1
00:00:07,497 --> 00:00:09,138
Inspired by the last talker

2
00:00:09,138 --> 00:00:12,983
I'm going to have a little song
about Internet porn.

3
00:00:12,983 --> 00:00:15,515
No, just kidding.

4
00:00:15,515 --> 00:00:19,620
The widespread use of Internet porn
is one of the fastest moving

5
00:00:19,620 --> 00:00:23,749
most global experiments ever
unconsciously conducted.

6
00:00:23,749 --> 00:00:26,734
Nearly every young guy
with an Internet access

7
00:00:26,734 --> 00:00:29,446
becomes an eager test subject.

8
00:00:30,072 --> 00:00:32,459
Canadian researcher
Simon Lajeunesse found

9
00:00:32,459 --> 00:00:36,327
that most boys
seek pornography by age 10.

10
00:00:36,327 --> 00:00:41,338
Driven by a brain that is suddenly
fascinated by sex.

11
00:00:41,338 --> 00:00:45,134
Now, users perceive Internet porn
as far more compelling

12
00:00:45,134 --> 00:00:46,684
than porn of the past.

13
00:00:46,684 --> 00:00:48,048
Why is that?

14
00:00:48,048 --> 00:00:50,680
Unending novelty.

15
00:00:50,680 --> 00:00:52,379
In this Australian experiment,

16
00:00:52,379 --> 00:00:57,882
it's not mere nudity but novelty
that gets arousals skyrocketing.

17
00:00:57,882 --> 00:01:01,567
Subjects watch 22 porn displays.
See that spike?

18
00:01:01,567 --> 00:01:04,642
That's where the researchers
switch to porn

19
00:01:04,642 --> 00:01:06,782
the guys hadn't seen before.

20
00:01:06,782 --> 00:01:11,705
What happened?
Their erections and their brains fired up.

21
00:01:11,705 --> 00:01:13,499
Why all the excitement?

22
00:01:13,499 --> 00:01:17,421
Mother nature likes to keep
a male fertilizing willing females

23
00:01:17,421 --> 00:01:19,942
as long as any new ones are around.

24
00:01:19,942 --> 00:01:22,393
In that top line the ram,

25
00:01:22,393 --> 00:01:28,283
he needs more and more time
to make with the same old ewe.

26
00:01:28,283 --> 00:01:37,030
But if you keep switching females -
the bottom line - well she's not the same.

27
00:01:37,030 --> 00:01:39,997
He can get the job done in 2 minutes flat

28
00:01:39,997 --> 00:01:43,617
and keep going
until he's utterly exhausted.

29
00:01:43,617 --> 00:01:46,445
This is known as the Coolidge effect.

30
00:01:46,445 --> 00:01:51,324
Without the Coolidge effect
there would be no Internet porn.

31
00:01:51,324 --> 00:01:54,886
This old mammalian program,
the Coolidge effect, perceives

32
00:01:54,886 --> 00:02:02,159
each novel female on a guy's screen
as a genetic opportunity.

33
00:02:02,159 --> 00:02:06,052
To keep a guy fertilizing
the screen his brain releases

34
00:02:06,052 --> 00:02:11,835
the "go get it" neurochemical dopamine
for each novel mate or image.

35
00:02:11,835 --> 00:02:13,800
Eventually the ram will tire

36
00:02:13,800 --> 00:02:15,787
but as long as the guy can keep clicking

37
00:02:15,787 --> 00:02:18,742
he can keep going
and so will his dopamine.

38
00:02:18,742 --> 00:02:22,826
With internet porn a guy can see
more hot babes in 10 minutes

39
00:02:22,826 --> 00:02:27,459
than his ancestors could see
in several lifetimes.

40
00:02:27,459 --> 00:02:31,342
The problem is he has
a hunter-gather brain.

41
00:02:31,342 --> 00:02:37,523
A heavy user brain rewires
itself to this genetic bonanza

42
00:02:37,523 --> 00:02:44,271
so it carefully becomes associated
with this porn harem.

43
00:02:44,287 --> 00:02:48,698
Such behaviours that are associated
with this are being alone,

44
00:02:48,698 --> 00:02:52,250
voyeurism, clicking,
searching, multiple tabs

45
00:02:52,250 --> 00:02:57,295
fast-forwarding, constant novelty,
shock and surprise.

46
00:02:57,295 --> 00:02:59,095
As one young guy once asked:

47
00:02:59,095 --> 00:03:04,415
Are we the first generation
to masturbate left handed?

48
00:03:04,415 --> 00:03:09,480
Now, real sex, in contrast,
is courtship, touching,

49
00:03:09,480 --> 00:03:13,669
being touched, smells, pheromones,
emotional connection,

50
00:03:13,669 --> 00:03:17,031
interaction with a real person.

51
00:03:17,031 --> 00:03:23,435
Now, what happens when our guy
finally gets with a real mate.

52
00:03:23,435 --> 00:03:26,614
Well, researchers don't know
much about the effects

53
00:03:26,614 --> 00:03:29,644
of Internet porn for several reasons.

54
00:03:29,644 --> 00:03:34,774
In 2009, when Lajeunesse
tried to study porn's impact

55
00:03:34,774 --> 00:03:39,717
he couldn't find any college age males
who weren't using it.

56
00:03:39,717 --> 00:03:45,659
So the first serious dilemma
is that studies have no control groups.

57
00:03:45,659 --> 00:03:48,973
Now, this creates a huge blind spot.

58
00:03:48,973 --> 00:03:52,852
Imagine if all guys
started smoking at age 10

59
00:03:52,852 --> 00:03:55,122
and there were no groups that didn't.

60
00:03:55,122 --> 00:03:59,890
We would think that lung cancer
is normal for all guys.

61
00:03:59,890 --> 00:04:05,898
Undaunted by his lack of non-users
Lajeunesse asked 20 male students:

62
00:04:05,898 --> 00:04:11,185
Is Internet porn affecting you
or your attitude towards women?

63
00:04:11,185 --> 00:04:14,353
They answered,
"No, I don't think so."

64
00:04:14,353 --> 00:04:16,835
But they've been using it
for about a decade then

65
00:04:16,835 --> 00:04:19,185
pretty much non-stop.

66
00:04:19,185 --> 00:04:24,361
This is like asking a fish
what it thinks about water?

67
00:04:24,361 --> 00:04:26,892
Which bring us to a second problem.

68
00:04:26,892 --> 00:04:31,331
Researchers haven't asked porn users
about the symptoms

69
00:04:31,331 --> 00:04:35,539
Zimbardo described in
"The Demise of Guys."

70
00:04:35,539 --> 00:04:38,250
Arousal addiction symptoms
are easily mistaken

71
00:04:38,250 --> 00:04:44,370
for such things as ADHD,
social anxiety, depression,

72
00:04:44,370 --> 00:04:47,906
concentration problems,
performance anxiety,

73
00:04:47,906 --> 00:04:50,326
OCD and a host of others.

74
00:04:50,326 --> 00:04:55,745
Now, healthcare providers often assume
that these conditions are primary

75
00:04:55,745 --> 00:05:01,545
perhaps the cause of addiction but
never really the result of an addiction.

76
00:05:01,545 --> 00:05:05,943
As a consequence they often
medicate these guys

77
00:05:05,943 --> 00:05:11,292
without really inquiring about
if they have an Internet addiction.

78
00:05:11,292 --> 00:05:13,958
Guys never realise
that they could overcome these

79
00:05:13,958 --> 00:05:18,059
symptoms simply
by changing their behaviour.

80
00:05:18,059 --> 00:05:21,511
Now, the third problem
is it's hard to believe that

81
00:05:21,511 --> 00:05:26,608
sexual activity can cause addiction
because sex is healthy.

82
00:05:26,608 --> 00:05:28,627
But Internet porn is not sex.

83
00:05:28,627 --> 00:05:32,807
Internet porn
is as different from real sex

84
00:05:32,807 --> 00:05:36,867
as todays video games are from checkers.

85
00:05:36,867 --> 00:05:39,828
Watching the screen
full of naked body parts

86
00:05:39,828 --> 00:05:45,212
won't automatically protect one
from arousal addiction.

87
00:05:45,212 --> 00:05:48,579
In this Dutch study - here's the title -

88
00:05:48,579 --> 00:05:53,435
they found that in fact of all activities
on the Internet

89
00:05:53,435 --> 00:05:57,045
porn has the most potential
to become addictive.

90
00:05:57,045 --> 00:05:58,216
Here's why.

91
00:05:58,216 --> 00:06:00,618
This ancient programme,
the reward circuit,

92
00:06:00,618 --> 00:06:04,773
evolved to drive us towards
natural rewards

93
00:06:04,773 --> 00:06:09,195
such as sex, bonding and food.

94
00:06:09,195 --> 00:06:13,482
As a consequence extreme versions
of natural rewards

95
00:06:13,482 --> 00:06:17,747
have a unique ability to capture us.

96
00:06:17,747 --> 00:06:22,422
For example: high-calorie foods
or hot novel babes

97
00:06:22,422 --> 00:06:24,892
give us extra dopamine.

98
00:06:24,892 --> 00:06:30,753
Too much dopamine though can override
our natural satiation mechanisms.

99
00:06:30,753 --> 00:06:34,180
For example: give rats unlimited access

100
00:06:34,180 --> 00:06:39,228
to junk food and almost all of them
will binge to obesity.

101
00:06:39,228 --> 00:06:42,665
This is also why 4 out of 5 Americans
are overweight

102
00:06:42,665 --> 00:06:45,201
and about half of those are obese.

103
00:06:45,201 --> 00:06:47,006
That is addicted to food.

104
00:06:47,006 --> 00:06:51,366
Now, in contrast to natural rewards,
drugs such as

105
00:06:51,366 --> 00:06:55,732
cocaine or alcohol only hook
about 10% of users

106
00:06:55,732 --> 00:06:58,484
whether they are rats or humans.

107
00:06:59,521 --> 00:07:06,933
This binge mechanism for food or sex
was once an evolutionary advantage.

108
00:07:06,933 --> 00:07:10,381
In essence, it is getting it while
the getting is good.

109
00:07:10,381 --> 00:07:14,152
Now, you can think of wolves packing
away 20 pound of meat per kill

110
00:07:14,152 --> 00:07:18,433
or it's mating season
and you're the alpha male.

111
00:07:18,433 --> 00:07:21,872
What if mating season never ends?

112
00:07:21,872 --> 00:07:26,071
All those hits of dopamine can tell
your brain to do two things.

113
00:07:26,071 --> 00:07:30,011
First they say, "Man, you've hit
the evolutionary jackpot."

114
00:07:30,011 --> 00:07:35,745
Second, they kick in a molecular switch
called Delta-FosB.

115
00:07:35,745 --> 00:07:39,738
I know it is a fancy word,
but dopamine kicks in Delta-FosB

116
00:07:39,738 --> 00:07:44,657
and that starts to accumulate
in the brain's reward circuit.

117
00:07:44,657 --> 00:07:48,974
Now, with excess chronic consumption
of drugs or natural rewards,

118
00:07:48,974 --> 00:07:52,969
this build up a Delta-FosB
starts to alter the brain

119
00:07:52,969 --> 00:07:57,947
and promotes the cycle
of binging and craving.

120
00:07:57,947 --> 00:08:01,217
If the binging continues
the Delta-FosB builds up

121
00:08:01,217 --> 00:08:04,611
and it can lead to brain changes
seen in all addicts.

122
00:08:04,611 --> 00:08:08,230
So the dominos are excess consumption

123
00:08:08,230 --> 00:08:12,554
excess dopamine,
Delta-FosB, brain changes.

124
00:08:12,554 --> 00:08:16,480
One of the first changes
is a numbed pleasure response.

125
00:08:16,480 --> 00:08:23,931
It kicks in, and so everyday pleasures
really don't satisfy a porn addict.

126
00:08:23,931 --> 00:08:26,741
At the same time other
physical changes in the brain

127
00:08:26,741 --> 00:08:29,647
make the brain hyper-reactive to porn.

128
00:08:29,647 --> 00:08:33,159
Everything else in the porn user's life
is sort of boring,

129
00:08:33,172 --> 00:08:35,529
but porn is super exciting.

130
00:08:35,529 --> 00:08:40,111
Finally his willpower erodes
as his frontal cortex changes.

131
00:08:40,111 --> 00:08:41,988
I can't emphasize this enough.

132
00:08:41,988 --> 00:08:45,462
All addictions share
these same brain changes

133
00:08:45,462 --> 00:08:52,032
and the same molecular switch
that kicks them in - Delta-FosB.

134
00:08:52,032 --> 00:08:55,020
Now scientists have used
brain scans to measure

135
00:08:55,020 --> 00:08:57,336
these changes in drug addicts.

136
00:08:57,336 --> 00:09:02,055
Up-here these scans show a reduced
pleasure response in drug addicts.

137
00:09:02,055 --> 00:09:06,590
These and several other changes
have also been seen in gambling addicts,

138
00:09:06,590 --> 00:09:10,622
food addicts, very recently
in video game addicts

139
00:09:11,322 --> 00:09:13,622
and now in internet addicts.

140
00:09:13,622 --> 00:09:16,767
I apologize for filling up the slide
with brain studies.

141
00:09:16,767 --> 00:09:18,947
Just notice the dates.

142
00:09:18,947 --> 00:09:22,387
But I want you to know that they exist.

143
00:09:22,660 --> 00:09:27,175
So far all brain research points
only in one direction.

144
00:09:27,175 --> 00:09:32,780
Constant novelty at the click
can cause addiction.

145
00:09:32,780 --> 00:09:36,506
We know this because
when scientist examined

146
00:09:36,506 --> 00:09:38,425
former Internet addicts they found

147
00:09:38,425 --> 00:09:42,367
that these brain changes
were reversing themselves.

148
00:09:42,367 --> 00:09:46,988
Unfortunately, none of these studies
isolate porn users,

149
00:09:46,988 --> 00:09:49,124
but they do include them.

150
00:09:49,124 --> 00:09:51,413
Here's the game changer.

151
00:09:51,413 --> 00:09:55,622
At last we have a group of guys
who are no longer using Internet porn.

152
00:09:55,622 --> 00:10:01,592
That's right! Heavy users are voluntarily
giving it up by the thousands.

153
00:10:01,592 --> 00:10:07,350
These guys are the missing control group
in the great porn experiment.

154
00:10:07,350 --> 00:10:12,285
They're showing experts what changing
one single variable can do.

155
00:10:12,285 --> 00:10:16,442
I call it "The Resurrection of Guys"
as opposed to "the Demise of Guys."

156
00:10:16,442 --> 00:10:18,722
Now, before I continue
probably you wanna know

157
00:10:18,722 --> 00:10:23,149
why any porn loving guy
in his right mind would give it up.

158
00:10:23,149 --> 00:10:27,820
Two words: erectile dysfunction.

159
00:10:27,820 --> 00:10:31,737
Internet porn is killing
young men's sexual performance.

160
00:10:31,737 --> 00:10:35,519
Now, Zimbardo said young guys
are flaming out with women,

161
00:10:35,519 --> 00:10:39,126
this survey by Italian neurologists
confirms

162
00:10:39,126 --> 00:10:43,262
what we have witnessed
over the last few years.

163
00:10:45,447 --> 00:10:49,242
Sexual enhancement drugs
often stop working for these guys,

164
00:10:49,242 --> 00:10:50,312
if they ever did,

165
00:10:50,312 --> 00:10:54,103
because the problem isn't 
below the belt where viagra works.

166
00:10:54,103 --> 00:10:56,669
Nor is their problem really psychological.

167
00:10:56,669 --> 00:10:59,489
It's due to physical changes
in the brain.

168
00:10:59,489 --> 00:11:01,780
Those addiction related changes.

169
00:11:01,780 --> 00:11:06,215
Their numb brains are sending weaker
and weaker signals to their bananas.

170
00:11:06,215 --> 00:11:08,255
(Laughter)

171
00:11:08,255 --> 00:11:13,433
As doctor Foresta says, "It starts
with lower reactions to porn sites.

172
00:11:13,433 --> 00:11:16,391
Then there is a general drop in libido,

173
00:11:16,391 --> 00:11:20,815
and in the end it becomes impossible
to get an erection.

174
00:11:20,815 --> 00:11:23,309
There are 3 take-aways from this.

175
00:11:23,309 --> 00:11:28,477
First, Foresta is describing
a classic addiction process -

176
00:11:28,477 --> 00:11:31,276
gradual desensitization.

177
00:11:31,276 --> 00:11:36,137
Second, Internet porn is qualitatively
different from Playboy.

178
00:11:36,137 --> 00:11:40,769
Widespread youthful ED
has never been seen before.

179
00:11:40,769 --> 00:11:48,111
And finally ED is often the only symptom
that gets these guys' attention.

180
00:11:48,111 --> 00:11:52,771
The question is what less obvious symptoms
are they missing?

181
00:11:52,771 --> 00:11:56,793
Most don't figure
that out until after they quit.

182
00:11:56,793 --> 00:12:00,600
Here's a guy in his late 20s.

183
00:12:00,600 --> 00:12:04,095
"I've been to psychologists
and psychiatrists for the last 8 years...

184
00:12:04,095 --> 00:12:08,086
have been diagnosed with depression,
severe social anxiety,

185
00:12:08,086 --> 00:12:10,645
severe memory impairment and a few others.

186
00:12:10,645 --> 00:12:14,307
Have tried Fexer, Ritalin, Xanax, Paxil

187
00:12:14,307 --> 00:12:17,764
dropped out at two different colleges,
been fired twice,

188
00:12:17,764 --> 00:12:20,849
used pot to calm my social anxiety.

189
00:12:20,849 --> 00:12:22,922
I've been approached by quite a few women

190
00:12:22,922 --> 00:12:25,084
I guess due to my looks and status

191
00:12:25,084 --> 00:12:28,480
but they quickly flew away
due to my incredible weirdness.

192
00:12:28,480 --> 00:12:32,105
I've been a hardcore porn addict
since age 14.

193
00:12:32,105 --> 00:12:34,547
For the last 2 years
I've been experimenting

194
00:12:34,547 --> 00:12:38,092
and finally realised
that porn was an issue.

195
00:12:38,092 --> 00:12:41,434
I stopped it completely 2 months ago.

196
00:12:41,434 --> 00:12:45,152
It has been very difficult
but so far incredibly worth it.

197
00:12:45,152 --> 00:12:48,973
I've since quit my remaining medication.

198
00:12:48,973 --> 00:12:51,541
My anxiety is nonexistent.

199
00:12:51,541 --> 00:12:55,062
My memory and focus are sharper
than they've ever been.

200
00:12:55,062 --> 00:12:59,215
I feel like a huge "chick magnet"
and my ED is gone too.

201
00:12:59,215 --> 00:13:05,447
I seriously think I had a rebirth,
a second chance at life."

202
00:13:05,447 --> 00:13:10,151
This is why pockets of guys are peering
all over the web - body building sites,

203
00:13:10,151 --> 00:13:14,591
sports sites, pickup artists sites -
wherever men congregate.

204
00:13:14,591 --> 00:13:18,397
In essence, they are seeking
a neurochemical rebirth.

205
00:13:18,397 --> 00:13:22,365
Here's a group on reddit.com
who call themselves "Fapstronauts."

206
00:13:22,365 --> 00:13:25,666
Fapping is slang for solo sex,

207
00:13:25,666 --> 00:13:29,494
but what they really mean
is giving up porn.

208
00:13:29,494 --> 00:13:35,986
They've added about 2,000 members
since I captured this picture a month ago.

209
00:13:35,986 --> 00:13:41,192
This movement to unhook from porn
is growing rapidly.

210
00:13:41,192 --> 00:13:46,670
In fact, groups are springing up
all across the web and in Europe too.

211
00:13:46,670 --> 00:13:51,356
But there is a bizarre fly
in the ointment.

212
00:13:51,356 --> 00:13:54,603
Guys in the early 20s aren't regaining

213
00:13:54,603 --> 00:13:58,264
their erectile health
as quickly as older guys.

214
00:13:58,698 --> 00:14:06,134
How can a 50-year-old get his mojo back
quicker then a 20-something?

215
00:14:06,134 --> 00:14:10,453
The answer, even though older guys
have been using porn a whole lot longer

216
00:14:10,453 --> 00:14:14,538
they didn't start
on today's Internet porn.

217
00:14:14,538 --> 00:14:17,057
Now, we know
this is a key variable because

218
00:14:17,057 --> 00:14:20,562
the older guys didn't start
having sexual problems

219
00:14:20,562 --> 00:14:27,664
until after they got
high-speed Internet. (Laughter)

220
00:14:27,664 --> 00:14:31,781
Now, today's young teens
start on high-speed Internet

221
00:14:31,781 --> 00:14:34,650
when their brains are at their peak

222
00:14:34,650 --> 00:14:37,650
of dopamine production
and neuroplasticity.

223
00:14:37,650 --> 00:14:40,926
This is also when they are
the most vulnerable to addiction,

224
00:14:40,926 --> 00:14:43,237
but there is another risk.

225
00:14:43,926 --> 00:14:47,096
By adulthood teens strengthen
heavily used circuits

226
00:14:47,096 --> 00:14:49,425
and prune back unused ones.

227
00:14:49,425 --> 00:14:56,470
So, by age 22 or so a guy's sexual taste
can be like deep ruts in his brain.

228
00:14:56,470 --> 00:15:01,936
This can cause panic
if a guy has escalated to extreme porn

229
00:15:01,936 --> 00:15:06,096
or porn that no longer matches
his sexual orientation.

230
00:15:06,096 --> 00:15:08,784
Fortunately brains are plastic

231
00:15:08,784 --> 00:15:14,830
so his taste can revert
once he quits porn.

232
00:15:14,830 --> 00:15:17,443
As a guy returns to normal sensitivity

233
00:15:17,443 --> 00:15:21,749
his brain looks around for the rewards
it evolved to see

234
00:15:21,749 --> 00:15:25,358
such as friendly interaction
and of course real mates.

235
00:15:25,358 --> 00:15:29,498
Here's one more example
of what we hear everyday,

236
00:15:29,498 --> 00:15:33,589
"I feel like the next Sir Isaac Newton
or Leonardo da Vinci.

237
00:15:33,589 --> 00:15:35,596
Since I quit a month ago, I've literally:

238
00:15:35,596 --> 00:15:40,299
started a business, taken up piano,
been studying French every day,

239
00:15:40,299 --> 00:15:44,366
been programming, drawing,
writing, started managing my finances

240
00:15:44,366 --> 00:15:48,721
and I have more awesome ideas
than I know what to do with.

241
00:15:48,721 --> 00:15:51,053
My confidence is sky-high.

242
00:15:51,053 --> 00:15:54,346
I already feel like
I can talk to any girl!

243
00:15:54,346 --> 00:16:00,641
I am the same guy who took 2,5 extra years
to graduate from college

244
00:16:00,641 --> 00:16:03,433
because of procrastination
and depression."

245
00:16:03,433 --> 00:16:05,749
I'll conclude with a wish:

246
00:16:05,749 --> 00:16:08,234
I'd like to see Zimbardo's guys

247
00:16:08,234 --> 00:16:11,952
who are wiping out and their
caregivers and the experts

248
00:16:11,952 --> 00:16:15,903
listen to the thousands of men
who are teaching us

249
00:16:15,903 --> 00:16:19,508
about arousal addiction by escaping it.

250
00:16:19,508 --> 00:16:20,917
Thanks for listening.

251
00:16:20,917 --> 00:16:24,270
(Applause)
