Most who write about the significance of multiculturalism refer to the changing demographics of the nation and the world. The data are compelling, or should be. The relevancy gap refers to the failure of psychologists to respond to the data—to prepare for the inevitable global changes. Some may rationalize by saying that they do not work cross-culturally, that the clients who seek them out are not unlike themselves. This perspective is flawed. As was noted earlier, all interactions, including treatment, are cross- cultural. Even phenotypic similarity on certain cultural factors (e.g., gender or age) does not negate within-group differences. The phenomenological experience of being female, or of having a disability, or of being a Muslim cannot be presumed. Working effectively with differences should be as important as working effectively with perceived similarities. Cultural competence be- comes more appealing if one sees the personal and professional benefits. Competencies in working with racial differences may facilitate growth and openness in other areas, for example, spiri- tuality or sexual orientation. Diversity research shows that cross- racial interactions between students lead to a higher level of motivation for perspective taking, acceptance of difference and capacity to perceive commonality amid the differences, and faster or better problem solving in diverse groups.
