Why are there still so few female scientists? Despite the scientific ethos of universalism and inclusion, women continue to experience real social inequities as they struggle to gain recognition in the scientific community. Based on extensive interviews and backed by quantitative analysis, this compelling work exposes the hidden barriers, subtle exclusions, and unwritten rules that confront women at every juncture along the scientific career path—from childhood to retirement. Through vivid personal accounts the authors offer an illuminating and sobering view of the effects these obstacles have on the personal and professional lives of women. They argue that women can succeed in the scientific workplace by successfully managing "social capital," those networks and relationships scientists rely on for professional support and new ideas. This benchmark volume is vital reading for all scientists and social scientists—both male and female—and for women considering a scientific career.
