Trust the Body

One-liner: Fog, exhaustion, and self-doubt after an interaction are data, worth logging and checking against the facts, not a verdict on their own.

What it is

Reading your own instruments is a skill you practice, not a verdict your body hands down for you.

Interoception, the brain’s ongoing reading of internal signals from the heart, lungs, and gut, is a genuine and active area of peer-reviewed research. Work by Hugo Critchley and Sarah Garfinkel has shown that interoceptive signals meaningfully shape emotion, decision-making, and intuitive judgment, often ahead of conscious reasoning catching up. Physical sensations like a tight chest, a stomach drop, sudden fatigue, or fog after a conversation are a real read on something, and treating recurring physical after-effects as legitimate information rather than overreaction is a documented feature of trauma-informed and somatic approaches to recognizing harmful dynamics.

Polyvagal theory, developed by Stephen Porges, is the popular clinical framework most often cited alongside this idea, and it’s worth being direct about its standing: it is influential in clinical practice, but its specific physiological and evolutionary claims are seriously contested. In February 2026, Paul Grossman and thirty-eight co-authors published a peer-reviewed critique in Clinical Neuropsychiatry concluding the theory’s core claims about autonomic organization are not defensible against current neurophysiological evidence, following earlier critiques from Grossman in 2007, 2016, and 2023. Porges and others have pushed back hard on that critique in turn. This entry doesn’t need the contested theory to hold up. The part that’s load-bearing is simpler and doesn’t depend on which side of that argument is right: a logged pattern of consistent physiological responses tied to one specific person, across many separate interactions, is legitimate pattern evidence regardless of which theory ends up explaining the underlying physiology.

The lever this exploits is timing, not mysticism. Your body is processing the interaction continuously, not just the words spoken but tone, pacing, contradiction, before your conscious mind has finished assembling an explanation. That head start is real. What it isn’t, on any single occasion, is proof. It becomes evidence only once you’ve logged it enough times to see whether it’s a pattern.

What it looks like: the fog, the log, the convergence

The fog: Mid-1:1, the familiar fog rolls in as your manager retells the timeline wrong, again. You don’t argue with the fog and you don’t obey it either. You flag it silently, “noted, log it later,” take a slow exhale, and say out loud, “Let me confirm that against my notes and get back to you.” You leave the decision unmade.

The log: That evening, two lines: date, person, sensation, what preceded it. The same format as your factual log.

The convergence: Entry number five in the somatic log lines up, again, with the factual log’s own entry about the same disputed timeline. You no longer ask yourself if you’re too sensitive. You check your instruments, cross-check your records, and trust the convergence between the two, not either one alone.

Putting it into practice

1. In the moment, when fog or a stomach-drop arrives mid-conversation, don’t argue with it and don’t obey it. Flag it internally (“noted, log it later”), take one slow exhale, and buy processing time with a deferral phrase: “Let me get back to you on that.” This prevents decisions made from inside the fog itself. Fog is often the felt signature of a reality-rewrite in progress, see Gaslighting and group gaslighting / manufactured false consensus; it can also be the physiological trace left by deniable content with no words you can point to, see covert digs / dog-whistling and implied accusation.
2. Same day, write the two-line somatic log entry: date, person, sensation, what preceded it. Same format as an incident log, on purpose.
3. Weekly, cross-reference the somatic log against your factual one, see Document Contemporaneously. The convergence of the two logs is the actual finding here; either one alone is just a data point, see plausible deniability for how this convergence is what makes an otherwise-deniable pattern visible at all.
4. Deliberately collect counter-examples. Log interactions with ordinary colleagues that leave you fine, to separate a real signal from generalized anxiety; see trusting ordinary colleagues again and getting your own judgment back.
5. Escalate persistent symptoms to a professional. Somatic signals are a starting point for insight, not a clinical diagnosis you make alone; see Hypervigilance Outlives the Job.

What goes wrong without preparation: treating every flutter as a verdict, when anxiety and unrelated stress produce the same sensations a real pattern would; explaining the sensation away before you’ve logged it, which erases the data point before it can join a pattern; and logging feelings without ever cross-referencing the facts, which produces a mood diary instead of evidence.

Why this works

Three tiers, and only the third one is fully load-bearing. First, interoception research proper: Critchley and Garfinkel’s work shows the brain continuously integrates internal bodily signals into feeling states that genuinely inform judgment before verbal reasoning finishes, a finding with real peer-reviewed standing, alongside the related and itself still-debated somatic marker hypothesis from Antonio Damasio. Second, polyvagal theory, kept here as the popular clinical framework it is, with its specific physiological and evolutionary claims openly contested, most recently by the 2026 Grossman et al. critique described above. Third, and this is the part that needs neither of the first two to be fully settled: a consistently logged physiological response, tied to one person, across many interactions, is legitimate pattern evidence on its own terms. You don’t need a settled theory of why your body reacts the way it does to trust that it reacts the same way, reliably, to the same person, and that the reliability itself is worth taking seriously.

Caution: Body signals are a prompt to investigate, not proof on their own: anxiety, unrelated stress, or your own history can also produce these sensations, so pair somatic noticing with factual documentation rather than treating a feeling as a verdict. Persistent physical symptoms (chronic insomnia, panic, health decline) warrant a doctor or therapist, not just a workplace strategy.

Cross-links: Gaslighting and Group Gaslighting / Manufactured False Consensus, the rewrites whose felt signature is often exactly this fog; Covert Digs / Dog Whistling and Implied Accusation, deniable words paired with consistent physiology; Plausible Deniability, what the two-log convergence defeats; Document Contemporaneously, the factual log this cross-references against every week; Getting Your Own Judgment Back and Trusting Ordinary Colleagues Again, calibrating the instrument itself, not just reading it; Hypervigilance Outlives the Job, what persistent, unresolved signals can become if left unaddressed.

Label note: Interoception is a genuinely active, peer-reviewed research area, which is what earns this entry its “academic” label. Polyvagal theory specifically, the framework most people associate with “the body keeps score,” is an influential clinical model whose core physiological claims are seriously contested in the scientific literature, most recently and forcefully in a 2026 critique signed by thirty-nine researchers. The practical technique here, logging somatic signals and cross-referencing them against a factual log, is this site’s own descriptive application, and it doesn’t depend on polyvagal theory being right to be worth doing.
