00:12
I'd like to tell you about a legal case that I worked on
0
12509
4332
Želela bih da vam ispričam o pravnom slučaju na kom sam radila,
00:16
involving a man named Steve Titus.
1
16841
3563
u kom je učestvovao čovek po imenu Stiv Tajtus.
00:20
Titus was a restaurant manager.
2
20404
3029
On je bio upravnik restorana.
00:23
He was 31 years old, he lived in Seattle, Washington,
3
23433
4090
Imao je 31 godinu, živeo u Sijetlu, država Vašington,
00:27
he was engaged to Gretchen,
4
27523
1895
bio veren devojkom Grečen,
00:29
about to be married, she was the love of his life.
5
29418
2948
trebalo je da se venčaju, bila je ljubav njegovog života.
00:32
And one night, the couple went out
6
32366
2284
Jedne večeri su izašli
00:34
for a romantic restaurant meal.
7
34650
3005
na romantičnu večeru u restoran.
00:37
They were on their way home,
8
37655
1648
Bili su na putu kući
00:39
and they were pulled over by a police officer.
9
39303
2950
i zaustavio ih je policajac.
00:42
You see, Titus' car sort of resembled
10
42253
3317
Vidite, Tajtusov auto je ličio
00:45
a car that was driven earlier in the evening
11
45570
3887
na jedan auto koji je vozio, ranije te večeri,
00:49
by a man who raped a female hitchhiker,
12
49457
3406
čovek koji je silovao jednu ženu koja je stopirala,
00:52
and Titus kind of resembled that rapist.
13
52863
3594
a Tajtus je ličio na tog čoveka.
00:56
So the police took a picture of Titus,
14
56457
2578
Policija ga je fotografisala,
00:59
they put it in a photo lineup,
15
59035
2767
stavila fotografiju u niz,
01:01
they later showed it to the victim,
16
61802
2160
pokazala ju je kasnije žrtvi
01:03
and she pointed to Titus' photo.
17
63962
2160
koja je pokazala baš tu fotografiju.
01:06
She said, "That one's the closest."
18
66122
3621
Rekla je: "Ovaj je najsličniji."
01:09
The police and the prosecution proceeded with a trial,
19
69743
3888
Policija i tužilaštvo su pokrenuli proces,
01:13
and when Steve Titus was put on trial for rape,
20
73631
3341
i kada je Stivu Tajtusu suđeno za silovanje,
01:16
the rape victim got on the stand
21
76972
2096
žrtva je svedočila
01:19
and said, "I'm absolutely positive that's the man."
22
79068
4342
i rekla: "Potpuno sam sigurna da je to taj čovek."
01:23
And Titus was convicted.
23
83410
2926
I Tajtus je osuđen.
01:26
He proclaimed his innocence,
24
86336
1974
Objavio je svoju nevinost,
01:28
his family screamed at the jury,
25
88310
2582
njegova porodica je vrištala na porotu,
01:30
his fiancée collapsed on the floor sobbing,
26
90892
2871
verenica se, jecajući, srušila na pod,
01:33
and Titus is taken away to jail.
27
93763
3395
a Tajtus je odveden u zatvor.
01:37
So what would you do at this point?
28
97158
3458
Šta biste vi uradili u tom trenutku?
01:40
What would you do?
29
100616
1636
Šta biste uradili?
01:42
Well, Titus lost complete faith in the legal system,
30
102252
3768
Pa, Tajtus je potpuno izgubio veru u pravni sistem,
01:46
and yet he got an idea.
31
106020
2032
a ipak je imao ideju.
01:48
He called up the local newspaper,
32
108052
2431
Pozvao je lokalne novine,
01:50
he got the interest of an investigative journalist,
33
110483
3387
zainteresovao jednog novinara istraživača,
01:53
and that journalist actually found the real rapist,
34
113870
4736
koji je pronašao pravog silovatelja,
01:58
a man who ultimately confessed to this rape,
35
118606
3353
čoveka koji je na kraju priznao ovo silovanje,
02:01
a man who was thought to have committed 50 rapes
36
121959
3292
čoveka za kog se smatralo da je počinio 50 silovanja
02:05
in that area,
37
125251
1332
u ovoj oblasti,
02:06
and when this information was given to the judge,
38
126583
3174
i kada su te informacije date sudiji,
02:09
the judge set Titus free.
39
129757
2936
Tajtus je bio oslobođen.
02:12
And really, that's where this case should have ended.
40
132693
4031
Stvarno, tu je slučaj trebalo da se završi.
02:16
It should have been over.
41
136724
1123
Trebalo je da se završi.
02:17
Titus should have thought of this as a horrible year,
42
137847
2520
Tajtus je trebalo da ovo smatra užasnom godinom,
02:20
a year of accusation and trial, but over.
43
140367
3836
godinom optužbi i suđenja, ali završenom.
02:24
It didn't end that way.
44
144203
2047
Nije se tako završilo.
02:26
Titus was so bitter.
45
146250
2678
Tajtus je bio toliko ogorčen.
02:28
He'd lost his job. He couldn't get it back.
46
148928
2580
Izgubio je posao, nije mogao da ga vrati.
02:31
He lost his fiancée.
47
151508
1843
Izgubio je verenicu.
02:33
She couldn't put up with his persistent anger.
48
153351
2906
Nije mogla da trpi njegov uporni bes.
02:36
He lost his entire savings,
49
156257
2146
Izgubio je celu ušteđevinu,
02:38
and so he decided to file a lawsuit
50
158403
2858
pa je odlučio da pokrene parnicu
02:41
against the police and others whom he felt
51
161261
2281
protiv policije i ostalih za koje je mislio
02:43
were responsible for his suffering.
52
163542
2319
da su odgovorni za njegovu patnju.
02:45
And that's when I really started working on this case,
53
165861
4713
Tada sam stvarno počela da radim na ovom slučaju,
02:50
trying to figure out
54
170574
1961
pokušavajući da utvrdim
02:52
how did that victim go from
55
172535
2074
kako je žrtva došla sa
02:54
"That one's the closest"
56
174609
1528
"Taj je najsličniji"
02:56
to "I'm absolutely positive that's the guy."
57
176137
4750
do "Potpuno sam sigurna da je on".
03:00
Well, Titus was consumed with his civil case.
58
180887
3279
Tajtusa je ovaj slučaj progutao.
03:04
He spent every waking moment thinking about it,
59
184166
3034
Svakog trenutka je o njemu razmišljao
03:07
and just days before he was to have his day in court,
60
187200
4151
i nekoliko dana pre suđenja,
03:11
he woke up in the morning,
61
191351
2219
probudio se ujutru,
03:13
doubled over in pain,
62
193570
1808
presavio se od bola
03:15
and died of a stress-related heart attack.
63
195378
2694
i umro od srčanog udara izazvanog stresom.
03:18
He was 35 years old.
64
198072
3187
Imao je 35 godina.
03:21
So I was asked to work on Titus' case
65
201259
4810
Pozvana sam da radim na ovom slučaju
03:26
because I'm a psychological scientist.
66
206069
2515
jer sam psiholog.
03:28
I study memory. I've studied memory for decades.
67
208584
3827
Proučavam pamćenje već decenijama.
03:32
And if I meet somebody on an airplane --
68
212411
3389
I ako upoznam nekoga u avionu -
03:35
this happened on the way over to Scotland --
69
215800
2096
ovo se desilo i na putu za Škotsku -
03:37
if I meet somebody on an airplane,
70
217896
1830
ako upoznam nekoga u avionu,
03:39
and we ask each other, "What do you do? What do you do?"
71
219726
3045
i pitamo jedno drugo: "Čime se bavite?"
03:42
and I say "I study memory,"
72
222771
1451
i kažem "Proučavam pamćenje",
03:44
they usually want to tell me how they have trouble remembering names,
73
224222
3380
oni obično žele da mi kažu kako imaju poteškoća da zapamte imena
03:47
or they've got a relative who's got Alzheimer's
74
227602
2799
ili imaju rođaka koji pati od Alchajmerove bolesti
03:50
or some kind of memory problem,
75
230416
2065
ili nekog problema sa pamćenjem,
03:52
but I have to tell them
76
232481
2216
ali moram da im kažem
03:54
I don't study when people forget.
77
234697
3505
da ne proučavam ono kad ljudi zaborave.
03:58
I study the opposite: when they remember,
78
238202
3002
Proučavam suprotno: kada se sećaju,
04:01
when they remember things that didn't happen
79
241204
2753
stvari koje se nisu desile
04:03
or remember things that were different
80
243957
1965
ili pamte stvari drugačijim
04:05
from the way they really were.
81
245922
2025
nego što su zaista bile.
04:07
I study false memories.
82
247947
4736
Proučavam lažna sećanja.
04:12
Unhappily, Steve Titus is not the only person
83
252683
4307
Nažalost, Stiv Tajtus nije jedina osoba
04:16
to be convicted based on somebody's false memory.
84
256990
4305
koja je osuđena na osnovu nečijeg lažnog sećanja.
04:21
In one project in the United States,
85
261295
3308
Jedan projekat u SAD-u
04:24
information has been gathered
86
264603
2252
prikupio je informacije
04:26
on 300 innocent people,
87
266855
3934
o 300 nevinih ljudi,
04:30
300 defendants who were convicted of crimes they didn't do.
88
270789
3895
300 osuđenih za zločine koje nisu počinili.
04:34
They spent 10, 20, 30 years in prison for these crimes,
89
274684
5300
Proveli su 10, 20, 30 godina u zatvoru za ove zločine,
04:39
and now DNA testing has proven
90
279984
2427
i onda je DNK testiranje dokazalo
04:42
that they are actually innocent.
91
282411
2916
da su u stvari nevini.
04:45
And when those cases have been analyzed,
92
285327
2521
Kada su ti slučajevi analizirani,
04:47
three quarters of them
93
287848
2141
tri četvrtine njih
04:49
are due to faulty memory, faulty eyewitness memory.
94
289989
5611
nastalo je zbog netačnog pamćenja, netačnog pamćenja svedoka.
04:55
Well, why?
95
295600
1263
Dakle, zašto?
04:56
Like the jurors who convicted those innocent people
96
296863
3451
Kao porotnici koji su osudili te nevine ljude,
05:00
and the jurors who convicted Titus,
97
300314
2284
kao i porotnici koji su osudili Tajtusa,
05:02
many people believe that memory
98
302598
2241
mnogi ljudi veruju da pamćenje
05:04
works like a recording device.
99
304839
1647
radi kao uređaj za snimanje.
05:06
You just record the information,
100
306486
2257
Samo snimite informacije,
05:08
then you call it up and play it back
101
308743
2647
potom ih prizovete i pustite
05:11
when you want to answer questions or identify images.
102
311390
3427
kada želite da odgovorite na pitanja ili identifikujete slike.
05:14
But decades of work in psychology
103
314817
2163
Ali decenije rada u psihologiji
05:16
has shown that this just isn't true.
104
316980
3153
pokazuju da ovo nije istina.
05:20
Our memories are constructive.
105
320133
2430
Naša sećanja su konstruktivna.
05:22
They're reconstructive.
106
322563
1569
I rekonstruktivna.
05:24
Memory works a little bit more like a Wikipedia page:
107
324132
3481
Pamćenje pre funkcioniše kao stranica Vikipedije:
05:27
You can go in there and change it, but so can other people.
108
327613
5113
možete mu pristupiti i promeniti ga, ali to mogu i drugi ljudi.
05:32
I first started studying this constructive memory process
109
332726
5249
Prvi put sam počela da proučavam proces konstruktivnog pamćenja
05:37
in the 1970s.
110
337975
2415
sedamdesetih.
05:40
I did my experiments that involved showing people
111
340390
4423
Eksperimentisala sam puštajući ljudima
05:44
simulated crimes and accidents
112
344813
2505
simulirane zločine i nesreće
05:47
and asking them questions about what they remember.
113
347318
3518
i postavljajući im pitanja o tome čega se sećaju.
05:50
In one study, we showed people a simulated accident
114
350836
3939
U jednom eksperimentu pokazali smo simuliranu nesreću
05:54
and we asked people,
115
354775
1278
i pitali smo ljude
05:56
how fast were the cars going when they hit each other?
116
356053
2864
koliko brzo su automobili išli kada su se sudarili.
05:58
And we asked other people,
117
358917
1634
Druge smo pitali
06:00
how fast were the cars going when they smashed into each other?
118
360551
3689
koliko brzo su automobili išli kada su se razvalili.
06:04
And if we asked the leading "smashed" question,
119
364240
3002
Kada smo postavljali pitanje sa "razvalili",
06:07
the witnesses told us the cars were going faster,
120
367242
3285
svedoci su govorili da su automobili išli brže,
06:10
and moreover, that leading "smashed" question
121
370527
3997
štaviše, takvo pitanje
06:14
caused people to be more likely to tell us
122
374524
2860
je navelo ljude da nam kažu
06:17
that they saw broken glass in the accident scene
123
377384
3067
da su videli razbijeno staklo na mestu nesreće,
06:20
when there wasn't any broken glass at all.
124
380451
3779
gde razbijenog stakla nije bilo.
06:24
In another study, we showed a simulated accident
125
384230
2889
U drugoj studiji, prikazali smo simuliranu nesreću
06:27
where a car went through an intersection with a stop sign,
126
387119
3660
gde je auto prošao kroz raskrsnicu sa "stop" znakom,
06:30
and if we asked a question that insinuated it was a yield sign,
127
390779
4932
i kada smo postavili pitanje koje insinuira da je u pitanju trougao,
06:35
many witnesses told us they remember seeing a yield sign
128
395711
3849
mnogi svedoci su rekli da se sećaju da su videli trougao
06:39
at the intersection, not a stop sign.
129
399560
3457
na raskrsnici, a ne "stop".
06:43
And you might be thinking, well, you know,
130
403017
2189
Možda mislite
06:45
these are filmed events,
131
405206
1323
da su ovo snimljeni događaji,
06:46
they are not particularly stressful.
132
406529
1928
nisu naročito stresni.
06:48
Would the same kind of mistakes be made
133
408457
2734
Da li bi iste greške nastale
06:51
with a really stressful event?
134
411191
2951
sa zaista stresnim događajima?
06:54
In a study we published just a few months ago,
135
414142
3091
U jednoj studiji koju smo objavili pre samo nekoliko meseci,
06:57
we have an answer to this question,
136
417233
2304
imamo odgovor na to pitanje,
06:59
because what was unusual about this study
137
419537
2764
jer ono što je neobično u vezi sa ovom studijom,
07:02
is we arranged for people to have a very stressful experience.
138
422301
5632
je da smo namestili da ljudi dožive izuzetno stresno iskustvo.
07:07
The subjects in this study
139
427933
2229
Subjekti ove studije
07:10
were members of the U.S. military
140
430162
2510
bili su članovi američke vojske,
07:12
who were undergoing a harrowing training exercise
141
432672
4425
koji su prolazili kroz užasan trening
07:17
to teach them what it's going to be like for them
142
437097
2782
koji ih uči kako će im biti
07:19
if they are ever captured as prisoners of war.
143
439879
3918
ako ikada postanu ratni zarobljenici.
07:23
And as part of this training exercise,
144
443797
2430
Kao deo ove vežbe,
07:26
these soldiers are interrogated in an aggressive,
145
446227
3529
vojnici su ispitivani na agresivan,
07:29
hostile, physically abusive fashion for 30 minutes
146
449756
5086
neprijateljski, fizički nasilan način 30 minuta
07:34
and later on they have to try to identify
147
454842
2817
i kasnije treba da pokušaju da identifikuju
07:37
the person who conducted that interrogation.
148
457659
3023
osobu koja je sprovodila ispitivanje.
07:40
And when we feed them suggestive information
149
460682
3823
Kada im dajemo sugestivne informacije
07:44
that insinuates it's a different person,
150
464505
2778
koje navode na drugu osobu,
07:47
many of them misidentify their interrogator,
151
467283
4037
mnogi od njih pogrešno identifikuju svog ispitivača,
07:51
often identifying someone who doesn't even remotely
152
471320
3835
često identifikuju nekoga ko nimalo ne liči
07:55
resemble the real interrogator.
153
475155
3104
na pravog ispitivača.
07:58
And so what these studies are showing
154
478259
2301
Dakle, ove studije pokazuju
08:00
is that when you feed people misinformation
155
480560
3860
da, kada ljudima date pogrešne informacije
08:04
about some experience that they may have had,
156
484420
3380
o nekom iskustvu kroz koje su možda prošli,
08:07
you can distort or contaminate or change their memory.
157
487800
5655
možete iskriviti ili zatrovati ili promeniti njihovo pamćenje.
08:13
Well out there in the real world,
158
493455
2200
Pa, pogrešne informacije
08:15
misinformation is everywhere.
159
495655
2891
postoje svuda, u stvarnom svetu.
08:18
We get misinformation
160
498546
1360
Pogrešne informacije dobijamo
08:19
not only if we're questioned in a leading way,
161
499906
2916
ne samo kad smo navođeni u ispitivanju,
08:22
but if we talk to other witnesses
162
502822
2447
nego i ako razgovaramo sa drugim svedocima,
08:25
who might consciously or inadvertently feed us
163
505269
3033
koji mogu svesno ili nesvesno
08:28
some erroneous information,
164
508302
2137
da nam daju neke pogrešne informacije,
08:30
or if we see media coverage about some event we might have experienced,
165
510439
4730
ili kada vidimo medijski izveštaj o nekom događaju koji smo doživeli,
08:35
all of these provide the opportunity
166
515169
2793
sve ovo pruža priliku
08:37
for this kind of contamination of our memory.
167
517962
4350
za menjanje našeg sećanja.
08:42
In the 1990s, we began to see
168
522312
3788
Devedesetih smo počinjali da viđamo
08:46
an even more extreme kind of memory problem.
169
526100
4683
ekstremniju vrstu problema sa sećanjem.
08:50
Some patients were going into therapy with one problem --
170
530783
3096
Neki pacijenti su odlazili na terapiju sa jednim problemom -
08:53
maybe they had depression, an eating disorder --
171
533879
2914
možda depresijom ili poremećajem ishrane -
08:56
and they were coming out of therapy
172
536793
2753
a sa terapije izlazili
08:59
with a different problem.
173
539546
2661
sa drugim problemom.
09:02
Extreme memories for horrific brutalizations,
174
542207
3701
Ekstremna sećanja užasnih brutalizacija,
09:05
sometimes in satanic rituals,
175
545908
1983
ponekad satanističkih rituala,
09:07
sometimes involving really bizarre and unusual elements.
176
547891
4697
ponekad uključujući izuzetno bizarne i neobične elemente.
09:12
One woman came out of psychotherapy
177
552588
2554
Jedna žena je iz psihoterapije izašla
09:15
believing that she'd endured years
178
555142
2428
verujući da je pretrpela godine
09:17
of ritualistic abuse, where she was forced into a pregnancy
179
557570
3902
ritualističkih mučenja, gde je naterana na trudnoću
09:21
and that the baby was cut from her belly.
180
561472
2566
i gde joj je beba isečena iz stomaka.
09:24
But there were no physical scars
181
564038
2359
Ali nisu postojali fizički ožiljci
09:26
or any kind of physical evidence
182
566397
2026
ili bilo kakvi fizički dokazi
09:28
that could have supported her story.
183
568423
2881
koji bi potkrepili njenu priču.
09:31
And when I began looking into these cases,
184
571304
3008
Kada sam počela da istražujem ove slučajeve,
09:34
I was wondering,
185
574312
1450
pitala sam se,
09:35
where do these bizarre memories come from?
186
575762
2328
odakle dolaze ova bizarna sećanja?
09:38
And what I found is that most of these situations
187
578090
4387
Pronašla sam da većina ovih situacija
09:42
involved some particular form of psychotherapy.
188
582477
5491
uključuje neku određenu vrstu psihoterapije.
09:47
And so I asked,
189
587968
1599
I pitala sam
09:49
were some of the things going on in this psychotherapy --
190
589567
3388
da li neke od stvari koje se u toj psihoterapiji odvijaju -
09:52
like the imagination exercises
191
592955
2884
vežbe maštanja,
09:55
or dream interpretation,
192
595839
2057
interpretacije snova
09:57
or in some cases hypnosis,
193
597896
2132
ili u nekim slučajevima hipnoza,
10:00
or in some cases exposure to false information --
194
600028
3818
izlaganje lažnim informacijama -
10:03
were these leading these patients
195
603846
2787
da li to navodi pacijente
10:06
to develop these very bizarre,
196
606633
2677
da razviju ova bizarna,
10:09
unlikely memories?
197
609310
2931
neverovatna sećanja?
10:12
And I designed some experiments
198
612241
2159
Osmislila sam neke eksperimente
10:14
to try to study the processes that were being used
199
614400
5025
da pokušam da proučim procese koji su se koristili
10:19
in this psychotherapy so I could study
200
619425
3073
u ovoj psihoterapiji, da bih mogla da proučim
10:22
the development of these very rich false memories.
201
622498
3551
razvoj ovih bogatih lažnih sećanja.
10:26
In one of the first studies we did,
202
626049
2408
U jednom od prvih eksperimenata,
10:28
we used suggestion,
203
628457
2353
koristili smo sugestiju,
10:30
a method inspired by the psychotherapy we saw in these cases,
204
630810
4063
metod inspirisan psihoterapijom koju smo videli u ovim slučajevima,
10:34
we used this kind of suggestion
205
634873
2110
koristili smo tu vrstu sugestije,
10:36
and planted a false memory
206
636983
1852
i usadili lažno sećanje,
10:38
that when you were a kid, five or six years old,
207
638835
3077
da ste se, kad ste bili dete, sa pet ili šest godina,
10:41
you were lost in a shopping mall.
208
641912
2251
izgubili u tržnom centru.
10:44
You were frightened. You were crying.
209
644163
2500
Bili ste uplašeni. Plakali ste.
10:46
You were ultimately rescued by an elderly person
210
646663
2514
Na kraju vas je spasila starija osoba
10:49
and reunited with the family.
211
649177
1852
i vratila vašoj porodici.
10:51
And we succeeded in planting this memory
212
651029
2608
Uspeli smo da usadimo ovo sećanje
10:53
in the minds of about a quarter of our subjects.
213
653637
4106
u umove otprilike četvrtine naših subjekata.
10:57
And you might be thinking, well,
214
657743
2005
Možda mislite, pa dobro,
10:59
that's not particularly stressful.
215
659748
2346
to nije baš stresno.
11:02
But we and other investigators have planted
216
662094
3369
Ali mi i drugi istraživači smo usadili
11:05
rich false memories of things that were
217
665463
2758
bogata lažna sećanja na stvari koje su bile
11:08
much more unusual and much more stressful.
218
668221
2915
mnogo neuobičajenije i mnogo stresnije.
11:11
So in a study done in Tennessee,
219
671136
2539
U jednoj studiji u Tenesiju,
11:13
researchers planted the false memory
220
673675
2416
istraživači su usadili lažno sećanje
11:16
that when you were a kid, you nearly drowned
221
676091
2574
da ste se, kao mali, skoro udavili
11:18
and had to be rescued by a life guard.
222
678665
2507
i morao je da vam pomogne spasilac.
11:21
And in a study done in Canada,
223
681172
2303
U jednoj studiji u Kanadi,
11:23
researchers planted the false memory
224
683475
2524
istraživači su usadili lažno sećanje
11:25
that when you were a kid,
225
685999
1228
da vam se, kao detetu,
11:27
something as awful as being attacked by a vicious animal
226
687227
3730
desilo nešto strašno kao što je
11:30
happened to you,
227
690957
1382
napad divlje životinje,
11:32
succeeding with about half of their subjects.
228
692339
3422
i to je uspelo kod oko polovine njihovih subjekata.
11:35
And in a study done in Italy,
229
695761
2352
A u studiji u Italiji,
11:38
researchers planted the false memory,
230
698113
2658
istraživači su usadili lažno sećanje
11:40
when you were a kid, you witnessed demonic possession.
231
700771
5212
da ste, kao dete, bili svedok demonske posednutosti.
11:45
I do want to add that it might seem
232
705983
2207
Želim da dodam da možda izgleda
11:48
like we are traumatizing these experimental subjects
233
708190
3739
kao da traumatizujemo ove subjekte
11:51
in the name of science,
234
711929
1600
u ime nauke,
11:53
but our studies have gone through thorough evaluation
235
713529
4638
ali naše studije su prošle kroz detaljnu evaluaciju
11:58
by research ethics boards
236
718167
1975
istraživačkih etičkih komisija,
12:00
that have made the decision
237
720142
2342
koje su odlučile
12:02
that the temporary discomfort that some
238
722484
3073
da je trenutna nelagoda
12:05
of these subjects might experience in these studies
239
725557
3084
koju neki od subjekata možda osete u ovim studijama
12:08
is outweighed by the importance of this problem
240
728641
3900
nadjačana značajem ovog problema
12:12
for understanding memory processes
241
732541
3107
za razumevanje procesa pamćenja
12:15
and the abuse of memory that is going on
242
735648
3346
i zloupotrebe pamćenja koje se dešava
12:18
in some places in the world.
243
738994
3293
na nekim mestima u svetu.
12:22
Well, to my surprise,
244
742287
3038
Pa, na moje iznenađenje,
12:25
when I published this work and began to speak out
245
745325
3429
kada sam objavila ovaj rad i počela da govorim
12:28
against this particular brand of psychotherapy,
246
748754
3895
protiv ove vrste psihoterapije,
12:32
it created some pretty bad problems for me:
247
752649
3980
to mi je stvorilo neke gadne probleme:
12:36
hostilities, primarily from the repressed memory therapists,
248
756629
4901
neprijateljstva, prvenstveno od terapeuta potisnutih sećanja,
12:41
who felt under attack,
249
761530
1676
koji su se osetili napadnutim,
12:43
and by the patients whom they had influenced.
250
763206
3528
i od pacijenata na koje su uticali.
12:46
I had sometimes armed guards at speeches
251
766734
2937
Ponekada sam imala naoružano obezbeđenje
12:49
that I was invited to give,
252
769671
1905
na govorima koje sam držala,
12:51
people trying to drum up letter-writing campaigns to get me fired.
253
771576
4217
ljudi su pokušavali da sprovedu kampanje kojima bi me otpustili.
12:55
But probably the worst
254
775793
1981
Ali možda najgore,
12:57
was I suspected that a woman
255
777774
2767
sumnjala sam da je jedna žena
13:00
was innocent of abuse
256
780541
2424
nevina za zlostavljanje
13:02
that was being claimed by her grown daughter.
257
782965
2836
za koje ju je optužila njena odrasla ćerka.
13:05
She accused her mother of sexual abuse
258
785801
3417
Optužila je majku za seksualno zlostavljanje
13:09
based on a repressed memory.
259
789218
1859
zasnovano na potisnutom sećanju.
13:11
And this accusing daughter had actually allowed her story
260
791077
2883
Ova ćerka je dozvolila da se njena priča
13:13
to be filmed and presented in public places.
261
793960
3434
snimi i prikazuje na javnim mestima.
13:17
I was suspicious of this story,
262
797394
2509
Posumnjala sam u tu priču
13:19
and so I started to investigate,
263
799903
2300
i počela da istražujem,
13:22
and eventually found information that convinced me
264
802203
4483
naposletku našavši informacije koje su me ubedile
13:26
that this mother was innocent.
265
806686
2289
da je ta majka nevina.
13:28
I published an exposé on the case,
266
808975
2961
Objavila sam izveštaj o slučaju,
13:31
and a little while later, the accusing daughter
267
811936
3444
i malo kasnije, ta ćerka
13:35
filed a lawsuit.
268
815380
1521
je podigla tužbu.
13:36
Even though I'd never mentioned her name,
269
816901
2355
Iako nikad nisam pomenula njeno ime,
13:39
she sued me for defamation and invasion of privacy.
270
819256
4362
tužila me je za povredu časti i privatnosti.
13:43
And I went through nearly five years
271
823618
2723
Prošla sam kroz skoro 5 godina
13:46
of dealing with this messy, unpleasant litigation,
272
826341
6552
borbe sa tom haotičnom, neprijatnom parnicom,
13:52
but finally, finally, it was over and I could really
273
832893
3674
ali konačno je sve bilo gotovo
13:56
get back to my work.
274
836567
2424
i mogla sam da se vratim svom poslu.
13:58
In the process, however, I became part
275
838991
2485
Međutim, u tom procesu sam postala deo
14:01
of a disturbing trend in America
276
841476
2654
uznemiravajućeg trenda u Americi,
14:04
where scientists are being sued
277
844130
2107
gde se naučnici tuže
14:06
for simply speaking out on matters of great public controversy.
278
846237
4599
zbog iznošenja mišljenja o stvarima velike javne kontraverze.
14:10
When I got back to my work, I asked this question:
279
850836
3358
Kada sam se vratila poslu, postavila sam sledeće pitanje:
14:14
if I plant a false memory in your mind,
280
854194
2398
ako u vaš um ubacim lažno sećanje,
14:16
does it have repercussions?
281
856592
1844
da li to ima posledica?
14:18
Does it affect your later thoughts,
282
858436
1959
Da li utiče na vaše kasnije misli,
14:20
your later behaviors?
283
860395
2101
vaša kasnija ponašanja?
14:22
Our first study planted a false memory
284
862496
2027
Naš prvi eksperiment ubacio je lažno sećanje
14:24
that you got sick as a child eating certain foods:
285
864523
3326
da ste se kao dete razboleli jedući određenu hranu;
14:27
hard-boiled eggs, dill pickles, strawberry ice cream.
286
867849
2999
tvrdo kuvana jaja, turšiju, sladoled od jagoda.
14:30
And we found that once we planted this false memory,
287
870848
3190
Otkrili smo da, kada ubacimo ova sećanja,
14:34
people didn't want to eat the foods as much
288
874038
2451
ljudi na pikniku nisu više želeli
14:36
at an outdoor picnic.
289
876489
2260
da jedu tu hranu.
14:38
The false memories aren't necessarily bad or unpleasant.
290
878749
3873
Lažna sećanja nisu obavezno loša ili neprijatna.
14:42
If we planted a warm, fuzzy memory
291
882622
2358
Ako ubacimo toplo, prijatno sećanje
14:44
involving a healthy food like asparagus,
292
884980
3021
koje uključuje zdravu hranu kao što je špargla,
14:48
we could get people to want to eat asparagus more.
293
888001
3475
možemo navesti ljude da žele da jedu više špargle.
14:51
And so what these studies are showing
294
891476
2374
Ove studije pokazuju
14:53
is that you can plant false memories
295
893850
2115
da možete ubaciti lažna sećanja
14:55
and they have repercussions
296
895965
1413
i ona imaju posledice
14:57
that affect behavior long after the memories take hold.
297
897378
5085
na ponašanje mnogo vremena kasnije.
15:02
Well, along with this ability
298
902463
2424
Pa, sa ovom sposobnošću
15:04
to plant memories and control behavior
299
904887
2923
za postavljanjem sećanja i kontrolisanjem ponašanja,
15:07
obviously come some important ethical issues,
300
907810
4181
očigledno dolaze i neka važna etička pitanja,
15:11
like, when should we use this mind technology?
301
911991
3059
na primer, kada bi trebalo da koristimo ovu tehnologiju uma?
15:15
And should we ever ban its use?

Da li bi trebalo da zabranimo njenu upotrebu?
15:18
Therapists can't ethically plant false memories
303
918730
2783
Terapeuti ne mogu etički da ubacuju lažna sećanja
15:21
in the mind of their patients
304
921513
1587
u umove pacijenata,
15:23
even if it would help the patient,
305
923100
2564
čak i kada bi to pacijentu pomoglo,
15:25
but there's nothing to stop a parent
306
925664
1622
ali ništa ne sprečava roditelja
15:27
from trying this out on their overweight or obese teenager.
307
927286
4449
da ovo isproba na svom gojaznom tinejdžeru.
15:31
And when I suggested this publicly,
308
931735
2605
Kada sam ovo javno rekla,
15:34
it created an outcry again.
309
934340
3346
to je ponovo stvorilo pobunu.
15:37
"There she goes. She's advocating that parents lie to their children."
310
937686
4033
"Evo je opet. Zagovara da roditelji lažu svoju decu".
15:41
Hello, Santa Claus. (Laughter)
311
941719
2245
Zdravo, Deda Mraze. (Smeh)
15:43
I mean, another way to think about this is,
312
943964
9497
Mislim, možete se i zapitati
15:53
which would you rather have,
313
953461
2033
šta biste radije imali,
15:55
a kid with obesity, diabetes, shortened lifespan,
314
955494
3029
dete sa gojaznošću, dijabetesom, kraćim životnim vekom
15:58
all the things that go with it,
315
958523
1532
i svime što sa tim ide
16:00
or a kid with one little extra bit of false memory?
316
960055
3016
ili dete sa jednim lažnim sećanjem više?
16:03
I know what I would choose for a kid of mine.
317
963071
3391
Znam šta bih ja izabrala za svoje dete.
16:06
But maybe my work has made me different from most people.
318
966462
3977
Ali možda je mene moj posao učinio drugačijom od većine.
16:10
Most people cherish their memories,
319
970439
2079
Većina voli svoja sećanja,
16:12
know that they represent their identity,
320
972518
2154
zna da ona predstavljaju njihov identitet,
16:14
who they are, where they came from.
321
974672
2025
ono ko su i odakle dolaze.
16:16
And I appreciate that. I feel that way too.
322
976697
2858
Ja poštujem to. I ja se tako osećam.
16:19
But I know from my work
323
979555
2205
Ali iz svog posla znam
16:21
how much fiction is already in there.
324
981760
4481
koliko je fikcije već prisutno tu.
16:26
If I've learned anything from these decades
325
986241
2732
Ako sam išta naučila iz ovih decenija
16:28
of working on these problems, it's this:
326
988973
2410
rada na ovim problema, to je ovo:
16:31
just because somebody tells you something
327
991383
2211
samo zato što vam neko nešto kaže
16:33
and they say it with confidence,
328
993594
1575
i to čini sa poverenjem,
16:35
just because they say it with lots of detail,
329
995169
2680
samo zato što to kaže sa mnogo detalja
16:37
just because they express emotion when they say it,
330
997849
2759
i sa mnogo emocija,
16:40
it doesn't mean that it really happened.
331
1000608
3202
ne znači da se to zaista dogodilo.
16:43
We can't reliably distinguish true memories from false memories.
332
1003810
3865
Ne možemo pouzdano razlikovati istinita od lažnih sećanja.
16:47
We need independent corroboration.
333
1007675
3548
Potrebni su nam nezavisni dokazi.
16:51
Such a discovery has made me more tolerant
334
1011223
3090
To otkriće me je učinilo tolerantnijom
16:54
of the everyday memory mistakes
335
1014313
2139
na svakodnevne greške u pamćenju
16:56
that my friends and family members make.
336
1016452
2914
koje čine moji prijatelji i porodica.
16:59
Such a discovery might have saved Steve Titus,
337
1019366
4534
Takvo otkriće je moglo da spase Stiva Tajtusa,
17:03
the man whose whole future was snatched away
338
1023900
3576
čoveka čiju celu budućnost je oduzelo
17:07
by a false memory.
339
1027476
2238
jedno lažno sećanje.
17:09
But meanwhile, we should all keep in mind,
340
1029714
2816
Ali u međuvremenu, trebalo bi da zapamtimo,
17:12
we'd do well to,
341
1032530
1636
bolje da zapamtimo,
17:14
that memory, like liberty,
342
1034166
3871
da je pamćenje, kao sloboda,
17:18
is a fragile thing.
343
1038037
3694
osetljiva stvar.
17:21
Thank you. Thank you.
344
1041731
2938
Hvala vam.
17:24
Thank you. (Applause)
345
1044669
2728
Hvala vam. (Aplauz)
17:27
Thanks very much. (Applause)
346
1047397

Hvala vam mnogo. (Aplauz)
