Lie Detection

In developmental psychology, a child’s ability to successfully lie is considered a milestone achievement. This goes to show how lying is one of the characteristic behaviours of human beings. Even a three-year old knows that by lying, they can avoid punishment and gain much more.

There are many signs of deception. Becoming an expert in observing these signs and knowing what they mean can grant the ability to see through lies. The following is a description of some of the changes – both non-verbal and verbal – that people exhibit when lying. Note that these signs are not always definitive and should be used as a reference only. One must carefully deduce whether the signs are there because the person is lying, or whether it is a simple physiological process with no meaning. Here is a simplified list of the signs that will be discussed:

  • faster blinking, avoiding/too much eye contact, dilated pupils, looking up and right
  • sweaty face and palms, fast pulse and blood pressure, flushed face
  • dry mouth/lips, constant licking or pursing lips, swallowing loudly and often
  • looking away or down, tics and twitches in face (eyes, cheeks, mouth)
  • placing hand near mouth (rubbing nose/chin, scratching face etc.)
  • touching neck, pulling at collar, rubbing forearms or hands
  • shoulder shrug, crossed arms/legs, fidgeting, hiding of hands
  • holding hands or clenched fists, unusual movements
  • tucking feet below seat, tapping of feet
  • short, general descriptions (or overly detailed), inconsistencies in detail
  • talking faster and at a higher pitch, emphasising the “truth”

Non-verbal signs are essentially body language – a mean of subconscious communication through which the person signals to another person about their emotions and thoughts. These can be behavioural (avoiding eye contact), physiological (faster heart rate) or cognitive (exaggerating that they are “truthful”). As non-verbal communication makes up 90% of a conversation, it is extremely useful to know what signs to look for and know what they mean. Let us start with the face.

The eyes are considered the window to the soul. This is because the eyes give off so many clues about what the person is thinking, usually subconsciously. A key sign to look for is the frequency of blinking. If the person is blinking much more than usual, it suggests that they are nervous (causing their eyes to dry out faster). Another famous example is eye contact – people avoid eye contact when lying as they are subconsciously “ashamed” of being immoral. However, they may consciously compensate this and make too much eye contact, another sign they are hiding something. Looking up and to the right has been associated with the brain imagining something, as opposed to down and left which is related to recalling true memories. Lastly, the pupils may dilate from the excitement and nervousness.

When a person lies, they tend to be nervous, stressed and excited. This activates the sympathetic nervous system, colloquially known as the fight or flight mode (rapid blinking is related to this). This causes other signs such as sweating, dry mouth, fast heartbeat and blood pressure. Therefore, a liar may be seen licking or pursing their lips to moisten them. Frequent, loud swallowing is also a clear sign of dry mouth. The face may be slightly flushed as well.

As stated above, the person is also subconsciously ashamed of their lying. This causes the person to face away from the person or look down (think of a child who is lying – their innocence makes signs of deception flare up like Christmas lights). Many people place their hand near their mouth (e.g. rubbing their nose or chin, touching their lips), as if the brain is telling the hands to stop the lie from coming out. They also tend to rub their neck or adjust their collar as touching the neck comforts people. Note that scratching the nose is another sign of lying but not the same as rubbing the nose. Scratching is to relieve the itchiness caused by the raised blood pressure irritating the soft tissue of the nose (Pinocchio effect).

Obviously the facial expression would change also, expressing nervousness and mild stress. This may be concealed with a fake smile (when the “eyes don’t smile”) or anger. It is well-known that people exhibit microexpressions – a flicker of emotion expressed in the face – that only shows for a fraction of a second. Although it is hard to spot, it is a direct display of their true emotion. Fascinatingly, the right face tends to react more as it is controlled by the left brain – responsible for the logical and complex thinking required in telling a lie. This may show as a tic or twitch in the eyes, cheek or mouth.

Moving down the body, a classic sign of deception is the shoulder shrug. Shrugging the shoulders is a message they are “unsure” if what they said is true and is seen (subtly) in many cases of lies. The arms may be crossed (a closed position), which shows they are being defensive (a sign of guilt or discomfort). Similarly, the person may be leaning away from the other person.

The hands are just as important as the face when it comes to lie detection. As mentioned before liars tend to touch various parts of their face and neck while telling a lie. Women tend to rub their hands together or their forearm instead of the neck to comfort themselves. Fidgeting is also very important to notice as this is a comforting act too and exaggerating movements are seen also (reinforcing the “validity” of their lie). Usually, people are aware of this fact and attempt to hide their hands in their pockets, behind their back or behind a bag. They may hold the hands together to prevent fidgeting, or tightly clench their fists. Basically, look for unnecessary (or lack thereof) movements as this almost certainly indicates that something is abnormal.
Similarly, the person may cross their legs (defensive), tuck their feet below the seat (distancing from the other person) or tap their feet (nervousness and excitement).

To finish off, here are some verbal cues for deception. People have a tendency to give short replies when lying. They also talk at a faster pace and higher pitch. These are all due to the subconscious want for the conversation to be over as soon as possible (often accompanied by an awkward or angry attempt at changing the topic). On a similar note, they are more hesitant and less fluent in talking, adding many “umm”s and “uhh”s as they try conjure a lie. Words such as “somebody” “somewhere” “everywhere” that encompass a non-specific or broad target are used to try dilute the details of the lie.

Conversely, the more experienced liar tries to make their lie believable by adding excessive detail to their story. For example, asking a specific detail (that they normally wouldn’t notice) would prompt an answer as opposed to an “I don’t remember”. It is also useful to ask the same question again and check for any inconsistencies.
Lastly, if the more the person affirms that they are telling the truth (e.g. “honestly”, “believe me”, “swear to god”), the more likely they are lying.

This list is not exhaustive and there are many tiny details that can be used to help you decide whether someone is trying to deceive you or not. Again, as the signs are not definitive (e.g. they may be thirsty or just nervous talking to you) it should be considered within the context along with other information. However, it is still an extremely useful tool for finding the truth as everybody lies.

Formula Of Happiness

Ask yourself the following questions using a scale from 1 to 10, where 1 is “not at all” and 10 is “to a large extent”:

  1. Are you outgoing, energetic, flexible and open to change?
  2. Do you have a positive outlook, bounce back quickly from setbacks and feel that you are in control of your life?
  3. Are your basic life needs met, in relation to personal health, finance, safety, freedom of choice and sense of community?
  4. Can you call on the support of people close to you, immerse yourself in what you are doing, meet your expectations and engage in activities that give you a sense of purpose?

Add the scores for 1 and 2. This is P for personal characteristics.
The score for 3 is E for existence (health, financial stability and friendships).
The score for 4 is H for higher order and covers self-esteem, confidence, ambitions and sense of humor.
Now input each score into the following equation:

Happiness = P + (5 x E) + (3 x H)

This gives a score out of 100. The greater your score, the happier you are (over 80 is considered a “happy life”). This formula was devised based on a psychology study of 1000 people. It takes into account the various aspects of life that contribute to your overall happiness and emotional well-being. The study showed statistics such as 40% of men reporting that sex made them happy, while 25% of women reported that losing weight made them happy. Men found more happiness in romance, hobbies and a pay rise compared to women.

Although everyone has a different definition of happiness, there is no doubt that there are common “happiness” factors to all of us and this equation tries to objectively quantify how happy you are in life.

Are you happy?

Black And White

The following poem was written by an African child. It was nominated by the UN as the Best Poem of 2006.

When I born, I black
When I grow up, I black
When I go in sun, I black
When I scared, I black
When I sick, I black
And when I die, I still black

And you white fellow

When you born, you pink
When you grow up, you white
When you go in sun, you red
When you cold, you blue
When you scared, you yellow
When you sick, you green

Superbug

Frequently on the media, the word “superbug” is used as if it were the new Black Death or the coming apocalypse. What is a superbug and why is it so feared?
Superbug is the colloquial nickname for drug-resistant bacteria. For example, one of the most famous superbugs is MRSA (methicillin-resistant Staphylococcus aureus). This strain S. aureus, a common bacteria found on skin and inside the nose, is resistant to a powerful antibiotic called methicillin and thus very hard to treat. Unfortunately, MRSA is most commonly contracted in hospital settings as patients are vulnerable to infections (e.g. after surgery) and hospitals are perfect breeding grounds for superbugs.

The cause of a “normal” bacteria turning into a superbug is due to the incorrect use of antibiotics. When antibiotics are used, they wipe out a significant portion of the bacterial population but fail to kill all of them in the first attack. The surviving bacteria are the more adapted ones that are able to withstand the harsh environment for a little longer. If the patient stops taking the antibiotics and the bacteria remains, these “drug-resistant” bacteria multiply to create a second infection that is resistant to the drug that was used previously. In fact, this is a classic example of natural selection in motion, except that the environmental change is man-made.
This is the reason why doctors are reluctant to prescribe antibiotics for diseases such as the common cold or viral diseases, as the risk of developing superbugs is greater than the benefit (which is zero in viral diseases as they do nothing) of the treatment. It is also why a course of antibiotics must be finished even if the patient is feeling well, so that even the surviving bacteria are eventually killed.

To show the potential risk of superbugs, the case of VRSA can be taken into consideration. When MRSA was first discovered, doctors found it very difficult to treat but luckily they had a secret weapon – vancomycin, one of the most powerful antibiotics known to mankind. However, they soon found that S. aureus and natural selection easily overcame this through a new strain called VRSA – vancomycin-resistant S. aureus. Here was a bacteria that could overcome the greatest weapon man had against bacteria, all because people were taking more antibiotics than needed and not taking the full course prescribed.

Thus, one of the growing problems of modern medicine is the development of new drugs so that we can make a comeback in the arms race against bacteria.

Surname

There is an interesting story regarding the history of Japanese surnames – known to be the most numerous in the world as there are over 100,000 surnames in Japan.
It is said that in the late Sengoku period (16th~17th century), a period filled with civil wars, there were so many soldiers who had died that there was a shortage of men. To remedy this, Toyotomi Hideyoshi (who unified the clans in Japan) issued a ruling to all women, stating they must wear a blanket-like cloth on their back and to wear no underwear. If they met a man, they were obligated to have intercourse with them in the hopes of conception. This is the origin of the kimono – a garment that can easily be undone and be used as a blanket outside when required (although now the use is different), and the reason why underwear is not worn with kimono traditionally.

This meant that any surviving males had the luck of having any women they pleased. This resulted in the women not knowing who the father of the baby was and thus they named their babies according to where they were conceived. Out of all Japanese surnames, 80% refer to something geographical: 山本 (yamamoto) – at the mountain, 木下(kinoshita) – under a tree, 竹田 (takeda) – at the bamboo field, 山野(yamano) – mountain plain, 川邊 (kawabe) – next to a stream… and the list goes on.

With their surnames being so ranged and “meaningless”, culturally Japan is not very attached to their own surnames. Contrary to this, the neighbouring countries, Korea and China, place great importance in surnames as it shows the roots of the people. For example, in Korea all families have a book called jokbo where the entire family lineage for the surname can be traced back to the root. Every family member’s name and birth date is recorded along with the generation they are in.
Because of this, the Japanese were perplexed after their invasion why the people were so against changing their names to Japanese. What they did not understand was the pride people have in their names and their cultural heritage, as the same pride is not found in Japan.

Helen

Helen of Troy is infamous for her pivotal role in the Trojan War after she left Sparta for her new lover, Paris of Troy. She was deemed the “most beautiful woman” in the world by Aphrodite, the goddess of love, who made her fall in love with Paris in return for him choosing Aphrodite as the most beautiful goddess.

Helen is said to have been so beautiful that she had “the face that launched a thousand ships” (in reference to the Trojan War and the massive navy of Greece). Using this statement, clever authors such as Isaac Asimov and W.A.H. Rushton invented the “Helen (H)” unit – an international, standardised measurement of beauty. As Helen launched a thousand ships, a milliHelen (mH) of beauty equates to the amount of beauty required to launch a single ship.
For example, according to The Iliad, the total number of ships that joined the expedition to Troy was 1186. This means that Helen had a beauty rating of 1.186 Helens – ergo, capable of launching more than one thousand ships.

The unit also goes both ways as negative Helen units are possible. For example, -1 mH would mean “beauty” (read: ugliness) that drives a single ship away. The units can be subdivided further, such as a picoHelen (10^-12) being the amount of beauty that “tosses an inflatable tube into the pool”.
Another interpretation of the Helen is the number of women that said woman is more beautiful than. For example, during Helen of Troy’s time (1100 BC), about 50 million women existed on Earth. Therefore, 1 Helen is amount of beauty sufficient to be greater than the beauty of 50 million women.

Finally, beauty is considered to be on a logarithmic scale of base 2. Simply put, for beauty to increase by 1H, the woman must be the most beautiful of double the number of women. In practical terms, the most beautiful woman who ever lived (using the cumulative female population of the world) has a beauty rating of 1.34H. The most beautiful of a dozen women would be 0.14H.

How To Calm A Baby

One of the hardest things about being a new parent is how to quell the cries of a newborn. Since crying is their only way of communicating needs, babies cry constantly and this can be extremely distressing for the parents. 
Of course the best way is to deal with what the baby needs, such as food or changing their diaper, but the cause is not always clear. Most parents use the traditional method of picking the baby up and slowly patting or rubbing the baby’s back. By patting at a similar beat to the mother’s heartbeat, the baby feels at ease as it reminds it of the relaxing state within the womb.

There are some other less conventional methods that have been shown to work. For example, turning the vacuum cleaner on or any other white noise (such as the washing machine, rustling a plastic bag or even gargling water in your mouth) has an instant effect of stopping the baby’s cries (NB: usually only works on infants below 3 months of age). The reason being, these noises are at a similar frequency to the noises the baby hears in the womb, such as the mother’s guts moving, blood flowing through the vessels and sounds from the outsides being transmitted through the mother. As the brain remembers such relaxing states for the fist few months, these stimuli induce a relaxing response and calm the baby.
Similarly, turning on rock & roll music (not too loudly) calms the baby in the first few months as they are unable to recognise the words but can still feel the vibration from the rhythm, which again reminds the baby of the womb.

The same principle can be used to simulate other features of womb life. Rocking the baby slowly simulates the sensation when the mother is walking, wrapping the baby in a blanket simulates the warmth and cosy nature of the womb and giving the baby something to suck on like a pacifier induces the powerful sucking reflex which calms the baby.
As a last resort, touching the inside of the ear canal with your little finger causes the baby to become confused about the strange sensation, distracting the baby. Although this method is effective up to 24 months, it is not recommended as it can lead to an ear infection.

On a similar note, when a baby or young child is stubbornly holding on to something, the best method to get it back is for the mother to pretend that they are crying. The child, empathising with the mother and not wanting her to be sad, yields the object in their hand to make her happy. But this method may not work after a while when the child realises you are tricking them.

Dokdo

Dokdo is a small island in the East Sea off the coast of Korea, lying at 131°52´East longitude and about 37°14´North latitude. It literally means “solitary island” in Korean due to its rocky, isolated nature. The island is actually in two parts: West Island and East Island, which are connected by an underground rock formation. 
The island has been Korean territory for two millennia, with records going back as far as the 4th century showing that fishers from Ulleungdo (a much larger island also in the East Sea) documented the existence of the island and fished around the area. The island is also visible from Ulleungdo on a clear day so it would have been easily spotted and recorded.

Despite the incontestable evidence, in the last few decades Japan has been arguing that Dokdo is Japanese territory. The Japanese government denies the current evidence and claims that all evidence is faked. However, the claims made by Japan are extremely obtuse and bearing on childish. There are many reasons they seek control over Dokdo, such as the rich fishing area around it, the abundant hydrocarbon reserve underneath it and also rearing the ugly head of colonialism.

Almost all historical records and maps up to the 19th century clearly indicate the island as “Korean territory”. For example, in Map of Three Adjoining countries by Hayashi Shihei, a Japanese scholar and cartographer, shows the land in the Far east divided in to colours: yellow for Joseon (Korea) and green for Japan. It is one of the earliest complete maps of Japan. Here, the islands east of Korea, including a large island clearly marked “Ulleungdo” and many surrounding small islands, are all marked yellow and labelled “Korean territories”. There are also records of the Shogunate querying the Tottori clan (who controlled the Shimane prefecture at the time) whether Dokdo and Ulleungdo were Japanese islands, to which the Tottori reply “No, those islands have never been under Japanese rule”. Finally, legal documents by the Japanese National Land Registry in 1877 state that Ulleungdo and Dokdo are not under Japanese rule.

Things became complicated in the early 20th century with the Japanese invasion of Korea. Starting from this period, Japanese maps began marking Dokdo (and Korea and Taiwan and all other colonies) as “Japanese territory” after invading each land. But after their defeat in World War II, Japan was forced to return all land that they stole in the war as ordered by the Treaty of San Francisco. This treaty outlined what the new definition for “Japan” would be by drawing their border again. This treaty states that “Japan is defined to include the four main islands of Japan and the approximately 1,000 smaller adjacent islands, including the Tsushima Islands and the Ryukyu (Nansei) Islands north of 30° North Latitude (excluding Kuchinoshima Island); and excluding (a) Utsuryo (Ulleung) Island, Liancourt Rocks (Dokdo) and Kuelpart (Jeju) Island…”.
After the Korean War, the UN set a zone called the Korean Air Defence Identification Zone (KADIZ) to mark the areas to be protected by the air force. The KADIZ also includes Dokdo in its boundaries.

There are hundreds of pieces of evidence that support the rightful ownership of Dokdo as Korean land, yet Japan continues to argue in an attempt to bring back its old habits of colonialism. It is sad to think that after the Colonialism times and the Pacific War, where so many innocent people were sacrificed to fill the greed of a corrupt country, Japan has not learnt a single lesson.

In short, the controversy around Dokdo is essentially the same as someone claiming that your finger belongs to them and arguing that you should go to court to prove that you own it.

Pizza

Pizza is a food that has a diverse range from cheesy, party-purpose takeaway pizzas to classy, traditional woodfire pizzas. Although it is considered an Italian food, the modern pizza could not have been born without America.

The Mediterranean countries have a long history of making flat breads such as focaccia and coca. But one of the most important ingredients in pizza, tomato, was introduced to Europe only in the 16th century from the Americas. However, Europeans thought for some time that the fruit was poisonous and did not use it for cooking purposes. But by the 18th century, the poorer population in Naples, Italy began creating a dish consisting of flat bread with tomato paste, giving birth to the pizza. Pizza was not a luxury food to start with, but rather a poor man’s food as it was simple and cheap to make. There is even a story of how King Ferdinand 1 disguised himself as a commoner to sneak into Naples to indulge in some pizzas – a food banned from the royal court.

Nowadays, it is common to see at least 5 or more toppings on pizza for a rich taste, but the traditional pizza never has more than three toppings (this is still true in Italy). For example, the two main types of pizza considered as the “true pizzas” by Neapolitans, are: the marinara pizza (tomato, garlic, oregano and sometimes basil) and the Margherita pizza (tomato, mozzarella, basil). The story behind the Margherita pizza is that it was served to the Queen Margherita of Savoy (Queen of Italy at the time), thus the name. The pizza represented the Italian flag by using three ingredients: red tomatoes, white mozzarella cheese and green basil. As the Kingdom of Italy had only been formed a couple decades before this, the pizza was highly symbolic (Italy was very passionate about its flag to promote the unification of the various regions after the Kingdom formed). Today the two pizzas are the most popular pizzas in Italy and are officially protected products as “traditional Italian foods”.

The current record for the largest pizza was a pizza made in Johannesburg, South Africa, that had a diameter of 37.4 metres and made of 500kg of flour, 800kg of cheese and 900kg of tomato puree.
