The need for an integrated theoretical framework for researching the influence of group diversity on performance

Purpose – Investigating diversity presents researchers with a paradox because extremely inconsistent and conflicting findings about the effects of diversity have emerged in this field of study. It has been argued that the theoretical frameworks used have contributed to the paradox. Different and contradictory effects concerning the influence of group diversity can be predicted using these frameworks. The purpose of this paper is to examine the application of the main theoretical frameworks in the context of researching diversity.Design/methodology/approach – The focus of this paper is a critical examination of three theoretical frameworks in the field of diversity research – similarity‐attraction theory, social categorization theory and the information/decision‐making approach. These are commonly applied in researching diversity. The basic elements of each theory, its applications in diversity research and its strengths and limitations are considered.Findings – The discussion suggests that the paradox in ...
