Hypnosis myths: losing control vs gaining control
Spiegel addresses the two common extremes people believe about hypnosis: that it’s either dangerous mind control or totally useless. He reframes hypnosis as a tool for increasing self-control and experimenting with new behaviors—very different from the caricature of stage hypnosis.
- •Most fears center on “losing control,” but clinical hypnosis aims to enhance control
- •Stage hypnosis can mislead people about what’s really happening
- •Hypnosis lets people temporarily drop rigid self-assumptions and “try on” change
- •Clinical use: rapid shifts in symptoms/behavior, as in Spiegel’s patient work and the Reveri app
- 1:20 – 6:00
What changes in the brain during hypnosis (fMRI findings)
Spiegel explains the core neural signature of hypnosis observed in fMRI studies. He describes three major brain network shifts that reduce interruption/anxiety, increase mind–body coupling, and loosen self-referential narratives.
- •Reduced activity in the dorsal anterior cingulate (salience/alarm network) enables deeper focus
- •Increased connectivity between dorsolateral prefrontal cortex and insula improves interoception and bodily control
- •Decreased coupling between prefrontal cortex and posterior cingulate (default mode network) quiets self-judgment
- •Overall effect: less stress reactivity, fewer distractions, more flexible self-experience
- 6:00 – 8:43
What hypnosis feels like and how it’s induced (fast, practical steps)
Chris asks what the hypnotic process looks like in a scientific/clinical context. Spiegel describes a rapid induction he uses in clinic and argues that all hypnosis is fundamentally self-hypnosis—people are learning to use an ability they already have.
- •Induction can take seconds for hypnotizable people (no long “counting down” needed)
- •Simple protocol: look up, close eyes, deep breath, relax, hand-floating suggestion
- •Hypnosis compared to an unused “app” on your phone—capacity exists, needs activation
- •Analogy: getting absorbed in a movie (belief in imagination, reduced evaluation/judgment)
- 8:43 – 22:34
Why humans are hypnotizable: social bonding and survival under threat
Spiegel argues hypnosis isn’t a hack but an evolved capability. He offers two evolutionary functions: enabling deep social engagement and helping humans modulate fear/pain to survive predation despite relatively weak bodies.
- •Hypnotic absorption supports bonding, shared rituals, and social cohesion
- •Humans’ helpless infancy makes deep social attunement a survival necessity
- •Fear/pain modulation (freeze/dissociation) can reduce movement and evade predators
- •Hypnosis leverages these built-in systems to regulate arousal and perception
- 22:34 – 25:24
Hypnosis vs sleep, meditation, and flow—and a performance example (swimming)
Spiegel differentiates hypnosis from sleep and compares it more closely to focused flow than open-monitoring meditation. He shares how self-hypnosis helped Stanford swimmers shift attention from competitors back to bodily process, improving meet performance.
- •Hypnosis is wakeful, highly focused attention—not sleep
- •Meditation emphasizes open presence; hypnosis often “reprograms” a targeted response
- •Flow similarity: immersion in process over outcome
- •Applied case: swimmers improved by focusing on breath, muscle control, and internal cues
- 25:24 – 30:10
Hypnotizability as a stable trait: highs, mids, lows, and how to test it
Spiegel explains that hypnotizability stabilizes in early adulthood and remains remarkably consistent over decades. He outlines how he evaluates it quickly and adapts his clinical approach depending on whether someone is high, medium, or low in hypnotizability.
- •Trait stability: Zimbardo retest over 25 years shows correlation ~0.7 (similar to IQ stability)
- •Some people are near-nonresponders; others respond dramatically
- •5-minute office assessment using hand-float, dissociation, involuntariness, and “cut-off” signal
- •Clinical tailoring: dramatic imagery for highs, negotiated experimentation for mids, cognitive approaches for lows
- 30:10 – 36:32
Who tends to be hypnotizable: personality patterns, examples, and the COMT gene
Chris probes whether hypnotizability can be inferred from someone’s profile and whether genetics play a role. Spiegel notes certain organized/rigid cognitive styles may correlate with lower responsiveness, and discusses findings linking hypnotizability to COMT dopamine metabolism variants.
- •Organized, highly analytical, control-oriented styles often correlate with lower hypnotizability
- •Case example: extremely analytical patient scores 0 and benefits more from cognitive reframing than hypnosis
- •Genetic link: COMT (catechol-O-methyltransferase) polymorphisms related to dopamine levels
- •Val/Met tends to associate with higher hypnotizability vs Met/Met in Spiegel’s description
- 36:32 – 41:29
Can you increase hypnotizability? Trauma, imagination, and TMS experiments
Spiegel distinguishes between developmental/life experiences that shape hypnotic involvement and attempts to directly increase hypnotizability. He discusses imaginative involvement, dissociation in response to abuse, and a recent study using TMS to transiently boost hypnotizability by targeting the dorsal anterior cingulate.
- •Imaginative involvement in childhood (stories, absorption) may increase hypnotic capacity
- •Trauma/abuse can strengthen dissociation as a coping mechanism
- •TMS experiment: suppressing dorsal anterior cingulate activity can transiently increase hypnotizability
- •Open question: whether temporary boosts create lasting trait changes
- 41:29 – 58:40
In-person vs app hypnosis: smoking cessation and ‘focus on what you’re for’
Spiegel explains that remote hypnosis (via app) can perform similarly to in-person sessions for some outcomes. He shares a striking smoking-cessation protocol emphasizing positive identity and bodily care—plus results from both a live trial and the Reveri app version.
- •Evidence suggests pain/stress reduction can be similar in-person vs remote delivery
- •Smoking strategy: avoid aversion tricks; focus on values (‘for my body…respect and protection’)
- •Single-session study outcomes comparable to medications like varenicline/bupropion
- •Reveri app replicated results: ~1 in 4 quit; others reduced consumption ~50%
- 58:40 – 1:03:23
Training the brain for pain control: EEG evidence and surgical RCT outcomes
Spiegel goes deep on pain as an interpretive brain process, showing how hypnosis can alter early sensory processing. He describes EEG changes under hypnotic analgesia and a randomized trial during invasive vascular procedures demonstrating large reductions in pain, anxiety, opioid use, and procedure time.
- •Pain is shaped by brain salience and attention, not just tissue mechanics
- •EEG evoked responses: early sensory components can diminish under hypnotic analgesia
- •Surgery RCT: standard care vs nurse support vs self-hypnosis training
- •Outcomes: much lower pain/anxiety, ~50% less opioids, fewer complications, faster procedures
- 1:03:23 – 1:07:08
Maximizing self-hypnosis with Reveri: bottom-up stress control and insomnia use
Spiegel explains how Reveri teaches people to regulate bodily arousal first, then think more clearly about problems. He outlines the app’s stress protocol (floating imagery + problem/solution screen) and discusses why insomnia is one of the most common use cases.
- •Approach: start by feeling better physically, then address the stressor cognitively
- •Stress tool: imagine floating; visualize problem on one side and one controllable action on the other
- •Typical short-session outcomes: ~15–20% reductions in stress/pain for many users
- •Insomnia protocol: make body comfortable; project thoughts outward like a movie to reduce arousal
- 1:07:08 – 1:15:13
Combining hypnosis with breathwork: cyclic sighing, box breathing, and lasting effects
Spiegel highlights breathwork as a complementary modality that quickly shifts autonomic state. He teaches “cyclic sighing,” explains the physiology of why long exhales calm the body, and cites data suggesting practice can improve mood and reduce baseline anxiety over time.
- •Breathwork integrates well with hypnosis for rapid downshifting of arousal
- •Cyclic sighing: partial nasal inhale, top-off inhale, long mouth exhale (repeat)
- •Mechanism: exhale increases venous return, boosts parasympathetic ‘rest-and-digest’ activity
- •Study evidence: daily practice can improve mood/anxiety and slow breathing rate over weeks
- 1:15:13 – 1:24:31
Standout clinical cases: trauma, shame, compassion, and perspective shifts
Spiegel shares memorable cases where hypnosis helped patients rapidly reframe shame and traumatic memories. Techniques include compassionate re-parenting imagery and pairing grief with positive memory, producing lasting functional changes even when the client doesn’t recall every detail afterward.
- •Technique: treating the self with the compassion one would give a child (re-parenting)
- •Case: childhood sexual abuse survivor experiences dramatic remission of depression
- •Case: Vietnam veteran processes loss via imagery (grave + joyful birthday memory), later improves markedly
- •Hypnosis as an ‘operating system update’: new rules for agency, guilt, helplessness, and acceptance
- 1:24:31 – 1:32:42
Resistance, agency, psychedelics parallels—and why medicine sidelined hypnosis
The conversation turns to “resistance” and the stories people tell about pain, trauma, and control—connecting hypnosis to ACT-like acceptance and to psychedelic therapy themes (with different risk profiles). Spiegel closes by arguing hypnosis was marginalized due to misunderstanding, economic incentives, and medicine’s bias toward physical interventions.
- •Resistance and shame amplify suffering; hypnosis can help create helpful dissociation/perspective
- •Parallels with psychedelics/meditation: reduced default-mode activity and altered self-processing
- •Key distinction: hypnosis tends to preserve agency/control and scales safely via apps
- •Why sidelined: fear/misunderstanding, pharma marketing power, and medical preference for injections/incisions/ingestion
- 1:32:42 – 1:33:31
Closing: where to learn more and final reflections
Chris wraps with reflections on Spiegel’s calming presence and the practical potential of hypnosis for regulation and behavior change. Spiegel emphasizes hypnosis as agency-enhancing and encourages people to explore tools like Reveri responsibly.
- •Host reflection: Spiegel’s cadence and demeanor feel regulating in themselves
- •Hypnosis framed as empowerment rather than mind control
- •Encouragement to experiment—low downside if it doesn’t work
- •Episode outro and recommendation to watch another interview
