As usual at the end of the semester I get students who tell me that they see the world in a whole new way after taking my human factors course. They way I (and many of my colleagues) teach Human Factors really does become a perspective rather than a set of theories or tools to use at work. On the very first day, I tell them that they will not only be better designers, but also better and dealing with friends, relatives, coworkers, and significant others. They don't believe me then, but by week 4 they sure do.
Maybe I should start a religion and become a preacher instead of a teacher???
