Studies have shown that open-minded dynamics contribute to diverse team effectiveness; however, there are few studies on the factors that influence the impact of open-mindedness. Survey data from 218 members of 47 professionally diverse teams support a significant relationship between open-mindedness and performance. Professional identification and professional salience were found to moderate the relationship with opposing effects. The study data indicate that although open-mindedness provides a context that facilitates the open exchange and discussion of diverse ideas and perspectives in interprofessional teams, this is less influential when members strongly identify with their profession. Conversely, member focus on professional differences enhances the value of team interaction characterised by receptiveness and openness. Analysis confirms a three-way interaction between open-mindedness, professional identification and salience on performance.
