WEBVTT 00:00:09.444 --> 00:00:11.211 All right. 00:00:12.091 --> 00:00:15.726 So, my name's Carl Fisher and I'm a forensic psychiatrist. 00:00:15.726 --> 00:00:18.206 That means I work in the kind of psychiatry 00:00:18.206 --> 00:00:19.760 that deals with the court system, 00:00:19.760 --> 00:00:22.425 the kind of evidence people bring about neuroscience, 00:00:22.425 --> 00:00:25.019 mental health, psychiatric diagnosis 00:00:25.019 --> 00:00:28.299 and the way that impacts the way we think about law. 00:00:28.299 --> 00:00:31.169 So, today I wanted to talk about punishment, 00:00:31.169 --> 00:00:33.315 because one thing I've become interested in 00:00:33.315 --> 00:00:37.011 is, as a new trend, people are actually using neuroscience itself -- 00:00:37.011 --> 00:00:40.613 brain scans, brain images -- in the court to make certain arguments 00:00:40.613 --> 00:00:42.932 about the way we punish individuals, 00:00:42.932 --> 00:00:46.036 or even about the way our legal system should function overall. 00:00:46.036 --> 00:00:47.901 In its most simple form, 00:00:47.901 --> 00:00:52.110 this takes the shape, "It wasn't me, it was my brain." 00:00:52.110 --> 00:00:55.165 So, it sounds a little sketchy when you see it at first, right? 00:00:55.165 --> 00:00:57.273 It doesn't make total intuitive sense. 00:00:57.273 --> 00:00:59.546 If my brain is the thing that produces my mind, 00:00:59.546 --> 00:01:01.851 if that's where my experiences, and my thoughts, 00:01:01.851 --> 00:01:04.219 and all of my feelings and motivations are stored, 00:01:04.219 --> 00:01:06.343 then how could a reference to my brain 00:01:06.343 --> 00:01:09.640 mean that I'm not responsible for a crime that I commit? 00:01:09.640 --> 00:01:11.336 Let me tell you a story 00:01:11.336 --> 00:01:13.268 that might help to set the scene 00:01:13.268 --> 00:01:16.441 and understand some of the issues here. 00:01:16.441 --> 00:01:18.044 So, this is a real story. 00:01:18.044 --> 00:01:20.633 It happened not too long ago in Virginia, 00:01:20.633 --> 00:01:26.312 where this mild-mannered, middle aged guy, early 40's, stable life, 00:01:26.312 --> 00:01:28.253 had a wife, kids, picket fence. 00:01:28.253 --> 00:01:30.630 Then, all of a sudden, he develops this interest -- 00:01:30.630 --> 00:01:32.203 brand-new, he hides it at first -- 00:01:32.203 --> 00:01:33.880 in child pornography. 00:01:33.880 --> 00:01:35.966 He starts collecting it, 00:01:35.966 --> 00:01:38.111 he starts secretly gathering it. 00:01:38.111 --> 00:01:39.702 And then, it starts to get worse: 00:01:39.702 --> 00:01:41.665 he gets interested in massage parlors. 00:01:41.665 --> 00:01:43.971 He starts propositioning people for sex. 00:01:43.971 --> 00:01:45.781 And then, eventually, saddly, 00:01:45.781 --> 00:01:47.929 his wife catches him making sexual advances 00:01:47.929 --> 00:01:49.610 toward his twelve-year-old kid. 00:01:49.610 --> 00:01:51.838 So, he's brought before court 00:01:51.838 --> 00:01:54.779 and he's convicted of child molestation. 00:01:54.779 --> 00:01:57.384 And, as a first-time offender, he gets the opportunity 00:01:57.384 --> 00:01:58.999 to engage in a treatment program. 00:01:58.999 --> 00:02:00.807 So, he goes to treatment groups, 00:02:00.807 --> 00:02:02.619 he gets some sort of therapy, 00:02:02.619 --> 00:02:05.530 but he fails miserably, because he can't stop propositioning 00:02:05.530 --> 00:02:07.245 the other people in the groups. 00:02:07.245 --> 00:02:09.162 So, he's scheduled to go back to court, 00:02:09.162 --> 00:02:10.708 and this time he's getting sentenced. 00:02:10.708 --> 00:02:13.758 This time, everyone knows that he's going to get some jail time. 00:02:13.758 --> 00:02:16.322 The night before the court, 00:02:16.322 --> 00:02:17.959 he goes to the emergency room, 00:02:17.959 --> 00:02:20.574 and he's complaining of the worst headache of his life. 00:02:20.574 --> 00:02:22.307 Once people get the full story, they think, 00:02:22.307 --> 00:02:25.768 "Hey, maybe this is... he's trying to get out of his punishment. 00:02:25.768 --> 00:02:29.128 This doesn't seem like it really hangs together." 00:02:29.128 --> 00:02:32.458 But they give the guy the benefit of the doubt 00:02:32.458 --> 00:02:34.786 and they do a brain scan. 00:02:34.786 --> 00:02:38.383 And they find this. It's a huge tumor in his frontal lobe. 00:02:38.383 --> 00:02:39.867 Luckily for him, it's a benign tumor. 00:02:39.867 --> 00:02:41.340 It's actually just a bone tumor 00:02:41.340 --> 00:02:43.711 that's pressing on his orbital frontal cortex, 00:02:43.711 --> 00:02:46.357 which is the part of the brain that people think governs 00:02:46.357 --> 00:02:48.833 social behavior and social regulation. 00:02:48.833 --> 00:02:51.984 So, they remove the tumor, the guy does all right, 00:02:51.984 --> 00:02:53.882 he goes back to the treatment court 00:02:53.882 --> 00:02:56.141 and he passes with flying colors. 00:02:56.141 --> 00:02:58.622 He's back to his normal mild-mannered self. 00:02:58.622 --> 00:02:59.992 Then, a couple years later, 00:02:59.992 --> 00:03:01.504 he starts to develop these urges again, 00:03:01.504 --> 00:03:03.867 but, thankfully, he's on the lookout for it. 00:03:03.867 --> 00:03:06.551 He goes back. Sure enough, the tumor is back. 00:03:06.551 --> 00:03:09.242 It's removed again and he's fine. 00:03:09.242 --> 00:03:11.767 And, as far as we know, to this day, 00:03:11.767 --> 00:03:13.364 no more problems. 00:03:13.364 --> 00:03:16.129 So, my point here is that this notion, 00:03:16.129 --> 00:03:19.804 "It wasn't me, it was my brain" sounds a little odd at first, 00:03:19.804 --> 00:03:22.540 but maybe there are certain cases where it actually makes sense. 00:03:22.540 --> 00:03:25.293 Maybe there are certain cases where we have to investigate 00:03:25.293 --> 00:03:27.042 a little further. 00:03:27.042 --> 00:03:31.447 This is some research from some Duke University law researchers, 00:03:31.447 --> 00:03:33.179 looking at court cases, 00:03:33.179 --> 00:03:35.378 and how often they say actual neuroscience, 00:03:35.378 --> 00:03:38.512 how often somebody produces brain imaging 00:03:38.512 --> 00:03:39.963 or brain scanning evidence. 00:03:39.963 --> 00:03:43.271 And so, in 2005, we already had about a hundred cases 00:03:43.271 --> 00:03:45.187 where people were doing this. 00:03:45.187 --> 00:03:47.919 This is growing exponentially, though. 00:03:47.919 --> 00:03:50.618 So, in just seven years, 00:03:50.618 --> 00:03:52.307 more than double the number of cases 00:03:52.307 --> 00:03:53.655 have been produced in court. 00:03:53.655 --> 00:03:56.175 So, this is happening, it's already getting traction. 00:03:56.175 --> 00:03:59.255 And these are only the court cases that are reported in opinions. 00:03:59.255 --> 00:04:00.927 There's probably more going on 00:04:00.927 --> 00:04:02.835 in the everyday pratice of courts. 00:04:02.835 --> 00:04:05.560 So, in most cases, this has to do with mitigation, 00:04:05.560 --> 00:04:07.768 it has to do with lowering someone's sentence, 00:04:07.768 --> 00:04:09.981 not getting them off entirely. 00:04:09.981 --> 00:04:13.060 So, I'm going to give a couple of examples about how this works. 00:04:13.060 --> 00:04:14.950 So, in the United States, 00:04:14.950 --> 00:04:18.147 there's a famous case of a serial killer called Brian Dugan. 00:04:18.147 --> 00:04:20.383 And I won't get into the gruesome details, 00:04:20.383 --> 00:04:23.005 but the point is that there's no doubt about his guilt. 00:04:23.005 --> 00:04:25.115 It was very clear that this man was guilty. 00:04:25.115 --> 00:04:27.612 So, the prosecution was going for the death penalty. 00:04:27.612 --> 00:04:30.754 The defense lawyers decided that the strategy would be, 00:04:30.754 --> 00:04:32.660 "Let's get an expert in brain imaging, 00:04:32.660 --> 00:04:34.547 scan his brain and put up some cartoons 00:04:34.547 --> 00:04:36.040 to make a very novel argument." 00:04:36.040 --> 00:04:38.616 It was the first time it happened in American courts. 00:04:38.616 --> 00:04:41.128 And they argued that Mr. Dugan had psychopathy. 00:04:41.128 --> 00:04:43.518 Psychopathy is a special medical condition. 00:04:43.518 --> 00:04:46.009 As indicated by his brain scans, 00:04:46.009 --> 00:04:49.479 he can't engage in a normal sort of impulse regulation, 00:04:49.479 --> 00:04:51.352 he can't govern his behavior. 00:04:51.352 --> 00:04:54.304 There's just something wrong with his brain, it's not him. 00:04:54.304 --> 00:04:58.430 And it's always hard to say exactly what causes a particular event, 00:04:58.430 --> 00:05:00.877 what causes the jury to make a decision, 00:05:00.877 --> 00:05:04.328 but, in this case, they actually voided the death penalty. 00:05:04.328 --> 00:05:07.056 So, for an even more stark example, 00:05:07.056 --> 00:05:08.558 let's go over to Italy. 00:05:08.558 --> 00:05:12.790 There is a woman, Stefania Albertani, just a couple of years ago, 00:05:12.790 --> 00:05:15.627 who killed her sister, attempted to murder her parents, 00:05:15.627 --> 00:05:16.944 and got a life sentence. 00:05:16.944 --> 00:05:18.687 But then, the defense got the opportunity 00:05:18.687 --> 00:05:20.188 to present some more evidence. 00:05:20.188 --> 00:05:22.279 They presented some evidence about brain imaging 00:05:22.279 --> 00:05:24.512 and they made the argument that the brain areas 00:05:24.512 --> 00:05:27.301 that govern impulsivity were disfunctional in her. 00:05:27.301 --> 00:05:31.702 So, they managed to reduce her life sentence down to tweny years. 00:05:31.702 --> 00:05:33.773 So, we're already seeing some evidence 00:05:33.773 --> 00:05:35.118 that this stuff is working, 00:05:35.118 --> 00:05:37.241 it's getting traction, it's being used, 00:05:37.241 --> 00:05:39.204 and, in particular cases, brain imaging 00:05:39.204 --> 00:05:42.349 is actually managing to lower particular people's sentences. 00:05:42.349 --> 00:05:45.243 But does it have any impact on the court system at all? 00:05:45.243 --> 00:05:48.529 Can it change the way that we punish people overall? 00:05:48.529 --> 00:05:51.051 So, to answer that question, 00:05:51.051 --> 00:05:53.670 I'm going to turn to the US juvenile justice systems. 00:05:53.670 --> 00:05:57.005 So, if you've had any familiarity or any encounters with this system, 00:05:57.005 --> 00:05:59.104 you'll know that the US can be pretty harsh 00:05:59.104 --> 00:06:01.042 when it comes to punishing kids. 00:06:01.042 --> 00:06:03.531 Until recently, kids could get the death penalty, 00:06:03.531 --> 00:06:05.897 they could be sentenced to life without parole. 00:06:05.897 --> 00:06:08.791 But there's been a series of recent supreme court cases 00:06:08.791 --> 00:06:10.652 that challenged that notion. 00:06:10.652 --> 00:06:14.498 The first was in 2005, Roper versus Simmons, 00:06:14.498 --> 00:06:17.068 and this was a case that challenged the death penalty 00:06:17.068 --> 00:06:19.054 for sixteen and seventeen-year-olds. 00:06:19.054 --> 00:06:22.064 And the majority opinion ruled that that was unconstitutional, 00:06:22.064 --> 00:06:25.247 that you couldn't give the death penalty to juveniles. 00:06:25.247 --> 00:06:27.232 And it's an especially notable case, 00:06:27.232 --> 00:06:28.708 because, for the first time, 00:06:28.708 --> 00:06:31.383 the supreme court actually cited neuroscience data. 00:06:31.383 --> 00:06:34.645 They said not only are adolescents not fully mature, 00:06:34.645 --> 00:06:37.546 that brain imaging and brain scaning actually shows us that. 00:06:37.546 --> 00:06:40.855 They show that the brain is still developing and evolving at that age. 00:06:40.855 --> 00:06:42.811 And that's part of their justification 00:06:42.811 --> 00:06:45.121 for why this is unconstitutional. 00:06:45.121 --> 00:06:47.891 Moving ahead to more recent cases, 00:06:47.891 --> 00:06:49.951 two more cases just very recently 00:06:49.951 --> 00:06:53.027 challenged the possibility of life without parole for juveniles, 00:06:53.027 --> 00:06:54.523 again found unconstitutional. 00:06:54.523 --> 00:06:58.533 But what's notable is, as we go in progression, case to case, 00:06:58.533 --> 00:07:00.047 the amount of the court opinion 00:07:00.047 --> 00:07:02.375 that's devoted to neuroscience is increasing. 00:07:02.375 --> 00:07:04.673 What was just a footnote in Roper versus Simmons 00:07:04.673 --> 00:07:06.117 is now a whole section 00:07:06.117 --> 00:07:08.721 in the most recent case of Miller versus Alabama. 00:07:08.721 --> 00:07:11.360 So, we see that, in the highest court of the US, 00:07:11.360 --> 00:07:13.464 there's more and more focus on neuroscience. 00:07:13.464 --> 00:07:16.092 It's getting more traction. 00:07:16.092 --> 00:07:19.137 So, this has led some folks, especially in Academia, 00:07:19.137 --> 00:07:21.053 to make some claims about how neuroscience 00:07:21.053 --> 00:07:23.840 should change the way we think about neuroscience overall, 00:07:23.840 --> 00:07:26.661 about how our punishment practices in the US should be changed. 00:07:26.661 --> 00:07:28.300 So, this is David Eagleman. 00:07:28.300 --> 00:07:30.316 He's a neuroscientist down at Baylor 00:07:30.316 --> 00:07:32.186 and he's got a good example. 00:07:32.186 --> 00:07:33.735 He says that criminal activity 00:07:33.735 --> 00:07:35.993 should be taken as evidence of brain abnormality. 00:07:35.993 --> 00:07:37.583 We shouldn't see it as bad behavior. 00:07:37.583 --> 00:07:40.393 We should just see it as some sort of biological disfunction, 00:07:40.393 --> 00:07:43.774 and, furthermore, that we should tailor punishment to individuals, 00:07:43.774 --> 00:07:45.959 it should just be about rehabilitation, 00:07:45.959 --> 00:07:48.193 it should just be about treatment. 00:07:48.193 --> 00:07:50.916 This is becoming a very fashionable idea 00:07:50.916 --> 00:07:53.077 throughout all the halls of Academia. 00:07:53.077 --> 00:07:55.932 Philosophers, law professors, neuroscientists 00:07:55.932 --> 00:07:59.692 are now looking to neuroscience to provide a justification. 00:07:59.692 --> 00:08:02.265 Punishment in the United States right now, they say, 00:08:02.265 --> 00:08:04.762 is too retribution-based. 00:08:04.762 --> 00:08:07.065 We're trying to give people their just deserts. 00:08:07.065 --> 00:08:10.781 What we should be doing is be focusing on rehabilitation, 00:08:10.781 --> 00:08:13.015 about helping people. 00:08:13.015 --> 00:08:15.397 So, it sounds like an attractive concept, right, 00:08:15.397 --> 00:08:18.882 to have a more humane and more just punishment system, 00:08:18.882 --> 00:08:21.520 but I think we need to look to history for some lessons 00:08:21.520 --> 00:08:23.271 about how this might play out. 00:08:23.271 --> 00:08:28.366 So, this is a picture of the Alcatraz jazz band, in the 1950's. 00:08:28.366 --> 00:08:30.682 So, back around this time, the 1950's and 60's, 00:08:30.682 --> 00:08:35.026 in US punishment philosophy and US punishment justifications, NOTE Paragraph 00:08:35.026 --> 00:08:37.594 people were very invested in the rehabilitation model. 00:08:37.594 --> 00:08:41.059 There was a lot of focus on addressing the root causes of crime. 00:08:41.059 --> 00:08:44.578 Maybe if we can provide people with useful opportunities, 00:08:44.578 --> 00:08:48.036 ways to develop themselves as people, we can prevent crime, 00:08:48.036 --> 00:08:49.890 and once people are released, 00:08:49.890 --> 00:08:53.680 we won't get the same rates of recidivism as we do normally. 00:08:53.680 --> 00:08:55.963 The problem with this was that it didn't work. 00:08:55.963 --> 00:08:59.461 The social reformers were overclaiming, overpromising, 00:08:59.461 --> 00:09:01.654 and then, when those results weren't realized, 00:09:01.654 --> 00:09:04.377 it set the stage for a backlash. 00:09:04.377 --> 00:09:06.352 So, by the 1980's, 00:09:06.352 --> 00:09:08.767 we have a totally different retoric. 00:09:08.767 --> 00:09:12.228 We have the war on crime, mandatory minimum sentences, 00:09:12.228 --> 00:09:14.713 determinative sentences that take more of the choice 00:09:14.713 --> 00:09:16.873 out of judges' hands. 00:09:16.873 --> 00:09:18.834 And what I'd like to suggest 00:09:18.834 --> 00:09:21.966 is that this is, in large part, due to a setup. 00:09:21.966 --> 00:09:25.480 The social reformers of the 50's and 60's, by overpromising, 00:09:25.480 --> 00:09:27.435 set the stage for this sort of backlash, 00:09:27.435 --> 00:09:29.066 when the pendulum swung back 00:09:29.066 --> 00:09:32.544 toward a more retribution-based punishment system. 00:09:32.544 --> 00:09:35.454 This is a graph of incarceration rates in the United States, 00:09:35.454 --> 00:09:36.832 as a function of population. 00:09:36.832 --> 00:09:38.732 So, it's just the proportion of people 00:09:38.732 --> 00:09:40.549 who are locked up at any given time. 00:09:40.549 --> 00:09:43.676 So, what we see here is, dating back to 1925, 00:09:43.676 --> 00:09:46.163 incarceration rates were relatively stable, 00:09:46.163 --> 00:09:48.213 including through the social reform era. 00:09:48.213 --> 00:09:51.720 But then, around this time, in the late 1970's, 1980's, 00:09:51.720 --> 00:09:54.819 where the tough-on-crime retoric starts to pick up speed, 00:09:54.819 --> 00:09:58.063 we see a massive increase in incarceration rates. 00:09:58.063 --> 00:10:02.231 And so, to bring us back to neuroscience, 00:10:02.231 --> 00:10:03.771 the story I want to tell 00:10:03.771 --> 00:10:06.720 is that it has implications for what we do 00:10:06.720 --> 00:10:08.374 with the science that we're using. 00:10:08.374 --> 00:10:10.109 To promote a treatment model sounds good, 00:10:10.109 --> 00:10:13.444 but we have to be careful about what scientific arguments we hitch 00:10:13.444 --> 00:10:15.780 on to our policy argument. 00:10:16.310 --> 00:10:19.333 Neuroscience might have a limited role in the court room. 00:10:19.333 --> 00:10:21.055 In cases where someone has a tumor, 00:10:21.055 --> 00:10:24.334 in cases where someone has a clearly identified abnormality, 00:10:24.334 --> 00:10:26.589 it might be useful to investigate further. 00:10:26.589 --> 00:10:29.198 But, even then, facts are just facts, and that's how science works. 00:10:29.198 --> 00:10:31.193 They give us the facts, but then, in the court of law, 00:10:31.193 --> 00:10:33.709 or in ethics or in any sort of value system, 00:10:33.709 --> 00:10:35.711 then we have to make the active step 00:10:35.711 --> 00:10:38.957 of making a determination about what actually matters. 00:10:38.957 --> 00:10:43.128 I'd like to suggest that the dangerous part of this trend 00:10:43.128 --> 00:10:46.987 is this notion: "It isn't us, it's our brains." 00:10:46.987 --> 00:10:50.219 To argue for a systemwide reform on the basis of neuroscience 00:10:50.219 --> 00:10:52.820 gets in a dangerous territory. 00:10:52.820 --> 00:10:57.171 We've already seen that making overpromises and making overclaims 00:10:57.171 --> 00:10:59.464 might set the stage for a pendular backlash, 00:10:59.464 --> 00:11:01.458 and you can imagine the same sort of data 00:11:01.458 --> 00:11:03.605 being used for the opposite argument: 00:11:03.605 --> 00:11:05.292 if someone's brain is broken 00:11:05.292 --> 00:11:07.571 or if their brain determines that they're a criminal, 00:11:07.571 --> 00:11:09.438 why not lock them up for longer? 00:11:09.438 --> 00:11:11.728 So, I think we have to be careful about these questions. 00:11:11.728 --> 00:11:13.321 There are a lot of questions that are worth asking 00:11:13.321 --> 00:11:14.762 about the US punishment system. 00:11:14.762 --> 00:11:16.888 My point is not to make a political point, 00:11:16.888 --> 00:11:19.894 but just whether we're interested in 00:11:19.894 --> 00:11:23.026 whether the US legal system is punishing people the right way, 00:11:23.026 --> 00:11:25.308 if our penal system is accomplishing the goals 00:11:25.308 --> 00:11:27.183 that it's set out to accomplish. 00:11:27.183 --> 00:11:29.046 These are questions worth asking. 00:11:29.046 --> 00:11:31.855 But we don't need to wait for neuroscience to tell us the answers. 00:11:31.855 --> 00:11:34.456 We don't need to hitch our arguments on to neuroscience. 00:11:34.456 --> 00:11:36.368 That's my talk. Thanks very much. 00:11:36.368 --> 00:11:39.432 (Applause)
