I like to think I'm smarter than your average bear (though I often fear I'm a hell of a lot dumber). Taking the daily "Slate" quiz is enough to keep me grounded. I'm average, at best, on most quizzes, absolutely terrible at the Science and Vocabulary quizzes (foreign words, no fair!) and do best on Culture and News. 

It's a big comedown for an INTJ on the M&B, and a 5 on the Enneogram.
