Justin — I agree, this term should be popularized.
The nice thing about the Myers-Briggs personality test is that it places you on the spectrum of each dimension it measures. e.g. you’re not just an Extrovert or Introvert, you’re somewhere in between. Last time I checked I was an INTP, 30% Extro- vs 70% Introvert, 70% Intuitive vs 30% Observing, etc.
