The Unicorn Law is a statement on tokenism formulated by Emma Jane Hogbin. She and Gabrielle Roth named it at Open Source Bridge in 2009. It states that: If you are a woman in Open Source, you will eventually give a talk about being a woman in Open Source. The Unicorn Law is a play on Godwin's Law. For those who are not familiar with it, Godwin's Law states "as a Usenet discussion grows longer, the probability of a comparison involving Nazis or Hitler approaches 1." In the Unicorn Law it is the probability of a woman in open source talking about being a woman in open source that approaches 1.
