Most of your instructors use the generic pronoun "he" when referring to psychologists, and the generic pronoun "she" when referring to administrative assistants. in your mind, you automatically think of psychologists as men and administrative assistants as women. why?

I'm guessing we do this because we think it's most common from previous knowledge. Back then women did one thing and men did the other so we associate it with that and pass it on to the next generation to characterize this without thinking but we know both can be either one now. It's just like associating pink with a girl and blue with a boy.
