TL;DR

(Too Long; Didn’t Read)

Studying magic tricks can teach us about other things too.

What can EdTech Startup Founders learn from Professional Magic?

At least, that’s what I took away from reading How Magicians Think by Joshua Jay. Longer post linked below.

Full Post

My in-laws kindly gifted me with a copy of How Magicians Think by Joshua Jay, which I finished reading a few days later. I wouldn’t consider it universal reading, since magic tricks and the magician’s profession are niche topics (and niche experiences, as the book describes), but I found it immensely rewarding in three respects:

  1. As an invitation to visit a “secret” professional world.
  2. As a rough theory of when and why magic tricks work.
  3. As an exploration of the interplay between craft and art.

The Secret World of “Magic”

Magic is intrinsically secretive — evoked astonishment often rests on audience ignorance or misperception of key details of what they’ve witnessed, but it’s also just a small community at the top. Like most performing arts, a small number of performers are blowout successes, a larger pool eke out a modest living doing local shows, and even the group of semi-professional and amateur hobbyists only make up a small portion of the population (my guess would be somewhere between .1% and 1%). Most world-class magicians know each other, and because most travel extensively for work, these unique peer-friendships create a tight-knit and somewhat exclusive community. What does this look like?

I got a taste of this in academia (the world’s experts in a topic invariably all know each other, at least by name), but the book really drove home how small the world can be. In any field where ideas matter and the exchange of them is mutually beneficial, there will form a community of practice that determines the culture of the field in practice, and not just in ideal.

A Working Theory of Magic

To quote, as the book did, Teller (of the world-famous Penn&Teller duo): “You will be fooled by a trick if it involves more time, money and practice than you (or any other sane onlooker) would be willing to invest.”

Most tricks come down to an apparent contradiction between what the onlooker believes is possible (or physically expects) and what actually happens. Like a good punchline, the subversion of expectations creates a sudden reconsideration of what came before. This contradiction is generally achieved by leading viewers to make assumptions that are incorrect (e.g. gimmicked props or sleight-of-hand moves are more than they appear), to incorrectly generalize or remember their observations, or to miss - without realizing it - key pieces of information they might have otherwise perceived. (That’s an incomplete and overlapping list from me that at least paints a picture of the category of phenomena I’m trying to describe.)

Some highlights from the book include parts of David Blaine’s acts that blur the line between “stunts” and “tricks”. For example, there’s a part of his show where David sews his own lips shut (a chosen card is later revealed inside). According to Josh (the author), there’s no trickery involved; David just sews his own lips shut. But many audience members don’t believe anyone would ever do that, so they walk away with a mystery where there really wasn’t one.

There are also lots of examples in the book where magicians have developed an incredibly nuanced skill (e.g. dealing from the middle or bottom of the deck in a way that looks almost identical to dealing from the top, or keeping tiny gaps between distinct packets of cards in a stack in their hands) through extensive practice.

But in many cases, the trick doesn’t really lay in the hands of the performer nearly as much as it rests in the assumptions people make about the physical world in order to operate efficiently in everyday life. Part of why tricks with cards are so prevalent in magic performances is that they are common enough that people have unsuspicious perceptions of what they are and how they work, but they are fundamentally designed to conceal information (all the backs should be identical, obscuring the position of any card in a face-down spread or stack). Furthermore, because cards are pliable and much thinner than they are long, they can be hidden in the hand, behind other cards, and in many other locations. Finally, because our attention is drawn to distinct information, we are easily misdirected to focus on face-up cards, rather than face-down ones.

Magic as Craft and Magic as Art

On the one hand, practicing a particular technique for tens of thousands of repetitions is sometimes necessary merely to sustain the illusion of a particular trick. On the other hand, flawless mechanical execution does not necessarily make a trick entertaining. Josh (the author) spends a number of chapters reflecting on what it takes to create a successful act, beyond mechanically sound tricks.

The first thing he notes is that tricks need to have an internal logic and narrative flow. In many ways, this is the actual substance of the trick. Not just surprise, but the suggestion of a cause-and-effect relationship (however impossible) that gives a reason for the effect. In many tricks, this is a vague explanation (the magician/object/audience have supernatural abilities) where the effect results in a surprising convenience (or fulfillment of a character trait). Josh gives the example of a trick that appears to turn a banana into a bowling pin. By itself, this is just a bizarre and random twist. But if the pin is actually one missing from a existing set, the effect suddenly “makes sense”.

Beyond that, Josh reflects that good acts combine tricks to appeal to an audience metaphor. The trick pulls a rabbit from a hat, but the audience sees the creation of life. The trick saws a woman in half (and restores her), but the audience sees the women’s rights movement and the aftermath of World War I. Flight represents freedom, vanishing represents loss, mind reading is the opposite of loneliness (or surveillance, or any number of other contextualized interpretations).

At the highest level, magic tricks become a vehicle for artistic expression, and the lines between various forms of performance art are blurred. Is this a magic show or a staged monologue about grief that happens to feature magic tricks? What about a one-act play, pantomime, or dance? Magic is uniquely intellectual, in that it manufactures (however ephemerally) astonishment and wonder, but there’s an expansive buffet of combinations with other emotional flavors. There are world-class acts that engage fear, horror, suspense, love, delight, nostalgia, ennui, sadness, or mirth.

In the hands of a master, magic becomes a tool for self-expression, not just an end in itself. Local entertainers may reprise the old classics, but on the world stage, every great performer’s act is unique. Methods and inspirations may be shared, but the whole is distinct and greater than the sum of its parts. To put my own words in Josh’s mouth, magic becomes art when the act is “about something”. When I reflect more broadly, I think this is a relevant distinction in most fields. While we sometimes use “art” to refer to what is actually applied abstracted experience (and maybe better termed “abstract craft”), I think fiction, visual media, and even a person’s life can cross from being productions to being art when they start being “about something”. Not that all art is beautiful, but it becomes relevant to judge it on its artistic merit, and not just its execution.

What Can Other Fields Learn from Magic?

At least, that’s what I think.
