Interpretation of standard psychological test data from culturally diverse assessees for clinical diagnosis and personality description is difficult due to bias and deficits in cultural competence. This chapter presents a process for learning to use credible and available ernie and etic sources for culture-personality information that can increase cultural sensitivity by reducing bias. Ernie sources originate in communities representing one culture, or group within a culture (e.g., Native American Navajos), and are called culture-specific. Etic sources are intended to be universal and hence applicable to all cultural groups. However, many so-called etics, including psychological tests and structured interviews, come directly from our Anglo-American culture and have not been cross-culturally validated for equivalence before being used with other cultural groups. As a consequence, these measures are pseudoetics because their generality has not been established empirically. Personality theories and research may also be pseudoetic because of their Euro-American, male origins and subsequent inappropriate applications to persons from diverse cultural groups.
