egalitarianism as a hidden bias

a test at harvard's "project implicit" website allows you to detect your burning, latent, -ist (ageist, sexist, racist, etc) attitudes . tolerance.org says about the test:

Studies show people can be consciously committed to egalitarianism, and deliberately work to behave without prejudice, yet still possess hidden negative prejudices or stereotypes.

excuse me, is egalitarianism not a bias? not to tolerance.org, i suppose - but anyway...
there are hidden bias tests for gender, race, weight, age, and more. i took the gender test, which tested how much one associates males with science or females with the humanities. turns out, i'm the reverse of the stereotype. my result came back as:

Your data suggest a moderate association between science and Female relative to Male

this means i responded faster when associating female and science words than when associating males with science words. i suppose this makes some sense because i studied science in college (ah, organic chemistry, how i made sweet love to you!), and am a female, and that most of my classes were at least half female. of all respondents online, the site indicates that 47% show a moderate to strong bias in the opposite direction - strongly associating males with science. forty-eight percent, however, showed a slight bias or none at all, which is exciting news.
but my results are peculiar. all my societal cues would point otherwise as a child. my father was an engineer and my mother stayed home until i was in junior high. they raised me in a traditional rural area and went to a socially conservative university. i was subjected to the same media and societal pressures and influences as everyone else. however, my results are the opposite of what one would expect, likely because my direct experience with the question at hand pointed otherwise. amazing, the human mind...
