You remember the scene. Joy, Sadness, and Bing Bong stumble into a literal "Danger" zone in Riley’s mind. Suddenly, they aren't rounded, 3D characters anymore. They're Picasso-esque smears. Then they’re 2D shapes. Finally, they’re just... lines.
That’s Inside Out abstract thought in action.
Honestly, it’s one of the gutsiest moves Pixar ever made. Most kids' movies stick to bright colors and slapstick, but Pete Docter and his team decided to visualize a complex cognitive leap that usually happens around ages 11 to 14. It’s not just a trippy visual gag; it’s a representation of how our brains learn to strip away the "noise" of the world to find the core concept underneath.
If you’ve ever wondered why your pre-teen suddenly started arguing about "justice" or "fairness" instead of just crying because they lost a toy, you’re seeing abstract thought develop in real-time. It’s messy. It’s weird. And in the movie, it’s almost fatal.
The Science Behind the "Deconstruction"
In the film, the characters go through four distinct stages of abstraction: non-objective fragmentation, deconstruction, 2D, and finally, "non-figurative" (the line).
This mirrors what psychologists like Jean Piaget studied for decades. According to Piaget’s stages of cognitive development, Riley—at age 11—is transitioning from the "Concrete Operational Stage" to the "Formal Operational Stage."
Think of it this way. A 7-year-old knows that if you hit a glass with a hammer, it breaks. That’s concrete. But a 12-year-old starts to understand the rule behind it: "Fragile things break under force." They can apply that rule to things they can't see, like a fragile friendship or a fragile ego.
When Joy and Sadness start falling apart in that room, they are literally losing their "concrete" shapes. They are becoming ideas.
Dr. Dacher Keltner, a psychology professor at UC Berkeley who consulted on the film, has spoken at length about how the movie tried to ground these metaphors in actual neuroscience. While we don't have a literal room in our brains where we turn into polygons, we do have the prefrontal cortex. This is the "CEO" of the brain. It’s the part that handles the heavy lifting of Inside Out abstract thought, allowing us to plan for a future that hasn't happened yet or understand metaphors.
Why Does Abstract Thought Feel So Dangerous?
In the movie, the "Abstract Thought" room is a shortcut that turns into a trap. There’s a reason for that.
Processing the world through abstractions is exhausting for a developing brain. It’s a shortcut because it allows us to group massive amounts of data into single words—"Loneliness," "Betrayal," "Hope"—but it’s dangerous because it takes us away from reality.

I’ve seen this happen with kids. They get so caught up in the idea of something that they lose the actual thing. Riley does this throughout the movie. She isn't just "sad about moving"; she’s grappling with the abstract loss of her identity as a "Minnesota girl."
The Stages of the Scene Explained
- Stage 1: Fragmentation. This is where the characters start looking like broken stained glass. In cognitive terms, this is the brain breaking down an object into its component parts.
- Stage 2: Deconstruction. They lose their "depth." This is the brain stripping away irrelevant details. You don't need to know what color a stop sign is to understand the concept of "Stop," but your brain had to learn to ignore the shade of red to focus on the command.
- Stage 3: Two-Dimensionality. They become flat. This is the pure symbol.
- Stage 4: The Line. The ultimate abstraction. A single point or line representing a complex entity.
It’s genius. It’s basically a crash course in art history and developmental psychology crammed into two minutes of animation.
The Role of Bing Bong in the Abstract
It’s no accident that Bing Bong is the one who leads them into that room.
Bing Bong is an imaginary friend—he is, by definition, an abstract thought. He doesn't exist in the physical world. He is a composite of a cat, an elephant, and a dolphin, made of cotton candy. He represents the early, "magical" version of abstraction.
But as Riley grows up, her Inside Out abstract thought needs to become more sophisticated and less "imaginary." The tragedy of the movie is that for Riley to gain the ability to think deeply and complexly, she has to lose the whimsical, concrete version of her imagination. Bing Bong has to be "deconstructed" for Riley to evolve.
It’s heavy stuff for a movie about talking emotions.
Why This Matters for Adults Too
We think we’ve mastered this, but most of us are still stuck in the "fragmentation" stage half the time.
Think about how you handle a "bad day." A concrete thinker says, "I spilled my coffee and missed the bus." An abstract thinker says, "Nothing ever goes my way."
The second one is an abstraction. It’s a generalization. It’s a way of turning a series of concrete events into a "theme" for your life. The problem is that when we over-abstract our problems, they become much harder to solve. You can clean up coffee. You can't "clean up" the feeling that "nothing ever goes right."
Pixar’s depiction reminds us that while abstraction is a sign of maturity, it’s also a place where you can get lost if you stay too long. You need to be able to turn back into a 3D person eventually.
Actionable Steps for Navigating Your Own "Abstract" Brain
Understanding how your brain categorizes information can actually help you manage stress and improve your focus. You don't need a "Control Center" in your head to make these shifts.
Identify the "Concrete" when you’re overwhelmed.
When your brain starts spiraling into abstract "danger zones"—thinking things like "I’m a failure" or "This will never work"—stop. Force yourself back into 3D. What are the specific, concrete facts? You aren't "a failure"; you missed one deadline. You aren't "unlovable"; you had one bad date.
Use "Deconstruction" for learning.
If you’re trying to learn a new skill, act like the Abstract Thought room. Strip away the fluff. What is the "2D" version of the task? If you’re learning a language, don't worry about the "3D" beauty of the literature yet. Find the "line"—the basic grammar structures that hold everything else up.
Watch for "Two-Dimensional" thinking in others.
We often turn people we don't like into 2D characters. We strip away their complexity, their history, and their "depth" until they are just a "villain" or a "jerk." When you catch yourself doing this, try to "re-render" them. Add the 3D details back in. It’s much harder to stay angry at a complex human than at a flat shape.
Value the "Bing Bongs" of your mind.
Don't let your ability to think abstractly kill your creativity. Sometimes you need to leave the "Formal Operational Stage" and go back to being a little bit "concrete." Play with LEGOs. Paint. Do something where the physical, tactile world is the only thing that matters.
The transition into Inside Out abstract thought is a one-way street in the movie, but in real life, we can move back and forth. We need the lines and the shapes to understand the big picture, but we need the 3D, colorful, cotton-candy-scented mess to actually live.
Stay in the 3D world as much as you can, but don't be afraid to take a shortcut through the abstract when you need to see the "lines" more clearly. Just make sure you know the way out before the "train of thought" leaves the station.
Next Steps for Deepening Your Understanding:
- Analyze your self-talk: For the next 24 hours, notice when you use abstract labels for yourself ("I am lazy") versus concrete descriptions ("I haven't started the laundry yet").
- Re-watch the sequence: Look for the specific art references—the transition from Cubism to Minimalism is intentional and tells a story of its own.
- Observe the "shift" in kids: If you have children, listen for the moment they stop asking "What is that?" and start asking "Why is that?" That's the door to the Abstract Thought room swinging open.
