Anna brought the Kingdomality personality test to my attention. Unlike other tests, this one doesn’t base itself around the Myers-Brigg personalities, and proposes a new set of personality types based around medieval roles. The writers of the test argue that today’s comanies are like old fashioned kingdoms, and they have roles that are simmilar to these older professions. There’s even a book.
The possible types include Bishop, Benevolent Ruler, Merchant, Dreamer-Minstrel, White Knight, Discoverer, Prime Minister, Black Knight, Doctor, Engineer-Builder, Scientist and Shepherd.
