The Jordan B. Peterson Podcast
502. Angry and Red: Color as Emotion | Mark Changizi
Thu, 28 Nov 2024
Jordan Peterson sits down with theorist and researcher Mark Changizi. They discuss the biological reasons for mass hysteria on the societal level, why we evolved to have color vision, and how we understand and interpret the patterns of the natural world. Mark Changizi is a theorist aiming to grasp the ultimate foundations underlying why we think, feel, and see as we do. He attended the University of Virginia for a degree in physics and mathematics, and to the University of Maryland for a PhD in math. In 2002, he won a prestigious Sloan-Swartz Fellowship in Theoretical Neurobiology at Caltech, and in 2007, he became an assistant professor in the Department of Cognitive Science at Rensselaer Polytechnic Institute. In 2010, he took the post of Director of Human Cognition at a new research institute called 2ai Labs and also co-founded VINO Optics, which builds proprietary vein-enhancing glasses for medical personnel. He consults out of his Human Factory Lab. He curated an exhibition and co-authored a (fourth) book — “On the Origin of Art” (2016) by Steven Pinker, Geoffrey Miller, Brian Boyd, and Mark Changizi — at MONA museum in Tasmania in 2016, illustrating his “nature-harnessing” theory on the origins of art and language.

Chapter 1: What is the focus of Mark Changizi's research?
You can find information about the tour at jordanbpeterson.com.
It's about this new book, which is about biblical stories, but you should also understand that I'm doing the same thing with these stories that I did with the other tours that I had conducted before, and the other books for that matter, which is to take high-level abstract ideas, in this case foundational narratives, to explain what they mean, but also to explain why knowing what they mean can make a real practical difference in your life.
You know, I want to bridge the gap between the abstraction and the reality so that you can put into operation the principles that I'm discussing so that it does produce a tangible improvement in how you attend to things and how you act. So come out to the lectures if you're interested in continuing with that. Today, I had the opportunity to talk to Mark Changhisi, who...
as an author of this book, Expressly Human and a number of other books. And I wanted to talk to Mark for two reasons. One was because we share an interest in evolutionary biology and evolutionary psychology, especially with regards to perception, emotion, language and mass group behavior. And so I've been trying to wade through the literature on perception
Mark is very interested as an evolutionary biologist slash psychologist in the function of evolved traits like perception. And one of the hypothesis that we discussed, which is a very interesting one was his explanation, rather unique explanation for the evolution of color vision.
He believes, for example, that we have additional color vision, not so much so that we could detect ripe fruit, for example, which was one hypothesis, but so that we can better attend to the emotional signals that people display as a consequence of alterations in their circulation, especially displayed facially.
So we have color vision so that we're better at detecting signs of health or ill health as a consequence of skin tone, but also detecting and reacting to emotional displays. And so join us if you're interested in evolutionary biology, evolutionary psychology, emotion, language, communication, and the behavior of mass groups. So I think we'll start our discussion by talking about perception.
And you've studied visual perception for a long time. And so I'd like you to outline, if you would, what you understand about visual perception. And then we can contrast our viewpoints and see where we can go with that. And I think we'll segue into emotion and language from perception.
Yeah, I mean, so, you know, my background is sort of mathematics, and I went into cognitive science, and I was really more of an evolutionary biologist. And so one of the areas that I've worked and have a bunch of discoveries happens to be vision.

Chapter 2: How does color vision relate to emotional signals?
And so none of the... Stereoscopy always loses. And if you've played first-person shooter video games, you're... Yeah, you have both eyes open, but you're being fed one image on screen. And these things are so immersive. You never are confused as to where the guys are that you're shooting, right? They're always really unambiguously in one particular spot, yet you're a cyclops, right?
So it had occurred to me back then. I said, I don't think it has anything to do with stereoscopy whatsoever. And it turns out it's all about one currency. This is again to this idea of why... Why aren't there three, two or three or more equivalent kinds of functions that are all competing? And then it's just some ugly mess and it's not a good design hypothesis at all.
It's going to be sort of ugly kludge that happens to – it's almost never a kludge. And so in this case, the reason that we have forward-facing eyes and the more forward-facing they are is to see better in clutter. And so what I mean by that, animals that evolved with leaves all over the place. When there's leaves, if your eyes are more widely separated than the clutter leaves, let's say.
So, for example, if you've played this game, if I hold my finger up in front of you, it's very thin, and I look at you, but not my finger, I see two copies. Unless I've got a dominant eye, but for those of you who don't have a dominant eye, you'll see two copies of your finger, and each will be semi-transparent.
Right.
Right. Now, you can see through it. Right. So what one eye is being blocked with, the other eye is seeing the world beyond that. And so your brain has evolved to just create two copies of it. And you're not confused like, oh, my God, I've got two figures. No, you know what's going on. It's just you have this perception that combines them and creates semi-transparency so that you can see beyond it.
Now, even my whole hand, I'm almost missing nothing, even with my whole hand in front of me. There's a little bit of a core in the middle, but I'm capturing most of it.
So for objects that are not as big as this interpupillary distance, the separation between my eyes, then when you're an animal with those kinds of eyes in a forest with leaves that are typically smaller than that, you actually get, I call it x-ray. You actually can see, it's probabilistic summation. You actually can see much, much more of the environment beyond than when you're a cyclops.
So, and in fact, I noticed this playing video games back 20 something years ago, when I would be, you know, because you're a cyclops and you're hiding in bushes and I'd be trying to snipe people. And then when you're in a bush, you can't see anything. Of course, these are fake bushes, I get it.

Chapter 3: Why do evolutionary biologists reject teleology?
So let me ask you one of the things that I've been concerned about for whatever that's worth is –
Online anonymity we know there's an endless number of I think valid social psychology studies Which is a very small proportion of social psychology studies by the way that show that when people are shielded from the reputational consequences of their actions, they're much more likely to misbehave and That that's why for example
If someone steps in front of you while you're walking down the street, you're very unlikely to curse. Whereas if they cut you off in your car, you're very likely to curse. So anonymity facilitates a more psychopathic and impulsive style of responding. And one of the problems we have on the net now is that Anonymity, I wouldn't say reigns, but it's very, very pervasive.
And that means you can say whatever the hell you want with absolutely no reputational consequence. And so my view of the online world, this might be particularly relevant on X, is that anonymous signaling facilitates a psychopathic and sadistic form of social interaction.
Yeah, I hear that a lot. I've argued against that often. And the reason I don't think that's right is every day you have countless encounters with folks in real life at the coffee place or wherever it is, cars signaling to one another and we emotionally signaling in our cars all the time. And you don't know these folks and you're You know that you don't know these folks.
And what's usually, though, there that's not there on the web is full, rich, socio-emotional interactions that are allowing you to go through your day. Yeah, you're embodied. Yeah, you're really able to get along well, I think, because all of your emotional expressions are there. I think that online— And, well, and your habits, too.
I mean— because it's an embodied environment, you're running on the habits that are a consequence of the fact that you are in something approximating an intact social environment.
No doubt, no doubt. But then, and let me give you an example online where things work terribly. Unlike X or Twitter, where we typically don't know people in real life. In Facebook, everybody, you kind of know who they are, like, at least back in the day, you know that that's Doug's friend, that you, whatever, that you kind of have some idea who these people are in real life.
And people are even meaner on Facebook. It's one or other than these little comment arguments. They're just vicious and vile. And they're so mean, even though they know each other. I think that what's I think that really what matters in both of these worlds is having some notion of identity that extends over time and you need to be able to socio-emotionally express yourself as best you can.
