I find it hilarious that intelligence and personality, two subjects psychologists and neurologists have only a vague understanding of, are getting compared, especially using MBTI and IQ. As useful as MBTI is in opening your mind to understanding how different people work, and as useful as IQ is for ego masturbation, neither are really proven that much more accurate than Cosmo's "Is He A Dud or A Stud?" questionaire.
Here's one quote on one of the "definitions" of intelligence:
"Individuals differ from one another in their ability to understand complex ideas, to adapt effectively to the environment, to learn from experience, to engage in various forms of reasoning, to overcome obstacles by taking thought. Although these individual differences can be substantial, they are never entirely consistent: a given person's intellectual performance will vary on different occasions, in different domains, as judged by different criteria. Concepts of "intelligence" are attempts to clarify and organize this complex set of phenomena. Although considerable clarity has been achieved in some areas, no such conceptualization has yet answered all the important questions and none commands universal assent. Indeed, when two dozen prominent theorists were recently asked to define intelligence, they gave two dozen somewhat different definitions." (From Wikipedia's Intelligence article)
This definition, which is a "proposed consensus idea", even admits that no one agrees on what it means, which is exactly why it, and every other definition, are "proposed" defintions up for review. I don't think anyone will ever agree on a definition. People have to much to win or lose by defining intelligence objectively, especially a bunch of egg-head academics. I've always been bothered by the emphasis on "complex thinking" in intelligence definitions. Complex thinking can murder you in practical reality, which isn't a very smart idea. I like the idea that intelligence shouldn't be measured, but aptitude for success, which I guess would be similar to EQ? Whatever...
By the way, Nemo, this is me after reading your post:
