From this 2025 book by smoking hot Cambridge University neuoroscience and politics professor Leor Zmigrod<\/a>:<\/p>\n

I believe that we can judge an ideology based on what believing in it does to human bodies and brains; on whether being a passionate believer narrows our movements, lassoes our flexibility, restricts our responses, or triggers us to commit violence. If we have less scope for plasticity and change and less direct access to our sensations, we are at risk of dehumanizing ourselves and others. We become less sensitive, less elastic, less authentic. If we see reality through an ideological lens, we end up avoiding the richness of existence in favor of a more reduced, stereotyped experience. By studying the ideological brain with neuroimaging devices and cognitive tests, we can illuminate previously invisible forms of domination. With the tools of science, we can develop new ways to critique ideologies.
\n Perhaps some ideologies will pass our critical tests. Many will not. We might accidentally become suspicious of our most treasured ideological possessions. A science of ideology can inspire us to question our idols, our icons, our metaphors, our imagined utopias. It can stimulate careful analysis and honest self – reflection. It can even become the basis for personal or social action. Examining the neurocognitive origins and consequences of our beliefs \u2014 where they come from and how they transform our bodies \u2014 will offer clues regarding the kind of belief systems we might wish to keep and which ones we might be persuaded to let go.
\n Believing passionately in a rigid doctrine is a process that spills into our neurons, flowing into our bodies. Ideologies are not mere envelopes for our lives; they enter our skins, our skulls, our nerve cells. Totalizing ideologies shape the brain as a whole, not simply the brain when it is confronted with political propositions or debates. Science is beginning to reveal that the profound reverberations of ideologies can be observed in the brain even when we are not engaging with politics at all. Since our brains learn to embody indoctrination in deep and insidious ways, the social rituals we learn to enact can become the biological realities of our minds and bodies. There is therefore a danger that when an individual is immersed in rigid ideologies, it is not only their political opinions and moral tastes that are being sculpted \u2014 their entire brain is being sculpted to.<\/p><\/blockquote>\n

All beliefs are just unnecessary muscular tension, according to a perspective I heard in the Alexander Technique.<\/p>\n

I don’t see how any ideology could promote flexibility?<\/p>\n

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.<\/p>\n

Grok says: <\/p>\n

Not all beliefs are inherently negative or tension-inducing; some can be adaptive or motivating without causing physical or mental rigidity. The Alexander Technique\u2019s focus is less on eliminating beliefs and more on cultivating awareness to avoid unnecessary effort\u2014whether that effort is physical (like tensing muscles) or mental (like clinging to unexamined assumptions).<\/p>\n

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\u2014broad belief systems\u2014can 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\u2014the brain’s ability to adapt and reorganize. <\/p>\n

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. <\/p>\n

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\u2014echoing the Alexander perspective. <\/p>\n

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\u2014measured through tasks like the Wisconsin Card Sorting Test, where adaptable people shift rules fluidly\u2014can counteract this. <\/p>\n

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. <\/p>\n

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. <\/p>\n

How Belief Systems Could Promote Physical Flexibility and Release<\/p>\n

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:<\/p>\n

Encouraging Self-Reflection and Questioning: Beliefs rooted in honest self-examination\u2014 like scientific inquiry or mindfulness practices\u2014prompt 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. <\/p>\n

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. <\/p>\n

Physically, this might manifest as greater bodily awareness and release, akin to how Alexander lessons teach inhibiting fixed reactions for freer movement.<\/p>\n

Nurturing Elasticity Through Habits: Zmigrod highlights that flexible belief systems resist polarization by embracing complexity, leading to a “fluid, expansive state of existence.” <\/p>\n

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.<\/p>\n

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\u2014mentally unclenching to physically unwind. <\/p>\n

Yes, there\u2019s emerging evidence from neuroscience, psychology, and somatic practices like the Alexander Technique that certain belief systems\u2014those fostering cognitive flexibility, open-mindedness, and self-awareness\u2014can promote physical flexibility by reducing stress-induced tension and enhancing mind-body integration.<\/p>\n

1. Cognitive Flexibility and Physical Relaxation<\/p>\n

Belief systems that encourage cognitive flexibility\u2014adaptability in thinking, openness to new evidence, and reduced attachment to rigid doctrines\u2014have been linked to lower stress responses, which directly influence physical flexibility. Zmigrod\u2019s 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.<\/p>\n

Evidence: <\/p>\n

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.<\/p>\n

Alexander Technique Connection: The Technique emphasizes \u201cinhibition\u201d of habitual reactions, which aligns with cognitive flexibility. By letting go of fixed mental patterns (e.g., \u201cI must always be right\u201d), practitioners often report reduced muscular tension, as seen in studies where Alexander lessons improved posture and reduced pain in conditions like back pain.<\/p>\n

2. Mindfulness-Based Beliefs and Bodily Awareness<\/p>\n

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 \u201cdirect access to sensations\u201d 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.<\/p>\n

Alexander Technique Connection: The Technique trains individuals to notice and release unnecessary tension during movement, akin to mindfulness. A belief in the process of \u201cnon-doing\u201d (a core Alexander principle) fosters a relaxed, open state, with studies showing improved flexibility in musicians and office workers after lessons.<\/p>\n

3. Open-Minded Belief Systems and Stress Reduction<\/p>\n

Beliefs that embrace complexity and pluralism, as Zmigrod advocates, reduce the \u201classoing\u201d of flexibility by avoiding polarized thinking. Such beliefs\u2014e.g., valuing evidence over dogma or embracing philosophical skepticism\u2014lower psychological stress, which can manifest as physical suppleness.Evidence: Zmigrod\u2019s 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.<\/p>\n

Alexander Technique Connection: The Technique\u2019s emphasis on releasing \u201cend-gaining\u201d (rigid pursuit of goals) mirrors open-minded beliefs, reducing tension. Practitioners often report feeling \u201clighter\u201d and more flexible, as mental openness translates to physical release.<\/p>\n

4. Neuroscientific Insights on Ideology and Embodiment<\/p>\n

Zmigrod\u2019s 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.<\/p>\n

Alexander Technique Connection: The Technique\u2019s 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.<\/p>\n

Practical Implications<\/p>\n

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.
\nScientific or skeptical frameworks, which encourage questioning and adaptability, lowering stress and its physical manifestations.
\nSomatic practices (e.g., Alexander Technique, yoga), which integrate beliefs in mind-body unity with physical training to release tension.<\/p>\n

Limitations and Considerations<\/p>\n

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. <\/p><\/blockquote>\n
