The Bechdel test asks whether a work of fiction features at least two women who talk to each other about something other than a man. The requirement that the two women must be named is sometimes added.
Only about half of all films meet these requirements, according to user-edited databases and the media industry press. The test is used as an indicator for the active presence of women in films and other fiction, and to call attention to gender inequality in fiction.
Also known as the Bechdel–Wallace test, the test is named after the American cartoonist Alison Bechdel, in whose comic strip Dykes to Watch Out For it first appeared in 1985. Bechdel credited the idea to a friend, Liz Wallace, and to the writings of Virginia Woolf. After the test became more widely discussed in the 2000s, a number of variants and tests inspired by it have been introduced.
