... I just noticed that PersonalityCafe lists the ISTP as "The Mechanic."
And here I am on this forum, calling them motorcycle mechanics. And then I'm being taken literally, as if there was no such thing as a metaphor; as if there were no such things as ideas in the mind - and this forum should stop calling the SJ "The Guardian" and the SP "The Artist." We should just stop making up titles for things because it doesn't conform to reality, and you just never know when an ISTP might complain that he rides motorcycles but he doesn't fix them.
It is interesting however to view the conflicts between types: the Sensors who don't like ideas and the Feelers who are afraid of reducing people to letters.
