[BEHIND THE SCREENS[br]Who decides what I see online?]

0:00:08.376,0:00:09.526
Hi, my name’s Taylor.

0:00:09.526,0:00:11.778
I study the internet and journalism

0:00:11.778,0:00:15.977
and how we as citizens receive[br]information about the world.

0:00:17.389,0:00:19.778
In the olden days [br]when people got information,

0:00:19.778,0:00:22.688
it was mostly decided by people.

0:00:22.688,0:00:25.711
There were humans that decided[br]what we needed to know.

0:00:25.711,0:00:30.090
So, when we opened the newspaper or turned[br]on the evening news, it was a person that

0:00:30.090,0:00:32.699
decided what we heard and saw.

0:00:33.300,0:00:36.546
The result of that is[br]that we all knew similar things.

0:00:38.059,0:00:40.742
Now the internet has changed everything.

0:00:41.090,0:00:44.017
When you go online,[br]when you open an application,

0:00:44.486,0:00:47.114
what you see is determined not by a person

0:00:47.489,0:00:48.710
but by a machine.

0:00:49.589,0:00:51.820
And this is awesome in a lot of ways.

0:00:51.984,0:00:56.523
It allows you to use Google Maps,[br]it allows you to order food online,

0:00:56.523,0:01:01.605
it allows you to connect with friends[br]around the world and share information.

0:01:02.000,0:01:07.751
But there are aspects of this machine that[br]we need to think really carefully about

0:01:07.751,0:01:11.618
because they determine[br]the information that we all receive

0:01:11.793,0:01:15.050
as citizens in a society[br]and in a democracy.

0:01:15.489,0:01:17.179
So, when you open up an app

0:01:17.179,0:01:20.531
and you’re shown a picture[br]in your Snapchat feed,

0:01:20.764,0:01:24.420
all of that information[br]is determined by this machine

0:01:24.465,0:01:28.030
and that machine[br]is driven by the incentives

0:01:28.030,0:01:31.321
of the company that owns the website[br]or owns the application.

0:01:32.684,0:01:34.520
And the incentive is for you to spend

0:01:34.520,0:01:38.080
as much time as possible[br]inside that application.

0:01:38.680,0:01:42.250
So, they do things that make you feel[br]very good about being there.

0:01:42.250,0:01:44.467
They allow people to like your photos,

0:01:44.975,0:01:47.943
they show you content[br]that they think you want to see

0:01:48.066,0:01:50.850
that will either make you[br]really happy or really angry,

0:01:50.850,0:01:53.880
that will get an emotional response[br]from you to keep you there.

0:01:54.410,0:01:58.153
That is because they want to show you[br]as many ads as possible when you’re there

0:01:58.153,0:01:59.950
because that is their business model.

0:02:00.897,0:02:04.414
They’re also taking that same opportunity[br]of you being in their app

0:02:04.414,0:02:06.370
to collect data about you.

0:02:06.370,0:02:11.845
And they use these data to create detailed[br]profiles of your life and your behaviour,

0:02:11.845,0:02:16.810
and these profiles can then be used[br]to target more ads back to you.

0:02:17.200,0:02:19.700
And that then determines[br]what you see as well.

0:02:21.470,0:02:25.170
But all of this isn’t just about[br]the business model of these companies,

0:02:25.614,0:02:28.277
it actually has an impact on our democracy

0:02:28.735,0:02:34.289
because what we each see on the internet[br]is highly customized to us,

0:02:34.990,0:02:41.010
to what we like, to what we believe,[br]to what we want to see or want to believe.

0:02:41.523,0:02:43.498
And that means that as a society,

0:02:43.756,0:02:47.500
we no longer all have[br]a shared set of knowledge

0:02:47.500,0:02:51.134
which is hard for a democracy[br]that requires us to work together

0:02:51.134,0:02:54.880
and know the same things to make[br]decisions about our lives together.

0:02:55.391,0:02:57.030
When we all know different things

0:02:57.030,0:03:01.059
and we’re all being siloed into[br]our own little bubbles of information,

0:03:01.567,0:03:04.860
it’s incredibility difficult for us[br]to get along with one another.

0:03:04.860,0:03:07.670
We have no shared experience[br]or shared knowledge.

0:03:08.241,0:03:12.810
So, I think it’s really important that we[br]think critically about the information we

0:03:12.810,0:03:17.113
receive online and about the companies[br]and structures that determine

0:03:17.385,0:03:19.219
what we see on the internet.
