Commentators on the R. D. Roberts, M. Zeidner, and G. Matthews (2001) article on the measurement of emotional intelligence (EI) made various pertinent observations that confirm the growing interest in this topic. This rejoinder finds general agreement on some key issues: learning from the history of ability testing, developing more sophisticated structural models of ability, studying emotional abilities across the life span, and establishing predictive and construct validity. However, scoring methods for tests of EI remain problematic. This rejoinder acknowledges recent improvements in convergence between different scoring methods but discusses further difficulties related to (a) neglect of group differences in normative social behaviors, (b) segregation of separate domains of knowledge linked to cognitive and emotional intelligences, (c) potential confounding of competence with learned skills and cultural factors, and (d) lack of specification of adaptive functions of EI. Empirical studies have not yet established that the Multi-Factor Emotional Intelligence Scale and related tests assess a broad EI factor of real-world significance.
