Both defect on every round (6 vs 6)
When the points are added up, a tit for tat player gains 28 points (5 + 5 + 18) while a defector only gains 26 points (6 + 10 + 10). This is a surprising turn of events, as the defectors never lost a round and tit for tat players never “won” a round. This goes to show how cooperation leads to better long-term results while selfishness prevails.
There are shortcomings of this strategy. If there is a failure in communication and one tit for tat player mistakes the other’s actions as an “attack”, they will retaliate. The other player then retaliates to this and a vicious cycle is formed. This is the basis of many conflicts ranging from schoolyard fights to wars (although interestingly, tit for tat strategy is also found during wars in the form of “live and let live”). One way to prevent this is tit for tat with forgiveness, where one player randomly cooperates to try break the cycle (a defector would respond negatively while a tit for tat player will accept the cooperation), or the tit for two tats, where the tit for tat player waits a turn before retaliating, giving the opponent a chance to “make up for their mistake”.
Computer simulations have all proven that tit for tat strategy (especially the other two types mentioned just before) are extremely effective in games. In fact, it is considered one of the most optimal strategies in overcoming the Prisoner’s Dilemma.
In human societies, there is usually a mix of “nice people” and “selfish people”. By cooperating and trusting each other, we can produce a much greater gain over time compared to being selfish. And since society still unfortunately has “defectors”, you can retaliate to those who refuse to cooperate by defecting on them also. Ergo, a good approach to life is to initially reach out your hand to whoever you meet and treat them from there on according to how they respond. If they take your hand and want to cooperate, treat them with altruism and help them out. If they swat your hand away and try to use you for their selfish gain, it is fine to shun them and not help them out.
Through cooperation, understanding and connection, we can build a far more productive and efficient society, just like the ants.
On a hot afternoon visiting in Coleman, Texas, the family is comfortably playing dominoes on a porch, until the father-in-law suggests that they take a trip to Abilene (a city 53 miles north of Coleman) for dinner. The wife says, “Sounds like a great idea.” The husband, despite having reservations because the drive is long and hot, thinks that his preferences must be out-of-step with the group and says, “Sounds good to me. I just hope your mother wants to go.” The mother-in-law then says, “Of course I want to go. I haven’t been to Abilene in a long time.”
The drive is hot, dusty, and long. When they arrive at the cafeteria, the food is as bad as the drive. They arrive back home four hours later, exhausted. One of them dishonestly says, “It was a great trip, wasn’t it?” The mother-in-law says that, actually, she would rather have stayed home, but went along since the other three were so enthusiastic. The husband says, “I wasn’t delighted to be doing what we were doing. I only went to satisfy the rest of you.” The wife says, “I just went along to keep you happy. I would have had to be crazy to want to go out in the heat like that.” The father-in-law then says that he only suggested it because he thought the others might be bored.
The group sits back, perplexed that they together decided to take a trip which none of them wanted. They each would have preferred to sit comfortably, but did not admit to it when they still had time to enjoy the afternoon.
This anecdote was written by management expert Jerry B. Harvey to elucidate a paradox found in human nature, where a group of people collectively decide on a course of action that is against the best wishes of any individual in the group. Essentially, the group agrees to do something that would not benefit any one, or the group as a whole. This is the Abilene paradox, colloquially known to us through the idiom: “do not rock the boat”.
As seen in the anecdote, there is a breakdown of communication where each member assumes that the majority of the group will decide to follow the action, pushing them towards conformity. There is a mutual mistaken belief that everyone wants the action when no one does, leading to no one raising objections. This is a type of phenomenon called groupthink (coined by George Orwell in his dystopian novel, Nineteen Eighty-Four), where people do not present alternatives or objections, or even voicing their opinions simply because they believe that will ruin the harmony of the group. They are also under peer-pressure, believing that by being the one voice against the unanimous decision they will become ostracised.
The Abilene paradox explains why poor decisions are made by businesses, especially in committees. Because no one objects to a bad idea (falsely believing that that is what the group wants), even bad ideas are accepted unanimously. This is particularly dangerous when combined with cognitive dissonance, where the group will believe that they chose that decision because it was rational and logical. To prevent this paradox from destroying individual creativity in the group, one should always ask other members if they actually agree with the decision or are merely the victims of groupthink.
Travelling is fun. But strangely, the etymology of the word travel is the Latin word tripalium, which means “torture instrument”. This is most likely because in the old days before airplanes and trains were invented, travelling was often long, arduous and painful. Travelling is probably the least terrifying form of torture. Let us explore the various methods of torture used throughout human history. There are many types of tortures, but they can be largely divided into physical and psychological torture. The main goal of torture is to induce maximum pain to extract information from, punish or to execute a person.
Physical torture is very simple: inflict as much pain as you can. For example, you can simply tie the person to a chair and beat them senselessly, or apply pressure to a wound to cause intense pain. A useful tip for beating someone is to place a phonebook on their stomach or hand and hitting the book, which transfers pains while not leaving a bruise or any marks. A simple way to cause extreme pain is the use of fingers. Finger tips are extremely sensitive and contain many nerve endings, meaning sticking needles under the nail bed or ripping the fingernails off causes extreme pain. Like this, medical knowledge has often been used to develop new ways to torture people. For instance, heating the sole of the feet with fire causes severe pain, electricity used in the right amount can keep the person alive while causing pain and seizures, and if you lie a person flat and on a slight decline (so the head is lower than the body), put a cloth over their face and pour over it, you can induce a sensation of drowning (this is called waterboarding and is used by the CIA). Another simple, effective torture method is the joori-teulgi(주리 틀기) from Korea, where a person is tied to a chair with the feet bound, with two long sticks inserted between the thighs, crossed, then pulled down to streth the thighs apart. This causes extreme pain and suffering.
As mentioned above, torture can be used to kill a person too. The famous hanged, drawn and quartered torture was used in the Middle Ages to punish treasonists. The convict was drawn behind a horse for a while and then hanged until just before death, when they were disembowelled, beheaded and quartered. Another strange, complicated method of torture can be found in China, where slow slicing was used. Slow slicing involves tying a convict to a post and cutting slices of flesh off him until he dies. Executioners often had an art of slicing in such a way to prolong the suffering for as long as possible without killing the person. Another execution method found in both Western and Eastern history is dismemberment by horses, where the person’s four limbs and head are tied to individual horses (or cows), which are then made to run in different directions to violently rip the person up.
Animals were used in various forms of torture throughout history around the world. Tying the prisoner to an elephant’s feet to crush them to death, putting a rat on the person’s stomach then putting a pot over it and heating it with fire to make the rat burrow into the person’s guts, feeding them to lions or vicious dogs, coating them in honey and leaving them in the path of fire ants to make them get slowly eaten… Out of all of these, the most bizarre method is the goat torture used in ancient Rome. This torture involved tying the prisoner to a chair and securing their feet, which were coated with salt water. Next, goats were released around the prisoner. The goats would lick the sole of the feet to cause tickling, which over a prolonged period is interpreted as pain by the body. This eventually drives the person insane from pain.
Unlike physical torture, psychological torture induces shame and fear rather than pain. Threatening, solitary confinement, sleep deprivation, rape and sexual torture, sensory deprivation, exploitation of phobias, loud noises (such as banging on a door constantly), blindfolding the person and rubbing a balloon on their cheeks, placing foreign objects or snakes in the anus or vagina, leaving them in a container full of insects… Psychological torture has just as much a variety as physical torture and can have longer lasting effects on the person. Furthermore, as it leaves no external marks, it is still frequently used in the modern day.
No matter what the method, inducing extreme pain to control people, extract information and cause suffering is an inhumane act that cannot be tolerated. If mankind had focussed their creativity and effort into more constructive and altruistic things rather than discovering various ways to cause pain, we would probably be living in a much better world.
The following is an incidental finding from an experiment studying conditioning in dogs. In stage 1, a dog was tied on a leash in a room with electrified floors to prevent it from running away and was shocked for a day. Next, the dog from stage 1 and another dog were left in the same room without any leashes, leaving the door opened so that they could run away when they were shocked. Although the dog that did not pass stage 1 (fresh dog) immediately ran to the next room, the dog from stage 1 just helplessly lay down on the floor, receiving the electric shock. In stage 3, the same dog from stage 1 was taught that going to the next room prevents it from getting shocked. However, even after learning this, the dog refused to move and stayed in the room and accepted the shock. It had learned helplessness.
Everyone has depressing moments in their lives, but when these repeat over time it can cause you to feel that life is an inescapable pit of despair. You will learn a sense of helplessness that no matter what you do, the result will be failure and disappointment. But the moment you accept this helplessness, the nightmarish fate that you loathe so much becomes reality. There is no such thing as fate or destiny. If you do not like the fate given to you, free yourself the restraints of life, break away from the fetters and pioneer a new future for yourself.
We laugh when we are happy. Laughter provides us with happiness and is the best medicine available to us, relieving the pain and stress of life. In fact, when we laugh we secrete a neurotransmitter called endorphin, which as the name suggests (endo(inside) + morphine), has the same properties as morphine.
What makes us laugh? The best theory to date is that laughter is an instinctive response to the passing of danger (also called the relief theory). For example, if our ancestor came across a predator but it passed by without noticing him, he would have laughed in response to the relief he felt. Others would see from his laugh that the danger had passed and laugh also (possibly explaining why laughter is contagious).
This theory also explains why humour makes us laugh. When you throw a joke, you are essentially giving the other person a “cognitive riddle” with a logical inconsistency. This inconsistency causes the recipient’s subconscious to become confused: “Why is it funny? Why can’t I understand it?”. As jokes are fundamentally a “surprise” to the other person’s mind, they try to solve it and figure it out whether it is a danger or not. If they get the joke, the inconsistency is solved and the person feels relief (as it has been revealed that the confusion brought on by the inconsistency was not dangerous). Once the confusion passes, the person laughs in response. But if the person does not get the joke, the “danger” has not passed and the person does not laugh. This is the basis of one of the laws of comedians: “if the audience is confused, they do not laugh”.
Laughter is beneficial for your health. Frequent laughter lowers the blood pressure, boosts the immune system, relieves pain and lowers the levels of stress hormones such as cortisol. Laughter is especially good for your mental health, therefore having a five-minute laughter yoga session every day where you just laugh as hard as you can will help you lead a happier life. However, ironically laughter can kill you too. Cases of “death from laughter” have been recorded since ancient Greek times to the modern day. The cause has not been identified but it is known that intense laughter can cause cataplexy, which is a paralysis induced by extreme emotions. It is possible that intense laughter overloads the nervous system and causes a heart attack.
A “good fortune teller” is not an “accurate” fortune teller. A “good fortune teller” is a fortune teller who “says good things”. A fortune teller who tells fortunes that are too real, despite warning people of the dangers to come in the future, tends to be ignored and hated on just like Cassandrafrom ancient Greek mythology. Human beings say they fear uncertainty in the future and want some certainty, but they do not want to hear about an unhappy future. This is a normal response. Who would want to hear that they will soon be diagnosed with a terminal illness, or that they will break up with their lover? However, people are fascinating in that they still try to know the future. We go to fortune tellers and read horoscopes to try figure out what will happen to us. But if they receive bad news such as “you will fail your next exam”, instead of studying even more they curse at the fortune teller for giving them a bad prediction. Thus, human beings live among curiosity about their life and fear of the unknown future, while celebrating good fortunes and actively denying bad ones.
The reason why we like to have our fortunes read is similar to why we watch previews of television shows: we are curious about what will happen. But if you ponder this deeply, you soon come to a great epiphany. The further you look out into the future, the clearer this becomes. Everyone eventually dies. A person’s life span is typically not much longer than a hundred years, with everyone meeting the same fate some day.
A fortune teller predicts the ups and downs of a person’s life. If you think about it, life is composed of a series of peaks and troughs that eventually result in death. No matter what misfortune comes your way, it will pass just as seasons come and go. A person who passed an exam is happy and leads a good life, but even if the person fails, they somehow make it through. Unless you give up, a person will continue to live on. C’est la vie. Life is as simple as that.
If the best fortune teller in the history of mankind told your fortune, they would say the following: “nothing matters, live the way you want”. Whether your fortune for the week is good or bad, you will eventually die. There is no point scaring yourself with fortunes, live every day as if it was your last. An uncertain future may be scary, but it also represents infinite possibilities. Just like Schrödinger’s cat, our tomorrows are both alive and dead at the same time. Until tomorrow comes and the box is open, we can never know what the future holds.
So as long as it does not harm you or anyone else, do whatever the hell you want.
This world endlessly tells us to live for the desires and wants of others. We live every day to fulfil the desire of our parents, our teachers, our friends and our lovers. But to live for other people’s desired, you must first fulfil your own desires. For our weak “self” identity to survive and develop, we cannot allow other people’s desires dominate us.
There is a mental illness called delusional disorder where the patient is obsessed about a “false belief” and is completely convinced that it is the truth. The word “delusion” brings to mind strange cases such as “I was abducted by aliens” and “the government is monitoring my phone calls”, but these delusions are more common with conditions such as schizophrenia. Instead, delusional disorder presents with delusions such as Othello syndrome (believing your spouse is having an affair) or hypochondria that are not too strange and allows for a relatively normal day-to-day life, making delusional disorder very hard to detect. Furthermore, the patients form these delusions in a very logical and highly structured manner, causing the patient to become easily obsessed with it and make the delusions more believable.
Delusional disorder can be categorised into six types:
Erotomanic type: delusion that someone is in love with you
Grandiose type: delusion that you are godlike and possess greater value, strength, intelligence or identity than others
Jealous type: delusion that your lover is unfaithful
Persecutory type: delusion that someone is acting malevolently or trying to harm you
Somatic type: delusion that you have a medical condition or physical defect
Mixed type: delusion showing characteristics of more than one of the above types, with no one type being prominent
As these patients are so attached to their delusions, treatment is extremely difficult. As soon as a psychiatrist or psychologist attempts treatment or even a close friend denies the delusion, they instantly become an “enemy”. The patient automatically incorporates those people into their delusion and antagonise them to worsen the situation. This is why the key principle of treating delusion is “do not touch the delusion”. For example, if the patient believes they are someone else, instead of negating that delusion you should give them a chance to be that person. A treatment called “psychodrama” uses impromptu acting to bypass the delusion and tries to reach the patient’s subconscious, or their “self”. Through this, one can approach the patient’s “self” via affirming their delusions, allowing the psychiatrist or psychologist to ask what the patient’s “self” wants and discover the source of the delusion. The important point is that this treatment is not an instant cure for the delusions (it takes a while for the patient to rid themselves of the delusions completely).
Delusional disorder is a phenomenon which is not uncommon in people who live for the desires of others. A perfect example would be young celebrities. If young teenagers begin life in the entertainment sector and live for the audience before they develop their own “self”, they may not be able to find answers to questions such as “who am I” and “what do I want”, ultimately causing a weakening of their identity. As the “self” is highly capable of tricking itself, it creates a delusion that can rationalise this situation and works to create a different identity.
Thus, the most important tool for surviving in this world is not money, power, wisdom or love: it is your identity and “self”. If you do not know what you truly want, then life cannot give you happiness and success.
