By saying EQ doesn't exist he's saying there is no "emotional intelligence" trait that determines how good you will be at various emotional/social aspects of life. Instead, testing EQ just looks at those various things and combines the results. There is no reason to believe that, for example, a person who is conscientious will also be agreeable. They are separate traits. A test which tests both (and other things) and combines the results and calls them "EQ" is not useful. Contrast this with intelligence, for which they they test something very specific which you can test even in children, and we know this ability, even though on the surface unrelated to any real-world skill, strongly correlates with how they will perform at many different things later in life. It is an actual trait, not just an average of how good you are at various things.
