In his 1996 book Emotional Intelligence, author Daniel Goleman suggested that EQ (or emotional intelligence quotient) might actually be more important than IQ. Why? Some psychologists believe that standard measures of intelligence (i.e. IQ scores) are too narrow and do not encompass the full range of human intelligence. Instead, they suggest, the ability to understand and express emotions can play an equal if not even more important role in how people fare in life.
