The Jordan Harbinger Show
1276: Coltan Scrivner | The Evolutionary Logic of Morbid Curiosity
27 Jan 2026
Chapter 1: What is the psychology behind morbid curiosity?
Jordan here. Before we start this show, I want to let you know this episode contains violence and some explicit themes, so no kids in the car for this one. And if you leave the kids in the car and you still play the episode, don't blame me when they have nightmares. Coming up next on the Jordan Harbinger Show.
Darwin, of course, was famous for his theory of evolution. He was a theorist. Heard about this story from a zoologist named Alfred Brim, who gave a story about these monkeys that saw a snake inside of a bag. This was an experiment that he did. A monkey would look inside the bag and scream, and then another monkey would come up and look inside the bag and scream and run away.
The other monkeys had to come up and see it because he survived. That other monkey survived. He was fine. And he signaled danger. So I kind of want to know what that thing is. And that's a very similar thing to, oh, this thing is terrible. You don't want to see it. Now I kind of do.
Welcome to the show. I'm Jordan Harbinger. On the Jordan Harbinger Show, we decode the stories, secrets, and skills of the world's most fascinating people and turn their wisdom into practical advice that you can use to impact your own life and those around you.
Our mission is to help you become a better informed, more critical thinker through long form conversations with a variety of amazing folks, from spies to CEOs, athletes, authors, thinkers, and performers, even the occasional drug trafficker, former jihadi, or four star general.
In fact, if you're new to the show or you want to tell your friends about it, and I always appreciate it when you do that, I suggest our episode starter packs. These are collections of our favorite episodes on topics like persuasion and negotiation, psychology, geopolitics, disinformation, China, North Korea, crime and cults, and more.
That'll help new listeners get a taste of everything we do here on the show. Just visit jordanharbinger.com slash start or search for us in your Spotify app to get started. Today we're talking about why so many of us are drawn to things that are objectively disturbing.
Horror movies, true crime, car accidents we can't stop staring at, haunted hotels you swear you'd never pay for, but you still want to hear all of the details. Are horror fans secretly violent? Is morbid curiosity a bug in the human brain, or is it a feature that kept us alive back in the day? And why does Halloween feel cozy to some people,
even though it's basically a celebration of morbidity and death. We're getting into the neuroscience of fear, why scary play works, why empathetic people often love horror, and why enjoying blood in Mortal Kombat doesn't mean you're about to snap even if Nintendo really wanted you to think so.

Chapter 2: Why are horror movies appealing to some audiences?
I don't know why. Of course there is. But I always grew up thinking horror movies were scary. I didn't really like them. Yes, I watched them sometimes, but like on TV. So they're all edited down and they weren't that bad. But then when I saw something like Saw, because a girlfriend of mine was interested in horror movie, I was like, what kind of morally bankrupt people are
are watching all of this and what was really creepy about her was she would be knitting while we were watching someone get their head. She's just like relaxing. Yeah, she's just relaxing and someone's getting their head chainsawed off and she'd be like, ew, ew, at least. So what's going on here?
Well, I thought the same thing when I first started studying this. I thought, oh, of course people are studying this because if you talk to anyone on the street or at a bar or wherever, and you just use the phrase morbid curiosity, you ever been morbidly curious? People give you a hundred examples of when they've done that.
Maybe they're curious about this shady guy they met at a club who works in the Congo with coal sand mining. I think that's a form of that, right? And so I thought surely people have studied this. And when I started looking into it, there was just no science on this. And this was not that long ago, maybe five, six years ago, seven at the most.
So I thought, okay, this is interesting as a grad student, right? I found this thing that everyone knows about, but nobody has studied it. That's a goldmine. Yeah. So the first thing I had to do was just try to define it, right? We had all these concepts about what morbid curiosity is in popular culture. So film critics talked about it a lot, especially with respect to horror movies.
And a lot of the film critics had a similar opinion as you at first, where they said, who watches this morally bankrupt stuff? And that was just the answer is like, well, they watch it because they're morally bankrupt or they watch it because they lack empathy or they watch it because they need an adrenaline rush.
And I think everyone just kind of accepted that, including psychologists and media researchers. And I was a little skeptical of that. I thought, OK, that maybe explains some portion of it. But I thought maybe it's really more about the curiosity than it is about needing to see something morally gross because you are morally gross. And so I started looking into it.
And that's what I started to find was that for most people, this really was. A lot like other kinds of curiosity, it just happened to be about something that was dangerous. So I define morbid curiosity as an interest in or curiosity about things that are dangerous, right?

Chapter 3: What role does true crime play in understanding danger?
And that can come in nonfiction forms like true crime, is obviously probably the most popular example of that. But I think even the news, like honor news is pretty threat-laden. And then it can also come in fictional forms because fiction does a really good job of tailors the story and the characters to be, in the case of horror movies, to be threatening.
It does a really good job of kind of pulling on those cognitive strings. And so it attracts us in the same way that real threats or stories of real threats would.
I'm thinking of Stephen King's It, and I remember being like, a clown? How scary can that be? And then it's a clown, and then it's also sewers, and it's also sharp teeth, and it's also, I don't know, it goes after kids particularly.
Well, that's what makes it scariest, right? Some of the work that I'm doing now is looking at, how do we even define what horror is, right? We have this conception, again, if I see a horror movie, I can say, oh, that's a horror movie. But I have a hard time, like, coming up with a recipe for what makes a horror movie. The traditional answer, again, has been if it scares you.
That's kind of a flimsy definition, right? Because what scares me may not scare you or what scares you today may not scare you in 10 years. And then there's this definition of if the creator meant for it to scare you, like their intention was to scare you. And I was like, okay, that's an okay definition.
But again, if a director creates something that's not scary to anyone, but they intended it to be scary, does that make it horror? Or if it is scary to everyone and they didn't intend it to, is it still horror? And so I was trained largely in biology, right? I think about these things as a biologist and I think, okay, what in like the format of the animal kingdom, what would this look like?
So we tell stories where there's a protagonist and an antagonist. That's a pretty typical thing that all animals encounter. There's people they want to ally with and people they want to fight against. And in horror, what I found, and I used LLMs to annotate hundreds of movies, right? So I had summaries of these movies and examples of the characters and what they were like and all these traits.
And what I found was that in horror movies, it was distinctly a very powerful bad guy, powerful villain. So Pennywise and It, right? And that was really unique to horror. It's the only genre where the hero is not very strong, not very capable, or at least is very overwhelmed by the villain.
So in the case of It, again, you have powerful villain, supernatural clown thing, shapeshifting clown, but then you also have just regular kids, right? Which are the most vulnerable protagonists you could imagine. And that creates a perfect formula for a horror story.

Chapter 4: How can we define morbid curiosity in relation to human behavior?
And then I show a chart of the Saw films and how much money they've grossed over a billion dollars worldwide. It's like, well, that means there's a lot of psychopaths running around out there, if that's true, right? So again, I thought, okay, this really needs to be studied, because this is not just the past, you know, thing.
psychopaths just sitting there next to me, knitting in the theater, talking about Michigan football over the dialogue because they know it's irrelevant. She turned out to be a serial killer, but I'm sure that's an exception to the rule.
It's an exception to the rule. Absolutely.
Sorry, Megan. I'm kidding about that. I'm sure she's a successful attorney. So you mentioned that for some people, Halloween, and I assume you mean the holiday and not the movie, gives them a cozy feeling. What's that Danish or Norwegian word where it means... Hygge. Hygge. Yeah, it means cozy. That's kind of the same thing, I would say, is I don't think Halloween, ooh, it's going to be scary.
It's, oh, fake goblins, and there's a Yoda, and there's, oh, here's a couple princesses, and it's a fun kids thing, and it's almost Diet Christmas with a spooky theme in many ways. And so I get that hygge feeling, especially growing up in Michigan. It's a little different in California when it's 70 degrees on Halloween.
But the kids are wearing their costumes and they don't want to wear a coat and they want to come in and show it to you. And all the neighbors are socializing because they're all out on the street with each other's kids. Like, it's a whole... thing. I don't really know if that qualifies. That doesn't seem like the same morbid curiosity, but is that a different angle on the whole thing?
Because it's not really like death and intestines and gore. It's a princess and the latest Disney. It's K-pop demon hunters, but it's everyone and their mother.
Yeah, yeah. I would say it depends, right? So for the kids, it probably is a little scarier, right? We put up some great Halloween decorations, given what I do. And we live in a very Halloween-centric town, and I organize some of the big Halloween events here. And so We have a good Halloween setup. We have a leather face, like a six foot six animatronic leather face.
Texas chainsaw. Okay.

Chapter 5: How do zebras learn to assess predator danger?
They're incentivized to understand or try to understand when their predator is actually dangerous. So when it's hungry in the case of a lion or when it's motivated to hunt. If you have a cat at home, you probably know that cats spend about 20 or so hours a day sleeping. It's like what they do most of their life.
There was a cat behind you for the first half of the show.
Yeah. What was he doing? He was sleeping, right?
Yeah. And I didn't even know if it was real. I was like, is that a Zoom screen of the fake cat? Is it a cat pillow? And then it got down and was like, I'm sick of this interview. Now it's sleeping in another room.
Yeah. He's like, I've heard this conversation before. I'm going to go somewhere else. Yeah. So big cats are the same way. Lions sleep 18 or 20 hours a day. And so, again, when the zebra notices the lion does not look hungry or does not look like it's motivated to hunt and it's in a safe position to observe it, it'll do that because gathering information about it is a good thing.
It can recognize how many lions are out there. Does it look like he's actually hungry? Is he actually hunting?

Chapter 6: What role does morbid curiosity play in human behavior?
Is he really just laying around? So they're assessing their landscape of danger, the landscape of threat. And zebras are not alone here. Gazelles do this with cheetahs. Minnows do this with pikes and water, bodies of water. It's a pretty common instinct for prey animals to, under certain conditions, inspect predators.
Now, humans are really unique because the rest of the animal kingdom, the only way to learn about your predator is to stop and look at it. Can't learn about it from your peers because they can't really speak to you in the same kind of way. You don't have books or transmissible culture in any kind of way. You can't learn about it like that. Humans, of course, have stories.
We can tell true stories, but we can also create versions of stories that are realistic. where we can essentially have an unlimited number of ways that you could interact with something dangerous. And so it's very cheap for us to learn about danger because we can tell it in the form of a story where you really are in no danger when you're learning about it.
And that makes us incredibly morbidly curious compared to other animals.
I read that men and women have fantasized vividly about killing someone. Most men and women have done this. But the murder rate is low. So I guess most of us don't act on these desires. I just thought that was kind of interesting that most people had thought, I want to kill that person. I don't know. Thought I was alone, but I guess not.
Yeah, I thought that was just me. Yeah, that was a study that David Buss did with some colleagues. I forget how many different countries. It was like thousands of people, though, men and women.

Chapter 7: How do dreams relate to threat learning in humans?
It was a little more common with men, but it was like 80 to 90 percent of people or something had fantasized about killing someone. So, of course, you ask the question, well, why haven't they done it? Because there are consequences to killing someone, of course.
Yeah, that's mainly what's keeping me back. Pesky prison and laws and law enforcement just keeping me from murdering everybody who gets in my way.
Yeah, and of course, you have other psychological detractors that motivate you not to murder people. What that study says that's really interesting is that the sort of cognitive machinery is there to plot and plan and be ready to kill someone if you really had to. I think that's what that thing is showing. And so I guess we could talk about that fourth dimension now.
Violence is kind of the center of all of this, right? It's all about not becoming a victim of violence in whatever fashion, whether that's an accident or a predator or a dangerous person or someone you think is dangerous like a witch or other person. It's all about not becoming a victim of violence. That's really what morbid curiosity is about.
But there's still a distinct domain within morbid curiosity that is about violence because there are a lot of ways to learn about violence. So we talked about three of them. One is learning about it by learning about the minds of other people, predicting who's going to be dangerous and when and why. Another one is learning about the outcomes of violence. That's the bodily injuries one.
The third one, the supernatural one, is actually very similar to the minds of dangerous people, but it's about things or people we can't see or access. So we have to like learn about these people who we just don't have any access to, right? The ghosts, the aliens, the gods, the whatever. The violence domain is about just witnessing violence itself and seeing how that unfolds.
We talked about women with true crime and how they're feeling more prepared maybe now that they've listened to this true crime podcast. They carry mace with them or they carry a pen with them or whatever. They know what they're going to do if somebody tries to capture them. I think men do something similar with boxing or UFC. So you watch a UFC fight, right? What are you doing?
Well, you might enjoy the sport or you enjoy the competition nature of it. Maybe you have a favorite fighter. But you're also just watching simulations. I mean, they're real fights. Of course, people are injured, but they're boundaries, right? There's a ref who stops it if it goes too far. There are a few rules.

Chapter 8: What insights can horror movies provide about our fears?
So when I call it a simulation, I just mean that it's not an all out fight. But you're watching the closest thing you can see to an all out fight. And you're seeing what is successful and what is unsuccessful and who is successful and who is unsuccessful and how does that unfold? And I think men do that to a much greater degree than women. Women tend to do the pre-planning thing.
They tend to plan, okay, who's even going to be dangerous? Who can I predict that would be dangerous? And men are a little more interested in the act of violence itself. And I think that maps onto the kinds of violence that men and women are subject to, right? Men are...
killed more than women by far in any kind of violence but women if they are going to be harmed tend to be harmed by someone they know really well which is usually in the case of a true crime story it's like a partner or a romantic interest or someone who's trying to get close to them Men tend to get killed by people they don't know at all. So they tend to get killed by strangers.
And that's true historically as well. Battles and wars and bar fights today. You tend to get injured or killed by someone you don't know. That tends to be how fights are, right? It's not someone you're like living with or someone you're best friends with. It's like a rival or a stranger.
And so I think it simulates something that men historically have had to face, which is the danger of an unknown person or an unknown man. In the case of that, also face-to-face violence as opposed to proactive violence.
Yeah, I do want to talk about video games and violent video games because I remember when Mortal Kombat came out and it was just crazy. And it was like, all right, you have Street Fighter, which is a cartoon guy's fighting. But no, now this looks kind of real, even though they're ninjas or whatever, and they're doing supernatural things.
But like you can throw a spear out of your sleeve and spear this guy and pull him in and then you give him an uppercut and he flies in the air. There's blood everywhere. And then it came out for Nintendo and Sega and it was like the Nintendo version had just some kind of white slop that looked like whatever.
And then if you put in the blood code on Sega Genesis, it had blood and spikes and everything. People were buying Sega just to get Mortal Kombat on there because they're like, I'm not playing this Nintendo version with sweat. Get out of here.
Yeah, I looked into that story because I kind of knew about Mortal Kombat and the fuss it kicked up when it came out on home platforms. It was similar to what happened when slasher movies came out. Slasher movies came out in the 80s, but they also coincided with the release of widespread use of VHS in homes. So people were not just concerned about teens sneaking into a slasher movie.
