Episode 59

Social physics is the idea of using statistics to quantify and manage change in culture. This idea inspired the modern national census, but the difficulty of acquiring data limited what could be accomplished. Today’s technology produces a continuous trail of digital breadcrumbs that allow human behavior to be examined even in complex natural environments. Alexander “Sandy” Pentland, PhD, discusses how large-scale studies can be used to predict and shape a wide range of important common behaviors.

Kim Mills: Hello and welcome to “Speaking of Psychology,” a podcast produced by the American Psychological Association. I'm your host Kim Mills. “Speaking of Psychology” is a podcast for anyone with an interest in the science of psychology. We talked to psychological practitioners and educators about any and every aspect of psychology and its application to the world around us. Dr. Alex Pentland, also known as Sandy, is a professor of Media Arts and Sciences at MIT where he directs the MIT Connection Science and Human Dynamics Labs. He is one of the most cited scientists in the world. Forbes magazine recently named him one of the seven most powerful data scientists in the world. Dr. Pentland’s research focuses on social physics, big data privacy. His research helps people better understand the physics of their social environment and helps individual companies, communities and people to reinvent themselves to be to be safer, more productive more creative. Thank you for speaking with APA today.

Alex Pentland: My pleasure.

Kim Mills: So, let's start with a definition of social physics. What do you mean by that?

Alex Pentland: Well social physics is a word or phrase that's two centuries old. In the beginning of the 1800s alchemy turned into chemistry and in an attempt to clean up its act, natural science turned into physics. And that was this dream of doing something similar with understanding culture, in France in particular that was the idea of using data and statistics to really understand the progression of culture. That spread to England very early on. It's why we have the modern census, which access all sorts of questions. But until just recently it's been very difficult to do very much because it’s been very expensive to get data. You had to have surveys and so forth. Statistics were really not that powerful. In the last decade or so though, using this sort of floodgate of data coming available from cell phones and credit cards and government and everything's digital. That very powerful machine learning methods that let you do statistics that were sort of unimaginable before. And that's social physics--it's the coming together of these new technologies to better understand ourselves.

Kim Mills: So, one of the things that I think you have looked into is electronic interaction among people and what that does for creativity. Can you tell me about what you found in that area?

Alex Pentland: Well we've looked at many different sort of situations, you know, in schools and companies just sort of out in the wild as it were. We do something unusual which is we made your physical interaction along with the electronic interaction. So, we actually build little name badges that keep account of who talked to who, where things like that. Sometimes we ask people to put a little software on their phone so that we can keep track of who actually talked to each other on the telephone or who was nearby each other. And the first thing to notice is that the electronic stuff is not as powerful as the face-to-face stuff. If you're talking about patterns that are predictive of life outcomes, of happiness, of social health, it's the face-to-face stuff that just beats it hands down. That's not to say it's not important. It can sort of bias things in various ways and get people hopped up in various things, but it's the face to face that reinforces and makes it catch. A way to think about that is that you can have a rumor on the internet but it's when you check it out with your neighbors and they go “yeah I heard that too” that it really begins to sort of dig into your mind and you begin to take it seriously.

Kim Mills: Are you finding that because of all of this electronic communication capability that we have today that there's less face-to-face interaction?

Alex Pentland: Well certainly among younger people. You'll have kids and they spend an important hour at a time in their bedrooms, you know, doing various sort of stuff. And then there's a whole sort of culture of keeping kids really really safe. So, there's the free range kids movement in reaction like that. Whereas when you and I were young we sort of went out and did all sorts of stuff – maybe for good and maybe for bad.

Kim Mills: Good thing our parents didn’t know what we were doing.

Alex Pentland: Yeah, well, but it's not actually clear which is right. Certainly, there are things that we did in our generation that weren't good for us or for society. We got ourselves in trouble in various ways. My kids at this age don't experience that of course. They substitute with these online things which are of questionable quality and it tends to be a lot more vicious, actually, in various ways because it has this sense of anonymity. So that's a trade-off. On the other hand, you know, I think teenage pregnancies have gone down.

Kim Mills: So, there is an upside here.

Alex Pentland: So, you know, with a thing I have to worry about or I think I worry about…something I was joke with my wife is that she'd want the kids to be clean and everything to be clean. I said “no no, let them eat dirt” because it's when you have these negative experiences in a sort of controlled way that you build robustness and the ability to deal with these things. And so, I worry that where they call snowflake mess, it comes from the lack of experience in uncomfortable situations. They're not able to deal with it as well as you could and you can fall apart. That means that when you get out in the real world as an adult you're going to have some trauma that you might have, you know, toughened yourself up when you were a kid since it's a trade-off.

Kim Mills: So, you spoke earlier about the availability of vast amounts of data. Right now what kinds of data sets are there out there that we haven't really looked at yet? What can we do with them?

Alex Pentland: Well everybody focuses on Twitter and Facebook and things like that, but those are your public expression. They're not what you really do. And in fact, what you express in the face you put on is often only distantly related to what you actually feel and what you actually do. The sort of datasets that are also out there are increasingly things like location from your cell phone. You know, where are you spending time? Who else is around, or what do you buy from your credit card, or what sort of public transportation do you to have, from Uber or things like that. And then there's all the government data about you. Everything's digital these days. The result is you can get a very, very detailed picture of somebody's actual behavior. Not what they say at their public face but what they actually do in a way that was just inconceivable a decade ago. Most of that data is legally protected. It’s siloed away fairly safely actually as you don't hear a lot about it. But inevitably it will begin to come together in various ways. One of the ways that's important is in research. But we don't really have a sort of picture of human existence, of day-to-day life, of our social health of our communities that we'd like to have. Most of our data comes from little laboratory experiments or questionnaires. It's actually very biased, very limited, very expensive. So, you can imagine that you could make some of this data available in an anonymous, you know, contractually, controlled sort of where you can make meters, you know, sort of happiness of risk, of stress, for communities pretty much in real time. And in fact the experiments we've done show that that's not only possible but it's practical, enough so that in the last couple of years I and some of my compatriots were able to convince the United Nations to put into the sustainable development goals their 15-year goals the notion of actually measuring things like happiness and inequality and sustainability using all of those sort of data sources. Now nobody knows quite what they're gonna have to do to do that because most of those data are held by companies, but you know there's ideas like, you know, making a data tax. Why doesn't the telephone company report sort of aggregate statistics to the government where everybody can see it? That would let us see is this neighborhood a ghetto or is this neighborhood nicely integrated with the rest of society. Turns out integration of a community with society is enormously predictive of outcomes, of whether the kids grow up happy or grow up at all.

Kim Mills: But how could you tell that from phone records? Don't we have other data that tell us those things?

Alex Pentland: Other than phone records, mobility data, like you might get from transportation, or if everybody's using credit cards if you're in a place where that's true. Those are the sources of what people actually do whether they actually spend time with other people or whether they talk to each other within the community. You can go do surveys all you want what you're going to get is “oh yes we talk to everybody”. Sure okay, that's actually not information at all. But when you look at things like the pattern of calls within the neighborhood and outside of the neighborhood, not anybody, I'm not any individual, just a neighborhood, you can predict things like crime rate very accurately. You can predict GDP very accurately. You can predict life expectancy. You can even predict infant mortality with great accuracy by the sort of social connectedness of the community.

Kim Mills: So, our government has a lot of data about us that they are not doing anything with…

Alex Pentland: Yeah that's just recently there's been a hooha about Facebook and all that. Okay, yeah, sure that's all valid, but the other side of the coin is the government has an enormous amount of data about it that's not being used to understand where there are problems. So, an example would be the sort of the Broken Windows policy of 15 years ago I guess now. There was a sort of initial assessment that looked good so people implemented it everywhere in the country. Now the government had lots of data that could have shown that it wasn't working the way people thought but nobody thought to look, they didn't want to release it, it wasn't their job, something. And the result is we got a decade of Broken Windows policy where we never looked at whether it was working. And that you can see today there's a lot of distress about that, you know, people are mad. And the question to me is this: Why doesn't the government make data that it has available for research in a controlled way and safe so there's no questions about privacy, but in a way that allows public debate and scientific evaluation of whether the government and its policies are working? So, I think that the sort of core thing is the government is very happy to not have people know whether the government is working or not. They're not so much into this transparency and accountability thing. So, they just don't really put much effort into releasing the data.

Kim Mills: If you tried asking for some of this data, I mean, how would you unlock it from the government? Do you have to do it with the Freedom of Information Act request, or there are other avenues that you could use?

Alex Pentland: You know that the thing that happens and this happens in health…They also make a defense that's based on privacy. Right, okay. But that's ridiculous. Yeah, you know, those same people that say “oh I can't share this with you because of privacy” take that same data and they give it to commercial subcontractors to optimize their processes, to make more money, to whatever they do. And it works just fine in the sense that you don't get data breaches, you don't get violations of privacy. You take the data, you strip out the identifiers, you give it to somebody for a particular purpose under a contract that makes them liable for screwing up, unlike say Equifax for some. Yeah, so make them liable so they're on the hook and then you monitor them. Works fine. Why don't we do that so that we can check on the government? Yeah, be sort of interesting to know whether some of these policies are really working or not. Recently there was some very brave people within the IRS that made data available to researchers like that and it's remarkable. 30 years of data from the IRS about the outcomes of different minorities across the entire country: what conditions lead to intergenerational mobility. That data just absolutely puts the nail in a lot of theories from both the left and the right. It's interesting because you know they've had that data for generations. So, you stand back and you say “okay so they have this data that could have you know kept millions literally millions maybe tens of millions of lives from jail, other sorts of suffering and they didn't let anybody look at it.” Doesn't that seem wrong? I think it's very wrong. So what this is, is sort of what I'm saying is we need to bring science to the data that we already have and we need to do it in a controlled way that preserves privacy, so forth of course. But we need a lot more accountability and transparency using the data that already exists. And I think that, you know, people are spending too much time yelling about, ah you know we’re all “Facebook is doing whatever” and ignoring the big thing which is the government. Now let's figure out what's actually going on.

Kim Mills: So, what are you working on now? What's next for you in this arena?

Alex Pentland: Well I run a group that does a couple things. We built software and things to help do this sort of release of data, interestingly. So we're funded by like, the government of France in building systems to let them have better accountability for their data, then we do analytics. And the typical thing that we're focused on is what are the conditions that help communities grow, become more innovative, more successful. And those are things it turns out some of the biggest effects are not surprisingly diversity, access and integration with the rest of the community. One of the biggest things that's happened in this country, but also in Europe and elsewhere is a mass segregation based on income. Now there's racial segregation too. I'm not saying that isn't. But the new thing on the block is by income, right? By SES, so the poor folks live over there, the rich, our data show that they do not mix at all except maybe in Walmart. Yeah seriously Walmart, places like that are one of the few places where rich people and poor people actually rub shoulders occasionally. The consequence of course is that they don't talk to each other, they don't understand each other. And a lot of the things we do can be very hurtful to poor people because there's no understanding of the context of what's happening, right? So those are the sorts of things we do. Again, it's interesting who funds that. So, it's people like, you know, European governments, some of the big financial firms are interested in that sort of thing.

Kim Mills: What's different about the European governments that they're interested in this and ours is not?

Alex Pentland: Well the thing that's really different in Europe is that they've taken steps to enforce privacy law. And this is something that was integral too at the very beginning. I ran the discussion in Davos, sort of co-led the discussion in Davos, that led to creation of the privacy laws there. So, they're wrestling with the fact that a lot of business as usual has to stop. It has to change. They have to understand how it is that you can be more respectful about people's control of their own data and still have a working society. And the hope is that by sort of getting ahead of this curve having to do with privacy and so forth that they can set the standard for the world, you know, their companies will do well. Their hope is that companies like Facebook will retreat because of their poor handling of private data and some of their companies in Europe will advance because they're more friendly to people's actual interests.

Kim Mills: This is a little out of left field, but I think I read that some years back you were involved in the development of Google Glass? Yeah a little bit about that because it kind of came in when everybody thought it was gonna be the new thing. It didn't work out too well. Why not?

Alex Pentland: Well some almost 25 years ago now we really broke into the area of wearable computing and tried to build our own Google Glass and stuff. And one of my students, Thad Starner, who's now at Georgia Tech, went on from that experience and actually was one of the technical leads for Google Glass. It wasn't me. I'd like to call myself the Godfather and not the father. I think what it was is it was early to market. It was a good example of the geeks thinking that everybody was a geek. It's a good idea. It’s really cool for you know like surgeon and people building things where you need to see the plans while your hands are…

Kim Mills: Right, right.

Alex Pentland: The thing that they did that was probably the biggest mistake is stick a camera in it at the beginning before people were used to it might have been very successful. People will keep trying it. Eventually we're gonna have little displays in our glasses. Yeah, you know it's coming. It'll be good because it's going to result in not forgetting people's names, not getting lost, all of us somewhat older people are going to have better memories than we might otherwise had, etc.

Kim Mills: Sounds great. Well thank you Dr. Pentland. Thank you for joining us.
