Science has historically perpetuated biases about gender, but new research is challenging these long-held assumptions. Angela Saini investigates the scientific fields of biology, psychology, and anthropology, examining how ingrained biases have shaped our understanding of men and women. The book revisits pivotal experiments and interviews contemporary scientists who are actively working to uncover the truth about the female sex, challenging the notion of male dominance and female passivity. Saini aims to present a more inclusive view of science that accurately represents women's biological and evolutionary history.

The book has been met with significant acclaim, with the Observer describing it as a 'battle cry' that is 'galvanising' its readership. It is recognized for its rigorous investigation into how scientific disciplines have historically misrepresented women. The work is praised for its ability to challenge deeply ingrained preconceptions about gender roles and biological determinism. Ultimately, Inferior is seen as an enlightening and empowering account that advocates for a more inclusive and accurate scientific perspective.
