The Authority Gap

Guardian ‘best politics book of the year’
Times ‘best philosophy and ideas book of the year’
A Waterstones ‘best political book of the year’
Highly Commended, Business Book Awards 2022

Deeply researched, profoundly thoughtful and a book very much for the here and now: Mary Ann Sieghart’s The Authority Gap is the book she was probably born to write. It is both a warning tract for bombastic, dismissive men, and a cheerful manual for all ambitious women.”Andrew Marr

The Authority Gap provides a startling perspective on the unseen bias at work in our everyday lives, to reveal the scale of the gap that still persists between men and women. Marshalling a wealth of data with precision and insight, and including interviews with pioneering women such as Baroness Hale, Mary Beard and Bernadine Evaristo, this is a fresh feminist take on how to address and counteract systemic sexism in ways that benefit us all.
