This paper examines the knowledges affecting contemporary child welfar
e policy and practice. Using a number of conceptual frameworks, it see
ks to challenge the view of some commentators that a new 'legalism' an
d a putative concern with 'surface form' has accorded formal psycholog
ical knowledge, and hence the 'psy' complex, a diminished and waning s
ignificance. The paper argues that, although there have been significa
nt changes in child welfare practice, rumours of the waning of the 'ps
y' complex have been exaggerated. A detailed analysis of the way the l
aw thinks, and of policy documents and practice guidance reveals both
the complex interdiscursivity of the new 'legalism' and the durability
of psychological and developmentalist forms of thought.
