IQ, or the intelligent quotient, is a term that is very well known since the 1920s. In addition to its practical testing application, it invokes thoughts of how smart you are and how fast you can process and reason out complex data to get to the right answer. EQ, or the emotional quotient, is a term that only came into being in the 1990s when Peter Salovey and John D. Mayer coined the term 'Emotional Intelligence' describing it as "a form of social intelligence that involves the ability to monitor one’s own and others’ feelings and emotions, to discriminate among them, and to use this information to guide one’s thinking and action". They determined that individuals who scored higher in the ability to perceive accurately, understand, and appraise others’ emotions were better able to respond to changes in their social environments and build supportive social networks. Many others have researched this space since the 1990s and have come to the same conclusions, pointing to the fact that it is not cognitive intelligence that guarantees business success but emotional intelligence.
