WEBVTT 00:00:07.497 --> 00:00:09.138 Inspired by the last talker 00:00:09.138 --> 00:00:12.983 I'm going to have a little song about Internet porn. 00:00:12.983 --> 00:00:15.515 No, just kidding. 00:00:15.515 --> 00:00:19.620 The widespread use of Internet porn is one of the fastest moving 00:00:19.620 --> 00:00:23.749 most global experiments ever unconsciously conducted. 00:00:23.749 --> 00:00:26.734 Nearly every young guy with an Internet access 00:00:26.734 --> 00:00:29.446 becomes an eager test subject. 00:00:30.072 --> 00:00:32.459 Canadian researcher Simon Lajeunesse found 00:00:32.459 --> 00:00:36.327 that most boys seek pornography by age 10. 00:00:36.327 --> 00:00:41.338 Driven by a brain that is suddenly fascinated by sex. 00:00:41.338 --> 00:00:45.134 Now, users perceive Internet porn as far more compelling 00:00:45.134 --> 00:00:46.684 than porn of the past. 00:00:46.684 --> 00:00:48.048 Why is that? 00:00:48.048 --> 00:00:50.680 Unending novelty. 00:00:50.680 --> 00:00:52.379 In this Australian experiment, 00:00:52.379 --> 00:00:57.882 it's not mere nudity but novelty that gets arousals skyrocketing. 00:00:57.882 --> 00:01:01.567 Subjects watch 22 porn displays. See that spike? 00:01:01.567 --> 00:01:04.642 That's where the researchers switch to porn 00:01:04.642 --> 00:01:06.782 the guys hadn't seen before. 00:01:06.782 --> 00:01:11.705 What happened? Their erections and their brains fired up. 00:01:11.705 --> 00:01:13.499 Why all the excitement? 00:01:13.499 --> 00:01:17.421 Mother nature likes to keep a male fertilizing willing females 00:01:17.421 --> 00:01:19.942 as long as any new ones are around. 00:01:19.942 --> 00:01:22.393 In that top line the ram, 00:01:22.393 --> 00:01:28.283 he needs more and more time to make with the same old ewe. 00:01:28.283 --> 00:01:37.030 But if you keep switching females - the bottom line - well she's not the same. 00:01:37.030 --> 00:01:39.997 He can get the job done in 2 minutes flat 00:01:39.997 --> 00:01:43.617 and keep going until he's utterly exhausted. 00:01:43.617 --> 00:01:46.445 This is known as the Coolidge effect. 00:01:46.445 --> 00:01:51.324 Without the Coolidge effect there would be no Internet porn. 00:01:51.324 --> 00:01:54.886 This old mammalian program, the Coolidge effect, perceives 00:01:54.886 --> 00:02:02.159 each novel female on a guy's screen as a genetic opportunity. 00:02:02.159 --> 00:02:06.052 To keep a guy fertilizing the screen his brain releases 00:02:06.052 --> 00:02:11.835 the "go get it" neurochemical dopamine for each novel mate or image. 00:02:11.835 --> 00:02:13.800 Eventually the ram will tire 00:02:13.800 --> 00:02:15.787 but as long as the guy can keep clicking 00:02:15.787 --> 00:02:18.742 he can keep going and so will his dopamine. 00:02:18.742 --> 00:02:22.826 With internet porn a guy can see more hot babes in 10 minutes 00:02:22.826 --> 00:02:27.459 than his ancestors could see in several lifetimes. 00:02:27.459 --> 00:02:31.342 The problem is he has a hunter-gather brain. 00:02:31.342 --> 00:02:37.523 A heavy user brain rewires itself to this genetic bonanza 00:02:37.523 --> 00:02:44.271 so it carefully becomes associated with this porn harem. 00:02:44.287 --> 00:02:48.698 Such behaviours that are associated with this are being alone, 00:02:48.698 --> 00:02:52.250 voyeurism, clicking, searching, multiple tabs 00:02:52.250 --> 00:02:57.295 fast-forwarding, constant novelty, shock and surprise. 00:02:57.295 --> 00:02:59.095 As one young guy once asked: 00:02:59.095 --> 00:03:04.415 Are we the first generation to masturbate left handed? 00:03:04.415 --> 00:03:09.480 Now, real sex, in contrast, is courtship, touching, 00:03:09.480 --> 00:03:13.669 being touched, smells, pheromones, emotional connection, 00:03:13.669 --> 00:03:17.031 interaction with a real person. 00:03:17.031 --> 00:03:23.435 Now, what happens when our guy finally gets with a real mate. 00:03:23.435 --> 00:03:26.614 Well, researchers don't know much about the effects 00:03:26.614 --> 00:03:29.644 of Internet porn for several reasons. 00:03:29.644 --> 00:03:34.774 In 2009, when Lajeunesse tried to study porn's impact 00:03:34.774 --> 00:03:39.717 he couldn't find any college age males who weren't using it. 00:03:39.717 --> 00:03:45.659 So the first serious dilemma is that studies have no control groups. 00:03:45.659 --> 00:03:48.973 Now, this creates a huge blind spot. 00:03:48.973 --> 00:03:52.852 Imagine if all guys started smoking at age 10 00:03:52.852 --> 00:03:55.122 and there were no groups that didn't. 00:03:55.122 --> 00:03:59.890 We would think that lung cancer is normal for all guys. 00:03:59.890 --> 00:04:05.898 Undaunted by his lack of non-users Lajeunesse asked 20 male students: 00:04:05.898 --> 00:04:11.185 Is Internet porn affecting you or your attitude towards women? 00:04:11.185 --> 00:04:14.353 They answered, "No, I don't think so." 00:04:14.353 --> 00:04:16.835 But they've been using it for about a decade then 00:04:16.835 --> 00:04:19.185 pretty much non-stop. 00:04:19.185 --> 00:04:24.361 This is like asking a fish what it thinks about water? 00:04:24.361 --> 00:04:26.892 Which bring us to a second problem. 00:04:26.892 --> 00:04:31.331 Researchers haven't asked porn users about the symptoms 00:04:31.331 --> 00:04:35.539 Zimbardo described in "The Demise of Guys." 00:04:35.539 --> 00:04:38.250 Arousal addiction symptoms are easily mistaken 00:04:38.250 --> 00:04:44.370 for such things as ADHD, social anxiety, depression, 00:04:44.370 --> 00:04:47.906 concentration problems, performance anxiety, 00:04:47.906 --> 00:04:50.326 OCD and a host of others. 00:04:50.326 --> 00:04:55.745 Now, healthcare providers often assume that these conditions are primary 00:04:55.745 --> 00:05:01.545 perhaps the cause of addiction but never really the result of an addiction. 00:05:01.545 --> 00:05:05.943 As a consequence they often medicate these guys 00:05:05.943 --> 00:05:11.292 without really inquiring about if they have an Internet addiction. 00:05:11.292 --> 00:05:13.958 Guys never realise that they could overcome these 00:05:13.958 --> 00:05:18.059 symptoms simply by changing their behaviour. 00:05:18.059 --> 00:05:21.511 Now, the third problem is it's hard to believe that 00:05:21.511 --> 00:05:26.608 sexual activity can cause addiction because sex is healthy. 00:05:26.608 --> 00:05:28.627 But Internet porn is not sex. 00:05:28.627 --> 00:05:32.807 Internet porn is as different from real sex 00:05:32.807 --> 00:05:36.867 as todays video games are from checkers. 00:05:36.867 --> 00:05:39.828 Watching the screen full of naked body parts 00:05:39.828 --> 00:05:45.212 won't automatically protect one from arousal addiction. 00:05:45.212 --> 00:05:48.579 In this Dutch study - here's the title - 00:05:48.579 --> 00:05:53.435 they found that in fact of all activities on the Internet 00:05:53.435 --> 00:05:57.045 porn has the most potential to become addictive. 00:05:57.045 --> 00:05:58.216 Here's why. 00:05:58.216 --> 00:06:00.618 This ancient programme, the reward circuit, 00:06:00.618 --> 00:06:04.773 evolved to drive us towards natural rewards 00:06:04.773 --> 00:06:09.195 such as sex, bonding and food. 00:06:09.195 --> 00:06:13.482 As a consequence extreme versions of natural rewards 00:06:13.482 --> 00:06:17.747 have a unique ability to capture us. 00:06:17.747 --> 00:06:22.422 For example: high-calorie foods or hot novel babes 00:06:22.422 --> 00:06:24.892 give us extra dopamine. 00:06:24.892 --> 00:06:30.753 Too much dopamine though can override our natural satiation mechanisms. 00:06:30.753 --> 00:06:34.180 For example: give rats unlimited access 00:06:34.180 --> 00:06:39.228 to junk food and almost all of them will binge to obesity. 00:06:39.228 --> 00:06:42.665 This is also why 4 out of 5 Americans are overweight 00:06:42.665 --> 00:06:45.201 and about half of those are obese. 00:06:45.201 --> 00:06:47.006 That is addicted to food. 00:06:47.006 --> 00:06:51.366 Now, in contrast to natural rewards, drugs such as 00:06:51.366 --> 00:06:55.732 cocaine or alcohol only hook about 10% of users 00:06:55.732 --> 00:06:58.484 whether they are rats or humans. 00:06:59.521 --> 00:07:06.933 This binge mechanism for food or sex was once an evolutionary advantage. 00:07:06.933 --> 00:07:10.381 In essence, it is getting it while the getting is good. 00:07:10.381 --> 00:07:14.152 Now, you can think of wolves packing away 20 pound of meat per kill 00:07:14.152 --> 00:07:18.433 or it's mating season and you're the alpha male. 00:07:18.433 --> 00:07:21.872 What if mating season never ends? 00:07:21.872 --> 00:07:26.071 All those hits of dopamine can tell your brain to do two things. 00:07:26.071 --> 00:07:30.011 First they say, "Man, you've hit the evolutionary jackpot." 00:07:30.011 --> 00:07:35.745 Second, they kick in a molecular switch called Delta-FosB. 00:07:35.745 --> 00:07:39.738 I know it is a fancy word, but dopamine kicks in Delta-FosB 00:07:39.738 --> 00:07:44.657 and that starts to accumulate in the brain's reward circuit. 00:07:44.657 --> 00:07:48.974 Now, with excess chronic consumption of drugs or natural rewards, 00:07:48.974 --> 00:07:52.969 this build up a Delta-FosB starts to alter the brain 00:07:52.969 --> 00:07:57.947 and promotes the cycle of binging and craving. 00:07:57.947 --> 00:08:01.217 If the binging continues the Delta-FosB builds up 00:08:01.217 --> 00:08:04.611 and it can lead to brain changes seen in all addicts. 00:08:04.611 --> 00:08:08.230 So the dominos are excess consumption 00:08:08.230 --> 00:08:12.554 excess dopamine, Delta-FosB, brain changes. 00:08:12.554 --> 00:08:16.480 One of the first changes is a numbed pleasure response. 00:08:16.480 --> 00:08:23.931 It kicks in, and so everyday pleasures really don't satisfy a porn addict. 00:08:23.931 --> 00:08:26.741 At the same time other physical changes in the brain 00:08:26.741 --> 00:08:29.647 make the brain hyper-reactive to porn. 00:08:29.647 --> 00:08:33.159 Everything else in the porn user's life is sort of boring, 00:08:33.172 --> 00:08:35.529 but porn is super exciting. 00:08:35.529 --> 00:08:40.111 Finally his willpower erodes as his frontal cortex changes. 00:08:40.111 --> 00:08:41.988 I can't emphasize this enough. 00:08:41.988 --> 00:08:45.462 All addictions share these same brain changes 00:08:45.462 --> 00:08:52.032 and the same molecular switch that kicks them in - Delta-FosB. 00:08:52.032 --> 00:08:55.020 Now scientists have used brain scans to measure 00:08:55.020 --> 00:08:57.336 these changes in drug addicts. 00:08:57.336 --> 00:09:02.055 Up-here these scans show a reduced pleasure response in drug addicts. 00:09:02.055 --> 00:09:06.590 These and several other changes have also been seen in gambling addicts, 00:09:06.590 --> 00:09:10.622 food addicts, very recently in video game addicts 00:09:11.322 --> 00:09:13.622 and now in internet addicts. 00:09:13.622 --> 00:09:16.767 I apologize for filling up the slide with brain studies. 00:09:16.767 --> 00:09:18.947 Just notice the dates. 00:09:18.947 --> 00:09:22.387 But I want you to know that they exist. 00:09:22.660 --> 00:09:27.175 So far all brain research points only in one direction. 00:09:27.175 --> 00:09:32.780 Constant novelty at the click can cause addiction. 00:09:32.780 --> 00:09:36.506 We know this because when scientist examined 00:09:36.506 --> 00:09:38.425 former Internet addicts they found 00:09:38.425 --> 00:09:42.367 that these brain changes were reversing themselves. 00:09:42.367 --> 00:09:46.988 Unfortunately, none of these studies isolate porn users, 00:09:46.988 --> 00:09:49.124 but they do include them. 00:09:49.124 --> 00:09:51.413 Here's the game changer. 00:09:51.413 --> 00:09:55.622 At last we have a group of guys who are no longer using Internet porn. 00:09:55.622 --> 00:10:01.592 That's right!
