The MICE Quotient is Orson Scott Card's way of deciding where a story should begin and end, by asking which of four elements matters most to it: milieu (the world), idea (a question), character (a change in someone) or event (a world out of order). Card: "All stories contain four elements that can determine structure: Milieu, Idea, Character, and Event. While each is present in every story, there is generally one that dominates the others."
He set it out in Characters and Viewpoint (1988), in a chapter called "What Kind of Story Are You Telling?", and again in How to Write Science Fiction and Fantasy (1990). Quotes below are from those two books, both from Writer's Digest Books.
What Does MICE Stand For?
| Letter | Element | What it covers |
|---|---|---|
| M | Milieu | "the world surrounding the characters", from the landscape to "everything from weather to traffic laws" |
| I | Idea | "the information that the reader is meant to discover or learn" during the story |
| C | Character | who the people are, and above all a change in who one of them is |
| E | Event | something wrong with the world, and the struggle to put it right |
Every story has all four. The question is which one the story is really about, because that one sets the shape.
How Does Each Type of Story Begin and End?
This is the practical heart of it. Each element comes with its own natural beginning and ending.
Milieu. Card's structure for the pure milieu story: "Get a character to the setting that the story is about, and then devise reasons for her to move through the world of the story." It begins when the character arrives, "when the stranger arrives", in his words. It ends when they leave, or as Mary Robinette Kowal summarises a classic one, "they have to get in, they have to get the princess, they have to get back out."
Idea. "The Idea Story begins by raising a question; it ends when the question is answered." Mysteries are the obvious case, and Card puts caper stories here too. His advice to a writer who loves the puzzle: "begin with the question."
Character. It begins "close to the point where the main character begins to attempt to change his role, and ends at the point where the struggle ends." Card names The Member of the Wedding as a character story, and the Indiana Jones films as stories that are not. He also warns against starting years too early: few things are more tedious than a character story that begins long before the change does.
Event. "In the Event Story, something is wrong in the fabric of the universe; the world is out of order." It ends where a new order is established, "or, more rarely, where the old order is restored, or, rarest of all, where the world descends into chaos."
Why It Matters: The Promise to the Reader
How a story begins tells the reader what kind of story it is, and so what ending to wait for. Card's point about the idea story: if it begins as one, the reader expects it to end when the question is answered. Open on a murder and then spend the last third on the detective's divorce, and the reader feels cheated, however good the writing is.
So the MICE Quotient is less a plot formula than a check. Find the element your opening sets up, and make sure the ending pays off that one.
What Is MICE Nesting?
A novel rarely runs on one element. It opens several threads, and the usual advice is to close them in reverse order: the last thread opened is the first closed. That nesting rule comes from Mary Robinette Kowal on the Writing Excuses podcast, not from Card's books. She compares it to "nesting tags in programming" (episode 6.10, summer 2011) and calls it "first in, last out" (episode 16.40, autumn 2021): "if you begin milieu and then you open an inquiry, to close the inquiry and then you close the milieu."
Her name for the I is Inquiry, which keeps the letter but makes the point that it starts with a question.
She explains why the order matters with The Wizard of Oz. Dorothy gets the answer ("ruby slippers will carry you home") before she leaves Oz, and the hourglass scene, with Aunt Em calling for her, "exists to remind you that the status quo is still disrupted." Close the longest thread first and, in her words, "there's a tension drop."
A Worked Example
Wren goes to the island where her grandmother kept the lighthouse.
- Milieu opens. Wren steps off the ferry onto the island.
- Inquiry opens. In the keeper's logbook, the last week before the storm has been torn out. What happened?
- Inquiry closes. She finds the pages in the lamp room: her grandmother kept the light burning all night to guide a lifeboat home.
- Milieu closes. Wren takes the ferry back, the logbook in her bag.
The milieu opened first, so it closes last.
How Do You Track MICE Threads in Deckle?
Deckle is a novel-writing app, and its Outliner is a board of cards, one for every document in the book, each with a synopsis. Labels turn it into a map of your threads.
- Open the Outliner on the Draft and add a card for each scene with Add › Scene.
- In each synopsis, write which thread the scene opens or closes, and how.
- Make a label for each thread, such as "Milieu" and "Inquiry" (the pencil beside Status in the Inspector's Properties opens Edit labels & statuses). Give each label its own colour.
- Set the label on every scene that opens or closes that thread.
- Switch the Outliner to its list and read the colours top to bottom. The pattern should mirror itself: the first colour to open is the last to close.
The Outliner is also where you move a scene when a thread closes in the wrong order. For what happens inside each of those scenes, scene and sequel is the classic pattern, and for the larger shape of the book, the three-act structure can sit above the threads as folders.
Common Mistakes
- Opening one kind of story and ending another. A question in chapter one is a promise. End on the answer.
- Starting a character story too early. Card's point: begin near the attempt to change, not with the character's childhood.
- Closing threads out of order. Resolve the big early thread first and the rest of the book loses its tension.
- Treating the four as genres. A fantasy can be a character story and a mystery can be a milieu story. The element is about shape, not shelf.
- Crediting Card with nesting. The four elements and their beginnings and endings are his. The nesting rule, and the name Inquiry, are Kowal's.
FAQ
Who created the MICE Quotient?
Orson Scott Card, in Characters and Viewpoint (1988) and How to Write Science Fiction and Fantasy (1990).
What does MICE stand for?
Milieu, Idea, Character and Event. Mary Robinette Kowal calls the I "Inquiry."
Can a story have more than one MICE element?
Every story has all four. Card's point is that one usually dominates, and that one decides where the story should start and end.
What is MICE nesting?
Opening several threads and closing them in reverse order, last in, first out. The rule comes from Kowal on Writing Excuses.
Is the MICE Quotient only for science fiction?
No. Card first set it out in a general book on character, Characters and Viewpoint, and his examples include The Member of the Wedding.
