Now, this is Joanna.

Joanna works at a university in Poland.

And one Saturday morning at 3am,

she got up, packed her rucksack

and traveled more than
a thousand kilometers,

only to have a political argument

with a stranger.

His name is Christof,
and he's a customer manager from Germany.

And the two had never met before.

They only knew that they were
totally at odds over European politics,

over migration, or the relationship
to Russia or whatever.

And they were arguing for almost one day.

And after that, Joanna sent me
a somewhat irritating email.

"That was really cool, and I enjoyed
every single minute of it!"

(Laughter)

So these are Tom from the UK
and Nils from Germany.

They also were strangers,

and they are both supporters
of their local football team,

as you may imagine, Borussia Dortmund
and Tottenham Hotspurs.

And so they met on the very spot
where football roots were invented,

on some field in Cambridge.

And they didn't argue about football,

but about Brexit.

And after talking for many hours
about this contentious topic,

they also sent a rather unexpected email.

"It was delightful, and we both
enjoyed it very much."

(Laughter)

So in spring 2019,

more than 17,000 Europeans
from 33 countries

signed up to have a political argument.

Thousands crossed their borders to meet
a stranger with a different opinion,

and they were all part of a project
called "Europe Talks."

Now, talking about politics
amongst people with different opinions

has become really difficult,

not only in Europe.

Families are splitting,
friends no longer talk to each other.

We stay in our bubbles.

And these so-called filter bubbles
are amplified by social media,

but they are not,
in the core, a digital product.

The filter bubble has always been there.

It's in our minds.

As many studies repeatedly have shown,

we, for example, ignore effects
that contradict our convictions.

So correcting fake news
is definitely necessary,

but it's not sufficient
to get a divided society

to rethink itself.

Fortunately, according to
at least some research,

there may be a simple way
to get a new perspective:

a personal one-on-one discussion

with someone who doesn't
have your opinion.

It enables you to see
the world in a new way,

through someone else's eyes.

Now, I'm the editor of "ZEIT ONLINE,"

one of the major digital
news organizations in Germany.

And we started what became "Europe Talks"
as a really modest editorial exercise.

As many journalists,

we were impressed by Trump and by Brexit,

and Germany was getting divided, too,
especially over the issue of migration.

So the arrival of more than
a million refugees in 2015 and 2016

dominated somewhat the debate.

And when we were thinking
about our own upcoming election in 2017,

we definitely knew that we had to reinvent
the way we were dealing with politics.

So digital nerds that we are,

we came up with obviously
many very strange digital product ideas,

one of them being a Tinder for politics --

(Laughter)

a dating platform for political opposites,

a tool that could help get people
together with different opinions.

And we decided to test it

and launched what techies would call
a "minimum viable product."

So it was really simple.

We called it "Deutschland spricht" --
"Germany Talks" --

and we started with that in May 2017.

And it was really simple.

We used mainly Google Forms,

a tool that each and every one of us here
can use to make surveys online.

And everywhere in our content,
we embedded simple questions like this:

"Did Germany take in too many refugees?"

You click yes or no.

We asked you more questions, like,
"Does the West treat Russia fairly?"

or, "Should gay couples
be allowed to marry?"

And if you answered all these questions,
we asked one more question:

"Hey, would you like to meet a neighbor
who totally disagrees with you?"

(Laughter)

So this was a really simple experiment
with no budget whatsoever.

We expected some
hundred-ish people to register,

and we planned to match them
by hand, the pairs.

And after one day,
1,000 people had registered.

And after some weeks,
12,000 Germans had signed up

to meet someone else
with a different opinion.

So we had a problem.

(Laughter)

We hacked a quick and dirty algorithm

that would find
the perfect Tinder matches,

like people living as close as possible
having answered the questions

as differently as possible.

We introduced them via email.

And, as you may imagine,
we had many concerns.

Maybe no one would show up in real life.

Maybe all the discussions
in real life would be awful.

Or maybe we had an axe murderer
in our database.

(Laughter)

But then, on a Sunday in June 2017,

something beautiful happened.

Thousands of Germans met in pairs
and talked about politics peacefully.

Like Anno.

He's a former policeman who's against --
or was against -- gay marriage,

and Anne, she's an engineer who lives
in a domestic partnership

with another woman.

And they were talking
for hours about all the topics

where they had different opinions.

At one point, Anno told us later,

he realized that Anne was hurt
by his statements about gay marriage,

and he started to question
his own assumptions.

And after talking for three hours,

Anne invited Anno to her summer party,

and today, years later,

they still meet from time to time
and are friends.

So our algorithm matched,
for example, this court bailiff.

He's also a spokesperson of the right-wing
populist party AfD in Germany,

and this counselor for pregnant women.

She used to be an active member
of the Green Party.

We even matched this professor
and his student.

(Laughter)

It's an algorithm.

(Laughter)

We also matched a father-in-law
and his very own daughter-in-law,

because, obviously, they live close by
but have really different opinions.

So as a general rule,

we did not observe, record,
document the discussions,

because we didn't want
people to perform in any way.

But I made an exception.

I took part myself.

And so I met in my trendy Berlin
neighborhood called Prenzlauer Berg,

I met Mirko.

This is me talking to Mirko.
Mirko didn't want to be in the picture.

He's a young plant operator,

and he looked like
all the hipsters in our area,

like with a beard and a beanie.

We were talking for hours,
and I found him to be a wonderful person.

And despite the fact that we had
really different opinions

about most of the topics --

maybe with the exception
of women's rights,

where I couldn't comprehend
his thoughts --

it was really nice.

After our discussion, I Googled Mirko.

And I found out that in his teenage years,
he used to be a neo-Nazi.

So I called him and asked,

"Hey, why didn't you tell me?"

And he said, "You know, I didn't tell you
because I want to get over it.

I just don't want
to talk about it anymore."

I thought that people with
a history like that could never change,

and I had to rethink my assumptions,

as did many of the participants
who sent us thousands of emails

and also selfies.

No violence was recorded whatsoever.

(Laughter)

And we just don't know
if some of the pairs got married.

(Laughter)

But, at least, we were really excited
and wanted to do it again,

especially in version 2.0,

wanted to expand the diversity
of the participants,

because obviously in the first round,
they were mainly our readers.

And so we embraced our competition

and asked other media outlets to join.

We coordinated via Slack.

And this live collaboration
among 11 major German media houses

was definitely a first in Germany.

The numbers more than doubled:
28,000 people applied this time.

And the German president --

you see him here
in the center of the picture --

became our patron.

And so, thousands of Germans met again
in the summer of 2018

to talk to someone else
with a different opinion.

Some of the pairs we invited
to Berlin to a special event.

And there, this picture was taken,

until today my favorite symbol
for "Germany Talks."

You see Henrik,
a bus driver and boxing trainer,

and Engelbert, the director
of a children's help center.

They answered all of the seven questions
we asked differently.

They had never met before this day,

and they had a really intensive discussion

and seemed to get along anyway

with each other.

So this time we also wanted to know

if the discussion would have
any impact on the participants.

So we asked researchers
to survey the participants.

And two-thirds of the participants said
that they learned something

about their partner's attitudes.

Sixty percent agreed
that their viewpoints converged.

The level of trust in society
seemed also higher after the event,

according to the researchers.

Ninety percent said that
they enjoyed their discussion.

Ten percent said they didn't
enjoy their discussion,

eight percent only because,
simply, their partner didn't show up.

(Laughter)

After "Germany Talks," we got approached
by many international media outlets,

and we decided this time to build
a serious and secure platform.

We called it "My Country Talks."

And in this short period of time,
"My Country Talks" has already been used

for more than a dozen
local and national events

like "Het grote gelijk" in Belgium
or "Suomi puhuu" in Finland

or "Britain Talks" in the UK.

And as I mentioned at the beginning,
we also launched "Europe Talks,"

together with 15
international media partners,

from the "Financial Times" in the UK
to "Helsingin Sanomat" in Finland.

Thousands of Europeans met
with a total stranger

to argue about politics.

So far, we have been approached
by more than 150 global media outlets,

and maybe someday there will be
something like "The World Talks,"

with hundreds of thousands
of participants.

But what matters here are not the numbers,

obviously.

What matters here is ...

Whenever two people meet
to talk in person for hours

without anyone else listening,

they change.

And so do our societies.

They change little by little,
discussion by discussion.

What matters here is that we relearn

how to have these
face-to-face discussions,

without anyone else listening,

with a stranger.

Not only with a stranger
we are introduced to

by a Tinder for politics,

but also with a stranger in a pub
or in a gym or at a conference.

So please meet someone

and have an argument

and enjoy it very much.

Thank you.

(Applause)

Wow!

(Applause)
