Imagine a witness taking the stand at a massive high stakes murder trial.

She points directly at the defendant and she testifies with like 100 % unshakable certainty that he is the killer.

Right.

And the jury totally believes her, you know, because her confidence is just palpable.

But what the jury doesn't know is that yesterday she had absolutely no idea who the killer was.

Oh, wow.

Yeah, she didn't know until a police detective put her into a hypnotic trance.

It sounds like a plot from a late night thriller or something, right?

But I mean, it is a very real, incredibly messy scenario that courts have been battling over for literally decades.

The question is, should that kind of testimony be legal?

And that is the exact question we are exploring today.

So welcome to this one -on -one tutoring session designed specifically for you.

Yes, you.

We know you're a college student staring down a massive forensic psychology exam.

The clock is totally ticking and you need to master chapter 20 of the Handbook of Forensic Psychology.

Right, the chapter called Applying Hypnosis in Forensic Contexts.

Exactly.

We are your guides from the last minute lecture team and we're gonna unpack this whole chapter for you today in this deep dive.

And if there's one overarching theme you really need to grasp for this exam,

it is friction.

Friction?

Yeah, like there is an immense grinding friction between the legal system and psychology.

Oh, okay.

Because the law demands black and white certainty,

guilty or not guilty,

admissible or inadmissible.

Right, the law hates gray areas.

Exactly.

But psychology, especially when you're dealing with altered states of consciousness like hypnosis, well, it operates almost entirely in the gray.

So to give you a quick roadmap of what we're covering today, we're gonna look at the regulation of hypnosis, then crimes committed under hypnosis, the battle over memory recall in court, the standard of care for therapists, and finally courtroom advocacy.

It's a lot, but we'll get through it.

We will.

So let's start with the most basic problem, right?

Before a judge can even rule on whether a hypnotized person can testify, the law has to define what hypnosis actually is.

Which is harder than it sounds.

Honestly, yeah.

Because reading the American Society of Clinical Hypnosis definition, I was, well, I was a bit confused.

How so?

Well, they claim hypnosis is built on three pillars,

dissociation, absorption, and suggestibility.

Right, the classic three.

But isn't that just like what happens when I zone out scrolling on my phone for three hours?

I mean, how is clinical hypnosis actually different from just being really, really distracted?

That is actually a fantastic distinction to make.

Zoning out on your phone definitely involves absorption.

You're hyper -focused on the screen.

Definitely.

And it involves dissociation, because you're sort of tuning out the peripheral awareness of the room around you.

You don't hear someone calling your name.

Yeah, exactly.

But the third pillar, suggestibility.

That is where clinical hypnosis diverges.

Okay, suggestibility.

Right, in a formal hypnotic state, there is a relative suspension of critical judgment.

You become profoundly open to the suggestions of the clinician.

It's a deliberate, guided alteration of consciousness.

Not just a passive distraction.

Exactly, it's active and guided.

And here's a piece of the puzzle that just totally blew my mind.

Hypnotizability isn't just an event, right?

It's an actual, measurable, psychological trait.

Oh, absolutely.

It's not something that just happens to you because someone waves a pocket watch in your face.

Right, so how do they measure it?

We measure this trait using standardized assessment instruments.

Things like the Stanford, Harvard, or Barber scales.

Okay, write those down for the exam.

Stanford, Harvard, Barber.

Good tip.

And what those scales show is that some people simply cannot be hypnotized no matter how skilled the clinician is.

A very small percentage are highly hypnotizable, and the rest of us, well, we fall somewhere on a bell curve in the middle.

So hypnosis is a consequence of that innate trait interacting with a process, not just a ceremony.

Precisely.

But historically, the courts totally ignored that science, right?

They just looked at whether the ceremony happened.

Pretty much.

Which brings up a terrifying issue.

The law regulating who is actually allowed to perform the ceremony is completely chaotic.

Oh, it's a mess.

You read this chapter and realize it's basically the Wild West.

I mean, a few states like California, Connecticut, and Florida, they have specific rules.

Everywhere else, it's totally ambiguous.

And that ambiguity has historically led to criminal charges for people treating hypnosis like a parlor trick.

Right, the chapter highlights a couple of major appellate cases that established precedent here, like Masters v.

State in 1960.

Right, where you had a lay hypnotist, meaning no medical license,

telling an undercover inspector that his physical ailments stemmed from a hatred of his father.

Just casually diagnosing that.

Exactly,

and a year later, in People v.

Cantor, another lay hypnotist was guaranteeing weight loss.

So they were basically practicing psychiatry without a degree.

That is exactly how the courts saw it.

Both of them were convicted of the unlawful practice of medicine.

Makes sense.

The courts realized that using something as powerful as hypnosis to cure psychological or medical issues without clinical training is incredibly dangerous.

I mean, you could unearth severe trauma and leave a patient far worse off.

Which isn't just theoretical.

The chapter outlines some really tragic real -world stakes here.

It does.

There's the Hohe v.

San Diego case where a high schooler was actually injured during an amateur Magic of the Mind stage show.

Right, a stage show.

But the darkest example is the case of Florida high school principal George Kenney.

Oh, that case is heartbreaking.

It really is.

He was hypnotizing his students to help them improve their test scores and athletic performance.

But he didn't have a license.

No clinical training at all.

None.

And shortly after, three of those students died, one by suicide, the very next day.

He ended up pleading no contest to practicing without a license.

It just underscores a fundamental clinical reality.

Hypnosis is not a toy.

It can fundamentally alter a person's psychological state.

So, and this is what I don't get.

If it's as powerful as a surgical tool, powerful enough to contribute to those kinds of tragedies, why does the law treat it like a massage license in some states and a medical degree in others?

That paradox is a perfect example of the legal system lagging behind clinical science.

The legal standard of care for lay hypnotists remains dangerously unresolved in so many jurisdictions.

We'll let it pivot from accidental harm to intentional control.

Okay, moving into criminal responsibility.

Because if an amateur can do that much damage, what happens when someone uses hypnosis on purpose to commit a crime?

This Bengali myth.

Yes.

The idea that a hypnotist can turn you into a mind -controlled zombie and, I don't know, force you to rob a bank.

Psychologists have been debating the reality of that concept for decades.

And for your exam, there are two main theoretical camps you need to understand here.

Okay, what's the first one?

On one side, you have state theories.

These argue that hypnosis is a genuinely altered brain state where executive control is divided or even handed over to the hypnotist.

So a real loss of control, but then you have socio -cognitive theories, right?

Which argue the exact opposite.

They say the subject doesn't actually lose executive control at all.

They just perceive the situation as if they've lost control.

Exactly, they are subconsciously acting out the role they think is expected of them.

Right, it's the difference between a literal loss of free will versus a highly complex psychological role play.

That's a great way to put it.

But no matter which psychological theory you subscribe to, this debate crashes headfirst into the courtroom when a defendant points at someone else and says, the hypnotist made me do it.

Right, and the chapter traces this hypnotic coercion defense back over a century.

Yeah, all the way to an 1894 case, People v.

Worthington.

Where a woman literally claims she murdered her lover because she was under her husband's hypnotic power.

And the court predictably did not buy it at all.

But fast forward to the 1981 case of United States v.

Phillips and things get even more theatrical.

Oh, Phillips is wild.

A woman claims she was the hypnotic slave of her husband and her husband actually took the stand and bragged about his control over her.

He really did.

He testified under oath that he had been hypnotizing her up to 15 times a day since she was a teenager.

Telling her he was her Lord and God.

Yeah, and even implanting false memories.

But here is the craziest part, despite that insane testimony,

no reported appellate case has ever successfully upheld the hypnosis defense to excuse criminal conduct.

Never.

It's an uphill battle that defendants universally lose.

Which introduces a profound contradiction in the law, I think.

How so?

Well, if you look at the Model Penal Code, which is a heavily influential document that helps standardize laws across the United States.

Very influential, yeah.

It explicitly lists conduct during hypnosis or resulting from hypnotic suggestion as an involuntary act.

Right.

Wait, I need you to explain that to me.

If the legal system's own rule book literally defines a hypnotic act as involuntary, how can judges consistently throw out that exact defense?

Isn't the law completely contradicting itself?

It absolutely is.

On paper, the law acknowledges the psychological theory that free will might be diminished under hypnosis.

But in practice,

judges and juries refuse to let violent offenders off the hook based on an invisible subjective mental state.

They prioritize public safety and accountability above all else.

Because they're afraid of the floodgates opening.

Exactly.

The fear is that if they allow the Sengali defense even once,

everyone will start claiming they were hypnotized to commit crimes.

Okay, so if claiming mind control doesn't work, the real legal battleground in forensic psychology shifts entirely to memory.

Yes, the most heavily litigated area in the whole chapter.

If a witness is hypnotized to remember the details of a crime, can they testify?

Historically, courts were incredibly skeptical of this.

I mean, as far back as the 1897 case, People V .E.

Banks, courts ruled that an expert couldn't testify about a defendant's hypnotic declaration of innocence.

Because you can't cross -examine a trans.

Precisely.

You cannot cross -examine someone while they are under hypnosis.

But then the 1970s hit, and police departments started heavily relying on hypnosis to find investigative leads.

They needed a standardized way to do it.

Which led to the FBI developing the federal model.

And for your exam, you really need to understand how this federal model works.

It's a strict two -person team approach.

Two people.

Like, good cop, bad cop.

Kind of.

You have a licensed mental health professional who conducts the actual hypnosis.

Okay.

And they are paired with a law enforcement investigator who advises on what information the police actually need.

The clinician's priority is protecting the psychological well -being of the witness while the investigator focuses purely on the facts.

But as the police began using this federal model, the courts had to figure out what to do with the testimony it produced.

Right.

And the legal system cycled through three distinct rules for admissibility.

Understanding their evolution is critical for the exam.

It started with the open admissibility rule in 1968, established by Harding v.

State.

And open admissibility basically means let the jury figure it out.

Right.

The court in Harding said a hypnotized witness can take the stand, and if their memory is flawed or bizarre, well, it's the defense lawyer's job to expose that flaw during cross -examination.

It treated hypnosis just like drinking a cup of coffee to jog your memory.

But treating hypnosis so casually horrified the defense bar, didn't it?

Oh, and much of the scientific community, too.

It sparked a massive legal backlash that created the second rule, per se, exclusion.

This began with cases like State v.

Mack and the incredibly influential California case People v.

Shirley.

Let's really dig into People v.

Shirley because this wasn't just a slight adjustment.

It was a total ban.

It was a complete ban.

These courts applied what's known as the Frye standard.

The Frye standard.

Right.

It asked the sensible question, is a scientific technique generally accepted by the relevant scientific community?

And the courts looked around, saw a lot of debate among psychologists, and determined hypnotically refreshed memory was not generally accepted as reliable.

Exactly.

And the primary psychological fear driving this ban was something called memory hardening.

Memory hardening.

Yeah.

Which is terrifying from a legal perspective.

It's completely terrifying.

The fear is that during hypnosis, a witness might create a false memory, maybe because the police asked a leading question.

Like, was the car red?

Yes.

And because of the deeply relaxed, suggestible state of the trance, the witness adopts that false memory as absolute truth.

When they wake up, they are 100 % confident in something that never actually happened.

And if a witness genuinely believes their own lie with unshakable confidence, the defense lawyer can't break them on cross -examination.

Right, you can't catch someone in a lie if they think they're telling the truth.

So the foundation of a fair trial, the ability to cross -examine is destroyed.

If hypnosis destroys that ability through memory hardening, the court's reasoned, the evidence must be banned entirely.

So under the per se exclusion rule, if you remember something during or after hypnosis, you are forbidden from testifying about it.

Wow.

So the per se rule is essentially saying that if a detective uses a dirty magnifying glass to look at a piece of evidence, we don't just clean the glass or warn the jury, we throw out the evidence entirely, even if it's the only clue we have.

That is a brilliant analogy.

And because throwing out the only clue is such an extreme consequence, courts eventually sought a middle ground.

Which brings us to the third rule guidelines, or the Totality of the Circumstances Test.

Right, cases like State v.

Heard and State v.

Armstrong.

They basically said, we will admit the testimony, but only if you follow rigorous, mandatory safeguards.

Safeguards like the hypnotist must be an independent licensed professional, not a police officer.

Every single interaction must be videotaped.

You have to get a detailed record of what the witness remembers before the trance even begins.

And importantly, the judge holds a pre -trial hearing to evaluate if the process was overly suggestive.

But we have to introduce a massive constitutional curve ball here.

Everything we just discussed applies to witnesses and victims, but what if the person who wants to be hypnotized is the defendant?

Ah, this is where Rog v.

Arkansas in 1987 changes everything.

This case is fascinating.

A woman shot her husband during a physical altercation, but because of the trauma, she couldn't remember the exact moment the gun went off.

She underwent hypnosis and suddenly remembered that her finger wasn't even on the trigger.

Later, forensic experts proved the gun was actually defective and could fire without the trigger being pulled.

But Arkansas had a strict per se exclusion rule.

Yeah, so they barred her from testifying about her own memory.

And the US Supreme Court struck that down.

They ruled that a defendant's Sixth Amendment right to testify in their own defense completely overrules a state's evidentiary per se ban.

You simply cannot categorically silence a defendant.

Furthermore, the legal landscape shifted when the Daubert standard replaced the old Frey standard.

Right, the Daubert standard is crucial for the exam.

Instead of just counting noses to see if a science is generally accepted,

Daubert forces judges to act as scientific gatekeepers.

They have to look at error rates, peer -reviewed research, and the specific methods used.

Under Daubert, rigid, inflexible per se bans are much harder to defend.

But we also have to remember that while defendants have the right to use hypnosis, they're also deeply vulnerable to it.

Extremely vulnerable.

Look at the case of Lara Villeneuve.

A police doctor offered to treat a murder suspect's severe sinus headache,

covertly put him into a hypnotic trance, and psychologically coerced a confession out of him.

It proves that defendants desperately need constitutional protection from the misuse of altered states.

So we've spent all this time talking about what judges and lawyers are terrified of, right?

Memory -hardening, pseudo -memories, confabulation.

All fears.

But what does the actual psychological research say?

Are the court's fears scientifically valid?

Well, the science is far more nuanced than the law wants to admit.

First, we run into the problem of ecological validity.

Ecological validity.

Which means it is practically impossible to perfectly study trauma and memory in a laboratory setting.

Right, you cannot ethically rob a group of college students at gunpoint to see how well they remember the face of the attacker under hypnosis.

Right.

Watching a video of a crime in a safe lab is fundamentally different from experiencing a violent threat to your life.

Exactly.

But the research we do have shows that phenomena like confabulation, which is your brain filling in memory gaps with imaginary details and pseudo -memories, are not exclusive to hypnosis.

They are natural flaws of everyday human memory.

Our memory is reconstructive.

It's not a video recording, you can just rewind.

And this is why those standardized assessment procedures we mentioned earlier are so critical.

Research indicates that the creation of false memories isn't usually caused by the hypnotic ceremony itself.

Okay, so what causes it?

It is heavily tied to two factors.

The subject's natural high hypnotizability trait and the interviewer's use of leading questions.

Hold on, wait.

If the science shows that a highly hypnotizable person is just as likely to form a false memory from a leading police question without hypnosis as they are with hypnosis, aren't the courts completely scapegoating hypnosis?

Yes.

They ban the trance, but ignore the real problem of terrible police interviewing.

That is precisely the argument made by leading memory researchers and the American Society of Clinical Hypnosis, the ASCH.

In the 1980s, the American Medical Association issued reports relying on laboratory research that supported the courts leaning toward per se bans.

But the ASCH vehemently disagreed.

They argued that a suggestive, aggressive police interrogation without hypnosis is actually far more dangerous than formal clinical hypnosis.

So a strict per se ban might eliminate all false memories.

Sure.

But it also eliminates all the true corroborated memories retrieved through careful protocols.

It trades actual justice for judicial convenience.

It really does.

And those strict courtroom rules are now causing severe collateral damage, bleeding backward into the clinical therapist's office.

Because of therapist liability.

Right.

Imagine a therapist is treating a trauma survivor.

They use hypnosis purely for therapeutic healing to help the patient process their emotions with zero intention of legal memory retrieval.

But if that patient later decides they want to sue their abuser and they live in a state with a per se exclusion rule, the fact that they were hypnotized might completely disqualify them from ever testifying.

The therapist, in trying to heal the patient,

accidentally ruined their day in court.

And that patient might turn around and sue the therapist for malpractice.

This is exactly why the chapter hammers home the necessity of rigorous informed consent.

Before using hypnosis, a therapist must warn the patient, often in writing, that the treatment might jeopardize their future legal rights.

Because defense lawyers are constantly weaponizing the Daubert standard in civil suits, trying to paint hypnosis as a dangerous and experimental treatment just to discredit victims.

It's fascinating and a bit terrifying how frenzied psychology is used as a legal weapon.

But speaking of lawyers weaponizing psychology, we have to talk about the wildest part of the chapter courtroom advocacy.

The idea of lawyers themselves using hypnosis.

It sounds like pure fiction, but it's a real historical phenomenon.

Starting in the mid 20th century, figures like Dr.

William Bryan began teaching hypnotic persuasion techniques directly to trial lawyers.

Right, famous powerhouse attorneys like Melvin Belli and F.

Lee Bailey studied these methods.

Bailey actually graduated from Bryan's advanced hypnosis class.

It got so intense that it led to this incredibly absurd 1939 case, Wilburn v.

Reitman.

Oh, this case is hilarious.

An attorney literally accused the opposing counsel of hypnotizing the judge to win the case.

I mean, can you imagine standing up in court and objecting because the other lawyer is using mind control on the bench?

The chief justice actually had to formally state for the record that practicing hypnotism in a court of justice is not permitted.

Unbelievable.

Now, of course, ethical codes today strictly prohibit teaching formal trans -inductions to lawyers.

Yeah, you cannot purposefully try to put the jury or the judge to sleep.

However, the psychological principles underlying hypnosis, assessing the suggestibility of an audience, using pacing and powerful metaphors, hyper -focusing attention, lowering critical thinking, those are perfectly legal.

In fact, they are everyday courtroom tools.

When you lay out those skills, assessing suggestibility, using sensory language, building unconscious associations that literally just sounds like the job description of a world -class trial lawyer, is a great closing argument, really just a legally sanctioned hypnotic induction.

Well, if you define hypnosis broadly as a form of persuasive communication designed to alter peripheral awareness and focus concentration,

then the line between a brilliant orator and a hypnotic influencer is remarkably thin.

Okay, we have covered a massive amount of ground today.

To synthesize all of this for your exam, how should we pull this together?

Think back to the concept of friction.

Forensic psychology acts as a bridge.

It is constantly trying to translate the highly subjective, deeply variable nature of human consciousness into the rigid binary rules of the legal system.

Right, clinical reality embraces nuance, individual traits, and gray areas.

But legal admissibility demands standardization and broad sweeping rules like per se bans, even if those rules sometimes fail the actual science.

You cannot cleanly x -ray the human mind.

The law wants a broken or unbroken bone, but psychology gives it a complex web of memory and perception.

Which leaves us with a truly fascinating question for the future.

As neuroscience and brain imaging technology advance, what happens when we can finally see a state of hypnosis?

Oh, wow.

What happens when a false memory literally lights up differently on an fMRI scan than a true memory?

Will the courts be forced to throw out all these 20th century precedents, like Shirley and Herd, and rewrite the rules of witness testimony entirely from scratch?

That is a brilliant and honestly wild thought to chew on.

What happens when the invisible becomes visible?

It changes everything.

And with that, you have officially conquered chapter 20.

You know the legal standards, you understand the psychological theories, and you are ready for the courtroom battles.

You're gonna ace this exam.

From the Last Minute Lecture team, thank you for listening, and good luck.
