To know or not to know? Genetic ignorance, autonomy and paternalism

This paper examines some arguments which deny the existence of an individual right to remain ignorant about genetic information relating to oneself--often referred to as 'a right to genetic ignorance' or, more generically, as 'a right not to know'. Such arguments fall broadly into two categories: 1) those which accept that individuals have a right to remain ignorant in self-regarding matters, but deny that this right can be extended to genetic ignorance, since such ignorance may be harmful to others, particularly those to whom one is genetically related (the 'harm to others objection') and 2) those which contend that, even if genetic ignorance is only self harming, it is not something to which individuals can rationally or morally claim to have a 'right' at all, since they defend their claims on autonomy-respecting grounds and ignorance is inimical to autonomy (the 'incoherence objection'). I argue that defenders of a right not to know have some plausible responses to the 'harm to others objection', they and their opponents reach an impasse in which both sides are left voicing concerns about the paternalistic implications of the other's point of view. I conclude that defenders of a right not to know would, therefore, advance their position further by analysing it in terms of values other than those of autonomy and rights.     

The Blossoming of Ignorance: Uncertainty,Power and Syncretism Amongst Mongolian Buddhists

Discussions of religious ignorance have arisen contemporaneously with postsocialist frustrations and uncertainties in Ulaanbaatar. My interlocutors responded to discourses of Buddhist ignorance in a number of apparently contradictory ways. Mistrust, religious reverence, ambivalence or fear often coexisted with excitement, exploration and creation. Through frequently describing their own or others' ignorance about Buddhism lay Buddhists indicated that Buddhism, and the renewed possibilities of knowledge or ignorance about Buddhism, was a site of considerable importance. Also indicated was a change in Buddhist epistemologies from the pre-socialist era. This article discusses how talk about religious ignorance in Ulaanbaatar presented itself in a variety of complementary and conflicting ways: as a reflection of anxiety over lost traditions, a source of power and deference, and as a blossoming space for hope and religious enthusiasm.     

The virtues of ignorance

Although ignorance and uncertainty are usually unwelcome feelings, they have unintuitive advantages for both human and non-human animals, which we review here. We begin with the perils of too much information: expertise and knowledge can come with illusions (and delusions) of knowing. We then describe how withholding information can counteract these perils: providing people with less information enables them to judge more precisely what they know and do not know, which in turn enhances long-term memory. Data are presented from a new experiment that illustrates how knowing what we do not know can result in helpful choices and enhanced learning. We conclude by showing that ignorance can be a virtue, as long as it is recognized and rectified.     

It is alive

We need to familiarize ourselves with the facts of evolution, so that we can mount a spirited defense against creationism and the forces of ignorance.     

When peers are not peers and don't know it: The Dunning‐Kruger effect and self‐fulfilling prophecy in peer‐review

The fateful combination of (i) the Dunning‐Kruger effect (ignorance of one's own ignorance) with (ii) the nonlinear dynamics of the echo‐chamber between reviewers and editors fuels a self‐reinforcing collective delusion system that sometimes spirals uncontrollably away from objectivity and truth. Escape from this subconscious meta‐ignorance is a formidable challenge but if achieved will help correct a central deficit of the peer‐review process that stifles innovation and paradigm shifts.     

The right to genetic ignorance confirmed

One of the much debated issues around the evolving human genetics is the question of the right to know versus the right not to know. The core question of this theme is whether an individual has the right to know about her own genetic constitution and further, does she also have the right to remain in ignorance. Within liberal traditions it is usually held that people, if they so wish, have the right to all the knowledge available about themselves. This right is based on the value of autonomy or on the right of self-determination, and it is sometimes partly justified as a countermeasure to the authorities' control over people. I do not wish to deny the right to genetic knowledge (about oneself). I think that its existence is self-evident. The argument I want to put forth in this paper is that in liberal societies we should acknowledge people's right to remain in ignorance as well. The only reason for not doing this would be that grave harm to others would follow if people were allowed to make these seemingly self-regarding decisions. Arguments presented against the right to ignorance are twofold. First there are those arguing against the right to ignorance on the grounds of harm to others, that is, philosophers who do not deny people's right to ignorance in self-related matters but wish to state that genetic ignorance causes harm to others, and this is one of the most commonly accepted reason for restricting people's freedom. The other line of argument flows from the Kantian view that not even merely self-regarding foolishness (in the eyes of others) should be allowed.     

Explaining Spatial Variation in the Recording Effort of Citizen Science Data across Multiple Taxa

The collation of citizen science data in open-access biodiversity databases makes temporally and spatially extensive species’ observation data available to a wide range of users. Such data are an invaluable resource but contain inherent limitations, such as sampling bias in favour of recorder distribution, lack of survey effort assessment, and lack of coverage of the distribution of all organisms. Any technical assessment, monitoring program or scientific research applying citizen science data should therefore include an evaluation of the uncertainty of its results. We use ‘ignorance’ scores, i.e. spatially explicit indices of sampling bias across a study region, to further understand spatial patterns of observation behaviour for 13 reference taxonomic groups. The data is based on voluntary observations made in Sweden between 2000 and 2014. We compared the effect of six geographical variables (elevation, steepness, population density, log population density, road density and footpath density) on the ignorance scores of each group. We found substantial variation among taxonomic groups in the relative importance of different geographic variables for explaining ignorance scores. In general, road access and logged population density were consistently important variables explaining bias in sampling effort, indicating that access at a landscape-scale facilitates voluntary reporting by citizen scientists. Also, small increases in population density can produce a substantial reduction in ignorance score. However the between-taxa variation in the importance of geographic variables for explaining ignorance scores demonstrated that different taxa suffer from different spatial biases. We suggest that conservationists and researchers should use ignorance scores to acknowledge uncertainty in their analyses and conclusions, because they may simultaneously include many correlated variables that are difficult to disentangle.     

Lupus-specific antiribonucleoprotein B cell tolerance in nonautoimmune mice is maintained by differentiation to B-1 and governed by B cell receptor signaling thresholds

Systemic lupus erythematosus is an autoimmune disease characterized by the presence of autoantibodies. One of the unique targets of the immune system in systemic lupus erythematosus is Sm, a ribonucleoprotein present in all cells. To understand the regulation of B cells specific to the Sm Ag in normal mice, we have generated an Ig H chain transgenic mouse (2-12H Tg). 2-12H Tg mice produce B cells specific for the Sm that remain tolerant due to ignorance. We demonstrate here that anti-Sm B cells of 2-12H Tg mice can differentiate into Sm-specific peritoneal B-1 cells that remain tolerant. Differentiation to B-1 and tolerance are governed by the strength of B cell receptor signaling, since manipulations of the B cell receptor coreceptors CD19 and CD22 affect anti-Sm B cell differentiation and autoantibody production. These results suggest a differentiation scheme in which peripheral ignorance to Sm is maintained in mice by the differentiation of anti-Sm B cells to B-1 cells that have increased activation thresholds.     

Induction of antigen-specific effector-phase tolerance following vaccination against a previously ignored B-cell lymphoma

The mechanisms of immune evasion during haematological malignancies are poorly understood. As lymphomas grow in lymphoid organs, it would be expected that if these lymphomas express neo-antigens they should be readily detected by the immune system. To test this assumption, we generated a new non-Hodgkin B-cell lymphoma model expressing the model tumour neo-antigen Ovalbumin (OVA), and analysed the endogenous antigen-specific CD8(+) T-cell response that it elicited in recipient mice. The OVA+ lymphoma cells were eliminated by cytotoxic T lymphocytes (CTL) in mice that had been previously vaccinated against OVA. In contrast, the immune system of na?ve mice ignored the malignant cells even though these continuously expressed and presented OVA on their MHC class I molecules. This state of ignorance could be overcome by therapeutic vaccination, which led to the expansion of endogenous anti-OVA-specific CD8(+) T cells. However, the cytotoxic and interferon-γ secretion capacity of these T cells were impaired. The tumour model that we describe thus reproduces several key aspects of human lymphoma; tumor ignorance can be broken by vaccination but the ensuing immune response remains ineffective. This model can be exploited to further understand the mechanisms of lymphoma immunoevasion and devise effective immunotherapy.     

Power/Knowledge,Power/Ignorance: Forest Fires and the State in Mexico

For over a century the Mexican state has justified its control of forests by claiming that rural people are ignorant and destructive fire setters, in the face of abundant evidence to the contrary. Academic and popular stereotypes of the state have tended to assume that official power and knowledge go hand in hand. In an institutional ethnography ofthe Mexican environment agency, SEMARNAP, I. show how official ignorance is deployed both within and outside state forestry institutions, and how ignorance and complicity may be as important as knowledge in asserting state power. Rather than internalizing official fire discourse, rural people in Mexico learn to mouth polite fictions in their encounters with officials. I argue that the scholarship on governmentality derived from Foucault has uncritically internalized the link between power and knowledge. A closer attention to the production and translation of knowledge within state institutions leads to a more nuancedunderstanding of various forms of obscurity and ignorance which accompany official knowledge claims. This paper is drawn from my fieldwork and archival research in Mexico in the summer of 1998 and between April 2000 and August 2001.     

Anergy and not clonal ignorance determines the fate of B cells that recognize a physiological autoantigen

Autoantibodies to insulin arise spontaneously in the insulin autoimmune syndrome and in type I diabetes. In addition, administration of insulin to individuals without autoimmune disease routinely results in Abs that bind autologous hormone. These observations and findings in transgenic models of tolerance led to an inference that physiological levels of hormones and growth factors, such as insulin, are not sufficient to induce tolerance in B cells, a state termed clonal ignorance. In contrast, we have discovered that virtually all conventional B cells expressing a low affinity anti-insulin transgene interact with endogenous insulin and are effectively silenced for Ig production and for T cell-dependent immune responses. A fraction of transgenic B cells escapes silencing and functions autonomously to produce insulin Abs that may lower fasting blood sugars similar to an insulin autoimmune syndrome. These B cells have characteristics of a B1-like subset and are depleted by hypotonic peritoneal lysis. These findings question the concept of clonal ignorance and show that physiological concentrations of Ag may effectively silence conventional B cells even when the affinity for autoantigen is low. Self-reactivity may arise in the repertoire because of compartmental differences that govern the fate of B cells and not as a result of true clonal ignorance.     

Justus Liebig and the Plant Physiologists

In his book Organic Chemistryin its Application to Agriculture andChemistry, Justus Liebig attacked ``the plantphysiologists' for their support of the humustheory and for their general ignorance ofchemistry. Two leading botanists, MatthiasSchleiden and Hugo von Mohl, responded bysharply criticizing Liebig for his lack ofknowledge of plants and his misrepresentationof the views of plant physiologists. The originand character of this debate can be understoodin part through the temperaments of Liebig andSchleiden, but can be viewed also as a contestfor control between the well-establisheddiscipline of chemistry and a potentialdiscipline of plant physiology that had as yetacquired no stable institutional foundations.     

Uncertainty, ecology, sustainability and policy

Using an Australian focus to explore theoretical and policy issues of wider concern, this article examines linkages between public policy and the science of ecology. This is done within the broader framework of sustainability, emphasizing the problem of decision making in the face of uncertainty. Insights from the ecological, risk, sustainability and policy literatures are used. The sustainability-uncertainty problem is characterized, and the adequacy of existing policy support techniques and approaches noted, particularly the precautionary principle. The problem is further defined using the notion of ignorance. The treatment of ignorance and uncertainty in ecology is discussed. We suggest that the science of ecology has had a limited influence on policy formulation and discuss the basis of this using biodiversity conservation and ecosystem management as examples. We conclude by considering challenges for handling risk, uncertainty and ignorance in ecological science for policy formulation. We emphasize the need for improved communication between the science and policy communities, greater recognition of the limits of quantitative techniques in addressing uncertainty, and contingency planning.     

Conflicting demands on a modern healthcare service: Can Rawlsian justice provide a guiding philosophy for the NHS and other socialized health services?

We explore whether a Rawlsian approach might provide a guiding philosophy for the development of a healthcare system, in particular with regard to resolving tensions between different groups within it. We argue that an approach developed from some of Rawls’ principles – using his ‘veil of ignorance’ and both the ‘difference’ and ‘just savings’ principles which it generates – provides a compelling basis for policy making around certain areas of conflict. We ask what policies might be made if those making them did not know if one was patient, doctor, nurse or manager – in this generation or the next. We first offer a brief summary of Rawls’ approach and how we intend to extrapolate from it. We examine how this adapted Rawlsian framework could be applied to specific examples of conflict within healthcare; we demonstrate how this framework can be used to develop a healthcare service which is both sustainable (in its training and treatment of staff, and in encouraging research and innovation) and open (to protect the powers and opportunities of those using the health service). We conclude that while Rawls’ approach has previously been rejected as a means to address specific healthcare decisions, an adapted veil of ignorance can be a useful tool for the consideration of how a just health service should be constructed and sustained. Turning the theoretical into the practical (and combining Rawls’ thought experiment with Scanlonian contractarianism), managers, doctors, patients, carers and nurses could come together and debate conflicting issues behind a hypothetical veil.     

Sustaining ignorance: the uncertainties of groundwater and its extraction in the Salar de Atacama,northern Chile

The extraction of groundwater and the regulation of its use in many parts of the world have been found to present a particular kind of problem. A contest involving mining companies, an ‘impacted’ community, and the state arising from groundwater and its extraction in the Salar de Atacama, northern Chile, provides a stark example. What marks the case are the many uncertainties about underground water and the quantities extracted. This article argues that uncertainty characterizes conditions of ‘late industrialism’ and that corporate practice that sustains ignorance is a form of powerful agency that in turn maintains the conditions for potentially harmful extractive activity. Critically engaging with the proposition that water may act in the relational process of unknowing contributes to the analysis of how corporate practice may sustain ignorance. This also suggests that alternative political responses to uncertainty are possible.     

Science or alchemy?

Hyperbole has become a common and accepted practice in science nowadays. We sell our results, we hide our ignorance and we use stock terms that gain spurious weight through repeated use. I illustrate from the field of developmental genetics.     

How enzymes adapt: lessons from directed evolution

Enzymes that are adapted to widely different temperature niches are being used to investigate the molecular basis of protein stability and enzyme function. However, natural evolution is complex: random noise, historical accidents and ignorance of the selection pressures at work during adaptation all cloud comparative studies. Here, we review how adaptation in the laboratory by directed evolution can complement studies of natural enzymes in the effort to understand stability and function. Laboratory evolution experiments can attempt to mimic natural evolution and identify different adaptive mechanisms. However, laboratory evolution might make its biggest contribution in explorations of nonnatural functions, by allowing us to distinguish the properties nutured by evolution from those dictated by the laws of physical chemistry.     

The problem of problems

Problems of generating and evaluating problems are discussed and the subjective nature of these processes highlighted. Criteria for problem evaluation are presented as a means to minimize this subjectivity. Areas of continuing ignorance concerning problem generation and evaluation are defined and suggestions made for investigating them.     

Botanical source-areas for some oriental spices

Whether by direct intent or as the result of ignorance, the source-areas for many of the most common spices were unfamiliar to Europe before 1500. Modern botanical knowledge has clarified this uncertainty in the case of most spices, and today it is possible to use this knowledge in the interpretation of the historical record.
