Kanter's study of tokens
Studying a large US corporation's sales force, Kanter (1977) found that when women are a tiny minority they are treated as 'tokens' symbolizing their group rather than as individuals, facing heightened visibility, stereotyping and isolation. She distinguished skewed, tilted and balanced groups by their proportions and argued that as the minority's share grows, its members can form alliances and change the culture. The argument connects to critiques of tokenism.
Entry into political science
Dahlerup (1988) examined how political culture and agendas changed as women's numbers grew in Nordic parliaments. She stressed that 'critical acts' by which women change institutions and resources matter more than numbers alone. The 30% figure was later widely used by international organizations and women's movements to demand gender quotas, and together with Phillips's (1995) 'politics of presence' it supported arguments for descriptive representation.
Empirical tests and reassessment
Bratton (2005) showed that even in state legislatures where women were few, women legislators actively introduced and passed women's interest bills, casting doubt on the theory. Grey (2006) and Beckwith and Cowell-Meyers (2007) argued that parties, institutions and agenda contexts matter as well as proportions. Childs and Krook (2008) proposed shifting the question from 'how many are present' to 'who actually drives change', focusing on critical actors of any gender.
FAQ
- What is critical mass theory in simple terms?
- When a minority such as women is only a handful, it remains symbolic, but past a certain share it can actually change the climate and policy.
- Is 30% a precise threshold?
- It is a widely used benchmark, but empirical studies have not consistently confirmed it, and many argue that actors and institutions driving change matter more than numbers.
