A descriptive norm is a behavioral rule that individuals follow when their empirical expectations of others following the same rule are met. We aim to provide an account of the emergence of descriptive norms by first looking at a simple case, that of the standing ovation. We examine the structure of a standing ovation, and show it can be generalized to describe the emergence of a wide range of descriptive norms.

Investigating the genesis and justification of norms in a theoretical way requires a clear-cut distinction between normative and descriptive discourse. From a philosophical perspective, the descriptive-normative dichotomy can itself be understood either in a descriptive (or ‘reportive’) or in an normative (or ‘stipulative’) way. In the first case such a dichotomy is understood as the factual border between descriptive and normative discourse in a given language; exploring this border is a hermeneutic enterprise. In the other (...) case it is understood as a boundary between descriptive and normative discourse to be implanted in a language which is developed in order to fit certain purposes, in particular theoretical purposes; this implanting procedure is a matter of regimentation. In this paper I will deal shortly with the first question of hermeneutics and then in more detail with the second question of regimentation. In the final part of the paper I will distinguish different types of naturalistic fallacies resulting from disregarding descriptive-normative dichotomies. (shrink)

In this work, we present a mathematical model for the emergence of descriptive norms, where the individual decision problem is formalized with the standard Bayesian belief revision machinery. Previous work on the emergence of descriptive norms has relied on heuristic modeling. In this paper we show that with a Bayesian model we can provide a more general picture of the emergence of norms, which helps to motivate the assumptions made in heuristic models. In our model, (...) the priors formalize the belief that a certain behavior is a regularity. The evidence is provided by other group members’ behavior and the likelihood by their reliability. We implement the model in a series of computer simulations and examine the group-level outcomes. We claim that domain-general belief revision helps explain why we look for regularities in social life in the first place. We argue that it is the disposition to look for regularities and react to them that generates descriptive norms. In our search for rules, we create them. (shrink)

When scientists or science reporters communicate research results to the public, this often involves ethical and epistemic risks. One such risk arises when scientific claims cause cognitive or behavioural changes in the audience that contribute to the self-fulfilment of these claims. I argue that the ethical and epistemic problems that such self-fulfilment effects may pose are much broader and more common than hitherto appreciated. Moreover, these problems are often due to a specific psychological phenomenon that has been neglected in the (...) research on science communication: many people tend to conform to ‘descriptive norms’, that is, norms capturing (perceptions of) what others commonly do, think, or feel. Because of this tendency, science communication may frequently produce significant social harm. I contend that scientists have a responsibility to assess the risk of this potential harm and consider adopting strategies to mitigate it. I introduce one such strategy and argue that its implementation is independently well motivated by the fact that it helps improve scientific accuracy. (shrink)

The behavior of some nightlife-setting patrons would be unacceptable in workplaces or public settings and could cause distress to other patrons. This quantitative study determined 381 young Australian’s descriptive and personal norms regarding four types of sexual behavior. Participants’ personal norms were that these behaviors are wrong, but they reported that the behaviors are common in a nightlife setting. Behaviors such as these could theoretically be prevented by modifying patrons’ descriptive norms with evidence that their (...) beliefs are contrary to individuals’ personal norms of acceptable behavior in nightlife settings.

Some generic generalizations have both a descriptive and a normative reading. The generic sentence “Philosophers care about the truth”, for instance, can be read as describing what philosophers in fact care about, but can also be read as prescribing philosophers to care about the truth. On Leslie’s account, this generic sentence has two readings due to the polysemy of the kind term “philosopher”. In this paper, I first argue against this polysemy account of descriptive/normative generics. In response, a (...) contextualist semantic theory for generic sentences is introduced. Based on this theory, I argue that descriptive/normative generics are contextually underspecified. (shrink)

The Theory of Planned Behavior predicts that a combination of attitudes, perceived norms, and perceived behavioral control predict intentions, and that intentions ultimately predict behavior. Previous studies have found that the TPB can predict students’ engagement in plagiarism. Furthermore, the General Theory of Crime suggests that self-control is particularly important in predicting engagement in unethical behavior such as plagiarism. In Study 1, we incorporated self-control in a TPB model and tested whether norms, attitudes, and self-control predicted intention to (...) plagiarize and plagiarism behavior. The best statistical fit for the path-analytic model was achieved when a direct path from self-control to plagiarism engagement was specified. In Study 2, we added a measure of perceived behavioral control and split the measurement of norms into descriptive and injunctive components. This study found that both self-control and perceived-behavioral control additively contributed to the prediction of plagiarism and the path-analytic model achieved its best fit when direct paths from perceived norms to plagiarism behavior were specified. These studies suggest that setting strong anti-plagiarism norms, such as by the use of honor codes, and seeking to enhance students’ self-control may reduce engagement in plagiarism. (shrink)

Following the implementation of temporary pop-up bike lanes in Berlin, traffic counts by the city administration show an increased number of cyclists. This present paper aims to understand reasons behind this observation. To this end, we focus on the role of mobility-related descriptive social norms as mediators of this effect. Results from one correlational and two experimental online studies are reported. The correlational study confirms the expected association of mobility-related descriptive social norms and self-reported mobility behavior. (...) Moreover, it demonstrates that, as expected, mobility-related descriptive social norms reliably reflect differences in cities’ objective transport structure and mediate the impact of these infrastructural differences on mobility behavior. Results from two online experiments provide additional causal evidence that participants use the visual cues provided by manipulated photos to form their perceived mobility-related descriptive social norms. Furthermore, the second online experiment provides evidence that the combination of infrastructural cues and observable mobility behavior has the strongest impact on perceived mobility-related descriptive social norms.

We have been oversold on the base rate fallacy in probabilistic judgment from an empirical, normative, and methodological standpoint. At the empirical level, a thorough examination of the base rate literature (including the famous lawyer–engineer problem) does not support the conventional wisdom that people routinely ignore base rates. Quite the contrary, the literature shows that base rates are almost always used and that their degree of use depends on task structure and representation. Specifically, base rates play a relatively larger role (...) in tasks where base rates are implicitly learned or can be represented in frequentist terms. Base rates are also used more when they are reliable and relatively more diagnostic than available individuating information. At the normative level, the base rate fallacy should be rejected because few tasks map unambiguously into the narrow framework that is held up as the standard of good decision making. Mechanical applications of Bayes's theorem to identify performance errors are inappropriate when (1) key assumptions of the model are either unchecked or grossly violated, and (2) no attempt is made to identify the decision maker's goals, values, and task assumptions. Methodologically, the current approach is criticized for its failure to consider how the ambiguous, unreliable, and unstable base rates of the real world are and should be used. Where decision makers' assumptions and goals vary, and where performance criteria are complex, the traditional Bayesian standard is insufficient. Even where predictive accuracy is the goal in commonly defined problems, there may be situations (e.g., informationally redundant environments) in which base rates can be ignored with impunity. A more ecologically valid research program is called for. This program should emphasize the development of prescriptive theory in rich, realistic decision environments. (shrink)

According to ‘Excluders’, descriptive uncertainty – but not normative uncertainty – matters to what we ought to do. Recently, several authors have argued that those wishing to treat normative uncertainty differently from descriptive uncertainty face a dependence problem because one's descriptive uncertainty can depend on one's normative uncertainty. The aim of this paper is to determine whether the phenomenon of dependence poses a decisive problem for Excluders. I argue that existing arguments fail to show this, and that, (...) while stronger ones can be found, Excluders can escape them. (shrink)

Although there are many points of continuity, there are also a number of changes in the pedagogical form of the anatomy lecture over the longue durée, over centuries of epistemic change, rather than over years or decades. The article begins with an analysis of the physical and technical arrangements of the early modern anatomy lecture, showing how these present a general underlying similarity compared to those in place today. It then goes on to consider examples of elements of speech and (...) presentation, description and illustration that are used in the biology lecture from the early modern (sixteenth to seventeenth centuries) and late modern (or contemporary) eras. The anatomy lecture thus demonstrates a basic physical and technical continuity in the classroom or theater, whereas the larger epistemic functions in which it is embedded have changed: from a descriptive, discursive function, focusing on individual organs and their physicality, to one that is more integrative, systemic and also performative in both form and content.

Some philosophers think that normative properties are identical to descriptive properties. In this paper, I argue that this entails that it is possible to say which descriptive properties normative properties are identical to. I argue that Frank Jackson's argument to show that this is possible fails, and that the objections to this argument show that it is impossible to say which descriptive properties normative properties are identical to. I conclude that normative properties are not identical to (...) class='Hi'>descriptive properties. I then show that if we combine this conclusion with the conclusion of a different argument that Jackson has given to show that there are no irreducibly normative properties, it follows that there are no normative properties at all.

A model of normative provisions and related axioms represented by using RDF/owl are presented as a contribution to implement the semantic web in the legal domain. In particular, a pattern able to implement the Hohfeldian legal fundamental relations between provisions using OWL-DL expressivity is proposed. Moreover, a query-based approach able to deal with relations between provision instances is described. An example of advanced access and reasoning over provisions using the proposed approach, as well as a prototype architecture of a provision (...) retrieval system, are shown. The main benefit is represented by the ability of the approach to keep the complexity of the problem within a description logic computational tractability. (shrink)

Descriptive realism holds that T is true, while normative realism holds that T is warranted. Descriptive pessimism holds that T is false, while normative pessimism holds that T is unwarranted. We should distinguish between descriptive and normative realism because some arguments against scientific realism require that scientific realism be interpreted as descriptive realism, and because scientific realists can retreat from descriptive to normative realism when descriptive realism is under attack. We should also distinguish between (...) descriptive and normative pessimism because some arguments against scientific pessimism require that it be interpreted as descriptive pessimism, and because scientific pessimists can retreat from descriptive to normative pessimism when descriptive pessimism is under attack. -/- .

Naturalistic Descriptions and Normative-Intentional Interpretations Normative pragmatists about linguistic meaning such as Sellars and Brandom have to explain how norms can be implicit in practices described in purely naturalistic terms. The explanation of implicit norms usually offered in the literature commits pragmatists to equate actions with naturalistic events. Since this is an unacceptable consequence, I propose an alternative explanation of implicit norms that avoids this identification. To do so, one has to treat the normative-intentional concepts such as (...) "norm", "action", "sanction", "belief", "desire" as a holistic system, in the sense that one has to apply all of them to a given naturalistic practice simultaneously. This result might be taken to imply that the pragmatist strategy of explaining the content of assertions and beliefs in terms of norm-governed use is misguided because it presupposes that one can account for the concept "norm" independently of the concept "belief". I argue that this consequence does not follow. (shrink)

Some comments on descriptive and normative aspects of Kuhn's account of science.

Technologies are significant in research not only as instruments for gathering data and analyzing information; they also provide a valuable resource for the development of theory—in terms of what has been called the “tools to theory heuristic.” Focusing on the specific example of the fields of educational psychology and instructional technology and design, this paper begins by describing how the workings of the “tools to theory heuristic” are evident in the metaphors and descriptions of behaviorism, cognitivism, and constructivism. In each (...) of these psychological paradigms, the mind is understood in terms of a contemporaneous technological innovation: as rudimentary circuitry, as computerized data processing, and finally, in terms of information representation and visualization. The paper then argues that in applied disciplines like educational technology and human–computer interaction, technology plays two important but conflicting roles. It first operates heuristically to explain complex mental phenomena; it is then designed and developed explicitly as a tool for facilitating and developing these same complex mental processes. This paper concludes by arguing that this dual role represents an ethical dilemma—a kind of epistemological and practical “conflict of interest” in instructional technology and in related fields of systems and interface design.

Abstract:Most papers in this issue carefully analyze normative and empirical methodologies. I shall argue that (a) there is no purely empirical nor purely normative methodology; (b) some terms escape the division of the normative and descriptive. (c) Most importantly, dialogues such as this one point to a form of integration that allows us to reflect on what it is that each approach presupposes in its study of business ethics. Thus we have made progress in recognizing the importance of each (...) methodology, how each is dependent on the other, and how neither is singularly The Approach to business ethics. (shrink)

This book provides a new and wide-ranging study of law's normativity, examining conceptual, descriptive and empirical dimensions of this perennial philosophical issue. It also contains essays concerned with, among other issues, the relationship between semantic and legal normativity; methodological concerns pertaining to understanding normativity; normativity and legal interpretation; and normativity as it pertains to transnational law. The contributors come not only from the usual Anglo-American and Western European community of legal theorists, but also from Latin American and Eastern European (...) communities, representing a diversity of perspectives and points of view – including essays from both analytic and continental methodologies. With this range of topics, the book will appeal to scholars in transnational law, legal sociology, normative legal philosophy concerned with problems of state legitimacy and practical rationality, as well as those working in general jurisprudence. It comprises a highly important contribution to the study of law's normativity. (shrink)

By a logical theory I mean a formal system together with its semantics, meta-theory, and rules for translating ordinary language into its notation. Logical theories can be used descriptively (for example, to represent particular arguments or to depict the logical form of certain sentences). Here the logician uses the usual methods of empirical science to assess the correctness of his descriptions. However, the most important applications of logical theories are normative, and here, I argue, the epistemology is that of wide (...) reflective equilibrium. The result is that logic not only assesses our inferential practice but also changes it. I tie my discussion to Thagard's views concerning the relationship between psychology and logic, arguing against him that psychology has and should have only a peripheral role in normative (and most descriptive) applications of logic.

The article aims to demonstrate that the nudge theory suffers from three main weaknesses stemming from its theoretical dependence on behavioural economics. The first two weaknesses endanger the paternalistic goal, whereas the third does not justify the libertarian attribute. The first weakness lies in the incomplete realistic characterisation of behavioural economics theory that is the central theoretical pillar of Nudge theory. The second weakness is even more relevant. The normative model of behavioural economics is neoclassical rationality. It can be applied (...) to choices in conditions of risk, when it is possible to forecast the probability of the outcomes of one’s choices. On the contrary the real life problems are inside a complex and uncertain environment. In an uncertain environment the neoclassical algorithms are no longer valid, in that they postulate the knowledge of the probability of the outputs. Thus errors and bias, as observed in behavioural economics, are not such in many instances, but they are instead adaptive and therefore rational responses to the context of decision-making. Therefore nudge theory that pursues the normative paternalistic objective of neutralising the bias and judgement errors discovered by behavioural economics and putting paternalistically the citizen on the right track, is in fact proceeding in the wrong direction. The last weakness concerns an assumption of Nudge theory about the duality of mind. System 1 represents the intuitive mind, while System 2 corresponds to the analytical one. System 1 tends to make decisions quickly and unconsciously, while System 2 follows a slow and conscious process. Biases and judgement errors are mainly generated by System 1. However, System 2 may later intervene to correct them. From this premise, the Nudge theory affirms its libertarian character. In this paper I will argue that the dualism of the mind would not entail the reversibility of some nudges, particularly of default states. In this way the fundamental pillar is weakened to justify the libertarian character of the nudge theory. (shrink)

Frege-Geach worries about embedding and composition have plagued metaethical theories like emotivism, prescriptivism and expressivism. The sharpened point of such criticism has come to focus on whether negation and inconsistency have to be understood in descriptivist terms. Because they reject descriptivism, these theories must offer a non-standard account of the meanings of ethical and normative sentences as well as related semantic facts, such as why certain sentences are inconsistent with each other. This paper fills out such a solution to the (...) negation problems, following some of the original emotivist ideas about the interplay of interests in conversation. We communicate both to share information and coordinate our actions, and we use distinctively normative language like deontic ‘must’ and ‘may’ to negotiate what people are to do. The kinds of disagreement involved in such negotiation can illuminate the issues with negation and inconsistency. This paper outlines a dynamic semantic system in which these ideas can bear fruit, developing the scorekeeping model of conversation. The result is clarification about what Frege-Geach worries can mean for nondescriptive semantics. (shrink)

This work offers a challenge to the orthodox view that descriptive rules are non-normative and passive in their role and usage. It does so by arguing that, although lacking in normativity themselves, descriptive rules can be sources of normativity by way of the normative attitudes that can develop around them. That is, although descriptive rules typically depict how things are, they can also play a role in how things ought to be. In this way, the limited role (...) that this type of rule can play as either a basis for the development of normative reasons, or as explanatory reasons for action is identified and clarified. One desirable outcome of the analysis is a more complete view of what descriptive rules are and how they are utilized by agents. (shrink)

Heather Douglas has helped to set the standard for twenty-first century discussions in philosophy of science on the topics of values in science and science in democracy. Douglas’s work has been part of a movement to bring the question of values in science back to center of the field and to focus especially on policy-relevant science. This first chapter, on the pervasive entanglement of science and values, includes an improved and definitive statement of the argument from inductive risk, which she (...) is single-handedly responsible for rehabilitating and returning to the center of the debate. This statement makes clear the fundamental and absolutely pervasive nature of inductive risk and its import for our understanding of the role of values in science. The chapter also provides a survey of the current field of alternative approaches to ideals for the epistemic role of values in science that is comprehensive and generous, yet critical of each. -/- In these brief comments, I focus on providing an alternative perspective on some conceptual and rhetorical issues in Douglas’s account, specifically dealing with the nature of values and the relation of the descriptive and the normative. This will lead me to somewhat different evaluations of two of the five new ideals for values in science that Douglas canvasses in the chapter. (shrink)

The contributors to this volume engage with issues of normativity within naturalised philosophy. The issues are critical to naturalism as most traditional notions in philosophy, such as knowledge, justification or representation, are said to involve normativity. Some of the contributors pursue the question of the correct place of normativity within a naturalised ontology, with emergentist and eliminativist answers offered on neighbouring pages. Others seek to justify particular norms within a naturalised framework, the more surprising ones including naturalist takes on (...) the a priori and intuitions. Finally, yet others examine concrete examples of the application of norms within particular epistemic endeavours, such as psychopathology and design. The overall picture is that of an intimate engagement with issues of normativity on the part of naturalist philosophers – questioning some of the fundamentals at the same time as they try to work out many of the details.

This paper, like its companion explores some ways in which, on the one hand, normative theorizing about causation and causal reasoning and, on the other, empirical psychological investigations into causal cognition can be mutually illuminating. The topics considered include the connection between causal claims and claims about the outcomes of interventions and the various ways that invariance claims figure in causal judgment.

The problem addressed in this text is the problem of identifying conditions according to which it is possible to distinguish between a descriptive theory and a normative theory. What makes a descriptive theory descriptive and a normative theory normative? Focus is on subjective expected utility theories where it seems open to debate whether the appropriate use is normative or descriptive. My discussion, which takes arguments by Isaac Levi and Hugh Mellor as a point of departure, is (...) mostly negative, showing that there are no obvious distinguishing features of theories qua theories. Rather the theories can be used normatively or descriptively without making them theories of the one kind or the other. I also point to situations in prescriptive decision analysis where one should be observant of in what way theories are used. (shrink)

This paper contains an attempt at constructing a semantic framework for the field of health enhancement. The latter is here conceived as an extremely general category covering the whole area of health care and health promotion. With this framework as a basis I attempt to define the place of medicine within the enterprise of health enhancement. I finally indicate some normative issues for the future, in particular problems and possible developments for medicine as a species of health enhancement.

This paper addresses the potentially interactive effects of descriptive and injunctive norm perceptions on an unethical workplace behavior: counterproductive work behavior perpetration. We draw on the Focus Theory of Normative Conduct and its conceptual distinction between norm types to refine research on this topic. We also test a person-by-environment interaction to determine whether the interactive effects of these norms for CWB are enhanced among employees reporting a stronger need to belong to social groups. In two studies, predictors were (...) assessed in an initial survey and the dependent variable was assessed weeks later. Individuals employed across a range of industries served as participants. In Study 1, descriptive and injunctive norm perceptions of CWB interacted to predict CWB perpetration. This finding was replicated in Study 2. Additionally, Study 2 demonstrated that the interaction between the two norm types was especially strong among individuals high in NTB. Results suggest that to decrease CWB perpetration, organizations may profitably leverage the persuasive effects of “social norms marketing” to alter employee perceptions of the typicality and level of approval for CWBs. This is the first study to demonstrate that both descriptive and injunctive norm perceptions predict CWB perpetration. The demonstrated three-way interaction between the two norm types and NTB advances existing theory regarding the cognitive and motivational mechanisms underlying normative social influence. (shrink)

The aim of this paper is to describe a methodology for revising logical principles in the light of empirical psychological findings. Historical philosophy of science and wide reflective equilibrium in ethics are considered as providing possible models for arguing from the descriptive to the normative. Neither is adequate for the psychology/logic case, and a new model is constructed, employing criteria for evaluating inferential systems. Once we have such criteria, the notion of reflective equilibrium becomes redundant.

Laski has been and remains one of the most erudite and influential of the English liberals—indeed, regardless of which of his books the liberal reads, he finishes it with the feeling that Laski is a force for good in political life. However, for the kind of philosopher who is accustomed to make distinctions between morality, ethics, ideology, and descriptive science, there are certain confusions in Laski's writings that give grounds for criticism of both a theoretical and practical nature.

The past few decades have seen an explosion of research on causal reasoning in philosophy, computer science, and statistics, as well as descriptive work in psychology. In Causation with a Human Face, James Woodward integrates these lines of research and argues for an understanding of how each can inform the other: normative ideas can suggest interesting experiments, while descriptive results can suggest important normative concepts. Woodward's overall framework builds on the interventionist treatment of causation that he developed in (...) Making Things Happen. Normative ideas discussed include proposals about the role of invariant or stable relationships in successful causal reasoning and the notion of proportionality. He argues that these normative ideas are reflected in the causal judgments that people actually make as a descriptive matter. Woodward also discusses the common philosophical practice-particularly salient in philosophical accounts of causation--of appealing to intuitions or judgments about cases in support of philosophical theses. He explores how, properly understood, such appeals are not different in principle from appeals to results from empirical research, and demonstrates how they may serve as a useful source of information about causal cognition.

Recently, researchers and reporters have made a wide range of claims about the distribution, nature, and societal impact of political polarization. Here I offer reasons to believe that, even when they are correct and prima facie merely descriptive, many of these claims have the highly negative side effect of increasing political polarization. This is because of the interplay of two factors that have so far been neglected in the work on political polarization, namely that (1) people have a tendency (...) to conform to descriptive norms (i.e., norms capturing (perceptions of) what others commonly do, think, or feel), and (2) claims about political polarization often convey such norms. Many of these claims thus incline people to behave, cognize, and be affectively disposed in ways that contribute to social division. But there is a silver lining. People’s tendency to conform to descriptive norms also provides the basis for developing new, experimentally testable strategies for counteracting political polarization. I outline three. (shrink)

In this paper, I argue that Constructive Empiricism (CE) is ambiguous between two interpretations: CE as a normative epistemology of science and CE as a descriptive philosophy of science. When they present CE, constructive empiricists write as if CE is supposed to be more than a normative epistemology of science and that it is meant to be responsible to actual scientific practices. However, when they respond to objections, constructive empiricists fall back on a strictly normative interpretation of CE. This (...) ambiguity seems to make CE immune to objections in a rather ad hoc fashion. (shrink)

Abstract.The author gives a short survey of the different methods which have been proposed to deal with the logic of norm sentences on the basis of logical systems of descriptive language: deontic logic, logic of norms as an isomorphism of propositional logic, restriction of logical relations to the propositional content of norm sentences, transformation of norms into sanction sentences, preference interpretation of norm sentences, double interpretation of ought‐sentences and the use of the descriptive interpretation as a (...) tool for establishing the logic of norms, proposition about norms in the place of normative logic, the logic of admissible worlds, postulates addressed to the rational lawgiver and technical ought as a substitute for nor‐mological considerations. A critical analysis of these attempts may prove them inappropriate, but it is not sufficient to prove the impossibility of any method of founding normative logic on systems of a descriptive language. Therefore the author adds a general consideration on the chances of such approaches. (shrink)
