1
99:59:59,999 --> 99:59:59,999
Following the 2009
presidential election in Iran,

2
99:59:59,999 --> 99:59:59,999
protests erupted across the country.

3
99:59:59,999 --> 99:59:59,999
The Iranian government
violently suppressed

4
99:59:59,999 --> 99:59:59,999
what came to be known
as the Iranian Green Moevement.

5
99:59:59,999 --> 99:59:59,999
Even blocking mobile signals

6
99:59:59,999 --> 99:59:59,999
to cut off communication
between the protesters.

7
99:59:59,999 --> 99:59:59,999
My parents, who emigrated
to the United States in the late 1960s,

8
99:59:59,999 --> 99:59:59,999
spend substantial time there,

9
99:59:59,999 --> 99:59:59,999
where all of my large
extended family live.

10
99:59:59,999 --> 99:59:59,999
When I would call my family in Tehran

11
99:59:59,999 --> 99:59:59,999
during some of the most violent
crackdown of the protest,

12
99:59:59,999 --> 99:59:59,999
none of them dared discuss
with me what was happening.

13
99:59:59,999 --> 99:59:59,999
They or I knew to quickly steer
the conversation to other topics.

14
99:59:59,999 --> 99:59:59,999
All of us understood what
the consequences could be

15
99:59:59,999 --> 99:59:59,999
of a perceived dissident action.

16
99:59:59,999 --> 99:59:59,999
But I still wish I could have known
what they were thinking

17
99:59:59,999 --> 99:59:59,999
or what they were feeling.

18
99:59:59,999 --> 99:59:59,999
What if I could have?

19
99:59:59,999 --> 99:59:59,999
Or more frighteningly,

20
99:59:59,999 --> 99:59:59,999
what if the Iranian
government could have?

21
99:59:59,999 --> 99:59:59,999
Would they have arrested them
based on what their brains revealed?

22
99:59:59,999 --> 99:59:59,999
That day may be closer than you think.

23
99:59:59,999 --> 99:59:59,999
With our growing capabilities
in neuroscience, artificial intelligence

24
99:59:59,999 --> 99:59:59,999
and machine learning,

25
99:59:59,999 --> 99:59:59,999
we may soon know a lot more
of what's happening

26
99:59:59,999 --> 99:59:59,999
in the human brain.

27
99:59:59,999 --> 99:59:59,999
As a bioethicist, a lawyer,
a philosopher

28
99:59:59,999 --> 99:59:59,999
and an Iranian-American,

29
99:59:59,999 --> 99:59:59,999
I'm deeply concerned about what
this means for our freedoms

30
99:59:59,999 --> 99:59:59,999
and what kinds of protections we need.

31
99:59:59,999 --> 99:59:59,999
I believe we need
a right to cognitive liberty

32
99:59:59,999 --> 99:59:59,999
as a human right
that needs to be protected.

33
99:59:59,999 --> 99:59:59,999
If not, our freedom of thought,
access and control over our own brains

34
99:59:59,999 --> 99:59:59,999
and our mental privacy will be threatened.

35
99:59:59,999 --> 99:59:59,999
Consider this.

36
99:59:59,999 --> 99:59:59,999
The average person thinks
thousands of thoughts each day.

37
99:59:59,999 --> 99:59:59,999
As a thought takes form,

38
99:59:59,999 --> 99:59:59,999
like a math calculation or a number,

39
99:59:59,999 --> 99:59:59,999
a word,

40
99:59:59,999 --> 99:59:59,999
neurons are interacting in the brain,

41
99:59:59,999 --> 99:59:59,999
creating a miniscule electrical discharge.

42
99:59:59,999 --> 99:59:59,999
When you have a dominant
mental state like relaxation,

43
99:59:59,999 --> 99:59:59,999
hundreds and thousands of neurons
are firing in the brain,

44
99:59:59,999 --> 99:59:59,999
creating concurrent electrical discharges
in characteristic patterns

45
99:59:59,999 --> 99:59:59,999
that can measured with
electroencephalography,

46
99:59:59,999 --> 99:59:59,999
or EEG.

47
99:59:59,999 --> 99:59:59,999
In fact, that's what
you're seeing right now.

48
99:59:59,999 --> 99:59:59,999
You're seeing my brain activity
that was recorded in real time

49
99:59:59,999 --> 99:59:59,999
with a simple device
that was worn on my head.

50
99:59:59,999 --> 99:59:59,999
What you're seeing is my brain activity
when I was relaxed and curious.

51
99:59:59,999 --> 99:59:59,999
To share this information with you,

52
99:59:59,999 --> 99:59:59,999
I wore one of the early
consumer-based EEG devices

53
99:59:59,999 --> 99:59:59,999
like this one,

54
99:59:59,999 --> 99:59:59,999
which recorded the electrical
activity in my brain in real time.

55
99:59:59,999 --> 99:59:59,999
It's not unline the fitness trackers
that some of you may be wearing

56
99:59:59,999 --> 99:59:59,999
to measure your heart rate
or the steps that you've taken

57
99:59:59,999 --> 99:59:59,999
or even your sleep activity.

58
99:59:59,999 --> 99:59:59,999
It's hardly the most sophisticated
neuroimaging technique on the market.

59
99:59:59,999 --> 99:59:59,999
But it's already the most portable

60
99:59:59,999 --> 99:59:59,999
and the most likely to impact
our everyday lives.

61
99:59:59,999 --> 99:59:59,999
This is extraordinary.

62
99:59:59,999 --> 99:59:59,999
Through a simple, wearable device,

63
99:59:59,999 --> 99:59:59,999
we can literally see
inside the human brain

64
99:59:59,999 --> 99:59:59,999
and learn aspects of our mental landscape
without ever uttering a word.

65
99:59:59,999 --> 99:59:59,999
While we can't reliably decode
complex thoughts just yet,

66
99:59:59,999 --> 99:59:59,999
we can already gage a person's mood,

67
99:59:59,999 --> 99:59:59,999
and with the help
of artificial intelligence,

68
99:59:59,999 --> 99:59:59,999
we can even decode
some single-digit numbers

69
99:59:59,999 --> 99:59:59,999
or shapes or simple words
that a person is thinking or hearing

70
99:59:59,999 --> 99:59:59,999
or seeing.

71
99:59:59,999 --> 99:59:59,999
Despite some inherent limitations in EEG,

72
99:59:59,999 --> 99:59:59,999
I think it's safe to say that with
our advances in technology,

73
99:59:59,999 --> 99:59:59,999
more and more of what's happening
in the human brain

74
99:59:59,999 --> 99:59:59,999
can and will be decoded over time.

75
99:59:59,999 --> 99:59:59,999
Already, using one of these devices,
an epileptic can know

76
99:59:59,999 --> 99:59:59,999
they're going to have an epileptic
seizure before it happens.

77
99:59:59,999 --> 99:59:59,999
A paraplegic can type on a computer
with their thoughts alone.

78
99:59:59,999 --> 99:59:59,999
A US-based company has developed
a technology to embed these censors

79
99:59:59,999 --> 99:59:59,999
into the headrest of automobilies

80
99:59:59,999 --> 99:59:59,999
so they can track driver concentration,

81
99:59:59,999 --> 99:59:59,999
distraction

82
99:59:59,999 --> 99:59:59,999
and cognitive load while driving.

83
99:59:59,999 --> 99:59:59,999
Nissan, insurance companies
and AAA have all taken note.

84
99:59:59,999 --> 99:59:59,999
You could even watch this
choose-your-own adventure movie,

85
99:59:59,999 --> 99:59:59,999
"The Moment,"

86
99:59:59,999 --> 99:59:59,999
which, with an EEG headset,

87
99:59:59,999 --> 99:59:59,999
changes the movie based
on your brain-based reactions,

88
99:59:59,999 --> 99:59:59,999
giving you a different ending
every time your attention wanes.

89
99:59:59,999 --> 99:59:59,999
This may all sound great,

90
99:59:59,999 --> 99:59:59,999
and as a bioethicist,
I am a huge proponent

91
99:59:59,999 --> 99:59:59,999
of empowering people to take charge
of their own health and wellbeing

92
99:59:59,999 --> 99:59:59,999
by giving them access
to information about themselves,

93
99:59:59,999 --> 99:59:59,999
including this incredible, new
brain decoding technology.

94
99:59:59,999 --> 99:59:59,999
But I worry.

95
99:59:59,999 --> 99:59:59,999
I worry that we will voluntarily
or involuntarily give up

96
99:59:59,999 --> 99:59:59,999
our last bastion of freedom ...

97
99:59:59,999 --> 99:59:59,999
our mental privacy.

98
99:59:59,999 --> 99:59:59,999
That we will trade our brain activity
for rebates or discounts on insurance,

99
99:59:59,999 --> 99:59:59,999
or free access to social
media accounts ...

100
99:59:59,999 --> 99:59:59,999
or even to keep our jobs.

101
99:59:59,999 --> 99:59:59,999
In fact, in China, the train drivers 
on the Beijing-Shangia high-speed rail,

102
99:59:59,999 --> 99:59:59,999
the busiest of its kind in the world,

103
99:59:59,999 --> 99:59:59,999
are required to wear EEG devices
to monitor their brain activity

104
99:59:59,999 --> 99:59:59,999
while driving.

105
99:59:59,999 --> 99:59:59,999
According to some news sources,

106
99:59:59,999 --> 99:59:59,999
in government-run factories in China,

107
99:59:59,999 --> 99:59:59,999
the workers are required to wear
EEG censors to monitor their productivity

108
99:59:59,999 --> 99:59:59,999
and their emotional state at work.

109
99:59:59,999 --> 99:59:59,999
Workers are even sent home if their brain
shows less than stellar concentration

110
99:59:59,999 --> 99:59:59,999
on their jobs,

111
99:59:59,999 --> 99:59:59,999
or emotional agitation.

112
99:59:59,999 --> 99:59:59,999
It's not going to happen tomorrow,

113
99:59:59,999 --> 99:59:59,999
but we're headed to a world
of brain transparency.

114
99:59:59,999 --> 99:59:59,999
And I don't think people understand
that that could change everything.

115
99:59:59,999 --> 99:59:59,999
Everything from our definitions
of data privacy to our laws,

116
99:59:59,999 --> 99:59:59,999
to our ideas about freedom.

117
99:59:59,999 --> 99:59:59,999
In fact, in my lab at Duke University,

118
99:59:59,999 --> 99:59:59,999
we recently conducted a nationwide study

119
99:59:59,999 --> 99:59:59,999
in the United States

120
99:59:59,999 --> 99:59:59,999
to see if people appreciated.

121
99:59:59,999 --> 99:59:59,999
the sensitivity of
their brain information.

122
99:59:59,999 --> 99:59:59,999
We asked people to rate
their perceived sensitivity

123
99:59:59,999 --> 99:59:59,999
of 33 different kinds of information,

124
99:59:59,999 --> 99:59:59,999
from their social security numbers

125
99:59:59,999 --> 99:59:59,999
to the content of their
phone conversations,

126
99:59:59,999 --> 99:59:59,999
their relationship history,

127
99:59:59,999 --> 99:59:59,999
their emotions, their anxiety,
the mental images in their mind

128
99:59:59,999 --> 99:59:59,999
and the thoughts in their mind.

129
99:59:59,999 --> 99:59:59,999
Shockingly, people rated their social
security number as far more sensitive

130
99:59:59,999 --> 99:59:59,999
than any other kind of information,

131
99:59:59,999 --> 99:59:59,999
including their brain data.

132
99:59:59,999 --> 99:59:59,999
I think this is because
people don't yet understand

133
99:59:59,999 --> 99:59:59,999
or believe the implications
of this new brain decoding technology.

134
99:59:59,999 --> 99:59:59,999
After all, if we can know the inner
workings of the human brain,

135
99:59:59,999 --> 99:59:59,999
our social security numbers
are the least of our worries.

136
99:59:59,999 --> 99:59:59,999
(Laughter)

137
99:59:59,999 --> 99:59:59,999
Think about it.

138
99:59:59,999 --> 99:59:59,999
In a world of total brain transparency,

139
99:59:59,999 --> 99:59:59,999
who would dare have
a politically dissident thought?

140
99:59:59,999 --> 99:59:59,999
Or a creative one?

141
99:59:59,999 --> 99:59:59,999
I worry that people will self-censor
in fear of being ostracized by society,

142
99:59:59,999 --> 99:59:59,999
or that people will lose their jobs
because of their waning attention

143
99:59:59,999 --> 99:59:59,999
or emotional instability,

144
99:59:59,999 --> 99:59:59,999
or because they're contemplating
collective action against their employers.

145
99:59:59,999 --> 99:59:59,999
That coming out
will no longer be an option

146
99:59:59,999 --> 99:59:59,999
because people's brains will long ago
have revealed their sexual orientation,

147
99:59:59,999 --> 99:59:59,999
their political ideaology,

148
99:59:59,999 --> 99:59:59,999
or their religious preferences,

149
99:59:59,999 --> 99:59:59,999
well before they were ready
to conciously share that information

150
99:59:59,999 --> 99:59:59,999
with other people.

151
99:59:59,999 --> 99:59:59,999
I worry about the ability of our laws
to keep up with technological change.

152
99:59:59,999 --> 99:59:59,999
Take the first amendment
of the US Constitution,

153
99:59:59,999 --> 99:59:59,999
which protects freedom of speech.

154
99:59:59,999 --> 99:59:59,999
Does it also protect freedom of thought?

155
99:59:59,999 --> 99:59:59,999
And if so, does that mean that we're free
to alter our thoughts however we want?

156
99:59:59,999 --> 99:59:59,999
Or can the government or society tell us
what we can do with our own brains?

157
99:59:59,999 --> 99:59:59,999
Can the NSA spy on our brains
using these new mobile devices?

158
99:59:59,999 --> 99:59:59,999
Can the companies that collect
the brain data through their applications

159
99:59:59,999 --> 99:59:59,999
sell this information to third parties?

160
99:59:59,999 --> 99:59:59,999
Right now, no laws prevent
them from doing so.

161
99:59:59,999 --> 99:59:59,999
It could be even more problematic

162
99:59:59,999 --> 99:59:59,999
in countries that don't share
the same freedoms

163
99:59:59,999 --> 99:59:59,999
enjoyed by people in the United States.

164
99:59:59,999 --> 99:59:59,999
What would've happened during
the Iranian Green Movement

165
99:59:59,999 --> 99:59:59,999
if the government had been
monitoring my family's brain activity?

166
99:59:59,999 --> 99:59:59,999
And had believed them to be
sympathetic to the protesters?

167
99:59:59,999 --> 99:59:59,999
Is it so far-fetched to imagine a society


168
99:59:59,999 --> 99:59:59,999
in which people are arrested
based on their thoughts

169
99:59:59,999 --> 99:59:59,999
of commiting a crime?

170
99:59:59,999 --> 99:59:59,999
LIke in the science-fiction, dystopian
society in "Minority Report."

171
99:59:59,999 --> 99:59:59,999
Already, in the United States, in Indiana,

172
99:59:59,999 --> 99:59:59,999
an 18-year-old was charged
with attempting to intimidate his school

173
99:59:59,999 --> 99:59:59,999
by posting a video of himself
shooting people in the hallways,

174
99:59:59,999 --> 99:59:59,999
except the people were zombies

175
99:59:59,999 --> 99:59:59,999
and the video was of him playing
and augmented-reality video game.

176
99:59:59,999 --> 99:59:59,999
All interpreted to be a mental projection
of his subjective intent.

177
99:59:59,999 --> 99:59:59,999
This is exactly why our brains
need special protection.

178
99:59:59,999 --> 99:59:59,999
If our brains are just as subject
to data tracking and aggragation

179
99:59:59,999 --> 99:59:59,999
as our financial records and transactions,

180
99:59:59,999 --> 99:59:59,999
if you brains can be hacked
and tracked like our online activities,

181
99:59:59,999 --> 99:59:59,999
our mobile phones and applications,

182
99:59:59,999 --> 99:59:59,999
then we're on the brink of a dangerous
threat to our collective humanity.

183
99:59:59,999 --> 99:59:59,999
Before you panic,

184
99:59:59,999 --> 99:59:59,999
I believe that there are solutions
to these concerns,

185
99:59:59,999 --> 99:59:59,999
but we have to start by focusing
on the right things.

186
99:59:59,999 --> 99:59:59,999
When it comes to privacy
protections in general,

187
99:59:59,999 --> 99:59:59,999
I think we're fighting a losing battle

188
99:59:59,999 --> 99:59:59,999
by trying to restrict
the flow of information.

189
99:59:59,999 --> 99:59:59,999
Instead, we should be focusing
on securing rights and remedies

190
99:59:59,999 --> 99:59:59,999
against the misuse of our information.

191
99:59:59,999 --> 99:59:59,999
If people had the right to decide
how their information was shared,

192
99:59:59,999 --> 99:59:59,999
and more importantly,

193
99:59:59,999 --> 99:59:59,999
have legal redress,

194
99:59:59,999 --> 99:59:59,999
if their information
was misused against them,

195
99:59:59,999 --> 99:59:59,999
say to discriminate against them
in an employment setting

196
99:59:59,999 --> 99:59:59,999
or in health care and education,

197
99:59:59,999 --> 99:59:59,999
this would go a long way to build trust.

198
99:59:59,999 --> 99:59:59,999
In fact, in some instances,

199
99:59:59,999 --> 99:59:59,999
we want to be sharing more
of our personal information.

200
99:59:59,999 --> 99:59:59,999
Studying aggregated information
can tell us so much

201
99:59:59,999 --> 99:59:59,999
about our health and our wellbeing,

202
99:59:59,999 --> 99:59:59,999
but to be able to safely
share our information,

203
99:59:59,999 --> 99:59:59,999
we need special protections
for mental privacy.

204
99:59:59,999 --> 99:59:59,999
This is why we need a right
to cognitive liberty.

205
99:59:59,999 --> 99:59:59,999
This right would secure for us
our freedom of thought and rumination,

206
99:59:59,999 --> 99:59:59,999
our freedom of self-determination

207
99:59:59,999 --> 99:59:59,999
and it would insure that we have
the right to consent to or refuse

208
99:59:59,999 --> 99:59:59,999
access and alteration
of our brains by others.

209
99:59:59,999 --> 99:59:59,999
This right could be recognized

210
99:59:59,999 --> 99:59:59,999
as part of the universal
declaration of human rights,

211
99:59:59,999 --> 99:59:59,999
which has established mechanisms

212
99:59:59,999 --> 99:59:59,999
for the enforcement of these
kinds of social rights.

213
99:59:59,999 --> 99:59:59,999
During the Iranian Green Movement,

214
99:59:59,999 --> 99:59:59,999
the protesters used the internet
and good old-fashioned word-of-mouth

215
99:59:59,999 --> 99:59:59,999
to coordinate their marches.

216
99:59:59,999 --> 99:59:59,999
And some of the most oppressive
restrictions in Iran

217
99:59:59,999 --> 99:59:59,999
were lifted as a result.

218
99:59:59,999 --> 99:59:59,999
But what if the Iranian government
had used brain surveillance

219
99:59:59,999 --> 99:59:59,999
to detect and prevent the protest?

220
99:59:59,999 --> 99:59:59,999
Would the world have ever heard
the protester's cries?

221
99:59:59,999 --> 99:59:59,999
The time has come for us to call
for cognitive liberty revolution.

222
99:59:59,999 --> 99:59:59,999
To make sure that we responsibly
advance technology

223
99:59:59,999 --> 99:59:59,999
that can enable us to embrace the future

224
99:59:59,999 --> 99:59:59,999
while fiercely protecting all of us

225
99:59:59,999 --> 99:59:59,999
from any person, company or government
that attempts to unlawfully access

226
99:59:59,999 --> 99:59:59,999
or alter our innermost lives.

227
99:59:59,999 --> 99:59:59,999
Thank you.

228
99:59:59,999 --> 99:59:59,999
(Applause)
