KNOWLEDGE TRANSMISSIBILITY AND PLURALISTIC IGNORANCE: A FIRST STAB

METAPHILOSOPHY, Issue 3 2010
VINCENT F. HENDRICKS
Abstract: Pluralistic ignorance is a nasty informational phenomenon widely studied in social psychology and theoretical economics. It revolves around conditions under which it is "legitimate" for everyone to remain ignorant. In formal epistemology there is enough machinery to model and resolve situations in which pluralistic ignorance may arise. Here is a simple first stab at recovering from pluralistic ignorance by means of knowledge transmissibility. [source]

The Speculum of Ignorance: The Women's Health Movement and Epistemologies of Ignorance

HYPATIA, Issue 3 2006
NANCY TUANAArticle first published online: 9 JAN 200
This essay aims to clarify the value of developing systematic studies of ignorance as a component of any robust theory of knowledge. The author employs feminist efforts to recover and create knowledge of women's bodies in the contemporary women's health movement as a case study for cataloging different types of ignorance and shedding light on the nature of their production. She also helps us understand the ways resistance movements can be a helpful site for understanding how to identify, critique, and transform ignorance. [source]

Two Influential Theories of Ignorance and Philosophy's Interests in Ignoring Them

HYPATIA, Issue 3 2006
SANDRA HARDING
Karl Marx and Sigmund Freud provided powerful accounts of systematic interested ignorance. Fifty years ago, Anglo-American philosophies of science stigmatized Marx's and Freud's analyses as models of irrationality. They remain disvalued today, at a time when virtually all other humanities and social science disciplines have returned to extract valuable insights from them. Here the argument is that there are reasons distinctive to philosophy why such theories were especially disvalued then and why they remain so today. However, there are even better reasons today for philosophy to break from this history and find more fruitful ways to engage with systematic interested ignorance. [source]

Surmounting City Silences: Knowledge Creation and the Design of Urban Democracy in the Everyday Economy

INTERNATIONAL JOURNAL OF URBAN AND REGIONAL RESEARCH, Issue 1 2009
NANCY ETTLINGER
This essay presents segregation as a fundamental, longstanding and widespread problem that impedes democratic urban life and is intelligible from a critical geographic perspective. Ignorance is spatially produced by segregation at multiple scales so as to legitimize and perpetuate silence about problems among marginalized groups. This spatialized understanding explains inequality, problematizes and difference prompts an agenda that forefronts the creation of new social knowledges. The focus here is on the everyday economy as a crucial but commonly overlooked context for developing such knowledges. I re-present a theory of knowledge creation developed for the pursuit of commercial competitiveness and reconfigure it to mesh socio-political and economic goals. A central challenge is to change prevailing discourses by cultivating new practices that entail meaningful interaction among people otherwise segregated. Efficiency becomes a means to social as well as economic ends, as respect and trust grow from collaborative experience among people who might otherwise not interact. Résumé Ce travail présente la ségrégation comme un problème fondamental, persistant et généralisé qui handicape la vie urbaine démocratique et qui peut être appréhendé d'un point de vue critique géographique. L'ignorance est le résultat, sur le plan spatial, d'une ségrégation à plusieurs échelons aux fins de justifier et de perpétuer le silence sur les problèmes qui existent dans les groupes marginalisés. Cette appréhension spatiale explique l'inégalité, tandis que la problématisation de la différence conduit à mettre en évidence la création de nouveaux savoirs sociaux. L'intérêt porte ici sur l'économie du quotidien, considérée comme un contexte essentiel, quoique très souvent négligé, pour le développement de ces savoirs. L'auteur revisite une théorie de la création du savoir élaborée dans le but d'accroître la compétitivité commerciale, et la reconfigure pour qu'elle concorde avec des objectifs sociopolitiques et économiques. L'un des principaux défis consiste à changer la rhétorique dominante en cultivant de nouvelles pratiques qui supposent une interaction porteuse de sens entre des gens par ailleurs ségrégués. L'efficience devient un moyen à des fins sociales et économiques, le respect et la confiance se nourrissant de la collaboration vécue entre des personnes qui, autrement, n'auraient peut-être pas été en relation.

Consumer Welfare and the Loss Induced by Withholding Information: The Case of BSE in Italy

JOURNAL OF AGRICULTURAL ECONOMICS, Issue 1 2004
Mario Mazzocchi
The paper develops a measure of consumer welfare losses associated with withholding information about a possible link between BSE and vCJD. The Cost of Ignorance (COI) is measured by comparing the utility of the informed choice with the utility of the uninformed choice, under conditions of improved information. Unlike previous work that is largely based on a single equation demand model, the measure is obtained retrieving a cost function from a dynamic Almost Ideal Demand System. The estimated perceived loss for Italian consumers due to delayed information ranges from 12 percent to 54 percent of total meat expenditure, depending on the month assumed to embody correct beliefs about the safety level of beef.

Rational Ignorance and Political Morality,

PHILOSOPHY AND PHENOMENOLOGICAL RESEARCH, Issue 1 2006
Guido Pincione
People frequently advance political proposals in the name of a goal while remaining apparently indifferent to the fact that those proposals, if implemented, would frustrate that goal. Theorists of "deliberative democracy" purport to avoid this difficulty by arguing that deliberation is primarily about moral not empirical issues. We reject this view (the moral turn) and propose a method (The Display Test) to check whether a political utterance is best explained by the rational ignorance hypothesis or by the moral turn: the speaker must be prepared to openly acknowledge the bad consequences of his political position. If he is, the position is genuinely moral; if he is not, the position evinces either rational ignorance or posturing. We introduce deontological notions to explain when the moral turn works and when it does not. We discuss and reject possible replies, in particular the view that a moral-political stance insensitive to consequences relies on a distribution of moral responsibility in evildoing. Finally, we show that even the most plausible candidates for the category of purely moral political proposals are best explained by the rational ignorance/posturing hypothesis, if only because enforcing morality gives rise to complex causal issues.

Pluralistic Ignorance and Political Correctness: The Case of Affirmative Action

POLITICAL PSYCHOLOGY, Issue 2 2000
Leaf Van Boven
The pressure to appear politically correct can have important consequences for social life. In particular, the desire to appear politically correct, and to avoid being seen as racist, sexist, or culturally insensitive, can lead people to espouse publicly support for politically correct issues, such as support for affirmative action, despite privately held doubts. Such discrepancies between public behavior and private attitudes, when accompanied by divergent attributions for one's own behavior and the identical behavior of others, can lead to pluralistic ignorance. Two studies investigated pluralistic ignorance with respect to affirmative action among undergraduates. Their survey responses indicate that people overestimate their peers' support for affirmative action and underestimate their peers' opposition to affirmative action, that people's ratings of the political correctness of supporting affirmative action are correlated with their overestimation of support for affirmative action, and that people view their own attitudes toward affirmative action as unique.

Three-Dimensional Pharmacology, a Subject Ranging from Ignorance to Overstatements

BASIC AND CLINICAL PHARMACOLOGY & TOXICOLOGY, Issue 5 2003
Bertil Waldeck
Nevertheless, chiral drugs have been developed and used as racemates, neglecting the fact that they comprise mixtures of two or more compounds which may have quite different pharmacological properties. A very limited access to pure enantiomers in the past has been responsible for this unsatisfactory state of affairs. During the last 20 years, significant achievements have made it possible to perform stereoselective synthesis and analysis. Today, novel chiral drugs are as a rule developed as single enantiomers. Yet, studies of old racaemic drugs are still designed, performed and published without mention of the fact that two or more compounds are involved. In recent years, a number of old racaemic drugs have been re-evaluated and re-introduced into the clinical area as the pure, active enantiomer (the eutomer). While in principle correct, the clinical benefit of this shift from a well established racaemate to a pure enantiomer often seems to be limited and sometimes exaggerated. Racaemic drugs with a deleterious enantiomer that does not contribute to the therapeutic effect (the distomer), may have been sorted out in the safety evaluation process. However, in the future any pharmacological study of racaemic drugs must include the pure enantiomers. This will generate new, valuable information on stereoselectivity in drug action and interaction.

Children's Sensitivity to Their Own Relative Ignorance: Handling of Possibilities Under Epistemic and Physical Uncertainty

CHILD DEVELOPMENT, Issue 6 2006
Elizabeth J. Robinson
Children more frequently specified possibilities correctly when uncertainty resided in the physical world (physical uncertainty) than in their own perspective of ignorance (epistemic uncertainty). In Experiment 1 (N=61), 4- to 6-year-olds marked both doors from which a block might emerge when the outcome was undetermined, but a single door when they knew the block was hidden behind one door. In Experiments 2 (N=30; 5- to 6-year-olds) and 3 (N=80; 5- to 8-year-olds), children placed food in both possible locations when an imaginary pet was yet to occupy one, but in a single location when the pet was already hidden in one. The results have implications for interpretive theory of mind and "curse of knowledge." [source]

Optimizing object classification under ambiguity/ignorance: application to the credit rating problem

INTELLIGENT SYSTEMS IN ACCOUNTING, FINANCE & MANAGEMENT, Issue 2 2005
Malcolm J. Beynon
A nascent technique for object classification is employed to exposit the classification of US banks to their financial strength ratings, presented by the Moody's Investors Services. The classification technique primarily utilized, called CaRBS (classification and ranking belief simplex), allows for the presence of ignorance to be inherent. The modern constrained optimization method, trigonometric differential evolution (TDE), is adopted to configure a CaRBS system. Two different objective functions are considered with TDE to measure the level of optimization achieved, which utilize differently the need to reduce ambiguity and/or ignorance inherently during the optimization process. The appropriateness of the CaRBS system to analyse incomplete data is also highlighted, with no requirement to impute any missing values or remove objects with missing values inherent. Comparative results are also presented using the well-known multivariate discriminant analysis and neural network models. The findings in this study identify a novel dimension to the issue of object classification optimization, with the discernment between the concomitant notions of ambiguity and ignorance.

Doesn't see, doesn't know: is anticipatory looking really related to understanding or belief?

DEVELOPMENTAL SCIENCE, Issue 1 2001
Wendy A. Garnham
Clements and Perner (Cognitive Development, 9 (1994), 377,397) reported that children show understanding of a story character's belief in their anticipatory looking responses before they show this in their answers to test questions. According to Clements and Perner the anticipatory looking responses provide evidence of implicit understanding of belief. This paper examines the possibility that the anticipatory looking measure is indicative of (a) children using a seeing = knowing rule, i.e. children linking not seeing with ignorance rather than a sensitivity to belief, or (b) a tendency to associate the protagonist with the left-hand container. Thirty-two children aged between 2 years 11 months and 4 years were told a false belief story similar to that used in Clements and Perner (1994) except that three containers were used instead of two. The protagonist first looks inside the middle box but then puts the object in the left-hand box. In his absence, a second character moves the object unexpectedly to the right-hand box. If children's anticipatory looking was based on sensitivity to belief then they should have looked clearly to the left-hand box. If it was based on an association bias or sensitivity to the character not knowing then they should have looked equally to the left-hand and middle boxes. The results were consistent with the former prediction suggesting that children's anticipatory looking responses may indeed be governed by an implicit sensitivity to belief. [source]

Precise entities but irredeemably vague concepts?

DIALECTICA, Issue 3 2002
Enrique Romerales
Various arguments have recently been put forward to support the existence of vague or fuzzy objects. Nevertheless, the only possibly compelling argument would support, not the existence of vague objects, but indeterminately existing objects. I argue for the non-existence of any vague entities,either particulars or properties - in the mind-independent world. Even so, many philosophers have claimed that to reduce vagueness to semantics is of no avail, since linguistic vagueness betrays semantic incoherence and this is no less a problem than is ontological incoherence. After spelling out why there are fewer essentially vague concepts than usually thought. I claim that only the linguistic competence of the whole speaking community for each word can draw the sharp boundaries for its concept, even if these are unknowable in practice and still leave a precise range of indetermination. This could explain both the existence of boundaries and our non-removable ignorance of them, fulfilling the intuitions of the epistemic theory of vagueness with the supervaluationist's indeterminacy.

Microbial diversity , insights from population genetics

ENVIRONMENTAL MICROBIOLOGY, Issue 1 2008
Ted H. M. Mes
Summary Although many environmental microbial populations are large and genetically diverse, both the level of diversity and the extent to which it is ecologically relevant remain enigmatic. Because the effective (or long-term) population size, Ne, is one of the parameters that determines population genetic diversity, tests and simulations that assume selectively neutral mutations may help to identify the processes that have shaped microbial diversity. Using ecologically important genes, tests of selective neutrality suggest that adaptive as well as non-adaptive types of selection act and that departure from neutrality may be widespread or restricted to small groups of genotypes. Population genetic simulations using population sizes between 103 and 107 suggest extremely high levels of microbial diversity in environments that sustain large populations. However, census and effective population sizes may differ considerably, and because we know nothing of the evolutionary history of environmental microbial populations, we also have no idea what Ne of environmental populations is. On the one hand, this reflects our ignorance of the microbial world. On the other hand, the tests and simulations illustrate interactions between microbial diversity and microbial population genetics that should inform our thinking in microbial ecology. Because of the different views on microbial diversity across these disciplines, such interactions are crucial if we are to understand the role of genes in microbial communities. [source]

The Assessment of Land Resources: Achievements and New Challenges

GEOGRAPHICAL RESEARCH, Issue 2 2002
Donald A. Davidson
It is surprising that despite all the pleas and policies regarding the development of sustainable land use systems, there is still considerable ignorance regarding the nature and significance of land resources. This paper traces the development and achievements of land evaluation during the 20th century, with particular reference to soils. The most active period was between 1950 and around 1980 with the development of soil and land capability surveys, methodological advances initiated with the FAO Framework for Land Evaluation, and regional land resource assessments. Thus there were considerable achievements in land evaluation by the early 1980s, and subsequently there have been important advances in the subject through the application of GIS, spatial analysis, modelling and fuzzy set algebra. Since the late 1990s there has been a phenomenal rise in interest in soil quality assessment. Considerable debate has focussed on definition, and methods of assessment and monitoring. The latter part of this paper discusses the major challenges to the development and application of land evaluation. The inadequacy of much soil survey data in terms of variables, quality, spatial coverage and scale is emphasised. Also, there is a continuing need to highlight the centrality of land resource issues in any attempt to develop sustainable land use systems. [source]

Rational Irrationality and Simulation in Environmental Politics: The Example of Climate Change

GOVERNMENT AND OPPOSITION, Issue 2 2009
Mathew Humphrey
Do western publics make ,demands' for environmental policy that they have no desire to see enacted? The thesis that they do has been put forward recently by advocates of the ,post-ecologist' paradigm such as Ingolfur Blühdorn. Taking the example of climate change, this article assesses survey results that provide indicative evidence that such ,simulative' demands may exist. I suggest that such demands are, however, best explained through conceptual tools available from game-theoretic and rational-actor models of political behaviour, in particular rational ignorance and rational irrationality, rather than with the societal-level accounts preferred by Blühdorn and others.

Themes of liver transplantation,

HEPATOLOGY, Issue 6 2010
Thomas E. Starzl
Liver transplantation was the product of five interlocking themes. These began in 1958-1959 with canine studies of then theoretical hepatotrophic molecules in portal venous blood (Theme I) and with the contemporaneous parallel development of liver and multivisceral transplant models (Theme II). Further Theme I investigations showed that insulin was the principal, although not the only, portal hepatotrophic factor. In addition to resolving long-standing controversies about the pathophysiology of portacaval shunt, the hepatotrophic studies blazed new trails in the regulation of liver size, function, and regeneration. They also targeted inborn metabolic errors (e.g., familial hyperlipoproteinemia) whose palliation by portal diversion presaged definitive correction with liver replacement. Clinical use of the Theme II transplant models depended on multiple drug immunosuppression (Theme III, Immunology), guided by an empirical algorithm of pattern recognition and therapeutic response. Successful liver replacement was first accomplished in 1967 with azathioprine, prednisone, and antilymphoid globulin. With this regimen, the world's longest surviving liver recipient is now 40 years postoperative. Incremental improvements in survival outcome occurred (Theme IV) when azathioprine was replaced by cyclosporine (1979), which was replaced in turn by tacrolimus (1989). However, the biologic meaning of alloengraftment remained enigmatic until multilineage donor leukocyte microchimerism was discovered in 1992 in long-surviving organ recipients. Seminal mechanisms were then identified (clonal exhaustion-deletion and immune ignorance) that linked organ engraftment and the acquired tolerance of bone marrow transplantation and eventually clarified the relationship of transplantation immunology to the immunology of infections, neoplasms, and autoimmune disorders. With this insight, better strategies of immunosuppression have evolved. As liver and other kinds of organ transplantation became accepted as healthcare standards, the ethical, legal, equity, and the other humanism issues of Theme V have been resolved less conclusively than the medical-scientific problems of Themes I-IV.

Defying the curse of ignorance: perspectives in insect macroecology and conservation biogeography

INSECT CONSERVATION AND DIVERSITY, Issue 3 2010
JOSE ALEXANDRE FELIZOLA DINIZ-FILHO
Abstract., 1. Despite the abundance, richness and ecological importance of insects, distribution patterns remain unknown for most groups, and this creates serious difficulties for the evaluation of macroecological patterns and the underlying drivers. Although the problem is real, we provide an optimistic perspective on insect macroecology and conservation biogeography. 2. Although data for macroecological analysis of insects are not as complete as for many other organisms (e.g., mammals and birds), at least for some insect groups they are equivalent to what existed 10 or 20 years ago for the charismatic megafauna, so initiatives to compile data for broad-scale analyses are feasible. 3. The primary constraint for studies in insect macroecology and conservation biogeography is not (only) poor data; part of the problem arises from a lack of knowledge on how macroecological patterns and processes can be analysed and interpreted. 4. Finally, we present an overview of recent papers using insects as model organisms in macroecology, including richness and diversity gradients, ecogeographical rules, inter-specific relationships, conservation planning and modelling species distributions. Although our list is not exhaustive, it may be useful as guidelines for future research and encourage ICD readers to develop analyses for other insect groups. [source]

Optimizing object classification under ambiguity/ignorance: application to the credit rating problem

Fell-Muir Lecture: Cartilage 2010 , The Known Unknowns

INTERNATIONAL JOURNAL OF EXPERIMENTAL PATHOLOGY, Issue 3 2010
Timothy E. Hardingham
Summary Over the past 40 years there have been giant steps forward in our understanding of cellular and molecular biology that have given us the framework by which to understand tissue organization and tissue function on a range of scales. However, although the progress has been great, the more we have discovered, the more we are aware of what we don't yet know. In this article, I would like to flag up some issues of cartilage biology, function and pathology where we still have significant ignorance. As scientists we all provide contributions to add to the greater understanding of science and progress is on a broad front, but gaps are left where particular difficulty is encountered and in life sciences it is no different. Progress is fast where new knowledge and techniques pave the way, but where study is complex and relevant techniques poorly developed the gaps are left behind. In cartilage research and matrix biology, the gaps can particularly be seen at interfaces between disciplines and where technology development has lagged behind and in the particular challenges of understanding how molecular properties can explain tissue macro properties.

Preference solutions of probability decision making with rim quantifiers

INTERNATIONAL JOURNAL OF INTELLIGENT SYSTEMS, Issue 12 2005
Xinwang Liu
This article extends the quantifier-guided aggregation method to include probabilistic information. A general framework for the preference solution of decision making under an uncertainty problem is proposed, which can include decision making under ignorance and decision making under risk methods as special cases with some specific preference parameters. Almost all the properties, especially the monotonicity property, are kept in this general form. With the generating function representation of the Regular Increasing Monotone (RIM) quantifier, some properties of the RIM quantifier are discussed. A parameterized RIM quantifier to represent the valuation preference for probabilistic decision making is proposed. Then the risk attitude representation method is integrated in this quantifier-guided probabilistic decision making model to make it a general form of decision making under uncertainty. © 2005 Wiley Periodicals, Inc.

On the methods of decision making under uncertainty with probability information

INTERNATIONAL JOURNAL OF INTELLIGENT SYSTEMS, Issue 12 2004
Xinwang Liu
By considering the decision maker's attitude of profit and risk, we propose an alternative selection method that can include the methods of decision making under ignorance and decision making under risk as special cases. An index to measure the decision maker's risk-averse degree is proposed. With a given optimistic level of profit and risk, the evaluation results of the alternatives can be obtained with a geometric ordered weighted average (OWA) operator and a basic defuzzification distribution (BADD) neat OWA operator. Some properties of these two kinds of OWA operator in the problem of decision making under uncertainty are also proposed. © 2004 Wiley Periodicals, Inc. Int J Int Syst 19: 1217,1238, 2004. [source]

Uncertain about Uncertainty: Understanding the Multiple Meanings of a Crucial Concept in International Relations Theory

INTERNATIONAL STUDIES QUARTERLY, Issue 3 2007
Brian C. Rathbun
The force of uncertainty is central to every major research tradition in the study of international relations. Yet uncertainty has multiple meanings, and each paradigm has a somewhat unique understanding of it. More often than not, these meanings are implicit. I argue that realists define uncertainty as fear induced by anarchy and the possibility of predation; rationalists as ignorance (in a nonpejorative sense) endemic to bargaining games of incomplete information and enforcement; cognitivists as the confusion (again nonpejoratively) of decision making in a complex international environment; and constructivists as the indeterminacy of a largely socially constructed world that lacks meaning without norms and identities. I demonstrate how these different understandings are what provide the necessary microfoundations for the paradigms' definitions of learning, their contrasting expectations about signaling, and the functions provided by international organizations. This has conceptual, methodological, and theoretical payoffs. Understanding uncertainty is necessary for grasping the logic of each paradigm, for distinguishing them from each other, and promoting interparadigmatic communication. [source]

The Devil Lies in Details!

JOURNAL OF CONTINGENCIES AND CRISIS MANAGEMENT, Issue 1 2009
How Crises Build up Within Organizations
In this paper, we show that crises result from the combination of two parallel cumulative processes: first, an undercurrent accumulation of organizational imperfections that lay a favourable ground for crises to occur and second, the development of a growing ignorance that keeps managers blind to the presence of these imperfections. The central idea is to demonstrate that organizational imperfections are allowed to build up and grow into vulnerabilities because they are not noticed or taken into consideration. This managerial ignorance is described as a self-nourishing retreat from reality that decreases leaders' ability to pay sufficient attention to the increasing process of accumulation of imperfections and vulnerabilities. A case study in a French chain of supermarket is used to illustrate this process of crisis. [source]

Darkness visible: reflections on underground ecology

JOURNAL OF ECOLOGY, Issue 2 2005
A. H. FITTER
Summary 1Soil science and ecology have developed independently, making it difficult for ecologists to contribute to urgent current debates on the destruction of the global soil resource and its key role in the global carbon cycle. Soils are believed to be exceptionally biodiverse parts of ecosystems, a view confirmed by recent data from the UK Soil Biodiversity Programme at Sourhope, Scotland, where high diversity was a characteristic of small organisms, but not of larger ones. Explaining this difference requires knowledge that we currently lack about the basic biology and biogeography of micro-organisms. 2It seems inherently plausible that the high levels of biological diversity in soil play some part in determining the ability of soils to undertake ecosystem-level processes, such as carbon and mineral cycling. However, we lack conceptual models to address this issue, and debate about the role of biodiversity in ecosystem processes has centred around the concept of functional redundancy, and has consequently been largely semantic. More precise construction of our experimental questions is needed to advance understanding. 3These issues are well illustrated by the fungi that form arbuscular mycorrhizas, the Glomeromycota. This ancient symbiosis of plants and fungi is responsible for phosphate uptake in most land plants, and the phylum is generally held to be species-poor and non-specific, with most members readily colonizing any plant species. Molecular techniques have shown both those assumptions to be unsafe, raising questions about what factors have promoted diversification in these fungi. One source of this genetic diversity may be functional diversity. 4Specificity of the mycorrhizal interaction between plants and fungi would have important ecosystem consequences. One example would be in the control of invasiveness in introduced plant species: surprisingly, naturalized plant species in Britain are disproportionately from mycorrhizal families, suggesting that these fungi may play a role in assisting invasion. 5What emerges from an attempt to relate biodiversity and ecosystem processes in soil is our extraordinary ignorance about the organisms involved. There are fundamental questions that are now answerable with new techniques and sufficient will, such as how biodiverse are natural soils? Do microbes have biogeography? Are there rare or even endangered microbes? [source]

Herding versus Hotelling: Market Entry with Costly Information

JOURNAL OF ECONOMICS & MANAGEMENT STRATEGY, Issue 3 2008
David B. Ridley
Why do businesses such as fast-food restaurants, coffee shops, and hotels cluster? In the classic analysis of Hotelling, firms cluster to attract consumers who have travel costs. We present an alternative model where firms cluster because one firm is free riding on another firm's information about market demand. One consequence of this free riding is that an informed firm might forego a market that it knows to be profitable. Furthermore, an uninformed firm might earn higher profits when research costs are high, because it can credibly commit to ignorance. [source]

Whatever happened to biology?

JOURNAL OF FAMILY THERAPY, Issue 2 2001
Reconnecting family therapy with its evolutionary origins
This article argues for a rapprochement between family therapy and biological science. In spite of the prevailing tendency nowadays to write biology out of the story of family therapy, it has played a central historical and conceptual role in the origin of our discipline. Family therapists may have done themselves and their patients a disservice by distancing themselves from the discipline of biology; ignorance of modern biological ideas may be a serious handicap in the practice of therapy. The gap between contemporary biology and the kind of postmodern thinking currently favoured by many therapists is not as great as it appears, and may be bridged. [source]
