Then, what is your metabolism? And why do some people gain weight when others don't? A lot of that comes down to the fact that we're really bad at keeping track of the calories we eat. So maybe, you know, your friend at work eats a big lunch every day, and you think, gosh, how did he get away with it?

Starting point is 00:00:54 And your other friend who only eats a salad tends to gain weight. But what you don't know is what's going on the other 23 hours of the day. Also, there's an often-cited study on success that actually never happened. And why do humans fight? What drives us to go to war? You basically got a whole bunch of drives as humans, right? And two of them, I think, are really, really important in this question of why individuals go to war. And those two things are status and belonging. All this today on Something You Should Know.

Welcome to Something You Should Know. You know, something that I really enjoy is watching great musicians play their instrument or sing who are at the very top of their game, who are the very best of the best, because they make it look so effortless. And I love that. And maybe you've had that same experience of watching an athlete like a tennis player or a gymnast, and it's just amazing what they can do, and it looks like it comes so easy to them. But the fact is that never, ever has there been a champion who didn't practice a lot. Take any musician, athlete, or any professional, and you will find somebody who spends a lot of time

Starting point is 00:03:00 practicing. And not only is the amount of time that a true champion practices important, it's also how they practice. Researcher Daniel Coyle found that virtually all the people who are the very best in their field practice at the edge of their ability. In other words, they constantly push themselves to the absolute limit, fail, and then learn from that failure. The other important factor is to love what you do. No one has ever gotten to be the best at anything if they didn't love what they were doing. In all the research that's been done on greatness,

Starting point is 00:03:39 no one has ever found anyone who could shortcut this route. No matter how much natural talent you have, no champion has ever made it to the top without lots of practice and the love of what they do. And that is something you should know. Ask anyone what are the things that are most important if you want to lose weight, and they'll most likely say diet and exercise. And the theory goes that if you reduce the number of calories going in and you speed up the burning of those calories with exercise,

Starting point is 00:04:17 that that will accelerate weight loss. Yet when you look at the science, the first part of that equation, the eating less, that is true. That does help you lose weight. But the exercise part is a bit of an empty promise. Well, how can that be? If you exercise more, if you expend more energy, which burns more calories, you should lose weight. Yeah, well, not exactly.

Starting point is 00:04:44 Meet Herman Pzer. He is one of the foremost researchers in human metabolism, and he's author of the book Burn. New research blows the lid off how we really burn calories, lose weight, and stay healthy. Hi, Herman. Thanks for having me. So metabolism is, well, I don't really know what it is. I don't think most people really know what metabolism is, Thanks for having me. Those people can be forgiven because if you look at the public health messaging, you know, how do we fix obesity? How do you take control of your own weight? It's always this double, you know, the two-prong approach, diet and exercise. Well, if you accept that, then you think that exercise is at least half the issue. And if you like exercise better than diet in terms of how you want to change things,

Starting point is 00:05:39 you know, then you're going to want to do exercise more. And it turns out that that's actually a pretty poor tool for weight loss. You really need to focus on diet for that. So how do you know this? I mean, what's the research? Because for so long, I mean, the medical establishment, doctors, weight loss experts, I mean, everybody's been saying diet and exercise, diet and exercise. So but why if it isn't true? As we've seen, for that matter, we've seen with COVID recently, right? You have this health crisis hit. People who are in public health, doctors and researchers, they go, oh my gosh, we've got to help fix this problem.

Starting point is 00:06:18 And they start with what they know, right? And what they know is that being overweight, which leads to a lot of these diseases, being overweight is fundamentally about taking more calories than you burn off. And those same researchers know that if you exercise, well, when you're exercising, you're burning lots of calories, you know? So it just makes sense when we're in the 50s and 1950s, 1960s, 1970s, and the obesity crisis starts to kick in, that people without a lot of great epidemiological data go, look, we need to fix this, guys. And here's what we're going to do. We're going to do diet, and we're going to do exercise. And that's going to be the way that we move forward. And it makes all kinds of sense. And people do get healthier from exercising. So

Starting point is 00:07:02 that seems to make sense. You know, and it all kind of, it sort of grows into this dogma that we all know, you know, quote unquote, know that diet and exercise are these two pieces that are, that you need to have together for weight loss. The science has caught up with that. And just like the science, the directives on how to stay healthy and protect against COVID changed first, you know, very early on, they didn't think masks mattered, but then they realized, oh, actually masks do matter, you know, do this and don't do that.

Starting point is 00:07:28 And just like that messaging changed, not because people changed their minds, but because better information came in and people changed. I think now it's time to use the better information that we have on obesity and begin to update those public health messages. So what changed? How did this new evidence come to light? And I know you were in part responsible for some of this new evidence that exercise is not the way to lose weight. So explain that. Well, I want to tell you sort of how I got into this. As an

Starting point is 00:07:59 anthropologist, I study human evolution and anthropology and physiology. And I wanted to know how many calories you burn if you live in a hunter-gatherer lifestyle, right? Because that's what all humans were doing the last 2 million years or so. And I knew, just like everybody knew, quote unquote, 10 or so years ago before we did this, that because hunter-gatherers are so physically active, they're going to burn tons more calories than everybody else does here in the sedentary, you know, West. And so with a couple of colleagues, I went and I worked with this living, you know, modern hunter gatherer group

Starting point is 00:08:33 in Northern Tanzania, and they are incredibly physically active. They get more exercise. Well, they wouldn't call it exercise. They get more activity in a day than most Americans get in a week. And we measured their energy expenditures with this really sophisticated isotope tracking technique. And the gold standard for how you measure calories burned outside of a laboratory. And when the results came back, it was shocking because even though they are five to ten times more active than we are in the West, the total number of calories are burning every day is the same. So that really blew our minds. And that has led to sort of this body of work that's come out that says, yes, as you do more and more physical activity, rather than ramping up how many calories you burn every day, your body is turning the knobs down, as you say, on other tasks and kind of making room for that exercise, making room for that physical

Starting point is 00:09:30 activity so that the top line number, the total calories you burn every day actually doesn't change even, you know, between really different lifestyles. Isn't that interesting? Because it flies in the face of seeming logic, but it also flies in the face of what everybody believes. Yeah, we got a lot of pushback from that, as you can imagine, because it just seemed really hard to accept. I should say we've done it in other groups now and shown the same result. We can do it in other species and show the same result.

Starting point is 00:10:01 So this is a really widespread phenomenon. And it kind of blew people's minds. And, you know, it's one of these things where the evidence was there in pieces in earlier work that other labs had done, but we were sort of the first to really show it in a strong way and put the evidence together. And it does, it's just so counterintuitive until, and again, I think this is such an important perspective to take until you think about us as an evolved organism, right? And well, what should any organism do? It should take advantage of all the energy it has available in its environment, but not anymore, right? You can't go over. It's like, it's like blackjack. If you go over,

Starting point is 00:10:40 right, you bust. So if you go over the, if you spend too many calories more than you take in then now you're losing weight and you're starving and so your body is built it seems to burn a kind of a very narrow range of calories to kind of keep that energy per day in a pretty narrow range and it's and to spend it as as sort of smartly as you can so if you spend a lot on exercise it'll spend less on other stuff if you spend less exercise, it'll spend less on other stuff. If you spend less on exercise, it'll spend more on other stuff. And that's the new logic, I think, that we have to accept for how our bodies burn calories. What's the other stuff? What is it turning down the knobs on when I do half an hour on the treadmill? What's it turning off? Yeah. Yeah. So that's the really exciting

Starting point is 00:11:24 work we're doing now. We're sort of tracking down all the things that it turns off or turns it down, I should say. The things that it's turning down are really good for your health. Um, let me rephrase that. The things that it's turning down, that reduction has really important benefits for you in terms of your health. So it's turning down, that reduction has really important benefits for you in terms of your health. So it's turning down things like inflammation. It's turning down things like how much you respond to stress, cortisol and adrenaline, right? It's turning down sort of sky high reproductive hormone levels and getting them back in a, in a level that we'd see in a physically active population. And so, you know, lower inflammation, lower stress reactivity,

Starting point is 00:12:09 sort of normalized hormone levels, reproductive hormone levels. These are all really immensely importantly good things that exercise is doing for you. And it's because of that metabolic management. That's really interesting that, and it. And it sort of makes sense. And I guess that's why people who are fit live longer and seem healthier because they're doing that. They're turning those things down. Yeah, absolutely. Absolutely. You know, one of the things that we got pushed, when we first came back with this hunter-gatherer data and said, guys, we need to rethink this because we you telling me then that I don't need to bother exercising? And, you know, the, the plot twist here is that actually this is why you need to exercise,

Starting point is 00:13:13 right? The, the fact that you're not increasing total energy a day, and instead you're changing the way your body burns calories. That's one of the big reasons exercise is so good for you. There's other reasons too that don't have to do with calories. It makes your heart stronger and your brain sharper. So there are lots of good reasons to exercise, not just the metabolic reasons. But in terms of the calories of exercise, the calories burned in exercise, it's not the calories that it adds to your total for the day that's important. It's the calories that it's taking away from other activities that actually aren't very good for you. So it brings up the question then, can you be fat and also be healthy?

Starting point is 00:13:55 This is a big question right now. And the answer is yes. However, we don't know how long that lasts. And so we know, we get people in research studies, we get people showing up with their doctor's offices that are, you know, carrying more body fat than would be recommended. And maybe their BMI, which is a problematic measure, but your BMI might classify them as overweight or obese, but by all the measures of blood pressure, blood sugar levels, all the heart function, all these things, they're actually, they look really, really healthy. And that's great. And that's, you should focus on those numbers in terms of your health rather than the number on the bathroom scale. All I would say is

Starting point is 00:14:35 that it does seem when we look at a population of people that being overweight, being obese does track you. It's, you know, this is a probabilistic thing. This is a risk. We're talking risks now, not certainties, but it does seem to increase your risk of developing health issues later. So if you're healthy now and a little bit heavier than we recommend,

Starting point is 00:14:58 that's great that you're healthy. You still might think about getting your weight to where we, you know, would be considered a more healthy level. It might not be the most important thing on your plate, but it might be something you want to consider. I'm speaking with Herman Ponser. He is an anthropologist and one of the foremost researchers in human metabolism. And the name of his book is Burn.

Starting point is 00:15:20 New research blows the lid off how we really burn calories, lose weight, and stay healthy.

In other words, exercising, you know the old phrase, you can't outrun a bad diet. Exercise is great and it's doing what it's doing, but it doesn't mitigate a bad diet and eating healthy won't make you fit. It'll just make you thin. That's exactly right. You got it. I wish you could write the public health recommendations. We'd be done with this in short order. You know, diet and exercise are two different tools for two different jobs. You know, diet is exercise are two different tools for two different jobs. You know, diet is going to be the tool you use for weight, exercise for just about every other aspect

Starting point is 00:16:51 of your health. And if you can kind of, you know, internalize that two tools approach, you'll be better off. When you looked at the benefits of exercise, is it any exercise or is weight training better than aerobic training or just exercise is exercise? From my point of view, any exercise is good and more exercise is better. You know, if you look at what most Americans are doing, it's nobody's getting close to the amount of exercise they should be getting every day. And so, you know, I think as soon as you start saying, well, you better do it this way or do it that way, people feel compelled, you know, to constrain their choices to those best options. And I don't think there are best options. I think all the

Starting point is 00:17:35 options are good for most of us that just want to be healthy and happy and live a long, healthy life. Just get out and move. So what is metabolism? Because people throw that word around a lot. Oh, I have a slow metabolism. Or, you know, eat this, it'll speed up your metabolism. And I don't think anybody really knows what the word means. Your metabolism is all the work that all your cells are doing all day. Right?

Starting point is 00:18:04 So you've got 37 trillion cells. They're all cranking away are doing all day, right? So you got 37 trillion cells, they're all cranking away, doing all their various tasks and all of that work requires energy, right? Any work takes energy. And so, you know, as you're sitting here, you and I are sitting here having this conversation, our brains are burning tons of energy. In fact, every fourth breath you take is just the oxygen to feed your brain. Our livers are cooking away, our spleens, immune systems, digestive systems, everything. It's all your systems going on all the time simultaneously. So that's right. It's all the work your body's doing.

Starting point is 00:18:36 And so when people say, I have a slow metabolism or, you know, this will speed up your metabolism, what are they saying? And is that nonsense or what? Yeah, that's a tricky one because so metabolism, the amount of calories you burn every day, it's like any other measure of, you know, people like height. Some people are taller, some people are shorter. Metabolism is the same way. Some people burn more calories, some people burn fewer. So slow and fast metabolism is a real thing. But as it happens, that, you know, whether you have a faster, slow metabolism doesn't actually correspond

Starting point is 00:19:11 to whether you feel like you have a faster, slow metabolism. So, you know, when people say I have a fast metabolism, usually that means I can eat whatever I feel like I want to eat. And I don't seem to gain weight. People say I have a slow metabolism. Usually that means I feel like I want to eat and I don't seem to gain weight. People say I have a slow metabolism. Usually that means I feel like no matter what I do, I watch what I eat, but I'm still gaining weight. And that's a different thing. That has to do with the way your brain is wired and how you sort of respond to the reward of food and how you feel hungry versus full. And so these are two different issues, actually, how fast your metabolism is and how fast you feel it is. And so that experience that people often have, I know people who seemingly can eat a lot and eat junk and they never gain weight. And then

Starting point is 00:19:56 there are people who seemingly can't. So what is that? Why can two people seemingly, you know, same age, same size, roughly, some people get fat and some people don't. It seems to defy logic. A lot of that comes down to the fact that we're really bad at keeping track of the calories we eat. So maybe, you know, your friend at work eats a big lunch and he eats a big lunch every day and you think, gosh, how does he get away with it? You know, because he's not overweight. And your other friend who only eats a salad tends to gain weight and always has a hard time, but what you don't know is what's going on the other 23 hours of the day. Right. And we know that if we ask people to keep track of what

Starting point is 00:20:33 they eat every day, they miss about 30% of the calories they eat, right? That's almost, that's like a meal a day that people just have a really hard time keeping track of. Um, and so so that's really what's going on. There's no magic here, right? If you're eating those calories, then you have to burn them off or add them as weight. So the algebra doesn't change. The math doesn't change. It's all calories in, calories out. But the way that feels is going to be different for different people. And so when people say they want to lose weight, what is the best way to lose weight? gap in what we know we need to do and what we feel we can do, there jump in all the fad diets, keto or whatever it is these days.

Starting point is 00:21:33 And all of those diets are really about one thing, which is getting you to where you eat fewer calories, but feel full, right? Because if you feel hungry all the time, then that feeling of hunger is always gonna win, right? Feeling hungry will push you into a pride alliance if you need to. It'll certainly push you into the refrigerator. And so the trick is how do you find a diet that works for you and the way that your brain is wired that makes you feel full on fewer calories? And the answer is? Well, what I can tell you is what the principles are, and these are

Starting point is 00:22:05 tried and true from decades of research. One thing is you can look for foods that are high in protein and high in fiber because those will make you feel full on less. And the other thing you can do is avoid ultra-processed foods because we know from a lot of really cool work, but some really interesting work recently out of the NIH, that if you eat an ultra processed diet, the stuff that comes in a package and has a mascot on the front and an ad campaign that will push you to overeat because those foods are engineered literally to be over consumed. So, you know, eat proteins and fiber, avoid ultra processed foods. Those are the principles you need to stick to. Why do you think that it's really been in the last, I don't know, what, 50 years or so that this has become a problem?

Starting point is 00:22:57 If you look back at pictures of people in the 40s and the 50s and even the 60s, you know, at just Main Street, USA, you don't see a lot of heavy people necessarily in that picture. Now you do. Yeah, well, this is the million dollar question, the trillion dollar question globally, right? Why is it that obesity has become this worldwide crisis? And, you know, again, that the public health messaging on this is always, well, it's diet and exercise. Well, they're right about one thing, you know, obesity comes down to this balance of how many calories we bring in in our food and how many calories we burn off. And so, you know, if you're not burning those calories off, they add up as fat and there's your obesity crisis. So is it the energy coming in or the energy going out the calories we eat or the calories we burn off?

Starting point is 00:23:49 We've done a lot of work that shows that it can't be the calories you burn off because that's actually really hard to move. And we even have really good data since about the 80s. We don't have it going back as far as the 40s. But if you measure how many calories people burn, that hasn't changed at all in the last three or four decades. But what has changed then is how many calories people are eating. And there's lots of good data that show that that's the case. So not only are the total number of calories that we consume as a nation per capita increasing, but, and I think this is really critical, the amount of food in our diets that's coming from these really processed sources, canned foods, packaged foods, ready to eat stuff, that's all been these really processed sources, you know, canned foods, packaged foods,

Starting point is 00:24:31 ready to eat stuff. That's all been increasing every decade since the obesity crisis started. And so I think if you had to point to one thing, it would be processed foods. And, you know, don't forget those, it actually is, you know, since the 40s, since that World War II, that's when processed foods really took off, right? Canned foods. And some of that was for the war effort and everything else. But, you know, those technologies really haven't been around since before then. And guess what? Neither was obesity. I have heard that exercise is good at maintaining weight. Is that true?

Starting point is 00:24:58 Or is it just that it's part of a healthier life and you just kind of overall, if you're going to exercise, you're probably watching your diet better and it's all feeding into the same thing or does it really? Well, no, that's interesting. That is a little piece of the puzzle here that exercise does seem to shine. If you've managed to lose weight, and usually people are losing that weight through dietary change, keeping it off exercise seems to be a big help there. And we don't know if that's because it helps regulate, you know, intake and expenditure signals in your brain. You know, a lot of the work that I've done suggests that the amount of calories that your body burns every day is sort of kept within a really narrow range. And so it could be that if you lose weight,

Starting point is 00:25:41 well, now your body's burning fewer calories because you're smaller, but it wants to burn that higher calorie number. And so by getting your energy expenditure back up with exercise, you're able to kind of get back to where you were and keep your body within that same set point that you're built to have. We're not sure yet exactly how that works out, but it's definitely true that the observation that people who exercise have a better time keeping weight off. Well, I think for a lot of people listening, myself included, what you've been talking about comes as news, interesting news, particularly about exercise and weight loss. But everything you've been discussing about how the body works, metabolism,

Starting point is 00:26:19 and all that is probably more than I, certainly more than I ever knew about it. And it's really interesting to hear. Herman Poncer has been my guest. He is a researcher in human metabolism and author of the book Burn. New research blows the lid off how we really burn calories, lose weight, and stay healthy. And you'll find a link to that book at Amazon in the show notes. Thanks, Herman. Thanks, Herman. Thanks, Mike.

People who listen to Something You Should Know are curious about the world, looking to hear new ideas and perspectives. So I want to tell you about a podcast that is full of new ideas and perspectives, and one I've started listening to called Intelligence Squared.

Starting point is 00:27:35 It's the podcast where great minds meet. Listen in for some great talks on science, tech, politics, creativity, wellness, and a lot more. A couple of recent examples, Mustafa Suleiman, the CEO of Microsoft AI, discussing the future of technology. That's pretty cool. And writer, podcaster, and filmmaker John Ronson, discussing the rise of conspiracies and culture wars. Intelligence Squared is the kind of podcast that gets you thinking a little more openly about the important conversations going on today.

Starting point is 00:28:10 Being curious, you're probably just the type of person Intelligence Squared is meant for. Check out Intelligence Squared wherever you get your podcasts. As you look back through human history, one thing that's pretty constant as far back as we can see is war, fighting. And groups fighting in wars against other groups has resulted in major changes. Wars change the course of humanity. But have you ever stopped to wonder, why does it take a war

Starting point is 00:28:46 to change things? Why do people fight with other people? What is it that for centuries has caused humans to fight and try to destroy other humans for some cause or some gain? It seems barbaric, and yet some people willingly go to war and willingly die for their cause, which seems to fly in the face of self-preservation. So why do humans fight this way? Well, someone who has studied this is Mike Martin. He's a visiting research fellow at the Department of War Studies at King's College in London. He served as a British Army officer in Afghanistan,

Starting point is 00:29:26 and he is author of the book, Why We Fight. Hey, Mike, so you've had some really up-close and personal experience with fighting and war, which is what led you to explore this topic. So let's start there. Explain that. I spent about six years in the British Army. Two years of that I spent in southern Afghanistan. And it seemed to me, it was really obvious to me that the reasons that we spoke about why we go to war, those things that you were talking about, why is it that we do this? And often we talk about religion or ideology, or perhaps we're trying to make the world a better place. They didn't match what I saw in front of me, where most of the people working in different conflict zones and studying and really trying to grapple with this problem of why it is that we fight and go to war.

Starting point is 00:30:33 Well, you've described it as a problem just then. Is it a problem or is it just human nature? This is what people do. It's definitely human nature. We've also built these cultures around war as well, right, that reinforce that nature. But, you know, it's not human nature we've also built these cultures around war as well right that reinforce that nature but you know it's not a problem because in the sense that war actually does tremendous things it is a force in human society and so we have great leaps in technology wars help us build bigger societies and so on and so forth but But what I think is a problem is that we don't really,

Starting point is 00:31:05 even now, when we can develop a vaccine for COVID in nine months and then get it to market in 12 months, when we can do that, but we can't answer this fundamental question about humanity, which is why we fight. And I'll explain really clearly what the problem is. In evolution, the aim is to survive and reproduce, right? And humans are animals. So therefore we have to obey the laws of evolution. So the question is, why do people go and fight in wars when they as individuals are dying for perhaps an abstract ideal or certainly the wider group? That makes no sense in evolutionary terms. And we have to try and understand why that is. Yeah. Well, why is that?

Starting point is 00:31:50 Because it does seem to defy common sense and, as you say, the laws of evolution. You basically got a whole bunch of drives as humans, right? And two of them, I think, are really, really important in this question of why individuals go to war, and at the extreme, why they sacrifice themselves to groups. And those two things are status and belonging. So seeking status, so a higher position within your social group, and then belonging, so belonging to a coherent social group. And, you know, as befits these mechanisms that have evolved, we've got bits of our brain that handle that. And we've got hormonal pathways that drive us to seek those things.

Starting point is 00:32:34 And testosterone helps us seek status and oxytocin is the hormonal pathway that helps us or drives us towards belonging in groups. And I argue that it's actually those two things that drive us to fight in wars. And the other things that perhaps more traditionally we thought drove us to fight in wars like religion, perhaps ideology. And this is not just wars as in the Second World War. This is also all kinds of group violence. So terrorism would be an example. And we're aware of all the debates around the role that ideology plays in terrorism. But I argue that it's those drives towards status and belonging, rather than these more abstract things like ideologies, like religion or jihadism,

Starting point is 00:33:16 that drive people to commit group violence. Well, I've certainly heard that the desire and the need to join and belong to a group is very much human nature because as humans, we were social and we can't really survive as well or at all by ourselves. But as part of a group, we can thrive. So you're saying that that drive to be part of that group is what sends us to war. Because of the huge advantages to humans and other mammals of living in groups, we've developed these strong drives towards living in groups, whether it's tribes, chiefdomships, nation states, singing in choirs. All of these are kind of group activities that we're driven to do because we feel safe in groups and we're able to use resources and we're able to find mating partners. Now, actually, that mechanism that creates in groups is the same mechanism that creates out groups. You can't have in groups without out groups. It's not possible. They're both tied together.

Starting point is 00:34:20 And so what that means is that when you feel strong feelings about your out group, and I'm talking about on an instinctual level here, of course, we're all, you know, conscious beings with reason, we're able to think past these biases. But the natural bias is when you feel positively about your in group, you naturally feel negative towards out groups. And so when you are receiving antagonism from another group, that causes you to tighten your in-group and become, you feel closer, you trust more, you work together with, you strengthen your in-group. And that, because it's the same mechanism, causes you to project more antagonism towards outgroups. So what you see is these two groups that are fighting each other, and that you

Starting point is 00:35:05 get a kind of ratchet between the two belonging oxytocin mechanisms, where they tend to each trigger the others in group outgroup mechanism. Well, that's interesting, because so what you're saying is that the more that we identify with a group, the more antagonistic we feel towards other groups that antagonize our group. And the more antagonized we feel, the more we identify with our own group, which it's like a cycle that eventually, I guess, sends us off to war. But that decision to fight for one group to go to war with another group doesn't seem all that rational. And certainly now, in modern times, it would seem that, you know, there are other options. There are other things that can be done besides killing each other. Hey, look, Mike, I think there's an assumption that humans are rational. Against all the evidence, I think that's a kind of implicit

Starting point is 00:36:07 assumption. And the rational conscious brain often plays second fiddle, I think, to the unconscious brain. So looking at war, rationally, it makes no sense. On average, the vast majority of people who go to war and fight in wars and countries that fight in wars don't benefit from them. There's a massive destruction of property and capital and people die. And, you know, France in the First World War lost 30 percent of its men between the ages of 16 and 35. I mean, that's just incalculable loss. The US Civil War, which if we projected it to today's population sizes of the US would be a 5 million person loss. I mean, it's unbelievable. So, you know, you say we sort of jump to fighting,

Starting point is 00:37:03 but I think the reason we do that is because we are guided by our emotions. That's what guides our decision making. And our conscious brain tends to come along slightly later and justify to other people why we've taken particular actions so when we're going to war you know we're driven by these subconscious emotions very strong emotions towards status which is really vitally important in an evolutionary sense towards belonging which is in an evolutionary terms whether you belong to a social group or not if you think back to the you know the environment that we did most of our cognitive evolution and in the planes the savannas Africa, whether you belong to a group or not is a question of survival or not. So we're really strongly driven to fight in groups, to live and belong and fight in groups. So if you look back, at least through popular culture, and that's, I guess, the only lens I can look back through,

Starting point is 00:38:03 you see that in the past, World War I, World War II, and earlier, that people gladly went off to war. But in the Vietnam era, that seemed to change. Is that perception that people gladly went off to war baloney, or did people gladly go off to war? No, I think they did. I think there's overwhelming historical evidence that people went to the first world war. I mean, again, in Britain, we had this phenomenon. In the first world war, there was no conscription. We had this phenomenon of pals battalions.

Starting point is 00:38:40 So everyone in a, in a factory or a mine would sign up and the supervisors would become the non-commissioned officers. The owners of the mine would become the officers of that regiment and the coal miners would become the soldiers. And speaks to this sense of belonging. the British army recognized this they very clearly were organized and continued to organize themselves along those lines and so when those battalions went to the front and you know it was a great adventure it was a great way to demonstrate your group membership they went as you know the 14th Manchester Rifles, brackets, Manchester Coal Mines or whatever, because they had that sense of identity and belonging. And so absolutely, I think the system was very cleverly organised to speak to higher values of nationalism and patriotism. Are

Starting point is 00:39:39 you a member of this group or not is effectively what the government said absolutely people went gladly to fight those wars and I think Vietnam was a bit different in the sense that it was more abstract it was further away it was also you know 50 years further on with you know mass media penetration and so there was I think there I think society was different then, so perhaps we felt differently about war. So I think there are a number of differences. But we have a number of examples throughout history where people have gladly gone to war. And I think this speaks to this idea that we've been speaking about today, where people are driven by these very strong subconscious urges to fight in wars. So we've heard it said, people have stated the opinion that, you know, if women ran the world,

Starting point is 00:40:33 we wouldn't have this testosterone driven war type mentality. What do you think? If women ran the world, would we have fewer wars? So look, men and women are different and we need both sets of skills and abilities and drives to make the world work. But in short, I do think that we need more women in positions of leadership. If you look at peace agreements, right, at the end of conflicts, and I'm talking about, you know, since World War Two, we haven't had any really major conflicts when we had a couple of big ones. But there have been lots and lots of insurgencies and civil wars. And, you know, the Cold War was was replete with them. But even since the Cold War, we've had lots of internal wars. And what the data tell us about those wars is that if

Starting point is 00:41:26 women are involved in the the peace negotiations and the peace agreements as as not just observers but actually at the negotiating table what we find is that um it's 30 30 to 40 percent more likely that those peace agreements will hold over the long term. So up to 15 years. So this is non-trivial. This is really, really, really important. If we're interested in peace, then we have to include women in the negotiations. Do you think we will soon come to a day where people look at war and go, you know, as an individual,

Starting point is 00:42:26 an average individual on the planet is less likely to die from war or be murdered than any other time in history. So I don't think we're going to come to that realization. I think we're driven by our unconsciouses. And I think one of the things, we haven't touched on it fully here, but one of the things that reduces levels of violence is our ability to build groups and to build bigger groups.

Starting point is 00:42:50 And that's because groups, by definition, are internally non-violent. There's lots of problems in the world today that sit between the national level and the global level. So climate change, data, taxation, maritime ecosystems, desertification, et cetera, et cetera, et cetera. And we don't have sufficiently robust international agreements to deal with those problems. And when groups stop solving problems, they tend to end up in war. They tend to regress that upward movement into bigger and bigger groups, which has happened throughout human history, tends to reverse and they tend to splinter and go into smaller groups. And so I think there's probably a 50-50 chance that this decade will end up in a fairly major

Starting point is 00:43:40 global war. It's not a great message to have to deliver, but when I look around at some of the trends like demography, like shifts in economic power, unless some of those trends go in other directions, I think that we are going to be in trouble. Well, tough message to end it on, but I think this is really insightful to help people understand why, as you look back through history, humanity has been plagued by war. And it's really helpful to get an understanding as to why we do that. My guest has been Mike Martin. He is a visiting research fellow at the Department of War Studies at King's College in London. And the name of his

Starting point is 00:44:25 book is Why We Fight. You'll find a link to that book in the show notes. Thanks, Mike. If you read any book on personal success, or you could just Google personal success stories on Google, and you are bound to come across the famous 1953 Yale University study on goal setting. In this study, researchers surveyed Yale's 1953 graduating seniors to determine how many of them had specific written goals for their future. The answer was 3%. Twenty years later, researchers polled the surviving members of the class of 53 and found that the 3% with goals had accumulated more personal financial wealth than the other 97% of the class combined. Wow, that's pretty incredible.

Starting point is 00:45:22 The only problem is, the study never happened. Tony Robbins, the guru of personal achievement, mentions the study in his book Unlimited Power. When he was asked where he heard about it, he said he heard it from fellow guru Zig Ziglar. When Ziglar was asked where he heard it, he said he heard it from Tony Robbins. According to Yale University, and they've been asked this several times, the whole thing is a myth. It was all made up. And that is something you should know.
