Transcripts

I'd like to tell you about a legal case

that I worked on involving a man named

Steve Titus Titus was a restaurant

manager he was 31 years old he lived in

Seattle Washington

he was engaged to Gretchen about to be

married she was the love of his life and

one night the couple went out for a

romantic restaurant meal they were on

their way home and they were pulled over

by a police officer you see Titus's car

sort of resembled a car that was driven

earlier in the evening by a man who

raped a female hitchhiker and Titus kind

of resembled that rapist so the police

took the picture of Titus they put it in

a photo lineup they later showed it to

the victim and she pointed to Titus's

photo she said that one's the closest

the police and the prosecution proceeded

with a trial and when Steve Titus was

put on trial for rape

the rape victim got on the stand and

said I'm absolutely positive that's the

man and Titus was convicted he

proclaimed his innocence his family

screamed at the jury his fiance

collapsed on the floor sobbing and Titus

is taken away to jail so what would you

do at this point what would you do well

Titus lost complete faith in the legal

system and yet he got an idea he called

up the local newspaper he got the

interest of an investigative journalist

and that journalist

actually found the real rapist a man who

ultimately confessed to this rape a man

who was thought to have committed 50

rapes in that area and when this

information was given to the judge the

judge said Titus free and really that

that's where this case should have ended

it should have been over Titus should

have thought of this as a horrible year

a year of accusation and trial but over

it didn't end that way

Titus was so bitter he'd lost his job he

couldn't get it back

he lost his fiancee she couldn't put up

with his persistent anger he lost his

entire savings and so he decided to file

a lawsuit against the police and others

whom he felt were responsible for his

suffering and that's when I really

started working on this case trying to

figure out how did that victim go from

that one's the closest to I'm absolutely

positive that's the guy well Titus was

consumed with his civil case as he spent

every waking moment thinking about it

and just days before he was to have his

day in court he woke up in the morning

doubled over in pain and died of a

stress-related heart attack he was 35

years old so I was asked to work on

Titus's case because I'm a psychological

scientists I study memory

I've studied memory for decades and if I

meet somebody on an airplane this

happened on the way over to Scotland if

I meet somebody on an airplane and we

ask each other what do you do what are

you doing I say I study memory they

usually want to tell me how they have

trouble remembering names or they've got

a relative who's got Alzheimer's or some

kind of memory problem but but I have to

tell them I don't study when people

forget I study the opposite when they

remember when they remember things that

didn't happen or remember things that

were different from the way they really

were I study false memories unhappily

Steve Titus is not the only person to be

convicted based on somebody's false

memory in one project in the United

States information has been gathered on

300 innocent people 300 defendants who

were convicted of crimes they didn't do

they spent 10 20 30 years in prison for

these crimes and now DNA testing has

proven that they're actually innocent

and when those cases have been analyzed

3/4 of them are due to faulty memory

faulty eyewitness memory

well why like the jurors who convicted

those innocent people and the jurors who

convicted Titus many people believe that

that memory works like a recording

device you just record the information

then you call it up and play it back

when you want to answer questions or

identify images but decades of work and

psychology has shown that this just

isn't true

our memories are constructive their

reconstructive memory works a little bit

more like a Wikipedia page you can go in

there and change it but so can other

people I first started studying this

constructive memory process in the 1970s

I did my experiments that involves

showing people simulated crimes and

accidents and asking them questions

about what they remember in one study we

showed people a simulated accident and

we asked people how fast were the cars

going when they hit each other and we

asked other people how fast were the

cars going when they smashed into each

other and if we asked the leading smash

question the witnesses told us the cars

were going faster and moreover that

leading smashed question caused people

to be more likely to tell us that they

saw a broken glass in the accident scene

when there wasn't any broken glass at

all in another study we showed a

simulated accident where a car went

through an intersection with a stop sign

and if we asked a question that

insinuated it was a yield sign many

witnesses told us they remember seeing a

yield sign

at the intersection not a stop sign and

you might be thinking well you know

these are filmed events they're not

particularly stressful

with the same kind of mistakes be made

with a really stressful event in the

study we published just a few months ago

we have an answer to this question

because what was unusual about this

study is we arranged for people to have

a very stressful experience the subjects

in the study were members of the US

military who were undergoing a harrowing

training exercise to teach them what

it's going to be like for them if they

are ever captured as prisoners of war

and as part of this training exercise

these soldiers are interrogated in an

aggressive hostile physically abusive

fashion for 30 minutes and later on they

have to try to identify the person who

conducted that interrogation and when we

feed them suggestive information that

insinuates it's a different person many

of them miss identify their interrogator

often identifying someone who doesn't

even remotely resemble the real

interrogator and so what these studies

are showing is that when you feed people

misinformation about some experience

that they may have had you can distort

or contaminate or change their memory

well out there in the real world

misinformation is everywhere we get

misinformation not only if we're

questioned in a leading way but if we

talk to other witnesses who might

consciously or inadvertently feed us

some erroneous information or if we see

a media coverage about some event we

might have experienced all of these

provide the opportunity for this kind of

contamination of our memory in the 1990s

we began to see an even more extreme

kind of memory problem some patients

were going into therapy with one problem

maybe they had depression eating

disorder and they were coming out of

therapy with a different problem

extreme memories for horrific

brutalization sometimes in satanic

rituals sometimes involving really

bizarre and unusual elements one woman

came out of psychotherapy believing that

she endured years of ritualistic abuse

where she was forced into a pregnancy

and that the baby was cut from her belly

but there were no physical scars or any

kind of physical evidence that could

have supported her story and when I

began looking into these cases I was

wondering where do these bizarre

memories come from and what I found is

that most of these situations involved

some particular form of psychotherapy

and so I asked where some of the things

going on in this psychotherapy like the

imagination exercises or dream

interpretation or in some cases hypnosis

or in some cases exposure to false

information were these leading these

patients to develop these very bizarre

unlikely memories and I designed some

experiments to try to study the

processes that were being used in this

psychotherapy so I could study the

development of these very rich false

memories in one of the first studies we

did we use suggestion a method inspired

by the psychotherapy we saw in these

cases we use this kind of suggestion and

planted a false memory that when you

were a kid five or six years old you

were lost in a shopping mall you were

frightened you were crying you were

ultimately rescued by an elderly person

and reunited with the family and we

succeeded in planting this memory in the

minds of about a quarter of our subjects

and you might be thinking well that's

not particularly stressful but we and

other investigators have planted rich

false memories of things that were much

more unusual and much more stressful so

in a study done in Tennessee

researchers planted the false memory

that when you were a kid you nearly

drowned and had to be rescued by a

lifeguard and in a study done in Canada

researchers planted the false memory

that when you were a kid something as

awful as being attacked by a vicious

animal happened to you

succeeding with about half of their

subjects and in a study done in Italy

researchers planted the false memory

when you were a kid you witnessed

demonic possession I do want to add that

it might seem like we are traumatizing

these experimental subjects in the name

of science but our studies have gone

through thorough evaluation by research

ethics boards that have made the

decision that the temporary discomfort

that some of these subjects might

experience in these studies is

outweighed by the importance of this

problem for understanding memory

processes and the abuse of memory that

is going on in some places in the world

well to my surprise when I published

this work and began to speak out against

this particular brand of psychotherapy

it created some pretty bad problems for

me hostilities primarily from the

repressed memory therapists who felt

under attack and by the patient's whom

they had influenced I had sometimes

armed guards at speeches that I was

invited to give people trying to drum up

letter-writing campaigns to get me fired

but probably the worst was I suspected

that a woman was innocent of abuse that

was being claimed by her grown daughter

she accused her mother of sexual abuse

based on a repressed memory and this

accusing daughter had actually allowed

her story to be filmed and presented in

public places I was suspicious of this

story and so I started to investigate

and eventually found information that

convinced me

that this mother was innocent I

published an expose on the case and a

little while later the accusing daughter

filed a lawsuit even though I'd never

mentioned her name she sued me for

defamation and invasion of privacy and I

went through nearly five years of

dealing with this messy unpleasant

litigation but but finally finally it

was over and I could really get back to

my work in the process however I became

part of a disturbing trend in America

where scientists are being sued for

simply speaking out on matters of great

public controversy when I got back to my

work I asked this question if I plant a

false memory in your mind does it have

repercussions does it affect your later

thoughts your later behaviors our first

study planted a false memory that you

got sick as a child eating certain foods

hard-boiled eggs dill pickles strawberry

ice cream and we found that once we

planted this false memory people didn't

want to eat the foods as much at an

outdoor picnic the false memories aren't

necessarily bad or unpleasant if we

planted a warm fuzzy memory involving a

healthy food like asparagus we could get

people to want to eat experice more and

so what these studies are showing is

that you can plant false memories and

they have repercussions that affect

behavior long after the memories take

hold well along with this ability to

plant memories and control behavior

obviously comes some important ethical

issues like when should we use this mind

technology and should we ever ban its

use therapists can't ethically plant

false memories in the mind of their

patients even if it would help the

patient but there's nothing to stop a

parent from trying this out on their

overweight or obese teenager and when I

suggested this publicly

it created outcry again there she goes

she's advocating the parents

light of their children hello Santa

Claus I mean another way to well another

way to think about this is which would

you rather have a kid with obesity

diabetes shortened lifespan all the

things that go with it or a kid with one

little extra bit of false memory I know

what I would choose for a kid of mine

but maybe my work has made me different

from most people most people cherish

their memories know that they represent

their identity who they are where they

came from and I appreciate that I feel

that way too but I know from my work

how much fiction is already in there if

I've learned anything from these decades

of working on these problems it's this

just because somebody tells you

something and they say it with

confidence just because they say it with

lots of detail just because they express

emotion when they say it it doesn't mean

that it really happened

we can't reliably distinguish true

memories from false memories we need

independent corroboration such a

discovery has made me more tolerant of

them every day memory mistakes that my

friends and family members make such a

discovery might have saved Steve Titus

the man whose whole future was snatched

away by a false memory but meanwhile we

should all keep in mind we do well to

that memory like Liberty is a fragile

thing thank you thank you

thanks very much
