In their contribution Windel and Zimolong compare field studies in in-
company group research with social psychological laboratory findings a
nd discuss the usefulness of the two research approaches for the imple
mentation of in-company group research. In doing so they criticise the
missing practical relevance of social psychological small group resea
rch, particularly in terms of external validity, focus on main effects
and the selection of the independent variables. This article claims t
hat this criticism is irrelevant if the independence of the two resear
ch approaches with their different points of departure, methods and ai
ms is accepted. The demand for the practical usefulness of in-company
group work for basic research in social psychology must be rejected, a
lthough there is necessarily a need for cooperation for purposes of mu
tual animation.
