The Limits of Big Data For Social Engineering 95

An anonymous reader writes "In his new book, Social Physics, MIT data scientist Alex 'Sandy' Pentland argues that by analyzing data from smartphones, social media, and credit-card systems, we'll soon be able to have a mathematical understanding of 'the basic mechanisms of social interactions.' Social scientists will be able to understand and predict the interactions of people the way physicists understand and predict the interactions of objects. That will, in turn, enable governments and businesses to create incentive systems to 'tune' people's behavior, making society more productive and creative. In a review of Pentland's book in Technology Review, Nicholas Carr argues that such data-based social engineering 'will tend to perpetuate existing social structures and dynamics' and 'encourage us to optimize the status quo rather than challenge it.' Carr writes, 'Defining social relations as a pattern of stimulus and response makes the math easier, but it ignores the deep, structural sources of social ills. Pentland may be right that our behavior is determined largely by social norms and the influences of our peers, but what he fails to see is that those norms and influences are themselves shaped by history, politics, and economics, not to mention power and prejudice.'"

    What could possibly go wrong?

    • Similar in a fashion to this story....

      Some geographers tried to use the math model that describes the migration of particles between atoms to try to describe population migrations between population centers. This (if I recall) was called the Gravity Model. And it was a huge attempt to make the softer sciences a bit harder by 'mathing them up'. Beyond that, it was trying to shoe-horn the data to fit the theory.

      It failed and fell into just disrepute.

        Bah. They already can. "Person interacts gravitationally with other masses - check." :)

        But seriously, the problem with this notion is that (a) 7ish billion 'particles' is a really small universe. (b) an individual person is more complex than any elemental particle or even atom. Some molecules may get there, but then we're well out of physics and into chemistry... and predicting the full behavior of one complex molecule is still out of reach (see folding problems), much less the interactions of two arbitrary

    "Social scientists will be able to understand and predict the interactions of people the way physicists understand and predict the interactions of objects."

    Many of us technical types would love for this line of inquiry to be fruitful. But to have a 'physics of people' you have to know the values of all the parameters needed to specify the current state of a person and you need to know all interactions of that person with the rest of the universe. Phrased like that you can see how ludicrous it is to dream of using the methods of physics for social science. Physics works because the fundamental constituents of the universe happen to be only a small number of particles whose interactions are amazingly simple. For example all electrons are exactly identical and interact via only 3 forces (with some uncertainties about effects on scales larger than galaxies and energies higher than trillions of electron volts). The hope for a theory of sociology is a false hope. The hope for a useful phenomenology might be more reasonable and big data can help.

    • Psychology will never be as simple or predictable as Newtonian physics. On the other hand, the fact that "big data" is driven primarily by market forces (in particular, targeted marketing and automated trading) seem to give credence to the concept that information can be used to narrow probabilities somewhat. (Perhaps this is what you mean by "useful phenomenology"?)

        The irony is that at a deeper level it's utterly unpredictable what and when a single particle will do in physics. Take a lump of uranium -- it's easy to predict when how much of it will have decayed to lead. It works all the time, always the same. But look at a single uranium atom and there's no way to predict when it will decay. It may be the next second or in a thousand years. All you have is probabilities but these work out into cold, hard predictable facts if what you're dealing with is a lump large enough.

        Psychology works very similar. You can't predict what an individual person will do, but look at enough of them and you'll be able to predict what will happen if you have good enough data. YOU may have "free will" and the freedom to do what you want but as a mass we may still follow strict laws, like everything else in nature.

        You may feel insulted by that or you may see such things as great tools for better understanding of social dynamics.

        • Except in Physics, ALL particles will follow the same basic laws and behavior over time. People are more complex systems and don't follow the same behavior. A lot of people often don't even follow sensible behavior. But those are the easiest to manipulate.

      Not to mention that the fundamental model they are using to try to predict people's behavior is that they will mimic others. This yields a static model of human behavior in which all human behavior would naturally collapse into a homogeneous pattern of behavior (everyone trying to behave like everyone else).

      Anyone who has observed human behavior or studied history knows this is not the case. People naturally fragment into groups and then oppose the ideas of those from other groups. Ideals morph and chang

    seem to me to be two separate things. Statistics tells you what happens when. Understanding tells you why things happen when they do. Statistics can give you data, but not reasons. Understanding requires both. Even with all the data in the world, we're still going to need some kind of interpretative framework to make sense of it all, and creating that framework is the one thing Big Data doesn't make easier.

    What are they going to do when they find out it doesn't work for smart people or people who make conscious decisions to alter their behavior based on their own research? They will just be ignored as outliers because they don't fit in to the statistical modeling. How does the machine learning algorithm model a learning human unless it knows where they're going before they do? What if people inside the model start computing social interactions based on a different model? Do we prohibit these people from evolving their behavior because they don't live inside the machine's conception of how they should act?

    Since social scientists are completely unable to quantify anything in their field of study, I somehow doubt that they will ever come anywhere close to doing "real" science in the way that physicists can: with their "laws", measurements and equations.

      Physicists can, for example, tell you how fast a given object will accelerate when a force is applied to it.

      Social scientists cannot tell you how each individual person will respond to an incentive, but they can tell you roughly how a certain percentage of a population will respond; knowing that is enough to influence the behavior of a group of people.

    • by joh ( 27088 )

      Statistics works the same with people as with atoms and this is real science. Individuals may be hard to quantify, but a mass of people certainly is. That's the reason for the fact that with a small random sample you get reliable data about the population. The fact that YOU may not be part of that sample just is irrelevant since what you do is mostly irrelevant (or only relevant with a very small probability).

      In physics this is exactly the same: You can't make any predictions when it comes to individual par

    ... typically think they can predict individual events from statistics. That is not how it works. Statistics lets you predict statistical things, e.g. how the average of, say, 1000 people will react given a specific situation, when you have an observation how the average of 1000 other people reacted to that situation, but only if the selection was random and there are not many possible reactions. It tells you exactly nothing about how a specific individual will react.

    I'm getting my Ph.D. in behavioral and institutional economics, so this is right up my ally. Carr's response, that "defining social relations as a pattern of stimulus and response makes the math easier" but misses the deeper structure is dead on, but it's more than this. Social norms may determine much of our behavioral responses, but norms vary tremendously by the institution from which they come: how your group of friends prefer to treat each other != how other's prefer to treat each other != how strangers are "supposed" to treat each other in NYC != out strangers are supposed to treat each other in a small town. Moreover, while these norms may be highly correlated with your behavioral responses, people select into institutions (friend circles, communities, neighborhoods, etc) to a large degree based off their compatibility with the institutions norms; e.g. think about outcomes of social group formation, from mostly scratch, freshman year of college.

    This all matters for the article's context because the behavioral parameters they estimate only approximate social norm's suggested behavior, but the suggestions ultimately come from those who chose to adhere to that particular set of norms; trying to "tune" people in ways they don't intrinsically want will fail because they'll just reselect or simply ignore the competing suggestions in favor of those authentic to the group into which they selected. If they take into account that all norms are highly idiosyncratic to their parent institution, it may help with better targeting of products, programs, and information, but the targeting will still have to be revised as people revise their norms; an institution will not revise its norms to conform to what an outside entity feels they should be. So, yeah, I don't think catering to the current observed state of the world can keep norms and society from evolving any more than, say, de jure segregation laws catering to status quo racists/-ism can keep people from forming revising their views about the morality of racism, the laws surrounding it, and their behavioral responses to such societal "tuning", especially over years and generations.
