While in the beginning of the environmental debate, conflicts over environmental and technological issues had primarily been understood in terms of ‘‘risk’’, over the past two decades the relevance of ignorance, or nonknowledge, was emphasized. Referring to this shift of attention to nonknowledge the article presents two main findings: first, that in debates on what is not known and how to appraise it different and partly conflicting epistemic cultures of nonknowledge can be discerned and, second, that drawing attention to nonknowledge (...) in technology conflicts results in significant institutional effects and new constellations of actors in public debates. To illustrate and substantiate this political dynamics of nonknowledge we draw upon examples from the areas of agri-biotechnology and mobile phoning. In a first step, we develop in greater detail the concept of scientific cultures of nonknowledge and identify three such cultures involved in the social conflicts within the two areas. Subsequently, we analyze the specific dynamics of the politicisation of nonknowledge looking at the variety of actors involved and the pluralisation of perceptions and evaluations of what is not known. Then, we point out some of the institutional reactions to the political and cultural dynamics of scientific nonknowledge. We argue that the equal recognition of the diverse cultures of nonknowledge is a key prerequisite for socially legitimate and ‘‘robust’’ decision-making under conditions of politicised scientific nonknowledge.

In this article, I use radiation-shielding maternity clothes as a window to explore motherhood and reproductive uncertainty in urban China. By engaging with literature on scientific uncertainty and intensive mothering, I argue that the scientific uncertainty over the possible negative impact of electromagnetic radiation on pregnancy has led to a situation in which uncertainty is being socially reproduced by experts, markets, and policy makers through different media channels. Middle-class mothers do not fully believe that the cloak is scientifically trustworthy. But (...) under the influence of social networks and the ambient awareness of the reproductive crisis related to environmental pollution and the pressures of modern life, middle-class mothers still choose to wear the clothes for a variable period of pregnancy for psychological feelings of safety. In the end, they choose to cloak their pregnancies but immediately claim their suspicions of the cloak. (shrink)

Studies of protests against mobile phone masts typically concentrate on the potential health risks associated with mobile phones and their masts. Beck’s Risk Society has been particularly influential in informing this debate. This focus on health, however, has merely served to limit the discussion to those concerns legitimated by science conveniently ignoring other disputed issues. In contrast, this article contends that it is necessary to use a wider notion of risk to understand fully how the current political emphasis on active (...) citizenship may have contributed to the protests. It examines how neoliberal governmentality and the move to empower people are in contention with one another. The study draws upon case material from a small village protest group in United Kingdom and argues that much of the tension arises from the encouragement of the public on one hand to become active citizens but on the other to be passive consumers.
