0:00:01.096,0:00:05.810
In the months following[br]the 2009 presidential election in Iran,

0:00:05.834,0:00:08.728
protests erupted across the country.

0:00:09.685,0:00:12.581
The Iranian government[br]violently suppressed

0:00:12.605,0:00:16.584
what came to be known[br]as the Iranian Green Movement,

0:00:16.608,0:00:18.661
even blocking mobile signals

0:00:18.685,0:00:21.399
to cut off communication[br]between the protesters.

0:00:22.316,0:00:26.985
My parents, who emigrated[br]to the United States in the late 1960s,

0:00:27.009,0:00:28.803
spend substantial time there,

0:00:28.827,0:00:31.980
where all of my large,[br]extended family live.

0:00:32.832,0:00:35.961
When I would call my family in Tehran

0:00:35.985,0:00:39.437
during some of the most violent[br]crackdowns of the protest,

0:00:39.461,0:00:42.713
none of them dared discuss[br]with me what was happening.

0:00:43.196,0:00:46.725
They or I knew to quickly steer[br]the conversation to other topics.

0:00:47.163,0:00:50.543
All of us understood[br]what the consequences could be

0:00:50.567,0:00:53.107
of a perceived dissident action.

0:00:54.095,0:00:57.564
But I still wish I could have known[br]what they were thinking

0:00:57.588,0:00:59.006
or what they were feeling.

0:01:00.217,0:01:01.610
What if I could have?

0:01:02.149,0:01:03.300
Or more frighteningly,

0:01:03.324,0:01:06.085
what if the Iranian government could have?

0:01:06.695,0:01:09.939
Would they have arrested them[br]based on what their brains revealed?

0:01:10.933,0:01:13.877
That day may be closer than you think.

0:01:14.527,0:01:18.338
With our growing capabilities[br]in neuroscience, artificial intelligence

0:01:18.362,0:01:20.065
and machine learning,

0:01:20.089,0:01:24.164
we may soon know a lot more[br]of what's happening in the human brain.

0:01:25.083,0:01:28.393
As a bioethicist, a lawyer, a philosopher

0:01:28.417,0:01:30.284
and an Iranian-American,

0:01:30.308,0:01:34.095
I'm deeply concerned[br]about what this means for our freedoms

0:01:34.119,0:01:36.290
and what kinds of protections we need.

0:01:36.993,0:01:40.453
I believe we need[br]a right to cognitive liberty,

0:01:40.477,0:01:43.369
as a human right[br]that needs to be protected.

0:01:43.772,0:01:46.415
If not, our freedom of thought,

0:01:46.439,0:01:49.463
access and control over our own brains

0:01:49.487,0:01:52.328
and our mental privacy will be threatened.

0:01:53.698,0:01:54.856
Consider this:

0:01:54.880,0:01:58.194
the average person thinks[br]thousands of thoughts each day.

0:01:58.697,0:01:59.848
As a thought takes form,

0:01:59.872,0:02:04.928
like a math calculation[br]or a number, a word,

0:02:04.952,0:02:07.837
neurons are interacting in the brain,

0:02:07.861,0:02:10.949
creating a miniscule electrical discharge.

0:02:11.713,0:02:15.165
When you have a dominant[br]mental state, like relaxation,

0:02:15.189,0:02:19.364
hundreds and thousands of neurons[br]are firing in the brain,

0:02:19.388,0:02:23.606
creating concurrent electrical discharges[br]in characteristic patterns

0:02:23.630,0:02:28.495
that can be measured[br]with electroencephalography, or EEG.

0:02:29.118,0:02:31.278
In fact, that's what[br]you're seeing right now.

0:02:31.956,0:02:35.920
You're seeing my brain activity[br]that was recorded in real time

0:02:35.944,0:02:38.679
with a simple device[br]that was worn on my head.

0:02:39.669,0:02:45.322
What you're seeing is my brain activity[br]when I was relaxed and curious.

0:02:46.097,0:02:47.852
To share this information with you,

0:02:47.876,0:02:50.896
I wore one of the early[br]consumer-based EEG devices

0:02:50.920,0:02:52.131
like this one,

0:02:52.155,0:02:56.143
which recorded the electrical[br]activity in my brain in real time.

0:02:56.849,0:03:00.675
It's not unlike the fitness trackers[br]that some of you may be wearing

0:03:00.699,0:03:04.285
to measure your heart rate[br]or the steps that you've taken,

0:03:04.309,0:03:05.896
or even your sleep activity.

0:03:07.154,0:03:10.978
It's hardly the most sophisticated[br]neuroimaging technique on the market.

0:03:11.597,0:03:13.975
But it's already the most portable

0:03:13.999,0:03:17.151
and the most likely to impact[br]our everyday lives.

0:03:17.915,0:03:19.418
This is extraordinary.

0:03:19.442,0:03:21.947
Through a simple, wearable device,

0:03:21.971,0:03:25.519
we can literally see[br]inside the human brain

0:03:25.543,0:03:32.019
and learn aspects of our mental landscape[br]without ever uttering a word.

0:03:32.829,0:03:36.482
While we can't reliably decode[br]complex thoughts just yet,

0:03:36.506,0:03:39.025
we can already gauge a person's mood,

0:03:39.049,0:03:41.922
and with the help[br]of artificial intelligence,

0:03:41.946,0:03:46.287
we can even decode[br]some single-digit numbers

0:03:46.311,0:03:51.193
or shapes or simple words[br]that a person is thinking

0:03:51.217,0:03:53.406
or hearing, or seeing.

0:03:54.345,0:03:57.710
Despite some inherent limitations in EEG,

0:03:57.734,0:04:02.454
I think it's safe to say[br]that with our advances in technology,

0:04:02.478,0:04:06.287
more and more of what's happening[br]in the human brain

0:04:06.311,0:04:08.621
can and will be decoded over time.

0:04:09.362,0:04:12.108
Already, using one of these devices,

0:04:12.132,0:04:15.387
an epileptic can know[br]they're going to have an epileptic seizure

0:04:15.411,0:04:16.847
before it happens.

0:04:16.871,0:04:21.474
A paraplegic can type on a computer[br]with their thoughts alone.

0:04:22.485,0:04:26.668
A US-based company has developed[br]a technology to embed these sensors

0:04:26.692,0:04:28.922
into the headrest of automobilies

0:04:28.946,0:04:31.451
so they can track driver concentration,

0:04:31.475,0:04:34.142
distraction and cognitive load[br]while driving.

0:04:34.912,0:04:38.970
Nissan, insurance companies[br]and AAA have all taken note.

0:04:39.949,0:04:44.457
You could even watch this[br]choose-your-own-adventure movie

0:04:44.481,0:04:48.721
"The Moment," which, with an EEG headset,

0:04:48.745,0:04:52.671
changes the movie[br]based on your brain-based reactions,

0:04:52.695,0:04:57.048
giving you a different ending[br]every time your attention wanes.

0:04:59.154,0:05:01.917
This may all sound great,

0:05:01.941,0:05:04.130
and as a bioethicist,

0:05:04.154,0:05:07.767
I am a huge proponent of empowering people

0:05:07.791,0:05:10.407
to take charge of their own[br]health and well-being

0:05:10.431,0:05:13.349
by giving them access[br]to information about themselves,

0:05:13.373,0:05:16.349
including this incredible[br]new brain-decoding technology.

0:05:17.878,0:05:19.045
But I worry.

0:05:19.736,0:05:24.496
I worry that we will voluntarily[br]or involuntarily give up

0:05:24.520,0:05:28.638
our last bastion of freedom,[br]our mental privacy.

0:05:29.302,0:05:32.227
That we will trade our brain activity

0:05:32.251,0:05:35.297
for rebates or discounts on insurance,

0:05:36.391,0:05:38.994
or free access[br]to social-media accounts ...

0:05:40.444,0:05:42.292
or even to keep our jobs.

0:05:42.900,0:05:44.813
In fact, in China,

0:05:46.199,0:05:52.096
the train drivers on[br]the Beijing-Shanghai high-speed rail,

0:05:52.120,0:05:54.652
the busiest of its kind in the world,

0:05:54.676,0:05:57.152
are required to wear EEG devices

0:05:57.176,0:05:59.603
to monitor their brain activity[br]while driving.

0:06:00.157,0:06:02.383
According to some news sources,

0:06:02.407,0:06:05.086
in government-run factories in China,

0:06:05.110,0:06:10.474
the workers are required to wear[br]EEG sensors to monitor their productivity

0:06:10.498,0:06:12.613
and their emotional state at work.

0:06:13.267,0:06:15.577
Workers are even sent home

0:06:15.601,0:06:19.655
if their brains show less-than-stellar[br]concentration on their jobs,

0:06:19.679,0:06:21.801
or emotional agitation.

0:06:23.189,0:06:24.934
It's not going to happen tomorrow,

0:06:24.958,0:06:28.044
but we're headed to a world[br]of brain transparency.

0:06:28.537,0:06:31.977
And I don't think people understand[br]that that could change everything.

0:06:32.474,0:06:36.149
Everything from our definitions[br]of data privacy to our laws,

0:06:36.173,0:06:37.973
to our ideas about freedom.

0:06:38.731,0:06:41.808
In fact, in my lab at Duke University,

0:06:41.832,0:06:45.007
we recently conducted a nationwide study[br]in the United States

0:06:45.031,0:06:46.990
to see if people appreciated

0:06:47.014,0:06:49.085
the sensitivity[br]of their brain information.

0:06:50.356,0:06:53.712
We asked people to rate[br]their perceived sensitivity

0:06:53.736,0:06:55.967
of 33 different kinds of information,

0:06:55.991,0:06:58.211
from their social security numbers

0:06:58.235,0:07:00.832
to the content[br]of their phone conversations,

0:07:00.856,0:07:03.049
their relationship history,

0:07:03.073,0:07:05.015
their emotions, their anxiety,

0:07:05.039,0:07:06.985
the mental images in their mind

0:07:07.009,0:07:08.547
and the thoughts in their mind.

0:07:09.481,0:07:14.710
Shockingly, people rated their social[br]security number as far more sensitive

0:07:14.734,0:07:16.937
than any other kind of information,

0:07:16.961,0:07:19.396
including their brain data.

0:07:20.380,0:07:23.596
I think this is because[br]people don't yet understand

0:07:23.620,0:07:27.683
or believe the implications[br]of this new brain-decoding technology.

0:07:28.629,0:07:31.918
After all, if we can know[br]the inner workings of the human brain,

0:07:31.942,0:07:34.648
our social security numbers[br]are the least of our worries.

0:07:34.672,0:07:35.957
(Laughter)

0:07:35.981,0:07:37.148
Think about it.

0:07:37.172,0:07:39.568
In a world of total brain transparency,

0:07:39.592,0:07:42.021
who would dare have[br]a politically dissident thought?

0:07:43.279,0:07:44.820
Or a creative one?

0:07:45.503,0:07:48.979
I worry that people will self-censor

0:07:49.003,0:07:52.305
in fear of being ostracized by society,

0:07:52.329,0:07:56.142
or that people will lose their jobs[br]because of their waning attention

0:07:56.166,0:07:58.316
or emotional instability,

0:07:58.340,0:08:01.890
or because they're contemplating[br]collective action against their employers.

0:08:02.478,0:08:05.655
That coming out[br]will no longer be an option,

0:08:05.679,0:08:10.746
because people's brains will long ago[br]have revealed their sexual orientation,

0:08:10.770,0:08:12.592
their political ideology

0:08:12.616,0:08:14.641
or their religious preferences,

0:08:14.665,0:08:17.745
well before they were ready[br]to consciously share that information

0:08:17.769,0:08:19.022
with other people.

0:08:19.565,0:08:24.477
I worry about the ability of our laws[br]to keep up with technological change.

0:08:24.986,0:08:27.306
Take the First Amendment[br]of the US Constitution,

0:08:27.330,0:08:29.288
which protects freedom of speech.

0:08:29.312,0:08:31.239
Does it also protect freedom of thought?

0:08:31.944,0:08:36.113
And if so, does that mean that we're free[br]to alter our thoughts however we want?

0:08:36.137,0:08:40.811
Or can the government or society tell us[br]what we can do with our own brains?

0:08:41.591,0:08:45.308
Can the NSA spy on our brains[br]using these new mobile devices?

0:08:46.053,0:08:50.172
Can the companies that collect[br]the brain data through their applications

0:08:50.196,0:08:52.270
sell this information to third parties?

0:08:53.174,0:08:56.396
Right now, no laws prevent them[br]from doing so.

0:08:57.203,0:08:59.228
It could be even more problematic

0:08:59.252,0:09:01.771
in countries that don't share[br]the same freedoms

0:09:01.795,0:09:03.898
enjoyed by people in the United States.

0:09:04.883,0:09:08.670
What would've happened during[br]the Iranian Green Movement

0:09:08.694,0:09:12.595
if the government had been[br]monitoring my family's brain activity,

0:09:12.619,0:09:16.626
and had believed them[br]to be sympathetic to the protesters?

0:09:18.091,0:09:21.138
Is it so far-fetched to imagine a society

0:09:21.162,0:09:24.004
in which people are arrested[br]based on their thoughts

0:09:24.028,0:09:25.195
of committing a crime,

0:09:25.219,0:09:29.531
like in the science-fiction[br]dystopian society in "Minority Report."

0:09:30.286,0:09:34.609
Already, in the United States, in Indiana,

0:09:34.633,0:09:39.570
an 18-year-old was charged[br]with attempting to intimidate his school

0:09:39.594,0:09:42.903
by posting a video of himself[br]shooting people in the hallways ...

0:09:43.881,0:09:46.888
Except the people were zombies

0:09:46.912,0:09:51.959
and the video was of him playing[br]an augmented-reality video game,

0:09:51.983,0:09:56.755
all interpreted to be a mental projection[br]of his subjective intent.

0:09:58.456,0:10:03.068
This is exactly why our brains[br]need special protection.

0:10:03.092,0:10:06.648
If our brains are just as subject[br]to data tracking and aggregation

0:10:06.672,0:10:09.204
as our financial records and transactions,

0:10:09.228,0:10:13.513
if our brains can be hacked[br]and tracked like our online activities,

0:10:13.537,0:10:15.898
our mobile phones and applications,

0:10:15.922,0:10:20.191
then we're on the brink of a dangerous[br]threat to our collective humanity.

0:10:21.406,0:10:22.715
Before you panic,

0:10:24.012,0:10:27.156
I believe that there are solutions[br]to these concerns,

0:10:27.180,0:10:30.005
but we have to start by focusing[br]on the right things.

0:10:30.580,0:10:33.501
When it comes to privacy[br]protections in general,

0:10:33.525,0:10:35.351
I think we're fighting a losing battle

0:10:35.375,0:10:38.233
by trying to restrict[br]the flow of information.

0:10:38.257,0:10:42.314
Instead, we should be focusing[br]on securing rights and remedies

0:10:42.338,0:10:44.613
against the misuse of our information.

0:10:45.291,0:10:48.576
If people had the right to decide[br]how their information was shared,

0:10:48.600,0:10:51.521
and more importantly, have legal redress

0:10:51.545,0:10:53.973
if their information[br]was misused against them,

0:10:53.997,0:10:56.783
say to discriminate against them[br]in an employment setting

0:10:56.807,0:10:59.592
or in health care or education,

0:10:59.616,0:11:02.187
this would go a long way to build trust.

0:11:02.843,0:11:04.561
In fact, in some instances,

0:11:04.585,0:11:08.109
we want to be sharing more[br]of our personal information.

0:11:08.697,0:11:11.744
Studying aggregated information[br]can tell us so much

0:11:11.768,0:11:14.515
about our health and our well-being,

0:11:14.539,0:11:17.852
but to be able to safely share[br]our information,

0:11:17.876,0:11:21.099
we need special protections[br]for mental privacy.

0:11:21.832,0:11:24.979
This is why we need[br]a right to cognitive liberty.

0:11:25.543,0:11:29.622
This right would secure for us[br]our freedom of thought and rumination,

0:11:29.646,0:11:32.186
our freedom of self-determination,

0:11:32.210,0:11:36.600
and it would insure that we have[br]the right to consent to or refuse

0:11:36.624,0:11:39.481
access and alteration[br]of our brains by others.

0:11:39.811,0:11:41.923
This right could be recognized

0:11:41.947,0:11:44.830
as part of the Universal Declaration[br]of Human Rights,

0:11:44.854,0:11:47.242
which has established mechanisms

0:11:47.266,0:11:50.122
for the enforcement[br]of these kinds of social rights.

0:11:51.872,0:11:53.942
During the Iranian Green Movement,

0:11:53.966,0:11:59.152
the protesters used the internet[br]and good old-fashioned word of mouth

0:11:59.176,0:12:01.124
to coordinate their marches.

0:12:02.238,0:12:05.007
And some of the most oppressive[br]restrictions in Iran

0:12:05.031,0:12:06.908
were lifted as a result.

0:12:08.047,0:12:12.134
But what if the Iranian government[br]had used brain surveillance

0:12:12.158,0:12:15.219
to detect and prevent the protest?

0:12:16.847,0:12:20.023
Would the world have ever heard[br]the protesters' cries?

0:12:21.732,0:12:26.853
The time has come for us to call[br]for a cognitive liberty revolution.

0:12:27.559,0:12:30.823
To make sure that we responsibly[br]advance technology

0:12:30.847,0:12:33.825
that could enable us to embrace the future

0:12:33.849,0:12:40.566
while fiercely protecting all of us[br]from any person, company or government

0:12:40.590,0:12:45.630
that attempts to unlawfully access[br]or alter our innermost lives.

0:12:46.659,0:12:47.833
Thank you.
