For decades, one of the biggest limitations of hypnotherapy has been a simple biological reality: not everyone responds to hypnosis equally. Around a third of adults show very low hypnotizability — meaning that no matter how skilled the therapist, the depth of trance they can achieve is limited. But a landmark 2024 study from Stanford University, published in the prestigious journal Nature Mental Health, has changed what we thought was possible.
What the Study Found
Researchers at Stanford Medicine led by Dr Afik Faerman and senior author Dr David Spiegel — one of the world's foremost hypnosis scientists — demonstrated for the first time that hypnotizability can be temporarily increased using targeted electrical brain stimulation.
Using transcranial magnetic stimulation (TMS) directed at a precise brain region, participants who were previously considered low-hypnotizability showed significantly elevated responsiveness to hypnosis — for approximately one hour following stimulation. The effect was repeatable and measurable on standard hypnotizability scales.
The study found that less than two minutes of focused electrical stimulation was enough to produce this window of heightened receptivity. For participants in pain management trials, this translated into meaningfully improved outcomes during hypnotic analgesia sessions.
The Brain Regions Behind the Breakthrough
The finding builds on earlier Stanford neuroimaging work that identified a specific neural signature in highly hypnotisable people: stronger functional connectivity between the left dorsolateral prefrontal cortex (involved in focused attention and decision-making) and the dorsal anterior cingulate cortex (involved in filtering out distraction).
In short, highly hypnotizable people have a brain that is naturally better at entering a state of concentrated, distraction-free focus. The TMS study effectively mimicked this connectivity pattern — temporarily giving lower-hypnotizability participants access to a brain state they do not typically reach on their own.
"Hypnosis is a state of highly focused attention, and higher hypnotizability improves the odds of your doing better with techniques using hypnosis," Dr Spiegel told Stanford Medicine News. "It's because you're coordinating what you are focusing on with the system that distracts you."
Why This Matters for Hypnotherapy
This research matters enormously — not just as a scientific curiosity, but as a signal of how mainstream medicine is beginning to view hypnotherapy.
The fact that a team at Stanford would invest in understanding the neurological barriers to hypnosis — and then find a way to remove them — reflects growing clinical confidence in hypnotherapy as a genuine treatment option. Pain management is the immediate application: hypnotic analgesia is already used in surgical settings, burn units, and chronic pain clinics. A technique that makes it accessible to more patients is significant.
Beyond pain, this research opens a door. If hypnotizability is a variable rather than a fixed ceiling, then the roughly one in three adults who have previously had limited results with hypnotherapy may one day have improved access to its benefits — whether for anxiety, sleep, smoking cessation, or stress reduction.
What About Those Without Access to TMS?
TMS machines are expensive medical devices. The Stanford study is a research breakthrough, not a consumer product. But there is an important takeaway for anyone interested in hypnotherapy right now: practice and consistency deepen hypnotic responsiveness over time.
Dr Spiegel and his team have consistently found that repeated exposure to self-hypnosis strengthens the neural pathways associated with focused attention. The brain is neuroplastic — and the more you practise entering a calm, focused, receptive state, the easier it becomes. This is precisely why guided hypnotherapy apps like Clear Minds are built around daily use, not one-off sessions.
How Clear Minds Supports Your Brain's Natural Hypnotic Potential
The Clear Minds app is designed around exactly this principle: that consistent, guided practice builds the kind of focused mental state the Stanford team identified as the hallmark of effective hypnosis.
Each session in the app is built to help you:
- Quiet the distracting noise of the default mode network — the mental chatter that pulls you out of focus
- Deepen your ability to enter a calm, receptive state with each session
- Apply hypnotic suggestion progressively — for sleep, anxiety, confidence, and habit change
You do not need a TMS machine to access better hypnotic depth. You need repetition, the right guidance, and a consistent environment for practice. That is what Clear Minds is built to provide.
The Stanford research is a glimpse of where clinical hypnotherapy is heading. For now, the most practical tool you have is the one in your pocket.
