This piece is inspired by Jo Marchant’s March 16, 2026 article discussing QBism, Wheeler’s delayed-choice ideas, predictive processing, and enactivism. The core claim in that article is not settled physics, but a live interpretive proposal: quantum states as agent-centered expectations rather than observer-independent properties, perception as model-building, and reality as something more like interlocking perspectives than a single God’s-eye block. QBism is a real interpretation of quantum mechanics, and its key move is to treat quantum probabilities as personal Bayesian degrees of belief; predictive processing similarly treats perception as the brain’s best ongoing model of the world.
The Shared World
Song — We Make the World Together
Naomi was irritated before she knew why.
Daniel had moved the chair again.
Not far. Just enough that when she came into the room with a cup of tea, the familiar path her body expected was no longer there. Her shin clipped the leg, the tea sloshed, and a hot thread of annoyance shot up her chest.
“Why do you always move things?” she snapped.
Daniel looked up, surprised. “I moved it so the light would hit the plant.”
For half a second Naomi felt the familiar righteousness assemble itself.
Of course. His way. His preference. His rearranging of the world.
But then something loosened.
Not because she became spiritual.
Because she noticed.
Her body had already built a room before she entered it.
A predicted room.
A remembered room.
A room with chair-there and path-here and cup-safe and body-moving-smoothly.
Daniel had built a different room.
A room with the plant getting light.
A room with better angles.
A room shaped by his eye, not hers.
Two rooms.
One apartment.
And suddenly her irritation looked less like “he did something wrong” and more like “my world and his world just collided.”
She stood still.
Tea dripping faintly onto her hand.
Heat in the chest.
Thoughts ready to prosecute.
But under all of that was something simpler:
No one had access to the room “as it really was.”
There was only:
her lived version
his lived version
and now this moment of contact where they had to negotiate something shared
Daniel was still watching her.
She laughed unexpectedly.
“What?” he said.
“I think I just ran into my own reality,” she said.
He smiled. “Mine too.”
And there it was.
Not agreement.
Not objectivity.
Not two private bubbles either.
Something more alive than that.
The world between them was being made, not found.
Not from nothing — the chair was there, the plant was there, the tea was definitely hot — but the meaning, the relevance, the shape of the moment was emerging through contact.
Naomi put the cup down.
“Okay,” she said. “Let’s find a place where the plant gets light and I don’t injure myself.”
Daniel nodded.
And in that tiny domestic negotiation, something felt absurdly profound.
Reality wasn’t a fixed stage they had walked onto.
It was more like jazz.
A pattern emerging from interlocking moves.
Not “my world” or “your world.”
A shared world, constantly under construction.
Investigation — From “My Reality” to “Our Contact”
The article you shared points toward a radical but useful shift: from imagining one fully objective reality “out there” to noticing that lived reality is always shaped through perspective, action, prediction, and interaction. QBism, as described by Christopher Fuchs and colleagues, treats quantum probabilities as agent-centered beliefs rather than objective properties, and the article connects that with predictive processing and enactivism: perception as model-building, organisms as co-creating their worlds through action.
For your inquiry work, this can be translated into very plain language:
1. You never meet “the world” raw
You meet:
sensation
perception
interpretation
relevance
action tendency
Even before thought, the nervous system is already selecting, filtering, predicting. Predictive processing explicitly frames perception as the brain’s best current guess, updated by incoming signals.
2. That does not mean “it’s all in your head”
This is where people get lost.
The stronger versions of QBism and enactivism are not simply saying “nothing is real.” They are saying that what becomes real for an agent is inseparable from interaction, question, action, and consequence. There are still constraints. In QBism, the Born rule remains a normative constraint that ties expectations together; it is not just free-floating fantasy.
Translated into direct experience:
You can’t just decide the chair isn’t there.
You can’t decide boiling water is cool.
But what the chair means, what matters about it, how it enters your lived world — that emerges in relationship.
3. The practical human version: worlds collide all day
Most conflict is not “truth versus error.”
Often it is:
my predicted world
meeting your predicted world
Examples:
I hear “criticism,” you hear “clarity”
I feel “distance,” you feel “space”
I see “chaos,” you see “freedom”
The old move is:
One of us must be wrong.
The more interesting move is:
What worlds are meeting here?
4. A direct-experience practice
Next time friction appears, pause and ask:
What happened in raw experience?
What did my system immediately make it mean?
What world did I assume we were both standing in?
What if the other person’s world is configured differently?
Do not use this to gaslight yourself.
If something hurts, it hurts.
But often the charge softens when you see that “reality” in the moment includes:
the event
your bodily response
your interpretation
their interpretation
the contact between them
5. The non-dual edge
Taken deeply, this lands in familiar territory for your work:
There is no isolated observer standing outside experience.
There is only participating.
Not a separate self looking at a finished universe.
Just this ongoing meeting — sensation, action, response, consequence.
That is why “now” matters so much in the article. Not because it proves metaphysics, but because it restores the sense that experience is not a dead block already finished. It is alive in contact.
6. The clean pointer
Forget “Do we create reality?” for a minute.
Look closer:
How much of your suffering comes from assuming your interpretation is the world itself?
That one question is already enough.
