The Story of the Theory of Critical Mass

The theory of a “critical mass” seems to live a life of its own, in spite of reservations expressed by researchers, my own reservations included. In debates about women's political representation, the importance of a certain number or percentage of women in political assemblies is often stressed. According to conventional wisdom, research has shown that it takes a certain minimum representation, for example, 30%, before the minority, here women, are able to make a substantial difference in politics.
