I have to admit that I didn't know what the Bechdel test was until I read this article. In a nutshell, it is a very minimal test for gender bias in movies and TV that has three requirements:
1) two female characters
2) who talk to each other
3) about something besides men.
There is plenty of debate on the value of this standard, but it is intriguing to see what passes and what fails. The scores range from 7.5% for The Original Series (no surprise there) to 86.9% for Voyager (also no surprise). I was surprised that The Next Generation didn't score better than 44.9%. That means 98 out of 178 episodes do not feature a single conversation between two women that was not about men, despite the many female guest stars in addition to regular crew members Crusher, Troi, Guinan, and Yar.
Season 5 of Voyager scored 100%. I am in the middle of rewatching the whole series, inspired by my new pal Brianna Wu, who is an unabashed fan. I found it to be a great way to unwind after long days at App Camp For Girls, and maybe it even helped me in my role as camp director to ponder the question, "What Would Janeway Do?"
