Thanks to YouTube and Google video, we have an old style of magician come to the forefront and get more attention than before. These are the Crafters, masters of their art, hours and days devoted to practicing to an insane amount of skill but unwilling to walk into the spotlight. The introverted perfectionists:
Magic by nature is a performer's art. Look on modern TV competition shows or even older ones and see that magicians with personality, charisma and an outgoing persona get more accolades than those with superior skill but less charm.
Why? Because we like to be entertained and won over, not witness a dry demonstration of superior skill. Thus the Crafter having all the great qualities of a true entertainer, sans the extroverted side, find themselves in a quandary. They don't enjoy being out in huge shows where all attention is one themselves but they certainly love the art of magic.
Enter The Technician.
He will practice, practice, and practice more until his skills are honed to utter perfection then seek out those who would appreciate that talent - other magicians.
And thanks to YouTube, Google Video, and others - he can now post movies of his superior skill all over the Internet and join bulletin boards to show it off. Or stand at his local magic chapter's meeting and awe the crowd, getting the social feedback he desires.
Other magicians will eventually see The Technician as "not a real magician" since he doesn't perform shows. But of course he's better skilled than them, and can't quite comprehend why he's not considered legitimate. So he'll either find a show to be in, or create his own show for a smaller crowd.
Like all introverts, they can stand a bunch of people for only a brief amount of time. Long interactions, extended parties lasting hours, or wandering small talk conversations are horrendously boring.
Just my theory, ISTP's in magic. IMHO of course.
