Doesn't discredit what I said. I'm not talking about who is more likely to be gifted or have an IQ off the charts just the generalisations made by some stating iNtuition = intelligent. It doesn’t, there are plenty of stupid iNtuitives and smart Sensors about that any suggestion that someone with intellect = xNxx is presumptuous and adds to the N bias seen in MBTI communities.
The study is interesting though, can’t say I found it too surprising in terms of giftedness.
Ok, ok, not all intuitives are intelligent and not all sensors are dumb. This is true.
However, it's useful to know that if a person has high intelligence, they're more likely to be an intuitive. As a matter of personal anecdote, most of the people I would say are intelligent in my life are certainly intuitives, with the exception of my mother (ISTJ), who has a 120 IQ. Intuitives, almost as a definition, are better apt to understand concepts and put the world together in such a way as to understand it as a whole, while sensors are more apt to understand their personal experiences, which are more limited then a concept or pattern.
Si as a function (which all SJs have as a primary or secondary function) sees the world according to a preconceived notion...by definition this function is generally opposed to learning or adapting, being generally ill-suited (or at least uncomfortable) with learning.
Se as a function (which all SPs have as a primary or secondary function) sees the world according to what sensory input is happening in the moment...by definition this function sees the immediate sensory input, and not how it is connected to a concept or idea (hence why SPs desire a feeling of freedom).
Both Ni and Ne as functions see the world through a connected set of ideas. Ne sees possibility and different points of view, while Ni sees the world through its patterns, understanding complexity with ease. By definition, these functions are more open to possibility, learning, and connecting ideas.
So while N doesn't necessarily mean intelligent, I'd argue that intuition does mean a person is more
comfortable with learning. People do tend to excel at activities they enjoy doing, so it's not a far stretch to make the connection that intuitives, who are generally more comfortable with learning, are more likely to excel at it.
