Metaphors in the history of psychology

perpetuate old inequalities in modern dress, rather than bring about "positive diversity", is a reiterated theme of these articles. Another common theme is the inherently problematic nature of a mercantile model invoking "competition" and "customers". The vexed issue of knowledge creation surfaces again in Mel Bartley's investigation of the relationship between research and policy in the case of the unemployment and health debate. Even when research is deemed desirable, what shapes the questions asked, and ignores others? All these essays are stimulating and provocative, and the authors do not shy away from exploring ambiguities in their evaluations of the losses and gains produced by change.
