EQ isn't rigidly defined, Peterson has been right on that metric, but I think to say it doesn't exist (or to equate it agreeableness) isn't right either. IMO, someone with poor EQ probably also demonstrates poor theory of mind (and I personally put Peterson in this camp).
High EQ, as a skill, is mostly charisma, and can be learned. Dale Carnegie is a good first step, but it also has to be practiced with other people (which is also why I find it hard to develop - you can practice math equations in solitude, but you it's very hard to practice charisma).
