1. The Dangers of Safety

[0] What comes to mind risk -wise when I say the following things?

[1] Shark attacks.

[2] The biggest joke of all time.

[3] All right.

[4] Terrorist attacks.

[5] The biggest waste of time ever.

[6] This is Freakonomics Radio, a new podcast about the hidden side of everything.

[7] In this episode, what do NASCAR drivers Glenn Beck and the hit men of the NFL have in common?

[8] Here's your host, Stephen Dubner.

[9] How about the risk of just something almost everybody does every day, driving your car?

[10] Incredibly low.

[11] That if nothing were to kill you except driving your car and all you did was drive your car day and night, day and night, day and night, you'd expect to live for 250 years.

[12] Steve Levitt is the guy I write books with, Freakonomics and Super Freakonomics.

[13] He's a professor at the University of Chicago, and he looks like a professor, skinny, thick glass.

[14] comfortable shoes.

[15] No one's ever going to mistake him for a tough guy.

[16] But there aren't many things he's afraid of.

[17] You know why?

[18] Because he's a data guy who spent a lot of time figuring out what'll kill you and what won't.

[19] So he thinks most of our fears are vastly overrated.

[20] I think it's their survival instinct for one thing, right?

[21] You think about spiders and tigers and, you know, rhinos.

[22] I mean, things that we shouldn't be afraid of bugs.

[23] I mean, but we're terrified of them.

[24] But I think people are predisposed to be frightened of things.

[25] And in a world of media where we're now bombarded, I mean, I think kidnapping is a great example.

[26] People used to be kidnapped a lot more than they are today.

[27] But you wouldn't hear about the little blonde girl who's being kidnapped in Utah if you lived in Chicago or in New York.

[28] But now a little blonde girl gets kidnapped in its national news.

[29] The media promotes fears because people love to read about scary stuff, like horror movies.

[30] Who in their right mind, you know, if someone came from Mars would think that horror movies would be this incredibly successful genre where people would try to scare themselves a lot.

[31] People are afraid of needles.

[32] Don't go to the hospital and have the needles stuck in them just so they can get the fear.

[33] It's strange how people's brains works that way.

[34] You know what's even stranger?

[35] Football.

[36] Instead of running away from scary things that are highly improbable, football players run into each other on purpose.

[37] really hard, without fear.

[38] I'm Terrence Newman of the Dallas Cowboys.

[39] Terrence Newman is one of the hardest hitters in the NFL.

[40] You might think he's a big guy, but he's not.

[41] He's about 5 -11, 190 pounds.

[42] That said, he is a rock -hard dude, or, as he puts it, swole, as in swollen with muscle.

[43] On the field, Newman is famous for launching his body like a missile.

[44] If you're a cornerback, what's your favorite thing to do?

[45] Favorite thing is obviously get interceptions and running back for touchdowns.

[46] All right.

[47] Second favorite thing then.

[48] Second favorite thing is blowing up receivers.

[49] All right.

[50] And for those who don't know what blowing up a receiver means, what does that mean exactly?

[51] Or a running back, but it just means catching them with a good solid hit and basically decliner.

[52] When you hit them and they go backwards and you go running over the top of them and celebrating and going crazy and all that stuff.

[53] Robert C. Cantu, C -A -N -T -U.

[54] And how old are you?

[55] Older than you might think, 71.

[56] Robert Cantu is a professor of neurosurgery at Boston University, and he specializes in the study of traumatic encephalopathy, or major blows to the brain.

[57] So let's talk about the NFL.

[58] I love the NFL.

[59] You love the NFL?

[60] Yes.

[61] The build -up is over.

[62] Dr. Cantu and I are not alone.

[63] alone.

[64] The Super Bowl has become a national holiday.

[65] More people watch it on TV than any other show.

[66] Millions of kids grow up with the dream of playing in the NFL.

[67] My own son included.

[68] He's nine years old.

[69] Four foot two.

[70] Fifty -four pounds.

[71] He ain't exactly swole.

[72] When is the last time that you know of that there's been an on -the -field death in football?

[73] There had been on -the -field deaths in football every single year since 1931.

[74] with the exception of 1990.

[75] Last year, there were five on -field deaths.

[76] This year, there had been two.

[77] Both all five last year and both this year were due to brain injuries.

[78] So fatalities still occur, but they occur at relatively low rates compared with 36, 37, 38 deaths a year that were seen 40 years ago.

[79] Four or five deaths?

[80] That's about the same number of people killed every year around the world in shark attacks.

[81] But who's afraid of football?

[82] Cantu says most football deaths occur in high school and college.

[83] There hasn't been a single on -field death in the NFL.

[84] I'm guessing if there was.

[85] If a cornerback like Terence Newman blew up a receiver like Chad Ochosinko on national TV and he never got up again, people would be a lot more afraid of football than they are.

[86] I don't play with fear.

[87] I guess you get a little nervous about knowing your assignments or getting beat on certain things, but in terms of contact or anything like that, I'm not scared of any of that.

[88] Quentin Michael plays strong safety for the Philadelphia Eagles.

[89] He's roughly the same size as Terrence Newman.

[90] He, too, is known for hitting very, very hard.

[91] The hardest hit I ever had was actually this year.

[92] It was me and a guy named Justin Fargus.

[93] He plays running back for the Oakland Raiders.

[94] And basically what happened, he had a toss.

[95] And he was wide open, you know, basically screaming up the field.

[96] I was in the deep cover, too.

[97] And it was funny because he was running towards the sideline.

[98] I was running towards him.

[99] And we were both heading towards the sideline.

[100] And it was almost like neither one of us was going to back down because we knew it was going to be either a big collision or not.

[101] Because he could have ran out of bounds.

[102] But I just knew he was going to try to run.

[103] run me over just watching them in film so essentially what happened was we basically ran full speed into each other and pretty much knock each other out and I try to get up a little too soon and I fell back down and I was wobble in need and eventually the trainers pulled me out and you know they're like you can't go back in right now and actually he he came out for a few plays too so we both knocked each other out so but you tried to stay in the game I did you know as a as a competitor you know you Because you never know if he's going to get up or not.

[104] So you want to be the first one to get up and you want to make sure that you didn't take, you know, the loss right there.

[105] So essentially, I think I won because I got up before he did, even though I did, you know, kind of wobbly knee and went back down.

[106] What did your actual head feel like afterwards, like immediately afterwards and then later on?

[107] It was really, it's a really odd feeling.

[108] The first thing you get is everything starts to vibrate.

[109] It's like if you laid your head on your, cell phone and put it on vibrate and someone called you that's what it felt like for me and so the instantly i actually saw it on film instantly like i grabbed my helmet and i tried to steady everything and then after that initial um vibration um it's almost like you're kind of in a dream you're just kind of floating and your legs are like jello you're trying to stand up and your mind is trying to tell your body to do it but your body and everything is disconnected so you you pretty much just fall flat back on your face, you know.

[110] Ouch.

[111] Our brains are designed to float around inside the skull to survive the daily bumps of life.

[112] But playing football's different.

[113] It's one tough guy running full speed into another guy traveling just as fast in the opposite direction.

[114] I asked Dr. Cantu what can happen to the brain in a collision like that?

[115] Well, the best analogy, or at least one that I think is useful, is to think of jello in a bowl.

[116] And if you hit the bowl very forcefully, you'll see the jello oscillate.

[117] And if you put the jello into a bowl that is elliptical in shape, not round, and hit it, because you'll invariably hit off center, you'll see that the jello moves forwards and backwards, and it also spins around in the bowl.

[118] And those are the primary forces that are imparted to the brain.

[119] the linear forces are those that are in one plane, front and back, or side to side, and the spinning forces are the rotational forces.

[120] And those combined forces cause shearing and straining of brain tissue, and that in turn leads to a metabolic cascade of dysfunction that is what we refer to as a concussion.

[121] A metabolic cascade of dysfunction.

[122] a big hit on the football field, the only thing standing between your brain and a beating like that is your helmet.

[123] Dr. Cantu is also affiliated with Noxie, the National Operating Committee on Standards for Athletic Equipment.

[124] It's a group that tries to make football helmets safer.

[125] Well, helmets are better today than ever before.

[126] The actual athletic equipment that is on the market today is better than athletic equipment that's been on the market.

[127] market in the past.

[128] But the problem is, what are you asking that athletic equipment to do?

[129] And if you're asking it to prevent skull fractures, and if you're asking it to prevent most serious subduro hematomas, it does a stellar job.

[130] But if you're asking it to prevent concussion, it can't do it.

[131] So let's see if we have this right.

[132] Modern helmets do a good job of preventing skull fractures and on -field deaths, that's why those numbers are way down historically.

[133] But getting lots of concussions isn't very healthy either.

[134] To prevent them, Dr. Cantu could make a more cushioned helmet, but then you might be worried about skull fractures again.

[135] And then there's this problem.

[136] If you did give football players a more heavily cushioned helmet, what are they going to do with it?

[137] A lot of people think the biggest problem in the game today is that players use their helmets not so much protection, what is a weapon?

[138] The way, for instance, in football, in my opinion, that we're going to have to address this problem, is to eliminate the helmet as the initial point of contact in the act of tackling and even to a certain extent in blocking as well.

[139] Quite frankly, when people didn't have the helmets of the security that there are today, didn't have the face mask, and you had to worry about your knowledge.

[140] winding up in your ear from using your face in a tackle.

[141] You didn't use your face, obviously.

[142] So as the safety equipment gets better, our behavior becomes more aggressive.

[143] Absolutely.

[144] Very much more aggressive, very much more violent.

[145] We've seen the same thing happen in ice hockey as well.

[146] And when you put face and head protection on people, they're not as worried about taking blows to that area.

[147] and so the aggressive nature, the activity is greatly enhanced.

[148] So wait a minute, let's figure this out.

[149] If the helmet, which we think of as a safety device, is being used as a weapon, why not get rid of the weapon?

[150] There are sports we play without helmets, rugby, Australian rules football.

[151] What happens if you try to play American football like they did in the old days, without a helmet?

[152] Here's Quentin Michael again.

[153] it would probably be there'd be a lot less head injuries i know that for a fact and i can tell that um the tackling would actually be a lot different you know you can't you know nobody wants to mess their face up willingly so um you wouldn't go in head first you wouldn't go in trying to destroy somebody you go in just to get them on the ground you know and and you know maybe it wouldn't be as exciting or i'm not sure but i know there definitely would be there wouldn't be as many injuries.

[154] Would it be as much fun?

[155] I assume you really like to hit, right?

[156] Hitting his...

[157] Yeah, I like the contact.

[158] That's what makes the game fun.

[159] You know, he got these receivers out there taunting you and you finally get a chance to wallop them, you know?

[160] So that's good for me. All right.

[161] So if, so for someone like you who loves to hit, especially these spindly little receivers who are always yapping, right?

[162] And you get your, you get to pay them back once in a while.

[163] And if you You took away a helmet, right?

[164] If you took away helmets, could you still have a lot of fun playing the game?

[165] I don't think I would.

[166] You have to wonder, if a guy like Quentin Michael doesn't have fun playing football without the amazing collisions, how much fun would we have watching it?

[167] And if you think it's fun watching two football players run into each other head first at 20 miles an hour, how about 20 cars crashing into each other at 180?

[168] I started my career with a bad wreck in 1983 of Daytona.

[169] This is Randy LaJoy.

[170] He was a NASCAR driver for about 20 years.

[171] He won 15 races in more than $7 million.

[172] And I was passing Sterling Marlin to qualify for the Daytona 500, and the car hit the bump, got sideways, slid a long ways, and Richard Petty had told me a story two weeks earlier while we're testing.

[173] He goes, man, you're going fast down here.

[174] He says, you're going to crash, and when you do, there's two things are going to happen.

[175] He says, you're going to either crash real quick and slide a long way, or you're going to slide a long way and crash real hard.

[176] He goes, and if you could remember, before you crash to reach down and pull your belts as tight as you can get them and take a deep breath, you'll be a lot better.

[177] Well, as I'm sliding, and I see where I'm going to hit, I reach down and I tugged down my belts as hard as I could.

[178] You know, in your early years, you're learning not to let go to stairwell, so I put my hand back on a steering wheel.

[179] And when I looked out the windshield and all I could see was sky, I said, well, what's about time I need to take a deep breath?

[180] I woke up in the hospital at night, had a severe concussion, was dizzy for, you know, some people say I'm still dizzy.

[181] But I had a headache for a couple weeks.

[182] But, you know, three weeks later, I was back, NASCAR North Racing, and then we won the champion.

[183] ship.

[184] So, you know, it didn't bother me. It didn't kill me. And I went back to win three races at Daytona.

[185] So Randy has seen Sky.

[186] He's seen Wall.

[187] And he's seen safety gear get better and better.

[188] Now that he's retired, he makes super safe aluminum seats for race cars.

[189] Some of the equipment, the fire suits and the helmets were definitely as good as they could have been.

[190] But one of the things that we have realized is a head and necker.

[191] restraint, something that holds your head on, because if your body's strapped in, your head is not attached to anything, and you'll get the Dale Earnhardt, Kenny Irwin, Adam Petty, Tony Roper, Blaise Alexander, I mean, those guys before him that passed away with the same injury that we lost Dale with, you know, once we lost the best we had, NASCAR says, okay, we got to stop this.

[192] So, I mean, years ago, I mean, if something happens, when you put the helmet, and you pull that strap tight, people say your brains go out the window.

[193] And that's a very good possibility.

[194] Tell me how all this safety in NASCAR, especially since 01, has changed the sport, whether from a spectator perspective or from a strategy perspective or whatnot.

[195] Well, we're not going to any more funerals, which is good.

[196] How it has changed the sport is the new generation drivers, you know, they're not as sore on a Monday.

[197] day of Tuesday has the older generation drivers.

[198] You look at a 50 -year -old NASCAR driver that's retired other than Mark Martin, you know, they have trouble tying her own shoes because it will beat up pretty hard.

[199] You know, your body's stretched that they have trouble walking.

[200] You know, not a lot of difference than the older football players, you know, I mean, but we didn't get as many concussions as they did, but there's still a lot of guys out there that have hit their head.

[201] If I hit my head one more time, I could probably hide my own Easter eggs.

[202] Now, the risk, I guess, is that in other realms, maybe in racing as well, the more safety features you add on, the more reckless or the more aggressive people tend to get.

[203] And in racing, there's a lot of aggression already.

[204] So do you think about that?

[205] Do you think about the fact that as the walls, the cars, and the equipment get safer, that there's going to be more aggression in the end?

[206] Well, I mean, racers were always aggressive.

[207] I know the walls that I hit before there were the soft walls, the safer barrier.

[208] It hurt a lot more.

[209] The concrete walls hurt a lot more than that safer barrier does.

[210] And one of the things that the drivers of this error haven't felt is really a concrete wall.

[211] It makes sense.

[212] If you're not worried about hitting a concrete wall, you might drive a little harder.

[213] Take a few more chances.

[214] If you're all strapped into your car, surrounded by a big exoskeleton, you don't feel so vulnerable anymore.

[215] As a kid, tell me what was the car you remember driving as a kid in the back seat with your parents?

[216] What did they drive?

[217] 1972 Impala Station wagon.

[218] I think it was a 72.

[219] It was the one, it was a 74.

[220] I can't remember.

[221] It was the one with the rounded back and the tailgate went down underneath the car.

[222] Do you remember that?

[223] Didn't swing open.

[224] Oh, it's ugly.

[225] You might recognize this voice.

[226] It's Glenn Beck, the talk show host.

[227] Welcome to a special edition of the Glenn Beck program.

[228] I like to call it our egghead hour.

[229] Now, compare, now your younger children now are under 10?

[230] Mm -hmm.

[231] Okay, so compare now the kind of environment you were in safer -wise as a kid.

[232] No, there's no, I mean, we didn't even wear seat belts.

[233] We were, I mean, I remember, you know, sitting next to my dad, and, you know, maybe I was eight.

[234] I'm like, dad, let me drive, you know, and he said, you're a steering.

[235] a little bit.

[236] I mean, it was nuts.

[237] It was nuts.

[238] Now, you know, uh, you know, everybody's belted and in, you know, safety harnesses in the car seats and my wife, we were, where were we, um, we were someplace recently.

[239] And, um, this kid was sitting and must have been, I don't know, about six.

[240] And we were at a stoplight and, And she saw the kid stand up out of the seat and lean over the shoulder of her dad who was, you know, driving in the car.

[241] And my wife was like, oh my gosh, they're not belted.

[242] I mean, it was like, you know, I don't know, we've got to call SWAT.

[243] Quick, get the belt police out.

[244] I mean, it's like, it happened.

[245] You know, we all lived.

[246] We survived.

[247] It's okay.

[248] These days, Beck drives a Mercedes sedan.

[249] It's new, shiny and black.

[250] everything is in its place I hopped a ride home with him the other day I asked him why'd you buy this car in particular I was standing in the dealership and it was because I was looking at an Audi as well and and the guy you know said to me he said you know just this has some amazing safety features it knows when the car is going to roll if your window is rolled down it immediately rolls your window up it has the side airbags your seats depending on what the car senses it's going to do it puts the seat in the right position you know I mean it's it makes me want to flip the car I'm going to put my seat in the most awkward position and I'm going to flip it this is like the safest car on the road he used the term death proof but I I honestly, I didn't even think about it until I was driving it.

[251] And I thought, I know, I've taken a corner.

[252] I really was taking a corner a little too fast.

[253] And I'm like, I can handle it.

[254] What's the worse it can happen?

[255] So Glenn Beck buys a car that a salesman calls deathproof and finds himself driving a little more recklessly.

[256] Football players get better helmets.

[257] They start using them as weapons.

[258] Is there a way to describe this behavior?

[259] Economists like Steve Levitt know it as the Peltzman Effect.

[260] So the Peltzman effect, which is named after a good friend of mine, Sam Peltzman, a colleague of mine, one of the most outlandish dressers who's ever walked the earth, is the idea that you can put in a safety device.

[261] And people can then feel so much safer in the activity they're engaging in that they take more and more risk to the point where you actually have the opposite effect that by putting the safety device, you make, you lead to more, people being hurt or killed.

[262] And the classic example people talk about is seatbelts in cars.

[263] And the idea would be without a seatbelt you feel at risk, with a seatbelt you drive in a much more dangerous fashion, and that could lead to more deaths.

[264] Now, you sound skeptical.

[265] I do not believe that there ever has been convincing evidence of a single peltsman effect.

[266] Now, there are little bits and pieces of evidence you can find.

[267] So, for instance, it does seem true.

[268] that after you put in seatbelts and cars, there might have been a minuscule increase in the number of pedestrians who were killed, but that was overwhelmingly swamped by the number of drivers who were not killed and passengers and cars who were not killed because they wear them.

[269] One thing that economists understand well is that people respond to incentives.

[270] That's what economics is at its root, is trying to understand how people to respond to incentives.

[271] The peltzman effect is a very deviant over -the -top example of that in which people respond so strongly to the incentives that they actually end up undoing the benefit that the safety device was supposed to have in the first place.

[272] I've got to agree with Levin, at least when it comes to driving.

[273] There are fewer traffic deaths per mile in the U .S. than ever before.

[274] And that's because of safety measures like seatbelts, not despite them.

[275] Sure, Glenn Beck might feel invulnerable in his death -proof car, but since his own safety is at stake here, and that of his wife and kids, he surely doesn't want to get too reckless.

[276] But what about safety gear that protects you while harming someone else, like a football helmet?

[277] Or what about all the radiation we absorb in medical tests?

[278] Radiation that probably causes cancer?

[279] And what about a safety net like legalized abortion?

[280] When you can reverse the effect of risky behavior, like unprotected sex, aren't people more likely to engage in such behavior?

[281] The fact is that our craving for safety has its costs.

[282] The other fact is we spend way too much time being scared of things like shark attacks and terrorist attacks, things that in the end are astronomically unlikely.

[283] We're getting more and more hyped up about a world that's less and less dangerous.

[284] And you know what's really weird?

[285] A lot of the dangerous stuff we do these days, like football, is stuff we do for kicks, not out of necessity, but on our own volition.

[286] If you think about it, risk is becoming a luxury good.

[287] Kind of like Glenn Beck's death -proof Mercedes.

[288] What?

[289] So I didn't stop at the stoplight and I'm going to 190.

[290] What?

[291] I can flip it.

[292] I'll survive.

[293] It's the death -proof car.

[294] What a dope.
