The first two chapters of this book were concerned with the ways that professional sociologists and psychologists have tried to represent occupational images. In Chapters 3 and 4 we presented our own attempts to model such images with a general metaphor of a continuous space. We identified two major issues in the sociological and psychological literature. The first of these is concerned with the extent to which occupational structure is in some sense ‘real’ and ‘objective’, in such a way that occupational images are derivative of it. We favour the counter-argument to this view, which holds that occupational images are most usefully studied sui generis and that information about these images cannot in general be used to make inferences about any ‘objective’ structure that may exist.
