0:00:00.931,0:00:05.889 Eight years ago, I was haunted[br]by an evil spirit. 0:00:05.889,0:00:10.510 I was 25 at the time, 0:00:10.510,0:00:13.794 and I was living in a tiny house[br]behind someone else's house 0:00:13.794,0:00:16.676 in Los Angeles. 0:00:16.676,0:00:19.967 It was this guest house.[br]It had kind of been dilapidated, 0:00:19.967,0:00:22.539 not taken care of for a long time, 0:00:22.539,0:00:25.924 and one night, I was sitting there 0:00:25.924,0:00:30.839 and I got this really spooky feeling, 0:00:30.839,0:00:33.880 kind of a feeling[br]like you're being watched, 0:00:33.880,0:00:36.417 but no one was there except my two dogs, 0:00:36.417,0:00:39.308 and they were just chewing their feet. 0:00:39.308,0:00:42.825 And I looked around.[br]No one was there. 0:00:42.825,0:00:47.571 And I thought, okay,[br]it's just my imagination. 0:00:47.571,0:00:50.205 But the feeling just kept getting worse, 0:00:50.205,0:00:55.520 and I started to feel[br]this pressure in my chest, 0:00:55.520,0:00:58.477 sort of like the feeling[br]when you get bad news, 0:00:58.477,0:01:01.812 but it started to sink lower and lower 0:01:01.812,0:01:04.321 and almost hurt. 0:01:04.321,0:01:06.271 And over the course of that week, 0:01:06.271,0:01:08.105 this feeling got worse and worse, 0:01:08.105,0:01:10.478 and I started to become convinced 0:01:10.478,0:01:12.742 that something was there 0:01:12.742,0:01:17.197 in my little guest house, haunting me. 0:01:17.197,0:01:21.342 And I started to hear these sounds, 0:01:21.342,0:01:23.618 this "whooosh," 0:01:23.618,0:01:25.105 kind of whisper, 0:01:25.105,0:01:28.604 like something passing through me. 0:01:28.604,0:01:31.731 And I called my best friend Claire, 0:01:31.731,0:01:34.015 and I said, 0:01:34.015,0:01:36.761 "I know this is gonna sound crazy, 0:01:36.761,0:01:39.170 but, um... 0:01:39.170,0:01:41.898 I think there's a ghost in my house. 0:01:41.898,0:01:44.129 I need to get rid of it." 0:01:44.129,0:01:45.908 And she said -- 0:01:45.908,0:01:48.413 she's very open-minded, and she said, 0:01:48.413,0:01:49.941 "I don't think you're crazy. 0:01:49.941,0:01:53.771 I think you just need[br]to do a cleansing ritual." 0:01:53.771,0:01:55.529 (Laughter) 0:01:55.529,0:01:57.967 "So get some sage and burn it, 0:01:57.967,0:02:03.538 and tell it to go away." 0:02:03.538,0:02:04.951 So I said, "Okay," 0:02:04.951,0:02:07.227 and I went and I bought sage, 0:02:07.227,0:02:08.962 and I had never done this before, 0:02:08.962,0:02:11.198 so I set the sage on fire, 0:02:11.198,0:02:15.443 waved it about, and said, "Go away! 0:02:15.443,0:02:18.065 "This is my house! I live here. 0:02:18.065,0:02:20.808 You don't live here!" 0:02:20.808,0:02:24.065 But the feeling stayed.[br]Nothing got better. 0:02:24.065,0:02:27.412 And then I started to think,[br]okay, well now this thing's 0:02:27.412,0:02:29.179 probably just laughing at me, 0:02:29.179,0:02:31.630 because it hasn't left, 0:02:31.630,0:02:34.615 and I probably just look like[br]this impotent, powerless thing 0:02:34.615,0:02:36.874 that couldn't get it to go away. 0:02:36.874,0:02:40.823 And so every day I'd come home 0:02:40.823,0:02:44.725 and you guys, this feeling got so bad 0:02:44.725,0:02:48.032 that -- I mean, I'm laughing at it now --[br]but I would sit there in bed 0:02:48.032,0:02:51.239 and I would cry every night. 0:02:51.239,0:02:56.561 And the feeling on my chest[br]got worse and worse. 0:02:56.561,0:02:59.576 It was physically painful. 0:02:59.576,0:03:02.389 And I even went to a psychiatrist 0:03:02.389,0:03:05.840 and tried to get her[br]to prescribe me medicine, 0:03:05.840,0:03:10.902 and she wouldn't just because[br]I don't have schizophrenia, okay. 0:03:10.902,0:03:12.609 (Laughter) 0:03:12.609,0:03:18.086 So finally I got on the Internet, 0:03:18.086,0:03:20.902 and I googled hauntings. 0:03:20.902,0:03:23.871 And I came upon this forum[br]of ghost-hunters, 0:03:23.871,0:03:26.227 but these were a special[br]kind of ghost hunters. 0:03:26.227,0:03:27.952 They were skeptics. 0:03:27.952,0:03:30.521 And so they believed that every case 0:03:30.521,0:03:33.389 of ghosts that they[br]had investigated so far 0:03:33.389,0:03:35.588 had been explained away by science. 0:03:35.588,0:03:37.715 And I was like, "Okay, smart guys, 0:03:37.715,0:03:39.642 this is what's happening to me, 0:03:39.642,0:03:43.538 and if you have an explanation for me,[br]I would love to hear it." 0:03:43.538,0:03:46.084 And one of them said, 0:03:46.084,0:03:47.526 "Okay. 0:03:47.526,0:03:51.636 Um, have you heard of[br]carbon monoxide poisoning?" 0:03:51.636,0:03:57.516 And I said, "Yeah. 0:03:57.516,0:04:00.734 Like, gas poisoning?" 0:04:00.734,0:04:03.737 So carbon monoxide poisoning[br]is when you have a gas leak 0:04:03.737,0:04:05.318 leaking into your home, 0:04:05.318,0:04:06.826 and I looked it up, 0:04:06.826,0:04:10.793 and the symptoms[br]of carbon monoxide poisoning 0:04:10.793,0:04:14.210 include a pressure on your chest, 0:04:14.210,0:04:17.203 auditory hallucinations -- 0:04:17.203,0:04:18.797 whoosh -- 0:04:18.797,0:04:23.678 and an unexplained feeling of dread. 0:04:23.678,0:04:26.257 So that night, I called the gas company. 0:04:26.257,0:04:28.098 I said, "I have an emergency. 0:04:28.098,0:04:30.165 I need you to come out. 0:04:30.165,0:04:32.850 I don't want to get into the story now,[br]but I need you to come out." 0:04:32.850,0:04:34.597 (Laughter) 0:04:34.597,0:04:37.408 They came out. I said,[br]"I suspect a gas leak." 0:04:37.408,0:04:39.738 They brought their[br]carbon monoxide detector, 0:04:39.738,0:04:41.803 and the man said, 0:04:41.803,0:04:44.911 "It's a really good thing[br]that you called us tonight, 0:04:44.911,0:04:49.842 because you could[br]have been dead very soon." 0:04:49.842,0:04:54.647 Thirty-seven percent of Americans[br]believe in haunted houses, 0:04:54.647,0:04:59.194 and I wonder how many of them[br]have been in one 0:04:59.194,0:05:03.599 and how many of them[br]have been in danger. 0:05:03.599,0:05:07.083 So that haunting story 0:05:07.083,0:05:09.540 has led me to my job. 0:05:09.540,0:05:12.462 I'm an investigator, and I'm[br]an investigator in two senses. 0:05:12.462,0:05:15.458 I'm an investigative journalist,[br]and I'm also an investigator 0:05:15.458,0:05:19.389 of the claims of the paranormal[br]and claims of the spiritual. 0:05:19.389,0:05:20.920 And that means a few things. 0:05:20.920,0:05:24.791 Sometimes that means that I'm[br]pretending to need an exorcism 0:05:24.791,0:05:28.892 so I can get -- yes, that's right! --[br]so I can go to an exorcist 0:05:28.892,0:05:33.010 and see if he's using gimmicks[br]or psychological tricks 0:05:33.010,0:05:36.004 to try to convince someone[br]that they're possessed. 0:05:36.004,0:05:38.869 Sometimes that means[br]I'm going undercover in a fringe group 0:05:38.869,0:05:43.039 which I report on[br]for a podcast that I co-host. 0:05:43.039,0:05:47.565 And I've done over 70 investigations[br]like this with my co-host, Ross, 0:05:47.565,0:05:49.804 and I would love to tell you 0:05:49.804,0:05:52.743 that nine times out of 10, science wins, 0:05:52.743,0:05:55.477 saves the day, it's all explained. 0:05:55.477,0:05:58.232 That's not true. The truth is, 0:05:58.232,0:06:02.696 10 times out of 10, science wins,[br]it saves the day. 0:06:02.696,0:06:06.464 (Applause) 0:06:08.027,0:06:17.732 And that doesn't mean there's[br]no such thing as a mystery. 0:06:17.732,0:06:19.367 Of course there are mysteries, 0:06:19.367,0:06:21.815 but a mystery is a mystery. 0:06:21.815,0:06:23.865 It is not a ghost. 0:06:23.865,0:06:28.247 Now, I believe there are[br]two kinds of truth, 0:06:28.247,0:06:32.543 and it's taken me a while to get[br]to this place, but I think this is right, 0:06:32.543,0:06:33.650 so here me out. 0:06:33.650,0:06:36.953 I think there is outer truth[br]and there's inner truth. 0:06:36.953,0:06:39.782 So if you say to me, 0:06:39.782,0:06:42.889 "There was a man named Jesus[br]and he once existed," 0:06:42.889,0:06:44.388 that's outer truth. Right? 0:06:44.388,0:06:46.802 And we can go and we can look[br]at the historical record. 0:06:46.802,0:06:49.419 We can determine whether[br]that seems to be true. 0:06:49.419,0:06:51.982 And I would argue,[br]it does seem to be true. 0:06:51.982,0:06:56.247 If you say, "Jesus rose from the dead," 0:06:56.247,0:06:57.817 ooh, trickier. 0:06:57.817,0:07:00.135 (Laughter) 0:07:00.135,0:07:07.377 I would say that's an outer truth claim, 0:07:07.377,0:07:09.466 because he physically rose or he didn't. 0:07:09.466,0:07:12.216 I'm not going to get into[br]whether he rose or he didn't, 0:07:12.216,0:07:14.318 but I would say that's[br]an outer truth claim. 0:07:14.318,0:07:16.162 It happened or it didn't happen. 0:07:16.162,0:07:17.690 But if you say, 0:07:17.690,0:07:19.718 "I don't care whether[br]he rose from the dead. 0:07:19.718,0:07:24.603 It's symbolically important to me,[br]and that metaphor is so meaningful, 0:07:24.603,0:07:28.060 so purposeful to me, and I'm[br]not going to try to persuade you of it," 0:07:28.060,0:07:30.593 now you've moved it from[br]outer truth to inner truth, 0:07:30.593,0:07:32.310 from science to art. 0:07:32.310,0:07:35.288 And I think we have a tendency[br]to not be clear about this, 0:07:35.288,0:07:38.643 to try to move our inner truths[br]to outer truths, 0:07:38.643,0:07:41.651 or to not be fair about it to each other, 0:07:41.651,0:07:44.014 and when people are telling us[br]their inner truths, 0:07:44.014,0:07:45.750 to try to make them defend them 0:07:45.750,0:07:47.861 by outer truth standards. 0:07:47.861,0:07:49.906 So I'm talking here about outer truth, 0:07:49.906,0:07:51.457 about objective things, 0:07:51.457,0:07:55.459 and there was an objective reality 0:07:55.459,0:07:56.924 in my haunted house. Right? 0:07:56.924,0:07:58.998 Now that I've told you about the gas leak, 0:07:58.998,0:08:00.917 I doubt a single person here[br]would be like, 0:08:00.917,0:08:02.979 "I still think there was a ghost too," 0:08:02.979,0:08:06.400 because as soon as we have[br]these scientific explanations, 0:08:06.400,0:08:08.672 we know to give up the ghost. 0:08:08.672,0:08:12.696 We use these things as stopgaps[br]for things that we can't explain. 0:08:12.696,0:08:14.676 We don't believe them because of evidence. 0:08:14.676,0:08:17.779 We believe them because[br]of a lack of evidence. 0:08:17.779,0:08:20.166 So there was a group in Los Angeles 0:08:20.166,0:08:23.213 called the Independent[br]Investigations Group, 0:08:23.213,0:08:24.638 or the IIG, 0:08:24.638,0:08:26.641 and they do great work. 0:08:26.641,0:08:29.233 They'll give a 10,000 dollar prize 0:08:29.233,0:08:32.132 to anyone who can show 0:08:32.132,0:08:33.834 under scientific conditions 0:08:33.834,0:08:36.336 that they have a paranormal ability. 0:08:36.336,0:08:38.015 No one's done it yet, 0:08:38.015,0:08:42.975 but they've had a couple people[br]who claim that they were clairaudients, 0:08:42.975,0:08:46.881 which means that they can[br]hear voices either from the great beyond 0:08:46.881,0:08:48.735 or they can read minds, 0:08:48.735,0:08:50.245 and they had one person 0:08:50.245,0:08:51.761 who was very sincere 0:08:51.761,0:08:54.567 who believed that he could read minds. 0:08:54.567,0:08:57.449 And a lot of these people -- 0:08:57.449,0:09:00.313 (Laughter) -- 0:09:00.313,0:09:03.350 That wasn't a laugh line, but okay. 0:09:03.350,0:09:06.394 A lot of these people 0:09:06.394,0:09:08.197 really are sincere, 0:09:08.197,0:09:10.161 and I believe this guy was. 0:09:10.161,0:09:12.233 He really thought he had this power. 0:09:12.233,0:09:15.745 So they set up a test with him, 0:09:15.745,0:09:18.243 and this is the way it always works. 0:09:18.243,0:09:20.563 The group says, "Okay, we have a protocol, 0:09:20.563,0:09:23.209 we have a way to scientifically test this.[br]Do you agree with it?" 0:09:23.209,0:09:25.649 The person says yes. Then they test it. 0:09:25.649,0:09:27.679 It's very important that both sides agree. 0:09:27.679,0:09:29.132 They did that. 0:09:29.132,0:09:30.278 They tested him. 0:09:30.278,0:09:32.695 They said, "Okay, you know what? 0:09:32.695,0:09:35.902 You weren't able to predict[br]what Lisa was thinking. 0:09:35.902,0:09:38.614 It matched up about[br]the same as chance. 0:09:38.614,0:09:40.564 Looks like you don't have the power." 0:09:40.564,0:09:42.437 And that gave them the opportunity 0:09:42.437,0:09:44.913 to compassionately sit down with him 0:09:44.913,0:09:47.555 and have a very difficult discussion, 0:09:47.555,0:09:49.257 which basically amounted to, 0:09:49.257,0:09:52.750 "Hey, we know you're sincere, 0:09:52.750,0:09:54.430 and what that means is, 0:09:54.430,0:09:56.732 you do hear something in your head." 0:09:56.732,0:09:59.494 And that's a tough thing to face. 0:09:59.494,0:10:03.846 (Laughter) (Applause) 0:10:03.846,0:10:10.904 But that day, that guy got to[br]make the very difficult decision, 0:10:10.904,0:10:14.800 but really the life-changing decision 0:10:14.800,0:10:18.997 about whether to go get help. 0:10:19.657,0:10:23.971 But that really could be[br]the first day of the rest of your life, 0:10:23.971,0:10:28.255 because when we challenge these beliefs, 0:10:28.255,0:10:33.322 we're actually helping people[br]to make these connections 0:10:33.322,0:10:38.322 that maybe before seemed like[br]otherworldly explanations, 0:10:38.322,0:10:40.467 help draw us into reality 0:10:40.467,0:10:44.221 and maybe change our lives for the better. 0:10:45.487,0:10:49.287 Now, on the other hand, 0:10:49.287,0:10:51.896 maybe on time it'll turn out to be true. 0:10:51.896,0:10:53.942 Maybe we'll find out there are ghosts, 0:10:53.942,0:10:56.248 and holy shit, it will be the best thing! 0:10:56.248,0:10:58.888 And every time I do[br]one of these investigations, 0:10:58.888,0:11:00.717 I still get so excited, 0:11:00.717,0:11:02.803 and I'm like 75 into them, 0:11:02.803,0:11:06.903 and still I swear on number 76,[br]I'm going to be like, this is the one. 0:11:06.903,0:11:08.131 (Laughter) 0:11:08.131,0:11:10.526 Maybe I'm just eternally optimistic, 0:11:10.526,0:11:12.603 but I hope I never lose this hope, 0:11:12.603,0:11:16.686 and I invite you to take[br]this same attitude 0:11:16.686,0:11:19.285 when people share[br]their outer beliefs with you. 0:11:19.285,0:11:21.472 When talking about testable claims, 0:11:21.472,0:11:25.347 respect them enough to ask[br]these good questions. 0:11:25.347,0:11:28.340 Challenge and see how you can[br]examine them together, 0:11:28.340,0:11:32.532 because there's this idea[br]that you can't respect a belief 0:11:32.532,0:11:35.157 and still challenge it,[br]but that's not true. 0:11:35.157,0:11:37.927 When we jiggle the lock,[br]when we test the claim, 0:11:37.927,0:11:40.182 we're saying, okay, I respect you, 0:11:40.182,0:11:41.866 I'm listening to what you're saying, 0:11:41.866,0:11:43.839 I'm going to test it out with you. 0:11:43.839,0:11:46.703 Like, we've all had that experience[br]where you're telling someone something, 0:11:46.703,0:11:49.686 and they're like, "Oh,[br]that's really interesting, yeah." 0:11:49.686,0:11:52.213 You know you're being had, 0:11:52.213,0:11:56.163 but when someone says, "Really?
