I thought it was a serious article -- until the Tarot was mentioned. I actually use Tarot cards from time to time, but more as an icebreaker parlor trick whenever I'm forced to go to Halloween gatherings or birthday parties, but I don't see it as a credulous way of sorting or profiling introverted people. However, I did read on and found the comparisons interesting. The definition of 'Artisan' seemed to apply to me.
