Via the NADS message board, I stumbled upon one of those online quizzes (at OKCupid!) that happens to be about a topic I know something about: linguistics. Here's the LJ code they give you on the last page:
Language Scholar
You scored a 310 out of 400 on language knowledge.
Outstanding! You've scored higher than even most Anthropology students
would. You are probably a Linguistics or Anthropology Professor
yourself (or at least a Grad student). You may even speak several
languages and are possibly working on a new one. If not, then you just
have an endless drive to learn about the different cultures of our
world. Regardless, you are one of the gems of any society, always
promoting a deeper understanding amongst all people. Unless you cheated
of course.
My test tracked 1 variable How you compared to other people your age and gender:
You scored higher than 99% on knowledge
[Minus the stupid ad they tack onto the end.]
So, apparently despite having published peer-reviewed papers in linguistics, I score a mere 77.5% on a quiz of general knowledge about world languages. Bah!
