I came to Robert McKee’s Story looking for help with scripting — for language to improve the patter and narrative in my routines. What I found instead was a structural insight that reframed what I thought magic fundamentally was.
McKee is a screenwriting teacher. His book Story is a dense, often brilliant treatment of narrative structure — how stories generate meaning, how audiences engage with characters, how scenes work, what turning points are, why certain narrative choices produce emotional engagement and others don’t. It’s not a magic book. It wasn’t written with magic in mind.
But one concept in particular — what McKee calls the gap — maps onto the mechanics of magic with a precision that feels like he was describing it from the inside.
The Gap in Story
McKee’s concept of the gap emerges from his analysis of how scenes work. A scene, in his framework, begins with a character who has a desire and takes an action to satisfy that desire. That action creates an expectation about what will happen next.
Then reality responds. And the critical question is: does reality respond as expected?
In bad stories, it does. The character acts and the world behaves predictably. Expectation is met. The scene moves forward without friction. Nothing is learned, nothing changes, nothing is at stake.
In good stories, reality responds unexpectedly. There’s a gap between what the character (and the audience) expected and what actually happened. That gap is the engine of the scene. It’s where drama lives. It’s what generates the question that drives the audience forward: given this unexpected result, what will happen next?
The gap is not just a useful device. McKee argues it’s the fundamental unit of storytelling. Every compelling scene, every turning point, every meaningful narrative moment involves a gap between expectation and result.
The Magic Translation
The moment I read this, I stopped and reread it. Because the gap between expectation and result is not just the engine of story. It’s the definition of a magic effect.
A magic effect is: the audience forms an expectation (based on their understanding of how the world works, on what they’ve been shown, on what they’ve been led to believe is possible) and then reality violates that expectation. The thing they expected doesn’t happen. Or the thing they didn’t expect does.
The gap between the expected and the actual is not just an element of magic. It is magic. The gap is the trick.
This seems obvious once stated. But the implications go well beyond the restatement.
What This Means for Effect Construction
If the gap is the trick, then the size and quality of the gap determines the size and quality of the trick.
Two things determine the gap: the expectation you build, and the reality you deliver.
Most attention in magic goes to the reality side — to the method, to the sleight, to the technical construction of the impossible outcome. This makes sense because the impossible outcome has to actually be delivered, and that requires skill.
But McKee’s framework suggests that equal attention should go to the expectation side. What is the audience expecting, and exactly? How specifically have you built that expectation? How committed are they to it?
A trick that delivers an unexpected outcome against a vaguely built expectation produces a small gap. The audience wasn’t that invested in the expectation, so its violation doesn’t produce much.
A trick that builds a very specific, strongly held expectation and then violates it precisely — the gap is enormous. The violation is proportional to the investment in the expectation.
This means the work of setting up a routine — the framing, the apparent tests and demonstrations, the careful leading of the audience to a specific prediction — is not preamble. It’s the construction of the expectation that makes the gap possible. It’s half the trick.
The Quality of the Expectation
McKee distinguishes between expectation and hope. The audience doesn’t just form neutral predictions; they form predictions with emotional stakes. They hope for certain outcomes. They fear others.
In story, the gap is most powerful when it violates not just the intellectual expectation but the emotional hope. The character did everything right and still lost. The person who appeared trustworthy betrayed them. Reality refused to cooperate with the moral order the audience was invested in.
In magic, there’s an analogue. The audience’s expectation often has an emotional component: they believe (or believe they believe) that certain things are impossible. When that belief is violated, it’s not just cognitively surprising — it’s emotionally disorienting. The world doesn’t work the way they thought it did.
This is why the best magic leaves people genuinely unsettled, not just impressed. Impression is the response to technical skill. Genuine disorientation is the response to a fundamental expectation violation. The latter is rarer and more powerful.
Building toward the latter requires understanding what the audience genuinely believes, not just what they predict. Genuinely believed impossibilities make the best targets for gaps.
The Gap Over Time
McKee describes how the gap generates drive: the unexpected result creates a question, and the audience is driven forward by the need to see that question answered. The gap doesn’t close immediately — it stays open across scenes, driving the narrative.
In magic, this translates to the principle of sustained impossibility. The effect shouldn’t just produce a gap and close it. The best effects leave the gap open in the audience’s mind. The impossible thing happened, and the audience carries the unanswered question of how with them — sometimes for years.
I’ve had the experience of people coming up to me months after a show to tell me they’re still thinking about something that happened. Not trying to figure it out in a frustrating sense, but carrying the impossibility as a productive question, a permanent small anomaly in their model of how things work.
That’s the gap doing its work long after the performance. The expectation was so specifically built and so cleanly violated that the mind can’t fully process it, and instead keeps it open, returning to it.
Designing the Gap
The practical implication is a restructuring of where attention goes in effect design.
I used to design from the end backward: here is the impossible thing I want to deliver, now how do I get there? The expectation was built as preamble, often as efficiently as possible, to get to the real business of the method and the outcome.
Now I design from the gap: here is the gap I want to open, and here is the exact expectation I need to build in order for that gap to be as large and as clean as possible. The expectation architecture becomes primary. The method becomes the infrastructure for delivering the gap.
This doesn’t change what the audience experiences as the “trick.” It changes what the designer thinks the trick actually is.
The trick is the gap. Everything else is in service of the gap.
McKee was writing about screenplays. But the principle doesn’t care what medium it’s applied to. The gap is where story lives. The gap is where magic lives. They might be the same thing, viewed from different angles.
If the gap is the trick — if what matters is the distance between expectation and result — then what the audience is following isn’t the card or the coin or the predicted word. It’s something underneath all of that. Robert McKee has a formulation for this that’s changed how I think about every routine I do.
