In which Susan Walsh takes a weird little personality test. I took the same test and got the following result:
Thoughtful to the extreme, you are often obsessed with perfection and the rules governing your own personal interests. Your world is black and white. You love to work within a logical system, such as language, computer programming, or mathematics. Manipulating a system that can be completely understood is a distinct pleasure to you, because of your confidence in the underlying veracity of your belief system. Because of your appreciation for logic and order, those who speak or think in a sloppy manner are apt to generate more than their share of wrath. Although very amiable, you are not drawn to friendships out of a sense of personal need. You are just as happy by yourself with a good book or puzzle. Because you are so involved with thought, you will on occasion have difficulty dealing with the day-to-day problems of a normal life. Taking out the trash, doing the dishes, these are often left until the last possible moment, if at all.
Translation: INTJ. I expect this result will not be uncommon among the Dread Ilk.
