Daniel Goleman brought the notion of "EI" to prominence as an alternative to more traditional measures of IQ with his 1995 mega-best-seller Emotional Intelligence.Since the publication of that book, conferences and academic institutes have sprung up dedicated to the idea. EI is taught in public schools, and corporate leaders have adopted it as a new way of thinking about success and leadership. EI, and one's "EIQ," can be an explanation of why some "average" people are incredibly successful, while "geniuses" sometimes fail to live up to their promise.

"Emotional Intelligence, Goleman's highly readable and wide-ranging exploration of the best research available by modern psychologists and educators, provides important insights into the true meaning of intelligence and the qualities it encompasses."

David Perlman, San Francisco Chronicle.
