Unsubstantiated
The book has an interesting hook. It posits a four-square grid of assessing and improving emotional intelligence: self-awareness, other-awareness, self-management, and other-management. They have an on-line assessment that tracks your "progress" (which you can't access from the book if you buy it used and the previous owner accessed the survey) and compares you to others who take the assessment. However, there is no evidence presented that there is a linkage between the assessment and actual outcomes that one would want to achieve (eg, fewer conflicts at work, and better decision outcomes), nor is there any evidence presented that the factors that are included in the assessment are valid and reliable. It does make you more mindful of the emotional environment, but it also wallows in the obvious, along the lines of don't ask your boss about a raise the day his wife leaves him.
