0:01:10.106,0:01:12.372 That's when I knew I had to do something 0:01:12.372,0:01:15.207 to stop this from ever happening again. 0:01:15.207,0:01:18.518 But the pain and the misery[br]that Rebecca endured 0:01:18.518,0:01:20.544 had already happened. 0:01:20.544,0:01:23.885 The damage was done. 0:01:23.885,0:01:25.578 My name is Trisha Prabhu, 0:01:25.578,0:01:27.125 I'm fourteen years old, 0:01:27.125,0:01:29.139 and I'm from the great city of Naperville, 0:01:29.139,0:01:31.349 in Illionois, in the United States. 0:01:31.349,0:01:33.779 I'm passionate to stop cyberbullying 0:01:33.779,0:01:37.567 at the source, before the damage is done. 0:01:37.567,0:01:40.430 I'm a big dreamer,[br]and I believe that everyone 0:01:40.430,0:01:43.796 should have the right to dream,[br]persist in their dream, 0:01:43.796,0:01:47.690 and see that become a reality. 0:01:47.690,0:01:49.904 So, when I read Rebecca's story, 0:01:49.904,0:01:51.601 I immediately wondered, 0:01:51.601,0:01:53.834 "Were there any others like her out there, 0:01:53.834,0:01:56.105 that were suffering as well?" 0:01:56.105,0:02:01.220 I'd soon learn that she was one[br]of a countless many. 0:02:02.280,0:02:07.572 Megan Meier died three weeks[br]before her fourteenth birthday. 0:02:08.652,0:02:12.634 She hung herself in her bedroom closet 0:02:12.634,0:02:14.282 where her mother would find her 0:02:14.282,0:02:17.089 when coming up to get her for dinner. 0:02:18.639,0:02:20.401 She'd received messages like, 0:02:20.401,0:02:23.312 "The world would be[br]a better place without you", 0:02:23.312,0:02:25.675 on her Myspace account. 0:02:26.665,0:02:28.436 The damage was done, 0:02:28.436,0:02:31.649 and Megan suffered the consequences. 0:02:32.499,0:02:36.303 Tyler Clementi[br]was an eighteen-year-old student 0:02:36.303,0:02:38.851 at Rutgers University. 0:02:38.851,0:02:41.359 He was just getting used to college life 0:02:41.359,0:02:43.802 and his new gay identity. 0:02:44.482,0:02:47.204 One day, his roommate and a friend 0:02:47.204,0:02:50.009 decided to use a webcam and a laptop 0:02:50.009,0:02:54.747 to stream some of Tyler's most[br]intimate moments with his boyfriend 0:02:54.747,0:02:57.068 all over social media. 0:02:57.678,0:03:00.454 The damage was done. 0:03:01.074,0:03:04.186 Humiliated, Tyler took his life, 0:03:04.186,0:03:07.416 jumping off of the[br]George Washington bridge. 0:03:08.896,0:03:11.694 I wish more than anything 0:03:11.694,0:03:14.087 that I could rewrite those stories. 0:03:14.087,0:03:17.114 I wish I could make every perpetrator 0:03:17.114,0:03:19.799 rethink what they did. 0:03:19.799,0:03:22.113 But what if I could do that? 0:03:22.113,0:03:26.587 What if I could stop the damage[br]before it was done? 0:03:26.587,0:03:31.211 Would Megan, Tyler and Rebecca[br]still be alive today? 0:03:31.211,0:03:34.870 Cyberbullying is a huge problem. 0:03:34.870,0:03:38.350 52% of adolescents[br]in the United States alone 0:03:38.350,0:03:40.516 have been cyberbullied. 0:03:40.516,0:03:42.683 And 38% of them 0:03:42.683,0:03:45.388 suffered suicidal tendencies. 0:03:45.388,0:03:48.084 Let's look at it [br]from a global perspective. 0:03:48.084,0:03:52.409 A quarter of the world's population[br]are adolescents. 0:03:52.409,0:03:55.575 We're talking 1.8 billion teens. 0:03:55.575,0:03:58.372 Imagine that[br]in the social media revolution; 0:03:58.372,0:04:01.379 how more and more of them[br]are getting on social media, 0:04:01.379,0:04:05.021 and more and more of them[br]are being cyberbullied. 0:04:06.901,0:04:09.505 So, why do you get cyberbullied? 0:04:09.505,0:04:11.656 Look, I might be biased,[br]but I'm pretty sure 0:04:11.656,0:04:15.553 that kids are not mean devils[br]that run around with cruel intentions. 0:04:15.553,0:04:18.114 I don't know about you,[br]but that's what I think. 0:04:18.114,0:04:22.091 And what about adults?[br]Are they nice or mean on social media? 0:04:22.091,0:04:24.674 Now, when it comes to adults,[br]I wasn't really sure. 0:04:24.674,0:04:28.055 So, I had to do some research[br]to figure that out. 0:04:28.055,0:04:31.233 So, that year,[br]for my science experiment at school, 0:04:31.233,0:04:34.398 I decided to look at how age[br]affected the willingness 0:04:34.398,0:04:37.725 to post offensive messages[br]on social media sites. 0:04:37.725,0:04:39.018 What did I find? 0:04:39.018,0:04:42.466 This younger age group,[br]ages twelve to eighteen, 0:04:42.466,0:04:46.203 was 40% more willing[br]to post an offensive message 0:04:46.203,0:04:47.721 than an older age group. 0:04:47.721,0:04:50.572 OK. The number didn't surprise me. 0:04:50.572,0:04:52.147 But why? 0:04:52.147,0:04:53.905 Why was that younger age group 0:04:53.905,0:04:57.469 so much more willing[br]to post an offensive message? 0:04:57.469,0:05:00.560 I started to do a lot of research, 0:05:00.560,0:05:03.411 and, one day, I came across an article, 0:05:03.411,0:05:06.456 and it had one sentence[br]that would forever change 0:05:06.456,0:05:09.351 my view on this problem. 0:05:09.351,0:05:12.218 They said, "The adolescent brain 0:05:12.218,0:05:16.094 is likened to a car with no breaks." 0:05:16.094,0:05:18.655 High speed. No pausing. 0:05:18.655,0:05:21.749 No thinking. No considering. 0:05:21.749,0:05:25.136 We just act. So why is it like that? 0:05:25.136,0:05:27.172 Our brains are kind of weird. 0:05:27.172,0:05:29.784 They develop from the back to the front, 0:05:29.784,0:05:31.895 which means[br]that our front part of the brain 0:05:31.895,0:05:35.552 is not fully developed until age 25. 0:05:36.712,0:05:38.972 Why is that a problem? 0:05:38.972,0:05:41.581 Well, prefrontal cortex 0:05:41.581,0:05:44.208 controls decision-making skills, 0:05:44.208,0:05:46.225 rash, impulsive decisions, 0:05:46.225,0:05:48.989 spur-of-the-moment feelings. 0:05:48.989,0:05:52.620 So, that's why adolescents[br]don't think before they act. 0:05:52.620,0:05:55.123 They just go ahead and do something, 0:05:55.123,0:05:58.306 whether it's downing[br]fifteen Red Bulls on a dare, 0:05:58.306,0:06:00.783 skipping an English final, 0:06:00.783,0:06:02.667 doing something crazy. 0:06:02.667,0:06:05.991 We don't really think before we do it. 0:06:06.631,0:06:09.873 Well, then I was[br]venting about this to a friend. 0:06:09.873,0:06:13.411 I was like, "Gosh, you know,[br]this is horrible." 0:06:13.411,0:06:16.597 And she said, "You know, Trisha,[br]I really admire your passion, 0:06:16.597,0:06:19.422 but you've been talking about this[br]for the last 15 minutes, 0:06:19.422,0:06:21.261 as if you had just discovered it. 0:06:21.261,0:06:23.522 It's a huge problem,[br]but social media sites 0:06:23.522,0:06:25.992 are already doing stuff to stop this." 0:06:25.992,0:06:28.620 And I went, "Oh, yeah. You're right." 0:06:28.620,0:06:32.355 But I'd soon find that[br]what social media sites are doing 0:06:32.355,0:06:34.540 is really nothing. 0:06:34.540,0:06:38.284 Their mechanism[br]is a "stop, block, tell" method. 0:06:38.284,0:06:41.411 You stop what you're doing,[br]through the victim, 0:06:41.411,0:06:43.000 you block the cyberbully 0:06:43.000,0:06:45.377 and you immediately[br]go tell a parent or guardian. 0:06:45.377,0:06:47.072 It sounds pretty reasonable. 0:06:47.072,0:06:49.549 But here's what actually happens: 0:06:49.549,0:06:52.532 adolescents, we're kind of afraid[br]to tell people 0:06:52.532,0:06:54.387 that we're being cyberbullied. 0:06:54.387,0:06:57.094 Research shows that nine out of ten times 0:06:57.094,0:07:00.476 victims don't tell anyone[br]that they're being cyberbullied. 0:07:00.476,0:07:02.810 What's more,[br]why are we putting the burden 0:07:02.810,0:07:05.863 on the victim to block the cyberbully? 0:07:05.863,0:07:10.353 Why aren't we changing the behavior[br]in the actual cyberbully? 0:07:10.353,0:07:12.076 And it angered me. 0:07:12.076,0:07:15.389 There wasn't a single effective way[br]to stop cyberbullying, 0:07:15.389,0:07:17.350 and it was a silent pandemic 0:07:17.350,0:07:20.722 that was affecting[br]so many people around the world. 0:07:21.422,0:07:22.951 That's when I had an idea. 0:07:22.951,0:07:26.781 I know from my research[br]that adolescents don't think 0:07:27.541,0:07:29.835 before they do things, right? 0:07:29.835,0:07:34.338 So, what if they didn't think[br]before they type? 0:07:34.338,0:07:36.116 What if I gave them a chance 0:07:36.116,0:07:38.973 to think about what they were doing? 0:07:38.973,0:07:42.903 If an adolescent tried to post[br]an offensive message on social media, 0:07:42.903,0:07:46.226 if I went, "Whoa! Hold on. 0:07:46.226,0:07:49.649 You're about to post[br]an offensive message to someone. 0:07:49.649,0:07:51.785 That can really hurt them. 0:07:51.785,0:07:54.802 Are you sure you want[br]to post this message?", 0:07:54.802,0:07:57.254 would they still be as willing to do it? 0:07:57.254,0:08:00.376 I had no idea, [br]but I was ready to find out. 0:08:01.216,0:08:04.909 So that year, using my science[br]and technology skills, 0:08:04.909,0:08:07.109 I created two software systems. 0:08:07.109,0:08:09.926 And basically, they were able to compare 0:08:09.926,0:08:12.802 whether an alert that prompted adolescents 0:08:12.802,0:08:15.017 to think about what they were doing 0:08:15.017,0:08:18.884 actually decreased their willingness[br]to post offensive messages. 0:08:18.884,0:08:22.733 So, for four to six weeks,[br]I basically lived at my local library. 0:08:22.733,0:08:25.156 All the kids were always[br]giving me weird looks, 0:08:25.156,0:08:28.370 but, you know, in the end,[br]it was totally worth it. 0:08:28.370,0:08:32.869 I was able to get[br]1,500 valid trials of data. 0:08:32.869,0:08:35.214 And what did I find? 0:08:35.214,0:08:40.781 93% of the time when adolescents[br]receive an alert that says, 0:08:40.781,0:08:44.285 "Whoa! You're about[br]to post an offensive message", 0:08:44.285,0:08:47.070 they changed their mind. 0:08:47.070,0:08:51.058 I was able to decrease the willingness[br]to post offensive messages 0:08:51.058,0:08:56.858 from 71.4% to 4.6%. 0:08:56.858,0:09:00.469 (Cheers) (Applause) 0:09:04.771,0:09:06.361 Think about that. 0:09:06.361,0:09:10.162 My research proved[br]that rethink before you type, 0:09:10.162,0:09:12.371 rethink before you post, 0:09:12.371,0:09:15.244 rethink before the damage is done 0:09:15.244,0:09:19.096 is an effective long-term method[br]to stop cyberbullying, 0:09:19.096,0:09:22.046 at the source, before the damage is done. 0:09:22.046,0:09:26.491 So Rethink has become[br]insanely popular -- I'm glad to say. 0:09:26.491,0:09:29.579 Just a few weeks ago,[br]I was at the Google Science Fair 0:09:29.579,0:09:32.188 for my research.
