172 00:13:16,720 --> 00:13:22,880 To find out more, we need to understand why Facebook became so popular. 173 00:13:33,440 --> 00:13:39,360 On the 24th May 2007, just ten days after his 23rd birthday, 174 00:13:39,360 --> 00:13:45,320 Mark Zuckerberg shuffled onto this hall and explained the secret of Facebook's triumphant success. 175 00:13:47,200 --> 00:13:49,480 Today, together, 176 00:13:49,480 --> 00:13:51,800 we are going to start a movement. 177 00:13:55,240 --> 00:14:00,880 At Facebook, we're pushing for the world to be a more open place and we do this by... 178 00:14:00,880 --> 00:14:04,600 Zuckerberg's aim was that Facebook would become the destination to connect 179 00:14:04,600 --> 00:14:11,040 to friends and share information - text, photos or social events. 180 00:14:11,040 --> 00:14:13,960 All that you need to do is sign up... 181 00:14:16,040 --> 00:14:19,080 create a profile, find your mates 182 00:14:19,080 --> 00:14:23,840 and have them agree to become your Facebook friend. 183 00:14:25,720 --> 00:14:29,920 In this way, each Facebook member carves out their own group 184 00:14:29,920 --> 00:14:33,000 of friends, all within the larger network. 185 00:14:33,000 --> 00:14:36,920 What we are building is a massive network of real connections between people, 186 00:14:36,920 --> 00:14:40,920 through which information can flow more efficiently than it ever has in the past. 187 00:14:40,920 --> 00:14:43,480 And it's changing the way the world works. 188 00:14:49,240 --> 00:14:53,320 But to change the way the world works or putting it a bit more cynically, 189 00:14:53,320 --> 00:14:55,800 to build up marketing potential, 190 00:14:55,800 --> 00:14:59,520 Facebook needs to attract a huge number of users. 191 00:15:02,760 --> 00:15:04,720 What Facebook is trying to achieve 192 00:15:04,720 --> 00:15:06,960 is something called a network effect. 193 00:15:06,960 --> 00:15:09,200 This is a term coined 100 years ago 194 00:15:09,200 --> 00:15:12,880 by American telephone industrialist, Theodore Vail. 195 00:15:15,160 --> 00:15:18,520 This is the essence of what Theodore Vail outlined. 196 00:15:18,520 --> 00:15:21,520 If you have a telephone, just one... 197 00:15:24,200 --> 00:15:27,280 it's pretty useless because you can pick it up, but there is nobody 198 00:15:27,280 --> 00:15:30,800 on the other side, there is no one to make a connection with. 199 00:15:30,800 --> 00:15:33,760 But...if you add another telephone... 200 00:15:35,000 --> 00:15:37,200 ..add another and another 201 00:15:37,200 --> 00:15:38,920 and another 202 00:15:38,920 --> 00:15:40,440 and another 203 00:15:40,440 --> 00:15:43,280 this guy can talk with this guy, 204 00:15:43,280 --> 00:15:47,880 who can talk with this guy, who can talk with this guy... 205 00:15:47,880 --> 00:15:50,880 and so on and so on. 206 00:15:50,880 --> 00:15:52,920 The more phones you have connected, 207 00:15:52,920 --> 00:15:55,400 the more benefits for the individual users, 208 00:15:55,400 --> 00:15:59,240 because the user has more possibilities of people to connect with. 209 00:15:59,240 --> 00:16:03,760 And the more people that they can connect with, the more other people will want to join. 210 00:16:03,760 --> 00:16:08,360 The system becomes self-sustaining and self-fulfilling. 211 00:16:08,360 --> 00:16:10,160 It's as simple as that. 212 00:16:13,360 --> 00:16:16,320 So the power and value of Facebook 213 00:16:16,320 --> 00:16:20,640 increases by the number of friends it connects. 214 00:16:20,640 --> 00:16:24,400 Many of these things are a sort of scale leads to scale. 215 00:16:24,400 --> 00:16:26,840 That is if your friends are on it, you go on it. 216 00:16:26,840 --> 00:16:29,240 You don't do some objective evaluation of, 217 00:16:29,240 --> 00:16:32,160 "This one is better in this way and that one is better in that way." 218 00:16:32,160 --> 00:16:37,520 You know, it's like why is the phone, with its dial, why did that catch on? 219 00:16:37,520 --> 00:16:41,240 Well, critical mass eventually becomes the big thing. 220 00:16:41,240 --> 00:16:45,960 For a while, Facebook forced you to be friends with somebody 221 00:16:45,960 --> 00:16:48,920 if they wanted to be friends with you. 222 00:16:48,920 --> 00:16:53,240 And that didn't happen to work for me because I was getting 10,000 friend requests a day. 223 00:16:53,240 --> 00:16:57,880 People have the experience of having thousands of friends. 224 00:16:57,880 --> 00:17:01,240 Well, no-one really has thousands of friends. It's, it's... 225 00:17:01,240 --> 00:17:05,240 either the word thousands or the word friends has to be struck out 226 00:17:05,240 --> 00:17:07,520 for that sentence to make any sense. 227 00:17:12,880 --> 00:17:15,960 We've seen how Facebook needs volume. 228 00:17:15,960 --> 00:17:21,280 The problem is the commodity it wants to accumulate is human relationships. 229 00:17:21,280 --> 00:17:24,680 So what does that mean for those relationships? 230 00:17:24,680 --> 00:17:28,520 What does it mean to have 10,000 friends? 231 00:17:28,520 --> 00:17:32,760 Could a Facebook friend be something as trivial, cheap and disposable 232 00:17:32,760 --> 00:17:36,800 as fast food, worth no more than a burger? 233 00:17:39,280 --> 00:17:42,440 Seriously, in 2009 a well-known fast food chain 234 00:17:42,440 --> 00:17:45,760 created a page on Facebook that offered the chance 235 00:17:45,760 --> 00:17:50,160 of a free Whopper for people who 'de-friended' ten of their Facebook friends. 236 00:17:50,160 --> 00:17:54,160 In less than two weeks, the love of a whopper 237 00:17:54,160 --> 00:17:58,680 proved to be stronger than 233,906 friendships. 238 00:18:02,200 --> 00:18:05,280 This brazen marketing stunt surprisingly seems to reveal 239 00:18:05,280 --> 00:18:10,800 something fascinating about the value of our Facebook friends. 240 00:18:10,800 --> 00:18:15,120 The underlying issue was, "You're on here, we're all on this Facebook, 241 00:18:15,120 --> 00:18:18,520 "we all love it, it's fun, great. But what's the point?" 242 00:18:19,840 --> 00:18:23,480 Steve Schiff was one of thousands of Facebook users who decided to 243 00:18:23,480 --> 00:18:27,520 trade in his online friends for a grilled piece of meat in a bun. 244 00:18:29,480 --> 00:18:32,680 How do you choose which, you know, to get rid of first? 245 00:18:32,680 --> 00:18:35,840 To be honest with you, it was incredibly easy. 246 00:18:35,840 --> 00:18:38,240 It was not that tough to find ten people 247 00:18:38,240 --> 00:18:42,120 that I really didn't need to have that online connection with. 248 00:18:42,120 --> 00:18:45,160 This isn't something that is happening in real life. 249 00:18:45,160 --> 00:18:46,880 So let's just cut to the chase, 250 00:18:46,880 --> 00:18:50,800 let's cut our losses, let's get our free burgers and everybody wins. 251 00:18:53,240 --> 00:18:57,040 So, if we're willing to get rid of friends for a burger, 252 00:18:57,040 --> 00:19:02,080 does that mean social networks are changing the face of friendships in the 21st century? 253 00:19:10,440 --> 00:19:16,360 Or are there some immutable aspects of human friendship that Facebook can't change? 254 00:19:17,360 --> 00:19:23,000 I need to find out more about the evolution of relationships itself. 255 00:19:23,960 --> 00:19:27,880 I'm meeting the world authority on primate groups, 256 00:19:27,880 --> 00:19:30,320 Oxford Professor Robin Dunbar. 257 00:19:32,920 --> 00:19:35,920 Can you talk me through what's going on here? 258 00:19:35,920 --> 00:19:39,440 What's the social life of a primate group all about? 259 00:19:39,440 --> 00:19:41,840 It's all about social bonding, 260 00:19:41,840 --> 00:19:44,440 personalised relationships between individuals. 261 00:19:44,440 --> 00:19:47,120 Primates live in a really intensely social world. 262 00:19:47,120 --> 00:19:49,480 They spend a lot of time grooming each other. 263 00:19:49,480 --> 00:19:53,520 That gives them the sense of bonding. 264 00:19:53,520 --> 00:19:57,440 The problem with grooming is it's a sort of a one-on-one activity. 265 00:19:57,440 --> 00:20:00,840 It just sets an upper limit on the size of groups in the end, so the 266 00:20:00,840 --> 00:20:06,400 most social species only have average group size of 50 or 60 in primates. 267 00:20:08,200 --> 00:20:11,720 In 1992, Dunbar came up with a formula that predicts the 268 00:20:11,720 --> 00:20:16,920 upper limit to the number of bonds any primate like us can ever have. 269 00:20:18,520 --> 00:20:20,640 And it's proved so reliable 270 00:20:20,640 --> 00:20:24,240 that it has become known as the Dunbar Number. 271 00:20:25,240 --> 00:20:31,200 So we sort of plugged human brains sizes into the equation and it gives this number of 150. 272 00:20:31,200 --> 00:20:35,160 And sure enough, this number turns up in all human communities. 273 00:20:35,160 --> 00:20:39,880 It turns up in the military, It turns up in average village sizes. 274 00:20:39,880 --> 00:20:43,000 It is in the Doomsday book, 1087 AD. 275 00:20:43,000 --> 00:20:45,560 It turns up in hunter gatherer communities. 276 00:20:47,680 --> 00:20:49,880 So what does the Dunbar Number mean 277 00:20:49,880 --> 00:20:53,200 for the Facebook generation, Homo Interneticus? 278 00:20:54,560 --> 00:21:00,600 Has Facebook actually changed the upper limits of friendship previously set by nature? 279 00:21:02,680 --> 00:21:07,520 When Facebook's in-house sociologist analysed all active networks, 280 00:21:07,520 --> 00:21:13,040 they found that sure enough, nature is playing out online. 281 00:21:13,040 --> 00:21:19,920 The reality is that the average Facebook member currently has well below Dunbar's upper limit of 150. 282 00:21:19,920 --> 00:21:24,200 In fact, the number of Facebook friends they interact with on 283 00:21:24,200 --> 00:21:29,720 a daily basis is surprisingly small, typically only five or six. 284 00:21:31,920 --> 00:21:35,600 So while you can claim you have this huge network of 285 00:21:35,600 --> 00:21:38,320 people you know in some vague sense, 286 00:21:38,320 --> 00:21:42,960 most of those relationships I wouldn't call relationships. 287 00:21:42,960 --> 00:21:44,840 They're voyeurs. 288 00:21:50,640 --> 00:21:54,920 So through the Dunbar Number, we've found that Facebook's drive 289 00:21:54,920 --> 00:21:58,560 for network effect isn't changing our relationships. 290 00:22:02,360 --> 00:22:05,800 For me, there is something deeper going on, 291 00:22:05,800 --> 00:22:08,520 beyond this superficial issue of numbers. 292 00:22:09,520 --> 00:22:12,280 The point about Facebook is that it does something else 293 00:22:12,280 --> 00:22:17,080 to relationships, it puts them in a constant loop 294 00:22:17,080 --> 00:22:18,680 of digital information. 295 00:22:19,480 --> 00:22:23,920 To understand what that means, we need go back to the very origins 296 00:22:23,920 --> 00:22:26,080 of the phrase "in the loop" 297 00:22:26,080 --> 00:22:31,000 and some important science developed in the Second World War. 298 00:22:31,000 --> 00:22:33,720 WAILING OF AIR RAID SIRENS 299 00:22:33,720 --> 00:22:37,080 'The enemy again and again broke through the coastal defences.' 300 00:22:41,280 --> 00:22:44,840 Night after the night, the brave anti-aircraft gunners stood 301 00:22:44,840 --> 00:22:48,560 by their posts and tried in vain to shoot down the German bombers. 302 00:22:48,560 --> 00:22:54,080 British military scientists realised they were facing a grave problem. 303 00:22:59,080 --> 00:23:02,360 The problem that the anti-aircraft gunners had was 304 00:23:02,360 --> 00:23:05,040 that while the radar could spot the planes, 305 00:23:05,040 --> 00:23:09,120 and the gunners could fire at them, they still missed the target. 306 00:23:12,400 --> 00:23:16,640 It would be an American mathematician, Norbert Wiener, 307 00:23:16,640 --> 00:23:18,840 who would provide the answer. 308 00:23:18,840 --> 00:23:22,360 When Wiener heard what was facing the British gunners, 309 00:23:22,360 --> 00:23:24,320 he decided to come up with a solution 310 00:23:24,320 --> 00:23:27,200 that tackled the problem in a completely different way. 311 00:23:28,280 --> 00:23:34,880 Wiener asked a simple question, "When we walk, why don't we fall over?" 312 00:23:34,880 --> 00:23:38,880 Wiener argued that what keeps us upright is a constant loop of 313 00:23:38,880 --> 00:23:41,760 information to and from the brain, 314 00:23:41,760 --> 00:23:47,560 a loop of action and reaction that allows us to predict future action. 315 00:23:47,560 --> 00:23:51,360 So Wiener saw the gunner, his gun, the plane 316 00:23:51,360 --> 00:23:54,720 and the pilot not as separate entities, 317 00:23:54,720 --> 00:23:59,480 but all embedded in the same loop of continuous feedback. 318 00:23:59,480 --> 00:24:01,440 Only through thinking in this way, 319 00:24:01,440 --> 00:24:03,840 linking human and machine together as one, 320 00:24:03,840 --> 00:24:06,800 could the gunners successfully hit their targets. 321 00:24:08,320 --> 00:24:17,280 One of the big innovations of Facebook is to apply this constant action and reaction to friendship. 322 00:24:17,280 --> 00:24:20,640 In fact, I believe that they are key in understanding 323 00:24:20,640 --> 00:24:24,640 how our online relationships have transformed forever. 324 00:24:32,280 --> 00:24:38,880 What Facebook pioneered before anyone else was status updates fed between friends in real time. 325 00:24:46,520 --> 00:24:49,760 But at the beginning, it wasn't like that. 326 00:24:49,760 --> 00:24:55,360 Back in 2004, it was a simple college student website. 327 00:24:55,360 --> 00:24:59,400 Legend has it that one night after a bad date, Mark came back and hacked 328 00:24:59,400 --> 00:25:02,000 into the student database to create a website 329 00:25:02,000 --> 00:25:04,160 for rating all of the women on campus. 330 00:25:04,160 --> 00:25:08,200 Two hours later, 80% of the student population had voted, 331 00:25:08,200 --> 00:25:11,600 crashing the entire student computer servers. 332 00:25:15,320 --> 00:25:20,360 Mark was the type of person who was always thinking of 333 00:25:20,360 --> 00:25:24,000 technical solutions to social problems. 334 00:25:24,000 --> 00:25:27,040 Seeing the demand for connection, 335 00:25:27,040 --> 00:25:30,320 Zuckerberg started a new venture, Facebook. 336 00:25:31,840 --> 00:25:34,240 I built the first version of Facebook in a couple 337 00:25:34,240 --> 00:25:38,880 of weeks in my dorm room at Harvard. I built it because I wanted 338 00:25:38,880 --> 00:25:42,400 the people around me, the students at Harvard, to be able 339 00:25:42,400 --> 00:25:45,520 to share information and stay connected better. 340 00:25:45,520 --> 00:25:48,640 I emailed a few of my friends and they emailed a few of their friends 341 00:25:48,640 --> 00:25:50,520 and within a few days, I think, 342 00:25:50,520 --> 00:25:52,680 thousands of people were on it at Harvard. 343 00:25:56,360 --> 00:25:58,680 All of us, particularly students caught in the social 344 00:25:58,680 --> 00:26:04,160 whirl of college life, crave news and gossip about our friends. 345 00:26:04,160 --> 00:26:08,440 But Zuckerberg realised that while the web made information available, 346 00:26:08,440 --> 00:26:10,760 people didn't always know it was there. 347 00:26:14,240 --> 00:26:17,160 The problem was browsing Facebook was like poking your head into 348 00:26:17,160 --> 00:26:20,400 someone's room every time you wanted to find out what they were doing. 349 00:26:20,400 --> 00:26:25,200 You had to go to your friend's pages every day or you missed something crucial they posted. 350 00:26:25,200 --> 00:26:28,040 If you missed something crucial, then you didn't respond 351 00:26:28,040 --> 00:26:31,560 and if you didn't respond, your friend though nobody was watching 352 00:26:31,560 --> 00:26:34,280 and what's the point in bragging if nobody cares? 353 00:26:38,280 --> 00:26:43,040 What changed everything is what Zuckerberg did next. 354 00:26:43,040 --> 00:26:50,560 He completed the loop of information on Facebook with something he called "News Feed". 355 00:26:50,560 --> 00:26:57,600 It meant that anything you posted on your site is instantly broadcast to all your friends and vice versa. 356 00:26:57,600 --> 00:27:03,560 They don't have to go looking at your site, all updates came to them. 357 00:27:03,560 --> 00:27:07,040 We launched the product at midnight. 358 00:27:07,040 --> 00:27:09,960 We were convinced that people were going to love it. 359 00:27:09,960 --> 00:27:13,840 And we thought, "This is the kind of thing that could change the web." 360 00:27:24,360 --> 00:27:29,920 It seems all so normal now, but at the time, Facebook users hated it. 361 00:27:29,920 --> 00:27:33,040 They saw it as an appalling intrusion into their lives, 362 00:27:33,040 --> 00:27:37,280 a terrible wrench from the Facebook they were used to. 363 00:27:37,280 --> 00:27:40,760 The first thing I saw was that someone had broken up with someone 364 00:27:40,760 --> 00:27:42,400 and so when I saw those things, 365 00:27:42,400 --> 00:27:45,080 I just kind, I was really put into shock, I was like, 366 00:27:45,080 --> 00:27:47,040 "That's so much stuff broadcasting." 367 00:27:47,040 --> 00:27:49,760 Then I realised that all my stuff was being broadcast 368 00:27:49,760 --> 00:27:52,320 in the same way too, and I didn't really want that. 369 00:27:53,840 --> 00:27:57,200 As soon as we launched the product, we started looking at the feedback 370 00:27:57,200 --> 00:28:01,160 coming in from our users and it was universally bad. 371 00:28:02,120 --> 00:28:07,560 It was, "I want my homepage back. I don't like this, please turn it off." 372 00:28:07,560 --> 00:28:10,960 I was emailed by almost everyone I knew on Facebook to say, 373 00:28:10,960 --> 00:28:12,480 "Why did you do this to us?" 374 00:28:12,480 --> 00:28:16,280 It was personal. And right before we were leaving, I think we were called 375 00:28:16,280 --> 00:28:18,440 and told there were security guards coming 376 00:28:18,440 --> 00:28:20,840 because there was going to be a protest outside. 377 00:28:20,840 --> 00:28:22,680 This was hours after we launched. 378 00:28:22,680 --> 00:28:24,920 I started to make a protest against it, 379 00:28:24,920 --> 00:28:28,600 and created a group called Students Against Facebook News Feed. 380 00:28:28,600 --> 00:28:30,760 By the third or fourth day, at its apex, 381 00:28:30,760 --> 00:28:34,640 it was at 750,000 people in the group. 382 00:28:36,360 --> 00:28:38,320 But Zuckerberg stuck to his guns. 383 00:28:38,320 --> 00:28:43,880 He was determined that Facebook users would live life in the loop. 384 00:28:43,880 --> 00:28:47,880 Within a few days, we could see in our stats already that just the amount of page views 385 00:28:47,880 --> 00:28:52,120 that people were doing and the amount of engagement that they had on the site was going up, 386 00:28:52,120 --> 00:28:54,600 because what they were coming on the site to do was to see 387 00:28:54,600 --> 00:28:57,720 what their friends were doing day to day and this made it so much easier. 388 00:29:01,320 --> 00:29:04,960 It's this culture of real time updating and not the numbers 389 00:29:04,960 --> 00:29:08,640 of friends that is the big shift in all of our relationships. 390 00:29:08,640 --> 00:29:13,680 Constant status updates, this being in the online loop, 391 00:29:13,680 --> 00:29:16,640 has dragged the web into a new age, 392 00:29:16,640 --> 00:29:21,360 inspiring many imitators, most famously, Twitter. 393 00:29:21,360 --> 00:29:25,960 But more importantly, what does this shift mean for you and me 394 00:29:25,960 --> 00:29:27,920 as we live our daily lives? 395 00:29:30,720 --> 00:29:34,920 I'm going to meet Sherry Turkle, an eminent clinical psychologist 396 00:29:34,920 --> 00:29:39,200 who's been studying our relationship with technology for 20 years. 397 00:29:39,200 --> 00:29:42,840 She's actively researching how the webs feedback loops 398 00:29:42,840 --> 00:29:45,080 challenge our sense of who we are. 399 00:29:46,680 --> 00:29:52,320 I think you've started to get almost a new personality type. 400 00:29:52,320 --> 00:29:57,320 It moves from, "I have a feeling, I want to make a call," 401 00:29:57,320 --> 00:30:03,160 to, "I want to have a feeling, I need to make a call." 402 00:30:03,160 --> 00:30:08,240 There is a sense in which you almost need the validation and the support 403 00:30:08,240 --> 00:30:11,800 of the community to in fact feel the feeling in the first place. 404 00:30:11,800 --> 00:30:14,040 Bringing other people into the loop 405 00:30:14,040 --> 00:30:17,120 of feeling your feeling, this is very seductive. 406 00:30:17,120 --> 00:30:20,040 So as a recipient of all of this information, 407 00:30:20,040 --> 00:30:22,520 how do you think this is affecting me? 408 00:30:22,520 --> 00:30:26,560 You start to want to hide.

How happy would you be? 504 00:37:26,480 --> 00:37:34,360 I still think that books are at the heart of what it means to be educated and to try and educate. 505 00:37:34,360 --> 00:37:39,600 And I think the generation of students that I teach see books as peripheral. 506 00:37:39,600 --> 00:37:44,600 I happen to think that long-form reading is very important because you 507 00:37:44,600 --> 00:37:50,480 can learn things from long form that you can never learn from short form. 508 00:37:50,480 --> 00:37:53,440 You know, you can't read Remains Of The Day 509 00:37:53,440 --> 00:37:57,680 and not come away with a better understanding of life regret. 510 00:37:57,680 --> 00:38:00,800 And those are things that you can only get 511 00:38:00,800 --> 00:38:04,040 in sort of book-length reading sessions. 512 00:38:06,040 --> 00:38:09,320 But are these just the grumblings of an older generation? 513 00:38:09,320 --> 00:38:16,040 Beyond anecdotes, can we find any evidence that the web is really changing how we think? 514 00:38:18,360 --> 00:38:20,400 At University College London, 515 00:38:20,400 --> 00:38:24,800 Professor David Nicolas was the first academic to systematically 516 00:38:24,800 --> 00:38:27,520 study people's online behaviour 517 00:38:27,520 --> 00:38:31,680 by analysing millions of anonymous data records. 518 00:38:31,680 --> 00:38:35,240 In one survey, he found that 40% of people 519 00:38:35,240 --> 00:38:38,120 never revisit the same web page, 520 00:38:38,120 --> 00:38:41,200 that they only view up to three pages from thousands 521 00:38:41,200 --> 00:38:42,840 that are available online. 522 00:38:44,720 --> 00:38:48,680 The really big surprise was that people seemed to be skipping 523 00:38:48,680 --> 00:38:50,520 over the virtual landscape. 524 00:38:50,520 --> 00:38:53,480 They were popping in from sites, looking at one or two pages 525 00:38:53,480 --> 00:38:57,160 going to another site, looking at one or two pages and then going on. 526 00:38:57,160 --> 00:39:00,760 Nobody seemed to be staying anywhere for very long. 527 00:39:02,000 --> 00:39:06,920 Professor David Nicolas's study hints that the web's hyperlinked 528 00:39:06,920 --> 00:39:11,080 network of information may be converting us from thinking linearly 529 00:39:11,080 --> 00:39:12,800 to thinking associatively. 530 00:39:14,320 --> 00:39:19,000 These two types of thinking can be termed fox and hedgehog. 531 00:39:19,960 --> 00:39:22,880 Foxes are people that embrace all kinds of ideas, 532 00:39:22,880 --> 00:39:26,080 like the wisdom of the crowd, bounce from here and there 533 00:39:26,080 --> 00:39:29,280 and pick things up and that's how they acquire their knowledge. 534 00:39:29,280 --> 00:39:30,920 Then there are hedgehogs. 535 00:39:30,920 --> 00:39:33,880 Hedgehogs like one big idea, they repeat, 536 00:39:33,880 --> 00:39:36,160 they go back to the same source. 537 00:39:36,160 --> 00:39:39,880 These people like the peer-evaluated environment because they are certain of that. 538 00:39:39,880 --> 00:39:42,440 These people represent quite a different group of people. 539 00:39:45,920 --> 00:39:52,040 Now we want to find out whether the younger generations are becoming more fox like than hedgehog. 540 00:39:52,040 --> 00:39:56,840 So we've joined forces with UCL in a unique experiment, that you too 541 00:39:56,840 --> 00:40:02,360 can take part in online, to find out which species of web animal you are. 542 00:40:02,360 --> 00:40:08,440 Our aim is to discover the impact the web is having on our brains. 543 00:40:12,720 --> 00:40:14,640 Is this test a genuine first? 544 00:40:14,640 --> 00:40:16,520 Absolute first, a global first. 545 00:40:16,520 --> 00:40:20,080 Nobody has ever done this before. Nobody even knows what will come out of it. 546 00:40:22,200 --> 00:40:27,440 To give us a first indication, we've brought together 100 people who represent different ages, genders. 547 00:40:27,440 --> 00:40:32,280 Some use the web rarely, others all the time. 548 00:40:32,280 --> 00:40:36,400 Look at your screen, concentrate on what you have to do, click start and that game will begin. 549 00:40:37,920 --> 00:40:42,480 We are especially interested in the 12 and 18-year-old age groups because 550 00:40:42,480 --> 00:40:46,960 their brains have been formed only knowing life with the web. 551 00:40:46,960 --> 00:40:51,120 How does their behaviour compare to people who rarely use the web 552 00:40:51,120 --> 00:40:53,200 and to serial users like myself? 553 00:40:54,720 --> 00:40:58,920 Got to look at the pictures, got to look at the numbers, got to look at the letters, got to make a decision. 554 00:40:58,920 --> 00:41:03,080 Is it an odd number, is it an even number, is it a vowel, is it a consonant? Aagghh. 555 00:41:03,080 --> 00:41:05,800 It's a bit too much for my brain. 556 00:41:05,800 --> 00:41:09,920 The results from our initial survey of 100 volunteers seem 557 00:41:09,920 --> 00:41:12,000 to confirm what many suspect. 558 00:41:12,000 --> 00:41:18,120 Generation Web seemed to display more fox-like behaviour. 559 00:41:18,120 --> 00:41:19,840 They answered their questions 560 00:41:19,840 --> 00:41:22,440 after looking at half the number of web pages 561 00:41:22,440 --> 00:41:25,320 and only spending one sixth of the time viewing the information 562 00:41:25,320 --> 00:41:27,120 that their elders did. 563 00:41:37,120 --> 00:41:40,920 So it seems pretty clear to me that for good or ill, 564 00:41:40,920 --> 00:41:44,440 the younger generation is being remoulded by the web. 565 00:41:44,440 --> 00:41:48,800 Facebook's feedback loops are revolutionising how they relate. 566 00:41:48,800 --> 00:41:53,040 There's empirical evidence now that information overload and associative 567 00:41:53,040 --> 00:41:56,200 thinking may be reshaping how they think. 568 00:41:56,200 --> 00:42:00,240 For many, this seems to be a bleak prospect. 569 00:42:00,240 --> 00:42:04,880 Young people, bouncing and flitting through a thoughtless, throwaway virtual world. 570 00:42:04,880 --> 00:42:07,280 But are we being too harsh?
