I Studied The Brains of Potential Terrorists. Here's What I Learned.
A far-right nationalist opened fire in a hookah bar in Hanau, Germany, last month killing nine people. That same week, New Jersey raised the threat-assessment level of white extremists to a higher level than ISIS'.
How do we protect ourselves against attacks from white nationalists?
In the above video, a cognitive scientist, Nafees Hamid, argues the answer lies in understanding the minds of radicalized Islamists.
He spent the past seven years studying supporters of groups like ISIS and Al Qaeda and convinced more than 70 of them to have their brains scanned in an MRI. The results of two experiments show that we may have more power than we think to prevent the next white-nationalist attack.
The federal social distancing guidelines the White House announced six weeks ago expired Thursday, and the U.S. is still firmly in the grip of a pandemic, with well over 1 million infected and more than 62,000 dead. Some states, like Georgia and Texas, are starting to relax stay-at-home orders, but none of them have met federal guidelines about having sustained a declining number of coronavirus infections for 14 days straight. Here's a look at where things stand. Aired on 4/30/2020. CNN's Brian Stelter examines life during the coronavirus pandemic and how people in positions of power are handling it. We bought five used phones, of varying conditions, to see what sort of quality you can get when you don't splash out on a flagship. Results were...mixed. WWE champion Drew McIntyre talks about being the star of Monday Night Raw and reminisces on his favorite memories from the historic show over the years. (2:48) McIntyre expresses his thoughts on becoming champion and being the face of the company, especially during the coronavirus pandemic. (4:36) McIntyre provides his opinion on UFC fighter Colby Covington having interest in the WWE, how he thinks he would fair in the ring and adds that he would be willing to fight Covington in real life. (9:41) McIntyre discusses interest in potentially fighting Tyson Fury, saying, he isn't focused on him at the moment and more looking forward to fighting other WWE superstars. (15:06) McIntyre talks about his history with playing video games as a kid and if he plays any now.
Terrorists rely on you and me and the way we speak about their crimes to increase the impact, the virtual blast radius, massively, from a small town to the whole nation. "Once again in America, we are waking up to horrifying news." "Mass shooting with casualties." "In El Paso, Texas, new details about the carnage at a Wal-Mart." The Shooting in El Paso, Texas, was one of several deadly attacks in the U.S. last year and beyond. We have a power and responsibility to save lives, but it means changing the way we talk in the aftermath of an attack. You see, I'm a cognitive scientist, and I've spent the last seven years interviewing radicalized people — members and supporters of groups like Al Qaeda and ISIS. My colleagues and I carried out a bunch of psychological tests, including the first-ever brain scans of radicalized people. We didn't find any evidence of mental illness, but what we did find were clues to what makes people willing to fight and die for their beliefs. To show you how, I need to tell you about these brain scans, and that means taking you here. [MUSIC PLAYING] This is where our fieldwork began, looking for young men between the ages of 18 and 40, all on the path to radicalization. And under the promise of anonymity, they agreed to step inside an MRI machine. I need to stop here for a second, because it's important that you know about what cognitive scientists call sacred values. We all have beliefs that we care so passionately about that we'd be willing to go to extreme lengths to defend them. Well, guess what? Jihadists also have sacred values, and they're willing to use violence to defend them. And white nationalists have sacred values, too. [MUSIC PLAYING] It starts with one of these. We put some of our participants, the less radicalized ones, into a virtual ballgame with three other players. They threw the ball to each other like this. After a couple of rounds, half the players were excluded from the game. The other players ignored them. And that's when we put them into the MRI scanner. We know from previous research that when people are processing their sacred values, this part of the brain right here is very active. And when our subjects were thinking about their sacred values, sure enough, it lit up. But after they were ejected from the ballgame, something weird happened. It lit up for non-sacred values, too. In other words, when they felt excluded, the list of things they're willing to fight and die for got longer. Of course, people don't commit terrorist attacks just because nobody plays ball with them. But our research shows that if someone is at the early stage of radicalization, excluding them can make them more willing to use violence. [MUSIC PLAYING] In the next study, we took 30 highly radicalized supporters of an Al Qaeda associate and showed them a scale like this. We asked them to rate their willingness to fight and die for a series of sacred values, and then we showed them where their peers-- other Muslims in the community — fell on the scale. And while they were doing this, we scanned their brains. We found that when our subjects were highly willing to use violence, this part of the brain was deactivated. And that's a problem, because it could mean that they're not as open to negotiation or persuasion. So how do we reopen this person's mind? Well, when we told our participants that their wider social group were not as willing to commit violence as they were, this part of the brain reactivated. And get this — they lowered their explicit willingness to fight and die for these values just to match their peers. The lesson here is that people can be turned away from violence if they believe that a wider social group disapproves. This is only the first glimpse into the minds of radicalized people, but I do think it tells us something important about the role we play in preventing terrorism. In the days after the El Paso shooting, I saw a lot of tweets like this — prominent figures saying Trump's base is white nationalist, or if you support Trump, you support terrorism. Now, I'm not saying you shouldn't call out racism, but in a case like this, blaming all conservatives risks making someone out there feel more excluded. And if they're at the early stages of radicalization, it could push them closer to violence. At the very least, it creates divisions in society, which is exactly what terrorists want to achieve. No. 1, don't blame whole groups. And if you see or hear friends, family or people you follow online talking that way, challenge them. And number two, seek out and amplify voices on the right who are condemning violence. I still remember this tweet from a Trump supporter urging him to make a statement about white nationalism. He said, "We have to tell them we do not want them to be part of us." Voices like this have the power to turn someone away from violence. We're not responsible for the actions of terrorists, but we all have the power to limit the blast radius of an atrocity and maybe even prevent the next one.
