title: Identity matters to individuals: Group assessment cannot be reduced to collective performance.
abstract: Although we agree that both identification and differentiation play a key role in explaining individual behaviour in groups, we suggest that (1) cohesion and differentiation should be better articulated, (2) the proposal carries implicit value choices that are not necessarily universal, and (3) the success of a group in shaping individual behaviour should refer to the values of individual members.
