Video summary

The video introduces the concept of "belief landscapes," a metaphorical model used to understand how populations update their beliefs over time. Instead of viewing misinformation as an isolated problem, the speaker argues that people's existing latent beliefs act like gravity on a topographic map, pulling individuals toward stable valleys of thought while others remain in turbulent areas or move freely. By analyzing vast amounts of text data from news and social media using natural language processing, researchers can locate where groups of people sit on this landscape and predict their future belief trajectories with surprising accuracy. This approach allows scientists to identify converging regions, whirlpools of polarization, and areas susceptible to misinformation, offering a dynamic way to study how collective intelligence evolves rather than just looking at static opinions. Beyond mapping current beliefs, the discussion extends to the challenges of aligning artificial intelligence with diverse human values, a field known as value pluralism. Since AI models are often trained on data reflecting specific cultural biases, such as Silicon Valley's liberal worldview, they may inadvertently exclude or misalign with users from different backgrounds. Researchers are currently exploring how to adapt these models to recognize the validity of various cultural perspectives, particularly regarding complex topics like gender and family dynamics. The goal is not to create a culturally neutral AI, which is impossible given that all advice stems from some context, but rather to ensure that technology serves diverse populations by understanding that what constitutes "right" or "wrong" depends heavily on one's cultural environment. The High School at Syracuse University serves as an interdisciplinary hub where technical computer science meets social science, fostering a unique environment for students and faculty to tackle real-world problems. Through initiatives like the C4 Lab and the Center for Computational and Data Sciences (CCDS), the institution connects students with industry leaders and local communities to work on projects ranging from predictive analytics in agriculture to understanding belief dynamics. Students engage in hands-on research without needing funding, collaborating on diverse projects that build technical skills while addressing human issues. This entrepreneurial spirit encourages cross-pollination of ideas between those focused on code and those focused on society, creating a rich ecosystem where students learn to manage AI tools wisely rather than relying on them blindly. Ultimately, the conversation concludes with advice to remain critical of media hype and to engage with new technologies like AI as tools that amplify human creativity rather than replace it. The speaker emphasizes that while the world can seem scary due to rapid technological change, a closer look reveals nuance and great potential. Just as previous innovations transformed how we travel or play music, AI offers new ways to solve problems if approached with an open mind and critical thinking. The core message is to avoid hiding from these changes but instead to understand their structure, use them as targeted solutions within broader frameworks, and appreciate the unique opportunity to bridge the gap between technology and humanity.

Hello, I'm Jeff Hemsley and this is another episode of Infoiversity from the High School at Syracuse University. Today I'm joined by my colleague Josh Intron. He's an associate professor here at the high school at Syracuse and he's the director of the C4 lab and CCBS. Josh studies how social technologies shape collective intelligence and belief formation, including large-scale work like belief landscapes, which is a computational social science project that he's going to tell us more about in a bit. In fact, let's just start right there. When you talk about belief landscapes, what does that mean and how are you studying that? >> Yeah. Well, so belief landscape is a metaphor, right? of course um for trying to understand how populations of people update their beliefs over time. So um let me give you a little bit of history on that and then maybe I'll I'll walk you gently into belief landscapes. So um we all know that you know or or many of us here in the high school have uh focused on misinformation and uh misinformation is really about the proliferation of information that is that is not correct right people are putting it out there and u but I've always been wondering I've always been interested in in in trying to figure out why people believe in misinformation and it struck me that Maybe the problem isn't the information itself, but it's really the uh latent beliefs that people hold that lead them to buy into that misinformation. So, uh I think about 10 years or so ago, I started um looking carefully at beliefs, trying to model beliefs. And um the metaphor or model that I came up with is that uh beliefs could be organized as if they were on a landscape and the population is moving over that landscape as they change their beliefs. Okay? And you can kind of another another metaphor is to think about um beliefs as being a current in a river, right? >> Wait, can you give us a real world example in the like in today's landscape? >> Yeah. So, um you can kind of think about uh conservatives and liberals as being different positions on that landscape. Of course, there's not just conservative and liberal, right? There are lots and lots of little clusters of beliefs here and there. And so if you imagine instead of beliefs moving between people, you have people moving between beliefs, you can begin to think about how populations move across that landscape of beliefs, right? And so, um, I went into this with that model in the back of my head and, uh, through a lot of natural language processing and some really fancy data analytic techniques, I was able to show that this model works pretty well. And in fact, it works so well that once you can locate people on the belief landscape, you can predict with a fair degree of accuracy where their beliefs are likely to go in the future. So you can't necessarily do this with 100% accuracy for an individual, but when you start to look at populations, you can say, "Oh, this group of people who hold these sorts of beliefs will go here in the next half a year, in the next year." And it's surprising how accurate that is. So the landscape metaphor which is you know maybe helps to think about is you can imagine a rough topographic landscape of beliefs and we'll imagine there are stable positions on this landscape and those are the valleys of the landscape and the population of people moving across that landscape are governed to some degree by gravity >> and so they flow into these low regions and they tend to stabilize there. They tend not to move back out of those. Now, of course, people are, you know, unique. People are all over the place. And it turns out that there are some people that are pretty stable and there are some people that are just wild and they're moving all over the place. Um, most people are fairly stable. Um, it's really a a small periphery of people that move all over the place. >> So, in my mind, what I what I kind of envision is like a map with different cities and each city represents a belief space except some cities or some belief spaces have more gravity or are more attractive to people. >> That's right. >> Is that kind of >> That's exactly >> in the ballpark. That's right. So, now to mix metaphors a little bit. >> Yeah. Um, if you take that back to say the uh stream metaphor or the current metaphor, there is actually a lot of movement in this landscape. People are in motion all the time. But in the same way, you don't really see those streams directly until you drop something in the water and you begin to see how those particles move, like leaves on a stream. That's kind of how I do my work, right? Is I model where people are and I look at their collective movements. And so you can begin to identify things like converging regions, little whirlpools, areas where there's a lot of turbulence. And then you can look at how that changes over time. You can look at the emergence of turbulent areas or new strong whirlpools emerging. So this becomes a really powerful way to look at things like polarization and belief dynamics. >> Yeah. So as you talk I think about some sort of per perturbation which probably equates to events that happen in the real world that can shift things. >> That's right. And so part of what I'm doing in my current project is trying to measure the um fragility of an existing belief landscape such that when something happens will we see a massive movement or a shift in the beliefs of the population. So you might not be able to predict COVID, right? But you might be able to say that, oh, we're poised to do some pretty interesting things when a pandemic uh comes along. >> So, the project that I'm looking at is looking for the uh you know, can we can we predict um where social unrest is likely to you know, arise in the wake of certain kinds of events. >> Okay. So in layman's terms, >> how do you model this? How do you study this? Like what kind of data might you use? What what does that look like? Right? So the data that I use is any text data. So I look at anywhere where people might be voicing some kinds of beliefs. So this could be news media, social media of course. Um, and but there are flavors of social media, right? I'm not going to be looking at YouTube videos typically because it's hard to lift beliefs out of that that. But any text data works for me. >> Um, >> could you use Tik Tok data if it was transcribed? >> If it was transcribed. Yeah. Yeah. Um, one of the things that's interesting is, you know, if you look at things like local news organizations, you can do a pretty good job trying to understand the beliefs of local populations by looking at just those news organizations. And so you can begin to understand how beliefs uh are distributed geographically as well. >> Okay, that's pretty cool. So now I know another space that you're looking at is AI and culture and you have some PhD students working in that space. >> Um can you tell us about that? >> Yeah, sure. Um, so I think uh I don't know if Google coined this phrase, but um there's this idea of value pluralism in AI right now, which is that people have lots of different values. What's right, what's wrong is really dependent on context and culture. um there is no you know one-sizefits-all set of values but most of the AI models that are generated are generated from you know handful of tech companies out there and they plug into those tech companies a set of values which might not fit everyone right and so here in you know the US we've got uh you know models that are generated in Silicon Valley and they're channeling usually liberal western progressive values and those don't even work that well in the US right there are lots and lots of people with different ideas and so you have to ask the question what is you know is this are these kinds of models excluding large portions of the population because they're coming into things with these bakedin values that don't really match the end users so what we're trying to do or or my my two uh PhD students are both looking at aspects of this. One of them is looking at um values around not know values is a little narrow actually. She's looking at conceptions of gender across different cultures trying to understand how different AI models uh interpret and promote different views of gender. Um and then my other student is uh this Jinfen is is looking at how you can actually adapt AI models to u do something that recognizes the validity of the values of the enduser. Right? And so the whole point here now there's a the larger question uh you might have heard of the the alignment problem in AI which is how do you make sure that the AI is aligned with human values right but the question then that begs the question what values are we talking about here there is no onesize you know fits all set of values so we're trying to approach that problem by saying well you Since we can't say there's one sizefitsall, one set of values, how do we align AI with different populations of users that are coming from different cultures, different backgrounds? >> Okay. So, from what you're saying, it kind of sounds like you couldn't make AI to be culturally neutral, or could you? It seems really hard to do that as soon as you talk about anything that has, you know, if you want to ask AI for advice. At that point, it's really hard to be neutral, right? From a uh collectivist culture, you know, in the east, you might want to ask, should I move out of my house? Right? And from a western perspective, move out of your house, get a job, do something. From an eastern perspective, spending time taking care of your parents, your aging parents, is really a laudable thing to do. And so these values are going to inform how the AI responds, >> right? >> So let's briefly go back to belief landscapes. >> Yeah. So how is that an high school topic and how do you engage high school students in that kind of work? Yeah, it it intersects with the high school in a couple of interesting ways. Um, from a method standpoint, uh, I am doing things that high schoolers do. We're processing language. We're looking at social media. We're doing computational social science and we're trying to understand the implications there. It's not necessarily that we're looking at how social media influences beliefs yet. >> However, you know, I started with misinformation. The question then becomes, can we identify places that are especially susceptible to misinformation and what kinds of misinformation are they susceptible to? So, you know, maybe we're never going to stem the tide of misinformation. It's been around forever. It's becoming more and more powerful. I don't see how we're ever going to get rid of deep fakes, right? That that that uh you know train has left the station. But maybe we can do something to identify susceptible regions of a belief space. And based on this analysis, maybe we could say, "Oh, this is a kind of belief space that is highly susceptible to misinformation. This might be uh you know in another situation another another set of beliefs might be a highly resilient set of beliefs. It's not like we're trying to change anyone's mind about anything but maybe there are ways we can introduce new sorts of dynamic processes which lead people to be more resilient in the face of bad information. So that's one place where this um you know this sort of intersects really strongly with the high school and with information sciences in general. another my my goal here to some degree um we do do things like try to understand polarization right maybe that's political science maybe it's information science maybe it's communications but it's somewhere in all of those places I think there are a lot of different ways to characterize the dynamics of belief that go on in a population that are not just polarization Right? Polarization is pretty simple. It's based on the idea of a two-pole axis of beliefs. But that's not how beliefs actually work. There's fracturing, right? There are beliefs that are converging on some dimensions and moving apart on others. There are beliefs that are frozen. There are beliefs that are mixing. So using the belief landscape analysis, I develop a much richer vocabulary to describe these dynamics. And from there we can do a lot of other things to think about our uh information ecosystem and how it intersects. >> Yeah, I like how you talk about how your work is actually intersecting with a lot of other fields >> and that's actually kind of a key thing about high schools, right? We kind of sit in between a lot of other spaces, >> right? >> So students that are interested in multiple kinds of things can find work like this interesting from a lot of different perspectives. >> That's right. It's highly interdisciplinary and we're always moving into this theoretical literature or that theoretical literature and pulling down new new techniques. So tell us about CCDS. What is CCDS? Um what's your role there and again how does that fit into the high school and how do students get involved? Yeah. So this year I am the director of the center for computational and data sciences. Uh CCDS has been around for quite a while. Um but I think one of the things that I'm hoping to do with CCDS um is actually turn it into something more of a uh a connector, right? that connects uh students in the high school and faculty in the high school and maybe people across the campus with others in uh in the area like in central New York, right? Industry leaders um who all share an interest in doing some sort of data analytics, right? So we have this uh really dense concentration of people with expertise in data analytics and AI and in the high school we're really interested in realw world problems right >> and so there's a beautiful marriage there between what's going on in the high school what's going in on in central New York at large what's going on across the campus with people processing data And so I envision CCDS to be a nexus of sorts where all of those people could come together. So through that we can provide students with real world opportunities to get involved in data analytics projects, maybe help them extend their networks, right? uh and then we can also centralize data repositories and perform services for uh others you know out out in the world or on campus. Um and hopefully one day we could establish new sorts of research relationships, engagements between faculty here in the high school and people trying to solve real world problems with AI, automation, data analytics, forecasting. >> So now you also are in the process of trying to build some industry connections. >> Yeah. >> Are those things you can talk about? >> Yeah, sure. Um, so we have a uh contest coming up soon. This was a uh a connection we made through made through an high school student, a current high school student. Um, there's a uh company in the U Midwest called Professional Agricultural Marketing. um and they're running a contest here in the high school for high school students to participate in um addressing a couple of the challenges that they're facing with the deployment of AI and forecasting predictive analytics. So, uh they reached out to us and we said we'd love to do that. And so we have I think um a total of 16 student teams starting right now. Um we have a kickoff meeting this Friday and uh they're competing for prizes but also they're gaining a lot of experience with real world problems. Um, and then I've been reaching out to MACE, which is the Manufacturers Association of Central New York. Um, and I think we are going to be running a webinar in early April and I'm working to try to build bridges into uh into industry more generally. Um, there's a center at SU called the Case Center. um and they've been helpful in trying to provide me this contact. So, it's work in progress. I feel like we're a little startup here in the high school right now. >> Yeah. Well, and that's kind of exciting. And in fact, the high school has a long history of being entrepreneurial and starting up things and creating connections. So, it kind of fits right in. >> Yeah. >> So, you also have a lab called the C4 Lab. >> Tell us about that. Well, the C4 lab uh I started when I first uh I'm a I'm a you I have a PhD in computer science and I I did all my work in a lab environment and I like having lots of students working together. I think there's a lot of synergies there and so when I got to the high school I wanted to replicate that environment. So I started the C4 lab. T for stands and I I I don't even remember the ordering but it's uh communication computation cognition complexity that's C4 and uh those are all elements of you know of my interests in my work um and so I have you know at any given day anywhere between 15 and 30 students working on different projects in the C4 lab. A lot of students come to me and they say, you know, professor in drone, I'd love to work on a research project. I say, I don't have any money. And they say, that's okay. I really want some experience here. I really like the idea of learning outside of a traditional course. And so I find spaces and projects. Students come in and they drift out again. you know students are busy but you know quite a few of them get some good experience and they stick around for a while. So within the belief landscape project I probably have five or six students that are working on different aspects of the project. I have students working on a another project, a narrative project. I have students working on another project which is building an app. Um, and so it's a really rich environment and I get a lot of a lot of good collaboration and synergy there. >> Okay, I'm going to switch to teaching. >> I want you to tell me um what classes you're currently teaching >> and you know in education right now there's tension around students using AI to learn things and using it in class and using it. what's your philosophy there >> and and how do you see students applying this in useful ways in your context? >> Yeah, so right now I'm te teaching a graduate course in uh applied machine learning. Um I'm only teaching one course this semester because my u project is pretty demanding um the funded belief landscape work. Uh but uh I've been teaching this class for a few years now. It's evolved a lot especially over the last few years as AI as you might imagine uh has has become really really prevalent. People are using AI all the time. Um, as a programmer, I have about four decades of experience programming and I use AI all the time to do my programming, right? I'm a a good coder, but it's just so much faster, right? And I think that moving forward, we're going to see students using AI more and more and more. And there's really no way to say don't don't don't do that. I think it's possible to use AI and use it wisely to do really powerful things, but that's the trick, right? Is using it wisely because you can say to an AI, do X for me. And if X is too large or you're not paying attention, you have no idea what you're getting, right? And so what I'm doing with my applied machine learning class is focusing really on core theory to try to make sure students are understanding what's going on. But then within the coding part of the class, I try to scaffold interactions with AI so that people students become very effective technical project managers. Right? That's one of the things that I think uh requires a lot of sophistication and is not well addressed in computational classes. It's kind of software engineering, but it's also a lot of what you call computational thinking. thinking about how you break code down into modules, how you make sure that those modules are performing correctly and how you adapt the code as you move forward. That's the kind of thing I'm focusing on right now in class. So rather than sort of put my head in the sand, um I think uh grappling with AI directly and trying to teach students the new skills that they need in order to make sure they're using AI wisely in the course of doing technical work is um that's that's my philosophy. >> So what if there's one thing you want to make sure your students leave with with respect to AI, what is it? H well I think some some you know condensation of what I just said. Um even though uh you can use AI to solve a big problem right now, it's important to keep looking at your problems critically and understanding how they're structured and using the AI as a targeted solution within that structure. So my hope is to make sure that AI doesn't lead students to disengage critically with the technical material that they're grappling with. So I hope to preserve that critical thought that goes into these sorts of uh technical disciplines even though they have AI available to them if that makes sense. >> Yeah. So another thing that I think a lot of students don't realize is there's many times we learn as much from them as they are from us. >> Talk about that. What what are you learning right now from your students? And I know you work with undergraduates and master students and PhD students. H so it's it's hard to put it in a in a nutshell because I learn different things from different students. >> Sure. Right. Um, a lot of, uh, what I learn is, um, how to articulate, uh, things that I have just sort of absorbed over time, but I never really turned into uh, some sort of lesson. I have a lot of intuitive approaches for dealing with things. And I'll say to my students, you know, when I'm first starting out with a CLA class, I'll say, "Do this. It's obvious, right?" And the students tell me, "No, it's not obvious." And so that helps me articulate exactly what it is that you need to do in order to do X, right? Whatever. >> Sounds like good prompting. >> Yeah, it's excellent prompting. And so I have to sort of step in it first and you know figure out oh I just said something is completely uninterpretable and then you know I I once I get the feedback I'm able to fix that. But then you know the other on the other side when I'm working with uh you know PhD and master students outside of the classroom what I get out of that is just the benefit of diversity right you're only one person and and as one person you're going to think some subset of things but as soon as you got a bunch of other people working with you they're going to show you angles to problems that you haven't even thought of. Yeah. And that's sort of the magic of working with large groups of students in the C4 lab. >> All right. So, why should a student come to the high school? What is it that we do that's just really different that's unique? >> Well, um I have a particular I have a particular answer. My answer might not be anyone else's answer. Uh I'm a I'm a computer scientist, right? I come at things with a fairly technical approach. Uh that computational thinking, right? But uh I really uh the things that drive me are the human problems. >> Yeah. >> Right. So I really bring my more technical approach to human problems. And that doesn't mean I reject other modes of thinking. In fact, I I love to be exposed to those other modes of thinking because that's the grist that helps me to learn over time. So, you know, many of the things many of the the the new technologies we're grappling with as um as as a society um as a country are, you know, what makes them hard is not the technology, it's how the technology meets people. Yeah. >> Right. What all these systems, all these human systems we have are going to change dramatically. Right. You can talk about the future of work. You can talk about AI and medicine. You could talk about education. Right? These are all the kinds of problems that the high school deals with. And really nowhere else do you find that, you know, academics that are solely focused on that that that interstitial layer between technology and humans. And we come to it, many of us come to it with a somewhat more technical background, but also an awareness of social sciences and theories. And so that blend of things is really unique and I think maybe one of the most important places people can be working right now. Right? You can throw up your hands and say, "Uhoh, what's going to happen with, you know, the job market, with AI? What's going to happen with crypto?" Right? Well, yeah, that's exactly what we're studying. That's exactly what we do in the high school. >> Yeah. And to add to that, this is the place where a computer scientist like you can work with somebody who does completely social focused work. And so you're going to get those other perspectives that you were talking about earlier, right? >> That you know, the way you think might not be the way I think or might not be the way Ingred thinks or might not be the way Steve thinks. And having all of us together in the same room sometimes generates surprising results. >> Right. Right. Exactly. >> So Josh, do you have any last words of wisdom or semi-wisdom for us? >> I don't know. I'm not the wisest guy in the world. Um I don't know. Uh I think uh you know the world is scary right now for lots and lots of reasons. But um very often what you see in the media is sort of dismal, right? It's like, "Oh gosh, this is just how is this ever going to work?" Um uh and you got to be you got to steal yourself a little bit to walk into it because you see some pretty some pretty scary things. But I think when you get close to what's actually going on, when you move through the media narratives that are designed to alarm so as to engage, >> y >> you find it's actually a little bit more nuanced than that. There's a lot of interesting stuff, a lot of great potential, a lot of scary stuff. Um, but I think uh if there if there's a word of wisdom there, it's don't believe the hype. Look carefully. Try to understand what's going on. Try to engage with the new technology. Don't get beaten into submission and hide. >> Yeah. I guess so. One of the things that I think about based on what you were just saying or that that comes to mind for me is AI is a new technology but we have weathered many new technologies and a lot of times it's not so much that things are better or worse they're different and we've got to be prepared for that differentness. >> Yeah, I think that's right. I you know I just as as a cod to that I was part of a little email thread my my father and uh one of the one of his his friends said well here's how Hal is here now but but that's that's not right it's not it's not that Hal is here right now and it's not that AI is going to take every single job there's so much more beyond that horizon I feel sometimes like with AI I've gone from you know playing uh you know the the cello to being a conductor of an orchestra. >> Yeah. >> Or instead of taking a trip on foot I now have a pocket lejet and I can travel vast different distances. So it amplifies my creativity and my ability to do things in ways that are completely unique. Um, and so there's that flip side and I think that I' I'd love for people to approach it with some of that. >> Great. >> Josh, thanks for coming and talking to us today. >> I think it's been great. >> Yep. Thanks. Thanks.
