Constructions of difference are constitutive for social services. This also includes social research. In our workshop we dealt with the question of how inequality is constructed in a scientific context. Prof. Dr. Isabell Diehm (Institute for General Educational Sciences, Goethe University Frankfurt, Frankfurt am Main) discussed aspects of her research on ethnic differentiation and the relevance of different organisational logics. The workshop was organised to make people more sensitive to differences and to show how they can be dealt with constructively.
