Abstract Bornstein et al.(1983) employ both argument and evidence to suggest that the Tajfel matrices are an inadequate measure of intergroup behaviour in the social categorization paradigm. These comments reject their criticisms, point out the potentially misleading confoundings between strategies embodied in their own measurement technique, and show that once these confoundings are taken into account, the results of their two experiments are comparable to those normally obtained by the Tajfel matrices. Some misunderstandings about the role of the MD strategy are also corrected.
