This article described three heuristics that are employed in making judgements under uncertainty: representativeness, which is usually employed when people are asked to judge the probability that an object or event A belongs to class or process B; availability of instances or scenarios, which is often employed when people are asked to assess the frequency of a class or the plausibility of a particular development; and adjustment from an anchor, which is usually employed in numerical prediction when a relevant value (...) is available. These heuristics are highly economical and usually effective, but they lead to systematic and predictable errors. A better understanding of these heuristics and of the biases to which they lead could improve judgements and decisions in situations of uncertainty. (shrink)

This article addresses the question of what it is that visual depictions of illness portray, particularly images executed by or on behalf of people who have suffered serious illness. It takes up two lines of inquiry, both to do with the work that such pictures might perform. On the one hand, as works of art, there are questions about the form of signification in visual representations of this kind. On the other, as works of illness, there are issues concerning the (...) role of image-making for sufferers bearing witness to their situation. The article examines the issue of what it is to look at pictures of bodies scarred by treatment for serious disease, and follows this into questions about what it is possible and necessary to show in order to render illness experience tangible. By examining, as exemplars, two particular images of sufferers, it is argued that such portrayals work not just through making visible certain objects for scrutiny, but by figuratively instantiating persons so as to produce a `vision of the non-visual'. In this way picturing illness finds its place in what might be called a politics of care. (shrink)
