Zack Snyder's movie adaptation of Alan Moore and Dave Gibbons' "Watchmen" may polarize fans until the end of days, but few can deny the the nerd chills they got watching Jackie Earle Haley's portrayal of Rorschach.

Now the psychology behind the vigilante's amorphous mask is available for all to see on Wikipedia, according to io9 via The New York Times.

Dr. Hermann Rorschach's projection-based test consists of 10 images, each of which have common responses that are used to gauge a respondent's state of mind. Or something - all of my college psych professors kind of thought the test was too old school to serve as anything more than fun pop psychology.

Even so, some psychologists are miffed because making the information readily available discredits the tests' validity in practice. After all, a participant who understands the interpretations in advance can't really be tested, can they?

But I'm not a scientist. I just like to watch crazy guys say "Hrmmmm."
