Inspired by the last talker
00:00:09
I'm gonna have a little song
about Internet porn.
00:00:12
No, just kidding.
00:00:15
The widespread use of Internet porn
is one of the fastes moving
00:00:19
most global experiment ever
unconsciously conducted.
00:00:23
Nearly every young guy with Internet access
becomes an eager test subject.
00:00:30
Canadian researcher
Simon Lajeunesse found
00:00:32
that most boys
seek pornography by age 10.
00:00:36
Driven by a brain that is suddenly
fascinated by sex.
00:00:41
Now, users perceive Internet porn
as far more compelling
00:00:45
than porn of the past.
Why is that?
00:00:48
Unending novelty.
00:00:50
In this Australian experiment,
00:00:52
it's not mere nudity but novelty
that gets arousals skyrocketing.
00:00:57
Subjects watch 22 porn displays.
See that spike?
00:01:01
That's where searchers switch to porn
the guys hadn't seen before.
00:01:06
What happened?
The erections in their brains fired up.
00:01:11
Why all the excitement?
00:01:13
Mother nature likes to keep
a male fertilizing willing females
00:01:17
as long as any
new ones are around.
00:01:19
In that top line the ram,
00:01:22
he needs more and more time
to make with the same old you.
00:01:28
But if you keep switching females
-- the bottom line -- well she's not the same.
00:01:37
He can get the job done in 2 minutes flat
and keep going until he's utterly exhausted.
00:01:43
This is known
as the Coolidge effect.
00:01:46
Without the Coolidge effect
there would be no Internet porn.
00:01:51
This old mammalian program
the Coolidge effect perceives
00:01:54
each novel female on a guy's screen
as a genetic opportunity.
00:02:02
To keep a guy fertilizing
the screen his brain releases
00:02:06
the "go get it" neurochemical dopamine
for each novel made or image.
00:02:11
Eventually the ram will tire
00:02:13
but as long as
the guy can keep clicking
00:02:15
he can keep going
as so will his dopamine.
00:02:18
With internet porn a guy can see
more hot babes in 10 minutes
00:02:22
than his ancestors could see
in several lifetimes.
00:02:27
The problem is he has
a hunter-gather brain.
00:02:31
A heavy user brain rewires
itself to this genetic bonanza
00:02:37
so it carefully becomes associated
with this porn harem.
00:02:44
Such behaviours that are associated
with this are being alone,
00:02:48
voyeurism, clicking,
searching, multiple tabs
00:02:52
fast-forwarding, constant novelty shock
and surprise.
00:02:57
As one young guy once asked:
00:02:59
Are we the first generation
to masturbate left handed?
00:03:04
Now, real sex, in contrast,
is courtship, touching,
00:03:09
being touched, smells, pheromones,
emotional connection,
00:03:13
interaction with a real person.
00:03:17
Now, what happens when our guy
finally gets with a real mate.
00:03:23
Well, researchers don't know
much about the effects
00:03:26
of Internet porn for several reasons.
00:03:29
In 2009, when Lajeunesse
tried to study porn'’s impact
