I want to talk to you today a little bit
0
19330
2000
Danas bih vam htio malo govoriti
00:21
about predictable irrationality.
1
21330
3000
o predvidljivoj iracionalnosti.
00:24
And my interest in irrational behavior
2
24330
4000
Moj interes za iracionalno ponašanje
00:28
started many years ago in the hospital.
3
28330
3000
počeo je prije mnogo godina u bolnici.
00:31
I was burned very badly.
4
31330
4000
Imao sam teške opekline.
00:35
And if you spend a lot of time in hospital,
5
35330
3000
I ako provedete mnogo vremena u bolnici,
00:38
you'll see a lot of types of irrationalities.
6
38330
3000
vidjet ćete mnogo vrsta iracionalnosti.
00:41
And the one that particularly bothered me in the burn department
7
41330
5000
Jedan koji me osobito smetao u Odjelu za opekline
00:46
was the process by which the nurses took the bandage off me.
8
46330
4000
bio je proces kojim su sestre skidale zavoje s mene.
00:51
Now, you must have all taken a Band-Aid off at some point,
9
51330
2000
Svi ste jednom skidali flaster
00:53
and you must have wondered what's the right approach.
10
53330
3000
i pitali ste se koji je pravi pristup.
00:56
Do you rip it off quickly -- short duration but high intensity --
11
56330
4000
Želite li ga otrgnuti brzo – kratko trajanje uz intenzivnu bol –
01:00
or do you take your Band-Aid off slowly --
12
60330
2000
ili ga želite skinuti sporo –
01:02
you take a long time, but each second is not as painful --
13
62330
4000
dugo trajanje, ali svaka sekunda nije toliko bolna –
01:06
which one of those is the right approach?
14
66330
3000
– koji od ta dva pristupa je pravi?
01:09
The nurses in my department thought that the right approach
15
69330
4000
Sestre na mom odjelu mislile su da je pravi pristup
01:13
was the ripping one, so they would grab hold and they would rip,
16
73330
3000
brzog skidanja zavoja, tako bi ga one zgrabile i naglo otkinule,
01:16
and they would grab hold and they would rip.
17
76330
2000
i zgrabile bi i otkinule.
01:18
And because I had 70 percent of my body burned, it would take about an hour.
18
78330
4000
S obzirom da sam ima 70% tijela opečeno, to bi trajalo negdje oko sat vremena.
01:22
And as you can imagine,
19
82330
3000
Možete zamisliti,
01:25
I hated that moment of ripping with incredible intensity.
20
85330
4000
mrzio sam taj trenutak skidanja zavoja uz nevjerojatni intenzitet.
01:29
And I would try to reason with them and say,
21
89330
2000
Pokušao sam ih urazumiti i rekao,
01:31
"Why don't we try something else?
22
91330
1000
"Zašto ne pokušamo nešto drugo?
01:32
Why don't we take it a little longer --
23
92330
2000
Zašto ne bi trajalo malo duže –
01:34
maybe two hours instead of an hour -- and have less of this intensity?"
24
94330
5000
možda dva sata umjesto jednog – i bilo manjeg intenziteta boli?"
01:39
And the nurses told me two things.
25
99330
2000
Sestre su mi rekle dvije stvari.
01:41
They told me that they had the right model of the patient --
26
101330
4000
Rekle su mi da imaju pravi model za pacijenta –
01:45
that they knew what was the right thing to do to minimize my pain --
27
105330
3000
da znaju što treba učiniti kako bi umanjile bol –
01:48
and they also told me that the word patient doesn't mean
28
108330
3000
također su mi rekle da termin pacijent (strpljiv) ne znači
01:51
to make suggestions or to interfere or ...
29
111330
2000
da mogu davati prijedloge ili ometati ili...
01:53
This is not just in Hebrew, by the way.
30
113330
3000
I to ne samo na hebrejskom.
01:56
It's in every language I've had experience with so far.
31
116330
3000
Već na svakom jeziku kojeg sam iskusio do sada.
01:59
And, you know, there's not much -- there wasn't much I could do,
32
119330
4000
Znate, nema puno – nije bilo puno toga što sam mogao napraviti
02:03
and they kept on doing what they were doing.
33
123330
3000
i one bi nastavljale raditi po starom modelu.
02:06
And about three years later, when I left the hospital,
34
126330
2000
Poslije tri godine, kada sam izašao iz bolnice,
02:08
I started studying at the university.
35
128330
3000
počeo sam studirati na sveučilištu.
02:11
And one of the most interesting lessons I learned
36
131330
3000
Jedna od najzanimljivijih lekcija koje sam naučio
02:14
was that there is an experimental method
37
134330
2000
je ta da postoji eksperimentalna metoda
02:16
that if you have a question you can create a replica of this question
38
136330
4000
kojom ako imate pitanje, možete napraviti repliku tog pitanja
02:20
in some abstract way, and you can try to examine this question,
39
140330
4000
na neki apstraktni način i možete ispitati to pitanje,
02:24
maybe learn something about the world.
40
144330
2000
možda naučite nešto o svijetu.
02:26
So that's what I did.
41
146330
2000
To sam i napravio.
02:28
I was still interested
42
148330
1000
Još uvijek sam bio zainteresiran
02:29
in this question of how do you take bandages off burn patients.
43
149330
2000
pitanjem kako skinuti zavoje sa opečenih pacijenata.
02:31
So originally I didn't have much money,
44
151330
3000
Prvotno, nisam imao mnogo novca,
02:34
so I went to a hardware store and I bought a carpenter's vice.
45
154330
4000
tako sam otišao u željezariju i kupio škripac.
02:38
And I would bring people to the lab and I would put their finger in it,
46
158330
4000
Dovodio bih ljude u laboratorij i stavljao njihove prste u to,
02:42
and I would crunch it a little bit.
47
162330
2000
i onda bi ih malo drobio.
02:44
(Laughter)
48
164330
2000
(Smijeh)
02:46
And I would crunch it for long periods and short periods,
49
166330
3000
Drobio bih ih kroz duge i kratke periode,
02:49
and pain that went up and pain that went down,
50
169330
2000
i uz pojačavanje boli i uz smanjivanje boli,
02:51
and with breaks and without breaks -- all kinds of versions of pain.
51
171330
4000
uz pauze i bez pauza – svakakve verzije boli.
02:55
And when I finished hurting people a little bit, I would ask them,
52
175330
2000
Kada sam završio ranjavati ljude, pitao bih ih,
02:57
so, how painful was this? Or, how painful was this?
53
177330
2000
koliko bolno je bilo? Ili, koliko bolno je bilo ovo?
02:59
Or, if you had to choose between the last two,
54
179330
2000
Ili, ako biste mogli birati između zadnja dva,
03:01
which one would you choose?
55
181330
2000
koje biste izabrali?
03:03
(Laughter)
56
183330
3000
(Smijeh)
03:06
I kept on doing this for a while.
57
186330
3000
Radio sam to neko vrijeme.
03:09
(Laughter)
58
189330
2000
(Smijeh)
03:11
And then, like all good academic projects, I got more funding.
59
191330
4000
Tada, kao i svi dobri akademski projekt, dobio sam više sredstava.
03:15
I moved to sounds, electrical shocks --
60
195330
2000
Prešao sam na zvukove, elektrošokove –
03:17
I even had a pain suit that I could get people to feel much more pain.
61
197330
5000
imao sam čak i odijelo boli u kojem su ljudi osjećali mnogo više boli.
03:22
But at the end of this process,
62
202330
4000
Ali na kraju procesa,
03:26
what I learned was that the nurses were wrong.
63
206330
3000
naučio sam da su sestre bile u krivu.
03:29
Here were wonderful people with good intentions
64
209330
3000
Bili su to prekrasni ljudi sa dobrim namjerama
03:32
and plenty of experience, and nevertheless
65
212330
2000
i sa puno iskustva, ali ipak
03:34
they were getting things wrong predictably all the time.
66
214330
4000
predvidljivo su griješili cijelo vrijeme.
03:38
It turns out that because we don't encode duration
67
218330
3000
Tako je ispalo jer ne kodiramo trajanje
03:41
in the way that we encode intensity,
68
221330
2000
na način na koji kodiramo intenzitet,
03:43
I would have had less pain if the duration would have been longer
69
223330
4000
bilo bi mi manje bolno da je trajanje bilo duže,
03:47
and the intensity was lower.
70
227330
2000
a intenzitet manji.
03:49
It turns out it would have been better to start with my face,
71
229330
3000
Ispalo je da bi bilo bolje početi s mojim licem,
03:52
which was much more painful, and move toward my legs,
72
232330
2000
koje je bilo najbolnije, i kretati se prema mojim nogama,
03:54
giving me a trend of improvement over time --
73
234330
3000
dajući mi osjećaj napretka tijekom vremena –
03:57
that would have been also less painful.
74
237330
1000
što bi također bilo manje bolno.
03:58
And it also turns out that it would have been good
75
238330
2000
Ispada da bi bilo dobro
04:00
to give me breaks in the middle to kind of recuperate from the pain.
76
240330
2000
davati mi pauze u sredini procesa kako bih se malo oporavio od boli.
04:02
All of these would have been great things to do,
77
242330
2000
To bi sve bilo jako dobro za napraviti,
04:04
and my nurses had no idea.
78
244330
3000
a moje sestre nisu imale ideju o tome.
04:07
And from that point on I started thinking,
79
247330
1000
Tada sam počeo razmišljati,
04:08
are the nurses the only people in the world who get things wrong
80
248330
3000
jesu li medicinske sestre jedini ljudi na svijetu koji pogrešno odlučuju,
04:11
in this particular decision, or is it a more general case?
81
251330
3000
ili je to općenitiji slučaj?
04:14
And it turns out it's a more general case --
82
254330
2000
Ispada da je to općenitiji slučaj –
04:16
there's a lot of mistakes we do.
83
256330
3000
radimo puno grešaka.
04:19
And I want to give you one example of one of these irrationalities,
84
259330
5000
Htio bih vam dati primjer jedne od tih iracionalnosti,
04:24
and I want to talk to you about cheating.
85
264330
3000
htio bih vam govoriti i o varanju.
04:27
And the reason I picked cheating is because it's interesting,
86
267330
2000
Razlog zbog kojeg sam izabrao varanje je zato što je zanimljivo,
04:29
but also it tells us something, I think,
87
269330
2000
ali nam u isto vrijeme i govori nešto, mislim,
04:31
about the stock market situation we're in.
88
271330
3000
o situaciji stanja dionica na tržištu u kojoj se nalazimo.
04:34
So, my interest in cheating started
89
274330
3000
tako je moj interes za varanje je počeo
04:37
when Enron came on the scene, exploded all of a sudden,
90
277330
2000
kada je Enron došao na scenu i iznenada eksplodirao,
04:39
and I started thinking about what is happening here.
91
279330
3000
počeo sam razmišljati što se tamo događa.
04:42
Is it the case that there was kind of
92
282330
1000
Postoji li tamo samo nekoliko
04:43
a few apples who are capable of doing these things,
93
283330
3000
pokvarenih jabuka koje su u stanju učiniti te stvari
04:46
or are we talking a more endemic situation,
94
286330
2000
ili govorimo o endemskoj situaciji
04:48
that many people are actually capable of behaving this way?
95
288330
4000
gdje su mnogi ljudi u stanju ponašati se na taj način?
04:52
So, like we usually do, I decided to do a simple experiment.
96
292330
4000
Kao što inače radimo, odlučio sam napraviti jednostavan eksperiment.
04:56
And here's how it went.
97
296330
1000
Evo što sam napravio.
04:57
If you were in the experiment, I would pass you a sheet of paper
98
297330
3000
Da ste u eksperimentu, dao bih vam list papira
05:00
with 20 simple math problems that everybody could solve,
99
300330
4000
sa 20 jednostavnih matematičkih problema koje svatko može riješiti,
05:04
but I wouldn't give you enough time.
100
304330
2000
ali ne bih vam dao dovoljno vremena.
05:06
When the five minutes were over, I would say,
101
306330
2000
Kada bi 5 minuta završilo, rekao bih,
05:08
"Pass me the sheets of paper, and I'll pay you a dollar per question."
102
308330
3000
"Dodajte mi list papira i platit ću vam dolar po odgovorenom pitanju."
05:11
People did this. I would pay people four dollars for their task --
103
311330
4000
Ljudi bi to napravili a ja bih platio 4 dolara za njihov zadatak –
05:15
on average people would solve four problems.
104
315330
2000
prosječno bi ljudi riješili 4 problema.
05:17
Other people I would tempt to cheat.
105
317330
3000
Druge ljude bih namamio da varaju.
05:20
I would pass their sheet of paper.
106
320330
1000
Dodao bih im list papira.
05:21
When the five minutes were over, I would say,
107
321330
2000
Kada bi 5 minuta završilo, rekao bih,
05:23
"Please shred the piece of paper.
108
323330
1000
"Molim vas potrgajte papir na komadiće.
05:24
Put the little pieces in your pocket or in your backpack,
109
324330
3000
Stavite komadiće u džepove ili u ruksak,
05:27
and tell me how many questions you got correctly."
110
327330
3000
i recite mi koliko ste pitanja riješili točno."
05:30
People now solved seven questions on average.
111
330330
3000
Ljudi su sada „riješili” 7 pitanja prosječno.
05:33
Now, it wasn't as if there was a few bad apples --
112
333330
5000
Nije tu bilo nekoliko pokvarenih jabuka –
05:38
a few people cheated a lot.
113
338330
3000
nekoliko ljudi koji su varali puno.
05:41
Instead, what we saw is a lot of people who cheat a little bit.
114
341330
3000
Umjesto toga, uvidjeli smo da je puno ljudi varalo malo.
05:44
Now, in economic theory,
115
344330
3000
U ekonomskoj teoriji,
05:47
cheating is a very simple cost-benefit analysis.
116
347330
3000
varanje je vrlo jednostavna analiza troškova i koristi.
05:50
You say, what's the probability of being caught?
117
350330
2000
Razmislite, koja je vjerojatnost da budete uhvaćeni?
05:52
How much do I stand to gain from cheating?
118
352330
3000
Koliko ću dobiti zbog varanja?
05:55
And how much punishment would I get if I get caught?
119
355330
2000
Koliku kaznu ću dobiti ako me uhvate?
05:57
And you weigh these options out --
120
357330
2000
Izvažete te opcije –
05:59
you do the simple cost-benefit analysis,
121
359330
2000
napravite jednostavnu analizu troškova i koristi,
06:01
and you decide whether it's worthwhile to commit the crime or not.
122
361330
3000
odlučite isplati li se počiniti zločin ili ne.
06:04
So, we try to test this.
123
364330
2000
Tako smo se odlučili ispitati i to.
06:06
For some people, we varied how much money they could get away with --
124
366330
4000
Nekim ljudima mijenjali smo iznos novca koji bi dobili –
06:10
how much money they could steal.
125
370330
1000
odnosno koliko novca mogu ukrasti.
06:11
We paid them 10 cents per correct question, 50 cents,
126
371330
3000
Platili bismo im 10 centi za točno pitanje, 50 centi,
06:14
a dollar, five dollars, 10 dollars per correct question.
127
374330
3000
dolar, pet dolara, 10 dolara za točno pitanje.
06:17
You would expect that as the amount of money on the table increases,
128
377330
4000
Očekivali biste da dok se količina ponuđenog novca povećava,
06:21
people would cheat more, but in fact it wasn't the case.
129
381330
3000
ljudi će varati više, ali to nije bio slučaj.
06:24
We got a lot of people cheating by stealing by a little bit.
130
384330
3000
Dobili smo puno ljudi koji su varali tako što bi ukrali jako malo.
06:27
What about the probability of being caught?
131
387330
3000
Što je s vjerojatnošću da budu uhvaćeni?
06:30
Some people shredded half the sheet of paper,
132
390330
2000
Neki ljudi su poderali pola lista papira,
06:32
so there was some evidence left.
133
392330
1000
tako da je ostao neki dokaz.
06:33
Some people shredded the whole sheet of paper.
134
393330
2000
Neki ljudi su poderali cijeli papir.
06:35
Some people shredded everything, went out of the room,
135
395330
3000
Neki ljudi su poderali sve, otišli iz sobe
06:38
and paid themselves from the bowl of money that had over 100 dollars.
136
398330
3000
i isplatili sebe iz zdjele u kojoj je bilo više od 100 dolara.
06:41
You would expect that as the probability of being caught goes down,
137
401330
3000
Očekivali biste da dok se vjerojatnost da budete uhvaćeni smanjuje
06:44
people would cheat more, but again, this was not the case.
138
404330
3000
ljudi će varati više, ali opet, to nije bio slučaj.
06:47
Again, a lot of people cheated by just by a little bit,
139
407330
3000
Opet, mnogo ljudi je varalo malo
06:50
and they were insensitive to these economic incentives.
140
410330
3000
i oni su bili neosjetljivi na te ekonomske poticaje.
06:53
So we said, "If people are not sensitive
141
413330
1000
Rekli smo, “Ako ljudi nisu osjetljivi
06:54
to the economic rational theory explanations, to these forces,
142
414330
5000
na racionalna ekonomska teorijska objašnjenja, na te sile,
06:59
what could be going on?"
143
419330
3000
što se događalo?”
07:02
And we thought maybe what is happening is that there are two forces.
144
422330
3000
Možda se događalo to da su postojale dvije sile.
07:05
At one hand, we all want to look at ourselves in the mirror
145
425330
2000
U jednu ruku, svi želimo sebe pogledati u ogledalu
07:07
and feel good about ourselves, so we don't want to cheat.
146
427330
3000
i osjećati se dobro sami sa sobom, pa ne želimo varati.
07:10
On the other hand, we can cheat a little bit,
147
430330
2000
U drugu ruku, možemo varati malo
07:12
and still feel good about ourselves.
148
432330
2000
i time ne narušiti osjećaj zadovoljstva samih sobom.
07:14
So, maybe what is happening is that
149
434330
1000
Možda se događalo to da
07:15
there's a level of cheating we can't go over,
150
435330
2000
postoji razina varanja koju ne možemo prijeći,
07:17
but we can still benefit from cheating at a low degree,
151
437330
4000
dakle varanje nam može koristiti na nekom nižem stupnju,
07:21
as long as it doesn't change our impressions about ourselves.
152
441330
3000
dokle god to ne mijenjamo naše utiske o nama samima.
07:24
We call this like a personal fudge factor.
153
444330
3000
Zovemo to nešto kao osobni čimbenik gluposti.
07:28
Now, how would you test a personal fudge factor?
154
448330
4000
Sada, kako biste testirali osobno čimbenik gluposti?
07:32
Initially we said, what can we do to shrink the fudge factor?
155
452330
4000
Inicijalno smo rekli, što možemo učiniti da smanjimo čimbenik gluposti?
07:36
So, we got people to the lab, and we said,
156
456330
2000
Doveli smo ljude u laboratorij i rekli,
07:38
"We have two tasks for you today."
157
458330
2000
“Danas imamo dva zadatka za vas.”
07:40
First, we asked half the people
158
460330
1000
Prvo, smo pitali pola ljudi
07:41
to recall either 10 books they read in high school,
159
461330
2000
da se sjete 10 knjiga koje su pročitali u srednjoj školi
07:43
or to recall The Ten Commandments,
160
463330
3000
ili da se sjete 10 Božjih zapovjedi,
07:46
and then we tempted them with cheating.
161
466330
2000
i tada smo ih namamili na varanje.
07:48
Turns out the people who tried to recall The Ten Commandments --
162
468330
3000
Ispada kako ljudi koji su se pokušali sjetiti 10 zapovjedi –
07:51
and in our sample nobody could recall all of The Ten Commandments --
163
471330
2000
u našem uzorku se nitko nije mogao sjetiti svih 10 zapovjedi –
07:54
but those people who tried to recall The Ten Commandments,
164
474330
4000
ali tim ljudima koji su se pokušali sjetiti 10 zapovjedi
07:58
given the opportunity to cheat, did not cheat at all.
165
478330
3000
dana je prilika da varaju i oni nisu uopće varali.
08:01
It wasn't that the more religious people --
166
481330
2000
Nije da su religiozniji ljudi –
08:03
the people who remembered more of the Commandments -- cheated less,
167
483330
1000
oni ljudi koji su se sjetili više zapovjedi – varali manje,
08:04
and the less religious people --
168
484330
2000
a da su manje religiozni ljudi –
08:06
the people who couldn't remember almost any Commandments --
169
486330
1000
ljudi koji se nisu mogli sjetiti skoro nijedne zapovjedi –
08:07
cheated more.
170
487330
2000
varali više.
08:09
The moment people thought about trying to recall The Ten Commandments,
171
489330
4000
U trenutku kada su se ljudi pokušali sjetiti 10 zapovjedi,
08:13
they stopped cheating.
172
493330
1000
prestali bi varati.
08:14
In fact, even when we gave self-declared atheists
173
494330
2000
U stvari, čak i kada smo dali samo-prozvanim ateistima
08:16
the task of swearing on the Bible and we give them a chance to cheat,
174
496330
4000
zadatak da se zakunu na Bibliju i dali im priliku da varaju,
08:20
they don't cheat at all.
175
500330
2000
nisu varali uopće.
08:24
Now, Ten Commandments is something that is hard
176
504330
2000
10 zapovjedi je nešto što je jako teško
08:26
to bring into the education system, so we said,
177
506330
2000
unijeti u obrazovni sustav, pa smo rekli,
08:28
"Why don't we get people to sign the honor code?"
178
508330
2000
“Zašto ne bismo rekli ljudima da potpišu kodeks časti?”
08:30
So, we got people to sign,
179
510330
2000
Doveli smo ljude na potpišu,
08:32
"I understand that this short survey falls under the MIT Honor Code."
180
512330
4000
“Razumijem da ova kratka anketa spada u MIT kodeks časti.”
08:36
Then they shredded it. No cheating whatsoever.
181
516330
3000
Tada bi poderali tu izjavu. I dalje nije bilo varanja.
08:39
And this is particularly interesting,
182
519330
1000
To je posebno zanimljivo,
08:40
because MIT doesn't have an honor code.
183
520330
2000
zato što MIT nema kodeks časti.
08:42
(Laughter)
184
522330
5000
(Smijeh)
08:47
So, all this was about decreasing the fudge factor.
185
527330
4000
Sve smo to napravili samo da bismo smanjili čimbenik gluposti.
08:51
What about increasing the fudge factor?
186
531330
3000
Što je s povećanjem čimbenika gluposti?
08:54
The first experiment -- I walked around MIT
187
534330
2000
Prvi eksperiment – hodao sam po MIT-u
08:56
and I distributed six-packs of Cokes in the refrigerators --
188
536330
3000
i raspodijelio pakiranja Cole od po 6 limenki po hladnjacima –
08:59
these were common refrigerators for the undergrads.
189
539330
2000
to su bili obični hladnjaci za prodaju pića na fakultetima.
09:01
And I came back to measure what we technically call
190
541330
3000
I došao sam izmjeriti nešto što tehnički nazivamo
09:04
the half-lifetime of Coke -- how long does it last in the refrigerators?
191
544330
4000
poluživot Cole, odnosno koliko je ostala u hladnjaku?
09:08
As you can expect it doesn't last very long; people take it.
192
548330
3000
Kao što možete pretpostaviti nije ostala jako dugo. Ljudi su ih uzimali.
09:11
In contrast, I took a plate with six one-dollar bills,
193
551330
4000
Za razliku, uzeo sam tanjur sa šest novčanica od jednog dolara
09:15
and I left those plates in the same refrigerators.
194
555330
3000
i ostavio te tanjure u istim hladnjacima.
09:18
No bill ever disappeared.
195
558330
1000
Niti jedna novčanica nije nestala.
09:19
Now, this is not a good social science experiment,
196
559330
3000
To nije dobar eksperiment društvenih znanosti,
09:22
so to do it better I did the same experiment
197
562330
3000
pa kako bih to bolje napravio učinio sam isti eksperiment
09:25
as I described to you before.
198
565330
2000
na način koji sam vam opisao ranije.
09:27
A third of the people we passed the sheet, they gave it back to us.
199
567330
3000
Prvoj trećini ljudi smo dali papir, koji su nam vratili.
09:30
A third of the people we passed it to, they shredded it,
200
570330
3000
Drugoj trećini ljudi smo dali papir i nakon što su ga poderali,
09:33
they came to us and said,
201
573330
1000
došli su do nas i rekli
09:34
"Mr. Experimenter, I solved X problems. Give me X dollars."
202
574330
3000
"Gospodine Eksperimentatoru, riješio sam X problema. Dajte mi X dolara."
09:37
A third of the people, when they finished shredding the piece of paper,
203
577330
3000
Zadnja trećina ljudi, kada bi poderala papir,
09:40
they came to us and said,
204
580330
2000
došla bi do nas i rekla,
09:42
"Mr Experimenter, I solved X problems. Give me X tokens."
205
582330
6000
"Gospodine Eksperimentatoru, riješio sam X problema. Dajte mi X žetona."
09:48
We did not pay them with dollars; we paid them with something else.
206
588330
3000
Tim ljudima nismo platili u dolarima. Platili smo im s nečim drugim.
09:51
And then they took the something else, they walked 12 feet to the side,
207
591330
3000
I oni bi uzeli te žetone, odšetali se 3,5 metra u stranu
09:54
and exchanged it for dollars.
208
594330
2000
i razmijenili žetone za dolare.
09:56
Think about the following intuition.
209
596330
2000
Razmišljajte o sljedećoj intuiciji.
09:58
How bad would you feel about taking a pencil from work home,
210
598330
3000
Koliko biste se loše osjećali kada biste ponijeli doma olovku s posla,
10:01
compared to how bad would you feel
211
601330
2000
uspoređujući koliko biste se loše osjećali
10:03
about taking 10 cents from a petty cash box?
212
603330
2000
kada biste uzeli 10 centi iz blagajne?
10:05
These things feel very differently.
213
605330
3000
Te stvari se osjećaju bitno drugačije.
10:08
Would being a step removed from cash for a few seconds
214
608330
3000
Bi li to što ste udaljeni od gotovine nekoliko sekundi
10:11
by being paid by token make a difference?
215
611330
3000
time što ste plaćeni žetonom, napravilo razliku?
10:14
Our subjects doubled their cheating.
216
614330
2000
Naši subjekti su udvostručili njihovo varanje.
10:16
I'll tell you what I think
217
616330
2000
Za minutu ću vam reći što mislim
10:18
about this and the stock market in a minute.
218
618330
2000
o ovom i o tržištu dionica.
10:21
But this did not solve the big problem I had with Enron yet,
219
621330
4000
Ali ovo nije riješilo veliki problem koji sam imao s Enronom,
10:25
because in Enron, there's also a social element.
220
625330
3000
zato jer u Enronu postoji i društveni element.
10:28
People see each other behaving.
221
628330
1000
Ljudi vide jedni druge kako se ponašaju.
10:29
In fact, every day when we open the news
222
629330
2000
U stvari, svaki dan kada otvorimo novine
10:31
we see examples of people cheating.
223
631330
2000
vidimo primjere ljudskog varanja.
10:33
What does this cause us?
224
633330
3000
Što to uzrokuje u nama?
10:36
So, we did another experiment.
225
636330
1000
Napravili smo eksperiment.
10:37
We got a big group of students to be in the experiment,
226
637330
3000
Veliku grupa studenata je sudjelovala u tom eksperimentu
10:40
and we prepaid them.
227
640330
1000
i platili smo im unaprijed.
10:41
So everybody got an envelope with all the money for the experiment,
228
641330
3000
Svatko je dobio omotnicu s novcem za eksperiment,
10:44
and we told them that at the end, we asked them
229
644330
2000
rekli smo im da nam na kraju
10:46
to pay us back the money they didn't make. OK?
230
646330
4000
vrate novac koji nisu zaradili. OK?
10:50
The same thing happens.
231
650330
1000
Ista se stvar dogodila.
10:51
When we give people the opportunity to cheat, they cheat.
232
651330
2000
Kada damo ljudima priliku da varaju, oni varaju.
10:53
They cheat just by a little bit, all the same.
233
653330
3000
Varali su malo, ali varali su.
10:56
But in this experiment we also hired an acting student.
234
656330
3000
U ovom eksperimentu unajmili smo studenta glumca.
10:59
This acting student stood up after 30 seconds, and said,
235
659330
4000
Taj student glumac je ustao nakon 30 sekundi i rekao,
11:03
"I solved everything. What do I do now?"
236
663330
3000
“Ja sam riješio sve. Što da sada radim?”
11:06
And the experimenter said, "If you've finished everything, go home.
237
666330
4000
Čovjek koji je vršio eksperiment rekao je, “Ako ste sve završili, idite kući.”
11:10
That's it. The task is finished."
238
670330
1000
To je to. Zadatak je završen.
11:11
So, now we had a student -- an acting student --
239
671330
4000
Tamo smo imali studenta koji je glumio
11:15
that was a part of the group.
240
675330
2000
da je dio grupe.
11:17
Nobody knew it was an actor.
241
677330
2000
Nitko nije znao da je to glumac.
11:19
And they clearly cheated in a very, very serious way.
242
679330
4000
I očito je varao jako, jako ozbiljno.
11:23
What would happen to the other people in the group?
243
683330
3000
Što će se dogoditi ostalim ljudima u grupi?
11:26
Will they cheat more, or will they cheat less?
244
686330
3000
Hoće li pod utjecaj glumca varati više ili će varati manje?
11:29
Here is what happens.
245
689330
2000
Evo što se dogodilo.
11:31
It turns out it depends on what kind of sweatshirt they're wearing.
246
691330
4000
Ispada da ovisi o tome kakvu su majicu glumci nosili.
11:35
Here is the thing.
247
695330
2000
Evo u čemu je stvar.
11:37
We ran this at Carnegie Mellon and Pittsburgh.
248
697330
3000
Eksperiment smo obavljali na Carnegie Mellonu i Pittsburghu.
11:40
And at Pittsburgh there are two big universities,
249
700330
2000
I na Pittsburghu su dva velika sveučilišta,
11:42
Carnegie Mellon and University of Pittsburgh.
250
702330
3000
Carnegie Mellon i Sveučilište Pittsburgh.
11:45
All of the subjects sitting in the experiment
251
705330
2000
Svi sudionici eksperimenta su bili
11:47
were Carnegie Mellon students.
252
707330
2000
studenti s Carnegie Mellona.
11:49
When the actor who was getting up was a Carnegie Mellon student --
253
709330
4000
Kada je glumac koji se ustao bio student Carnegie Mellon –
11:53
he was actually a Carnegie Mellon student --
254
713330
2000
zapravo i jest bio Carnegie Mellon student –
11:55
but he was a part of their group, cheating went up.
255
715330
4000
a bio je dio njihove grupe, varanje se povećalo.
11:59
But when he actually had a University of Pittsburgh sweatshirt,
256
719330
4000
Ali kada je glumac imao majicu Sveučilišta Pittsburgh,
12:03
cheating went down.
257
723330
2000
varanje se smanjilo.
12:05
(Laughter)
258
725330
3000
(Smijeh)
12:08
Now, this is important, because remember,
259
728330
3000
Ovo je važno, zapamtite,
12:11
when the moment the student stood up,
260
731330
2000
trenutak u kojem se student ustao,
12:13
it made it clear to everybody that they could get away with cheating,
261
733330
3000
postalo je svima jasno da će se izvući s varanjem,
12:16
because the experimenter said,
262
736330
2000
zašto što je čovjek koji vrši eksperimente rekao,
12:18
"You've finished everything. Go home," and they went with the money.
263
738330
2000
“Sve ste završili. Idite kući,” i otišli su sa svojim novcem.
12:20
So it wasn't so much about the probability of being caught again.
264
740330
3000
Nije se više radilo o tome koliko je vjerojatno da ih uhvate.
12:23
It was about the norms for cheating.
265
743330
3000
Radilo se o pravilima varanja.
12:26
If somebody from our in-group cheats and we see them cheating,
266
746330
3000
Ako netko iz naše grupe vara i vidimo ga da vara,
12:29
we feel it's more appropriate, as a group, to behave this way.
267
749330
4000
te mislimo kako je to prikladno onda se i mi kao grupa ponašamo isto tako.
12:33
But if it's somebody from another group, these terrible people --
268
753330
2000
Ali ako vara netko iz druge grupe, ti grozni ljudi --
12:35
I mean, not terrible in this --
269
755330
2000
mislim, nisu oni grozni --
12:37
but somebody we don't want to associate ourselves with,
270
757330
2000
ali netko vara s kim se ne želimo povezati,
12:39
from another university, another group,
271
759330
2000
netko sa drugog sveučilišta, iz druge grupe,
12:41
all of a sudden people's awareness of honesty goes up --
272
761330
3000
odjednom nam se povisi svijest o poštenju –
12:44
a little bit like The Ten Commandments experiment --
273
764330
2000
nešto slično kao eksperiment sa 10 zapovijedi –
12:46
and people cheat even less.
274
766330
4000
ljudi varaju čak i manje.
12:50
So, what have we learned from this about cheating?
275
770330
4000
Što smo naučili iz ovoga o varanju?
12:54
We've learned that a lot of people can cheat.
276
774330
3000
Naučili smo da mnogo ljudi može varati.
12:57
They cheat just by a little bit.
277
777330
3000
Oni varaju samo malo.
13:00
When we remind people about their morality, they cheat less.
278
780330
4000
Kada podsjetimo ljude o njihovoj moralnosti, oni varaju manje.
13:04
When we get bigger distance from cheating,
279
784330
3000
Kada se napravimo veću distancu od varanja,
13:07
from the object of money, for example, people cheat more.
280
787330
4000
od objekta novca na primjer, ljudi varaju više.
13:11
And when we see cheating around us,
281
791330
2000
I kada vidimo varanje oko nas,
13:13
particularly if it's a part of our in-group, cheating goes up.
282
793330
4000
osobito u našoj grupi, varanje se povećava.
13:17
Now, if we think about this in terms of the stock market,
283
797330
3000
Kada razmislimo o ovom u okviru tržišta dionica,
13:20
think about what happens.
284
800330
1000
razmislite što se dogodi.
13:21
What happens in a situation when you create something
285
801330
3000
Što se dogodi u situaciji kada kreirate nešto
13:24
where you pay people a lot of money
286
804330
2000
gdje ljudima platite puno novca
13:26
to see reality in a slightly distorted way?
287
806330
3000
kako bi vidjeli stvarnost na neznatno iskrivljen način?
13:29
Would they not be able to see it this way?
288
809330
3000
Neće li oni biti u mogućnosti vidjeti stvari na isti način?
13:32
Of course they would.
289
812330
1000
Naravno da bi mogli.
13:33
What happens when you do other things,
290
813330
1000
Što se dogodi kada radite druge stvari,
13:34
like you remove things from money?
291
814330
2000
poput toga da odvojite stvari od novca?
13:36
You call them stock, or stock options, derivatives,
292
816330
3000
Zovete ih dionice, ili opcije, derivati,
13:39
mortgage-backed securities.
293
819330
1000
vrijednosnice.
13:40
Could it be that with those more distant things,
294
820330
3000
Može li biti da će uz te udaljene stvari,
13:43
it's not a token for one second,
295
823330
2000
nisu to žetoni na sekundu,
13:45
it's something that is many steps removed from money
296
825330
2000
to je nešto što je mnogo koraka odvojeno od novca
13:47
for a much longer time -- could it be that people will cheat even more?
297
827330
4000
u duljem vremenu – može li biti da će ljudi varati još više?
13:51
And what happens to the social environment
298
831330
2000
I što se događa sa društvenim okruženjem
13:53
when people see other people behave around them?
299
833330
3000
kada ljudi vide druge ljude kako se ponašaju?
13:56
I think all of those forces worked in a very bad way
300
836330
4000
Mislim kako sve te sile zajedno djeluju na jako loš način
14:00
in the stock market.
301
840330
2000
na tržište dionica.
14:02
More generally, I want to tell you something
302
842330
3000
Općenitije, želim vam nešto reći
14:05
about behavioral economics.
303
845330
3000
o biheviorističkoj ekonomiji.
14:08
We have many intuitions in our life,
304
848330
4000
Imamo mnogo intuicija u životu
14:12
and the point is that many of these intuitions are wrong.
305
852330
3000
i stvar je u tome da je velik broj tih intuicija krivo.
14:15
The question is, are we going to test those intuitions?
306
855330
3000
Pitanje je, hoćemo li testirati te intuicije?
14:18
We can think about how we're going to test this intuition
307
858330
2000
Možemo razmisliti o tome kako ćemo testirati te intuicije
14:20
in our private life, in our business life,
308
860330
2000
u našem privatnom i poslovnom životu,
14:22
and most particularly when it goes to policy,
309
862330
3000
a osobito kada razmišljamo o poslovnim politikama,
14:25
when we think about things like No Child Left Behind,
310
865330
3000
kada se sjetimo akcija poput "Nijedno dijete neće biti ostavljeno",
14:28
when you create new stock markets, when you create other policies --
311
868330
3000
kada stvarate nova tržišta dionica, kada stvarate druge politike poput
14:31
taxation, health care and so on.
312
871330
3000
porezne, zdravstvene skrbi i tako dalje.
14:34
And the difficulty of testing our intuition
313
874330
2000
Teškoća u testiranju vlastite intuicije
14:36
was the big lesson I learned
314
876330
2000
bila je velika lekcija koju sam naučio
14:38
when I went back to the nurses to talk to them.
315
878330
2000
kada sam se vratio razgovarati s medicinskim sestrama.
14:40
So I went back to talk to them
316
880330
2000
Vratio sam se razgovarati s njima
14:42
and tell them what I found out about removing bandages.
317
882330
3000
i rekao im što sam saznao o skidanju zavoja.
14:45
And I learned two interesting things.
318
885330
2000
Naučio sam dvije zanimljive stvari.
14:47
One was that my favorite nurse, Ettie,
319
887330
2000
Kao prvo moja omiljena sestra, Ettie,
14:49
told me that I did not take her pain into consideration.
320
889330
4000
mi je rekla kako nisam stavio u razmatranje i njezinu bol.
14:53
She said, "Of course, you know, it was very painful for you.
321
893330
2000
Rekla je, “Naravno, znaš, bilo je veoma bolno za tebe.
14:55
But think about me as a nurse,
322
895330
2000
Ali misli na mene kao sestru,
14:57
taking, removing the bandages of somebody I liked,
323
897330
2000
koja kida zavoje nekome tko joj je drag,
14:59
and had to do it repeatedly over a long period of time.
324
899330
3000
i mora to stalno raditi kroz duži period.
15:02
Creating so much torture was not something that was good for me, too."
325
902330
3000
Spoznaja da uzrokujem bol nije niti dobra za mene.”
15:05
And she said maybe part of the reason was it was difficult for her.
326
905330
5000
I rekla je, možda je dio razloga bio činjenica što je to teško i za nju.
15:10
But it was actually more interesting than that, because she said,
327
910330
3000
Međutim bilo je zanimljivije od toga, jer je rekla,
15:13
"I did not think that your intuition was right.
328
913330
5000
"Nisam mislila da je tvoja intuicija prava.
15:18
I felt my intuition was correct."
329
918330
1000
Osjećala sam kako je moja intuicija točna."
15:19
So, if you think about all of your intuitions,
330
919330
2000
Ako razmislite o svim svojim intuicijama,
15:21
it's very hard to believe that your intuition is wrong.
331
921330
4000
teško je povjerovati da je vaša intuicija loša.
15:25
And she said, "Given the fact that I thought my intuition was right ..." --
332
925330
3000
Rekla je, "Uzimajući u obzir kako sam mislila da je moja intuicija točna..." –
15:28
she thought her intuition was right --
333
928330
2000
mislila je da je njena intuicija točna i
15:30
it was very difficult for her to accept doing a difficult experiment
334
930330
5000
bilo joj je jako teško napraviti teški eksperiment
15:35
to try and check whether she was wrong.
335
935330
2000
kako bi provjerila je li u krivu.
15:37
But in fact, this is the situation we're all in all the time.
336
937330
4000
U stvari, ovo je situacija u kojoj smo svi mi cijelo vrijeme.
15:41
We have very strong intuitions about all kinds of things --
337
941330
3000
Imamo vrlo snažne intuicije o svim stvarima –
15:44
our own ability, how the economy works,
338
944330
3000
našoj sposobnosti, kako ekonomija radi,
15:47
how we should pay school teachers.
339
947330
2000
kako bismo platili učitelje u školi.
15:49
But unless we start testing those intuitions,
340
949330
3000
Ali dok ne počnemo testirati te intuicije,
15:52
we're not going to do better.
341
952330
2000
nećemo početi bolje raditi.
15:54
And just think about how better my life would have been
342
954330
2000
Razmislite samo kako bi moj život bio bolji samo
15:56
if these nurses would have been willing to check their intuition,
343
956330
2000
da su sestre htjele ispitati svoju intuiciju
15:58
and how everything would have been better
344
958330
1000
i kako bi sve bilo bolje da
15:59
if we just start doing more systematic experimentation of our intuitions.
345
959330
5000
počnemo raditi sustavnije eksperimente naše intuicije.
16:04
Thank you very much.
346
964330
2000
Hvala vam puno.
