Conformity

We often see people who criticise others for being “sheeple” – people who blindly conform to the majority and follow someone like sheep do. They protest that as human beings, we have a right and duty to exercise free will, sticking up for one’s own opinions. However, according to an infamous experiment from the 1950’s, we know that human beings are bound by our natural instincts to be social creatures, obeying the collective will of the group we are in.

In 1953, Solomon Asch designed an experiment to study the power of conformity. He told participants that they will be taking part in a vision test with a group of people. They were shown a picture depicting lines of various lengths, asking which line on the right matched the line on the left:

It was a simple task of matching the line to another line of the same length with the answer being blatantly obvious. But as with so many psychological experiments, there was a trick. The group of “participants” were actually in on the experiment other than the one subject. During the experiment, the group would all put their hands up on the blatantly wrong answer instead of the actual correct one. How did this action affect the subject’s answer?

Although it seems clear that the answer is A in the given example, when in a situation where the majority of people put their hands up for “B” or “C”, up to 32% of the subjects gave the incorrect answer. No matter how large the differences were between the sizes of the lines, the results did not change. Although 32% is only a third of the study group, one must bear in mind that this experiment only looked at black-and-white scenarios of lines of different length. If the issue at hand was much more “grey” – such as an ethical dilemma – it can be extrapolated that the person would easily sway and conform to the majority opinion.

The reason for the level of conformity exhibited in the experiment is quite simple: it’s the one who is different that gets left out in the cold.

Six Degrees Of Separation

It is said that through a chain of five people, we can be acquainted to anyone in the world. In other words, an Eskimo man can be no less than six steps away from a Parisian lady. This is the concept of the six degrees of separation.

The concept can be explained mathematically. We all know hundreds of different people each. If we assume that we each have 100 friends, then in the first stage we only know the 100 friends. However, at the second stage we know the 100 friends of each of our friends, meaning we know 10000 people. At the third stage we know 1 million people, fourth stage 100 million and fifth stage 10 billion people. As the world population is 7 billion, by the fifth stage we should theoretically know every person on the world. This means that crossing four metaphorical bridges lets us shake the hands of anyone we want. The concept of the degrees of separation came from the idea of the small world phenomenon.

The first person to properly study the small world phenomenon was Harvard social psychologist Stanley Milgram. In 1967, Milgram asked 296 people in the Midwest (USA) to help him send a package to someone in Boston. To complete the experiment, the participants had to send the package to one of their friends they thought would know this stranger in Boston. Milgram found that in half of the cases, the package was delivered to the target in Boston through five people (5.5 exactly), thus giving birth to the concept that we are at six degrees of separation from another human being. 

Of course since 1967 our societies have undergone many changes. One of the most noticeable changes has been the development of technology – specifically the development of the internet and social networking. Nowadays, the younger generations use the internet to communicate with friends and make connections. Knowing this, what degrees of separation exists in modern societies? According to a recently finished study (2011) using data from the social networking site, Facebook, the average number of “bridges” for the world is 4.7. In countries such as the US where there is a bigger proportion of Facebook users, this number fell to 4.4. Ergo, in the past 40 years we have developed more connections to other people, making our world even smaller.

The theory of six degrees of separation reminds us how small a world we live in and how interconnected we are to each other.

Emotion

Unless you are a psychopath, as a human being you are bound to feel emotions. Love, happiness, anger, sadness… there are many emotions that range from simple to complex. Emotions are an interesting system as they allow us to respond rapidly to a situation without thinking, while alerting other members of our society to what is happening to us. Essentially, emotions help us in survival and social interactions. 

According to Professor Paul Ekman, emotions are universal from culture to culture, with facial expressions being almost identical from tribal cultures to modern ones. He found that there are six major emotions: anger, fear, disgust, sadness, surprise and happiness. He also pioneered the field of micro-expressions, which studies the flickering change in our facial expressions whenever we feel a certain emotion. As emotions usually occur before the conscious mind thinks, we are often unaware of the expressions we make.

Another psychologist, Dr. Paul Gilbert, divided emotions into three affect systems. They are as follows:

  • Threat/protection system: associated with the fight-or-flight response, activates in response to danger. It causes anger and fear and is related to catecholamines (e.g. adrenaline) and cortisol (stress hormone).
  • Want/desire system: associated with hunting and rewarding behaviour, helps us perform actions that aids survival such as obtaining food and mates. It is related to the emotion of excitement, which is caused by the neurotransmitter dopamine (part of the reward system).
  • Contentment system: associated with met needs and social connection, especially when we feel safe and relaxed. It produces feelings of happiness and peace, linked to the hormone oxytocin (released with human touch, especially during kissing).

Dr. Gilbert also posited that as societies have evolved over time, our affect systems have been altered. For example, despite the lack of natural predators around, urban dwellers are often in a state of high anxiety. This causes a sustained stress response, leading to negative health outcomes. Furthermore, the agitation and the paranoia caused by constant fear leads to crimes such as murder and war. Our want/desire system has also been heightened as we find pleasure in gaining material wealth. This has led to aggressive capitalism, exploiting other people and the environment for selfish gain.

On the other hand, the contentment system has shrunk. People feel less content despite being in a generally healthier and richer world than 100 years ago. The reason being, our brain has evolved to help us survive, not to keep us happy. 

One must learn how to adapt to these changes by finding a way to relieve tension and stress, while finding inner peace and happiness. Whether it be through sports, music, humour or simply talking to another person, finding your own way to deal with anxiety is the best road to being happy and content.

Symptom Reporting

Some people always complain of symptoms, claiming that they are sick, while some people never seem to complain even if they have a whole list of symptoms. Why is there a difference in symptom reporting between people? For example, women are more likely to recognise symptoms and report them compared to men. This is because men are generally under the social pressure of needing to appear strong and healthy, so they become stoic and less sensitive to pain and disease. Women are usually more sensitive to internal bodily changes and worry more about their health.

According to a psychological theory called the competition for cues hypothesis, there are two signals that compete for attention when we recognise symptoms. The first is bodily changes, i.e. internal cues, while the other is external stimuli from what happens around us. Awareness of symptoms follows a ratio between these two signals: if there is a strong internal cue such as severe pain, we notice symptoms more quickly, while if there are many distractions, we may not notice the symptom. For example, according to a study people can run faster when listening to music and running through a forest with plenty to see. This is because music and the scenery distract the runner from internal cues. As we can only process a certain amount of information at a given moment, the more distractions there are the less sensitive we become to signals from inside our body.

Another factor that affects symptom reporting is illness labelling. The more information we have about a disease, the more we search for those symptoms. For example, if you yawn or scratch yourself, people around you will do the same. This is because they see you yawning and subconsciously believe that they should yawn too. This can be a powerful effect, as seen in mass hysteria. This strange phenomenon occurs when a person observes a sick person and their brain believes they are sick too, beginning to show symptoms despite being healthy. A similar example is seen in medical student disease, where medical students, with their extensive knowledge of diseases, match their own symptoms to symptom lists of rare diseases. For example, they might think that their high blood pressure is due to a phaeochromocytoma or renal artery stenosis, rather than just hypertension.

However, the opposite can occur where people fail to notice important symptoms and suffer serious consequences as a result. For instance, not all cases of heart attacks (myocardial infarction) cause unconsciousness and a patient may believe they are fine when only chest pain occurs. Failure to get treated as soon as possible at a hospital may result in ventricular fibrillation, leading to sudden death.

Hypocrisy

Often in life, we find that other people can be idiots, evil or both. Whether it be the girl working in the cafe that forgot your order, or your girlfriend who says she was late because of traffic, or the bastard that takes the last slice of pizza. But then, when we do that exact same thing that annoyed us so much when someone else did it, we somehow always find an excuse that rationalises our act.

This can be explained by the phenomenon of special pleading. Instead of acknowledging the fact that what you did was incredibly rude or obnoxious, your brain automatically creates an exception to the rule. You forgot that customer’s order because you were having a bad day. You were actually late because of traffic. You took that last slice of pizza because you did not have as much as the others and everyone else looked full. This phenomenon rids us of feeling guilt after an “immoral” act and also enables our hypocrisy.

The best part is that we do not consciously know of our hypocrisy. The brain quickly devises a clever reason to explain why you are the exception to the rule, while everyone else is not. The reason is, as with so many other psychological phenomena, cognitive dissonance. The brain cannot comprehend that you would do something you find so detestable when someone else does it, so it forces itself to believe the reason it pulled out of the air to not feel guilty, as it is the only reason the brain can think of that explains your behaviour. Furthermore, as sometimes the excuses are true, our hypocrisy is reinforced and we continuously disobey the golden rule of “Do unto others as you would have them do unto you”.

Perhaps the more realistic, platinum rule should be: “Do unto others as you would have them do unto you…UNLESS”. It may not be a good moral system, but it sure explains the human condition of being an ass.

Hypnagogia

Every person has had the experience of having a few seconds of brilliance just before their consciousness slips into sleep. During this short moment, we have some of the most creative and innovative ideas. Unfortunately, this is all lost by the time we wake up. This state is known as the hypnagogic state and has been well known since ancient Greece. Many philosophers and writers such as Aristotle and Edgar Allan Poe have written on the subject and how they received some of their greatest ideas in this state. 

Recent researches show that during hypnagogia, thought processes and cognition vastly differs to normal wakefulness. It appears that hypnagogic cognition is more based on the subconscious mind, with people in this state being more open to suggestion (e.g. hypnosis). Ideas seem to flow in a fluid yet illogical way and they are based on external stimuli, thus explaining the heightened suggestibility as the brain incorporates the surrounding into its thought process. The thought process is also less restricted, leading to openness and sensitivity. A process called autosymbolism occurs where abstract ideas that we are thinking are converted into concrete images. This explains the artistic inspiration seen in hypnagogia.

One of the more pronounced phenomena of hypnagogia is insight. It has been noted by many people throughout history that the moment before sleep is when we have the best ideas. For example, a chemist called August Kekulé realised that benzene was a ring structure after seeing an image of snakes biting each other’s tails to form a ring. Because of this, many famous artists and inventors tried to harness the power of hypnagogia through techniques such as the Dalí nap. Thomas Edison, Isaac Newton, Beethoven and Richard Wagner also practised similar techniques to gain insight into a problem that they were trying to solve or bring fresh ideas.

Another fascinating side of hypnagogia is the strange sensory phenomena associated with it. As in the case of sleep paralysis (which usually occurs in hypnapomp – the state between sleep and waking up), people often report strong hallucinations in the form of bright colours, geometric shapes, or even nightmarish visions (such as a ghost sitting on your chest). Other senses are affected as well, such as hearing whispering (commonly associated with the nightmarish hallucinations mentioned above) or out-of-body experiences. Hypnic jerks are also common, where the person jerks awake just before drifting off to sleep. This is thought to be caused by the brain misinterpreting sleep as “death” or the body shutting down, leading it to jolt the system back to life. 

Finally, an interesting psychological phenomenon is the Tetris effect, where people who have spent a prolonged time on one activity cannot stop seeing images and thinking about that activity in the hypnagogic state. This was seen in people who had played too much Tetris seeing coloured bricks before they went to sleep. Other common versions of the Tetris effect include chess boards and pieces, feeling waves after being at sea and seeing words and numbers after working on documents for a long time.

The combination of insight, creativity and sensory illusions leads to hypnagogia causing strange “experiences”. Ergo, hypnagogia is now thought to explain many supernatural experiences such as ghost sightings, UFO abductions, premonitions and visions.

Hedgehog’s Dilemma

Imagine two hedgehogs in the middle of winter. Even though they wish to huddle together to keep warm, they must keep distance to not become stabbed by the other hedgehog. There is no way they can avoid hurting each other without keeping their distance. Although both hedgehogs badly want to be close and intimate, they cannot. Therefore, the hedgehogs sacrifice the potential warmth for their own comfort.

Human relationships are just like the hedgehogs in the allegory. If a relationship is too close, the two people have a serious danger of hurting each other in one way or another. It is crucial to find the balance between keeping distance and having enough intimacy to have a good relationship, but much like the hedgehogs, this is a very difficult task. 

Some people may have the unfortunate experience of being pricked by another hedgehog and learn that getting too close hurts too much. These people try and keep their distance from other people and rely on their internal warmth to not freeze during the winter. This phenomenon is more pronounced in introverted people and clearly seen in those suffering from social anxiety.

This is the dilemma of the hedgehogs: should one sacrifice the warmth of companionship to avoid pain? Or should one overcome the potential pain to attain the intimacy that we all seek? Figuring out where the perfect balance lies and respecting each other’s personal space is quite possibly one of the most important factors in having a healthy relationship.

Nirvana Fallacy

Humans have a tendency to think in a black-and-white manner, leading us to fall into the trap of the Nirvana fallacy. This is when one compares the real world to some perfect yet unrealistic alternative, causing reality to pale in comparison. Thus, it causes us to believe that many things are not worth doing as they are insignificant compared to this alternative.

For instance, the notion of the drop in the ocean means that we tend not to do altruistic things as we believe that it will not make much of a difference in fixing poverty or cure the world of cancer. Not only does the fallacy apply to how we see the world, but it affects day-to-day life too. People are so afraid of not being able to achieve an ideal, perfect future so ironically they do nothing. This is a major reason procrastination happens, as the person believes that if they do something now, it will be inefficient. They then plan for a perfect opportunity to start doing work, and a vicious cycle begins. Thanks to this way of thinking, people often miss out on a great job opportunity or a lovely girl or a chance to change their life just because it was not perfect and did not live up to their expectations.

In fact, people often fail to see the small steps and only see the big picture. So if someone tries to make an improvement (e.g. going on a diet), others will ridicule that person by saying that going to the gym every week is not going to turn you into an Adonis, ergo it is pointless.

The Nirvana fallacy is also useful in debates. One can create a false dichotomy (that is, a black-and-white argument) and compare someone’s argument to an unrealistic argument. When someone makes a suggestion, you can attack it by pointing out one flaw and show how it is clearly not a perfect solution (even better if you provide an example of the argument failing). This will automatically disintegrate their argument. For example, if someone proposes a new idea, you may point out how someone may abuse the new system or provide a case when a similar idea failed. However, be warned that this method can easily be rebutted with common sense, so one must use it in a convincing way and distract the audience from the fact that it is absolutely ridiculous.

Munchausen’s Syndrome

Some people are known to overreact regarding their health, such as a hypochondriac thinking that she has kidney failure because her urine looks slightly frothier. However, some people far surpass the level of hypochondrias to the level of psychiatric disease.
Münchausen’s syndrome patients are known to exaggerate or create symptoms so that the doctor would pay attention to them. When the doctor investigates, treats and sympathises with the patient they gain satisfaction from all the attention they are receiving.
Although this may sound like hypochondrias, Münchausen’s is far more serious.

A Münchausen’s patients are known to cause symptoms just to get attention from others. For example, a common manoeuvre used is the injection of insulin to induce a hypoglycaemic seizure. When their symptoms are “treated”, the patient will most likely invent another factitious disease to be treated for a longer time. They will also seek out many different doctors when the attending doctor catches on to their act. In fact, a Münchausen’s patient will do almost anything to prolong medical care, even accepting unnecessary and risky procedures such as surgeries.

The key difference between Münchausen’s syndrome and hypochondriasis is that the patient is aware that they are not actually sick (hypochondriacs actually believe they are sick). The fundamental basis for Münchausen’s syndrome is the desire for attention. Thus, the main risk factor for developing Münchausen’s is childhood experience of seeing someone close (typically a family member) suffering a debilitating disease. For example, if a girl sees her sister suffering from leukaemia and receiving all the attention of everyone around her, she may develop feelings of jealousy and later try to duplicate the scenario. As a patient, the person feels safe and comfortable and this feeds their addiction to medical care.

As Münchausen’s patients are very proficient liars and act completely like an actual patient, doctors must rule out any diseases before suspecting that their patients have a psychiatric problem. However, some signs such as the patient being overly keen on receiving procedures such as biopsies or continuously developing random symptoms may indicate Münchausen’s.

Interestingly, a similar condition called Münchausen’s syndrome by proxy also exists, where a caregiver (e.g. mother) convinces a doctor that the person they are caring for (e.g. child) are sick. Unfortunately, as these patients actually cause illness in the child, it is considered a form of child abuse. Common “symptoms” include: growth problems, asthma, allergies, vomiting, diarrhoea, seizures and infections. This may lead to the child developing Münchausen’s syndrome in the future.
