A hypnotizability test measures how strongly you respond to suggestions once you are in hypnosis. Clinicians use standardized scales such as the Stanford Hypnotic Susceptibility Scale, the Harvard Group Scale, Spiegel's Hypnotic Induction Profile and the Elkins Hypnotizability Scale, and the free quiz below is a home version built on the same ideas.
"How hypnotizable am I?" is one of the most common questions people ask before trying hypnotherapy. Usually it is a polite way of asking something more anxious: what if I'm the person it doesn't work on?
I'm Paola Mendez, certified RTT (Rapid Transformational Therapy) hypnotherapist, trained under the method developed by Marisa Peer, and the founder of Mochi Zen. In this post I'll walk you through the tests researchers and doctors actually use, give you a quiz you can take right now, and then show you what the research says your score does and does not predict. The short version: your score is real, but it matters a lot less than most people fear.
Whatever your score, Mochi Zen's RTT-based sessions give your mind daily practice going into the hypnotic state, aimed at cravings, anxiety, sleep or burnout. Try it free for 7 days.

The quiz has 10 questions. Six ask about how you experience everyday life, and four are short try-it-yourself exercises modeled on items from the clinical scales. Do the exercises for real, sitting somewhere quiet: answering from memory gives you a much less useful score. You'll get a score out of 20 and the "channel" you respond through most strongly.
This quiz is an informal self-assessment for curiosity and self-understanding. It is not a validated clinical instrument and not a diagnosis. Health note: if you have epilepsy or a seizure disorder, skip the two eye exercises (questions 5 and 6). Prefer a full-screen version to share? Use the standalone hypnotizability quiz.

What Is Hypnotizability?
Hypnotizability (researchers also call it hypnotic susceptibility or hypnotic suggestibility) is how much you respond to suggestions given during hypnosis. A suggestion is an invitation to experience something as real: your arm getting heavy, your hands drifting together, a taste you imagine. Highly hypnotizable people experience those things vividly and without effort. Less hypnotizable people mostly experience them as ideas.
Three findings make it worth taking seriously as a trait:
- It is remarkably stable. Stanford researchers retested the same people over decades and found scores correlated at r = .71 across 25 years, with a median change of just one point on a 12-point scale (Piccione, Hilgard & Zimbardo, 1989).
- It shows up in the brain. In a Stanford imaging study, highly hypnotizable adults showed stronger functional connectivity between the left dorsolateral prefrontal cortex (planning and control) and the salience network (which flags what matters) than low scorers did, with no structural brain differences (Hoeft et al., 2012).
- It travels with "absorption." People who get deeply lost in music, films, nature or their own imagination tend to score higher. Tellegen and Atkinson named this "openness to absorbing and self-altering experiences" in 1974, describing it as a trait related to hypnotic susceptibility.
What hypnotizability is not: it is not gullibility, weakness, low intelligence or a lack of willpower. Those myths are worth clearing out before you look at your score; I cover the most common ones in the biggest myths about hypnosis. You never lose control in hypnosis, and a high score simply means your imagination and your body talk to each other easily.
How Do Doctors Measure Hypnotizability?
In research and clinical settings, hypnotizability is measured with standardized scales. Each one follows the same basic recipe: a hypnotic induction, then a series of suggestions that get progressively harder, then a count of how many you passed. Here are the ones you'll see referenced most:
| Scale | Format | What it involves |
|---|---|---|
| Stanford Hypnotic Susceptibility Scale, Form C (SHSS:C) | One-on-one with a trained examiner | 12 suggestions in order of increasing difficulty, from arm movement to hallucinations and amnesia. Widely treated as the research gold standard (described here). |
| Harvard Group Scale (HGSHS:A) | Groups, from a recording | 12 suggestions such as eye closure, hands moving together and arm immobilization. Commonly scored 0 to 11. |
| Hypnotic Induction Profile (HIP) | Short clinical test | Developed by psychiatrist Herbert Spiegel and refined with his son David Spiegel at Stanford. Includes the famous "eye-roll" sign and an arm-levitation suggestion, scored 0 to 10 (Faerman & Spiegel, 2021). |
| Elkins Hypnotizability Scale (EHS) | One-on-one, clinic-friendly | Designed to be gentler and more clinically practical. Correlated .86 with the Stanford Form C in validation (Kekecs et al., 2016). |
| Tellegen Absorption Scale (TAS) | Self-report questionnaire | Not a hypnosis test itself, but measures the absorption trait that tends to accompany high hypnotizability. |
The scales agree with each other reasonably well rather than perfectly. For example, the HIP correlated r = .66 with the Stanford Form C in a cross-validation sample, about the same as the Harvard Group Scale's correlation with it (Frischholz et al., 2015). Even the professional tests are estimates, which is a useful thing to remember when you look at any single score.
What is the hypnosis eye-roll test?
The eye-roll sign is the best-known piece of the Hypnotic Induction Profile: you look up as far as you can, then slowly close your eyelids while still looking up, and the examiner rates how much of the colored part of your eye disappears. Herbert Spiegel proposed it in 1972 as a quick marker of hypnotic capacity. On its own it is only a rough signal, which is why it is one question in the quiz, not the whole test. If you have epilepsy or a seizure disorder, skip the eye-roll and the heavy-eyelid exercise: rolling the eyes upward while closing the eyelids can trigger seizures in some forms of epilepsy. Both are optional in the quiz.
How Does This Free Hypnotizability Quiz Work?
A real clinical scale needs a trained examiner and a full induction, so no website can give you an SHSS:C score. The quiz borrows the ingredients those scales are made of instead:
- Absorption questions (getting lost in a movie, zoning out on a familiar drive) echo the Tellegen Absorption Scale.
- Imagery questions (the lemon, vivid childhood pretend play) tap imaginative involvement.
- Body-response exercises (magnetic hands, the heavy arm, heavy eyelids) are home versions of the easiest motor items on the Harvard and Stanford scales, plus the HIP eye-roll.
- Your attitude toward hypnosis counts because expectation genuinely shapes how people respond.
Each answer scores 0 to 2 points, for a total out of 20, and the quiz names your strongest channel: imagination, absorption or body response.
What Does Your Hypnotizability Score Mean?
High (15 to 20). Suggestions feel real to you, often quickly. You likely get deeply absorbed in experiences and notice physical responses to imagined ones. Hypnosis recordings tend to "land" for you from the first sessions.
Moderate (8 to 14). Some suggestions took hold and some didn't. This is the most common result, and it is where most people land on the clinical scales too. People in this range usually find the hypnotic state deepens noticeably with familiarity: the same voice, the same induction, a regular time.
Low (0 to 7). You stayed mostly in observer mode. That's often a sign of an analytical, monitoring mind, or simply skepticism about the process. It is not a sign that hypnosis is useless for you (see the next two sections).
If you scored low or moderate, your hypnotizability can improve with training and practice: in lab studies, over half of low scorers and over two-thirds of medium scorers tested high after hypnotic skills training. Mochi Zen's daily RTT-based sessions are built for that kind of practice, and I explain the research in can you become more hypnotizable?
How common is each result? It depends on the scale and who is tested. A 2024 analysis pooled 15 studies using the Harvard Group Scale (1,963 people, mostly student volunteers) and found 12.2% scored low, 56.8% medium and 31.0% high, with the individual studies varying widely (Zech et al., 2024). In other words: most people sit in the middle, and true non-responders are a small minority.
Moderate is the most common score, and it's the range where daily practice makes the biggest difference. Mochi Zen's RTT-based sessions use the same calm induction every day so going under gets easier.

Less than you'd think, and this is the most reassuring part of the research. A meta-analysis that pooled studies of hypnosis for pain found the link between hypnotizability and how much pain relief people got was r = .24: hypnotizability explained only about 6% of the difference in outcomes. The authors went as far as questioning whether it is useful to measure hypnotic suggestibility in clinical settings at all (Montgomery, Schnur & David, 2011).
So what does matter? Research by Irving Kirsch and colleagues found that how people respond to suggestion is shaped heavily by what they expect and how motivated they are. In one study, nonhypnotic suggestibility, motivation and expectancy together explained 53% of the variance in how people responded behaviorally to suggestions (Braffman & Kirsch, 1999). That's good news, because expectation and motivation are things you can work with. Clear explanations, a voice you trust and repeated sessions all move them.
This lines up with what clinical reviews have found about hypnosis recordings: how the program is used (consistency, the right goal, real-life practice) predicts results better than a person's trait score. I unpack that in do hypnosis recordings work? For a plain-language overview of what clinical hypnosis is used for, see the Mayo Clinic's guide to hypnosis.
What If You Scored Low on the Hypnotizability Test?
A low score on a home quiz is a reading from one afternoon, not a lifelong label. Researchers have spent decades testing whether hypnotic responsiveness can be trained, and some training programs moved a large share of low scorers into the high range, although other labs found smaller and shorter-lived gains. I go through that research, honestly, in can you become more hypnotizable?
For a broader look at whether there is really such a thing as an "unhypnotizable" person, my practice blog covers whether everyone can be hypnotized. And if you're curious how your hypnotizability relates to your everyday responsiveness to ideas, take the companion suggestibility test: the two are related, but not the same thing.
If you want a personal assessment rather than a quiz, a qualified hypnotherapist can take you through a full induction and see how you respond. I work with private clients through Pao Hypnosis in Miami and remotely, and RTT sessions are designed to work across the whole range of hypnotizability, not only for high scorers.
Your hypnotizability score describes today, not your potential. Mochi Zen's RTT-based programs turn practice into a daily habit, one short session at a time.

How do I know if I am hypnotizable?
The only precise way is a standardized scale, like the Stanford, Harvard, Spiegel or Elkins scale, given by a trained examiner. For a quick home estimate, take a quiz that combines absorption questions with simple exercises like magnetic hands and the heavy arm. If those exercises produced any real physical response, you are hypnotizable to at least some degree.
What percentage of people are highly hypnotizable?
It depends on the scale and the sample. A 2024 analysis of 15 Harvard Group Scale studies (1,963 people, mostly students) found about 31% scored high, 57% medium and 12% low. Most people sit in the middle range, and people who are truly unresponsive to suggestion are a small minority.
Can you be immune to hypnosis?
Very few people show no response at all on the clinical scales, and a low score usually reflects an analytical, observing style or skepticism rather than immunity. Hypnotizability also explains only a small part of whether hypnosis helps someone. Expectation, motivation and practice play a larger role than most people assume.
What is the hypnosis eye-roll test?
It is part of the Hypnotic Induction Profile developed by Herbert and David Spiegel. You look up as far as you can, then slowly close your eyelids while still looking up, and the examiner rates how much of the iris disappears. More white suggests more hypnotic capacity, but it is a rough signal, not a full test.
Is hypnotizability linked to intelligence or being gullible?
No. Hypnotizability is related to absorption and imaginative involvement: the ability to get deeply engaged in an experience. It is not a measure of intelligence, weakness or gullibility. Brain imaging shows highly hypnotizable people differ in how attention and control networks communicate, not in brain structure.
Does hypnotizability change over time?
For most people it is very stable. A Stanford follow-up found scores correlated .71 across 25 years, with a median shift of one point. Some training studies did raise scores, and a 2024 brain-stimulation trial produced a temporary increase, but for everyday purposes practice and expectation matter more than your trait score.
Does a low hypnotizability score mean hypnotherapy won't work for me?
Not necessarily. A meta-analysis found hypnotizability explained only about 6% of the variation in how much people benefited from hypnosis for pain. Regular practice, clear expectations and a session that targets the right problem tend to matter more than whether you scored low, moderate or high.
