This collection of 49 readings with extensive background description exposes students to the breadth of theoretical perspectives and issues in the field of medical anthropology. The text provides specific examples and case studies of research as it is applied to a range of health settings: from cross-cultural clinical encounters to cultural analysis of new biomedical technologies to the implementation of programs in global health settings.

Modularity has been the subject of intense debate in the cognitive sciences for more than 2 decades. In some cases, misunderstandings have impeded conceptual progress. Here the authors identify arguments about modularity that either have been abandoned or were never held by proponents of modular views of the mind. The authors review arguments that purport to undermine modularity, with particular attention on cognitive architecture, development, genetics, and evolution. The authors propose that modularity, cleanly defined, provides a useful framework for directing (...) research and resolving debates about individual cognitive systems and the nature of human evolved cognition. Modularity is a fundamental property of living things at every level of organization; it might prove indispensable for understanding the structure of the mind as well. (shrink)

Intent and mitigating circumstances play a central role in moral and legal assessments in large-scale industrialized societies. Al- though these features of moral assessment are widely assumed to be universal, to date, they have only been studied in a narrow range of societies. We show that there is substantial cross-cultural variation among eight traditional small-scale societies (ranging from hunter-gatherer to pastoralist to horticulturalist) and two Western societies (one urban, one rural) in the extent to which intent and mitigating circumstances influence (...) moral judgments. Although participants in all societies took such factors into account to some degree, they did so to very different extents, varying in both the types of considerations taken into account and the types of violations to which such considerations were applied. The particular patterns of assessment characteristic of large-scale industrialized societies may thus reflect relatively recently culturally evolved norms rather than inherent features of human moral judgment.

The standard view is that the Lagrangian and Hamiltonian formulations of classical mechanics are theoretically equivalent. Jill North, however, argues that they are not. In particular, she argues that the state-space of Hamiltonian mechanics has less structure than the state-space of Lagrangian mechanics. I will isolate two arguments that North puts forward for this conclusion and argue that neither yet succeeds. 1 Introduction2 Hamiltonian State-space Has less Structure than Lagrangian State-space2.1 Lagrangian state-space is metrical2.2 Hamiltonian state-space is symplectic2.3 Metric > (...) symplectic3 Hamiltonian State-space Does Not Have Less Structure than Lagrangian State-space3.1 Lagrangian state-space has less than metric structure3.1.1 A potential worry3.1.2 General Lagrangians3.2 Hamiltonian state-space has more than symplectic structure3.2.1 A dual structure on the Hamiltonian state-space3.2.2 Simple Hamiltonians3.3 Comparing Lagrangian and Hamiltonian structures3.3.1 Counting mathematical structure3.3.2 Symplectic and metric structure are incomparable4 An Alternative Argument for LS4.1 The argument for P3*4.2 Symplectic manifold vs. tangent bundle structure4.3 Trying to patch up the argument for P3*5 Interpreting Mathematical Structure5.1 State-space realism5.2 Model isomorphism and theoretical equivalence6 Conclusion.

We consider how cue-reading, sensory-manipulation, and signaling games may initially evolve from ritualized decisions and how more complex games may evolve from simpler games by polymerization, template transfer, and modular composition. Modular composition is a process that combines simpler games into more complex games. Template transfer, a process by which a game is appropriated to a context other than the one in which it initially evolved, is one mechanism for modular composition. And polymerization is a particularly salient example of modular (...) composition where simpler games evolve to form more complex chains. We also consider how the evolution of new capacities by modular composition may be more efficient than evolving those capacities from basic decisions. (shrink)

There is remarkable variety in emotional life. Not all mental states referred to by the same word (e.g., “fear”) look alike, feel alike, or have the same neurophysiological signature. Variability has been observed within individuals over time, across individuals from the same culture, and of course across cultures. In this paper, I outline an approach to understanding the richness and diversity of emotional life. This model, called the conceptual act model, is not only well suited to explaining individual differences in (...) the frequency and quality of emotion, but it also suggests the counter-intuitive view that the variety in emotional life extends past the boundaries of events that are conventionally called “emotion” to other classes of psychological events that people call by different names, such as “cognitions”. As a result, the conceptual act model is a unifying account of the broad variety of mental states that constitute the human mind. (shrink)

Lewis signaling games illustrate how language might evolve from random behavior. The probability of evolving an optimal signaling language is, in part, a function of what learning strategy the agents use. Here we investigate three learning strategies, each of which allows agents to forget old experience. In each case, we find that forgetting increases the probability of evolving an optimal language. It does this by making it less likely that past partial success will continue to reinforce suboptimal practice. The learning (...) strategies considered here show how forgetting past experience can promote learning in the context of games with suboptimal equilibria. (shrink)

Reformed epistemology and cognitive science have remarkably converged on belief in God. Reformed epistemology holds that belief in God is basic—that is, belief in God is a natural, non-inferential belief that is immediately produced by a cognitive faculty. Cognitive science of religion also holds that belief in gods is (often) non-reflectively and instinctively produced—that is, non-inferentially and automatically produced by a cognitive faculty or system. But there are differences. In this paper, we will show some remarkable points of convergence, and (...) a few points of divergence, between Reformed epistemology and the cognitive science of religion. (shrink)

This article considers how a generalized signalling game may self-assemble as the saliences of the agents evolve by reinforcement on those sources of information that in fact lead to successful action. On the present account, generalized signalling games self-assemble even as the agents co-evolve meaningful representations and successful dispositions for using those representations. We will see how reinforcement on successful information sources also provides a mechanism whereby simpler games might compose to form more complex games. Along the way, I consider (...) how an old game might be appropriated to a new context by reinforcement on successful associations between old and new saliences. (shrink)

The present study provides evidence that valence focus and arousal focus are important processes in determining whether a dimensional or a discrete emotion model best captures how people label their affective states. Individuals high in valence focus and low in arousal focus fit a dimensional model better in that they reported more co-occurrences among like-valenced affective states, whereas those lower in valence focus and higher in arousal focus fit a discrete model better in that they reported fewer co-occurrences between like-valenced (...) affective states. Taken together, these findings suggest that one static, nomothetic theory may not accurately describe the subjective affective experience of all individuals. (shrink)

A background assumption in much contemporary political philosophy is that justice is the first virtue of social institutions, taking priority over other values such as beneficence. This assumption is typically treated as a methodological starting point, rather than as following from any particular moral or political theory. In this paper, I challenge this assumption. To frame my discussion, I argue, first, that justice doesn’t in principle override beneficence, and second, that justice doesn’t typically outweigh beneficence, since, in institutional contexts, the (...) stakes of beneficence are often extremely high. While there are various ways one might resist this argument, none challenge the core methodological point that political philosophy should abandon its preoccupation with justice and begin to pay considerably more attention to social beneficence—that is, to beneficence understood as a virtue of social institutions. Along the way, I also highlight areas where focusing on social beneficence would lead political philosophers in new and fruitful directions, and where normative ethicists focused on personal beneficence might scale up their thinking to the institutional case.

Ideal theorists aim to describe the ideally just society. Problem solvers aim to identify concrete changes to actual societies that would make them more just. The relation between these two sorts of theorizing is highly contested. According to the benchmark view, ideal theory is prior to problem solving because a conception of the ideally just society serves as an indispensable benchmark for evaluating societies in terms of how far they deviate from it. In this paper, I clarify the benchmark view, (...) argue that existing criticisms of it are unsuccessful, and develop a novel redundancy objection to the benchmark view and the claim of priority it allegedly entails. I then consider the extent to which ideal theory might facilitate problem solving without being prior to it and argue that it can only play a modest role in this regard. The upshot is that ideal theory is neither required for nor especially relevant to problem solving—but it is not completely irrelevant either. It facilitates problem solving to some limited degree, but no more, say, than theorizing about dystopia. (shrink)

Quine often argued for a simple, untyped system of logic rather than the typed systems that were championed by Russell and Carnap, among others. He claimed that nothing important would be lost by eliminating sorts, and the result would be additional simplicity and elegance. In support of this claim, Quine conjectured that every many-sorted theory is equivalent to a single-sorted theory. We make this conjecture precise, and prove that it is true, at least according to one reasonable notion of theoretical (...) equivalence. Our clarification of Quine’s conjecture, however, exposes the shortcomings of his argument against many-sorted logic. (shrink)

In the past decade the central principles of western feminist theory have been dramatically challenged. many feminists have endorsed post-structuralism's rejection of essentialist theoretical categories, and have added a powerful gender dimension to contemporary critiques of modernity. Earlier 'women' have been radically undermined, and newer concerns with 'difference', 'identity', and 'power' have emerged. Destabilizing Theory explores these developments in a set of specially commissioned essays by feminist theorists. Does this change amount to a real shift within feminist theory, or will (...) feminism's links with an emancipatory modernism reinstate an older political agenda? Can we transcend the common counterposition of equality and difference, or is feminism condemned to argue within the terms of this binary opposition? (shrink)

Shaun Gallagher applies enactivist thinking to a staggeringly wide range of topics in philosophy of mind and cognitive science, even venturing into the realms of biological anthropology. One prominent point Gallagher makes that the holistic approach of enactivism makes it less amenable to scientific investigation than the cognitivist framework it seeks to replace, and should be seen as a “philosophy of nature” rather than a scientific research program. Gallagher also gives truth to the saying that “if you want new ideas, (...) read old books”, showing how the insights of the American pragmatists, particularly Dewey and Mead, offer a variety of resources and tools that can be brought to bear on modern day enactivism. Here, I suggest that the adoption of enactivist thinking would undermine the assumptions of certain scientific positions, requiring their abandonment, rather than simply making it more difficult to conduct research within an enactivist framework. I then discuss how Mead’s work has been used previously as a “pragmatist intervention” to help resolve problems in a related 4E endeavour, Gibson’s ecological psychology, and make a case for the inclusion of radical behaviorism as another pragmatist resource for 4E cognition. I conclude with a plea for further enactivist intervention in studies of comparative cognition. (shrink)

Moral uncertainty and disagreement pervade our lives. Yet we still need to make decisions and act, both individually and politically. So, what should we do? Moral uncertainty theorists provide a theory of what individuals should do when they are uncertain about morality. Public reason liberals provide a theory of how societies should deal with reasonable disagreements about morality. They defend the public justification principle: state action is permissible only if it can be justified to all reasonable people. In this article, (...) we bring these two approaches together. Specifically, we investigate whether considerations of moral uncertainty support public reason liberalism: given moral uncertainty, should we favor public justification? We argue that while moral uncertainty theory cannot vindicate an exceptionless public justification principle, it supports adopting public justification as a pro tanto principle – albeit one that can be overridden when the moral stakes are high. It also provides new answers to some intramural debates among public reason liberals and new responses to some common objections. (shrink)

In his classic “Freedom and Resentment,” P. F. Strawson introduces us to an optimist who believes that our moral responsibility practices are justified by their beneficial consequences. Although many see Strawson as a staunch critic of this consequentialist position, his stated view is only that there is a gap in the optimist’s story where the reactive attitudes should be. In this paper, I fill in the gap. I show how optimism can be suitably modified to reflect an appreciation of the (...) reactive attitudes. And I argue that the ensuing position—on which our moral responsibility practices, taken as a whole, are justified both by their regulation of behavior and by their enabling of interpersonal relationships—provides us not only with a plausible justification of our moral responsibility practices, but also with a fruitful framework for evaluating potential reforms.

Individuals high in valence focus and low in arousal focus fit a dimensional model better in that they reported more co-occurrences among like-valenced affective states, whereas those lower in valence focus and higher in arousal focus fit a discrete model better in that they reported fewer co-occurrences between like-valenced (...) affective states. Taken together, these findings suggest that one static, nomothetic theory may not accurately describe the subjective affective experience of all individuals. (shrink)

In their 2010 book, Biology’s First Law, D. McShea and R. Brandon present a principle that they call ‘‘ZFEL,’’ the zero force evolutionary law. ZFEL says (roughly) that when there are no evolutionary forces acting on a population, the population’s complexity (i.e., how diverse its member organisms are) will increase. Here we develop criticisms of ZFEL and describe a different law of evolution; it says that diversity and complexity do not change when there are no evolutionary causes.

Hobbes believed that the state of nature would be a war of all against all. Locke denied this, but acknowledged that in the absence of government, peace is insecure. In this paper, I analyse both accounts of the state of nature through the lens of classical and experimental game theory, drawing especially on evidence concerning the effects of punishment in public goods games. My analysis suggests that we need government not to keep wicked or relentlessly self-interested individuals in line, but (...) rather to maintain peace among those who disagree about morality.

Ideology critics believe that many bad social practices persist because of ideology, and that critiquing ideology is an effective way to promote social reform. Skeptics draw on game theory to argue that the persistence of such practices is better explained by collective action problems, and that ideology critique is causally inefficacious. In this paper, I reconcile these camps. I show that while game theory can help us identify contexts where ideology critique makes no difference, it also reveals causal mechanisms by (...) which ideology critique can have a significant effect. I then consider some objections and directions for further research. (shrink)

This essay examines the proposal that psychological essentialism results from a history of natural selection acting on human representation and inference systems. It has been argued that the features that distinguish essentialist representational systems are especially well suited for representing natural kinds. If the evolved function of essentialism is to exploit the rich inductive potential of such kinds, then it must be subserved by cognitive mechanisms that carry out at least three distinct functions: identifying these kinds in the environment, constructing (...) essentialized representations of them, and constraining inductive inferences about kinds. Moreover, there are different kinds of kinds, ranging from nonliving substances to biological taxa to within-species kinds such as sex, and the causal processes that render these categories coherent for the purposes of inductive generalization vary. If the evolved function of essentialism is to support inductive generalization under ignorance of true causes, and if kinds of kinds vary in the implicit assumptions that support valid inductive inferences about them, then we expect different, functionally incompatible modes of essentialist thinking for different kinds. In particular, there should be differences in how biological and nonbiological substances, biological taxa, and biological and social role kinds are essentialized. The functional differences between these kinds of essentialism are discussed. (shrink)

We consider the efficacy of various forms of reinforcement learning with punishment in evolving linguistic conventions in the context of Lewis-Skyrms signalling games. We show that the learning strategy of reinforcement with iterative punishment is highly effective at evolving optimal conventions in even complex signalling games. It is also robust and can be easily extended to a self-tuning variety of reinforcement learning. We briefly discuss some of the virtues of reinforcement with iterative punishment and how it may be related to (...) learning in nature. (shrink)

This book has two main tasks: (1) to call attention to the special challenges presented by our experience of affect—all varieties of pleasure and pain—and (2) to show how these challenges can be overcome by an “enrichment approach” that understands affect as the enrichment or deterioration of conscious activity as a whole. This “enrichment approach” draws from Alfred North Whitehead as well as the pragmatists John Dewey and William James, all of whom thought of affect as a fundamental aspect of (...) experience rather than a special class of feelings. It also draws from recent scientific research that suggests that the dynamic repertoire of consciousness can change, effectively expanding and contracting our capacity to feel. Weaving these perspectives together, the book develops a theory that accounts for the peculiar phenomenology of affect and sheds new light on a diverse range of experiences, from everyday pleasures and pains to the special satisfactions of the arts and religious festivity. At the same time, it presents a fresh and distinctively affect-centered perspective on the nature of consciousness. (shrink)

Essays on Longtermism brings together leading scholars to address questions raised by the longtermist approach to ethical issues. The volume addresses the viability of longtermism, the possibility of predicting and control the far future, and the consequences of longtermist thinking on current political and moral problems.

The Social Intelligence or Social Brain Hypothesis is an influential theory that aims to explain the evolution of brain size and cognitive complexity among the primates. This has shaped work in both primate behavioural ecology and comparative psychology in deep and far-reaching ways. Yet, it not only perpetuates many of the conceptual confusions that have plagued psychology since its inception, but amplifies them, generating an overly intellectual view of what it means to be a competent and successful social primate. Here, (...) I present an analysis of the Social Intelligence/Brain hypothesis highlighting how its anthropocentric origins have led us to be held captive by a picture of what social life involves and the kind of mind needed to navigate the social landscape. I go on to consider how experimental work in this vein either does not test what it claims to be testing, or introduces impossible problems regarding animal minds that cannot be solved, but only dissolved. What we need, in other words, is the application of “Wittgenstein's razor” and the reinvention of primatology along his enactivist lines. (shrink)

The present paper shows how one might model Everettian quantum mechanics using hyperfinitely many worlds. A hyperfinite model allows one to consider idealized measurements of observables with continuous-valued spectra where different outcomes are associated with possibly infinitesimal probabilities. One can also prove hyperfinite formulations of Everett’s limiting relative-frequency and randomness properties, theorems he considered central to his formulation of quantum mechanics. Finally, this model provides an intuitive framework in which to consider no-collapse formulations of quantum mechanics more generally.

I argue that silencing (the act of preventing someone from communicating, broadly construed) can be an act of both interpersonal and institutional violence. My argument has two main steps. First, I follow others in analyzing violence as violation of integrity and show that undermining someone’s capacities as a knower can be such a violation. Second, I argue that silencing someone can violate their epistemic capacities in that way. I conclude by exploring when silencing someone might be morally justifiable, even if (...) doing so is an act of violence. (shrink)

This article offers suggestions for categorizing combat-related moral injuries, highlights possible causes of these injuries in veterans, and touches upon broadly-conceived measures to prevent and repair them. The first part identifies three prevailing definitions – lost trust, guilt, and harm to one’s capacity for right action and moral virtue – and argues for an emphasis on the latter. In service of highlighting areas for future empirical research and clinical awareness, the second part outlines possible veteran-related causes associated with these three (...) definitions, including unwarranted distrust of authorities, misapplying the theodicy problem to human acts, undue survivor’s guilt, wars that fail to meet ad bellum criteria, causing permissible collateral damage, and killing combatants without regret and for pleasure. The third part mentions strategies for preventing character harm, and then discusses the cognitive, rehabituative, and psychological aspects of moral repair. (shrink)

A resolution of the quantum measurement problem would require one to explain how it is that we end up with determinate records at the end of our measurements. Metaphysical commitments typically do real work in such an explanation. Indeed, one should not be satisfied with one's metaphysical commitments unless one can provide some account of determinate measurement records. I will explain some of the problems in getting determinate records in relativistic quantum field theory and pay particular attention to the relationship (...) between the measurement problem and a generalized version of Malament's theorem.

Skyrms-Lewis sender-receiver games with invention allow one to model how a simple mathematical language might be invented and become meaningful as its use coevolves with the basic arithmetic competence of primitive mathematical inquirers. Such models provide sufficient conditions for the invention and evolution of a very basic sort of arithmetic language and practice, and, in doing so, provide insight into the nature of a correspondingly basic sort of mathematical knowledge in an evolutionary context. Given traditional philosophical reflections concerning the nature (...) and preconditions of mathematical knowledge, these conditions are strikingly modest. (shrink)

The ability to make inductive inferences is important because without it, generalization of knowledge to new circumstances would be impossible. One context in which such inductive skills are likely to have been important over evolutionary time is encounters with animals. Previous research suggests that children take into account at least two kinds of relationships between animals when making inductive inferences about them: descent relationships, and design relationships. Because descent and design relationships are sometimes orthogonal, making correct inferences about particular traits (...) sometimes requires overlooking one kind of relationship in favor of the other. In this study, I used a base-to-target induction task to examine the use of two inference rules in 5 to 12 year old Shuar children from the Amazon region of Ecuador. The descent rule uses taxonomic relationships when the function of the trait being judged is ambiguous or unknown, and the design rule privileges ecological relationships over taxonomic relationships when the function of the trait is relevant to the ecological category in question. The results show that Shuar children do employ both of these rules, and are able to switch between them for different kinds of traits, as the descent/design mode hypothesis predicts. Children in both the younger age group and the older age group were able to use these rules, but the older children showed a slightly different pattern due to the use of specific acquired knowledge about some of the taxa.

To understand the evolution of imaginative culture, we need to understand its unique affective power. The purpose of this article is to explain our enjoyment of imaginative culture from the standpoint of a distinctive theoretical approach to understanding affect in terms of the dynamic and energetic features of consciousness. This approach builds upon John Dewey’s view of enjoyment as the enrichment of experience, adding perspectives from studies of the dynamics of consciousness and from ecological psychology. Its main thesis is that (...) positive affect is determined by the causal enrichment of experience, which is defined as the differentiated-ness of conscious states. This approach suggests that the affective power of imaginative culture lies in the way it affords experiences of enriched meaning, as exemplified by our enjoyment of highly nuanced emotion in music.

Although Penn et al's incisive critique of comparative cognition is welcomed, their heavily computational and representational account of cognition commits them to a purely internalist view of cognitive processes. This perhaps blinds them to a distributed alternative that raises the possibility that the human cognitive revolution occurred outside the head, and not in it.

This chapter addresses the question of why many cognitive and behavioural scientists still fail to recognize the truth of nativism despite the power of poverty of stimulus arguments. It argues that this is primarily because the domains in which these arguments have hitherto been applied, for example, language or naive physics, are all ones in which the knowledge that children acquire is objectively present in their environment. Thus, the possibility always remains open that children could somehow be acquiring this knowledge (...) from the environment through general learning. In the case of motivation, however, this last bastion of resistance is unavailable, since desires do not serve to represent information that is already present in the environment. The closest thing to a knockdown argument for nativism can therefore be developed in respect of innate motivational systems. (shrink)

Everyone thinks they know who Prince Zuko is and can be. His father, Fire Lord Ozai, and sister, Azula, think him weak, disobedient, and undeserving of the crown. His Uncle Iroh thinks him good, if troubled, but ultimately worthy of his faith. The kids initially think him a villain, but eventually come to see him as a person – neither monster nor saint – someone who can choose to go in a new way. Zuko himself shows great ambivalence between these (...) conflicting stories about who he is, though each one helps to craft his own self-understanding. In this paper, we apply Hilde Lindemann’s narrative account of the self to explore the ways that others “hold” Zuko in one identity or “let him go” from others. According to Lindemann, our personal identities consist of the first- and third-person stories that cluster around significant acts, relationships, and commitments in our lives. Our identities are fundamentally relational, formed by the interaction between our own self-conception and the ways in which others see us. As such, others’ stories can enable or prevent us from imaginatively projecting ourselves into a particular future. This can lead us to becoming trapped in our identities; without the possibility of being perceived differently by others, we might find ourselves unable to try different ways of being or acting. The converse is also true, in that others can open up new possible identities by seeing things in us that we have trouble seeing in ourselves. If others in our moral community see us as wicked, beyond redemption and unable to repair our wrongs, we are held in the role of the villain and might come to live into that role without question. Zuko’s story is a perfect illustration of Jean Harvey’s reminder that, “it is just not true that once a thief, always a thief” and that agents can choose to go in a new way, can choose to change. How does Zuko change? We argue that Zuko’s redemption is enabled by those in his moral community holding him in identities in which he is a good person, capable and deserving of care, friendship, and love. While the identity he has in relation to his father and sister closes down many possible futures, his uncle Iroh in particular persists in holding him in an identity in which he is loved and worthy of love. And in doing so - in holding this space for him - Iroh opens up a way for Zuko to exercise agency and choose to become a different kind of person than the one he thought he was destined to be.

On Bohm's formulation of quantum mechanics particles always have determinate positions and follow continuous trajectories. Bohm's theory, however, requires a postulate that says that particles are initially distributed in a special way: particles are randomly distributed so that the probability of their positions being represented by a point in any regionR in configuration space is equal to the square of the wave-function integrated overR. If the distribution postulate were false, then the theory would generally fail to make the right statistical (...) predictions. Further, if it were false, then there would at least in principle be situations where a particle would approach an eigenstate of having one position but in fact always be somewhere very different. Indeed, we will see how this might happen even if the distribution postulate were true. This will help to show how loose the connection is between the wave-function and the positions of particles in Bohm's theory and what the precise role of the distribution postulate is. Finally, we will briefly consider two attempts to formulate a version of Bohm's theory without the distribution postulate. (shrink)

In order for Bayesian inquiry to count as objective, one might argue that it must lead to a consensus among those who use it and share evidence, but presumably this is not enough. It has been proposed that one should also require that the consensus be reached from very different initial opinions by conditioning only on basic experimental evidence, evidence free from subjective, social, or psychological influence. I will argue here, however, that this notion of objectivity in Bayesian inquiry is (...) too narrow. (shrink)

This special issue brings together a diverse set of cases from Asia with the aim of decentring established historical narratives about science diplomacy. With a critical perspective bringing together the bodies of literature in the fields of the History of Science, Technology and Medicine (STM) and critical Asian Studies, we argue that these cases foreground a geopolitical history with multiple forms of sovereignty – often contested ones – and a range of political institutions and actors that enables us to revisit (...) science diplomacy as a means for understanding the relationship between science and international affairs. In doing so, the articles in this issue consciously eschew the normative ‘centring’ of superpowers or Western imperial powers as the primary actors, focusing instead on the agency and subjectivity of actors within Asia, many of whom were prominent in their respective local contexts. Additionally, we argue that the cases presented here, which examine issues from across science, technology, medicine and the environment, collectively demonstrate the further need for the ‘science’ in ‘science diplomacy’ to be interpreted more broadly, incorporating as it does many aspects of human engagement with the material world.

A popular claim is that social media is a cause of contemporary high levels of political polarization. In this paper, I consider three of the most common kinds of arguments for the thesis. One type lays out a narrative of causes, tracing the causal steps between logging on to social media and later becoming more polarized. Another type uses computer modeling to show how polarized effects can arise from systems that are analogous to use of social media. The final type (...) considers straightforward experimental evidence for the polarizing effect. I reject each of these arguments and explain why they are unconvincing. (shrink)
