Does Emotional Intelligence Make a Difference?

In the previous chapter we defined EI and explained why it can be important for organisations. In this chapter we review the debate about the validity of EI and then present findings from studies using the Emotional Intelligence Questionnaire (EIQ)1 that show that EI can make a difference in predicting/explaining performance in many jobs within different organisations. In addition, we show that EIQ does add significant variance when compared to results produced by personality questionnaires.
