All beliefs are just unnecessary muscular tension, according to a perspective I heard in the Alexander Technique.
You can experience the difference yourself when you shift between awareness and judgment. Whenever you judge, you tighten up. When you move out of judgment into awareness, your body frees up.
Not all beliefs are inherently negative or tension-inducing; some can be adaptive or motivating without causing physical or mental rigidity. The Alexander Technique’s focus is less on eliminating beliefs and more on cultivating awareness to avoid unnecessary effort—whether that effort is physical (like tensing muscles) or mental (like clinging to unexamined assumptions).
In the Technique, rigid mental habits (like clinging to fixed ideas) often translate into physical holding patterns, such as tightened shoulders or a clenched jaw, restricting ease and movement. Zmigrod’s work takes this a step further by using neuroscience to show how ideologies—broad belief systems—can either entrench this rigidity across brain, body, and behavior or, conversely, cultivate flexibility and release. You’re right to question how a belief system could actively promote physical flexibility and release, as the quote primarily critiques restrictive ideologies; however, drawing from her research and related discussions, we can infer what “flexible” belief systems might look like and how they could foster that release.Understanding Rigidity vs. Flexibility in BeliefsZmigrod argues that rigid doctrines “spill into our neurons, flowing into our bodies,” sculpting the brain holistically and reducing plasticity—the brain’s ability to adapt and reorganize.
This isn’t just metaphorical: neuroimaging and cognitive tests reveal that dogmatic thinking correlates with less neural adaptability, even in non-political tasks, leading to narrowed movements, restricted responses, and diminished access to sensations.
For instance, stress from ideological adherence can rigidify thought patterns, making individuals more habitual and less responsive, which might physically manifest as tension or reduced bodily awareness—echoing the Alexander perspective.
In essence, such beliefs create a “lassoed” state, where the body embodies the mental constriction, potentially increasing muscular tension as a stress response.On the flip side, Zmigrod suggests that belief systems promoting cognitive flexibility—measured through tasks like the Wisconsin Card Sorting Test, where adaptable people shift rules fluidly—can counteract this.
Flexible thinkers are open to evidence, plurality, and change without being easily swayed, leading to greater mental elasticity that “rebounds” post-stress and enhances sensitivity to experiences.
This ties directly to physical release: just as physical fitness values elasticity to prevent injury and enable fluid movement, mental flexibility can reduce the embodied tension of dogma, allowing for more authentic, expansive living.
How Belief Systems Could Promote Physical Flexibility and Release
Based on Zmigrod’s framework, a belief system that “passes critical tests” would encourage plasticity and direct access to sensations, avoiding the dehumanizing effects of stereotypes or totalizing views. Here’s how such systems might work, with connections to bodily release:
Encouraging Self-Reflection and Questioning: Beliefs rooted in honest self-examination— like scientific inquiry or mindfulness practices—prompt us to “question our idols” and metaphors, as per the quote. This reduces mental clinging, which in Alexander terms releases unnecessary tension. For example, a belief in ongoing personal growth (e.g., via cognitive behavioral approaches) could train the brain to interrogate habits, correlating with less rigidity in daily routines and more physical ease.
Fostering Open-Mindedness and Plurality: Ideologies that value diversity and evidence over conformity promote neural adaptability, making individuals less prone to the “profound reverberations” that sculpt the brain rigidly. Zmigrod’s studies link this to disbelief in absolute doctrines (e.g., flexible religiosity or atheism), where cognitive persistence gives way to openness, potentially easing physiological responses like stress-induced tension.
Physically, this might manifest as greater bodily awareness and release, akin to how Alexander lessons teach inhibiting fixed reactions for freer movement.
Nurturing Elasticity Through Habits: Zmigrod highlights that flexible belief systems resist polarization by embracing complexity, leading to a “fluid, expansive state of existence.”
Practices like meditation or philosophical skepticism could embody this, reducing the “insidious” indoctrination that affects sensations and promoting rebound plasticity. In body terms, this aligns with releasing tension by not “adhering to scripts,” allowing for more elastic responses in posture and action.
Ultimately, Zmigrod envisions a “science of ideology” as a tool for choosing beliefs that enhance authenticity and sensitivity, rather than narrowing existence. If a system inspires action through reflection without demanding conformity, it could promote the very release you’re pondering—mentally unclenching to physically unwind.
Yes, there’s emerging evidence from neuroscience, psychology, and somatic practices like the Alexander Technique that certain belief systems—those fostering cognitive flexibility, open-mindedness, and self-awareness—can promote physical flexibility by reducing stress-induced tension and enhancing mind-body integration.
1. Cognitive Flexibility and Physical Relaxation
Belief systems that encourage cognitive flexibility—adaptability in thinking, openness to new evidence, and reduced attachment to rigid doctrines—have been linked to lower stress responses, which directly influence physical flexibility. Zmigrod’s research, as discussed in The Ideological Brain (2025), uses neuroimaging and cognitive tests (e.g., Wisconsin Card Sorting Test) to show that flexible thinkers exhibit greater neural plasticity, allowing them to shift mental frameworks fluidly. This mental elasticity correlates with reduced physiological stress, as rigid ideologies (e.g., dogmatic political or religious beliefs) can elevate cortisol levels, leading to muscle tension and restricted movement.
Evidence:
Studies show that cognitive flexibility, measured by tasks requiring rule-switching, is associated with lower sympathetic nervous system activation (e.g., reduced heart rate variability stress markers). Less stress means less involuntary muscle bracing, promoting physical ease. For example, a 2020 study in Frontiers in Psychology found that individuals with higher cognitive flexibility had better stress recovery, which could translate to less chronic tension in muscles like the neck or shoulders.
Alexander Technique Connection: The Technique emphasizes “inhibition” of habitual reactions, which aligns with cognitive flexibility. By letting go of fixed mental patterns (e.g., “I must always be right”), practitioners often report reduced muscular tension, as seen in studies where Alexander lessons improved posture and reduced pain in conditions like back pain.
2. Mindfulness-Based Beliefs and Bodily Awareness
Belief systems rooted in mindfulness or self-reflection, such as those inspired by meditation or somatic practices, enhance bodily awareness and reduce tension, fostering physical flexibility. Zmigrod notes that beliefs promoting “direct access to sensations” counteract the desensitizing effects of rigid ideologies. Mindfulness practices, which often embody flexible, non-judgmental beliefs, have been shown to lower muscle tension and improve movement range.Evidence: A 2018 meta-analysis in Scientific Reports found that mindfulness meditation reduces cortisol and improves vagal tone, leading to relaxed muscle states and better joint mobility in practitioners. Another study in Pain Medicine (2019) showed that mindfulness-based interventions improved physical flexibility in chronic pain patients by reducing fear-avoidance behaviors, which often manifest as muscular guarding.
Alexander Technique Connection: The Technique trains individuals to notice and release unnecessary tension during movement, akin to mindfulness. A belief in the process of “non-doing” (a core Alexander principle) fosters a relaxed, open state, with studies showing improved flexibility in musicians and office workers after lessons.
3. Open-Minded Belief Systems and Stress Reduction
Beliefs that embrace complexity and pluralism, as Zmigrod advocates, reduce the “lassoing” of flexibility by avoiding polarized thinking. Such beliefs—e.g., valuing evidence over dogma or embracing philosophical skepticism—lower psychological stress, which can manifest as physical suppleness.Evidence: Zmigrod’s studies suggest that individuals with less dogmatic beliefs (e.g., flexible religiosity or openness to diverse perspectives) show greater cognitive persistence and adaptability, linked to lower stress-induced muscle tension. A 2021 study in Nature Communications found that open-mindedness correlates with reduced amygdala activation (a stress marker), which could decrease physical bracing. Additionally, practices like yoga, often tied to non-dogmatic beliefs in holistic well-being, improve flexibility through combined mental and physical training, as shown in a 2020 Journal of Bodywork and Movement Therapies study.
Alexander Technique Connection: The Technique’s emphasis on releasing “end-gaining” (rigid pursuit of goals) mirrors open-minded beliefs, reducing tension. Practitioners often report feeling “lighter” and more flexible, as mental openness translates to physical release.
4. Neuroscientific Insights on Ideology and Embodiment
Zmigrod’s work highlights that ideologies sculpt the brain holistically, affecting even non-political tasks. Rigid beliefs can entrench neural pathways, reducing plasticity and increasing embodied tension (e.g., through chronic stress responses). Conversely, beliefs that foster curiosity and adaptability enhance neural flexibility, which may promote physical flexibility by reducing stress-related muscle tightness.Evidence: Neuroimaging studies show that rigid ideological adherence (e.g., extreme political views) correlates with heightened activity in the default mode network and reduced prefrontal cortex flexibility, linked to stress and physical tension. In contrast, beliefs encouraging exploration (e.g., scientific inquiry) enhance prefrontal activity, supporting adaptive responses and potentially reducing somatic tension. A 2022 study in Neuroscience & Biobehavioral Reviews suggests that flexible cognitive styles improve sensorimotor integration, aiding fluid movement.
Alexander Technique Connection: The Technique’s focus on mindful movement retrains sensorimotor habits, aligning with beliefs that prioritize adaptability. This can lead to measurable improvements in flexibility, as seen in trials where Alexander training enhanced mobility in older adults.
Practical Implications
Belief systems that promote physical flexibility often share traits like openness, self-reflection, and non-attachment to rigid outcomes. Examples include:Mindfulness or meditation-based beliefs, which reduce stress and enhance bodily awareness, leading to relaxed muscles and improved range of motion.
Scientific or skeptical frameworks, which encourage questioning and adaptability, lowering stress and its physical manifestations.
Somatic practices (e.g., Alexander Technique, yoga), which integrate beliefs in mind-body unity with physical training to release tension.
Limitations and Considerations
While evidence supports that flexible beliefs reduce stress and tension, direct studies linking specific ideologies to physical flexibility (e.g., joint range of motion) are sparse. Most data focus on stress reduction or cognitive outcomes, with physical flexibility inferred through reduced tension. Additionally, individual differences (e.g., baseline fitness or psychological resilience) may mediate these effects.
How Stephen P. Turner might critique Leor Zmigrod’s The Ideological Brain: The Radical Science of Flexible Thinking
Book: Leor Zmigrod, The Ideological Brain (on sale Mar 25, 2025). See publisher page here, and coverage in the Financial Times, Vox, an excerpt in the Harvard Gazette, and a profile via Gates Cambridge.
The short version
- Turner would applaud the book’s interdisciplinary reach (neuroscience, psychology, politics) but argue it overdraws on biology at the expense of sociology and institutional analysis (FT review).
- He’d insist that ideology is forged in practices, institutions, and expert systems—not just inside individual brains (The Social Theory of Practices).
- He’d caution against biological determinism: neural findings matter, but social structures entrench or loosen rigidity (USF bio).
Where Turner would agree—and where he’d push back
Zmigrod synthesizes evidence that “cognitive rigidity” correlates with ideological dogmatism and extremism, drawing on tasks like the Wisconsin Card Sorting Test and research on dopaminergic systems (Vox; WCST; JOCN 2021; overview in FT). Turner wouldn’t dispute that these correlations are interesting. His critique is about framing:
- From brains to practices: Turner’s work treats ideology as emerging from socially transmitted practices, institutional routines, and expert regimes of knowledge—not primarily from individual neurobiology (Turner 1994).
- Institutional epistemics: He’d argue the book underplays how institutions define what counts as “knowledge,” shape incentives, and thereby stabilize or unsettle ideological commitments (USF bio).
- Against determinism creep: Even where Zmigrod is careful to say nature and nurture interact, Turner would press that social organization can manufacture rigidity or flexibility irrespective of baseline neural differences (FT).
The role of the tacit (Turner’s centerpiece)
Turner’s mature view puts the tacit at the center: the unarticulated skills, norms, and background presuppositions that guide how people see and act. He develops this across Understanding the Tacit (2014) and later essays (e.g., “Naturalizing the Tacit,” 2017). Think Polanyi, but sociologized: ideology lives in what goes without saying (tacit knowledge), learned through participation in practices, not just explicit doctrines.
- Socially acquired: Neural flexibility may shape how quickly we learn, but the frames are transmitted tacitly via institutions and communities (review of Understanding the Tacit).
- “What goes without saying”: Deep commitments are often invisible to believers because they’re embedded in background routines, not in articulated propositions (Turner 2014).
- Methodological upshot: You can’t MRI a person’s unspoken social assumptions; you study them historically and sociologically (Turner 1994).
Does the neuroscience still matter?
Yes—especially where it’s careful. Zmigrod’s empirical program linking flexibility/rigidity to ideological styles is serious work (e.g., reviews and studies in Current Opinion in Behavioral Sciences 2020; Current Directions in Psychological Science 2021; and dopaminergic correlates in Journal of Cognitive Neuroscience 2021). Turner’s point is proportionality: don’t let brain data crowd out the institutional and tacit scaffolding that actually generates ideological life.
Stephen Turner might say about this new book: Great neuroscience—but brains don’t think in a vacuum. Ideology is born in social practices, expert institutions, and the tacit distribution of know-how. Biology matters—but only in dialogue with the social world.

Rony Guldmann on The Ideological Brain: The Radical Science of Flexible Thinking
Based on Guldmann’s framework in Conservative Claims of Cultural Oppression, his critique of Leor Zmigrod’s The Ideological Brain would likely focus less on the book’s neuroscience and more on the implicit cultural politics it enacts. He would view Zmigrod’s framing of “cognitive rigidity” as an implicit moral hierarchy that mirrors how liberal elites—what he calls the “progressive Clerisy”—use ostensibly neutral scientific concepts to naturalize their own cultural dominance.
1. The hidden politics of “flexibility”
In Guldmann’s account, liberalism often cloaks its moralistic impulses behind universalist ideals. A research program that correlates ideological rigidity with neurological traits risks recapitulating what he calls the “liberal hero-system”—a secularized moral hierarchy in which openness and flexibility are marks of higher civilization, while rigidity is pathologized as a relic of a pre-modern, less disciplined self. In this light, Zmigrod’s work could be read as supplying a new, neuroscientific vocabulary for an old liberal trope: the conservative as less evolved.
2. The asymmetry problem
Guldmann would be alert to how The Ideological Brain might treat conservative dispositions as deficits to be explained away, while treating liberal dispositions as the unmarked norm. He has argued that this asymmetry mirrors the way dominant groups in history have pathologized the consciousness of the “Other” while leaving their own worldview unexamined. In neuroscience form, this could look like studying the biology of “rigidity” without equally probing the biology of “hyper-flexibility” and its potential downsides.
3. Cultural oppression in scientific guise
From his perspective, even if Zmigrod’s data are robust, the interpretation may unwittingly enact what he terms cultural oppression: the imposition of a liberal form of selfhood—disciplined, cosmopolitan, self-reflective—on those who have not internalized it, and the stigmatization of resistance as cognitive pathology. The very framing of “flexible thinking” as an unquestioned good could, for Guldmann, exemplify the liberal “civilizing mission” in secular-scientific form.
4. The tacit liberal anthropology
Guldmann’s theory stresses that liberalism’s self-image as neutral and purely rational is historically contingent—a product of what he calls the secularization of religious asceticism and courtly sociability. He might say that The Ideological Brain relies on this unexamined anthropology, taking for granted that the ideal mind is detached, adaptive, and open to novelty, rather than recognizing this as one culturally specific way of being human.
5. A possible reframing
Rather than using neuroscience to sort citizens into more or less cognitively “fit” for democracy, Guldmann would push for a symmetrical study of ideological styles that treats liberal and conservative cognitive profiles as parallel adaptations to the modern social order. This would shift the emphasis from curing rigidity to understanding the social and historical conditions that make different cognitive styles adaptive for different groups.
In Guldmann’s idiom: The Ideological Brain may think it’s mapping a universal cognitive virtue, but it’s really drawing a prestige map of the liberal self. Without equal scrutiny of the liberal brain, it risks becoming a high-tech iteration of the very cultural domination it cannot see.
