The Battle of the Selfie Sticks: Leave only Footprints, Take only Selfies

It is said that when you visit the Trevi Fountain and throw a coin in it, you will one day return. More precisely, you need to stand with your back to the fountain and toss a coin over your left shoulder. The spell of this magical act must be quite useful because every visit in the past I have thrown a coin into the fountain, and here I am yet again at this hot-spot of global tourism.

Trevi Fountain Money Suckers - The Battle of the Selfie SticksThe fountain was partially closed for tourists because the maintenance crew were sucking up all the coins. The city of Rome donates the thousands of Euros it retrieves from the fountain to the Caritas charity.

More impressive than the 80,000 cubic metres of water that pass through the fountain every day or the fact that it is made from Travertine are the hundreds of tourists that gather around the monument. Jostling for position to take the perfect picture, waving their selfie sticks like a horde of barbarians wielding their swords.

The Battle of the Selfie Sticks

The moral imperative of the contemporary tourist seems to be to “leave only footprints, take only selfies”. The selfie is the irrefutable evidence that you have been to this magnificent place—it provides the selfie taker with ultimate bragging rights. The selfie is the ultimate narcissistic act. No longer do we need to ask a fellow traveller to take a photo of ourselves. The stick has replaced an act of kindness with an act of self-gratification. On the positive side, it does reduce the risk of somebody sprinting away with your camera.

The battle of the selfie sticks was more amusing to watch than the fountain itself. This time, I didn’t throw a coin in the fountain. Whether I will return, depends on the goodwill of the gods of tourism.

The Airport Zombie Lurch: The joys and suffering of long-haul travel

The pleasant anticipation of flying to Europe is quickly squashed once you enter the virtual and bizarre world of the transit airport. Entering the airport is a battle in itself—first you need to participate in the security ritual to ward off the evil demons we call terrorists, then deal with the Australian Border Force, which must be the most unfriendly name for an immigration service. When you then finally enter the airport with a sigh of relief, you run the gauntlet of the duty-free shops. And then, the waiting starts …

The inimitable Douglas Adams expressed the special nature of airports beautifully when he asked himself why nobody ever says that something is “as beautiful as an airport”. Airports are functional structures with the sole purpose of moving as many people as possible along as many shops as possible towards their gate.

Airport zombie lurchWe flew from Melbourne to Rome and had a brief stop in the navel of the world, Dubai International Airport. DXB, as it is known to the initiated, is one of the global hubs where people from all seven continent, bar Antartica, gather on their journey to further destinations. Thousands of travellers waggle through the terminal reminiscent of a gigantic zombie lurch. Travellers are like the living dead and exist outside place and time—jet lagged and tired, but full of anticipation about their final destination.

Philosophers have written insightful books about airports. As Roy Christopher put it: “The airport is a place made up of on-the-ways, not-there-yets, missed-connections. An airport is a place made up of no-places.” Alain de Botton spent a whole week at Heathrow as ‘writer in residence’ and wrote an insightful meditation about  the people that occupy this place. Airports are places where thousands of people gather, but rarely do they meet. De Botton tells the story of these anonymous soles that we see, but never meet.

Finally, after thirty hours of travel limbo, we arrived in Rome. The feeling of being freshly showered, lying on a cool clean sheets after a very long day can only be described in one word, a ‘bedgasm’.

But not for long, time to battle the time difference, overcome our tiredness and explore the eternal city. Ready for the tourism zombie lurch past ancient monuments …

The Art of Deception: Magic as a Theatrical Art

Is magic a form of theatrical art or a whimsical sideshow performance?Magicians are not regarded as artists in the same way as actors, dancers and musicians are. Magic plays a modest role in the world of show business and is more aligned with sideshows and circus than with theatrical art. Most would deny magic the status of an art form as it has a lowly status in the hierarchy of the dramatic arts.1 Not perturbed by their lowly status, magicians themselves often refer to their performances as an art form.

Are magicians artists and is performing magic an art form in the same way that other forms of ‘serious’ theatre are art? Discussing whether magic is an art or not is almost futile as there are many equally valid interpretations of what constitutes a form of art.

As an art form, magic is an informal form of theatre that resides in the niches of contemporary culture. Most people rarely experience a live magic performance and would struggle to recall the names of magicians. The majority of magic performers does not appear on television or works in regular theatres. They perform in many types of venues not traditionally associated with theatre, children’s birthday parties, restaurants, the street, at conventions and so on. This unique nature of magic implies that it cannot be analysed in the same way as you would a traditional theatrical performance. This essay proposes that magic cannot be examined using the traditional concept of theatre but that it is a form of ‘epic theatre’ as conceptualised by Bertold Brecht.

Theatrical Art

Theatre is traditionally considered to be a ‘closed’ Aristotelian form of art, characterised by the unity of time, place and action.2 The objective of ‘closed theatre’ is that the audience to temporarily forgets that they are watching actors on a stage. The role of the writers, actors, directors and others is to ensure the “suspension of disbelief” by spectators. The audience is enticed to believe in the virtual reality staged in front of their eyes. Nineteenth-century French magician Robert Houdin, the father of modern magic, is famous for saying that a magician is an actor who plays the role of a real magician.3 Houdin’s definition of a stage magician matches the Aristotelian concept of theatre. In his view, the objective of magical theatre is to convince spectators that the person they are watching is a real magician, a person that can contravene the laws of physics. From this perspective, a magic show is an Aristotelean art form, assuming the magician can, at least temporarily, convince spectators that she possesses supernatural powers.

However, the closed concept of theatre cannot be generically applied to contemporary magicians. Any intelligent observer realises that magicians use devious techniques to create the illusion that he evokes magical powers. The audience is astutely aware that a conjurer cannot produce playing cards from thin air or cause balls to penetrate solid metal cups. For magic to be considered theatrical art in the traditional sense, it requires spectators to suspend their disbelief. Modern viewers are, however, not able to fully immerse in the magical world created by the magician to the same extent that they are willing to suspend their disbelief when watching a film or play.

The intellectual challenge inherent in magic theatre engenders a tension between the audience and the magician. “How did she do it” is always on the mind of the spectator. The main difference between magicians and actors is that magic performances are often about the adventures of the props in the hands of the magician, while plays and films are about the adventures of the individuals themselves.4 The lack of human interest in most magic makes it almost impossible for disbelief to be suspended. Perhaps there is another way to interpret magic performances.

Magicians and Bertolt Brecht

A significant difference between traditional closed theatre and magic is that conjuring almost always involves direct communication and interaction between the performer and the spectator. In traditional theatre, there exists a so-called fourth wall, an imaginary division between performers and audiences. The fourth wall is an invisible one-way screen placed on the edge of the stage. The audience can see and hear the actors, but the characters played by the actors, cannot perceive them. In a magic show, especially close-up magic, this wall doesn’t exist as spectators form an active part of the performance. “Pick a card, any card”, are commonly heard words in close-up magic shows and the observer participates in the performance. Traditional theatre occasionally breaks through the fourth wall when a character in a play refers to the fact that they are part of a performance. These considerations imply that the Aristotelian idea of theatre does not apply to magic, in particular, close-up magic.

German playwright Bertolt Brecht developed a view of theatre that contrasts the Aristotelian view. One of the techniques he used was the distancing effect (Verfremdungseffekt). This effect happens when an actor, implicitly or explicitly, indicates being part of a performance, deliberately breaking through the fourth wall. In Brecht’s concept of theatre, actors often break through the fourth wall and spectators are not expected to identify emotionally with the characters. In Brechtian theatre, audiences are rationally engaged with the proceedings, which he calls this epic theatre.5

A magic show cannot be analysed according to the rules of traditional theatre but are best interpreted as a form of epic theatre. In magic, there is usually no need for emotion or storytelling. Magic has an inherent story to tell, embedded within its very nature. Each magical effect contains the powerful message that reality is not what it seems to be.6 Magic performances are thus an inherently philosophical form of theatre. The magician temporarily creates a virtual world where miracles are possible. It is in this Brechtian sense that magic theatre can be considered a theatrical form art. Magic is a form of epic theatre in which the magician presents the ordinary in an unusual way. The magician indicates the horizon of reality and creates an intellectual challenge for the audience. Not a simple puzzle to be resolved, but a deeper truth about how we experience reality.

This concept can be demonstrated using two examples.

Fred Kaps

Fred Kaps (1926–1980) is one of the best magicians of the last century. Kaps, the stage name of Bram Bongers, had an inimitable performance style, characterised by flawless technique and an engaging presentation. Kaps is the ultimate conjuring actor, and his performance of The Homing Card is an example of dramaturgic perfection.

In this performance, Kaps is in constant conflict with himself as he experiences a series of escalating emotions. The first time he notices the wrong card he is surprised but ignores the issue. The second time the trick goes wrong, Kaps is embarrassed and tries to figure out what’s going on. The third time the wrong card appears he is disappointed in himself but proceeds nevertheless. The fourth and last time the wrong card appears, he even shows anger and eventually capitulates.

This performance is and example of an Aristotelian form of theatre, but not following Houdin’s concept of the actor playing a wizard. Kaps does not pretend to be a real magician, but a plays the role of a failed stage magician.

Tommy Wonder — Epic Theatre

Another Dutch magician is Jos Bemelmans, better known as Tommy Wonder. Bemelmans wrote two of the most influential books in contemporary magic, in which he thoroughly analyses the dramaturgy of a magic show.7

The spectators in this show actively participate, demolishing the fourth wall. The routine consists of several stages, with increasingly strong effects. A distinctive aspect of this performance is the appearance of the pompom and the pouch under one of the cups. In traditional versions of this trick the final climax is the appearance of fruit or bigger balls. Tommy Wonder’s performance is a high-quality piece of magic where spectators are continuously astonished. The power of the close-up magic is not the proximity between the performer and the audience, but that the audience actively experiences the magic, instead of passively consuming the performance.8).

This performance can not be analysed following the traditional view of theatre, but is a prime example of epic theatre. There is no fourth wall and the performance is not about a story, but about pure illusions. This performance creates an intellectual challenge for the audience, which is what Brecht sought to achieve in his form of theatre.

Magic as Theatrical Art

Perepectives on Magic: A book about scienctific views of conjuringMagic is a form of epic theatre as explained by Bertolt Brecht. Most magic performances are not traditional theatre, in which disbelief is suspended, but performances where the magician conveys an alternative worldview. Magic is not about storytelling or intellectual challenges but, at least temporarily about taking us back to a natural state of astonishment, the child’s world view.9

The Prince and the Purple Banana – Lets Go Crazy!

“Let’s look for the purple banana till they put us in the truck”, Prince sang in his 1984 song Let’s go Crazy. These nonsensical words have generated many discussions about what they mean.

One possible interpretation is that we should break away from our dull, mundane reality. But our deviant behaviour makes other people think we are crazy. Prince wants us to ignore what other people think and to keep doing so until they haul us away to the loony bin.

Contemporary society dictates that madness needs to be separated from the every-day world. Michel Foucault describes the history of madness and the development of the first asylums. In the Renaissance, the mad were portrayed as possessing a kind of wisdom—a knowledge of the limits of our world, the horizon of reason. As the ‘age of reason’ started to develop, anyone that did not meet the strict requirements of rational thought and behaviour was labelled as mad and locked up in institutions.

The song is ultimately about our personal responsibility for creating a meaningful life in an absurd and unfair world. This message is in line with the thinking of Existentialist philosophers. Prince voices this thought clearly in his song:

What’s it all for (What’s it all for)
You better live now
Before the grim reaper come knocking on your door

Prince creates meaning by not following what society deems to be reasonable and rational, advising us to go crazy and nuts. Being different is not a disease. Living on the horizon of reason is necessary to be able to live life in fullness. Prince’s imperative does not necessarily mean that we must party like it is 1999, but that we dare to be different in our thoughts, or to use a well-trodden cliché, think outside the box.

The Real Purple Banana

Banana São Tomé (Purple banana)But perhaps Prince was wrong and purple bananas are not as elusive as he thought. The Banana São Tomé is a species of purple banana.

The fact that purple bananas can exist does, however, not reduce the potency of his lyric and the existentialist message contained in this song.

Let’s go crazy
Let’s get nuts
Look for the purple banana
‘Til they put us in the truck, let’s go!

“I could have painted that”—Complex simplicity in abstract art

Abstract art is often ridiculed by the uninitiated observer—”I could have painted that” are words you often hear whispered in galleries.

This statement contains a hidden argument: This painting could have been created by me because it requires little technique. I am not an artist; therefore it cannot be considered art.

Summer Collection by Jan Nelson is a case in point. The straight horizontal lines are indeed something that anyone with a basic ability to hold a paintbrush ostensibly could recreate. But is this a valid argument against the status of this painting as a work of art?

Abstract Art

Traditional concepts of visual art are focused on skill, with the highest level of skill perceived to be the faithful representation of what we perceive to be our external reality. The history of art seems to follow an evolutionary trajectory from the early beginnings in caves to the photo-realistic oil paintings of the seventeenth century. For the casual observer, this evolutionary process is reversed in the early twentieth century when abstract art makes its entry. The strip of images shown below shows this evolution, starting with a naturalistic painting of a tree.

Dutch artist Piet Mondriaan started his career by painting impressionistic works, such as The Red Tree from 1908, seen second from the left. Mondriaan later became inspired by the cubist movement and painted The Gray Tree in 1911. He experimented further with abstracting the idea of a tree and produced Flowering Apple Tree. Later in his career he became mainly known for his compositions with strict geometrical patterns and primary colours iconic for the De Stijl movement.


Contemporary art is no longer restricted to a copy reality, but a way to interpret reality through the observation and technique of the artist. Originality and visual impact are now more important than mere skill of faithfully reproducing what is seen.

Next time when you hear somebody say that they could have painted this, simply ask: “Why didn’t you?”.

Predicting future behaviour from past events: A magician’s view

In recruitment of new staff an often used golden rule often is that past behaviour is an indication of future behaviour. Businesses rely on reference checks or even Google searches to find out as much as they can about their potential new staff. But, is past behaviour really a good proxy for predicting future behaviour?

A magician’s view

The silent part of the American magician’s duo Penn & Teller broke his usual silence and vow of secrecy when he explained a classical magic trick to a gathering of consciousness scholars.

Teller showed that magicians can use the propensity of the human mind to seek patterns by skilfully changing the method during the routine. Teller beautifully illustrates that in human behaviour, the past is in no way a reliable approach to predicting the future.

Predicting future behaviour in recruitment

it is not logical to think that past behaviour is an indication of future behaviour

We have to be careful when judging a person through second hand information gained from referees, Facebook searches and other forms of overt espionage. People are not billiard balls that operate in accordance with laws of physics. People have free will and can change their behaviour depending on the circumstances they find themselves in. Most importantly, we can learn from our mistakes and grow as people by learning from them. Not hiring somebody who has made a mistake in the past could mean that you miss out on hiring a person with a high level of maturity and an ability to adapt. Therefore, when judging a person, keep in mind the words of Roman poet Horace: “Non sum quals eram”—I am not who I once was.

Tommy Wonder on Religion

Tommy Wonder (1953–2006).

Tommy Wonder (1953–2006).

Dutch Magician Tommy Wonder provides an interesting insight into the nature of religion in Volume I of his  The Books of Wonder (1996).

He gives advice to magicians on what to do when a spectator discovers—or beliefs to discover—the secret to a magic routine:

“I’ve frequently wondered why people sometimes come up with painfully silly solutions and don’t stop to realize it. If they would give the matter more thought they would quickly see that their solution couldn’t possibly work. I believe their reasoning runs something like this: The moment a spectator sees a magical effect that he [sic] doesn’t understand, he is confronted with a problem, a problem that stands square in front of him like a granite boulder … Now if the spectator contrives some solution, in a way he has enabled himself to move the problem. He can roll this boulder out of his way, so that he is no longer confronted by it. The problem seems to be solved … his mind throws a big party. He’s solved the problem!”

This observation from the every day practice of a professional magician shows an interesting psychological mechanism at work. Somebody is presented with a seemingly unsolvable problem, which creates a conflict in the mind. As soon as a solution is presented, no matter how improbable, the conflict seems to disappear. Wonder continues:

“Because his mind is dancing and celebrating its victory, it never stops to realize that it only moved the problem … it still exists in another place.”

The psychological mechanism at work is a process of cognitive dissonance. When a magician makes a ball disappear, there are two observations which seem to have no causal relationship—the ball is there and the ball is gone. It is the job of the magician to hide the actual cause—this causeless event is the magical effect. Humans are inclined to remove any tension between dissonant observations, even if this means inventing miraculous connections.

Cognitive dissonance is often used as an explanation for the emergence of religion in pre-scientific cultures. The idea being that ancient people experienced a cognitive dissonance in their experience of natural occurrences, such as the daily disappearance and re-appearance of the sun. The explanations created to relieve the tension is what we now know as religion. This is, however, only a partial explanation. Although much of religion is provides explanations for the way the world is, for those who follow it religion is also a vehicle to provide meaning to life, something that cannot be provided by science.

Does all cognitive dissonance need to be resolved? Why can we not live with the tension of not knowing—accepting that there are questions for which we do not have an answer, or for which there even might not be an answer? Tommy Wonder touches on this when he argues that magicians should aim to defuse the cognitive dissonance experienced by the spectator, creating suspension of disbelief and giving rise to a feeling that magic really exists—even if it is only for a fleeting moment, as our rational mind quickly takes over, trying to resolve the dissonance.

Theatrical Magic and the Sciences

Perspectives on Magic: A book about scientific views of conjuring.

The past three years I have been studying the relationship between magic and science and studied hundreds of articles about the performance of magic tricks from many different fields of science. From this I found that the relationship between magic and the sciences is bidirectional.

Firstly, magicians use the principles of science to create the illusion of magic. They use the principles of psychology, physics, linguistics, engineering and so on to perform their tricks. The second relationship between magic and science is that Scientists study what magicians do. For example, psychologists try to find out how people can be deceived, occupational therapists try to help people improve people’s lives by teaching them magic tricks and scholars in the field of gender studies develop ideas on why so few women are involved in the performance of magic.

For my Perspectives on Magic project I have created an annotated bibliography of scientific research into theatrical magic. The table below provides an overview of the relationship between theatrical magic and the different fields of science. The middle column shows the fields of science used by magicians to create the illusion of magic. The last column shows the fields of science which have studied magic performances.

What can Pigeons teach us about Gambling Addiction

Gambling addiction is a often debated social problem. A lot has been said in Australia about the measures in place to combat gambling addiction. Specially slot machines, poker machines, or whatever they are called in your country, are causing financial problems for many people around the globe. These machines are programmed to be addictive as they tap into foundational psychological mechanisms.

Following the theory of instrumental conditioning, our behaviour is motivated by rewards and punishments. This is the basic mechanism used to educate children, the infamous carrot and stick approach.

The Psychology of Gambling Addiction

With a poker machine, every time we press a button there is a predefined, albeit unpredictable, probability that we are rewarded for that behaviour. In instrumental conditioning this is called a variable-ratio schedule of reinforcement. This method has proven to be very addictive. Even animals in experimental situations have been seen to become addicted to the conditioned behaviour. Watch the video below to see how gambling operators tap into non-rational drives to make us addicted to gambling.

We are using this same mechanism to change our cat Stinkey’s behaviour. She drives us crazy every morning in an attempt to get some canned food. Because we irregularly reward her behaviour we introduced a variable-ratio schedule of reinforcement, which leads to addictive behaviour. Stinkey became addicted to begging for canned food.

We recently started to give her a little bit every night and create a fixed-ratio reinforcement schedule and the obsessive begging has quickly extinguished.
