2015-05-13 Against Game Theory
People make choices. Often, the outcome depends on choices other people make. What mental steps do people go through when making such choices? Game theory, the most influential model of choice in economics and the social sciences, offers an answer, one based on games of strategy like chess and checkers: the chooser considers the choices that others will make and makes a choice that will lead to a better outcome for the chooser, given all those choices by other people. It is universally established in the social sciences that classical game theory (even when heavily modified) is bad at predicting behavior. But instead of abandoning classical game theory, various social scientists have mounted an ambitious and energetic rescue operation under the name of “behavioral game theory.” Its main tool is to propose systematic deviations from the predictions of game theory, such as deviations that arise from character type. Other deviations purportedly come from cognitive overload or limitations. The fundamental idea of behavioral game theory is that, if we know the deviations, then we can correct our predictions accordingly, and so get it right. There are two problems with this rescue operation, each fatal. (1) For a chooser, contemplating the range of possible deviations, as there are many dozens, actually makes it exponentially harder to calculate a path to an outcome. This makes the theoretical models unsuited to modeling human thought or human behavior in general. (2) Modeling deviations is helpful only if the deviations are consistent, so that scientists (and decision-makers) can make
predictions about future choices on the basis of past choices. But the deviations are not consistent. In general, deviations from classical models are not consistent for any individual from one task to the next or between individuals for the same task. In addition, people’s beliefs are in general not consistent with their choices. Accordingly, there is no available path for constructing a general behavioral game theory. What can replace it? We survey some of the emerging candidates. More.

"What is it that makes humans into forward-looking thinkers, constantly generating new ideas? For decades, the American cognitive scientist, Mark Turner, has been coming up with ways of approaching these questions that have gained him international recognition. As one of the founding fathers of conceptual integration and blending, for example, he has helped explain how humans are able to combine differing, sometimes contradictory thoughts and ideas within a very short time. Researchers in many different fields, from linguistics and literary studies to psychology, politics and artificial intelligence, draw on Mark Turner’s work."
2015-01-22 Attend the Marshack Lecture on The Origin of Mathematical Ideas at UCLA
Why are we so innovative? Where do new ideas come from? Why are human beings so exceptionally good at innovation, leaving other species mentally in the dust? How can we hold on to new ideas once they are formed? This book explores the claim that the human spark, the source of innovation and the origin of ideas, was an advance that occurred in a particular kind of mental operation, which Turner calls “blending.” View the book talk.
2014-04-09. Blending, neural reuse, and frontiers in human neuroscience
“Advanced blending underlies all manifestations of mapping, including metaphor, which is just one more surface product of this species-defining capacity for integrating disparate mental components into new, meaningful wholes. The human brain is a bubble chamber of mental spaces, constantly building new integration networks, and a culture is an even larger bubble chamber. Just like evolution—and neural reuse—, blending is opportunistic: it reuses whatever is functionally suitable, right there and then. As it happens with the natural selection of living organisms, the process of trial and error in conceptual and neural reuse never stops. Through it, minds and cultures select the few integrations that are really useful, anchor them by means of symbolic procedures, and pass them on to the next generation. To become productive habits, both generic templates of conceptual integration and patterns of neural reuse need to find an adequate niche within the general system. In blending as in neural reuse, a given item, once identified as potentially useful, is integrated into the network under construction. If necessary and possible, the item is adjusted for optimization in its new function. If it works, the item is kept in the network, although it still remains available for its older functions. Networks and their components are discarded and entrenched in a dynamic, extremely agile process. Blending, just like neural reuse, is not direct transfer, but the construction of a new whole with old pieces.”

2013-12-01: Challenges to Blending Theory
See more and read the answers
- Challenge (1): Isn’t blending just epiphenomenal, a kind of linear sum over many other processes (counterfactual thinking, metonymy, categorization, metaphor, other “rhetorical” forms of thought, etc.) that already have names? Why lump them together?
- Challenge (2): Everyone has known about blending—the mental combination of old things to get new things—for a long time. So what is new?
- Challenge (3): If blending exists, shouldn't we be able to program it algorithmically? Isn't that how we specify a mental process in science?
- Challenge (4): Where are the quick psychological tests to show us how blending works? Why don’t you put people in the fMRI machine so we can see where and when blending happens and how it works?
2013-11-01: Concepts of Law
Law depends for its existence and practice upon vast concepts that stretch across time, space, causation, and agency. Vast concepts are fundamental from legislation and interpretation to enforcement and adjudication; from weighing evidence to establishing motive and intent; and from imposing fines or sentences to awarding compensation. But all of human thought and memory is just here and now. Forming and understanding vast legal concepts can be difficult, and failures arise in theory and practice when legal concepts fail to meet certain constraints on intelligibility, congeniality, efficiency, and memorability. We present a model of the formation of legal concepts and some constraints on their practical utility. We also suggest a research agenda that may allow us to better understand what sorts of legal concepts work, and which ones we discard and when. More.
2013-06-12: Can We Build Behavioral Game Theory?
Our experimental results show that people do not choose consistently, do not hold consistent beliefs, and do not in general align actions and beliefs. Choices are inconsistent in ways that prevent us from drawing general characterizations of an individual’s choices or beliefs or of the general population's choices and beliefs. A general behavioral game theory seems a distant and, at present, unfulfilled hope. More.
04/19/2013: Mass Murder for the Media: the Breivik Case in Norway
Audiences are increasingly familiar with shocking news reports of multiple murder by a shooter whose motives, actions, and goals seem strange, disproportionate, even unaccountable. The deep, sustained, almost unparalleled media attention is predictable, with elaborate analyses of cause, motive, and goal. Could it be that the attention we are giving these stories is backfiring, and itself becoming a causal factor in triggering these events? We are studying a case of a shooter that suggests that this is a real danger. In July of 2011, Anders Behring Breivik planned and executed a carefully laid out set of strategies that resulted in bombed government buildings, 77 dead, and 319 injured. Leading up to the events, Breivik prepared an elaborate press kit, including a manifesto and a YouTube publicity video. The media coverage predictably opens up a demand for an explanation; Breivik acted to create such a demand in order to fill it with his message. He studied how to increase his media reach by choosing multiple high-profile targets and combining an urban explosion with a lone shooter’s hours-long sustained massacre of innocents. His proactive use of media attention raises ethical questions, not easily answered, about the responsibility of viewers and the media. More.
2013-01-27: What happens when you partner with an android?
Science fiction has explored in many ways the intimate interaction of people with computers. The protagonist in Blade Runner, whose job is to kill replicants, hooks up with one. An acquaintance says to him, "It's too bad she won't live! But then again, who does?" Much of the analysis of human decision-making depends upon notions of how people think about each other. But what happens when the other agent in your interdependent decision-making is a computer? We tested that. It is well known that people routinely deviate from Nash equilibrium in making decisions. "Quantal Response Equilibrium" theories propose that people are boundedly rational; that the more costly the deviation from Nash equilibrium, the rarer the deviation will be; and that two main sources of these deviations are social preferences about other people and lack of certainty about how they will behave. We stripped off those two possible sources by having subjects play against computer algorithms that they understood would choose strictly so as to maximize their own earnings in each local task. Our subjects still often deviated from Nash equilibrium. Moreover, the deviations were different for each and every game. Our preliminary conclusion is that QRE is not useful at predicting human behavior, and is of limited use in explaining human behavior across even a small range of highly similar decisions.

2012-12-12: Oral Poetics and Cognitive Science
From the Conference Announcement: "Conceptual integration is the human capacity to form novel conceptual wholes from separate, often clashing conceptual materials. Grammatical constructions can be seen as conceptual integration templates, giving minimal instructions to perform mappings and integrations across mental spaces (e.g. Fauconnier & Turner 2002: 147-168). Idiomaticity in oral formulaic style functions in the same way, providing minimal cues for the poet and audience to establish the right idiomatic meaning. In general terms, an oral epic song is itself a multi-modal conceptual blend, emergent from four major inputs: verbal, musical, visual and traditional. To build the complex meanings of composition-in-performance, singers and audiences need to integrate all three modalities, plus their instance-based knowledge of the tradition, into a coherent mental simulation."

2012-06-01: The Theory of Minds Within the Theory of Games
Classical rationality as accepted by game theory assumes that a human chooser in a given moment has consistent preferences and beliefs and that actions result consistently from those preferences and beliefs, and moreover that these preferences, beliefs, and actions remain the same across equal choice moments. Since, as is widely found in prior experiments, subjects do not follow the predictions of classical rationality, behavioral game theorists have assumed consistent deviations from classical rationality and assigned to subjects consistent dispositions to account for these deviations — dispositions having to do with risk preference, cognitive abilities, social norms, etc. All of these theories are fundamentally cognitive theories, making claims about how individual human minds work when choosing. All of them are fundamentally wrong in assuming one kind of consistency or another. Or at least, all of the proposals for consistency in belief, preference, and action with which we are aware turn out to be wrong when tested experimentally. More.
2012-05-03: In a Nutshell: How can we have vast ideas in local minds?

2012-01-16: The Mythology of Game Theory
Non-cooperative game theory is at its heart a theory of cognition, specifically a theory of how decisions are made. Game theory's leverage is that we can design different payoffs, settings, player arrays, action possibilities, and information structures, on the view that these differences lead to different strategies, outcomes, and equilibria. It is well-known that, in experimental settings, people do not adopt the predicted strategies, outcomes, and equilibria. The standard response to this mismatch of prediction and observation is to add various psychological axioms to the game-theoretic framework. Regardless of the differing specific proposals and results, game theory uniformly makes certain cognitive assumptions that seem rarely to be acknowledged, much less interrogated. Indeed, it is not widely understood that game theory is essentially a cognitive theory. Here, we interrogate those cognitive assumptions. We do more than reject specific predictions from specific games. More broadly, we reject the underlying cognitive model implicitly assumed by game theory. More.
2011-06-24: A Natural Way to Write
Traditional writing instruction tacitly assumes that writing is a normal human activity requiring no fundamental cognitive work. We begin by acknowledging the fact that writing is utterly alien to the human evolutionary endowment. There is, however, a species-wide, ancient behavior underlying writing. Cognitive scientists call it "joint attention," and we think it is the most sensible and practical place to begin learning to write. Read more on the Princeton University Press Blog.
2011-03-18: David Broooks on Blending and the Social Animal
"Blending: Any child can say 'I am a tiger'—pretend to be a tiger. It seems so elementary. But in fact it is phenomenally complicated to take a concept I and a concept tiger and blend them together. But this is the source of innovation. What Picasso did, for example, was take the concept Western Art and the concept African Masks and blend them together, not only the geometry, but the moral systems entailed in them." —from David Brooks' TED talk.

2011-01-03: Going Cognitive: Tools For Rebuilding the Social Sciences
How human beings interact is the core of social science research, and human interaction is, in turn, based on the nature of the human mind, so it seems natural that someone casting around for ways to improve the social sciences would turn to cognitive science – the science of the human mind. Since the 1980s, attention to social aspects of cognition has picked up sharply within cognitive science. This attention to social interaction is now a mainstay of cognitive science, suffusing all its branches. Social cognitive neuroscience is a thriving field. Research into distributed cognition, joint attention, the social nature of learning, the cultural origins of conceptual systems, social interaction in child development, co-speech gesture, social cognitive aspects of computing, and other topics involving social interaction has brought attention to the social aspects of cognition. Cognitive scientists are already completely sold on the need to consider social phenomena: interdependent decision-making, for example, and the consideration of other minds and their agency. But the reverse is not true: social scientists do not in general take it for granted that understanding cognition, even understanding social cognition, is crucial to what they do. Graduate programs in the social sciences—economics, political science, law, management, anthropology, sociology—provide no formation in the relevant subjects in cognitive science. Research articles in the social sciences are not required to show command of the relevant subjects in cognitive science in order to pass peer review. Here are a few simple tips on how to integrate cognitive science into the social sciences. Read the working paper . . .
2010-11-06: From Babies to Poets
Cristóbal Pagán Cánovas, a Marie Curie postdoctoral fellow working with me at Case, has won the prestigious ENSAYA 2010 prize for his science journalism article, "From Babies to Poets: Conceptual Integration, spatial cognition, and the poetry of emotions" «De bebés a poetas: integración conceptual, cognición espacial y la poesía de las emociones.»
The ENSAYA Teresa Pinillos Prize is awarded by the University of La Rioja, Spain, in collaboration with the Government of La Rioja, the Spanish Psychology Association and the Royal Spanish Chemistry Association. Every two years, the prize distinguishes the best scientific journalism disseminating science and the humanities in the Spanish language, and making the public conscious of the benefits of research for society.
His essay connects the research on conceptual integration with findings by the cognitive psychologist Jean Mandler and her collaborators, on how the conceptual system gets started by building on spatial cognition, during the first months of life. His EU Marie Curie project investigates how the basic spatial schemas studied by Mandler can be connected to other conceptual materials by the human capacity of advanced conceptual integration, and play a role not only in the initial steps of human thoughts, but also in some of the most spectacular products of the imagination, like poetic metaphors with strong affective meaning. The article gives some highlights of the interdisciplinary possibilities of this research, and suggests that very fruitful collaborations between the humanities and the cognitive sciences could arise if we talk more to each other.

2010-04-02: How To Talk
To talk, the trick is to blend a distributed, complicated mental network, one that often ranges far from home, with an at-home scene—like classic joint attention. Then the away-from-home network has an at-home anchor. If you make the blend, and speak from this blend, then the talk becomes intelligible, consistent, coherent, and familiar, even though you are in fact dealing with a diffuse, complex, away-from-home network of ideas and relationships. . . .

2/15/2010: Natural Selection and Human Language
Terry Deacon hits the nail on the head in urging us to reconsider the interaction between natural selection and human language. His emphasis on "long evolution" is apt. His focus on "relaxed selection" "in an artificial niche" is original, potentially seminal. He offers a major extension of the proposals he made in The Symbolic Species‚ which I reviewed favorably when it was first published (see "Poetry for the Newborn Brain").
My disagreement with Deacon is captured in his title: "The Natural Selection of Human Language." . . . More.

Most researchers accept that writing is cultural, in the strong sense: there are cultures even now that do not include writing, and many illiterate human beings. Writing has been present for, it seems, at most 8,000 years, really more like 3,000 years, and literacy as a normal condition has been with us for only some hundreds of years. It can be harder to see that basic mathematical concepts aside from the few numerical operations that we seem to share with many animals (such as subitizing) are in the same category of cultural invention. But now let us take something that is clearly cultural, in the strong sense: surfing. . . . . More.
2009-09-28: Cognitive Limits
Our cognitive limits in thinking about anything are severe. The human brain operates at a basic, local, human scale, except that our capacity for double-scope blending allows us to understand vast conceptual networks by anchoring them in human-scale blends. The indispensability of human-scale blends is a strong constraint on thought. There are many aspects of our thinking about political and economic decision-making that should be universally accepted, such as that a self is variable, and that a self at any moment knows that it is subject to variation and takes defensive and offensive actions against its past and future versions. These basic truths from cognitive science are papered-over by classical economics, which assumes a constant self, in the form of a utility function. But a self is a complicated and dynamic outcome of complicated conceptual integration networks. . . . More.
2009-08-17: The Scope of Human Thought
Biologically, we resemble other animals, but mentally, we leave them in the dust. The scope of human thought is vast. Why are we so different? Animals—including us—live, think, and feel in the here and now. Living, thinking, and feeling are biological events, existing only in the present. When we think about the past or the future, or anything distant or outside the situation we inhabit, the thinking and feeling are not distant—they are right here, right now, present, confined to our local, human-scale situation, conducted through here-and-now biological systems. In this regard, we are like dogs, dolphins, corvids, chimpanzees. A human being may have been alive 10 years ago and may be alive 10 years hence, but our brain activity of 10 years ago or 10 years hence does not exist. The only systems for living, thinking, and feeling that human beings possess are run by their bodies here and now. . . . More.
