True. I'll edit that in at some point.
But again, I do agree with you in the sense that there's way too much stock in the I and E for overall personality.
An E might be just as, and even more adroit in a field that the introvert specializes in.
Just the same, an introvert might be able to adapt so quickly (for whatever reason) that they learn, in very little time, to trump any the Es who expert and champion those fields.
