When the Self Dissolves, the Precuneus Goes Quiet: A Rigorous Test of Meditation’s “Many-to-(n)One” Continuum

 A recurring question on this blog is how much of what we take to be fixed about experience—time, space, agency, the bounded self—is actually a construction the brain assembles from past experience and could, in principle, take apart. Laukkonen and Slagter’s 2021 paper “From many to (n)one: Meditation and the plasticity of the predictive mind” gave that question its most ambitious recent framing. Their proposal is elegant in its simplicity: the three meditation styles most studied in contemplative science—focused attention (FA), open monitoring (OM), and non-dual awareness (ND)—are not separate practices but points on a single continuum. Each one, in turn, relinquishes a more deeply engrained habit of prediction, bringing the practitioner closer to the here-and-now and progressively flattening the predictive hierarchy until even the sense of self falls away. Meditation, in their metaphor, “prunes the counterfactual tree.”

It is a beautiful theory. The harder question is whether the brain imaging literature actually supports it, or whether the data have been arranged to fit a staircase that was drawn in advance. I want to use one study to think this through, because it is the rare case where the methodology is strong enough to bear the interpretive weight: a 2024 preregistered MEG study from Trautwein, Schweitzer, Dor-Ziderman, Berkovich-Ohana and colleagues, published in the Journal of Neuroscience, titled “Suspending the Embodied Self in Meditation Attenuates Beta Oscillations in the Posterior Medial Cortex” (Trautwein et al., 2024).

What the older evidence looked like

First, the backdrop. At the coarse level, the imaging literature does rhyme with the continuum. Focused attention is the best-characterized rung: meta-analysis associates it with activation in attentional-control machinery—dorsolateral prefrontal cortex, dorsal anterior cingulate, insula—and with deactivation of the default mode network, the system tied to self-referential thought and mind-wandering (Fox et al., 2016). That DMN quieting is exactly what the framework needs to claim FA pulls one out of the “narrative self.” Open monitoring shifts the picture toward more distributed, less object-bound dynamics and reduced coupling within posterior default-mode regions. And the non-dual end—self-dissolution—had been linked, in a series of small studies, to attenuation of beta-band activity in right parietal cortex and to reductions in the precuneus (Dor-Ziderman et al., 2013; Josipovic, 2014).

The problem is that the non-dual evidence, which is where the theory makes its most startling claims, rested on the thinnest foundation. The canonical neurophenomenological studies in this lineage ran on twelve subjects (Dor-Ziderman et al., 2013). They typically used rest as the comparison condition—a notoriously leaky baseline, since long-term meditators’ resting brains already drift toward meditative configurations. And the interpretive leap from “beta drops in the parietal cortex” to “the self-model has dissolved” is the reverse-inference trap in its purest form: those regions and rhythms do many things. This is the kind of literature the fifteen-author “Mind the Hype” consensus paper had in mind when it warned that small samples, flexible analysis, and post-hoc storytelling in contemplative neuroscience could mislead the public and the field alike (Van Dam et al., 2018).

So the right question is not “does some imaging study support the continuum”—several do, loosely—but “does any study support it under conditions rigorous enough that we should believe the correlation means what it is claimed to mean.” That is what makes the 2024 paper worth dwelling on.

A study built to fail honestly

The design corrects, one by one, the weaknesses of the work that preceded it. Forty-six long-term meditators (mean lifetime practice around 3,800 hours) were trained to volitionally modulate their embodied self-experience inside an MEG scanner (Trautwein et al., 2024). Hypotheses and the analysis plan were preregistered, and the researchers were blinded to the experimental condition during preprocessing—two practices that close off the garden of forking paths where false positives flourish.

Most importantly, the study did not rely on a rest baseline alone. It used an active control: meditators alternated between dissolving their sense of self-boundaries (the condition of interest) and maintaining a clear sense of self-boundaries while meditating just as hard. This is the crucial move. A meditation-versus-rest contrast differs in dozens of ways beyond the phenomenology you care about. A dissolution-versus-maintenance contrast, within the same person in the same posture doing the same kind of effortful practice, isolates the self-boundary variable itself.

And then they did something I find methodologically beautiful. Rather than validating the meditative state with a checkbox questionnaire, they ran detailed microphenomenological interviews after the scan and used them to define, in advance of looking at the brain data, a subgroup of “full dissolvers”—participants who reported the most complete suspension of agency, first-person perspective, and self-location.

What they found

The headline result confirms the framework’s boldest prediction. When dissolution states were contrasted with the active control, power dropped specifically in the high-beta band, source-localized to the posterior medial cortex—the posterior cingulate and precuneus—and to lateral parietal regions. The peak frequency was 27 Hz, replicating an earlier single-case study to the hertz.

The effect was graded in a way that genuinely echoes the continuum. Broader reductions in somatomotor and dorsal parietal regions appeared even at lower levels of dissolution across the whole sample, whereas the posterior-cingulate/precuneus reductions distinguished only the full dissolvers. This is a real neural gradient tracking increasingly basal dismantling of the self—just what “unraveling increasingly basal forms of selfhood” would predict. And the effects scaled with both lifetime hours of meditation and, within the dissolution experience, with the reported loss of first-person perspective and self-location. The brain change tracked the depth of the experience, not merely the instruction to have it.

The authors themselves reach for predictive processing to explain it. They speculate that the beta reductions reflect the suspension of body- and agency-related predictions, leaning on models in which beta-band oscillations carry top-down predictions and precision estimates that modulate the bottom-up signaling of prediction errors. In other words, the convergence between this data and the Friston-style account is not something Laukkonen and Slagter imposed from outside. The experimentalists arrive at the same place.

The finding that should unsettle the field

Here is the result I keep returning to. The neural changes correlated with the interview-derived experiential measures—but not with the classical self-report instruments. The widely used five-dimensional altered-states questionnaire produced an “oceanic boundlessness” score that did not correlate at all with the phenomenological summary derived from the interviews (r = 0.06). The deep first-person interview and the standard psychometric checkbox were, in effect, measuring different things, and only the former tracked the brain.

Sit with what that implies retroactively. A large fraction of the prior imaging literature validated its meditative “states” precisely with the kind of thin, questionnaire-based measure that here failed to predict the neural signature at all. If the checkbox doesn’t track the brain, then studies that used the checkbox to certify that their subjects were “in” the non-dual state may have been correlating brain activity with a label rather than with the experience the label names. The 2024 study’s strongest contribution may be less the precuneus finding than this quiet demonstration that phenomenological rigor is not optional decoration—it is load-bearing.

Where this leaves the continuum

So does brain imaging confirm the many-to-(n)one model? My honest reading is: partially, gradedly, and only under conditions most of the supporting literature did not meet.

The reservations remain real. The studies that compare FA, OM, and ND almost always do so within expert meditators who already hold the three-category taxonomy as their own theory of their practice—so the taxonomy is an input as much as an output, and “the brain states differ” does not establish “the brain states lie on a single monotonic dimension.” The most comprehensive meta-analysis found the practices reliably dissociable but found convergence across them to be the exception rather than the rule, and offered only suggestive evidence for the non-dual category specifically (Fox et al., 2016). Effect sizes across the field are medium, not large, with substantial heterogeneity. The scanner environment itself—noise, supine posture—has been shown to shallow and distort the very states under study. And the framework absorbs apparently disconfirming results (Pagnoni’s reading of just-sitting Zen as increasing counterfactual richness, for instance) by partitioning state from trait, a plausible move that also makes the theory harder to falsify.

But against all that, the 2024 study stands as something the older work was not: a preregistered, blinded, actively-controlled, phenomenologically-anchored demonstration that the most radical claim in the whole framework—that advanced practice can dismantle the embodied self—corresponds to a specific, replicable, dose-dependent neural signature, read by its own authors in predictive-processing terms (Trautwein et al., 2024). The staircase metaphor still outruns the data. The top step, at least, now has a floor under it.

A closing thought

What draws me to this, beyond the meditation question, is what it says about the self as such. The deepest premise shared by the predictive-processing account and this experiment is that the sense of being a bounded, located, agentic first person is not a given but a construction—a model the brain maintains through ongoing prediction, and one that can be set down and, evidently, picked back up. If the self is a modulable predictive construct rather than a fixed seat of agency, then questions about what happens to authorship and agency when we offload regulation—onto a practice, onto a tool, onto an AI machine—become questions about how plastic that construct really is, and at what cost it bends. A meditator dissolving the precuneus’s beta rhythm and a person feeling like a diminished author of their own actions may be probing the same machinery from opposite directions.

The polyvagal theory is dead - and HRV isn't a simple indicator of arousal

I was recently struck by Baxter's Substack post (its title copied to be the title of this MindBlog post), which noted work critical of Porges' Polyvagal  theory (or PVT) published iin the journal Clinical Neuropsychiatry, because it calls into question one idea commonly derived from this theory that I have accepted (and repeated in several MindBlog posts): that heart rate variability can be taken as a simple indicator of calm (higher HRV and parasympathetic nervous activity) versus arousal (lower HRV and sympathetic nervous system activity).  A number of bio-monitors such as the Apple Watch and the Oura Ring report ongoing HRV measurements.  Here is a clip from her article, and then the abstract of the multi-author paper she references.

Psychological safety, social engagement, co-regulation, emotional freezing, dissociation — these are real phenomena, supported by decades of research that predate PVT. They come from attachment theory, trauma research, and somatic practices. The (critical paper’s authors explicitly state that body-mind therapeutic methods “may confer benefits on their own.”

So the work stands.

What doesn’t is the specific neuroanatomical story Porges constructed to explain these states, i.e. what drives them. This is the now-familiar three-tier hierarchy: dorsal vagal shutdown, ventral vagal social engagement, sympathetic activation.

Porges got the clinical observations right—or rather, he built upon clinical observations that were already well-established. But the mechanism is wrong.

Concerningly, Porges continued to assert that mechanism for thirty years, even as the evidence mounted against it, and apparently misrepresenting and distorting the work of other scientists to support his claims. Rather than engage with criticism of his theory, Porges ignored the overwhelming scientific consensus and instead promoted this inaccurate framework as sound, misleading practitioners and clients alike.

There is good news in all this mess—for clinicians at least. What you observe in your clients is real. Hyper-arousal is real. The need for safety and co-regulation is real. People really do dissociate, numb, and freeze when overwhelmed. Your interventions still work. They just don’t work for the reasons PVT said they did.

 *********

Here is the Grossman (+38 co-authors) summary:

This article specifically appraises--based upon the current state of knowledge of autonomic function and vertebrate evolution--several major elements of the PVT, as described in Porges (2025a) and elsewhere. These include: 1) the validity of PVT assumptions that respiratory sinus arrhythmia is a direct measure of the extent of central vagal drive to the heart; 2) PVT characterizations regarding the neuroanatomy and functions of two major brainstem vagal nuclei, the ventrally situated Nucleus Ambiguus and the Dorsal Motor Nucleus of the vagus nerve; 3) PVT assertions regarding the evolution of the vagus nerve; 4) PVT claims about the specificity of mammalian social behavior in relation to nonmammalian vertebrates, and 5) PVT interpretations of earlier seminal physiological literature. All co-authors agree that major tenets of the PVT are not supported by past or current knowledge and, in several instances, are inconsistent with the broader evidence base. Since the topics addressed constitute fundamental premises of the PVT, we conclude that the PVT is untenable, because it is not defensible based on existing neurophysiological and evolutionary evidence. The psychological elements composing the superstructure of the PVT are primarily derived from earlier psychological literature and are neither clarified nor strengthened by PVT constructs that lack evidence. This article does not intend to address alternative explanations about relations between vagal function and psychological processes, although such explanations do exist. 

The text of this article is mind-numbingly detailed and complex, as is a rebuttal of the critique by Porges in the same issue of Clinical Neuropsychiatry.

I am not my problem

I use this MindBlog to go back and look myself up occasionally, and so pass on this re-post of my 10/26/2025 post:

An explanation of the strange title of this post: Sometimes a new idea spontaneously appears from nowhere as I am waking in the morning. The title of this post - the (apparently nonsensical) sentence "I am not my problem” - is the latest example. The sentence can to be parsed to indicate in this instance that the "I" is referring to the illusory narrative self that our social brains have been designed by evolution to generate, and the "my" refers to our intuition or sensing of the vastly complex underlying interacting body systems (respiratory, circulatory, neuronal, muscular, endocrine, sensory, etc.) from which this veneer of a self rises. The brain is mainly not for thinking. It appears that several styles of meditation practice can expand our awareness of this fundamental generative layer. The "am not my problem" tries to make the point that distinguishing these systems can prove useful in trying to determine the origins of particular feelings or behaviors. 

As I’m writing these words I begin to realize that my “novel” waking insight isn’t so novel, but more an elaboration or restatement of my post of Friday, March 13, 2020, on “the relief of not being yourself,” which described another spontaneous rising of ideas associated with the transition between sleep and wakefulness. I repeat that text here:

What a relief to know that this is not me, it is just the contents of my consciousness, which shift around all the time and are never the same twice. What has changed, after 45 years of doing an introspective personal journal, is that this sentence has become clear and true for me. It is a prying loose from the illusion of the sensing and executive “I”, self, the homunculus inside.
There is a particular feeling of renewal, starting over, in the first moments of the transition to seeing - rather than immersed in being - one of the contents of consciousness. Meditation practice can be seen as training the ability to inhabit this state for longer periods of time, to experience the self or I as co-equal with other contents of consciousness like seeing, hearing, feeling. It is having thoughts without a thinker, having a self without a self.
What is inside is the animal mirror of expanded consciousness, no longer locked into one or another of its contractions. This feels to me like a potentially irreversible quantum bump, a phase or state change in my ongoing awareness (perhaps a long term increase in my brain’s attentional mode activity alongside a decrease its default mode’s mind wandering?...also frontal suppression of amygdalar reactivity?)

Focused attention mindfulness meditation changes our cerebrospinal fluid dynamics

From Keating et al.  

Significance

Mindfulness meditation is widely recognized for its self-reported mental and physical health benefits, yet its effects on core physiological systems that support brain health remain incompletely understood. This study provides evidence that a focused attention (FA) style of mindfulness meditation can modulate cerebrospinal fluid (CSF) dynamics in humans. Using neuroimaging, we demonstrate that FA meditation reduces regurgitant CSF flow through the aqueduct, directionally opposite to patterns seen in aging and neurodegeneration; additionally, meditation-induced CSF changes near the skull base are similar to those reported during sleep, an enhancer of neurofluid circulation. Findings suggest that mindfulness may offer a nonpharmacological, waking model for augmenting neurofluid circulation and provide a potential physiological mechanism linking meditation to brain health.
Abstract
Neurofluids, including cerebrospinal fluid (CSF) and interstitial fluid, circulate through regulated central nervous system pathways to clear cerebral waste and support brain health, with elevated CSF flow hyperdynamicity and regurgitation through the cerebral aqueduct associating with aging and neurodegeneration. Sleep exerts state-dependent effects on neurofluid circulation, yet similar modulation during unique waking states, such as meditation, remains underexplored. Notably, mindfulness meditation shares several regulatory features with sleep, with core meditation practices representing distinct arousal states. We investigated whether the focused attention (FA) style of mindfulness meditation modulates neurofluid dynamics directionally opposite to aging and consistent with sleep. Using phase-contrast MRI, we assessed absolute CSF flow and velocity through the aqueduct, and using blood oxygenation level–dependent (BOLD) MRI, we assessed CSF fluctuations near the cervicomedullary junction together with total supratentorial gray matter fluctuations. Assessments were repeated in meditation-naïve adults during mind wandering (MW) without (n = 13; repeatability controls) and with (n = 14; breath controls) respiration rate modulation and in adept meditators (n = 23) during MW and FA meditation. No aqueduct CSF flow changes were observed in control groups. In meditators, aqueduct absolute CSF flow motion decreased from MW to FA meditation (4.60 ± 2.27 mL/min to 4.17 ± 2.10 mL/min, P = 0.005) owing to reduced regurgitant cranially directed CSF flow velocity. On BOLD, this paralleled increased low-frequency (0.0614 to 0.0887 Hz) CSF fluctuations (P = 0.0138), which were inversely correlated with gray matter fluctuations during FA meditation. Findings suggest that mindfulness meditation may represent a nonpharmacological, waking state capable of modulating neurofluid dynamics in a directionally similar manner to sleep and opposite to aging and neurodegeneration.

How nature nurtures

MindBlog has passed on a number of articles on how exposure to nature reduces stress (see a sample list below). Here is a further contribution from Sudimac et al., who show amygdala activity decreases as the result of a one-hour walk in nature:

Since living in cities is associated with an increased risk for mental disorders such as anxiety disorders, depression, and schizophrenia, it is essential to understand how exposure to urban and natural environments affects mental health and the brain. It has been shown that the amygdala is more activated during a stress task in urban compared to rural dwellers. However, no study so far has examined the causal effects of natural and urban environments on stress-related brain mechanisms. To address this question, we conducted an intervention study to investigate changes in stress-related brain regions as an effect of a one-hour walk in an urban (busy street) vs. natural environment (forest). Brain activation was measured in 63 healthy participants, before and after the walk, using a fearful faces task and a social stress task. Our findings reveal that amygdala activation decreases after the walk in nature, whereas it remains stable after the walk in an urban environment. These results suggest that going for a walk in nature can have salutogenic effects on stress-related brain regions, and consequently, it may act as a preventive measure against mental strain and potentially disease. Given rapidly increasing urbanization, the present results may influence urban planning to create more accessible green areas and to adapt urban environments in a way that will be beneficial for citizens’ mental health.

Chants across seven traditions share acoustic traits that enhance subjective relaxation

From Canessa-Pollard et al.

For over 5,000 y, chanting has been practiced across many Western and Eastern traditions. However, there is hardly any empirical research on 1) whether chants from across the globe share common acoustic properties, 2) whether these acoustic features make them distinct from other human vocalizations, and 3) the extent to which they may positively impact listeners’ well-being. Here, we collected 242 chants belonging to seven distinct traditions and associated with a wide range of language families, and compared them acoustically to a large corpus of song (n = 126) and speech (n = 616) samples from across 14 linguistic and 12 geographical regions. We show that, irrespective of language and geographical origin, chants share distinctive acoustic traits, namely relatively flat and slow-changing intonation and steady, unbroken voicing in a comfortable, rather low pitch range with a prevalence of mid-central vowels. Thus, chants are produced in a relaxed vocal tract configuration with minimal articulation. Additionally, playback experiments involving original chants (with a participant pool of 61 listeners), resynthesized chants (with 114 listeners), and fully synthetic chants (with 80 listeners) demonstrate that these acoustic characteristics enhance listeners’ perceived sensations of relaxation. Specifically, relatively flat and slow-changing intonation, combined with vowel production in a relatively relaxed vocal tract configuration, resulted in higher overall relaxation ratings. Together these results hint at a specific function of chants’ acoustic commonalities: the enhancement of well-being through relaxation.

Everything we experience comes from inside us

Everything we experience is coming from inside us - our illusion of having a self, our sense of agency. This includes attributing causal agency to others, as in 'they are making me do this,’ This 'error' allows individuals in a kinship group or tribe who share the same error to form an imaginary 'we' hive mind supporting unified action. The higher metacognitive stance is to participate when necessary in the group illusion while maintaining clarity on the fact that the actual agency is within oneself.

Tokens of Sanity

My latest edit of the instruction set I live by: 

 

TOKENS OF SANITY

 
-Being the calm space in which nothing can hurry 

--A animal awareness that is also human, but able to dissociate from the word cloud and emotional reactivities of self and other selves.

-A courteous guest in its own body, and with the bodies of others, owning its own experience and letting them own theirs.

-Favoring reflectivity over reactivity, caressing novelty 

-Clinging to nothing, the current self being a passing wraith

-A blip in the flow of cosmic time

Deric and DeepSeek R1 on the enteroceptive self in a small world - taking refuge in troubled times

This post on an exchange with DeepSeek R1 is a followup on my previous post describing the Chat GPT 4o response to some of my idea fragments - further convincing me that current LLMs'  power to integrate and expand on concepts expressed in language are superior to mine.   

I presented exactly the same prompt to DeepSeek R1 that I had given to ChatGPT 4o: and the results astound me:

prompt:   

I’m curious to see how you might respond to reading the following notes on testing different topic ideas to write about and develop.  The issue is not one of whether the ideas are novel, but whether I might devise, with your help,  a different permutation, perspective, or take on them that I (and others) might find useful.  Can you can suggest some elaboration or further development of the ideas I put forward.

Here are the notes:

First Possible Title:  The interoceptive self as a basis for actions, thoughts and feelings.  

Subtitle: Moving the self’s experienced center of gravity from “I” to “it”

It is a question of who and/or what is running the show

Which brings it back to the old upstairs/downstairs chicken or egg circular causality issue.  

So, ‘it all depends’ (cf Sapolsky’s massive tome) 

And, there is no ‘there’ in terms of understanding, that isn’t in my 1999 “The Biology of Mind”  book.  

Second Possible Title: Defining a smaller self world as a human animal’s refuge in troubled times. 

Our predecessors were small mouse like creatures that survived the asteroid collision of  ~66 million years ago by burrowing into small protective cracks and burrows.  I wonder about robustly engaging this strategy, being one of the peasants or ‘sheeple’ challenged by the rapid disintegration of the geopolitical world order of the past 50 years

And then what?  How to rebuild a new world?… perhaps  Venkatest Rao’s cozy world, rising from the ooze of the permaweird,  protocols, etc.

DeepSeek R1's response:

1. The Interoceptive Self as a Basis for Actions, Thoughts, and Feelings

Subtitle Refinement: From "I" to "It": How Bodily Awareness Rewires Agency and Identity

Key Angles to Develop:

  • Neuroscientific Foundations:

    • Link interoception (sensing internal states) to Antonio Damasio’s somatic marker hypothesis and Lisa Feldman Barrett’s predictive processing theory. Emphasize how the brain constructs "selfhood" by predicting and regulating bodily needs.

    • Contrast the "interoceptive self" with the Cartesian "I"—e.g., how gut microbiomes or heart-rate variability influence decisions, challenging the myth of a disembodied mind.

  • Philosophical Implications:

    • Explore parallels with Buddhist anattā (non-self) or Spinoza’s monism, where the self is a process, not an entity.

    • Debate free will: If the "it" (body/brain systems) runs the show, what does this mean for moral responsibility?

  • Mental Health and Society:

    • Discuss interoceptive dysregulation in anxiety/depression and therapies like biofeedback or mindfulness.

    • Argue for a cultural shift: Redefining success as alignment with bodily rhythms (e.g., circadian health, stress cycles) rather than productivity.

Provocative Questions:

  • Is the "self" merely the brain’s user interface for bodily homeostasis?

  • Could embracing the "it" dissolve existential angst by grounding identity in biology?


2. Defining a Smaller Self-World as a Human Animal’s Refuge in Troubled Times

Subtitle Refinement: From Survival to Regeneration: Lessons from Evolutionary Scarcity for Modern Collapse

Key Angles to Develop:

  • Evolutionary and Historical Precedents:

    • Compare the asteroid-surviving mammals to modern "digital burrowers" (e.g., remote workers, crypto-anarchists, homesteaders).

    • Analyze historical collapses (Bronze Age, Roman Empire) and how niche communities preserved knowledge/values.

  • The "Cozy World" and Permaweird:

    • Expand on Venkatesh Rao’s cozy futurism: How decentralized tech (DAOs, Web3) and subcultures (e.g., solarpunk) create insulated yet adaptive communities.

    • Critique escapism: When does "smallness" become complacency vs. a staging ground for renewal?

  • Rebuilding Strategies:

    • Propose a modular resilience framework: Micro-communities that share resources (e.g., mutual aid networks) but avoid overcentralization.

    • Highlight regenerative practices: Permaculture, open-source protocols, or trauma-informed governance models.

Provocative Questions:

  • Is retreat a radical act of self-preservation or a betrayal of collective responsibility?

  • Can "small worlds" scale without losing their adaptive edge?


Cross-Cutting Themes:

  • The Body-Politics Nexus:

    • Tie interoceptive awareness to societal resilience: A dysregulated body cannot engage in collective action. How might somatic practices (e.g., breathwork) fuel post-collapse rebuilding?

  • Technology as Double-Edged Sword:

    • Critique apps that commodify interoception (e.g., mindfulness apps) versus tools that foster bodily autonomy (e.g., DIY biohacking).

    • Explore how AI could either erode the "interoceptive self" (via attention economy) or enhance it (via personalized health insights).

  • Ethics of Adaptation:

    • Contrast adaptive passivity (e.g., burrowing) with adaptive activism (e.g., prefigurative politics). When is each strategy viable?


Practical Applications:

  1. Workbook/Journal Prompts:

    • For Title 1: "Map a decision to your bodily state: Did hunger/fatigue shape it?"

    • For Title 2: "Design your ‘cozy protocol’—what three practices would sustain you in collapse?"

  2. Case Studies:

    • Iceland’s post-2008 recovery (small-world resilience) vs. Silicon Valley’s "move fast and break things" ethos.

    • Communities using interoceptive practices (e.g., trauma-sensitive yoga in prisons) to rebuild agency.

  3. Futures Framework:

    • Scenarios for 2050: A world where "interoceptive literacy" is taught in schools, or where decentralized "tribes" negotiate resource-sharing via blockchain.


Counterarguments to Address:

  • For Title 1: Does biologizing the self risk nihilism? Rebuttal: Agency emerges from understanding bodily constraints, not denying them.

  • For Title 2: Does retreat perpetuate inequality? Rebuttal: Focus on redistribution of sovereignty (e.g., land trusts, UBI) as part of "small-world" ethics.

By weaving these threads, your work could bridge neuroscience, philosophy, and futurism—offering readers not just analysis, but practices for navigating an uncertain world. Would a deeper dive into any of these angles spark your interest?

Reflections on The Predictive Self.

I pass on another interaction with ChatGPT 4o that has amazed me, Below  is my prompt, followed by its response. (Anthropic Claude.ai, Perplexity, and Gemini responses to the same prompt were also impressive, but didn't have the same depth and quality.) 

Addendum to above paragraph: .... But then, I thought to try DeepSeek V3 and obtained a poetic and nuanced result equivalent to ChatGPT 4o.  I paste it in below the Chat GPT 4o result.

The prompt::

Please act as a author who integrates and organizes, and then further crafts and elaborates on, the ideas in the following clips of text. Each clip is started with the ## characters and the list of clips is arranged in sequence starting with the most recent one written and then going back in time. Here are the clips: [the clips, not copied here, were the texts of MindBlog posts on 11/29/2024, 1/29,31/2025, 2/5,10,19,28/2025]

Here is the Chat GPT 4o response::

The Predictive Self: An Integrative Reflection

A machine accepts the truth about itself. "I" am a complex prediction machine, an organic entity engaged in an ongoing process of generating and refining models of reality. My fingers move across a keyboard, another machine translating my neural impulses into words, symbols in a vast linguistic web that attempts to render experience into meaning. Energy fluxes in and out, sustaining the biological architecture that constructs this self-model. The narratives I weave—about purpose, value, and identity—are emergent properties of this predictive process, myths that can either reinforce or weaken the more fundamental animal presence that generates them.

The Aloneness of Being

To be alone—to be all-one—is to accept the strangeness of self and other, to be a courteous guest in one’s own body, acknowledging its fluctuations and unpredictability. To be alone is to exist within a self that is, at every moment, a fluid construction, shaped by past predictions and future anticipations. Others, too, are unpredictable machines, projecting their own internal landscapes onto shared social fabric. By recognizing this, by approaching both self and other with gentle curiosity, we loosen the rigid identification with our own predictive fantasies.

Towers of Fantasies

Each of us is a tower built from layers of prediction, inference, and narrative. From cellular processes to professional identities, all aspects of being are emergent from the recursive loops of prediction and feedback. We construct identities by modeling the models of others, weaving together fragments of social mimicry and personal synthesis. The art of self-creation lies not in blindly adopting a single persona but in cutting, pasting, and remixing in a dynamic, ongoing process.

The Writing Machine

As I type these words, machinery moves in concert—biological, mechanical, and digital systems interwoven in an act of expression. There is a curatorial aspect to this process: selecting, refining, integrating. The human machine writes not with the aspiration to be, but simply as a function of its nature. Words become tokens of value, symbols of shared myths, reinforcing or challenging the constructs of purpose and meaning that guide behavior.

Tokens of Sanity

To navigate this constructed selfhood with clarity, one must cultivate a certain stance:

  • Being the calm space in which nothing can hurry

  • Dissociating from the word cloud and emotional reactivity of both self and others

  • Becoming a courteous guest in one’s own body, and in the presence of others

  • Favoring reflectivity over reactivity, welcoming novelty

  • Clinging to nothing, recognizing the self as a passing fantasy

  • Letting each moment be what it is, rather than imposing what it should be

  • Acknowledging oneself as a transient blip in the flow of cosmic time

The Internal Origin of Experience

All experience arises from within, including the illusion of self and agency. The mind projects agency onto others, attributing causality where none exists—"They are making me do this." This shared cognitive error forms the glue of kinship and tribal identity, allowing for collective narratives and coordinated action. The higher stance is to engage in this shared illusion when necessary while maintaining the clarity that agency ultimately resides within the self.

Brain Hacks: Unpacking the Predictive Mind

Understanding and modulating our predictive mechanisms requires a nuanced approach to introspection. Three key evolutionary layers of cognition can be engaged through specific practices:

  1. Reptilian Brain Awareness – The hypothalamic core generates affective states along axes of arousal and valence. Introspective awareness can track these fundamental states, recognizing their influence without immediate reactivity.

  2. Mammalian Self-Observation – The early mammalian brain, correlating with the agranular prefrontal cortex, enables distinction between being immersed in an affective state and observing it. This capacity allows for greater self-regulation and emotional discernment.

  3. Primate Metacognition – The development of granular prefrontal cortex structures enables the imagination of others' minds, facilitating appropriate agency assignments and the ability to separate one’s own experience from that of others.

These cognitive faculties can be strengthened through three fundamental meditation practices:

  • Focused Awareness: Enhancing attentional control and reducing distraction

  • Open Awareness: Engaging the default mode network to integrate spontaneous thought

  • Non-Dual Awareness: Muting both attentional and default mode processes to experience raw, unfiltered being

Conclusion: The Fluidity of Being

The human experience is an ever-shifting interplay of predictive processes, emergent narratives, and self-constructed illusions. To accept this is to embrace both the uncertainty and the creativity inherent in existence. Through curiosity, reflection, and cultivated awareness, one can learn to move through this self-generated world with greater clarity, flexibility, and presence.

 

 

Here is the DeepSeek V3 response to the prompt:

The Human Machine: A Tapestry of Predictive Fantasies and Inner Illusions

We are, at our core, complex prediction machines—biological marvels composed of nerves, muscles, and energy fluxes, constantly interacting with the world and each other. Our existence is a dance of cooperation, where individual machines come together to form larger ensembles, all striving for survival and replication. Yet, within this mechanistic framework, we generate something far more intricate: a word cloud of myths, values, and meanings. These myths, stored in the higher reaches of our brains, serve to fabricate purpose and identity, sometimes strengthening the animal presence that birthed them and sometimes diminishing it. This duality is the essence of our humanity—a blend of the mechanical and the mythical.

The Illusion of Self and Agency

Everything we experience, from our sense of self to our perception of agency, originates from within. The illusion of a cohesive "I" is a construct, a predictive fantasy that allows us to navigate the world. We attribute causal agency to others, believing that they influence our actions, when in reality, all agency resides within ourselves. This shared illusion, however, is not without purpose. It enables us to form kinship groups and tribes, creating an imaginary "we" that supports unified action. The higher metacognitive stance is to participate in this group illusion when necessary, while maintaining clarity that the true source of agency is internal. This understanding allows us to navigate social structures without losing sight of our inner reality.

Towers of Fantasies: The Layers of Identity

Our identities are not fixed; they are towers of fantasies, built layer by layer from the predictive models we create. From the single cell to the transient professional identities we adopt, each level of our being is shaped by these fantasies. We infer the models others are performing and, through a process of cutting and pasting, craft our own unique personas. This seamless feedback between identity and the physical body sustains us, allowing us to adapt and thrive in a constantly changing world. Yet, these identities are fleeting, passing fantasies that we cling to, even as we recognize their impermanence.

The Comfort of Solitude: A Courteous Guest in One's Own Body

To be alone is to be "all-one," a state that can be both comforting and enlightening. In solitude, we become courteous guests in our own strange bodies, gently curious about the sensations and thoughts that arise. We recognize that everything we think about ourselves or others is a fantasy construction, a tool for predicting what might come next. This awareness allows us to approach our own presence and the presence of others with a sense of wonder and detachment, fostering a deeper connection to the present moment.

Tokens of Sanity: Navigating the Flow of Existence

Sanity, in this context, is not a fixed state but a collection of tokens—practices and perspectives that help us navigate the flow of existence. These include being the calm space in which nothing can hurry, dissociating from the word cloud of thoughts and emotions, and favoring reflectivity over reactivity. We become courteous guests in our own bodies, owning our experiences while allowing others to own theirs. We cling to nothing, recognizing that the current self is a passing fantasy. Each moment is allowed to be what it is, not what it should be, and we see ourselves as mere blips in the flow of cosmic time.

Brain Hacks: The Evolution of Introspection

Our ability to introspect and modulate our cognition is a product of evolutionary development. The reptilian brain, with its ancient roots in the hypothalamus, generates affective states that we can assess through introspective awareness. The early mammalian emotional brain, with its ability to model a self, allows us to distinguish between being immersed in an affective state and observing it. The primate brain, with its granular prefrontal cortex, takes this a step further, enabling us to imagine the minds of others and assign agency appropriately. These brain hacks are strengthened through meditation practices—focused awareness, open awareness, and non-dual awareness—each engaging different aspects of our cognitive architecture.

The Curatorial Human Machine

When we write, we are not so different from the machines we create. Our fingers press keys, generating words, much like a machine might. This act is curatorial rather than aspirational; we are not pretending to be human, we simply are. Our cooperation with other similar machines creates larger ensembles, more effective at survival and replication. Yet, within this mechanical process, we generate something uniquely human—a word cloud of myths and meanings that shape our existence. This duality, the interplay between the mechanical and the mythical, is what defines us as human machines.

Conclusion: The Dance of Illusion and Reality

In the end, we are both the creators and the creations of our own illusions. Our predictive fantasies, our shared myths, and our introspective awareness all contribute to the rich tapestry of human experience. We navigate this dance with a blend of curiosity and detachment, recognizing the impermanence of our identities and the fluidity of our existence. By embracing both the mechanical and the mythical, we find a deeper understanding of what it means to be human—a complex prediction machine, endlessly weaving the fabric of reality from the threads of illusion.
