The Bem Sex Role Inventory was developed in 1971 by Dr. Sandra Lipsitz Bem. It characterizes your personality as masculine, feminine, androgynous, or undifferentiated. The BSRI is based on gender stereotypes, so what it's actually measuring is how well you fit into your traditional sex role. Thus, your score says as much about how our cultural expectations have changed over the last 35 years as it does about your personality.
The test consists of a list of 30 personal attributes. Rate each attribute on how accurately it describes you. (The original BSRI had 60 questions and offered seven choices for each attribute, but long tests are boring and OKCupid only allows four answers per question. Not that it makes much difference...) Finally, if you like this test, please rate it.
On with the test!
