Morse Code

In 1825, an artist by the name of Samuel Morse was travelling to a city far from his home to paint a commission. While working on his painting, he received a letter from his father, which informed Samuel that his wife was ill with an infection. The next day, another letter came, but this time detailing his wife’s sudden death. Upon receiving the letter, Morse immediately returned to his home as fast as possible, but he arrived after they had already buried his wife. This was the age before fast long-distance communication, where messages could only be sent as fast as the horses that carried them.

Frustrated by the inefficient communication methods of his time, Morse became dedicated to devising a better way to send messages over long distance at a much faster speed. After intensive studying of electromagnetism, Morse eventually developed the first concept of a single-wire telegraph. The telegraph could send electrical signals of variable length at fast speeds down wires with a simple button.

Together with the telegraph, Morse devised a code alphabet so that messages could be sent encoded into short and long signals on the telegraph. A dot (“dit”) represents a short press, a dash (“dah”) represents a long press (three times longer than a short press). Each letter is separated by a space the length of 3 dots. Words would be spaced out by a slightly longer pause – the length of 7 dots. Morse designed the code to be efficient and so he made the most common letters (E, I, S, T and so forth) the shortest in length.

Reverse Psychology

If you tell a child not to do something, chances are he or she will do it. This is a simple rule of parenting that everyone has experienced at some point in their lives. People (especially children and teenagers) are wired in a certain way so that if they are told they cannot do or have something, they react by wanting it more. They then rebel by reasserting their freedom and express anger towards the person restricting their freedom. This is a natural response for a person that is beginning to develop a sense of self and ego, as they feel an instinctive desire to protect their right to free will. This psychological phenomenon is known as reactance.

Although reactance can be very troublesome and annoying to deal with, you can easily turn it around to your advantage if you understand the basic principles behind the effect. Under the assumption that a child will always react to your commands and advice by doing the opposite, we can deduce that if you say the opposite of what you want, they will end up doing what you want. This is reverse psychology. It is a surprisingly effective method of manipulation, especially in those with high reactance (usually children or those who are as immature and stubborn as children).

It has been scientifically proven that reverse psychology is extremely effective in children, as they would rather protect their (perceived) free will than avoiding study or not eating their greens. An example of reverse psychology would be telling a child to stay home when they actually want them to go out and play. However, reverse psychology is not the most ideal way of parenting as it reinforces the idea that it is okay to do the opposite of what you ask, thus undermining your authority.

Reverse psychology works just as well in adults when used right. For example, using a strong imperative tone against a person effectively assaults their ego, which provokes their natural instinct of reactance. If you are not in a position of authority and the person has the option to defy you, it is likely that they will revert to an irrational teenager and do the opposite of what you commanded. However, repetitive use of reverse psychology may lead the person to think that they are being manipulated, causing them to nullify it by reverse reverse psychology. Reverse psychology can be a double-edged sword if this happens, so it is important to know when it is most likely to be effective.

Psychological reactance is more likely to arise if the restricted option appears more attractive and important. The greater the restriction of freedom, the greater the psychological reactance. Also, arbitrary threats produce high reactance as they do not make sense, making people more rebellious. It is important that reverse psychology be used subtly and sparingly on people who are resistant to direct requests. Mastery of the above skills will help you manipulate a person into doing your bidding under the illusion that they are acting on their free will.

Earworm

Everyone experiences the phenomenon of a tune being “stuck” in one’s head. This is when an addictive song or piece of music seems to play over and over in someone’s mind even when they are desperately trying to forget it. The Germans call this phenomenon ohrwurm, which translates into “earworm”. 

Having an earworm is not necessarily a pleasant thing, as the person with it may become irritated or agitated by the piece of music. It has been noted that the condition is much more common in people with obsessive-compulsive disorder (OCD), suggesting that earworms may be caused by the brain subconsciously obsessing over the piece of music. 

Because it is so common and addictive, earworms are extensively used in marketing in the form of hooks – music designed to stick in people’s heads. By associating the hook with the marketed brand or product, people cannot stop thinking about it and this subconsciously affects their buying habits.

The concept of earworms is also popular in literature, where authors become creative and explore the “potential” of an earworm. For example, Arthur C. Clarke wrote a short story titled The Ultimate Melody where a scientist invents a melody that compels the brain to become enraptured by it through synchronising with brainwave patterns. Interestingly, the scientist creates the melody simply to escape the barrage of pop music filled with hooks and catchy tunes. Ultimately, he is found catatonic as the melody completely takes over his mind.
