We like to think we see the world as it is. We don’t. We see a version of it, filtered through invisible assumptions we inherited from our culture, our teachers, our moment in history. The philosopher Thomas Kuhn spent his career pointing out this uncomfortable truth: we’re all trapped inside paradigms—ways of seeing—that feel like reality itself but are actually just one possible interpretation among many.
The scary part? You can’t see the bars of your cage.
The Day Einstein’s Universe Collapsed
Picture a physicist in 1900, confidently explaining how the universe works. Space is absolute. Time is absolute. Matter behaves according to Newton’s elegant laws, which have predicted planetary motion for two centuries. Everything makes sense. The universe is a vast clockwork mechanism, and we’ve figured out how to read the time.
Then Einstein shows up and says: actually, time bends. Space curves. Nothing is absolute except the speed of light. Your “common sense” about how reality works? Wrong at a fundamental level.
But here’s what’s interesting: Newton’s physics didn’t stop working. Apples still fell. Planets still orbited. The equations still predicted outcomes with stunning accuracy. So what changed?
The paradigm changed. We started asking different questions. We looked for different things. We accepted that reality could be weirder than our intuitions suggested. And suddenly, phenomena that were invisible or impossible under the old paradigm—black holes, GPS satellites, nuclear energy—became not just visible but obvious.
Kuhn’s insight was that this isn’t unique to physics. It’s how all human knowledge works. We don’t gradually accumulate truths like pennies in a jar. We operate within paradigms until they stop working, then experience revolutionary shifts where everything we thought we knew gets recontextualized.
The Invisible Framework
Your paradigm is everything you don’t question. It’s the water fish don’t know they’re swimming in.
Consider something as simple as mental illness. For centuries, hearing voices or experiencing severe melancholy meant you were possessed by demons or suffering from an imbalance of bodily humors. Doctors would drill holes in skulls or prescribe bloodletting. These weren’t stupid people—they were brilliant physicians working within a paradigm that made perfect sense given what they “knew” about how bodies and minds worked.
Then the paradigm shifted. Mental illness became a medical condition. Then it became a chemical imbalance. Now we’re shifting again toward understanding it as a complex interaction between genetics, environment, trauma, and neurobiology. Each paradigm reveals different treatment possibilities and hides others.
The catch? People operating inside each paradigm couldn’t see it was just one way of looking at things. The demon-possession theory wasn’t a quaint metaphor to medieval doctors—it was obvious reality. The chemical imbalance model isn’t a useful simplification to many modern psychiatrists—it’s just how depression is.
This is what Kuhn meant by incommensurability. Paradigms aren’t just different theories. They’re different worlds. You can’t fully translate between them because they carve up reality at different joints.
Why Smart People Defend Dead Ideas
One of Thomas Kuhn’s most unsettling observations: paradigm shifts don’t happen because everyone examines the evidence and rationally updates their beliefs. They happen because the old guard literally dies off.
Max Planck, one of the founders of quantum mechanics, put it bluntly: “Science advances one funeral at a time.”
This seems absurd. Aren’t scientists supposed to follow evidence wherever it leads? Aren’t they trained to overcome bias?
Yes, but they’re also trained into a paradigm. Your PhD isn’t just an education—it’s an initiation. You learn not just facts but what questions are worth asking, what methods are legitimate, what kind of explanations count as satisfying. You learn to see the world the way your field sees it.
And then your entire career depends on that paradigm being correct. Your grants, your publications, your reputation, your sense of being competent—all of it is built on a particular way of carving up reality. When a paradigm shift comes along, it doesn’t just challenge your ideas. It threatens to make your life’s work irrelevant.
So of course you defend the old paradigm. Not because you’re dishonest or stupid, but because abandoning it means admitting that the sophisticated apparatus you’ve mastered—the techniques, the distinctions, the hard-won expertise—might be based on the wrong questions entirely.
The Tyranny of the Obvious
Here’s the really maddening part: your paradigm determines what counts as evidence in the first place.
Before germ theory, doctors could watch patients die after surgery and see nothing wrong with their technique. The idea that invisible organisms were causing infections wasn’t just unproven—it was preposterous. Why would washing hands matter? The wounds weren’t dirty in any visible sense.
Ignaz Semmelweis gathered data showing that handwashing dramatically reduced maternal mortality. His colleagues saw the same data and concluded… nothing. It didn’t fit their paradigm, so it didn’t register as meaningful. Semmelweis died in an asylum, his discovery rejected.
Within a generation, germ theory was obvious. The same data that meant nothing suddenly meant everything. Not because the data changed, but because the paradigm did.
This happens constantly, in every field. Economists can look at the same employment statistics and see completely different stories about what’s happening, because they’re operating within different paradigms about how economies function. Psychologists can observe the same behavior and classify it as healthy adaptation or pathological dysfunction depending on their theoretical framework.
You’re not seeing evidence and then forming a worldview. Your worldview is determining what counts as evidence.
The Paradigms You Didn’t Choose
The uncomfortable truth is that most of your paradigm wasn’t chosen by you. It was inherited.
You didn’t decide that depression is best understood as a chemical imbalance rather than a spiritual malady or a rational response to an irrational world. You absorbed that from your culture. You didn’t choose to think of success in terms of career achievement rather than spiritual enlightenment or family legacy. Your historical moment chose that for you.
Even your sense of what questions are interesting, what problems are important, what explanations are satisfying—all of this was shaped by forces mostly invisible to you.
Consider the idea of “human rights.” To a modern Western audience, this seems self-evident. Of course humans have inherent dignity and autonomy. But this is a very specific cultural paradigm, one that would have seemed bizarre to most humans throughout history. Ancient Romans, medieval Chinese scholars, or pre-Columbian Aztecs operated within entirely different frameworks for understanding human value and social organization.
They weren’t wrong and we’re not right (or vice versa). We’re all operating within paradigms that make certain ways of organizing society visible and others unthinkable.
Can You Escape Your Prison?
Here’s where it gets tricky. If your paradigm determines what you can see, how can you ever see past it?
Kuhn’s answer was basically: you can’t, not really. You can’t step outside all paradigms and see reality as it truly is, free from interpretation. That’s not how human knowledge works. We’re always inside some framework.
But you can become aware that you’re in a framework, not the framework. You can learn to hold your beliefs more lightly. You can notice when you’re dismissing evidence because it doesn’t fit your paradigm rather than because it’s actually wrong.
The trick is to actively seek out people operating within different paradigms. Not to prove them wrong, but to understand how the world looks from inside their framework. What questions are they asking? What seems obvious to them that seems bizarre to you? What are they able to see that you’re blind to?
This is harder than it sounds. Your instinct will be to translate their views into your paradigm and then show why they’re mistaken. “Oh, they believe X, which is clearly wrong because of Y”—where Y is something that only makes sense within your paradigm.
Real paradigm-hopping requires imaginatively inhabiting a different way of seeing. It means taking seriously the possibility that smart, informed people who disagree with you aren’t just wrong—they might be seeing something you can’t.
The Useful Paranoia
Kuhn’s ideas can sound like an argument for relativism. If we’re all trapped in paradigms, doesn’t that mean all views are equally valid? Isn’t truth just whatever your paradigm says it is?
No, and this is crucial. Paradigms aren’t arbitrary. They succeed or fail based on how well they help us navigate reality. Newton’s physics worked brilliantly for centuries because it accurately predicted how medium-sized objects behave at medium speeds. It only broke down at extremes—very large, very small, very fast—which is exactly when Einstein’s paradigm becomes necessary.
The point isn’t that truth is relative. It’s that truth is paradigm-dependent. Within a given framework, some statements are definitely true and others are definitely false. But different paradigms might carve up reality in ways that make your true/false distinctions meaningless.
This should make you intellectually humble, but not paralyzed. Yes, you’re operating within a paradigm you can’t fully see out of. But so is everyone else. The best you can do is:
- Stay curious about anomalies—things your paradigm struggles to explain.
- Listen to people who see the world differently without immediately arguing.
- Hold your certainties loosely enough that you could abandon them if something better comes along.
- Remember that some of your most obvious beliefs would seem insane to people from other times and places.
Living in the Prison
The irony is that you need a paradigm. You can’t function without one. Trying to see reality without any interpretive framework isn’t enlightenment—it’s psychosis.
Your paradigm is a tool. Like any tool, it’s good for some jobs and terrible for others. A hammer is perfect for nails and useless for screws. Your paradigm reveals certain truths and obscures others.
The goal isn’t to escape all paradigms. It’s to remember you’re using one. To treat your worldview as a map rather than the territory. To remain teachable.
Because eventually, your paradigm will encounter something it can’t explain. Some anomaly that doesn’t fit. And at that moment, you’ll have a choice: defend your framework by dismissing the anomaly, or stay curious about what you might not be seeing.
The people who make the latter choice—who remain open to the possibility that their most fundamental assumptions might be wrong—those are the ones who occasionally glimpse the bars of their cage.
They’re still prisoners. We all are. But at least they know it.
And that changes everything.
