My relationship with the internet reminds me of the setup
to a clichéd horror movie.
You know, the blissfully happy family moves in to their perfect new home,
excited about their perfect future,
and it's sunny outside and the birds are chirping ...
And then it gets dark.
And there are noises from the attic.
And we realize that that perfect new house isn't so perfect.
When I started working at Google in 2006,
Facebook was just a two-year-old,
and Twitter hadn't yet been born.
And I was in absolute awe of the internet and all of its promise
to make us closer
and smarter
and more free.
But as we were doing the inspiring work of building search engines
and video-sharing sites and social networks,
criminals, dictators and terrorists were figuring out
how to use those same platforms against us.
And we didn't have the foresight to stop them.
Over the last few years, geopolitical forces have come online to wreak havoc.
And in response,
Google supported a few colleagues and me to set up a new group called Jigsaw,
with a mandate to make people safer from threats like violent extremism,
censorship, persecution --
threats that feel very personal to me because I was born in Iran,
and I left in the aftermath of a violent revolution.
But I've come to realize that even if we had all of the resources
of all of the technology companies in the world,
we'd still fail
if we overlooked one critical ingredient:
the human experiences of the victims and perpetrators of those threats.
There are many challenges I could talk to you about today.
I'm going to focus on just two.
The first is terrorism.
So in order to understand the radicalization process,
we met with dozens of former members of violent extremist groups.
One was a British schoolgirl,
who had been taken off of a plane at London Heathrow
as she was trying to make her way to Syria to join ISIS.
And she was 13 years old.
So I sat down with her and her father, and I said, "Why?"
And she said,
"I was looking at pictures of what life is like in Syria,
and I thought I was going to go and live in the Islamic Disney World."
That's what she saw in ISIS.
She thought she'd meet and marry a jihadi Brad Pitt
and go shopping in the mall all day and live happily ever after.
ISIS understands what drives people,
and they carefully craft a message for each audience.
Just look at how many languages
they translate their marketing material into.
They make pamphlets, radio shows and videos
in not just English and Arabic,
but German, Russian, French, Turkish, Kurdish,
Hebrew,
Mandarin Chinese.
I've even seen an ISIS-produced video in sign language.
Just think about that for a second:
ISIS took the time and made the effort
to ensure their message is reaching the deaf and hard of hearing.
It's actually not tech-savviness
that is the reason why ISIS wins hearts and minds.
It's their insight into the prejudices, the vulnerabilities, the desires
of the people they're trying to reach
that does that.
That's why it's not enough
for the online platforms to focus on removing recruiting material.
If we want to have a shot at building meaningful technology
that's going to counter radicalization,
we have to start with the human journey at its core.
So we went to Iraq
to speak to young men who'd bought into ISIS's promise
of heroism and righteousness,
who'd taken up arms to fight for them
and then who'd defected
after they witnessed the brutality of ISIS's rule.
And I'm sitting there in this makeshift prison in the north of Iraq
with this 23-year-old who had actually trained as a suicide bomber
before defecting.
And he says,
"I arrived in Syria full of hope,
and immediately, I had two of my prized possessions confiscated:
my passport and my mobile phone."
The symbols of his physical and digital liberty
were taken away from him on arrival.
And then this is the way he described that moment of loss to me.
He said,
"You know in 'Tom and Jerry,'
when Jerry wants to escape, and then Tom locks the door
and swallows the key
and you see it bulging out of his throat as it travels down?"
And of course, I really could see the image that he was describing,
and I really did connect with the feeling that he was trying to convey,
which was one of doom,
when you know there's no way out.
And I was wondering:
What, if anything, could have changed his mind
the day that he left home?
So I asked,
"If you knew everything that you know now
about the suffering and the corruption, the brutality --
that day you left home,
would you still have gone?"
And he said, "Yes."
And I thought, "Holy crap, he said 'Yes.'"
And then he said,
"At that point, I was so brainwashed,
I wasn't taking in any contradictory information.
I couldn't have been swayed."
"Well, what if you knew everything that you know now
six months before the day that you left?"
"At that point, I think it probably would have changed my mind."
Radicalization isn't this yes-or-no choice.
It's a process, during which people have questions --
about ideology, religion, the living conditions.
And they're coming online for answers,
which is an opportunity to reach them.
And there are videos online from people who have answers --
defectors, for example, telling the story of their journey
into and out of violence;
stories like the one from that man I met in the Iraqi prison.
There are locals who've uploaded cell phone footage
of what life is really like in the caliphate under ISIS's rule.
There are clerics who are sharing peaceful interpretations of Islam.
But you know what?
These people don't generally have the marketing prowess of ISIS.
They risk their lives to speak up and confront terrorist propaganda,
and then they tragically don't reach the people
who most need to hear from them.
And we wanted to see if technology could change that.
So in 2016, we partnered with Moonshot CVE
to pilot a new approach to countering radicalization
called the "Redirect Method."
It uses the power of online advertising
to bridge the gap between those susceptible to ISIS's messaging
and those credible voices that are debunking that messaging.
And it works like this:
someone looking for extremist material --
say they search for "How do I join ISIS?" --
will see an ad appear
that invites them to watch a YouTube video of a cleric, of a defector --
someone who has an authentic answer.
And that targeting is based not on a profile of who they are,
but of determining something that's directly relevant
to their query or question.
During our eight-week pilot in English and Arabic,
we reached over 300,000 people
who had expressed an interest in or sympathy towards a jihadi group.
These people were now watching videos
that could prevent them from making devastating choices.
And because violent extremism isn't confined to any one language,
religion or ideology,
the Redirect Method is now being deployed globally
to protect people being courted online by violent ideologues,
whether they're Islamists, white supremacists
or other violent extremists,
with the goal of giving them the chance to hear from someone
on the other side of that journey;
to give them the chance to choose a different path.
It turns out that often the bad guys are good at exploiting the internet,
not because they're some kind of technological geniuses,
but because they understand what makes people tick.
I want to give you a second example:
online harassment.
Online harassers also work to figure out what will resonate
with another human being.
But not to recruit them like ISIS does,
but to cause them pain.
Imagine this:
you're a woman,
you're married,
you have a kid.
You post something on social media,
and in a reply, you're told that you'll be raped,
that your son will be watching,
details of when and where.
In fact, your home address is put online for everyone to see.
That feels like a pretty real threat.
Do you think you'd go home?
Do you think you'd continue doing the thing that you were doing?
Would you continue doing that thing that's irritating your attacker?
Online abuse has been this perverse art
of figuring out what makes people angry,
what makes people afraid,
what makes people insecure,
and then pushing those pressure points until they're silenced.
When online harassment goes unchecked,
free speech is stifled.
And even the people hosting the conversation
throw up their arms and call it quits,
closing their comment sections and their forums altogether.
That means we're actually losing spaces online
to meet and exchange ideas.
And where online spaces remain,
we descend into echo chambers with people who think just like us.
But that enables the spread of disinformation;
that facilitates polarization.
What if technology instead could enable empathy at scale?
This was the question that motivated our partnership
with Google's Counter Abuse team,
Wikipedia
and newspapers like the New York Times.
We wanted to see if we could build machine-learning models
that could understand the emotional impact of language.
Could we predict which comments were likely to make someone else leave
the online conversation?
And that's no mean feat.
That's no trivial accomplishment
for AI to be able to do something like that.
I mean, just consider these two examples of messages
that could have been sent to me last week.
"Break a leg at TED!"
... and
"I'll break your legs at TED."
(Laughter)
You are human,
that's why that's an obvious difference to you,
even though the words are pretty much the same.
But for AI, it takes some training to teach the models
to recognize that difference.
The beauty of building AI that can tell the difference
is that AI can then scale to the size of the online toxicity phenomenon,
and that was our goal in building our technology called Perspective.
With the help of Perspective,
the New York Times, for example,
has increased spaces online for conversation.
Before our collaboration,
they only had comments enabled on just 10 percent of their articles.
With the help of machine learning,
they have that number up to 30 percent.
So they've tripled it,
and we're still just getting started.
But this is about way more than just making moderators more efficient.
Right now I can see you,
and I can gauge how what I'm saying is landing with you.
You don't have that opportunity online.
Imagine if machine learning could give commenters,
as they're typing,
real-time feedback about how their words might land,
just like facial expressions do in a face-to-face conversation.
Machine learning isn't perfect,
and it still makes plenty of mistakes.
But if we can build technology
that understands the emotional impact of language,
we can build empathy.
That means that we can have dialogue between people
with different politics,
different worldviews,
different values.
And we can reinvigorate the spaces online that most of us have given up on.
When people use technology to exploit and harm others,
they're preying on our human fears and vulnerabilities.
If we ever thought that we could build an internet
insulated from the dark side of humanity,
we were wrong.
If we want today to build technology
that can overcome the challenges that we face,
we have to throw our entire selves into understanding the issues
and into building solutions
that are as human as the problems they aim to solve.
Let's make that happen.
Thank you.
(Applause)
