Book cover of The Confidence Code by Katty Kay and Claire Shipman — psychology of confidence and leadership.

Summary

The Confidence Code explores the science, psychology, and social conditioning behind confidence, drawing on research in neuroscience, genetics, and behavioral science. Katty Kay and Claire Shipman argue that confidence — more than competence — is often the critical factor shaping leadership, opportunity, and success. While the book focuses primarily on women, its insights into risk-taking, self-belief, and action are broadly applicable to anyone navigating professional and personal challenges.
