Your intuition about consciousness being separate from your brain is probably wrong.
And the reason isn’t that consciousness is some mysterious, ethereal force.
It’s that your brain has evolved to trick you into believing exactly that.
Recent research from Northeastern University psychology professor Iris Berent reveals something startling about how ordinary people perceive consciousness.
We don’t consistently view consciousness as either physical or non-physical.
Instead, our perceptions flip-flop depending entirely on the context of the question.
In a groundbreaking study published in Neuroscience of Consciousness, Berent demonstrates that the famous “hard problem of consciousness” isn’t actually hard because consciousness is mysterious.
It’s hard because of deeply embedded psychological biases that distort how we think about minds and bodies.
The Zombie Test and the Color Scientist
Berent’s research centers on two classic thought experiments that philosophers have debated for decades.
The first involves imagining your “zombie twin,” a creature with your exact physical features but without thoughts or feelings.
When asked about this scenario, people consistently say consciousness must be separate from the physical body.
After all, if a perfect physical replica can exist without consciousness, then consciousness can’t be physical, right?
The second experiment involves Mary, a neuroscientist who knows everything about color and how the brain processes it, but has lived her entire life in a black and white room.
When Mary finally sees a red rose, people agree she learns something transformative.
But here’s where it gets interesting.
When Berent asked participants whether this transformative experience would show up in Mary’s brain, they overwhelmingly said yes.
It would light up on a brain scan.
In other words, people said consciousness is physical in Mary’s case but not physical in the zombie case.
The same people, thinking about consciousness, gave completely contradictory answers.
The Pattern Nobody Expected
Here’s what most researchers get wrong about consciousness.
They assume that when people say consciousness seems non-physical, they’re revealing something true about the nature of consciousness itself.
Philosophers and scientists have built entire careers arguing about whether consciousness really does transcend the physical world.
Influential thinker David Chalmers even won a bet in 2023 for claiming consciousness exists beyond the merely physical.
But Berent’s research shows this entire debate might be built on quicksand.
If people’s intuitions about consciousness change depending on how you ask the question, then these intuitions can’t possibly reflect what consciousness actually is.
They must reflect something about how our brains process information about minds and bodies.
“If people change their mind in this way, it can’t possibly be that in reality consciousness has changed,” Berent explains in an interview with Northeastern University.
“It must be that there is something within the human psyche that colors how we see consciousness.”
Two Ancient Biases Colliding
The explanation for this contradiction lies in two powerful psychological biases that shaped human evolution.
The first is intuitive dualism, the automatic tendency to perceive minds as ethereal and separate from bodies.
This bias appears in young children across cultures.
When you ask kids what happens after someone dies, they’ll tell you the body stops working but the person’s thoughts and knowledge continue.
Research shows this dualist thinking served an evolutionary purpose.
Our ancestors needed to distinguish between living agents (like mothers who could provide care) and inanimate objects (like rocks that couldn’t).
Being able to track minds separately from bodies meant knowing which entities had agency, which could help you or harm you.
The second bias is intuitive essentialism, the belief that living things possess an innate essence that lies within their physical bodies.
This is why people think your DNA contains the “real you” and why transformative experiences feel like they physically change who you are at your core.
When these two biases interact, they create the contradictory intuitions Berent documented.
Why Zombies Feel Different Than Scientists
The zombie scenario activates intuitive dualism strongly because it explicitly compares a mind to a body.
You’re asked to imagine a creature with your physical form but without mental states.
This framing naturally highlights the separation between mental and physical, making consciousness seem ethereal.
The Mary scenario works differently.
You’re not comparing mind and body as separate categories.
Instead, you’re evaluating a change to a single person, Mary herself, before and after her experience.
This shifts attention to her body and brings intuitive essentialism to the forefront.
Seeing color feels transformative precisely because it seems anchored in a physical organ: the eyes.
The experience feels like it changes Mary’s essence, and essence lives in the body.
Therefore, the experience must register physically in her brain.
The key insight: both answers can’t be right, which means both are being shaped by cognitive biases rather than reflecting truth about consciousness.
The Real-World Consequences
This research matters far beyond philosophical debates.
These psychological biases shape how people understand mental health, neuroscience, and their own minds.
When people learn that depression has a physical basis in the brain, it can actually increase stigma rather than reduce it.
Why?
Because if intuitive essentialism tells you that what’s in your body is innate and immutable, then learning depression is physical makes it seem like a permanent, unchangeable flaw in your essence.
The biases also affect how people react to neuroscience findings.
When research shows that learning physically changes the brain, people express surprise, as if there were some alternative.
But where else could learning be happening if not in the brain?
The shock reveals the hidden influence of dualist thinking.
Research by Berent and colleagues shows these biases aren’t uniform across all people.
Autistic individuals tend to be less dualistic than neurotypical people.
Males show weaker dualist intuitions than females on average.
These differences suggest the biases aren’t simply hardwired but can vary in strength.
What Brain Activity Actually Tells Us
Modern neuroscience increasingly supports the view that consciousness is indeed a physical process.
Recent advances in consciousness research have identified specific neural signatures associated with conscious awareness.
Scientists can now predict whether someone is conscious based on patterns of brain activity.
They can distinguish between different levels of awareness in patients with disorders of consciousness.
The field has moved from asking whether consciousness has physical correlates to mapping exactly which brain processes give rise to which aspects of subjective experience.
Theories like Integrated Information Theory and Global Workspace Theory propose specific mechanisms by which neural activity produces consciousness.
These theories make testable predictions that researchers are actively investigating.
The scientific consensus, backed by decades of neuroimaging and neurophysiological studies, points strongly toward consciousness being a brain-based phenomenon.
What feels mysterious about consciousness, according to Berent, isn’t a genuine ontological puzzle but rather a psychological puzzle about why our intuitions mislead us.
Rethinking the Hard Problem
Philosopher David Chalmers famously coined the term “hard problem of consciousness” to describe the challenge of explaining how physical processes give rise to subjective experience.
Why does seeing red feel like something?
How does electrochemical activity in neurons become the vivid sensation of tasting coffee or the sharp pain of a pinprick?
Berent’s research suggests the “hard problem” is hard for the wrong reasons.
It’s not that consciousness is genuinely mysterious or irreducible to physical processes.
It’s that human psychology makes it feel that way.
We evolved cognitive biases that helped our ancestors survive, and those same biases now interfere with our ability to think clearly about consciousness.
The research published in Open Mind shows that when you ask people whether transformative experiences change the brain, the more “embodied” the experience seems, the more transformative people rate it.
Experiences clearly tied to sensory organs, like seeing color, seem more transformative than abstract knowledge.
This pattern directly contradicts what we’d expect if people genuinely viewed consciousness as non-physical.
If consciousness were truly separate from the body, then experiences shouldn’t seem more transformative just because they involve physical sense organs.
The Illusion at Work
Think of it this way: your perception of consciousness is like a magic trick your brain plays on itself.
The illusion is so convincing that even when you understand how it works, you can’t stop experiencing it.
You still feel like your thoughts exist separately from your physical brain.
You still intuit that there’s something mysterious about subjective experience.
But now you know that feeling is generated by the same psychological machinery that once helped your ancestors distinguish friend from foe, living from dead.
Berent calls these “delusional attitudes about bodies and minds,” but the delusion serves a purpose.
Intuitive dualism and essentialism helped humans navigate a complex social world where understanding agency, identity, and personhood mattered for survival.
The problem arises only when we try to use these intuitions as evidence in philosophical or scientific debates about consciousness.
As Berent notes in commentary on her research, both “illusionists” (who argue consciousness might not even exist as we conceive it) and “realists” (who take consciousness at face value) agree that people perceive consciousness as non-physical.
Her research challenges this shared assumption.
People don’t consistently perceive consciousness as non-physical at all.
Their perceptions shift with context in ways that reveal the operation of underlying biases.
A New Framework for Understanding Minds
The implications extend beyond consciousness to how we think about human nature more broadly.
If our intuitions about consciousness can’t be trusted, what else might our intuitions mislead us about?
Berent’s broader research program investigates how people reason about psychological traits, inheritance, and identity.
The same biases that shape consciousness intuitions affect judgments about personality, intelligence, mental illness, and what makes someone “who they are.”
For scientists studying consciousness, the lesson is clear: be skeptical of intuitions.
Don’t assume that because something feels obvious or mysterious, it reflects reality.
Test your assumptions empirically.
Recognize that you’re not immune to the same psychological biases that affect everyone else.
For everyone else, the research offers a kind of cognitive freedom.
You don’t have to trust your intuitions about consciousness being separate from your brain.
You can recognize that feeling for what it is: an artifact of how your mind evolved to categorize the world.
Consciousness almost certainly comes down to electrochemical functions in the brain, as Berent suggests.
The mystery isn’t in consciousness itself but in understanding why our psychology makes it seem so mysterious.
Where This Leaves Us
The debate about consciousness won’t end with this research.
Philosophers will continue arguing about qualia and zombies and whether physical explanations can ever fully capture subjective experience.
Scientists will keep mapping neural correlates and testing theories about how brain activity generates awareness.
But Berent’s work introduces a crucial variable that previous discussions often ignored: the psychology of the people having these debates.
When we argue about consciousness, we’re not purely rational agents dispassionately evaluating evidence.
We’re humans with evolutionary baggage, cognitive biases, and minds that actively distort our perceptions of minds.
Understanding this doesn’t make consciousness any less real or important.
Your subjective experiences remain as vivid and meaningful as ever.
But it does suggest that the path to understanding consciousness runs not just through neuroscience and philosophy but through psychology as well.
We need to understand not just what consciousness is, but why we think about it the way we do.
The next time you find yourself wondering whether your mind could exist without your brain, remember: your intuition has an agenda.
It’s not showing you reality.
It’s showing you what your ancestors needed to believe in order to survive.
The real question isn’t whether consciousness transcends the physical.
It’s whether we can transcend our intuitions long enough to see what consciousness actually is.
