Abstract

Given what we know about the nature of knowledge and scientific work it no longer makes sense to think of scientific knowledge as demarcated from “ordinary” knowledge through its methods or the characteristics of the scientific community. As the social studies of science have shown, boundaries become ambiguous when viewed close up so that science merges with ordinary knowledge. But does this mean that distinctions between knowledge claims rest on nothing more than social conventions, powerful as these might be? The articles in this special issue address this question from a variety of perspectives, while this introduction sets out this broader framework and highlights the themes that unite the individual articles. Our central argument is that although boundary work is difficult, complex, and contingent, it is too important to be left to chance or tradition. We need to rescue expertise from the antiessentialist consensus that there is nothing but attribution.
