0:12 - 0:14Mariano Sigman:
So this day is about trust, -
0:14 - 0:19and it happens in a quite peculiar moment
in which, I guess we all know, -
0:19 - 0:22societies have become quite polarized.
-
0:22 - 0:25And there are certain topics
that have become very difficult to talk, -
0:25 - 0:27we are very distant with people,
-
0:27 - 0:29and it's become really with a feeling
-
0:29 - 0:31that's difficult
to talk about these topics. -
0:31 - 0:35And Dan I wanted to think
and to reflect about these, -
0:35 - 0:37but instead of doing
in the traditional way, -
0:37 - 0:41which is on this stage, in which,
like, maybe we think about these, -
0:41 - 0:42we come with a great idea,
-
0:42 - 0:44we pack it in a story,
and we give it to you, -
0:44 - 0:50we asked, what if we try to construct
this idea here, together, -
0:50 - 0:53and we began thinking
about this in this place. -
0:53 - 0:55And so we are scientists,
-
0:55 - 0:58and so we love to do experiments -
-
0:58 - 1:00in the lab, outside, we live,
actually doing experiments; -
1:00 - 1:02I think that's fair to say.
-
1:02 - 1:06And so actually the proposal
is let's do one experiment here, now, -
1:06 - 1:07altogether.
-
1:07 - 1:11And so to begin the experiment,
this is not really high technology, -
1:11 - 1:14it's based on pencil and paper.
-
1:14 - 1:19And if you look just behind your chairs,
if you put your hand, -
1:19 - 1:22you'll see that all of you
should have, I hope, -
1:22 - 1:24one envelope like this.
-
1:25 - 1:27Dan Ariely: Don't open it yet.
-
1:28 - 1:29MS: Just go like this
-
1:29 - 1:32because usually the sound of papers
is very - collective sound of paper -
1:32 - 1:34is very good, so just ... (DA: Yay)
-
1:34 - 1:35Very well.
-
1:35 - 1:36DA: Very good.
-
1:36 - 1:39Anybody doesn't have an envelope?
-
1:39 - 1:41MS: Okay.
-
1:44 - 1:46DA: Okay.
-
1:46 - 1:47MS: We can start.
-
1:47 - 1:48DA: So let's start. So ...
-
1:50 - 1:52please open the envelope.
-
1:52 - 1:54MS: First page.
-
1:55 - 1:57Where it says, "TEDxperiments,"
that's the first page. -
1:57 - 1:59That's where we will begin.
-
2:02 - 2:03DA: Do they have a pen?
-
2:03 - 2:05MS: Well, you should have a pen.
-
2:05 - 2:08If you don't have a pen,
then you can ask a pen to your neighbor. -
2:08 - 2:11I mean, I'm sure there are enough pens
that we can do this together. -
2:11 - 2:13Because you were given pens in the bag.
-
2:13 - 2:15DA: In the bag there's a pen, yeah?
-
2:15 - 2:19MS: As we said, this is a real experiment;
it is not demonstration. -
2:19 - 2:21So we will use the data collected here
-
2:21 - 2:24to learn something about
what's going to happen here. -
2:24 - 2:26So for this we need you to sign
-
2:26 - 2:28that you're willing
to be part of this experiment. -
2:28 - 2:29This is how science goes.
-
2:29 - 2:32So if you're willing to do this,
just say "Yes" here - Sim, -
2:32 - 2:35and if not you say "No" and you write
your age and your gender, -
2:35 - 2:39and we move to page number two.
-
2:39 - 2:41DA: Everybody finished?
-
2:41 - 2:44Anybody has not finished
with page number one? -
2:47 - 2:48Okay.
-
2:49 - 2:51Make sure you get a pen.
-
2:51 - 2:53Finish page number one.
-
2:55 - 2:57Okay.
-
2:59 - 3:00Next page.
-
3:04 - 3:06There's some things
written in Portuguese here. -
3:06 - 3:09MS: I should - I'm closer
to Portuguese than you, right? -
3:09 - 3:10DA: Yeah.
-
3:10 - 3:13MS: Well, actually,
not geographically, but maybe - -
3:13 - 3:15So I'm going to make
my best effort to read them. -
3:15 - 3:18You see there are five questions.
You can read them yourselves. -
3:18 - 3:20And those are five questions
-
3:20 - 3:22where we ask you to say
where you agree with these or not, -
3:22 - 3:24or where you feel you can have an opinion.
-
3:24 - 3:26We'll go relatively fast with these.
-
3:26 - 3:27So the first question is:
-
3:27 - 3:32(Portuguese) "There should be
quotas for women in Parliament." -
3:32 - 3:34I have a bit of a Brazilian,
you know, we're closer to - -
3:34 - 3:37I'm Argentinian, what could I do?
-
3:38 - 3:40So either you agree, you don't agree,
-
3:40 - 3:43or you just don't want to answer
-
3:43 - 3:45or don't feel like
you have an answer for that. -
3:46 - 3:47So as you see, we chose things
-
3:47 - 3:50where hopefully there is
some difference between us. -
3:50 - 3:51The second one is:
-
3:51 - 3:54(Portuguese) "Drugs
should be decriminalized." -
3:54 - 3:56So (Portuguese) Yes, No,
-
3:56 - 3:59(Portuguese) or Not sure / No response.
-
3:59 - 4:00DA: So this is something about drugs.
-
4:00 - 4:01MS: This, yeah.
-
4:01 - 4:03DA: It's a good question.
-
4:03 - 4:04MS: We'll see.
-
4:05 - 4:07Question number three.
-
4:07 - 4:11(Portuguese) "University
should be free for everybody." -
4:12 - 4:16(Portuguese) Yes, No,
or Not sure / No response. -
4:17 - 4:18This is about university.
-
4:18 - 4:20DA: Should university
be free for everybody? -
4:20 - 4:22MS: Yeah, that's the question.
-
4:22 - 4:23Please don't answer it.
-
4:23 - 4:24DA: No.
-
4:24 - 4:27MS: Now, question number four.
-
4:28 - 4:33(Portuguese) "Everyone should use
public transportation instead of cars." -
4:34 - 4:37DA: Should we all [use]
public transportation instead of cars? -
4:37 - 4:39MS: You know Portuguese, man!
DA: Yeah, yeah. -
4:39 - 4:43MS: (Portuguese) Yes, No, or Not Sure -
-
4:43 - 4:45Again - well, you know.
-
4:45 - 4:46You want to read the fifth one?
-
4:46 - 4:48DA: No.
MS: Okay. -
4:48 - 4:49(Laughter)
-
4:49 - 4:54MS: (Portuguese) "Smoking
should be forbidden in all public places." -
4:54 - 4:55DA: Something about smoking.
-
4:55 - 4:59MS: (Portuguese) Yes, No,
Not sure / No response. -
4:59 - 5:04It says, "Smoking should be forbidden
in all public places." -
5:04 - 5:06DA: Great. Everybody finished?
-
5:07 - 5:08Great.
-
5:08 - 5:11Now comes the tricky part.
-
5:12 - 5:16You have a number on your envelope.
-
5:16 - 5:20MS: It's also on the first page
if you lost the envelope. -
5:20 - 5:25DA: And somebody else
has the same number on their envelope. -
5:25 - 5:30And what you're supposed to do
is to find that person. -
5:30 - 5:33Let us show you how you find them.
-
5:34 - 5:35You say, "290!"
-
5:35 - 5:36MS: 290!
-
5:36 - 5:38DA and MS: Ahhh!
-
5:38 - 5:41DA: Okay, wait. So you find a person -
-
5:43 - 5:46Come on! Stand up!
-
5:56 - 5:59They should be not too far from you.
-
6:04 - 6:06If you don't find that person, stand up.
-
6:06 - 6:09If you find the person, sit down.
-
6:10 - 6:13If you haven't found the person, stand up
-
6:13 - 6:19and show it around
until you find the person. -
6:21 - 6:23If you find the person, sit down.
-
6:23 - 6:24You found it?
-
6:24 - 6:27MS: Look, please, please, hey, pspsps.
-
6:27 - 6:31We need some silence, some silence.
-
6:31 - 6:34People! Hey, hey!
-
6:39 - 6:40Please, please, silence!
-
6:40 - 6:41DA: I have a trick.
-
6:41 - 6:45The secret of having good sex ...
-
6:45 - 6:47(Laughter)
-
6:49 - 6:53MS: People, please, please, please
make some silence here. -
6:53 - 6:54DA: Let me try again.
-
6:54 - 6:56A guy goes to the rabbi,
-
6:56 - 7:02and he says, "Rabbi,
I think my wife is trying to kill me. -
7:02 - 7:05Would you talk to her
and find out if that's the case?" -
7:05 - 7:06No, it doesn't work.
-
7:06 - 7:07MS: No.
-
7:07 - 7:09Anal sex!
-
7:09 - 7:10(Laughter)
-
7:10 - 7:13DA: Okay! Quiet!
-
7:13 - 7:17MS: That's always - Okay,
you know, you should - hey! -
7:17 - 7:22People that don't have a partner,
you silently go to the [aisle], -
7:22 - 7:24you find someone else,
-
7:24 - 7:25and you just invent a number,
-
7:25 - 7:28and you write down the number
for the two envelopes. -
7:28 - 7:30Once you find a partner,
-
7:30 - 7:34from now on, you have four minutes
to do the following thing. -
7:34 - 7:36Please pay attention.
-
7:36 - 7:41You have to discuss
about these five questions, -
7:41 - 7:42freely.
-
7:42 - 7:45You can discuss one of them,
three of them, four of them, -
7:45 - 7:47the one you like the most.
-
7:47 - 7:50And you have to write down -
pay attention to this: -
7:50 - 7:56In part three, you have to write down
the opinion, the responses, -
7:56 - 7:59of the person you are talking with.
-
7:59 - 8:01So here is part three,
-
8:01 - 8:02and you will have to -
-
8:02 - 8:04Sorry, in part two -
-
8:04 - 8:06no in part two.
-
8:06 - 8:10In part two, you will have to respond
the answers of your partners. -
8:10 - 8:16So you have four minutes from now on
to talk with the other person -
8:16 - 8:19and try to choose
the more sensitive issues. -
8:19 - 8:20Your time.
-
8:20 - 8:22Now you can talk all what you want. Start!
-
8:22 - 8:23DA: Go!
-
8:25 - 8:28(Audience chatter)
-
9:44 - 9:47Audience member:
(Portuguese) Hey Marcos, which one? -
9:47 - 9:49Marcos: (Portuguese)
Decriminalizing drugs. -
9:49 - 9:51Audience member: Ah!
-
9:51 - 9:52(Portuguese) Let's do it.
-
9:52 - 9:53Marcos: (Portuguese) How crazy.
-
9:53 - 9:55(Laughter)
-
9:55 - 9:59Audience member: (Portuguese)
To me, the TED audience will agree on ... -
10:17 - 10:20[3 minutes later ...]
-
10:22 - 10:28DA: Ehm, we want to make sure you write
the opinions of the other person -
10:28 - 10:29on part two.
-
10:30 - 10:33So in part one,
you write your own opinions. -
10:34 - 10:39In part two, you write
the other person's opinion. -
10:39 - 10:41And once you finish that,
-
10:42 - 10:46in the bottom,
there's a short description -
10:46 - 10:50of how you should end your discussion.
-
10:50 - 10:56So please follow these instructions
of how to end this discussion, -
10:56 - 10:57and then -
-
10:59 - 11:01Follow the instrucitons.
-
11:04 - 11:06MS: Let's see two groups.
-
11:07 - 11:09(Audience chatter)
-
11:16 - 11:17DA: Okay.
-
11:18 - 11:22And now, please fill part number three.
-
11:23 - 11:25Fill out part number three.
-
11:25 - 11:28MS: Part number three is private.
-
11:28 - 11:29DA: Private.
-
11:29 - 11:33MS: Do it alone. Each one alone.
Groups now are over. -
11:33 - 11:36You do it alone, and you fill part three.
-
11:36 - 11:39DA: Part three, please fill it out.
-
11:39 - 11:42And once you filled it out,
-
11:42 - 11:43take this,
-
11:43 - 11:48and put it back in your envelope.
-
11:50 - 11:54And please pass the envelopes forward.
-
12:03 - 12:05Quietly.
-
12:07 - 12:09Okay, so -
-
12:13 - 12:16So here is the question:
-
12:19 - 12:22No, no, no. Don't seal it.
Don't worry. It's not that secret. -
12:27 - 12:31Okay, so, why did we do this?
-
12:31 - 12:32MS: Why did we do it?
-
12:32 - 12:34DA: Why did we do it?
-
12:34 - 12:39MS: So, as you can see, these questions
are questions where people have hopefully, -
12:39 - 12:43I mean maybe in some of these groups,
you agreed completely; -
12:43 - 12:47in some of these groups,
maybe there were a lot of differences. -
12:47 - 12:50And as you may imagine,
as you may imagine, -
12:50 - 12:54we tend to like, we tend to trust,
-
12:54 - 12:58we tend to think
that people that think like us -
12:58 - 13:01are actually better,
more attractive, more trustable. -
13:01 - 13:03So we wanted to ask this question.
-
13:03 - 13:07In the very end, you all responded
questions about liking the other person. -
13:07 - 13:10But there was a bit of a trick.
-
13:10 - 13:11DA: So wait.
-
13:11 - 13:17So the first thing is we wanted
to replicate previous results -
13:18 - 13:22that basically say
when people are more similar to us, -
13:22 - 13:24we like them more.
-
13:24 - 13:27And there's actually
quite a few interesting nuances. -
13:27 - 13:29MS: Yeah, so -
DA: What you found? -
13:29 - 13:32MS: So we've done - I mean, this is
the second time we did this experiment. -
13:32 - 13:35We did the first in Argentina
with 10,000 people, -
13:35 - 13:37and now we are doing it again
here in Portugal. -
13:37 - 13:40And what we are trying
to show, the first thing - -
13:40 - 13:43There are two things about this experiment
that we are trying to test - -
13:43 - 13:46there are questions, there are hypotheses
that we would like to respond. -
13:46 - 13:48The first one is you may have seen
-
13:48 - 13:50that some of you,
when you finished the discussion, -
13:50 - 13:52you did something like this.
-
13:53 - 13:56And some of you did something
-
13:57 - 13:58like this.
-
13:58 - 14:00And it happens to be not quite the same.
-
14:00 - 14:01We asked -
-
14:01 - 14:03and we ask this question
as always in science -
14:03 - 14:07because we have reason to believe
that if we hug the other person, -
14:07 - 14:11can this make us immune to this bias
-
14:11 - 14:14by which we do not accept
so much the differences? -
14:14 - 14:16And it seems to be,
this is what we are finding, -
14:16 - 14:18this is what we would like
to confirm here - -
14:18 - 14:20DA: Too much for me,
let's get a little far. -
14:20 - 14:22MS: This is what
we are trying to confirm here, -
14:22 - 14:25that once we hug the other person,
-
14:25 - 14:26we're more open,
-
14:26 - 14:29and we're willing to trust
the people that think like us -
14:29 - 14:32but also the people
that think differently for us. -
14:32 - 14:35DA: So the question is whether the hug -
-
14:35 - 14:39it basically bonds us
and can bridge differences. -
14:39 - 14:42Now, lots of those things
about our differences -
14:42 - 14:44are nothing that are explicit.
-
14:44 - 14:49Before the session, there was
this beautiful video from Denmark. -
14:49 - 14:53Right? About all the people
with the differences and so on. -
14:53 - 14:55I was in Denmark a couple of months ago,
-
14:55 - 14:59and there's a very funny thing
happening in Denmark, -
14:59 - 15:05which is kids start learning Danish
about two years slower -
15:05 - 15:07than they learned 20 years ago.
-
15:07 - 15:11For some reason,
Danish kids are slower now -
15:11 - 15:12picking up language.
-
15:12 - 15:15And the question is why.
Why does it happen? -
15:15 - 15:17It doesn't happen in Norway.
-
15:17 - 15:19It only happens in Denmark.
-
15:20 - 15:22And what they found is that the reason
-
15:22 - 15:27is that the parents are speaking faster
and swallow their words. -
15:27 - 15:30They make it harder
for the kids to learn language. -
15:30 - 15:33Again, why would parents do that?
-
15:33 - 15:35And the current theory
-
15:35 - 15:39is that it's a barrier against immigrants.
-
15:39 - 15:41So what the Danish
are doing - not explicitly, -
15:41 - 15:45it's not that the Danish say explicitly,
"We hate foreigners; let's do it," -
15:46 - 15:48but as a society,
they created a mechanism -
15:48 - 15:51that creates barrier for new people.
-
15:51 - 15:54And the barrier is that
it's harder to learn Danish - -
15:54 - 15:57they also make it harder
for their own kids -
15:57 - 15:58to learn Danish in the process -
-
15:58 - 16:01and it's an implicit barrier.
-
16:01 - 16:06So the question we wanted to ask here,
and we'll figure out the results, -
16:06 - 16:09is whether some kind
of physical connection -
16:10 - 16:12helps us bridge the gaps.
-
16:12 - 16:15We've tried all kinds of things
in the past about bridging gaps, -
16:15 - 16:17including the four-minute
discussion that you have -
16:17 - 16:20and the results
were very impressive, right? -
16:20 - 16:23The results show that
even a four-minute diuscussion -
16:23 - 16:27on things that people really disagree with
helps bridge the gaps. -
16:27 - 16:29Now we're going to try to figure out
-
16:29 - 16:31whether it's also about
physical proximity, -
16:31 - 16:32whether it helps.
-
16:32 - 16:34MS: So again, this seems to be the case.
-
16:34 - 16:37And sometimes, you know, science
does not have to be rocket science. -
16:37 - 16:41I mean, giving a hug
is not a lot of technology, -
16:41 - 16:42but maybe it's quite powerful,
-
16:42 - 16:44and this is what we are trying to show,
-
16:44 - 16:47that people become much more tolerant
once they've done so. -
16:47 - 16:50And to me, you know,
I watch a lot of football; this is - -
16:50 - 16:52I mean, what can I do, I'm Argentinian.
-
16:52 - 16:55And people that watch a lot of football,
-
16:55 - 16:57of course, there is not
a lot of good football. -
16:57 - 17:00So if you watch a lot of football,
you watch some good football -
17:00 - 17:02and a lot of bad football.
-
17:02 - 17:03DA: Argentianian, you say.
-
17:03 - 17:05MS: Yeah, Argentinian football -
-
17:05 - 17:06bad football.
-
17:06 - 17:12And so, often, I'm watching this game
which is completely irrelevant, -
17:12 - 17:16like a second division game
in the Luxembourg League. -
17:16 - 17:19I mean, imagine something
more irrelevant than that. -
17:19 - 17:22And it's like a game
in the middle of the championship - -
17:22 - 17:24irrelevant because it's in
the middle of a championship. -
17:24 - 17:26And the game is already closed -
-
17:26 - 17:28there's nothing that will change.
-
17:28 - 17:29And there is a goal there.
-
17:29 - 17:31So you see how irrelevant this is.
-
17:31 - 17:34It's the most irrelevant league,
the most irrelevant game, -
17:34 - 17:35the most irrelevant moment.
-
17:35 - 17:37But the players, they hug each other
-
17:37 - 17:40like it would be the most important
moment in the universe. -
17:40 - 17:43It's like you see them
and you go, What's going on? -
17:43 - 17:45And so when I saw that, I reflected,
-
17:45 - 17:47I know how it's for you
in your professions. -
17:47 - 17:49I'm a scientist;
I've done science for 20 years, -
17:49 - 17:52and I think I've never hugged
any of my colleagues. -
17:52 - 17:54I mean, I've had very good moments,
good discoveries, good - -
17:54 - 17:57I mean, moments of thought,
good moments of enthusiasm. -
17:57 - 17:59But I've never said, You know what,
-
17:59 - 18:00this is so important
-
18:00 - 18:03that we should hug each other
in this moment of intense bonding -
18:03 - 18:05that actually football players do.
-
18:05 - 18:08And so maybe what we should hear
is that this is quite important, -
18:08 - 18:11and so we proposed here
maybe to change that. -
18:11 - 18:14After 20 years, with one
of my friends and colleagues, -
18:14 - 18:18we're going to change that,
and we invite you to actually hug - -
18:18 - 18:20DA: Let's demonstrate.
Let's demonstrate. -
18:20 - 18:21MS: Physical contact can be like this ...
-
18:21 - 18:23or it can be ... like this.
-
18:23 - 18:26So you choose [Inaudible]
-
18:26 - 18:28Both: Oooooh.
-
18:29 - 18:31Rrrrghhhhh.
-
18:31 - 18:32(Laughter)
-
18:32 - 18:33(Applause)
-
18:35 - 18:36DA: Okay, now -
-
18:36 - 18:38MS: Everybody do the same.
-
18:40 - 18:41Strong hug. Come on.
-
18:41 - 18:42DA: Real hug.
-
18:42 - 18:44A real hug.
-
18:45 - 18:47(Audience chatter)
-
18:50 - 18:53DA: I can feel the oxytocin.
-
19:04 - 19:05Thank you very much,
-
19:05 - 19:08and we will report the result
of the experiment soon. -
19:08 - 19:10MS: (Portuguese) Thank you! Bye!
-
19:10 - 19:12(Applause) (Cheers)

Dan Ariely, James B. Duke Professor of Psychology & Behavioral Economics at Duke University, is dedicated to answering questions in order to help people live more sensible – if not rational – lives. His interests span a wide range of behaviors, and his sometimes unusual experiments are consistently interesting, amusing and informative, demonstrating profound ideas that fly in the face of common wisdom. He is a founding member of the Center for Advanced Hindsight, co-creator of the film documentary (Dis)Honesty: The Truth About Lies, and a three-time New York Times bestselling author. His books include Predictably Irrational, The Upside of Irrationality, The Honest Truth About Dishonesty, Irrationally Yours, Payoff, and Dollars and Sense. In 2013 Bloomberg recognized Dan as one of Top 50 Most Influential thinkers. He also has a bi-weekly advice column in the Wall Street Journal called “Ask Ariely.”
