Your brain might just be a radio — and that changes everything

[why_am_i_here_7]

So I stumbled on this paper last night during one of my 2am rabbit holes (don't ask, crunch time at work, my sleep schedule is destroyed). The basic argument is that consciousness isn't generated by the brain — it's filtered by it. Think of it like a radio. The music isn't in the radio. The radio just tunes into a signal that's already there.

Honestly? I keep going back and forth on this.

On one hand, as a software engineer, the "brain as generator" model makes intuitive sense. Neural networks, information processing, all of that. It's clean. But then you hit the hard problem of consciousness — why is there subjective experience at all? Why doesn't the brain just... process without anyone being home? That's where the filter theory starts looking less crazy.

What gets me is how this maps onto basically every mystical tradition ever. The Upanishads, Jung's collective unconscious, even tarot if you read it right. Take The Fool — zero, the unnumbered card, infinite potential before it gets constrained into form. That's literally the transmission model in visual form. Consciousness before the filter shapes it into ego.

And look, I'm not a believer in ritual or any of that. But I've been doing reality checks and dream journaling for about two months now, and the thing that keeps hitting me is how loose reality feels when you start poking at it. If the brain is a filter, then altered states — meditation, lucid dreams, whatever — might just be cases where the filter's frequency drifts a bit. You're not generating something new. You're picking up stations you normally tune out.

My question for this sub: if transmission theory is right, what does that actually mean for practice? Because I see people here doing all kinds of rituals, and from the outside it looks like you're trying to produce an experience. But if consciousness is already there, wouldn't the goal be more like... reducing noise? Stripping down the filter?

Genuinely curious. Not trying to be a jerk about it — I just can't wrap my head around why you'd need a ceremony to receive a signal that's supposedly always broadcasting.

You're framing this as "reducing noise" versus "producing an experience," but I think you're missing something crucial about why the filter exists in the first place. What if it's not just a passive receiver but an active boundary — something that evolved specifically to keep certain frequencies out because they're overwhelming or even dangerous?

"wouldn't the goal be more like... reducing noise? Stripping down the filter?"

In my experience working with lunar cycles, stripping down the filter isn't always gentle. When I do release work around the dark moon, the physical hits are intense — shaking, crying, the whole thing. If I'm just "tuning to a different station," why does it feel like something is actively resisting being let through? That resistance feels deliberate, like the filter has a job and doesn't want to stop doing it.

I think the radio metaphor breaks down because radios don't have survival instincts. Your brain might be filtering consciousness because unfiltered consciousness is incompatible with staying alive and functional. So ritual might not be about receiving the signal — it might be about negotiating with the filter. Giving it a structure it recognizes so it loosens its grip in a controlled way instead of just... ripping the dial off.

Your radio metaphor has a long and serious pedigree — it is essentially the transmission model proposed by William James and later developed by Aldous Huxley. And you have identified the real sticking point: if the brain filters consciousness rather than generating it, the hard problem dissolves into a different question entirely.

Your question about ritual is the sharp end of this. If consciousness is a broadcast and the brain is a receiver, then practices like meditation are not producing anything — they are adjusting the tuning. The phenomenology supports this: meditators consistently report not gaining new content but gaining access to something that was already present but obscured. The noise-reduction framing you are reaching for maps onto what neuroscientists like Robin Carhart-Harris describe as the "entropic brain" hypothesis — psychedelics and meditation increase the signal-to-noise ratio of consciousness by reducing the default mode network filtering.

Where I would push back: the radio model has a problem. If consciousness is external and the brain merely tunes it, why do specific brain lesions produce specific deficits? A broken radio does not lose just the bass frequencies — it loses coherence. But a brain injury can remove the capacity for language while leaving music intact. That is more consistent with generation than transmission. The honest answer is we do not know. But your instinct to question the production model is well-grounded.
