Ability Versus Mixed Emotional Intelligence

The split between measuring emotional intelligence as an ability and measuring it as a blend of traits.
What it is
Mayer, Salovey and Caruso (2008) describe one group of researchers who study emotional intelligence as a distinct set of mental abilities and another who study a broader mix of positive traits such as happiness, self-esteem and optimism. A 2015 meta-analysis of self-report measures found strong overlap with self-efficacy, conscientiousness, emotional stability, extraversion and general mental ability, and a negligible link to supervisor-rated performance once that overlap was accounted for.
In effect
In the article on emotional intelligence, it explains why a performance test and a questionnaire cannot be compared directly.
What it does not say
It does not say that either approach is wrong; the two measure different things and their results are read separately.
