Power Of Thought

The power of thought is extremely potent. Beliefs can drive people to extreme actions, or let those who lost everything pick up and carry on. Not only does this apply to religion, but all beliefs have a powerful effect on us.

The most easily observed effect is that the mind has over the body. In the 1950s, an accident occurred where a sailor was trapped in a refrigerated container on a cargo ship. There was plenty of food, but he knew he had no hope when his fingers and toes begun to go numb, and as his body started go stiff. Instead, he decided to record the pain and suffering of freezing to death on the wall using a piece of metal. By the time the ship arrived at the port, he had already frozen to death. However, the container was not refrigerated as it was not being used – the sailor had killed himself with the power of thought.
This shows how thought affects the way we perceive the world, which forms the basis of the placebo effect. If you give a patient sugar pills and tell them it is medicine, it is common to see an improvement in their health. This is due to the body’s amazing ability to repair itself, yet the brain believes the drugs helped it recover.

Thoughts and beliefs affect society as well.
Private property, the monetary system, authority and ethics are all products of the human mind. This is called the Tinkerbell Effect, where some things only exist because people believe in them. The name comes from how Tinkerbell from the play Peter Pan is revived with the belief of children.

Furthermore, believing can determine the future. In philosophy, there is something called the Thomas Theorem, which states that “If men define situations as real, they are real in their consequences”. For example, if there is a rumour that a bank will go bankrupt, people will withdraw their money and cause the bank to go bankrupt. 
This theorem explains self-fulfilled prophecies, a type of prediction that causes the events to take place because of the prophecies. Horoscopes and fortune telling are largely based around this effect, where telling a person that “good things will happen” (or bad) will cause the person to think positive (or negatively) and result in them acting in favour of positive results (or negative). 
This strange phenomenon is described very well in the movie “The Matrix”. When Neo visits the Oracle, she tells him “Don’t worry about the vase”. When he says “What vase” and turns around, he knocks over the vase behind him, causing it to fall and shatter. The Oracle then questions whether the vase would have broken if she had not told him about it. A similar case is seen in “Terminator” and “Back To The Future”.

As shown above, thoughts and beliefs contain immense power, and all humans need to do to make a better world is imagine and believe in such a world. However, the problem is that we seem to be unable to utilise this potential.

Doppelganger

A doppelgänger is popularly known as a “double” of oneself, with the exact same appearance but usually with a completely different personality. 
It comes from German folklore (the word is German for “double walker”), where it is believed that seeing a doppelgänger is an omen of bad luck, possibly death. It is also said that meeting one’s own doppelgänger will result in one of the two dying. 
However, in modern times this concept of doppelgängers have been largely replaced by the first meaning, that of an alter ego who is only identical physically, and completely different persona-wise. This can sometimes overlap with the concept of an “evil twin”, as a doppelgänger is sometimes described to have an inverse personality, values and motives.

Although in most cases a doppelgänger is just a look-alike, it could be the result of the brain projecting an identical image of oneself in another space. 
It has been discovered that electrical stimulation of an area of the brain called the left temporoparietal junction causes the sensation that someone is next to you. This “someone” has the same shape and body posture as the subject, and is sometimes described as having a completely different personality. It is reported that this sensation is extremely unpleasant.
The cause of this phenomenon is that the area of the brain is associated with self-image, such as body posture, location and proprioception (sense of what oneself appears as in space). Therefore, a disruption leads to the self-image being projected elsewhere, which the brain then interprets as a doppelgänger.

There are similar mental disorders such as the Capgras delusion (belief that someone close has been replaced by a doppelgänger), Fregoli delusion (belief that many people are the same person in disguise) and subjective doubles (belief that one’s own doppelgänger is acting on its own to interfere with one’s life).

Doppelgängers are common plot devices in many works, especially fantasy and science fiction where the aforementioned “evil twin” concept is used. However, the doppelgänger may also be described as benevolent or simply a clone.
They are notably used in How I Met Your Mother, where each character has a doppelgänger completely different to their persona (e.g. Stripper Lily, Fertility Expert Barney).

Love And Heartbeats

A thumping heart is often quoted as the first sign of love – a way of your body telling you that the girl or boy in front of you is what you desire.
But does love come first or does your heartbeat come first?

Although most people believe that their heart is beating faster because they’re in love, science proves that it is in fact the opposite.
An experiment was designed where male subjects were asked to answer a questionnaire given out by an attractive woman. One group had to cross a very long suspension bridge first, the control group had to cross the same distance on flat, solid ground. It was found that men from the first group were more likely to complete the questionnaire, give answers that were more romantic and sexual, and even call the survey girl afterwards.

Similarly, a group of men were shown four women while being connected to headphones that played back their own heart sounds. They were then asked to rate which girl was the most attractive.
After the experiment, it was found that the third girl received a landslide win, despite the different tastes of each man in the group. When asked, the subjects all replied that they heard their heart speeding up, thus believed that they found her the most attractive.
The twist was, when the third girl was shown, the audio was changed from the subject’s heartbeat to a pre-recorded heartbeat that beat faster than normal. Therefore, the men were fooled into thinking that the girl was more attractive by “increasing” their heart rate. This phenomenon was found in women also.

The answer to the question is that dopamine and serotonin, neurotransmitters secreted when a person is in love, also has the effect of increasing one’s heart rate. The brain therefore can misinterpret an increased heart rate as the effect of love through false association.
This effect is quite well known in dating tips as people are encouraged to go to places that invoke fear or excitement, such as an amusement park, horror movie, or high place to gain the best response from the opposite sex.
Ergo, science does play a role in love and just like anything else, it can be easily manipulated.

Forer Effect

Read the following passage, and rate out of 5 how accurately it describes you:

You have a great need for other people to like and admire you. You have a tendency to be critical of yourself. You have a great deal of unused capacity which you have not turned to your advantage. While you have some personality weaknesses, you are generally able to compensate for them. Disciplined and self-controlled outside, you tend to be worrisome and insecure inside. At times you have serious doubts as to whether you have made the right decision or done the right thing. You prefer a certain amount of change and variety and become dissatisfied when hemmed in by restrictions and limitations. You pride yourself as an independent thinker and do not accept others’ statements without satisfactory proof. You have found it unwise to be too frank in revealing yourself to others. At times you are extroverted, affable, sociable, while at other times you are introverted, wary, reserved. Some of your aspirations tend to be pretty unrealistic. Security is one of your major goals in life.

Does it fit your personality quite closely? Interestingly, in a study of 150 university students, the average score given was 4.26 out of 5. This is actually composed of pieces of horoscopes by the psychologist Bertram R. Forer, who studied the psychology of horoscopes. As one could see (on retrospect), the above paragraph involves many sentences that would fit almost everyone.

It is through these broad yet somehow specific-sounding statements and the human psychology that the words describe exactly who they are that allow horoscopes and fortune tellers to gain such a profit.

Morality

People tend to believe that morality is an absolute concept, or that people cannot easily be “turned” away from their values. However, many interesting experiments have proved that our morality may be more easily manipulated than previously thought.

It has been shown that various factors affect our decision making processes. For example, when a subject is near a drawing of an eye, such as a poster, they tend to be more honest and less likely to cheat in an exam. The opposite effect is seen when there is dim lighting, even if it is only slightly dimmer (as in not dark). This can be explained by our subconscious wanting to be moral when seen by others, while acting much more freely when it believes we are hidden (the classic example being babies believing that if they do not see it, it does not exist). Not only are there obvious examples like this, but there are also strange factors such as large trees lowering crime rates, while examples of bad behaviour (such as graffiti or broken windows) elicit bad behaviour on the observer as well. 

The relationship between religion and morality has also been a time-old philosophical question. It has been shown that anything that invokes the image of a deity brings out generous, good behaviour in people, as it plays to the fear element (that someone is always watching and will bring consequences) in the mind. However, there have also been cases such as a police strike in a Canadian town causing mass lootings and a significant spike in crime rates despite the strong religious background of all the people. It is also notable that Hitler and Stalin were both strong Christians, yet their actions are still considered some of the most evil acts in history.

Therefore, it is entirely possible that morality is a learned behaviour that only exists for an effective society, meaning that it can also be twisted by many different factors.

Ganzfeld Effect

To experience this peculiar effect, you require a ping-pong ball cut in half, tape, radio, headphones and a lamp tinted with red light (use cellophane).

  1. Set the radio to an empty station so that only white noise is playing.
  2. Plug the headphones into the radio and wear it.
  3. Place each half of the ping-pong ball over your eyes and secure it with tape.
  4. Shine the red light towards your eyes.
  5. Relax on a couch or a bed for over half an hour.

What you will experience after about half an hour are powerful visual and auditory hallucinations, the result of your brain trying to fill the void created by sensory deprivation. As the brain is in constant need of stimuli, complete deprivation of the senses results in the brain becoming confused, trying to interpret what is not there. It has been reported that people see things such as horses flying through clouds or hearing the voice of dead relatives.

The Mermaid Theory

The myth of mermaids originates thousands of years ago from sailors who had been out in the waters for many months. Without seeing a woman for such long times, they reached a point of desperation where manatees on the rocks appeared as beautiful women with strangely attractive fish tails. This portrays the basic male drive and the way we perceive the world.

This applies to modern days as well. Upon meeting any woman, regardless of their level of attractiveness, a “mermaid clock” begins ticking inside a man’s head. The time that takes for this clock to expire varies for every woman, but ultimately a time comes when the man will see the woman as attractive and will not be able to take his eyes off of her. This is The Mermaid Theory, which thus proves that the attractiveness of a woman to a man increases in direct proportion to the time exposed to her. Or put even more simply, no matter how attractive or unattractive a woman is, eventually a man will want to sleep with her. This process may be accelerated by the usage of alcohol and the level of depravation of the man at the time.

The Mermaid Theory proves to be potentially dangerous, for example when the woman in question is a close friend of the man or even his partner. Sometimes the mental shock that someone once so unappealing is now so beautiful looking may be crippling as well.

True story.

Kiss

Kissing is an act of love seen in cultures across the globe, with its history spanning many thousands of years. There are many theories as to how this act – representing love, affection, friendship and even respect – came about. The two most popular theories are the ideas that early humans in the Stone Age licked each other’s faces to obtain salt from sweat, or that it originated from ancient Romans. Roman soldiers kissed their wives as soon as they returned from war, to check whether there was the smell of alcohol (which was banned for women) or another man.
Using historical evidence from ancient texts from India and old paintings from China, it can be deduced that even in Asia the history of kissing is over 2000~4000 years old.

The human lip contains many nerve endings, making it one of the most sensitive part of skin on the body. Also, kissing stimulates the secretion of dopamine and oxytocin, chemicals responsible for invoking the feeling of love and happiness, causing an electric sensation (research states that the brain interprets it in a similar way to using cocaine).
It has already been proven that kissing lowers perceived stress and frequent kissing between couples lowers cholesterol and strengthens the cardiovascular system. Furthermore, it has been discovered that over 295 colonies of bacteria can be transferred per kiss (95% of which are harmless, but diseases such as glandular fever or herpes can be transmitted this way).
Some believe that the act of kissing came about to simulate the feeling of breastfeeding, an act ingrained in the subconscious mind (the same point is made regarding cigarette use).

This romantic behaviour is also seen in nature. Many bird and mammal mothers transfer pre-masticated food to their young this way, and calves kiss each other after drinking milk to prolong the sensation of breastfeeding. Even insects are found to “kiss”, such as ants that bring up food from their second stomach, the “social stomach”, to feed fellow ants that need food.

Uncanny Valley

(original article by Kingdom of Discord, summarised and modified with permission)

The Uncanny Valley, a term coined by Japanese roboticist Masahiro Mori, is a theory that the more humanistic a robot (or any object) is, the more humans will feel comfortable with it and show empathy and love towards it. However, there is a point where the robot almost completely resembles a person, yet there is something not quite right. At this point, human response to the robot plummets, even falling below the line of neutrality and instead reaching a point where people become uncomfortable around it, and may even become hostile towards it or be afraid of it.

For example, robots such as C-3PO (from Star Wars) that are humanoid yet obviously robotic are met with love and affection from the audience. This also applies to human characteristics, such as Wall-E who shows human emotions that we can empathise with. 
But when the resemblance becomes too similar, such as a prosthetic limb, computer-generated images (CGI) such as characters from The Polar Express, or zombies, people find that there is something “wrong” and will show negative emotions towards it.
The Uncanny Valley also applies to people, especially those with a physical or mental disability that causes them to slide under the line that society names “the norm”.

There are many theories as to why this phenomenon occurs.
Firstly, the further away from human-likeness an object is, the less likely it will be compared to the “human norm”. But objects in the Uncanny Valley are more likely to be measured against “normal” humans, and thus they will be seen as “inferior”, rather than “superior to normal objects”.
Secondly, using the above theory, it can also be suggested that the primal instinct of avoiding mates with some disfigurement is elicited, causing a natural aversion.
Lastly, it may remind the person of their mortality and the fact that they could become something akin to that, invoking fear. The fear may also originate from the thought that they may become even closer to human beings, thus replacing humanity. This idea is seen in the anime Chobits.

The Uncanny Valley phenomenon is used extensively in the genre of horror movies, as people will relate more closely to human-like monsters such as ghosts and zombies than giant monsters. This will cause them to believe that it is more realistic, resulting in heightened fear. Combined with the uncanny feeling invoked by the closeness to a human, it is a potent method of scaring the audience.
It is also thought that the Uncanny Valley explains certain psychological conditions such as racism and the fear of clowns, as there is a primal aversion to those that are slightly different.

Sensory Illusion

The five senses we use to experience the world are simply wondrous. However, thanks to our not-so-perfect brain, these senses can easily be distorted. Illusions are a very good way to show how the brain processes sensory information and there are many fascinating examples.

Almost everyone has seen an optical illusion before, such as Penrose’s endless stairs or the Muller-Lyer illusion. There are countless more examples such as static pictures that appear to be moving and illusions in colour perception (A and B are the same colour). This is caused by the brain not recording images like a camera, but rather processing visual information and reconstructing an image. There are four main types of optical illusions: ambiguous (e.g. rabbit or duck), distortion (Café wall illusion), paradoxical (Penrose triangle) and fictional (only seen in hallucinations or by schizophrenics).

(Do you see the dolphins? Children cannot see the man and woman because they cannot comprehend it, whilst adults cannot overpower the sexual image)

Like vision, every other sense can be fooled in a similar fashion.
Auditory illusions that distort what we hear are fairly common, a good example being the infinitely ascending Shepard scale (which are just a series of the same ascending octave scale). Also, the McGurk effect shows how the brain uses a multimodal approach where it involves both hearing and vision when listening.

There are also tactile illusions. For example, if you pull your top lip to left and the bottom lip to the right, then prod the middle of the lips with a pencil, it feels like there are two. However, the more famous case is of the Phantom Limb, where an amputee’s brain still believes that the limb is there, causing it to “feel” the limb or even feel pain.

The other two senses aren’t as famous in terms of illusions, but definitely exist.
Smell is easy to fool through chemicals as it is the physiological method of detecting smell. It also exhibits olfactory fatigue where it becomes desensitised to a strong smell.
Taste illusions are more fascinating and easily seen. They are caused by two or more tastes forming a synergy to produce a completely different taste. For instance, mixing barley tea and milk produces a coffee milk taste, while cucumber and honey tastes like melons.
A more fascinating illusion involves Miracle Fruit Berries, which contain a substance called miraculin that distorts the taste of sourness to sweetness.

This shows how we can fool all five senses, and learn more about the mysterious organ that is the brain.
